Executive Summary
The Pacific Project (project) proposes a General Plan Amendment and Rezone (GPA/Rezone) to change the land use from Industrial (I) to Specific Plan Area (SPA). The project consists of 449 residential units, including a mix of apartments, rowhomes, villas, and affordable flats on approximately 15.09 acres of the 33.2 -acre project site. Proposed residential units would include a mix of apartments within a five-story podium building, three- story rowhomes, three-story villas, and affordable flats within a four-story building. The project includes a total of 927 parking spaces and 134,985 square feet of common open space area. 68 of the 449 total units (15% of the total) would be designated as deed-restric ted affordable units (alternatively, the project reserves the option to contribute to the affo rdable housing fund by paying the in-lieu fee). The proposed project also includes landscaping, bio-retention areas, and circulation improvements. The remaining approximately 17.94 acres of the 33.2-acre project site would be preserved and restored as open space and habitat area. The proposed project would have a density of approximately 13.5 dwelling units per acre, including the open space and habitat area.
The project site is located in the western portion of the City of San Marcos. The project site is located within the San Diego Air Basin and is subject to the guidelines and regulations of the San Diego Air Pollution Control District (SDAPCD).
A
Airr Qualityy
The air quality impact analysis provides an evaluation of the potential for significant adverse impacts to the ambient air quality due to construction and operational em issions resulting from the project. Construction of the project would result in a temporary addition of pollutants to the local airshed caused by soil disturbance, fugitive dust emissions, and combustion pollutants from on-site construction equipment, as well as from off-site trucks hauling construction materials. The analysis concludes that the daily construction emissions would not exceed SDAPCD’s significance thresholds for criteria pollutants after implementation of mitigation, and would result in a less-than-significant impact.
Operational emissions for the project we r e a l s o f o u n d t o b e b e l o w S D A P C D ’ s s i g n i f i c a n c e t h r e s h o l d s ; t h e r e f o r e , impacts during project operation would be less than significant. Additionally, impacts to sensitive receptors during temporary construction activities and operation of the project would be less than significant. Lastly, project operation would not generate odors at levels that would cause a nuisance; therefore, impacts would be less than significant.
Greenhousee Gass Emissionss
The project’s potential effect on global climate change was evaluated, and emissions of greenhouse gases (GHGs) were estimated based on the use of construction equipment and vehicle trips associated with construction activities, as well as operational emissions once construction phases are complete. The project requires a general plan amendment because it is proposing a residential development on a site zoned as Industrial (I). Therefore, a GHG analysis was performed to analyze the emissions of the existing zoned site and the project. The project was shown to result in fewer GHG emissions than the existing land use designation, and would implement all applicable checklist items within the City of San Marcos’s 2020 Climate Action Plan. Therefore, the project would be consistent with the City of San Marcos’s 2020 Climate Action Plan.
Furthermore, the project would be consistent with and would not conflict with the applicable GHG-reducing strategies of the state, California Air Resources Board’s Scoping Plan, and San Diego Association of Government’s

1.1 Report Purpose and Scope
The purpose of this technical report is to assess the potential air quality and greenhouse gas (GHG) emissions impacts associated with construction and operation of the Pacific Project (project). This analysis uses the significance thresholds in Appendix G of the Californ ia Environmental Quality Act (CEQA) Guidelines (14 CCR 15000 et seq.) and the emissions-based significance thresholds recommended by the San Diego Air Pollution Control District (SDAPCD) and other applicable thresholds of significance.
This introductory section provides a description of the project and the project location. Section 2, Air Quality, describes the air quality–related environmental se tting, regulatory setting, existing air quality conditions, and thresholds of significance and analysis methodology, and presents an air quality impact analysis per Appendix G of the CEQA Guidelines. Section 3, Greenhouse Gas Emissions, follows the same format as Section 2 and describes the GHG emissions–related environmental setting, regulatory setting, existing climate change conditions, and thresholds of significance and analysis methodology, and presents a GHG emissions impact analysis per Appendix G of the CEQA Guidelines. Section 4, References Cited, includes a list of the references cited in this technical report. Section 5, List of Preparers, includes a list of those who prepared this technical report.
1.2 Regional and Local Setting
The project site is located in the land use jurisdiction of the City of San Marcos (City). The City is located within the San Diego Air Basin (SDAB) and is under the jurisdiction of the SDAPCD. The project site is located in the western portion of the City of San Marcos, at the northwest corn er of Las Posas Road and Linda Vista Drive. La Mirada Road abuts the site’s northern boundary and Pacific Street abuts the site’s western boundary. The Grand Plaza shopping center is located directly across Las Posas Drive. Light industrial uses are adjacent to the site’s northern, southern, and western boundaries, and Bradley Park is located across from the site’s southwestern corner.
1.3 Project Description
The approximately 33-acre project site is located in the western portion of the City, at the northwest corner of Las Posas Road and Linda Vista Drive. The project location and project site boundary are shown in Figure 1, Project Location, Figure 2, Project Site, and Figure 3, Conceptual Site Plan.
The 33.2-acre project site is an infill site located in the western portion of the City of San Marcos (City), at the northwest corner of S. Las Posas Road and Linda Vista Drive, comprised of Assessor’s Parcel Numbers 219-222- 01, 219-222-02, 219-222-03, and 219-222-04. La Mirada Drive abuts the site’s northern boundary, while South Pacific Street abuts the property’s western boundary. The Grand Plaza shopping center is located directly across Las Posas Road to the east. Light industrial uses are adjacent to the site’s northern, southern, and western boundary, and Bradley Park is located across from the site’s southwestern corner. Single- and multi-family residential uses are located to the west and south of Bradley Park.
The project consists of 449 residential units, including a mix of apartments, rowhomes, villas, and affordable flats on approximately 15.09 acres of the 33.2-acre proj ect site. Proposed residential units would include a

mix of apartments within a five-story podium building, three-story rowhomes, three-story villas, and affordable flats within a four-story building. The project includes a total of 927 parking spaces and 134,985 square feet of common open space area. 68 of the 449 total units (15% of the total) would be designated as deed-restricted affordable units (alternatively, the project reserves the option to contribute to the affordable housing fund by paying the in-lieu fee). The proposed project also includes landscaping, bio-retention areas, and circulation improvements. The remaining approximately 17.94 acres of the 33.2-acre project site would be preserved and restored as open space and habitat area. The proposed project would have a density of approximately 13.5 dwelling units per acre, including the open space and habitat area.
The project proposes a General Plan Amendment, Rezo ne, Specific Plan, Tentative Map, and Multi-Family Site Development Plan. The General Plan Amendment and Rezone would change the General Plan designation and Zoning from Industrial (I) to Specific Plan Area (SPA). The Specific Plan has been prepared with the intent to provide a comprehensive plan to ensure the efficient development of a new residential community. The Specific Plan serves as both a policy document and a regulatory document for the systematic implementation of the policies and go als of the General Plan. The Tentative Map presents specific lot configurations for the site. The Multi-Family Site Development Plan will configure the site for multi family dwelling units, street configuration, infrastructure, recreational open space, and private open space.
As part of the project, additional pedestrian connectivity would be provided along three of the adjacent street frontages. The project would provide a 6-foot sidewalk and Class II buffered bike lane along the project’s frontage on Pacific Street; the project would provide a 12-foot urban trail (shared use path) along the project’s frontage on Linda Vista Drive; and the project would also provide a 12-foot urban trail (shared use path) along the project’s frontage on La Mirada Drive. In addition to the proposed sidewalk and trail connections, the project would add a bus stop and shelter with a bus turnout along South Las Posas Road adjacent to the development area and would install a 4-way traffic signal at the intersection of Linda Vista Drive and Pacific Street. Furthermore, the project would upsize approximately 1,458-feet of existing water pipe from 8-inches to 12-inches and would convert approximately 1,400-feet of existing overhead power lines to underground along La Mirada.
1.4 Project Design Features
The project would consist of a GPA/Rezone to convert the existing Industrial (I) land use designation to Specific Plan Area (SPA). The project would be required to adhere to the following regulatory measures to ensure compliance with the applicable City of San Marcos Clim ate Action Plan (CAP) Checklist measures (City of San Marcos 2020):

2 Air Quality
2.1 Environmental Setting
2.1.1 Climate and Topography
The weather of the San Diego region, as in most of Southe rn California, is influenced by the Pacific Ocean and its semi-permanent high-pressure systems that result in dry, warm summers and mild, occasionally wet winters. The average summertime high temperature in the region is approximately 74°F, with highs approaching 76°F in August, on average. The average wintertime low temperat ure is approximately 49°F, although record lows have approached 48°F in January. Average precipitation in the local area is approximately 10 inches per year, with the bulk of precipitation falling between December through March (WRCC 2017).
The topography in the San Diego region varies greatly, from beaches in the west to mountains and desert in the east.
Along with local meteorology, topography influences the dispersal and movement of pollutants in the air basin. The mountains to the east prevent dispersal of pollutants in that direction and help trap them in inversion layers.
The interaction of ocean, land, and the Pacific High Pressure Zone maintains clear skies for much of the year and influences the direction of prevailing winds (westerly to northwesterly). Local terrain is often the dominant factor inland, and winds in inland mountainous areas tend to blow through the valleys during the day and down the hills and valleys at night.
2.1.2 Air Pollution Climatology
The SDAB is one of 15 air basins that geographically divi de California. The SDAB is currently classified as a federal nonattainment area for ozone (O 3), and a state nonattainment area for particulate matter less than or equal to 10 microns in diameter (coarse particulate matter [PM 10]), particulate matter less than or equal to 2.5 microns in diameter (fine particulate matter [PM2.5]), and O3.
The SDAB lies in the southwest corner of California an d comprises the entire San Diego region, covering 4,260 square miles, and it is an area of high air pollution potential. The SDAB experiences warm summers, mild winters, infrequent rainfalls, light winds, and moderate humidity. This usually mild climatological pattern is interrupted infrequently by periods of extremely hot weather, winter storms, or Santa Ana winds.
The SDAB experiences frequent temperature inversions. Subsidence inversions occur during the warmer months as descending air associated with the Pacific High Pressu re Zone meets cool marine air. The boundary between the two layers of air creates a temperature inversion that traps pollutants. Another type of inversion, a radiation inversion, develops on winter nights when air near the ground cools by heat radiation and the air aloft remains warm. The shallow inversion layer formed between these two air masses also can trap pollutants. As the pollutants become more concentrated in the atmosphere, photochemical reactions occur that produce O 3,
commonly known as smog (CARB 2019a).

Light daytime winds, predominantly from the west, further aggravate the condition by driving air pollutants inland, toward the mountains. During the fall and winter, air quality problems are created due to carbon monoxide (CO) and oxides of nitrogen (NOx) emissions. CO concentrations are generally higher in the morning and late evening. In the morning, CO levels are elevated due to cold temperat ures and the large number of motor vehicles traveling.
Higher CO levels during the late evenings are a result of stagnant atmospheric conditions trapping CO in the area.
Since CO is produced almost entirely from automobiles, the highest CO concentrations in the SDAB are associated with heavy traffic. Nitrogen dioxide (NO2) levels are also generally higher during fall and winter days.
Under certain conditions, atmospheric oscillation results in the offshore transport of air from the Los Angeles region to San Diego County. This often produces high O 3 concentrations, as measured at air pollutant monitoring stations within San Diego County. The transport of air pollutants from Los Angeles to San Diego has also occurred within the stable layer of the elevated subsidence inversion, where high levels of O3 are transported.
2.1.3 Sensitive Receptors
Some land uses are considered more sensitive to changes in air quality than others, depending on the population groups and the activities involved. People most likely to be affected by air pollution, as identified by the California Air Resources Board (CARB), include children, older adults, and people with cardiovascular and chronic respiratory diseases. Sensitive receptors include residenc es, schools, playgrounds, childcare centers, long-term healthcare facilities, rehabilitation centers, convalescent centers, and retirement homes. The closest existing sensitive receptors to the project site are single-family residents located approximately 150 feet west of the northwest corner of the project site, 1,420 feet southwest of the project site, TERI Country School located approximately 1,100 feet southeast of the project site, and La Mirada Academy located approximately 1,600 feet northeast of the project site.
2.1.4 Pollutants and Effects
2.1.4.1 Criteria Air Pollutants
Criteria air pollutants are defined as pollutants for which the federal and state governments have established ambient air quality standards, or criteria, for outdoor concentrations to protect public health. The federal and state standards have been set, with an adequate margin of safety, at levels above which concentrations could be harmful to human health and welfare. These standards are designed to protect the most sensitive persons from illness or discomfort. Pollutants of concern include O
3, NO2, CO, sulfur dioxide (SO2), PM10, PM2.5, and lead. These pollutants, as well as toxic air contaminants (TACs), are discussed in the following text. 1 In California, sulfates, vinyl chloride, hydrogen sulfide, and visibility-reducing particles are also regulated as criteria air pollutants.
OOzone. O3 is a strong-smelling, pale blue, reactive, toxic chemic al gas consisting of three oxygen atoms. It is a secondary pollutant formed in the atmosphere by a photochemical process involving the sun’s energy and O 3 precursors. These precursors are mainly NO x and volatile organic compounds (VOCs). The maximum effects of precursor emissions on O3 concentrations usually occur several hours after they are emitted and many miles from 1 The descriptions of health effects for each of the criteria air pollutants associated with project construction and operations are based on the U.S. Environmental Protection Agency’s “Criteria Air Pollutants” (EPA 2016a) and CARB’s “Glossary of Air Pollution Terms” (CARB 2019a).

the source. Meteorology and terrain play major roles in O 3 formation, and ideal conditions occur during summer and early autumn on days with low wind speeds or stagnant air, warm temperatures, and cloudless skies. O 3 exists in the upper atmosphere O 3 layer (stratospheric O3) and at the Earth’s surface in the troposphere (ground- level O 3).2 The O 3 that the U.S. Environmental Protection Agency (EPA) and CARB regulate as a criteria air pollutant is produced close to the ground level, wher e people live, exercise, and breathe. Ground-level O 3 is a harmful air pollutant that causes numerous adverse health effects and is thus considered “bad” O 3.
Stratospheric, or “good,” O3 occurs naturally in the upper atmosphere, where it reduces the amount of ultraviolet light (i.e., solar radiation) entering the Earth’s atmosphere. Without the protection of the beneficial stratospheric O
3 layer, plant and animal life would be seriously harmed.
O3 in the troposphere causes numerous adverse health effects; short-term exposures (lasting for a few hours) to O3 at levels typically observed in Southern California can result in breathing pattern changes, reduction of breathing capacity, increased susceptibility to infections, inflammation of the lung tissue, and some immunological changes (EPA 2013).
Inhalation of O3 causes inflammation and irritation of the tissues lining human airways, causing and worsening a variety of symptoms. Exposure to O 3 can reduce the volume of air that the lungs breathe in, thereby causing shortness of breath. O 3 in sufficient doses increases the permeability of lung cells, rendering them more susceptible to toxins and microorganisms. The occurrence and severity of health effects from O 3 exposure vary widely among individuals, even when the dose and the duration of exposure are the same. Research shows adults and children who spend more time outdoors participating in vigorous physical activities are at greater risk from the harmful health effects of O
3 exposure. Although there are relatively few studies on the effects of O 3 on children, the available studies show that children are no mo re or less likely to suffer harmful effects than adults.
However, there are a number of reasons why children may be more susceptible to O 3 and other pollutants.
Children and teens spend nearly twice as much time outdoors and engaged in vigorous activities as adults.
Children breathe more rapidly than adults and inhale mo re pollution per pound of their body weight than adults.
Also, children are less likely than adults to notice their own symptoms and avoid harmful exposures. Further research may be able to better distinguish between health effects in children and adults. Children, adolescents, and adults who exercise or work outdoors, where O 3 concentrations are the highest, are at the greatest risk of harm from this pollutant (CARB 2019b).
Nitrogenn Dioxide. NO2 is a brownish, highly reactive gas that is present in all urban atmospheres. The major mechanism for the formation of NO 2 in the atmosphere is the oxidation of the primary air pollutant nitric oxide (NO), which is a colorless, odorless gas. NO x plays a major role, together with VOCs, in the atmospheric reactions that produce O3. NOx is formed from fuel combustion under high temperature or pressure. In addition, NO x is an important precursor to acid rain and may affect both terrestrial and aquatic ecosystems. The two major emissions sources are transportation and stationary fuel combustion sources, such as electric utility and industrial boilers.
A large body of health science literature indicates that exposure to NO 2 can induce adverse health effects. The strongest health evidence, and the health basis for the ambient air quality standards for NO 2, results from controlled human exposure studies that show that NO 2 exposure can intensify responses to allergens in allergic asthmatics. In addition, a number of epidemiologica l studies have demonstrated associations between NO 2 exposure and premature death, cardiopulmonary effects, decreased lung function growth in children, respiratory 2 The troposphere is the layer of the Earth’s atmosphere nearest to the surface of the Earth. The troposphere extends outward about 5 miles at the poles and about 10 miles at the equator.

symptoms, emergency room visits for asthma, and intensified allergic responses. Infants and children are particularly at risk because they have disproportionately higher exposure to NO 2 than adults due to their greater breathing rate for their body weight and their typically greater outdoor exposure duration. Several studies have shown that long-term NO2 exposure during childhood, the period of rapid lung growth, can lead to smaller lungs at maturity in children with higher levels of exposure compared to children with lower exposure levels. In addition, children with asthma have a greater degree of airway responsiveness compared with adult asthmatics. In adults, the greatest risk is to people who have chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease (CARB 2019c).
C
Carbonn Monoxide. CO is a colorless, odorless gas formed by the incomplete combustion of hydrocarbon, or fossil fuels. CO is emitted almost exclusively from motor vehicles, power plants, refineries, industrial boilers, ships, aircraft, and trains. In urban areas, such as the project location, automobile exhaust accounts for the majority of CO emissions. CO is a nonreactive air pollutant that dissipates relatively quickly; therefore, ambient CO concentrations generally follow the spatial and temporal distributions of vehicular traffic. CO concentrations are influenced by local meteorological conditions—primarily wind speed, topography, and atmospheric stability. CO from motor vehicle exhaust can become locally concentrated when surface-based temperature inversions are combined with calm atmospheric conditions, which is a ty pical situation at dusk in urban areas from November through February. The highest levels of CO typically occu r during the colder months of the year, when inversion conditions are more frequent.
CO is harmful because it binds to hemoglobin in the blood, reducing the ability of blood to carry oxygen. This interferes with oxygen delivery to the body’s organs. The most common effects of CO exposure are fatigue, headaches, confusion and reduced mental alertness, light-headedness, and dizziness due to inadequate oxygen delivery to the brain. For people with cardiovascular disease, short-term CO exposure can further reduce their body’s already compromised ability to respond to the increased oxygen demands of exercise, exertion, or stress. Inadequate oxygen delivery to the heart muscle leads to chest pain and decreased exercise tolerance. Unborn babies whose mothers experience high l e v e l s o f C O ex p o s u r e d u ri n g p r e g n a n c y a r e a t r i s k o f a dverse developmental effects. Unborn babies, infants, older adults, and people with anemia or with a history of heart or respiratory disease are most likely to experience health effects with exposure to elevated levels of CO (CARB 2019d).
Sulfurr Dioxide. SO2 is a colorless, pungent gas formed primarily from incomplete combustion of sulfur-containing fossil fuels. The main sources of SO 2 are coal and oil used in power plants and industries; as such, the highest levels of SO2 are generally found near large industrial complexes. In recent years, SO 2 concentrations have been reduced by the increasingly stringent controls placed on stationary source emissions of SO 2 and limits on the sulfur content of fuels.
Controlled human exposure and epidemiological studies show that children and adults with asthma are more likely to experience adverse responses with SO2 exposure compared with the non-asthmatic population. Effects at levels near the 1-hour standard are those of asthma exacerbation, including bronchoconstriction accompanied by symptoms of respiratory irritation such as wheezing, shor tness of breath, and chest tightness, especially during exercise or physical activity. Also, exposure at elevated levels of SO 2 (above 1 parts per million [ppm]) results in increased incidence of pulmonary symptoms and disease, decreased pulmonary function, and increased risk of mortality. Older adults and people with cardiovascular disease or chronic lung disease (such as bronchitis or emphysema) are most likely to experience these adverse effects (CARB 2019e).

SO2 is of concern because it is a direct respiratory irritant and because it contributes to the formation of sulfate and sulfuric acid in particulate matter. People with asthma are of particular concern because they have increased baseline airflow resistance and because their SO2-induced increase in airflow resistance is greater than in healthy people, and it increases with the severity of their asthma. SO 2 is thought to induce airway constriction via neural reflexes involving irritant receptors in the airways (NRC 2005).
PParticulatee Matter. Particulate matter (PM) pollution consists of very small liquid and solid particles floating in the air, which can include smoke, soot, dust, salts, acid s, and metals. PM can form when gases emitted from industries and motor vehicles undergo chemical reactions in the atmosphere. PM2.5 and PM10 represent fractions of particulate matter. Coarse particulate matter (PM10) consists of particulate matter that is 10 microns or less in diameter and is about 1/7 the thickness of a human hair. Major sources of PM 10 include crushing or grinding operations; dust stirred up by vehicles traveling on roads; wood-burning stoves and fireplaces; dust from construction, landfills, and agriculture; wildfires and brush/waste burning; industrial sources; windblown dust from open lands; and atmospheric chemical and ph otochemical reactions. Fine particulate matter (PM 2.5) consists of particulate matter that is 2.5 microns or less in diameter and is roughly 1/28 the diameter of a human hair. PM2.5 results from fuel combustion (e.g., from motor vehicles and power generation and industrial facilities), residential fireplaces, and woodstoves. In addition, PM 2.5 can be formed in the atmosphere from gases such as sulfur oxides (SOx), NOx, and VOCs.
PM2.5 and PM 10 pose a greater health risk than larger-size particles. When inhaled, these tiny particles can penetrate the human respiratory system’s natural defenses and damage the respiratory tract. PM2.5 and PM10 can increase the number and severity of asthma attacks, ca use or aggravate bronchitis and other lung diseases, and reduce the body’s ability to fight infections. Very small particles of substances such as lead, sulfates, and nitrates can cause lung damage directly or be absorbed into the bloodstream, causing damage elsewhere in the body.
Additionally, these substances can transport adsorbed gases such as chlorides or ammonium into the lungs, also causing injury. Whereas PM
10 tends to collect in the upper portion of the respiratory system, PM2.5 is so tiny that it can penetrate deeper into the lungs and damage lung ti ssue. Suspended particulates also damage and discolor surfaces on which they settle and produce haze and reduce regional visibility.
A number of adverse health effects have been associated with exposure to PM2.5 and PM10. For PM2.5, short-term exposures (up to 24-hour duration) have been associated with premature mortality, increased hospital admissions for heart or lung causes, acute and chronic bronchitis, asthma attacks, emergency room visits, respiratory symptoms, and restricted activity days. These adverse health effects have been reported primarily in infants, children, and older adults with preexisting heart or lung diseases. In addition, of all of the common air pollutants, PM
2.5 is associated with the greatest proportion of adverse health effects related to air pollution, both in the United States and worldwide based on the World Health Organization’s Global Burden of Disease Project.
Short-term exposures to PM 10 have been associated primarily with worsening of respiratory diseases, including asthma and chronic obstructive pulmonary disease, leadin g to hospitalization and emergency department visits (CARB 2017a).
Long-term exposure (months to years) to PM 2.5 has been linked to premature death, particularly in people who have chronic heart or lung diseases, and reduced lung function growth in children. The effects of long-term exposure to PM 10 are less clear, although several studies suggest a link between long-term PM 10 exposure and respiratory mortality. The International Agency for Research on Cancer published a review in 2015 that concluded that PM in outdoor air pollution causes lung cancer (CARB 2017a).

LLead. Lead in the atmosphere occurs as particulate matter. Sources of lead include leaded gasoline; the manufacturing of batteries, paints, ink, ceramics, and am munition; and secondary lead smelters. Prior to 1978, mobile emissions were the primary source of atmospheric lead. Between 1978 and 1987, the phaseout of leaded gasoline reduced the overall inventory of airborne lead by nearly 95%. With the phaseout of leaded gasoline, secondary lead smelters, battery recycling, and manufacturing facilities are becoming lead-emissions sources of greater concern.
Prolonged exposure to atmospheric lead poses a serious threat to human health. Health effects associated with exposure to lead include gastrointestinal disturbances, anemia, kidney disease, and in severe cases, neuromuscular and neurological dysfunction. Of particular concern are low-level lead exposures during infancy and childhood. Such exposures are associated with de crements in neurobehavioral performance, including intelligence quotient (IQ) performance, psychomotor perf ormance, reaction time, and growth. Children are highly susceptible to the effects of lead.
Sulfates.. Sulfates are the fully oxidized form of sulfur, wh ich typically occur in combination with metals or hydrogen ions. Sulfates are produced from reactions of SO 2 in the atmosphere and can result in respiratory impairment, as well as reduced visibility.
Vinyll Chloride.. Vinyl chloride is a colorless gas with a mild, sweet odor, which has been detected near landfills, sewage plants, and hazardous waste sites due to the mi crobial breakdown of chlorinated solvents. Short-term exposure to high levels of vinyl chloride in air can cause nervous system effects, such as dizziness, drowsiness, and headaches. Long-term exposure through inhalation can cause liver damage, including liver cancer.
Hydrogenn Sulfide. Hydrogen sulfide is a colorless and flammable gas that has a characteristic odor of rotten eggs.
Sources of hydrogen sulfide include geothermal power plants, petroleum refineries, sewers, and sewage treatment plants. Exposure to hydrogen sulfide can result in nuisance odors, as well as headaches and breathing difficulties at higher concentrations.
Visibility-Reducingg Particles.. Visibility-reducing particles are any particles in the air that obstruct the range of visibility. Effects of reduced visibility can include obsc uring the viewshed of natural scenery, reducing airport safety, and discouraging tourism. Sources of visibility-reducing particles are the same as for PM2.5.
Volatilee Organicc Compounds. Hydrocarbons are organic gases that are formed from hydrogen and carbon, and sometimes other elements. Hydrocarbons that contribute to formation of O3 are referred to and regulated as VOCs.
Combustion engine exhaust, oil refineries, and fossil-fueled power plants are sources of hydrocarbons. Other sources of hydrocarbons include evaporation from petroleum fuels, solvents, dry-cleaning solutions, and paint.
The primary health effects of VOCs result from the formation of O 3 and its related health effects. High levels of VOCs in the atmosphere can interfere with oxygen intake by reducing the amount of available oxygen through displacement. Carcinogenic forms of hydrocarbons, such as benzene, are considered TACs. There are no separate health standards for VOCs as a group.
2.1.4.2 Non-Criteria Air Pollutants
Toxicc Airr Contaminants. A substance is considered toxic if it has the potential to cause adverse health effects in humans, including increasing the risk of cancer upon exposure, or acute and/or chronic noncancer health effects.
A toxic substance released into the air is considered a TAC. TACs are identified by federal and state agencies

based on a review of available scientific evidence. In California, TACs are identified through a two-step process that was established in 1983 under the Toxic Air Contaminant Identification and Control Act. This two-step process of risk identification and risk management and reduction was designed to protect residents from the health effects of toxic substances in the air. In additi on, the California Air Toxics “Hot Spots” Information and Assessment Act, Assembly Bill (AB) 2588, was enacted by the legislature in 1987 to address public concern over the release of TACs into the atmosphere. The law requires facilities emitting toxic substances to provide local air pollution control districts with information that will allow an assessment of the air toxics problem, identification of air toxics emissions sources, location of resulting hotspots, notification of the public exposed to significant risk, and development of effective strategies to reduce potential risks to the public over 5 years.
Examples of TACs include certain aromatic and chlorinated hydrocarbons, certain metals, and asbestos. TACs are generated by a number of sources, including stationary sources, such as dry cleaners, gas stations, combustion sources, and laboratories; mobile sources, such as automobiles; and area sources, such as landfills. Adverse health effects associated with exposure to TACs may include carcinogenic (i.e., cancer-causing) and noncarcinogenic effects. Noncarcinogenic effects typically affect one or more target organ systems and may be experienced on either short-term (acute) or long-term (chronic) exposure to a given TAC.
D
Diesell Particulatee Matter.. Diesel particulate matter (DPM) is part of a complex mixture that makes up diesel exhaust. Diesel exhaust is composed of two phases, gas and particle, both of which contribute to health risks.
More than 90% of DPM is less than 1 micrometer in di ameter (about 1/70 the diameter of a human hair), and thus is a subset of PM 2.5 (CARB 2019f). DPM is typically composed of carbon particles (“soot,” also called black carbon) and numerous organic compounds, including more than 40 known cancer-causing organic substances.
Examples of these chemicals include polycyclic aromatic hydrocarbons, benzene, formaldehyde, acetaldehyde, acrolein, and 1,3-butadiene (CARB 2019f). CARB classified “particulate emissions from diesel-fueled engines” (i.e., DPM) (17 CCR 93000) as a TAC in August 1998. DPM is emitted from a broad range of diesel engines: on- road diesel engines of trucks, buses, and cars, and off-road diesel engines including locomotives, marine vessels, and heavy-duty construction equipment, among others. Approximately 70% of all airborne cancer risk in California is associated with DPM (CARB 2000). To reduce the cancer risk associated with DPM, CARB adopted a diesel risk reduction plan in 2000 (CARB 2000). Because it is part of PM
2.5, DPM also contributes to the same non-cancer
health effects as PM 2.5 exposure. These effects include premature death; hospitalizations and emergency department visits for exacerbated chronic heart and lung disease, including asthma; increased respiratory symptoms; and decreased lung function in children. Se veral studies suggest that exposure to DPM may also facilitate development of new allergies. Those most vulnerable to non-cancer health effects are children, whose lungs are still developing, and older adults, who often have chronic health problems (CARB 2019f).
Odorouss Compounds. Odors are generally regarded as an annoyance rather than a health hazard. Manifestations of a person’s reaction to odors can range from psychological (e.g., irritation, anger, or anxiety) to physiological (e.g., circulatory and respiratory effects, nausea, vomiting, and headache). The ability to detect odors varies considerably among the population and overall is quite su bjective. People may have different reactions to the same odor. An odor that is offensive to one person may be perfectly acceptable to another (e.g., coffee roaster).
An unfamiliar odor is more easily detected and is more likely to cause complaints than a familiar one. In a phenomenon known as odor fatigue, a person can become desensitized to almost any odor, and recognition may only occur with an alteration in the intensity. The occurrence and severity of odor impacts depend on the nature, frequency, and intensity of the source; wind speed and direction; and the sensitivity of receptors.

VValleyy Fever. Coccidioidomycosis, more commonly known as “Valley Fever,” is an infection caused by inhalation of the spores of the Coccidioides immitis fungus, which grows in the soils of the southwestern United States. When fungal spores are present, any activity that disturbs the soil, such as digging, grading, or other earth-moving operations, can cause the spores to become airborne an d thereby increase the risk of exposure. The ecologic factors that appear to be most conducive to survival and replication of the spores are high summer temperatures, mild winters, sparse rainfall, and alkaline sandy soils.
Valley Fever has been reported in most counties in California, with approximately 70% of the cases occurring within six counties: Kern, Kings, San Luis Obispo, Fresno, Tulare, and Madera Counties. The reported number of cases in California was 7,515 cases in 2018, with the Coccidioidomycosis incidence rate of 18.8 per 100,000 population in 2018. In San Diego County, the numbers of Valley Fever cases reported was 1,765 cases in 2018, or an incidence rate of 5.5 per 100,000 population (CDPH 2019; Nelson, pers. comm. 2019). The project site is wholly contained within the 92078 zip code, and within the 92078 zip code there were 3.1 cases per 100,000 people per year of Coccidioidomycosis between 2009 and 2018 (Nelson, pers. comm. 2019).
Even if present at a site, earth-moving activities may not result in increased incidence of Valley Fever. Propagation of Coccidioides immitis is dependent on climatic conditions, with the potential for growth and surface exposure highest following early seasonal rains and long dry spells. Coccidioides immitis spores can be released when filaments are disturbed by earth-moving activities, although receptors must be exposed to and inhale the spores to be at increased risk of developing Valley Fever. Moreover, exposure to Coccidioides immitis does not guarantee that an individual will become ill—approximately 60% of people exposed to the fungal spores are asymptomatic and show no signs of an infection (USGS 2000).
2.2 Regulatory Setting
2.2.1 Federal
The federal Clean Air Act, passed in 1970 and last amended in 1990, forms the basis for the national air pollution control effort. The EPA is responsible for implementing most aspects of the Clean Air Act, including setting National Ambient Air Quality Standards (NAAQS) for ma jor air pollutants; setting hazardous air pollutant standards; approving state attainment plans; setting motor vehicle emission standards; issuing stationary source emission standards and permits; and establishing acid rain control measures, stratospheric O 3 protection
measures, and enforcement provisions. Under the Clean Air Act, NAAQS are established for the criteria pollutants O3, CO, NO2, SO2, PM10, PM2.5, and lead.
The NAAQS describe acceptable air quality conditions designed to protect the health and welfare of the citizens of the nation. The NAAQS (other than for O3, NO2, SO2, PM10, PM2.5, and those based on annual averages or arithmetic mean) are not to be exceeded more than once per year. NAAQS for O3, NO2, SO2, PM10, and PM2.5 are based on statistical calculations over 1- to 3-year periods, depending on the pollutant. The Clean Air Act requires the EPA to reassess the NAAQS at least every 5 years to determine whether adopted standards are adequate to protect public health based on current scientific evidence. States with areas that exceed the NAAQS must prepare a state implementation plan that demonstrates how those areas will attain the standards within mandated time frames.

2.2.2 State
The federal Clean Air Act delegates the regulation of air pollution control and the enforcement of the NAAQS to the states. In California, the task of air quality management and regulation has been legislatively granted to CARB, with subsidiary responsibilities assigned to air quality management districts and air pollution control districts at the regional and county levels. CARB, which became part of the California Environmental Protection Agency in 1991, is responsible for ensuring implementation of the California Clean Air Act of 1988, responding to the federal Clean Air Act, and regulating emissions from motor vehicles and consumer products.
CARB has established California Ambient Air Quality Standards (CAAQS), which are generally more restrictive than the NAAQS. The CAAQS describe adverse conditions; that is, pollution levels must be below these standards before a basin can attain the standard. Air quality is considered “in attainment” if pollutant levels are continuously below the CAAQS and violate the standards no more than once each year. The CAAQS for O 3, CO, SO2
(1-hour and 24-hour), NO2, PM10, PM2.5, and visibility-reducing particles are values that are not to be exceeded. All others are not to be equaled or exceeded. The NAAQS and CAAQS are presented in Table 1.

Notes:: CAAQS = California Ambient Air Quality Standards; NAAQS = National Ambient Air Quality Standards; O 3 = ozone; ppm = parts per million by volume; Pg/m3 = micrograms per cubic meter; NO2 = nitrogen dioxide; CO = carbon monoxide; mg/m 3= milligrams per cubic meter; SO2 = sulfur dioxide; PM10 = coarse particulate matter; PM2.5 = fine particulate matter. a California standards for O 3, CO, SO 2 (1-hour and 24-hour), NO 2, suspended particulate matter—PM 10, PM 2.5, and visibility- reducing particles, are values that are not to be exceeded. All others are not to be equaled or exceeded. CAAQS are listed in t he Table of Standards in Section 70200 of Title 17 of the California Code of Regulations. b National standards (other than O 3, NO 2, SO 2, particulate matter, and those based on annual averages or annual arithmetic mean) are not to be exceeded more than once a year. The O 3 standard is attained when the fourth-highest 8-hour concentration measured at each site in a year, averaged over 3 years, is equal to or less than the standard. For PM 10, the 24-hour standard is attained when the expected number of days per calend ar year with a 24-hour average concentration above 150 μg/m3 is equal to or less than 1. For PM 2.5, the 24-hour standard is attained when 98% of the daily concentrations, averaged over 3 years, are equal to or less than the standard.
c Concentration expressed first in units in which it was promulga ted. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 torr . Most measurements of air quality are to be corrected to a reference temperature of 25°C and a reference pressure of 760 torr ; ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas.
d National primary standards: the levels of air quality necessary, with an adequate margin of safety to protect the public health. e National secondary standards: the levels of air quality necessar y to protect the public welfare from any known or anticipated adverse effects of a pollutant.
f On October 1, 2015, the primary and secondary NAAQS for O3 were lowered from 0.075 ppm to 0.070 ppm. g To attain the 1-hour national standard, the 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations at each site must not exceed 100 parts per billion ( ppb). Note that the national 1- hour standard is in units of ppb. California standards are in units of ppm. To directly compar e the national 1-hour standard to the California standards the units can be converted from ppb to ppm. In this case, the national standard of 100 ppb is identical to 0.100 ppm. h On June 2, 2010, a new 1-hour SO2 standard was established and the existing 24-hour and annual primary standards were revoked.
To attain the 1-hour national standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each site must not exceed 75 ppb. The 1971 SO2 national standards (24-hour and annual) remain in effect until 1 year after an area is designated for the 2010 standard, except that in areas designated nonattainment of the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved. i On December 14, 2012, the national annual PM 2.5 primary standard was lowered from 15 Pg/m3 to 12.0 Pg/m3. The existing national 24-hour PM2.5 standards (primary and secondary) were retained at 35 Pg/m3, as was the annual secondary standard of 15 μg/m3. The existing 24-hour PM 10 standards (primary and secondary) of 150 Pg/m3 also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years. j CARB has identified lead and vinyl chloride as TACs with no threshold level of exposure for adverse health effects determined. These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants. k The national standard for lead was revised on October 15, 20 08, to a rolling 3-month average. The 1978 lead standard (1.5 μg/m3 as a quarterly average) remains in effect until 1 year after an area is designated for the 2008 standard, except that in

areas designated nonattainment for the 1978 standard, the 1978 st andard remains in effect un til implementation plans to attain or maintain the 2008 standard are approved.
TToxicc Airr Contaminantss
The state Air Toxics Program was established in 1983 under AB 1807 (Tanner). The California TAC list identifies more than 700 pollutants, of which carcinogenic and noncarcinogenic toxicity criteria have been established for a subset of these pollutants pursuant to the California Health and Safety Code. In accordance with AB 2728, the state list includes the (federal) hazardous air pollutants. In 1987, the Legislature enacted the Air Toxics “Hot Spots” Information and Assessment Act of 1987 (AB 2588) to address public concern over the release of TACs into the atmosphere. AB 2588 law requires facilities emitting toxic substances to provide local air pollution control districts with information that will allow an assessment of the air toxics problem, identification of air toxics emissions sources, location of resulting hotspots, notifi cation of the public exposed to significant risk, and development of effective strategies to reduce potential risks to the public over 5 years. TAC emissions from individual facilities are quantified and prioritized. “High-priority” facilities are required to perform a health risk assessment, and if specific thresholds are exceeded, the fa cility operator is required to communicate the results to the public in the form of notices and public meetings.
In 2000, CARB approved a comprehensive Diesel Risk Reduction Plan to reduce diesel emissions from new and existing diesel-fueled vehicles and engines (CARB 2000). The regulation is anticipated to result in an 80% decrease in statewide diesel health risk by 2020 compared with the diesel risk in 2000. Additional regulations apply to new trucks and diesel fuel, including the On-Road Heavy Duty Diesel Vehicle (In-Use) Regulation, the On- Road Heavy Duty (New) Vehicle Program, the In-Use Off- Road Diesel Vehicle Regulation, and the New Off-Road Compression-Ignition (Diesel) Engines and Equipment Program. These regulations and programs have timetables by which manufacturers must comply and existing operators must upgrade their diesel-powered equipment. There are several airborne toxic control measures that reduce diesel emissions, including In-Use Off-Road Diesel-Fueled Fleets (13 CCR 2449 et seq.) and In-Use On-Road Diesel-Fueled Vehicles (13 CCR 2025).
Californiaa Healthh andd Safetyy Codee Sectionn 417000
Section 41700 of the Health and Safety Code states that a person must not discharge from any source whatsoever quantities of air contaminants or other material that cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public; or that endanger the comfort, repose, health, or safety of any of those persons or the public; or that cause, or have a natural tendency to cause, injury or damage to business or property. This section also applies to sources of objectionable odors.
2.2.3 Local
Sann Diegoo Airr Pollutionn Controll Districtt
Although CARB is responsible for the regulation of mobile emission sources within the state, local air quality management districts and air pollution control districts are responsible for enforcing standards and regulating stationary sources. The project site is located within the SDAB and is subject to SDAPCD guidelines and regulations. In San Diego County, O
3 and PM are the pollutants of main concern, because exceedances of the CAAQS for those pollutants are experienced in San Diego County in most years. For this reason, the SDAB has
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT
13170
22 February 2023
been designated as a nonattainment area for the state PM 10, PM2.5, and O 3 (1-hour and 8-hour) standards. The SDAB is also designated as a federal O3 marginal nonattainment area for the 2008 8-hour NAAQS for O3.
SDAPCD and the San Diego Association of Governments (SANDAG) are responsible for developing and implementing the clean air plan for attainment and maintenance of the ambient air quality standards in the SDAB. The Regional Air Quality Strategy (RAQS) for the SDAB was initially adopted in 1991 and is updated every 3 years (most recently in 2016). The RAQS outlines SDAPC D’s plans and control measures designed to attain the CAAQS for O
3. The RAQS relies on information from CARB and SANDAG, including mobile and area source emissions, as well as information regarding projected growth in San Diego County and the cities in the County, to project future emissions and then determine from that the strategies necessary for the reduction of emissions through regulatory controls. CARB mobile source emission projections and SANDAG growth projections are based on population, vehicle trends, and land use plans developed by the County and the cities in the County as part of development of their general plans.
The 8-Hour Ozone Attainment Plan for San Diego County indicated that local controls and state programs would allow the region to reach attainment of the federal 8-hour O 3 standard by 2018 (SDAPCD 2016). In this plan, SDAPCD relied on the RAQS to demonstrate how the region will comply with the federal O 3 standard. The RAQS details how the region will manage and reduce O 3 precursors (NO x and VOCs) by identifying measures and regulations intended to reduce these contaminants. The control measures identified in the RAQS generally focus on stationary sources; however, the emissions inventories and projections in the RAQS address all potential sources, including those under the authority of CARB and the EPA. Incentive programs for reduction of emissions from heavy-duty diesel vehicles, off-road equipment, and school buses are also established in the RAQS. In response to court decisions, some elements in the 8-hour Ozone Attainment Plan for San Diego County required updates. CARB staff prepared the 2018 Updates to the Cali fornia State Implementation Plan (SIP) to update SIP elements for nonattainment areas throughout the state. The applicable attainment date for San Diego County is in 2021.
In December 2005, the SDAPCD prepared a report titled “Measures to Reduce Particulate Matter in San Diego County” to address implementation of Senate Bill (SB) 656 in San Diego County (SB 656 required additional controls to reduce ambient concentrations of PM
10 and PM 2.5). In the report, the SDAPCD evaluates
implementation of source-control measures that would reduce PM emissions associated with residential wood combustion (SDAPCD 2005).
The SDAPCD is responsible for planning, implementing, and enforcing federal and state ambient standards in the SDAB. The following rules and regulations would apply to the project:
x S
SDAPCDD Regulationn II:: Permits;; Rulee 20.2:: Neww Sourcee Revieww Non-Majorr Stationaryy Sources. Requires new or modified stationary source units (that are not major stationary sources) with the potential to emit 10 pounds per day or more of VOC, NO x, SO x, or PM 10 to be equipped with best available control technology. For those units with a potential to emit above Air Quality Impact Assessments Trigger Levels, the units must demonstrate that such emissions would not violate or interfere with the attainment of any national air quality standard (SDAPCD 1998).
x SDAPCDD Regulationn IV:: Prohibitions;; Rulee 50:: Visiblee Emissions. Prohibits discharge into the atmosphere from any single source of emissions whatsoever any air contaminant for a period or periods aggregating more than 3 minutes in any period of 60 consecutive minutes that is darker in shade than that designated as Number 1 on the Ringelmann Chart, as published by the United States Bureau of Mines, or

Prohibits the discharge, from any source, of such quantities of air contaminants or other materials that cause or have a tendency to cause injury, detriment, nuisance, annoyance to people and/or the public, or damage to any business or property (SDAPCD 1976).
x
SDAPCDD Regulationn IV:: Prohibitions;; Rulee 55:: Fugitivee Dust. Regulates fugitive dust emissions from any commercial construction or demolition activity capabl e of generating fugitive dust emissions, including active operations, open storage piles, and inactive disturbed areas, as well as track-out and carry-out onto paved roads beyond a project site (SDAPCD 2009).
x SDAPCDD Regulationn IV:: Prohibitions;; Rulee 67.0.1:: Architecturall Coatings. Requires manufacturers, distributors, and end users of architectural and industrial maintenance coatings to reduce VOC emissions from the use of these coatings, primarily by placing limits on the VOC content of various coating categories (SDAPCD 2015).
Cityy off Sann Marcoss
The City’s General Plan (City of San Marcos 2013) includes various policies related to reducing Air Quality and GHG emissions. Applicable policies include the following:
Landd Usee andd Communityy Designn Elementt
Policyy LU-2.1: Promote compact development patterns that reduce air pollution and automobile dependence and facilitate walking, bicycling, and transit use.
Policyy LU-3.1: Require that new development and redevelopment incorporate connections and reduce barriers between neighborhoods, transit corridors, and activity centers within the City.
Mobilityy Elementt
Policyy M-2.1: Work with new development to design roadways that minimize traffic volumes and/or speed, as appropriate within residential neighborhoods; while maintaining the City’s desire to provide connectivity on the roadway network.
2.3 Regional and Local Air Quality
2.3.1 San Diego Air Basin Attainment Designation
Pursuant to the 1990 Clean Air Act amendments, the EPA classifies air basins (or portions thereof) as “attainment” or “nonattainment” for each criteria air pollutant based on whether the NAAQS have been achieved.
Generally, if the recorded concentrations of a pollutant are lower than the standard, the area is classified as “attainment” for that pollutant. If an area exceeds the standard, the area is classified as “nonattainment” for that pollutant. As previously discussed, these standards are se t by the EPA or CARB for the maximum level of a given air pollutant that can exist in the outdoor air without unacceptable effects on human health or the public welfare.
If there is not enough data available to determine whether the standard is exceeded in an area, the area is
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT
13170
24 February 2023
designated as “unclassified” or “unclassifiable.” The designation of “unclassifiable/attainment” means that the area meets the standard or is expected to meet the standard despite a lack of monitoring data. Areas that achieve the standards after a nonattainment designation are re-designated as maintenance areas and must have approved maintenance plans to ensure continued attainment of the standards. The California Clean Air Act, like its federal counterpart, calls for the designation of area s as “attainment” or “nonattainment,” but based on the CAAQS rather than the NAAQS. The attainment classifications for the criteria pollutants are outlined in Table 2.

Attainment = meets the standards; attainment/maintenance = achieve the standards after a nonattainment designation; nonattainment = does not meet the standards; unclassified or unclassifiable = insufficient data to classify; unclassifiable/attainment = meets the standard or is expected to be meet the standard despite a lack of monitoring data.
a The federal 1-hour standard of 0.12 ppm was in effect from 1979 through June 15, 2005. The revoked standard is referenced here because it was employed for such a long period and because this benchmark is addressed in State Implementation Plans.
In summary, the SDAB is designated as a nonattainment area for the 2008 8-hour O 3 NAAQS. The SDAB is designated as a nonattainment area for O 3, PM10, and PM 2.5 CAAQS. The portion of the SDAB where the project site is located is designated as attainment or unclassifiable/unclassified for all other criteria pollutants under the NAAQS and CAAQS.
2.3.2 Local Ambient Air Quality
The SDAPCD operates a network of ambient air monitori ng stations throughout San Diego County that measure ambient concentrations of pollutants and determine whether the ambient air quality meets the CAAQS and the NAAQS. The SDAPCD monitors air quality conditions at 11 locations throughout the SDAB. Camp Pendleton monitoring station is the closest to the project site for O 3 and NO 2. The Escondido – East Valley Parkway monitoring station ceased to collect data post-2015; thus, due to proximity to the site and similar geographic and climactic characteristics, the San Diego – 11403 Rancho Carmel Drive monitoring station concentrations are considered most representative for the project site. Data for this station was available for CO. The El Cajon monitoring station was used for SO 2, PM10,a n d P M2.5. Ambient concentrations of pollutants from 2019 through

The El Cajon-Lexington Elementary School monitoring station is located at 533 First Street, El Cajon, California. a Measurements of PM 10 and PM 2.5 are usually collected every 6 days and every 1 to 3 days, respectively. Number of days exceeding the standards is a mathematical estimate of the numb er of days concentrations would have been greater than the level of the standard had each day been monitored. The numb ers in parentheses are the measured number of samples that exceeded the standard.
2.4 Significance Criteria and Methodology
2.4.1 Thresholds of Significance
Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) provides guidance for evaluating whether a development project may result in significant impacts. Based on Appendix G of the CEQA Guidelines, the project would have a significant impact on air quality if the project would:
1. Conflict with or obstruct implementation of the applicable air quality plan.
2. Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard.
3. Expose sensitive receptors to substantial pollutant concentrations.
4. Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.
Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) indicates that, where available, the significance criteria established by the applicable air quality management district or pollution control district may be relied upon to determine whether the project would have a significant impact on air quality. As part of its air quality permitting process, the SDAPCD has established thresholds in Rule 20.2 requiring the preparation of Air Quality Impact Assessments for permitted stationary sources. Th e SDAPCD sets forth quantitative emission thresholds below which a stationary source would not have a significant impact on ambient air quality. Project-related air quality impacts estimated in this environmental analysis would be considered significant if any of the applicable significance thresholds presented in Table 4 are exceeded.
For CEQA purposes, these screening criteria can be used as numeric methods to demonstrate that a project’s total emissions would not result in a significant impact to air quality.
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT
13170
27 February 2023
For nonattainment pollutants, if emissions exceed the thresholds shown in Table 4, the project could have the potential to result in a cumulatively considerable net increase in these pollutants and thus could have a significant impact on ambient air quality. A project that involves a use that would produce objectionable odors would be deemed to have a significant odor impact if it would affect a considerable number of off-site receptors.

2.4.2 Approach and Methodology
2.4.2.1 Construction
Construction assumptions, including timing, phasing, and equipment type and quantity, as well as worker and vendor truck trips, were based on information provided by the applicant. Default values provided by the California Emissions Estimator Model (CalEEMod) were used where detailed project information was not available. For purposes of estimating project GHG emissions, it is assumed that construction of the project would commence in June 20233 and would end in November 2024. Construction of the project is anticipated to occur in five phases.
Accordingly, five phases consisting of site preparation, grading, building construction, paving, and architectural 3 The analysis assumes a construction start date of June 2023, wh ich represents the earliest date construction would initiate (although unlikely). Assuming the earliest start date for construction represents the worst-case scenario for criteria air poll utant emissions because equipment and vehicle emission factors for later years would be slightly less due to more stringent standards for in-use off-road equipment and heavy-duty trucks, as well as fleet turnover replacing older equipment and vehicles in later years.

coating were assumed. The analysis contained herein is based on the following assumptions (the duration of phases is approximate):
x Site Preparation: 10 days (June 2023)
x Grading: 2 months (June 2023 – July 2023)
x Building Construction: 14 months (July 2023 – September 2024) x Paving: 1 month (September 2024 – October 2024)
x Architectural Coating: 1 month (October 2024 – November 2024) The construction equipment mix used for estimating construction emissions of the project is based on CalEEMod defaults and is shown in Table 5, Construction Scenario Assumptions – Proposed Project. For worker and vendor truck trips, the default CalEEMod assumptions for one-way trips were rounded up to the nearest even number to account for whole round trips. For this analysis, it was generally assumed that heavy construction equipment would operate 5 days a week (22 days per month) during project construction. Grading activities were anticipated to be minimal for the project; therefore, no haul trucks would be required to import or export material. VOC off- gassing emissions result from evaporation of solvents contained in surface coatings, such as in paints and primers used during the architectural coating phase. The VOC emissions factor is based on the VOC content of the surface coatings. SDAPCD’s Rule 67.0.1 (Architectural Coatings) governs the VOC content for interior and exterior coatings (SDAPCD 2015): internal reapplication architectural coatings would have a VOC content of 50 grams per liter (g/L), and exterior architectural coatings would have a VOC content of 100 g/L.

The project would implement dust control strategies. To reflect implementation of proposed dust control strategies, the following was assumed in CalEEMod in accordance with SDAPCD Rule 55:
x Water exposed area two times per day (55% reduction in PM10 and PM2.5). x Limit unpaved road travel to 15 miles per hour.
HHealthh Riskk Assessmentt
As a precautionary measure, a health risk assessment (HRA) was performed to assess the impact of construction on sensitive receptors proximate to the project. This report includes an HRA associated with emissions from construction of the project based on the methodologies pr escribed in the Office of Environmental Health Hazard Assessment (OEHHA) Air Toxics Hot Spots Program Risk Assessment Guidelines – Guidance Manual for Preparation of Health Risk Assessments (OEHHA 2015). To implement the OEHHA Guidel ines based on Project information, the SDAPCD has developed a three-tiered approach where each successive tier is progressively more refined, with fewer conservative assumptions. The SDAPCD Supplemental Guidelines for Submission of Air Toxics “Hot Spots” Program Health Risk Assessmentsprovides guidance with which to perform HRAs within the SDAB (SDAPCD 2022).
Health effects from carcinogenic air toxics are usually described in terms of cancer risk. The SDAPCD recommends a carcinogenic (cancer) risk threshold of 10 in a million. Additionally, some TACs increase non- cancer health risk due to long-term (chronic) exposures. The Chronic Hazard Index is the sum of the individual substance chronic hazard indices for all TACs affecting the same target organ system. The SDAPCD recommends a Chronic Hazard Index significance threshold of 1.0 (project increment). The exhaust from diesel engines is a complex mixture of gases, vapors, and particles, many of which are known human carcinogens. DPM has established cancer risk factors and relative exposure values for long-term chronic health hazard impacts. No short-term, acute relative exposure level has been established for DPM; therefore, acute impacts of DPM are not addressed in this assessment. This HRA evaluated the risk to future residents from diesel emissions from exhaust from onsite construction equipment and diesel haul and vendor trucks.
The dispersion modeling of DPM was performed using the American Meteorological Society/EPA Regulatory Model (AERMOD), which is the model SDAPCD requires for atmospheric dispersion of emissions. AERMOD is a steady-state Gaussian plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of surface and elevated sources, building downwash, and simple and complex terrain (EPA 2015). For the Project, AERMOD was run with all sources emitting unit emissions (1 gram per second) to obtain the “ Χ/Q” values. Χ/Q is a dispersion factor that is the average effluent concentration normalized by source strength and is used as a way to simplify the representation of emissions from many sources. The Χ/Q values of ground-level concentrations were determined for construction emissions using AERMOD and the maximum concentrations determined for the 1-hour and Period averaging periods. Principal parameters of this modeling are presented in Table 6.
Tablee 66 AERMOD Principall Parameters
Parameter Details
Meteorological Data The latest 3-year meteorological data (2010–2012) for the Escondido Station (Station ID 3177) from SDAPCD were downloaded and then input to AERMOD. For cancer or chronic noncancer risk assessments, the average cancer risk of all years modeled was used.

Urban versus Rural
Option
Urban areas typically have more surface roughness, as well as structures and low- albedo surfaces that absorb more sunlight—and thus more heat—relative to rural areas. However, based on the SDAPCD guidelines, the rural dispersion option was selected due to the Project’s proximity to the ocean.
Terrain
Characteristics
The terrain in the vicinity of the modeled Project site is generally flat. The elevation of the modeled site is about 545 feet above sea level. Digital elevation model files were imported into AERMOD so that complex terrain features were evaluated as appropriate.
Elevation Data Digital elevation data were imported into AERMOD, and elevations were assigned to the emission sources and receptors. Digital elevation data were obtained through AERMOD View in the United States Geological Survey’s National Elevation Dataset format with a 10-meter resolution.
Emission Sources
and Release
Parameters
Air dispersion modeling of DPM from construction equipment was conducted using emissions estimated using the CalEEMod, assuming emissions would occur 8 hours per day, 5 days per week. The Project area was modeled as a series of volume sources.
Source Release
Characterizations
Based on EPA methodology, the modeled line volume sources would result in a release height of 3.4 meters, a plume height of 6.8 meters, and a plume width of
8.6 meters for off-road equipment and diesel trucks (EPA 2015).
Discrete Receptors A uniform Cartesian grid overlaying residential receptors in close proximity to the project with 20-meter resolution was placed. Additional discrete receptors were placed over residences not within the uniform Cartesian grid.
NNote: See Appendix B.
Dispersion model plotfiles from AERMOD were then imported into CARB’s Hotspots Analysis and Reporting Program Version 2 to determine health risk, which requires peak 1-hour emission rates and annual-averaged emission rates for all pollutants for each modeling source. For the residential health risk, the HRA assumes exposure would start in the third trimester of pregnancy. The results of th e HRA are provided in Section 2.5, and detailed results and methodology are provided in Appendix B.
2.4.2.2 Operation
Emissions from the operational phase of the project was estimated using CalEEMod. Operational year 2024 was assumed because it would coincide with completion of construction.
Areaa Sourcess
The project would generate air quality emissions from area sources. Consumer products are chemically formulated products used by household and institutional consumers, including detergents; cleaning compounds; polishes; floor finishes; cosmetics; personal care products; home, lawn, and garden products; disinfectants; sanitizers; aerosol paints; and automotive specialty pr oducts. Other paint products, furniture coatings, or architectural coatings are not considered consumer products (CAPCOA 2021). The CalEEMod default values for consumer products were modeled.

VOC off-gassing emissions result from evaporation of solvents contained in surface coatings, such as in paints and primers used during building maintenance. CalEEMod calculates the VOC evaporative emissions from application of surface coatings based on the VOC emissions factor, the building square footage, the assumed fraction of surface area, and the reapplication rate. The VOC emissions factor is based on the VOC content of the surface coatings, and SDAPCD’s Rule 67.0.1 (Architectural Coatings) governs the VOC content for interior and exterior coatings (SDAPCD 2015). The model default reapplication rate of 10% of area per year is assumed.
Consistent with CalEEMod defaults, it was assumed that the surface area for painting equals 2.7 times the floor square footage, with 75% assumed for interior coating and 25% assumed for exterior surface coating (CAPCOA 2021). Consistent with the architectural coatings used during the construction phase, the applicant would use architectural coatings with a VOC content of 50 g/L for internal reapplication, and a VOC content of 100 g/L for exterior architectural coatings for any reapplication during operation.
Landscape maintenance includes fuel combustion emissions from equipment such as lawn mowers, rototillers, shredders/grinders, blowers, trimmers, chainsaws, and hedge trimmers. Emissions from landscape equipment use are estimated based on CalEEMod default values for emission factors (grams per square foot of nonresidential building space per day) and number of summer days (when landscape maintenance would generally be performed) and winter days. Emissions associated with potential landscape maintenance equipment were included to conservatively capture potential project operational emission sources.
No woodstoves or wood burning fireplaces would be included in the project design; therefore, they were not included in the CalEEMod analysis. The project would include natural gas fireplaces and are included in the CalEEMod analysis.
E
Energyy Sourcess
As represented in CalEEMod, energy sources would include emissions associated with building electricity and natural gas usage. Electricity use would contribute indire ctly to criteria air pollutant emissions; however, the emissions from electricity use are only quantified for GH Gs in CalEEMod, since criteria pollutant emissions occur at the site of the power plant, which is typically off site.
Operational criteria air pollutant emissions from energy sources include natural gas combustion for appliances and space and water heating. The current Title 24, Part 6 standards, referred to as the 2019 Title 24 Building Energy Efficiency Standards, became effective on January 1, 2020. CalEEMod defaults were assumed for electricity and natural gas.
Mobilee Sourcess
The project would generate air quality emissions from mo bile sources (vehicular traffic) as a result of the residents of the project. CalEEMod was used to estimate emissions from proposed vehicular sources (refer to Appendix A). The trip generation rates for the project residential land use were adjusted in CalEEMod to match the overall weekday daily trips based on the Traffic Impact An alysis (LLG 2021). CalEEMod default data, trip modes, trip lengths, fleet mix, and emissions factors were used for the model inputs. CalEEMod default vehicle emission factors and vehicle fleet mix for 2024, as based on the CARB EMFAC2017 model, were used to estimate emissions associated with vehicular sources.

2.5 Impact Analysis
TThresholdd 1:: Wouldd thee projectt conflictt withh orr obstructt implementationn off thee applicablee airr qualityy plan?? As mentioned in Section 2.2, Regulatory Setting, the SDAPCD is responsible for developing and implementing the clean air plans for attainment and maintenance of the ambient air quality standards in the SDAB—specifically, the SIP and RAQS.
4 SANDAG is responsible for developing forecasts and data that are used by the SDAPCD in preparing the SIP and RAQS. The federal O3 maintenance plan, which is part of the SIP, was adopted in 2012. The SIP includes a demonstration that current strategies and ta ctics will maintain acceptable air quality in the basin based on the NAAQS. The RAQS was initially adopted in 1991 and is updated every 3 years (most recently in 2020). The RAQS outlines SDAPCD’s plans and control measures designed to attain the state air quality standards for O 3. The SIP and RAQS rely on information from CARB and SANDAG, including mobile and area source emissions, as well as information regarding projec ted growth in the County as a whole and the cities in San Diego County, to project future emissions and determine the strategies necessary for the reduction of emissions through regulatory controls. CARB mobile source emission projections and SANDAG growth projections are based on population, vehicle trends, and land use plans developed by the County and the cities in the County as part of development of their general plans.
Although the SDAPCD and City do not provide guidance regarding the analysis of impacts associated with air quality plan conformance, the County’s Guidelines for Determining Significance and Report and Format and Content Requirements – Air Quality does discuss conformance with the RAQS (County of San Diego 2007). The guidance indicates that, if the project, in conjunction with other projects, contributes to growth projections that would not exceed SANDAG’s growth projections for a city, the project would not be in conflict with the RAQS. If a project includes development that is greater than that anticipated in the local plan and SANDAG’s growth projections, the project might be in conflict with the SIP and RAQS and may contribute to a potentially significant cumulative impact on air quality (County of San Diego 2007). The project’s proposed zoning is compared to the existing land use designation on the site and then the pr oject’s growth inducing impacts are compared to those included in the SANDAG’s growth projections for the City.
The project site is currently zoned Industrial (I) with a maximum floor-to-area ratio of 0.50. The floor-to-area ratio means the ratio of gross building area of th e development, excluding structured parking areas, proposed for the project divided by the net lot area. According to the City of San Ma rcos Municipal Code, the Industrial (I) land use zone is intended to “provide a setting for the full range of indoor manufacturing, distribution, warehousing, processing, and general service uses that are adequately served by vehicular arterials and utilities. Industries that use hazardous materials, require heavy equipment, and/or that generate sustained noise levels are deemed appropriate for this Zone, and may be permitted accordin g to the standards of this chapter. The I Zone is intended to implement and be consistent with the Industrial land use designation of the General Plan” (City of San Marcos 2020a).
The project proposes a GPA/Rezone to change the land use from an Industrial (I) to a SPA. This target density would net a maximum of 495 dwelling units. The City proj ects an increase of 3,170 housing units between 2020 and 2035 (SANDAG 2013), and the project would only account for 16% of the projected housing units to increase in the City between 2020 and 2035 in the SANDAG Series 13 forecast. The project’s proposed GPA/Rezone 4 For the purpose of this discussion, the relevant federal air quality plan is the Ozone Maintenance Plan (SDAPCD 2012). The RAQS is the applicable plan for purposes of state air quality planning. Both plans reflect growth projections in the SDAB.

would be within the growth projections for the City; thus, the project would result in regional growth that is accounted for within the RAQS. Furthermore, at a regional level, the growth is consistent with the underlying growth forecasts in the SIP and RAQS. Therefore, implementation of the proposed project would not conflict with the RAQS or SIP, and potential future development would be consistent with the growth in the region. The project’s proximity to State Route 78 and the Palomar College Sprinter station and bus station make for ideal connectivity to a regional transportation network, employment centers, and shopping and services. In addition, the project would implement applicable measures in the City’s 2020 CAP Consistency Checklist (see Appendix C), which would result in co-benefits to reducing the project’s operational air quality emissions by installing electric vehicle charging stations, installing bicycle infrastructure, implementing a Transportation Demand Management Plan, and reducing parking near transit. These measures would further reduce the project’s emissions from vehicle trips, increase access to transit, and encourage alternative modes of transportation. Impacts would be l
lesss thann significant..
Thresholdd 2:: Wouldd thee projectt resultt inn aa cumulativelyy considerablee nett increasee off anyy criteriaa pollutantt forr whichh thee projectt regionn iss nonattainmentt underr ann applicablee federall orr statee ambientt airr qualityy standardd (includingg releasingg emissionss whichh exceedd quantitativee thresholdss forr ozonee precursors)?? In analyzing cumulative impacts from a project, the analysis must specifically evaluate a project’s contribution to the cumulative increase in pollutants for which the air basin is designated as nonattainment for the CAAQS and NAAQS. If a project does not exceed thresholds and is determined to have less-than-significant project-specific impacts, it may still contribute to a significant cumulative impact on air quality if the emissions from the project, in combination with the emissions from other proposed or reasonably foreseeable future projects, are in excess of established thresholds. However, a project would only be considered to have a significant cumulative impact if the project’s contribution accounts for a significant proportion of the cumulative total emissions (i.e., it represents a “cumulatively considerable contribution” to the cumulative air quality impact).
Additionally, for the SDAB, the RAQS serves as the long-term regional air quality planning document for the purpose of assessing cumulative operational emissions to ensure that the SDAB continues to make progress toward NAAQS and CAAQS attainment status. As such, cumulative projects located in the San Diego region would have the potential to result in a cumulative impact to ai r quality if, in combination, they would conflict with or obstruct implementation of the RAQS. Similarly, individual projects that are inconsistent with the regional planning documents upon which the RAQS is based would have the potential to result in cumulative operational impacts if they represent development and population increases beyond regional projections.
The SDAB has been designated as a federal nonattainment area for O 3 and a state nonattainment area for O 3,
PM10, and PM2.5. PM10 and PM2.5 emissions associated with construction generally result in “near-field” impacts.
The nonattainment status is the result of cumulative emissions from all sources of these air pollutants and their precursors within the SDAB. Construction would be short term and temporary, and once construction is completed, construction-related emissions would cease. Operational emissions generated by the project would not exceed the significance thresholds for VOCs, NO
x, CO, SOx, PM10, or PM2.5, and would not cause a significant impact. As such, the project would result in less-than-significant impacts to air quality relative to operational emissions.
Construction of the project would result in the temporary addition of pollutants to the local airshed caused by soil disturbance, fugitive dust emissions, and combustion pollutants from on-site construction equipment, as well as from off-site trucks hauling construction materials. Construction emissions can vary substantially from day to day, depending
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT

on the level of activity, the specific type of operation, and for dust, the prevailing weather conditions. Therefore, such emissions levels can only be estimated, with a corresponding uncertainty in precise ambient air quality impacts.
Fugitive dust (PM10 and PM2.5) emissions would primarily result from grading and site preparation activities. NOx and CO emissions would primarily result from the use of construction equipment and motor vehicles.
Construction emissions were calculated using CalEEMod for the estimated worst-case day over the construction period associated with each phase and reported as the maximum daily emissions estimated during each year of construction (2023 and 2024). Construction schedule assumptions, including phase type, duration, and sequencing, were based on information provided by the applicant and is intended to represent a reasonable scenario based on the best information available. A detailed depiction of the construction schedule—including information regarding phasing, equipment used during each phase, haul trucks, vendor trucks, and worker vehicles—is included in Section 2.4.2.1, Construction, of this report. The information contained in Appendix A (CalEEMod Output Files) was used for the CalEEMod inputs.
Implementation of the project would generate temporary air pollutant emissions from entrained dust, off-road equipment, vehicle emissions, architectural coatings, an d asphalt pavement application. Entrained dust results from the exposure of earth surfaces to wind from the direct disturbance and movement of soil, resulting in PM 10 and PM2.5 emissions. The project is subject to SDAPCD Rule 55, Fugitive Dust Control. This rule requires that the project take steps to restrict visible emissions of fugitive dust beyond the property line. Compliance with Rule 55 would limit fugitive dust (PM 10 and PM2.5) that may be generated during grading and construction activities. To account for dust control measures in the calculations, it was assumed that the active sites would be watered at least two times daily, resulting in an approximately 55 % reduction of PM. Compliance with Rule 55 would be required as a standard condition of project approval or for issuance of a grading permit.
Exhaust from internal combustion engines used by construction equipment, hauling trucks (dump trucks), vendor trucks (delivery trucks), and worker vehicles would result in temporary emissions of NO x, VOC, CO, SOx, PM10, and
PM2.5. Application of architectural coatings, such as exterior/interior paint and other finishes, would also produce VOC emissions; however, the contractor is required to procure architectural coatings from a supplier in compliance with the requirements of SDAPCD Rule 67.0.1, Architectural Coatings. This rule requires manufacturers, distributors, and end users of architectural and industrial maintenance coatings to reduce VOC emissions from the use of these coatings, primarily by placing limits on the VOC content of various coating categories (SDAPCD 2015). The project would comply with SDAPCD Rule 67.0.1 through the incorporation of low- VOC architectural coatings. The VOC content assumed for the analysis was 50 g/L for interior coatings and 100 g/L for exterior coatings.
Table 7 shows the estimated maximum daily construction emissions associated with the construction of the project. Details of the emissions calculations are provided in Appendix A of this report.

The values shown are the maximum summer or winter daily emissions results from CalEEMod and provided in Appendix A. The maximum emissions assumes compliance with SDAPCD Rule 67.0.1, Architectural Coatings, and SDAPCD Rule 55, Fugitive Dust Control.
As shown in Table 7, daily construction emissions would not exceed the significance thresholds for NO x, CO, SOx, PM10, or PM2.5; however, the project would exceed the significance threshold for VOC.
Following completion of construction activities, the project would generate VOC, NO x, CO, SO x, PM10, and PM 2.5 emissions from mobile sources, including vehicular traffic generated by residents of the project; area sources, including the use of landscaping equipment and consumer products; and from architectural coatings.

As shown in Table 8, the daily operational emissions from the project would not exceed the significance thresholds for VOC, NOx, CO, SOx, PM10, or PM2.5.
Regarding long-term cumulative operational emissions in re lation to consistency with local air quality plans, the SIP and RAQS serve as the primary air quality planning documents for the state and SDAB, respectively. The SIP and RAQS rely on SANDAG growth projections based on population, vehicle trends, and land use plans developed by the cities and the County as part of development of th eir general plans. Development that is consistent with the growth anticipated by local plans would be consistent with the SIP and RAQS and would result in emissions that are accounted for. Projects that conform to the permitted land use, or result in a less emissions-intensive use, and are therefore accounted for in the SIP and RAQS an d would not be considered to result in cumulatively considerable impacts from operational emissions. As stated previously, the project would result in fewer vehicle miles traveled than buildout of the land use built under th e existing land use designation that was anticipated by the RAQS, and would be within the housing growth projections assumed in the SIP and RAQS; therefore, the project would not result in significant regional emissions that are not accounted for within the RAQS.

However, project construction would exceed the significance threshold for VOC. As a result, the potential for the project to result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable national or California ambient air quality standard is ppotentiallyy significant.
Thresholdd 3:: Wouldd thee projectt exposee sensitivee receptorss too substantiall pollutantt concentrations?? Air quality varies as a direct function of the amount of pollutants emitted into the atmosphere, the size and topography of the air basin, and the prevailing meteorological conditions. Air quality problems arise when the rate of pollutant emissions exceeds the rate of dispersion. Reduced visibility, eye irritation, and adverse health impacts on those persons termed “sensitive receptors” are the most serious hazards of existing air quality conditions in the area. Some land uses are considered more sensitive to changes in air quality than others, depending on the population groups and the activities involved. People most likely to be affected by air pollution, as identified by CARB, include children, older adults, athletes, and people with cardiovascular and chronic respiratory diseases; however, for the purposes of this analysis, residents are also considered sensitive receptors.
As such, sensitive receptors include residences, schools, pl aygrounds, childcare centers, athletic facilities, long- term healthcare facilities, rehabilitation centers, convalescent centers, and retirement homes.
Healthh Impactss off Toxicc Airr Contaminantss
In addition to impacts from criteria pollutants, project impacts may include emissions of pollutants identified by the state and federal government as TACs or hazardous air pollutants. State law has established the framework for California’s TAC identification and control program, which is generally more stringent than the federal program and aimed at TACs that are a problem in California. The state has formally identified more than 200 substances as TACs, including the federal hazardous air pollutants, and is adopting appropriate control measures for sources of these TACs. The greatest potential for TAC emissions du ring construction would be diesel particulate emissions from heavy-duty equipment operations and heavy-duty trucks, and the associated health impacts to sensitive receptors. The following measures are required by state law to reduce diesel particulate emissions:
x Fleet owners of mobile construction equipment are subject to the CARB Regulation for In-use Off-road Diesel Vehicles (Title 13 California Code of Regulations, Chapter 9, Section 2449), the purpose of which is to reduce DPM and criteria pollutant emissions from in-use (existing) off-road diesel-fueled vehicles. x All commercial diesel vehicles are subject to Title 13, Section 2485 of the California Code of Regulations, limiting engine idling time. Idling of heavy-duty diesel construction equipment and trucks during loading and unloading shall be limited to 5 minutes; electric auxiliary power units should be used whenever possible.
The greatest potential for TAC emissions during construction would be DPM emissions from heavy-duty equipment operations and heavy-duty trucks during construction of the project and the associated health impacts to sensitive receptors.
However, as a precautionary measure, an HRA was performed to evaluate the risk from diesel exhaust emissions on existing sensitive receptors and future onsite receptors from construction activities. The HRA methodology was described in Section 2.4.2.1, and the detailed assessment is provided in Appendix B. Table 9 summarizes the results of the HRA for proposed project construction.

The results of the HRA demonstrate that the TAC exposure from construction diesel exhaust emissions would result in cancer risk on site below the 10 in 1 million threshold, as well as Chronic Hazard Index less than 1.0. Therefore, TAC emissions from construction of the proposed project would not expose sensitive receptors to substantial pollutant concentrations and would result in a l

Healthh Impactss off Carbonn Monoxidee
As described previously, exposure to high concentrations of CO can result in dizziness, fatigue, chest pain, headaches, and impairment of central nervous system functions. Mobile-source impacts, including those related to CO, occur essentially on two scales of motion. Regionally, project-related construction travel would add to regional trip generation and increase the vehicle miles traveled within the local airshed and the SDAB. Locally, construction traffic would be added to the roadway system in the vicinity of the project site. Although the SDAB is currently an attainment area for CO, there is a potential for the formation of microscale CO “hotspots” to occur immediately around points of congested traffic. Hotspots can form if such traffic occurs during periods of poor atmospheric ventilation, is composed of a large number of vehicles cold-started and operating at pollution- inefficient speeds, and/or is operating on roadways already crowded with non-project traffic. Because of continued improvement in vehicular emissions at a rate faster than the rate of vehicle growth and/or congestion, the potential for CO hotspots in the SDAB is steadily decreasing.
The Governor’s Office of Planning and Research and the California Natural Resources Agency have issued new CEQA Guidelines for analyzing transportation impacts. By July 1, 2020, all CEQA lead agencies must analyze a project’s transportation impacts using vehicle-miles traveled. Vehicle-miles traveled measures the distances vehicles will travel to and from a project, rather than congestion levels at intersections (LOS, graded on a scale of A–F). To account for this shift from LOS to vehicle-miles traveled, and evaluate the potential for CO hotspots for the project, analysis performed by SCAQMD is leveraged as follows.
The SDAB is a CO maintenance area (western and central part of the SDAB only). As a screening analysis, the SCAQMD conducted CO modeling for the 2003 Air Quality Management Plan (Appendix V of SCAQMD 2003) for the four worst-case intersections in the South Coast Air Basin: (1) Wilshire Boulevard and Veteran Avenue, (2) Sunset Boulevard and Highland Avenue, (3) La Cienega Boulevard and Century Boulevard, and (4) Long Beach Boulevard and Imperial Highway. At the time the 2003 Air Quality Management Plan was prepared, the intersection of Wilshire Boulevard and Veteran Avenue was the most congested intersection in Los Angeles County, with an average daily traffic volume of about 10 0,000 vehicles per day. Using CO emission factors for 2002, the peak modeled CO 1-hour concentration was esti mated to be 4.6 ppm at the intersection of Wilshire Boulevard and Veteran Avenue.

For potential future development associated with approval of the proposed project, the daily traffic volume of 100,000 vehicles would be conservative compared to the traffic volumes of nearby intersections. When added to the maximum 1-hour CO concentration from 2019 through 2021 at the San Diego – 11403 Rancho Carmel Drive monitoring station (see Table 3, Local Ambient Air Quality Data), which was 4.1 ppm in 2019, the 1-hour CO would be 8.7 ppm, while the CAAQS is 20 ppm.
The SCAQMD modeled future year 8-hour CO concentrations at the Central Los Angeles monitoring site of 4.6 ppm in 2020. Adding the 4.6 ppm to the maximum 8-hour CO concentration from 2019 through 2021 at the San Diego – 11403 Rancho Carmel Drive monitoring station (s ee Table 3, Local Ambient Air Quality Data), which was
2.5 ppm in 2019, the 8-hour CO would be 7.1 ppm, while the CAAQS is 9.0 ppm.
Accordingly, CO concentrations at congested intersecti ons would not exceed the 1-hour or 8-hour CO CAAQS unless projected daily traffic would exceed 100,000 vehicles per day. Potential future development at the proposed project site would not increase daily traffic volumes at any study intersection to more than 100,000 vehicles per day (LLG 2022).
5 Therefore, it is concluded that the project traffic is not anticipated to create a CO hotspot, as emissions would be dispersed rapidly and would not be concentrated, and therefore no CO hotspots would be created. As such, impacts to sensitive receptors with regard to potential CO hotspots resulting from the project’s contribution to cumulative traffic-related air quality impacts would be llesss thann significant.
Healthh Impactss off Criteriaa Airr Pollutantss
Construction of the project would result in emissions that exceed the threshold for VOC without mitigation; however, project construction would not exceed significance thresholds for NO x, CO, SO x, PM10, or PM2.5. Project
operation would not exceed significance thresholds for VOC, NO x, CO, SO x, PM 10, or PM 2.5. VOCs and NO x are precursors to O3, for which the SDAB is designated as nonattainment with respect to the NAAQS and CAAQS (the SDAB is designated by the EPA as an attainment area for the 1-hour O 3 NAAQS standard). The health effects associated with O 3 are generally associated with reduced lung function. The contribution of VOCs and NO x to regional ambient O3 concentrations is the result of complex photochemistry. The increases in O3 concentrations in the SDAB due to O3 precursor emissions tend to be found downwind from the source location to allow time for the photochemical reactions to occur. However, the potential for exacerbating excessive O 3 concentrations also depends on the time of year that the VOC emissions occur because exceedances of the O3 CAAQS/NAAQS tend to occur between April and October when solar radiation is highest. The holistic effect of a single project’s emissions of O
3 precursors is speculative due to the lack of quantitative methods to assess this impact. Operation of the project would not exceed the significance threshold for NO x; therefore, implementation of the project would contribute minimally to regional O 3 concentrations and the associated health effects. Although emission reductions from the following project design features were not quantified, the project would install electric vehicle charging stations, install bicycle infrastructure, implement Transportation Demand Management Plan, install electric or solar water heaters that would result in co-ben efits of reducing the project’s operational emissions of VOC and NOx. However, due to exceedances in construction-generated emissions of VOC, the project could result in potential health effects associated with VOCs.
Operation of the project would not contribute to exceedances of the NAAQS or CAAQS for NO 2. As discussed above, the project would implement required CAP Checklist items that would result in co-benefits of reducing the 5 For each study intersection in each scenario evaluated in the Traffic Impact Analysis, all 10 study intersections were estimate d to result in less than 100,000 vehicles per day in every scenario evaluated (ranging from 4,649 vehicles to 44,977 vehicles).

project’s operational emissions of VOC and NOx. Health effects that result from NO 2 and NOx include respiratory irritation, which could be experienced by nearby recept ors during the periods of heaviest use of off-road construction equipment. However, project construction would be relatively short term, and off-road construction equipment would be operating at various portions of the site and would not be concentrated in one portion of the site at any one time. In addition, existing NO
2 concentrations in the area are well below the NAAQS and CAAQS standards. Because project-generated NO x emissions would not exceed the significance threshold, the project would not result in potential health effects associated with NO2 and NOx.
CO tends to be a localized impact associated with co ngested intersections. The associated potential for CO hotspots are discussed above and were determined to be a less-than-significant impact. Furthermore, the existing CO concentrations in the area are well below the NAAQS and CAAQS standards. Thus, the project’s CO emissions would not contribute to significant health effects associated with this pollutant.
Construction and operation of the project would also not exceed thresholds for PM 10 or PM 2.5, and would not contribute to exceedances of the NAAQS or CAAQS for PM or obstruct the SDAB from coming into attainment for these pollutants. The project would also not result in substantial DPM emissions during construction or operation, and therefore, would not result in significant health effects related to DPM exposure. Additionally, the project would implement dust control strategies and be required to comply with SDAPCD Rule 55, Fugitive Dust, which limits the amount of fugitive dust generated during co nstruction. Due to the minimal contribution of PM during construction and operation, the project is not anticipated to result in health effects associated with PM 10 or PM2.5.
In summary, because operation of the project would not result in exceedances of the SDAPCD significance thresholds, the potential health effects associated with criteria air pollutants would be less than significant.
Furthermore, there are numerous scientific and technologica l complexities associated with correlating criteria air pollutant emissions from an individual project to specific health effects or potential additional nonattainment days, and there are currently no modeling tools that could provide reliable and meaningful additional information regarding health effects from criteria air pollutants generated by individual projects within the SDAPCD’s jurisdiction.
The California Supreme Court’s Sierra Club v. County of Fresno (2018) 6 Cal. 5th 502 decision (referred to herein as the Friant Ranch decision) (issued on December 24, 2018) addresses the need to correlate mass emission values for criteria air pollutants to specific health co nsequences, and contains the following direction from the California Supreme Court: “The Environmental Impact Repo rt (EIR) must provide an adequate analysis to inform the public how its bare numbers translate to create potential adverse impacts or it must explain what the agency does know and why, given existing scientific constraints, it cannot translate potential health impacts further” (italics original). Currently, the SDAPCD, CARB, and EPA have not approved a quantitative method to reliably, meaningfully, and consistently translate the mass emissions estimates for the criteria air pollutants resulting from a project to specific health effects. In addition, there are numerous scientific and technological complexities associated with correlating criteria air pollutant emissions from an individual project to specific health effects or potential additional nonattainment days.
In connection with the judicial proceedings culminating in issuance of the Friant Ranch decision, the South Coast Air Quality Management District (SCAQMD) and San Joaquin Valley Air Pollution Control District (SJVAPCD) filed amicus briefs attesting to the extreme difficulty of correlating an individual project’s criteria air pollutant emissions to specific health impacts. Both SJVAPCD and SCAQMD have among the most sophisticated air quality

modeling and health impact evaluation capabilities of the air districts in California. The key, relevant points from SCAQMD and SJVAPCD briefs are summarized below.
In requiring a health impact type of analysis for criteria air pollutants, it is important to understand how O3 and PM are formed, dispersed, and regulated. The formation of O 3 and PM in the atmosphere, as secondary pollutants, 6 involves complex chemical and physical interactions of multiple pollutants from natural and anthropogenic sources. The O 3 reaction is self-perpetuating (or catalytic) in the presence of sunlight because NO 2 is photochemically reformed from nitric oxide (NO). In this way, O3 is controlled by both NOx and VOC emissions. The complexity of these interacting cycles of pollutants means that incremental decreases in one emission may not result in proportional decreases in O3 (NRC 2005). Although these reactions and interactions are well understood, variability in emission source operations and meteorology creates uncertainty in the modeled O 3 concentrations to which downwind populations may be exposed (NRC 2005). Once formed, O3 can be transported long distances by wind, and due to atmospheric transport, contributions of precursors from the surrounding region can also be important (EPA 2008). Because of the complexity of O 3 formation, a specific tonnage of VOCs or NOX emitted in a particular area does not equate to a particular concentration of O 3 in that area (SJVAPCD 2015). PM can be divided into two categories: directly emitted PM and secondary PM. Secondary PM, like O 3, is formed via complex chemical reactions in the atmosphere between precursor chemicals such as SO x and NO x. Because of the complexity of secondary PM formation, including the potential to be transported long distances by wind, the tonnage of PM-forming precursor emissions in an area does not necessarily result in an equivalent concentration of secondary PM in that area (SJVAPCD 2015). This is especially true for individual projects, where project- generated criteria air pollutant emissions are not derived from a single “point source” but from construction equipment and mobile sources (passenger cars and trucks) driving to, from, and around the project site.
Another important technical nuance is that health effects from air pollutants are related to the concentration of the air pollutant that an individual is exposed to, not necessarily the individual mass quantity of emissions associated with an individual project. For example, health effects from O 3 are correlated with increases in the
ambient level of O3 in the air a person breathes (SCAQMD 2015). However, it takes a large amount of additional precursor emissions to cause a modeled increase in ambient O3 levels over an entire region (SCAQMD 2015). The lack of link between the tonnage of precursor pollutants and the concentration of O 3 and PM 2.5 formed is important because it is not necessarily the tonnage of precursor pollutants that causes human health effects; rather, it is the concentration of resulting O
3 that causes these effects (SJVAPCD 2015). Indeed, the ambient air quality standards, which are statutorily required to be set by the EPA at levels that are requisite to protect the public health, are established as concentrations of O3 and PM2.5 and not as tonnages of their precursor pollutants (EPA 2018a). Because the ambient air quality standard s are focused on achieving a particular concentration region-wide, the tools and plans for attaining the ambient air quality standards are regional in nature. For CEQA analyses, project-generated emissions are typically estimated in pounds per day or tons per year and compared to mass daily or annual emission thresholds. Although CEQA thresholds are established at levels that the air basin can accommodate without affecting the attainment date for the Ambient Air Quality Standards, even if a project exceeds established CEQA significance thresholds, this does not mean that the concentration of O 3 or PM that will
be created at or near the project site on a particular day or month of the year, or what specific health impacts will occur, can easily be determined (SJVAPCD 2015).
6 Air pollutants formed through chemical reactions in the atmosphere are referred to as secondary pollutants.

In regard to regional concentrations and air basin at tainment, the SJVAPCD emphasized that attempting to identify a change in background pollutant concentrations that can be attributed to a single project, even one as large as the entire Friant Ranch Specific Plan, is a theoretical exercise. The SJVAPCD brief noted that it “would be extremely difficult to model the impact on NAAQS attainment that the emissions from the Friant Ranch project may have” (SJVAPCD 2015). The situation is further compli cated by the fact that background concentrations of regional pollutants are not uniform either temporally or geographically throughout an air basin, but are constantly fluctuating based on meteorology and other environmental factors. The SJVAPCD noted that the currently available modeling tools are equipped to model the impact of all emission sources in the San Joaquin Valley Air Basin on attainment (SJVAPCD 2015). The SJVAPCD brief then indicated that, “Running the photochemical grid model used for predicting O
3 attainment with the emissions solely from the Friant Ranch project (which equate to less than one-tenth of one percent of the total NO x and VOC in the Valley) is not li kely to yield valid information given the relative scale involved” (SJVAPCD 2015).
The SCAQMD and SJVAPCD have indicated that it is not feasible to quantify project-level health impacts based on existing modeling (SCAQMD 2015; SJVAPCD 2015). Even if a metric could be calculated, it would not be reliable because the models are equipped to model the impact of all emission sources in an air basin on attainment and would likely not yield valid information or a measurable increase in O 3 concentrations sufficient to accurately quantify O3-related health impacts from an individual project.
Nonetheless, following the Supreme Court’s Friant Ranch decision, some Environmental Impact Reports where estimated criteria air pollutant emissions exceeded applicable air district thresholds have included a quantitative analysis of potential project-generated health effects using a combination of a regional photochemical grid model (PGM)7 and the EPA’s Benefits Mapping and Analysis Program (BenMAP or BenMAP–Community Edition [CE]). 8 The publicly available health impact assessments (HIAs) typically present results in terms of an increase in health incidences and/or the increase in background health incidence for various health outcomes resulting from a project’s estimated increase in concentrations of O3 and PM2.5.9 The five publicly available HIAs have concluded that the evaluated project’s health effects associated with the estimated project-generated increase in concentrations of O
3 and PM2.5 represent a small increase in incidences and a very small percent of the number of background incidences, indicating that these health impacts are negligible and potentially within the model’s margin of error. In addition, the results of the five HIAs concluded that project emissions would not result in a substantial increase in health incidences, and the estimated emissions and assumed toxicity were also conservatively inputted into the HIA and, thus, overestimated health incidences, particularly for PM
2.5. 7 The first step in the publicly available health impact assessme nt is running a regional photochemical grid model (PGM), such as the Community Multiscale Air Quality (CMAQ) model or the Comprehensive Air Quality Model with extensions (CAMx), to estimate the increase in concentrations of O3 and PM2.5 as a result of project-generated emissions of criteria and precursor pollutants. Air districts, such as the SCAQMD, use photochemical air quality models for regional air qualit y planning. These photochemical models are large-scale air quality models that simulate the changes of pollutant concentrations in the atmosphere using a set of mathematical equations characterizing the chemical and physical processes in the atmosphere (EPA 2017a). 8 After estimating the increase in concentrations of O 3 and PM 2.5, the second step in the five examples is use of BenMAP or BenMAP-CE to estimate the resulting associated health effects. BenMAP estimates the number of health incidences resulting from changes in air pollution concentrati ons (EPA 2018b). The health impact functi on in BenMAP-CE incorporates four key sources of data: modeled or monitored air quality changes, popula tion, baseline incidence rates, and an effect estimate. All of the five example health impact assessments focused on O3 and PM2.5. 9 The following CEQA documents included a quantitative health impact assessment to address Friant Ranch: California State University Dominguez Hills 2018 Campus Master Plan EIR (CSU Dominguez Hills 2019), March Joint Powers Association K4 Warehouse and Cactus Channel Improvements EIR (March JP A 2019), Mineta San Jose Airport Amendment to the Airport Master Plan EIR (City of San Jose 2019), City of Inglewood Bask etball and Entertainment Center Project EIR (City of Inglewood 2019), and San Diego State University Mission Valley Campus Master Plan EIR (SDSU 2019).

As explained in the SJVAPCD brief (SJVAPCD 2015) and noted previously, running the PGM used for predicting O 3 attainment with the emissions solely from an individual project, like the Friant Ranch project or the proposed project, is not likely to yield valid information given the relative scale involved. The five examples reviewed support the SJVAPCD’s brief contention that consistent, reliable, and meaningful results may not be provided by methods applied at this time. Accordingly, additional work in the industry, and more importantly, air district participation, is needed to develop a more meaningful analysis to correlate project-level mass criteria air pollutant emissions and health effects for decision makers and the public. Furtherm ore, at the time of writing, no HIA has concluded that health effects estimated using the PGM and BenMAP approach are substantial, provided that the estimated project-generated incidences represent a very small percent of the number of background incidences, potentially within the model’s margin of error.
In summary, because construction of the project could result in exceedances of the significance thresholds for VOC, the potential health effects associated with criteria air pollutants, specifically O 3, would be p potentiallyy significant. Notably, there are numerous scientific and technological complexities associated with correlating criteria air pollutant emissions from an individual project to specific health effects or potential additional nonattainment days, and there are currently no modeling tools that could provide reliable and meaningful additional information regarding health effects from criteria air pollutants generated by individual projects.
Valleyy Feverr Exposuree
As discussed in Section 2.1.4, Pollutants and Effects, Valley Fever is not highly endemic to San Diego County, and within San Diego County, the incidence rate in the project area is below the County and statewide average.
Construction of the project would comply with SDAPCD Rule 55, which limits the amount of fugitive dust generated during construction. Strategies the project would implement to comply with SDAPCD Rule 55 and control dust include watering two times per day and limiting speed on unpaved roads to 15 miles per hour.
Based on the low incidence rate of Coccidioidomycosis in San Diego County and the project’s implementation of dust control strategies, it is not anticipated that earth-moving activities during project construction would result in exposure of nearby sensitive receptors to Valley Fever. Therefore, the project would have a l less-than-significant
impact with respect to Valley Fever exposure for sensitive receptors.
Thresholdd 4:: Wouldd thee projectt resultt inn otherr emissionss (suchh ass thosee leadingg too odors)) adverselyy affectingg aa substantiall numberr off people??
Odors would be generated from vehicle and equipment exhaust emissions during construction of the project.
Odors produced during construction would be attributable to concentrations of unburned hydrocarbons from tailpipes of construction equipment and from architectural coatings. Such odors would disperse rapidly from the project site and generally occur at magnitudes that woul d not affect substantial numbers of people. Therefore, impacts associated with odors during construction would be l lesss thann significant.
Land uses and industrial operations associated with odor complaints include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding (CARB 2005). The project would not engage in any of these activities. Moreover, typical odors generated from operation of the project would primarily include vehicle exhaust generated by residents and through the periodic use of landscaping and maintenance equipment. Th erefore, the project would result in an odor impact that is llesss thann significant.

2.6 Mitigation Measures
Mitigation Measure (MMM-)AQ-11 would be implemented to reduce VOC emissions generated during construction of the project.
MM-AQ-1 Architecturall Coatings. The project shall use low volatile organic compound (VOC) architectural coatings for interior application that do not exceed VOC content of 10 grams per liter, for exterior application that do not exceed VOC content of 50 grams per liter, and for parking application do not exceed VOC content of 100 grams per liter.
For Threshold 2 (Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an appl icable federal or state ambient air quality standard), Table 10 shows the estimated maximum daily construction em issions associated with construction of the project with implementation of MM-AQ-1.

See Appendix A for output files and modeling details.
The values shown are the maximu m summer or winter daily emissions results from CalEEMod and provided in Appendix A. The maximum emissions assumes compliance with SDAPCD Rule 55, Fugitive Dust Control and implementation of MM-AQ-1, use of low- VOC architectural coatings.
As shown in Table 10, daily construction emissions would not exceed the significance thresholds for VOC, NO x, CO, SO x, PM 10, or PM 2.5. Therefore, the potential for the project to result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable national or California ambient air quality standard, and health effects of criteria air pollutants would be reduced to a l lesss thann significantt impactt withh mitigation.

3 Greenhouse Gas Emissions
3.1 Environmental Setting
3.1.1 Climate Change Overview
Climate change refers to any significant change in measur es of climate, such as temperature, precipitation, or wind patterns, lasting for an extended period of time (decades or longer). The Earth’s temperature depends on the balance between energy entering and leaving the planet’s system. Many factors, both natural and human, can cause changes in Earth’s energy balance, including variations in the sun’s energy reaching Earth, changes in the reflectivity of Earth’s atmosphere and surface, and changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere (EPA 2017b).
The greenhouse effect is the trapping and build-up of heat in the atmosphere (troposphere) near the Earth’s surface. The greenhouse effect traps heat in the troposphere through a threefold process: short-wave radiation emitted by the Sun is absorbed by the Earth; the Earth emits a portion of this energy in the form of long-wave radiation; and GHGs in the upper atmosphere absorb this long-wave radiation and emit it into space and toward the Earth. The greenhouse effect is a natural process th at contributes to regulating the Earth’s temperature and creates a pleasant, livable environment on the Earth. Human activities that emit additional GHGs to the atmosphere increase the amount of infrared radiation that gets absorbed before escaping into space, thus enhancing the greenhouse effect and causing the Earth’s surface temperature to rise.
The scientific record of the Earth’s climate shows that the climate system varies naturally over a wide range of time scales, and that in general, climate changes prior to the Industrial Revolution in the 1700s can be explained by natural causes, such as changes in solar energy , volcanic eruptions, and natural changes in GHG concentrations. Recent climate changes, in particular th e warming observed over the past century, however, cannot be explained by natural causes alone. Rather, it is extremely likely that human activities have been the dominant cause of that warming since the mid-twentieth century and is the most significant driver of observed climate change (EPA 2017b; IPCC 2013). Human influence on the climate system is evident from the increasing GHG concentrations in the atmosphere, positive radiative forcing, observed warming, and improved understanding of the climate system (IPCC 2013). The atmospheric concentrations of GHGs have increased to levels unprecedented in the last 800,000 years, primar ily from fossil fuel emissions and secondarily from emissions associated with land use changes (IPCC 2013). Continued emissions of GHGs will cause further warming and changes in all components of the climate system, which is discussed further in Section 3.1.5, Potential Effects of Climate Change.
3.1.2 Greenhouse Gases and other Climate Forcing Substances A GHG is any gas that absorbs infrared radiation in the atmosphere; in other words, GHGs trap heat in the atmosphere. GHGs include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O), O 3, water vapor, hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs ), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).10 Some GHGs, such as CO 2, CH 4, and N 2O, occur naturally and are emitted to the atmosphere through natural processes and human activities. Of these gases, CO 2 and CH4 are emitted in the greatest quantities from 10 California Health and Safety Code Section 38505 identifies seven GHGs that CARB is responsible for monitoring and regulating to reduce emissions: CO2, CH4, N2O, SF6, HFCs, PFCs, and nitrogen trifluoride (NF3).

human activities. Manufactured GHGs, which have a much greater heat-absorption potential than CO 2, include fluorinated gases, such as HFCs, HCFCs, PFCs, and SF6, which are associated with certain industrial products and processes. A summary of the most common GHGs and their sources is included in the following text. 11 Also included is a discussion of other climate-forcing substances.
CCarbonn Dioxide.. CO2 is a naturally occurring gas and a by-product of human activities, and is the principal anthropogenic GHG that affects the Earth’s radiative balance. Natural sources of CO 2 include respiration of bacteria, plants, animals, and fungus; evaporation from oceans; volcanic out-gassing; and decomposition of dead organic matter. Human activities that generate CO
2 are the combustion of fuels such as coal, oil, natural gas, and wood, and changes in land use.
Methane.. CH4 is produced through both natural and human activities. CH 4 is a flammable gas and is the main component of natural gas. CH 4 is produced through anaerobic (without oxygen) decomposition of waste in landfills, flooded rice fields, animal digestion, decomposition of animal waste, production and distribution of natural gas and petroleum, coal production, and incomplete fossil fuel combustion.
Nitrouss Oxide.. N2O is produced through natural and human activities, mainly through agricultural activities and natural biological processes, although fuel burning and other processes also create N 2O. Sources of N 2O include soil cultivation practices (microbial processes in soil and water), especially the use of commercial and organic fertilizers, manure management, industrial processes (such as in nitric acid production, nylon production, and fossil-fuel-fired power plants), vehicle emissions, and using N2O as a propellant (such as in rockets, racecars, and aerosol sprays).
Fluorinatedd Gases.. Fluorinated gases (also referred to as F-gases) are powerful synthetic GHGs emitted from many industrial processes. Fluorinated gases are commonly used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons [CFCs], HCFCs, and halons). The most prevalent fluorinated gases are the following:
x Hydrofluorocarbons: HFCs are compounds containing only hydrogen, fluorine, and carbon atoms. HFCs are synthetic chemicals used as alternatives to ozone-depleting substances in serving many industrial, commercial, and personal needs. HFCs are emitted as by-products of industrial processes and are used in manufacturing.
x
Perfluorocarbons: PFCs are a group of human-made chemicals composed of carbon and fluorine only.
These chemicals were introduced as alternatives, with HFCs, to the ozone-depleting substances. The two main sources of PFCs are primary aluminum production and semiconductor manufacturing. Since PFCs have stable molecular structures and do not break down through the chemical processes in the lower atmosphere, these chemicals have long lifetimes, ranging between 10,000 and 50,000 years. x
Sulfurr Hexafluoride: SF6 is a colorless gas soluble in alcohol and ether and slightly soluble in water. SF6 is used for insulation in electric power transmission and distribution equipment, semiconductor manufacturing, the magnesium industry, and as a tracer gas for leak detection. x Nitrogenn Trifluoride: Nitrogen trifluoride (NF 3) is used in the manufacture of a variety of electronics, including semiconductors and flat panel displays.
11 The descriptions of GHGs are summarized from the Intergovernm ental Panel on Climate Change (IPCC) Second Assessment Report (IPCC 1995), IPCC Fourth Assessment Report (IPCC 2007), CARB’s Glossary of Terms Used in GHG Inventories (CARB 2015a), and EPA’s Glossary of Climate Change Terms (EPA 2016d).

CChlorofluorocarbons.. CFCs are synthetic chemicals that have been used as cleaning solvents, refrigerants, and aerosol propellants. CFCs are chemically unreactive in the lower atmosphere (troposphere), and the production of CFCs was prohibited beginning in 1987 due to the chemical destruction of stratospheric O
3. Hydrochlorofluorocarbons. HCFCs are a large group of compounds whose structure is very close to that of CFCs— containing hydrogen, fluorine, chlorine, and carbon atoms— but including one or more hydrogen atoms. Like HFCs, HCFCs are used in refrigerants and propellants. HCFCs we re also used in place of CFCs for some applications; however, their use is being phased out.
Blackk Carbon.. Black carbon is a component of fine particulate matter, which has been identified as a leading environmental risk factor for premature death. It is prod uced from the incomplete combustion of fossil fuels and biomass burning, particularly from older diesel engines and wildfires. Black carbon warms the atmosphere by absorbing solar radiation, influences cloud formation, and darkens the surface of snow and ice, which accelerates heat absorption and melting. Black carbon is a short-lived species that varies spatially, which makes it difficult to quantify its global warming potential. DPM emissions are a major source of black carbon and are TACs that have been regulated and controlled in California for several decades to protect public health. In relation to declining DPM from CARB’s regulations pertaining to diesel engines, diesel fuels, and burning activities, CARB estimates that annual black carbon emissions in California have been reduced by 70% between 1990 and 2010, with 95% control expected by 2020 (CARB 2014).
Waterr Vapor.. The primary source of water vapor is evaporation from the ocean, with additional vapor generated by sublimation (change from solid to gas) from ice and snow, evaporation from other water bodies, and transpiration from plant leaves. Water vapor is the most important, abundant, and variable GHG in the atmosphere and maintains a climate necessary for life.
Ozone.. Tropospheric O3, which is created by photochemical reactions involving gases from natural sources and human activities, acts as a GHG. Stratospheric O 3, which is created by the interaction between solar ultraviolet radiation and molecular oxygen (O 2), plays a decisive role in the stratospheric radiative balance. Depletion of stratospheric O3, due to chemical reactions that may be enhanced by climate change, results in an increased ground-level flux of ultraviolet-B radiation.
Aerosols.. Aerosols are suspensions of PM in a gas emitted into the air through burning biomass (plant material) and fossil fuels. Aerosols can warm the atmosphere by absorbing and emitting heat, and can cool the atmosphere by reflecting light.
3.1.3 Global Warming Potential
Gases in the atmosphere can contribute to climate change both directly and indirectly. Direct effects occur when the gas itself absorbs radiation. Indirect radiative forcing occurs when chemical transformations of the substance produce other GHGs, when a gas influences the atmospheric lifetimes of other gases, and/or when a gas affects atmospheric processes that alter the radiative balance of the Earth (e.g., affect cloud formation or albedo) (EPA 2017c). The Intergovernmental Panel on Climate Change (IPCC) developed the global warming potential (GWP) concept to compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP of a GHG is defined as the ratio of the time-integrated radiative forcing from the instantaneous release of 1 kilogram of a trace substance relative to that of 1 kilogram of a reference gas (IPCC 2014). The reference gas used is CO 2;
therefore, GWP-weighted emissions are measured in metric tons (MT) of carbon dioxide equivalent (CO2e).

The current version of CalEEMod (Version 2020.4.0) assumes that the GWP for CH 4 is 25 (so emissions of 1 MT of CH4 are equivalent to emissions of 25 MT of CO 2), and the GWP for N 2O is 298, based on the IPCC Fourth Assessment Report (IPCC 2007).
3.1.4 Sources of Greenhouse Gas Emissions
Anthropogenic GHG emissions worldwide in 2017 (the most recent year for which data is available) totaled approximately 50,860 million metric tons (MMT) of CO
2e, excluding land use change and forestry (PBL 2018). Six countries—China, the United States, the Russian Federation, India, Japan, and Brazil—and the European community accounted for approximately 65% of the total global emissions, or approximately 33,290 MMT CO 2e (PBL 2018).
Per the EPA Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2018, total United States GHG emissions were approximately 6,676.6 MMT CO 2e in 2018 (EPA 2020a). The primary GHG emitted by human activities in the United States was CO 2, which represented approximately 81.3% of total GHG emissions (5,428.1 MMT CO 2e). The largest source of CO 2, and of overall GHG emissions, was fossil-fuel combustion, which accounted for approximately 92.8% of CO 2 emissions in 2018 (5,031.8 MMT CO 2e). Relative to 1990, gross United States GHG emissions in 2018 were higher by 3.7%, down from a high of 15.2% above 1990 levels in 2007. GHG emissions decreased from 2017 to 2018 by 2.9% (188.4 MMT CO 2e), and overall, net emissions in
2018 were 10.2% below 2005 levels (EPA 2020a).
According to California’s 2000–2018 GHG emissions inventory (2020 edition), California emitted 425 MMT CO2e in 2018, including emissions resulting from out-of-state electrical generation (CARB 2020). The sources of GHG emissions in California include transportation, industrial uses, electric power production from both in-state and out-of- state sources, commercial and residential uses, agriculture, high-GWP substances, and recycling and waste. The California GHG emission source categories and their relative contributions in 2018 are shown in Table 11.

a Percentage of total has been rounded and total may not sum due to rounding. b Includes emissions associated with imported electricity, which account for 24.57 MMT CO2e.
The City’s community-wide GHG emissions baseline in ventory in 2012 was estimated to be 599,000 MT CO 2e (City of San Marcos 2020b). On-road transportation is the largest contributor to the emissions, accounting for 54% (or 322,000 MT CO 2e) of the City’s 2012 total, followed by electricity at 27% (or 162,000 MT CO 2e) of the

emissions. Accounting for future population and economic growth, the City projects GHG emissions of 526,000 MT CO2e in 2020 and 429,000 MT CO2e in 2030. The projections assume population, housing, employment, and transportation activity will continue to grow over time, and accounts for GHG emission reductions associated with implementation of the City’s Climate Action Plan and legislative reductions (City of San Marcos 2020b).
3.1.5 Potential Effects of Climate Change
Globally, climate change has the potential to affect numerous environmental resources through uncertain impacts related to future air temperatures and precipitation patterns. The 2014 IPCC Synthesis Report indicated that warming of the climate system is unequivocal, and many of the observed changes since the 1950s are unprecedented. Signs that global climate change has o ccurred include warming of the atmosphere and ocean, diminished amounts of snow and ice pack, and rising sea levels (IPCC 2014).
In California, climate change impacts have the potential to affect sea-level rise, agriculture, snowpack and water supply, forestry, wildfire risk, public health, frequency of severe weather events, and electricity demand and supply. The primary effect of global climate change has be en a rise in average global tropospheric temperature.
Reflecting the long-term warming trend since pre-industrial times, observed global mean surface temperature for the decade 2006–2015 was 0.87°C (likely between 0.75°C and 0.99°C) higher than the average over the 1850–1900 period (IPCC 2018). Scientific modeling predicts that continued emissions of GHGs at or above current rates would induce more extreme climate changes during the twenty-first century than were observed during the twentieth century. Human activities are estimated to have caused approximately 1.0°C (1.8°F) of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C (1.4°F to 2.2°F) (IPCC 2018).
Global warming is likely to reach 1.5°C (2.7°F) between 2030 and 2052 if it continues to increase at the current rate (IPCC 2018).
Although climate change is driven by global atmospheric conditions, climate change impacts are felt locally. A scientific consensus confirms that climate change is al ready affecting California. The Office of Environmental Health Hazard Assessment identified various indicators of climate change in California, which are scientifically based measurements that track trends in various aspects of climate change. Many indicators reveal discernible evidence that climate change is occurring in California and is having significant, measurable impacts in the state.
Changes in the state’s climate have been observed, including an increase in annual average air temperature with record warmth from 2012 to 2016, more frequent extreme heat events, more extreme drought, a decline in winter chill, an increase in cooling degree days and a decrease in heating degree days, and an increase in variability of statewide precipitation (OEHHA 2018).
Warming temperatures and changing precipitation patterns have altered California’s physical systems—the ocean, lakes, rivers, and snowpack—upon which the state depends. Winter snowpack and spring snowmelt runoff from the Sierra Nevada and southern Cascade Mountains provid e approximately one-third of the state’s annual water supply. Impacts of climate on physical systems have been observed, such as high variability of snow-water content (i.e., amount of water stored in snowpack), decrease in spring snowmelt runoff, glacier change (loss in area), rise in sea levels, increase in average lake water temperature and coastal ocean temperature, and a decrease in dissolved oxygen in coastal waters (OEHHA 2018).
Impacts of climate change on biological systems, including humans, wildlife, and vegetation, have also been observed, including climate change impacts on terrestrial, marine, and freshwater ecosystems. As with global observations, species responses include those consistent with warming: elevational or latitudinal shifts in range,
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT

changes in the timing of key plant and animal life cycle events, and changes in the abundance of species and in community composition. Humans are better able to adapt to a changing climate than plants and animals in natural ecosystems. Nevertheless, climate change poses a threat to public health because warming temperatures and changes in precipitation can affect vector-borne pathogen transmission and disease patterns in California, as well as the variability of heat-related deaths and illness es. In addition, since 1950, the area burned by wildfires each year has been increasing (OEHHA 2018).
The California Natural Resources Agency (CNRA) has re leased four California Climate Change Assessments (2006, 2009, 2012, and 2018) that have addressed acceleration of warming across the state; more intense and frequent heat waves; greater riverine flows; accelerating sea-level rise; more intense and frequent drought; more severe and frequent wildfires; more severe storms and extreme weather events; shrinking snowpack and less overall precipitation; and ocean acidification, hypoxia, and warming. To address local and regional governments’ need for information to support action in their communities, the Fourth Assessment includes reports for nine regions of the state, including the San Diego region, where the project is located. Key projected climate changes for the San Diego region include the following (CNRA 2018a):
x Temperature is projected to increase substantially, by 5°F to 10°F, by the end of the twenty-first century.
Along with mean temperature, heat wave frequency will increase, with more intensity and longer duration.
Marine layer clouds can help to mitigate the impacts of temperature change in the coastal regions, although these clouds are not well represented in climate models, requiring further research. x Precipitation will remain highly variable but will change in character, with wetter winters, drier springs, and more frequent and severe droughts punctuated by more intense individual precipitation events.
Effects of an altered precipitation regime on ecosystems, water demand and supply, water quality, and flooding emergencies are incompletely known and will benefit from cross-disciplinary investigation. x Broadly, wildfire risk will likely increase in the future as climate warms. The risk for large catastrophic wildfires driven by Santa Ana wind events will also li kely increase as a result of drier autumns leading to low antecedent precipitation before the height of the Santa Ana wind season (December and January). x Sea level along the San Diego County coast is expected to rise approximately 1 foot by the mid-twenty-first century, and 3 feet or potentially much higher by 2100. For the next several decades, high tides combined with elevated shoreline water levels produced by both locally and distantly generated wind- driven waves will drive extreme events. Longer-term sea level will increase rapidly in the second half of the century and will be punctuated by short periods of storm-driven extreme sea levels that will imperil existing infrastructure, structures, and ecosystems with increasing frequency. San Diego is testing adaptation approaches, but sustained and improved observations in combination with physics-based modeling are needed to evaluate these adaptation measures and guide future planning. x Development in San Diego County is concentrated in the western one-third of the County, with approximately 60% of the land remaining undeveloped. Climate change, along with development and fragmentation, will act as significant stressors to San Diego’s natural lands, which are some of the most biodiverse in the United States. SANDAG’s regional planning emphasis on smart growth to concentrate urban development near city and transit centers supports conservation while using mitigating GHG emissions. x The San Diego County Water Authority, the region’s wa ter wholesaler, continues to diversify its supply by developing and negotiating local and nearby imported sources, developing more recycled water, and encouraging greater water conservation. There are several coordinated efforts in the region to build resilience to climate, and holistic water management adaptations are becoming more prevalent throughout

communities. Continued science and regional coordination to evaluate climate change impacts on future water supply, demand, and quality are needed to inform adaptation to future climate changes. x San Diego’s energy supply is rapidly changing with renewable energy sources, mostly photovoltaic arrays, increasing by more than 30% since 2010, which intr oduces novel sensitivities to weather variation and evolving vulnerability to climate changes. San Diego Gas & Electric (SDG&E) has installed a high-density weather station network that provides a more detailed, real-time awareness of weather conditions that could damage the energy system and/or produce unusual supply or demand. x Recent work in San Diego showed that heat-related health impacts are observed at lower temperatures in the coastal region than in the inland and desert regions. This is in part due to coastal residents being less acclimated to heat and less likely to have air conditioning. x Climate changes felt by San Diego County will also occur in northern Baja, Mexico. Binational coordination of climate adaptation measures present potential for significant benefit to communities on both sides of the border. However, to be effective, the approaches must navigate the complexity posed by different governance and community structures.
In March 2016, the CNRA released Safeguarding California: Implementation Action Plans, a document that shows how California is acting to convert the recommendations contained in the 2014 Safeguarding California plan (CNRA 2014) into action (CNRA 2016). Additionally, in May 2017, CNRA released the draft Safeguarding California Plan: 2017 Update, which is a survey of current programmatic responses for climate change and contains recommendations for further actions (CNRA 2017).
The CNRA released Safeguarding California Plan: 2018 Update in January 2018, which provides a roadmap for state agencies to protect communities, infrastructure, services, and the natural environment from climate change impacts. The 2018 Safeguarding California Plan includes 69 recommendations across 11 sectors, and more than 1,000 ongoing actions and next steps developed by scientific and policy experts across 38 state agencies (CNRA 2018b). As with previous state adaptation plans, the 2018 update addresses acceleration of warming across the state; more intense and frequent heat waves; greater riverine flows; accelerating sea-level rise; more intense and frequent drought; more severe and frequent wildfires; more severe storms and extreme weather events; shrinking snowpack and less overall precipitation; and ocean acidification, hypoxia, and warming.
3.2 Regulatory Setting
3.2.1 Federal
MMassachusettss v.. EPA. In Massachusetts v. EPA (April 2007), the U.S. Supreme Court directed the EPA administrator to determine whether GHG emissions from ne w motor vehicles cause or contribute to air pollution that may reasonably be anticipated to endanger public he alth or welfare, or whether the science is too uncertain to make a reasoned decision. In December 2009, the administrator signed a final rule with the following two distinct findings regarding GHGs under Section 202(a) of the federal Clean Air Act:
x The Administrator found that elevated concentrations of GHGs—CO 2, CH4, N2O, HFCs, PFCs, and SF 6—in
the atmosphere threaten the public health and welfar e of current and future generations. This is the “endangerment finding.”

x The Administrator further found the combined emissions of GHGs—CO 2, CH4, N2O, and HFCs—from new motor vehicles and new motor vehicle engines contribute to the GHG air pollution that endangers public health and welfare. This is the “cause or contribute finding.” These two findings were necessary to establish the foundation for regulation of GHGs from new motor vehicles as air pollutants under the Clean Air Act.
EEnergyy Independencee andd Securityy Act.. The Energy Independence and Security Act of 2007 (December 2007), among other key measures, would do the following, which would aid in the reduction of national GHG emissions:
1. Increase the supply of alternative fuel sources by setting a mandatory Renewable Fuel Standard requiring fuel producers to use at least 36 billion gallons of biofuel by 2022.
2. Set a target of 35 miles per gallon for the combined fleet of cars and light trucks by model year 2020 and direct National Highway Traffic Safety Administration (NHTSA) to establish a fuel economy program for medium- and heavy-duty trucks and create a separate fuel economy standard for work trucks.
3. Prescribe or revise standards affecting regional efficiency for heating and cooling products and procedures for new or amended standards, energy conservation, energy efficiency labeling for consumer electronic products, residential boiler efficiency, electric motor efficiency, and home appliances.
F
Federall Vehiclee Standards.. In response to a U.S. Supreme Court ruling, the Bush Administration issued Executive Order (EO) 13432 in 2007 directing the EPA, the Department of Transportation, and the Department of Energy to establish regulations that reduce GHG emissions from motor vehicles, non-road vehicles, and non-road engines by 2008. In 2009, the NHTSA issued a final rule regulating fuel efficiency and GHG emissions from cars and light- duty trucks for model year 2011, and in 2010, the EPA and NHTSA issued a final rule regulating cars and light- duty trucks for model years 2012–2016 (75 FR 25324–25728).
In 2010, President Barack Obama issued a memorandum directing the Department of Transportation, Department of Energy, EPA, and NHTSA to establish a dditional standards regarding fuel efficiency and GHG reduction, clean fuels, and advanced vehicle infrastructure. In response to this directive, the EPA and NHTSA proposed stringent, coordinated federal GHG and fuel economy standards for model years 2017–2025 light-duty vehicles. The proposed standards projected to achieve 163 grams per mile of CO 2 by model year 2025 on an
average industry fleet-wide basis, which is equivalent to 54.5 miles per gallon if this level were achieved solely through fuel efficiency. The final rule was adopted in 2012 for model years 2017–2021 (77 FR 62624–63200).
On January 12, 2017, the EPA finalized its decision to maintain the current GHG emissions standards for model years 2022–2025 cars and light trucks (EPA 2017d).
In addition to the regulations applicable to cars and light-duty trucks described above, in 2011, the EPA and NHTSA announced fuel economy and GHG standards for medium- and heavy-duty trucks for model years 2014– 2018 (76 FR 57106–57513). The standards for CO
2 emissions and fuel consumption are tailored to three main vehicle categories: combination tractors, heavy-duty pickup trucks and vans, and vocational vehicles. According to the EPA, this regulatory program will reduce GHG emissions and fuel consumption for the affected vehicles by 6%–23% over the 2010 baselines.
In August 2016, the EPA and NHTSA announced the adoption of the phase two program related to the fuel economy and GHG standards for medium- and heavy-duty trucks. The phase two program will apply to vehicles with model year 2018 through 2027 for certain trailers, and model years 2021 through 2027 for semi-trucks,

large pickup trucks, vans, and all types and sizes of buses and work trucks. The final standards are expected to lower CO2 emissions by approximately 1.1 billion MT and reduce oil consumption by up to 2 billion barrels over the lifetime of the vehicles sold under the program (EPA and NHTSA 2016).
In August 2018, the EPA and NHTSA proposed to amend certain fuel economy and GHG standards for passenger cars and light trucks and establish new standards for model years 2021 through 2026. Compared to maintaining the post- 2020 standards in place at the time, the 2018 proposal would increase U.S. fuel consumption by about half a million barrels per day (2%–3% of total daily consumption, according to the Energy Information Administration) and would impact the global climate by 3/1000th of 1°C by 2100 (EPA and NHTSA 2018). California and other states have stated their intent to challenge federal actions that would delay or eliminate GHG reduction measures, and have committed to cooperating with other countries to implement global climate change initiatives.
On September 27, 2019, the EPA and NHTSA published their Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule Part One: One National Program (84 FR 51,310), which became effective November 26, 2019. The Part One Rule revokes California’s authority to set its own GHG emissions standards and set zero-emission vehicle mandates in California. On March 31, 2020, the EPA and NHTSA issued Part Two of the SAFE Rule, which went into effect June 29, 2020 (85 FR 24174). The Part Two Rule set CO
2 emissions standards and corporate average fuel economy standards for passenger vehicles and light duty trucks for model years 2021 through 2026. On January 20, 2021, President Joe Biden issued an Executive Order on Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis, which includes review of the Part One Rule by April 2021 and review of the Part Two Rule by July 2021 (The White House 2021).
3.2.2 State
The statewide GHG emissions regulatory framework is summarized below by category: state climate change targets, building energy, renewable energy and energy procurement, mobile sources, solid waste, water, and other state regulations and goals. The following text describes executive orders, legislation, regulations, and other plans and policies that would directly or indirectly reduce GHG emissions and/or address climate change issues.
S
Statee Climatee Changee Targetss
The state has taken a number of actions to address climate change. These include executive orders, legislation, and CARB plans and requirements. These are summarized below.
Executivee Orderr S-3-05. EO S-3-05 (June 2005) established the following statewide goals: GHG emissions should be reduced to 2000 levels by 2010, GHG emissions should be reduced to 1990 levels by 2020, and GHG emissions should be reduced to 80% below 1990 levels by 2050.
EO S-3-05 also directed the California EPA to report biannually on progress made toward meeting the GHG targets and the impacts to California due to global warming, including impacts to water supply, public health, agriculture, the coastline, and forestry. The Climate Action Team was formed, which subsequently issued reports from 2006 to 2010 (CAT 2016).
Assemblyy Billl 32. In furtherance of the goals established in EO S-3-05, the legislature enacted AB 32 (Núñez and Pavley). The bill is referred to as the California Global Warming Solutions Act of 2006 (September 27, 2006). AB 32
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT
13170
54 February 2023
provided initial direction on creating a comprehensive multiyear program to limit California’s GHG emissions at 1990 levels by 2020 and initiate the transformations required to achieve the state’s long-range climate objectives.
EExecutivee Orderr B-55-18. EO B-55-18 (September 2018) establishes a statewide policy for the state to achieve carbon neutrality as soon as possible, and no later th an 2045, and achieve and maintain net-negative emissions thereafter. The goal is an addition to the existing statewide targets of reducing the state’s GHG emissions. CARB will work with relevant state agencies to ensure that future scoping plans identify and recommend measures to achieve the carbon neutrality goal.
Californiaa Airr Resourcess Board’ss Climatee Changee Scopingg Plan. One specific requirement of AB 32 was for CARB to prepare a scoping plan for achieving the maximum technologically feasible and cost-effective GHG emission reductions by 2020 (Health and Safety Code Section 38561[a]), and to update the plan at least once every 5 years. In 2008, CARB approved the first scoping plan. The Climate Change Scoping Plan: A Framework for Change (Scoping Plan) included a mix of recommended strategi es that combined direct regulations, market-based approaches, voluntary measures, policies, and other emission reduction programs calculated to meet the 2020 statewide GHG emissions limit and initiate the transforma tions needed to achieve the state’s long-range climate objectives. The key elements of the Scoping Plan include the following (CARB 2008):
1. Expanding and strengthening existing energy efficiency programs, as well as building and appliance standards.
2. Achieving a statewide renewable energy mix of 33%.
3. Developing a California cap-and-trade program that links with other Western Climate Initiative partner programs to create a regional market system and caps sources contributing 85% of California’s GHG emissions.
4. Establishing targets for transportation-related GHG emissions for regions throughout California, and pursuing policies and incentives to achieve those targets.
5. Adopting and implementing measures pursuant to existing state laws and policies, including California’s clean car standards, goods movement measures, and the Low Carbon Fuel Standard (17 CCR 95480 et seq.).
6. Creating targeted fees, including a public goods charge on water use, fees on high GWP gases, and a fee to fund the administrative costs of the State of California’s long-term commitment to AB 32 implementation.
The Scoping Plan also identified local governments as essential partners in achieving California’s goals to reduce GHG emissions because they have broad influence and, in some cases, exclusive authority over activities that contribute to significant direct and indirect GHG emissions through their planning and permitting processes, local ordinances, outreach and education efforts, and municipal operations. Specifically, the Scoping Plan encouraged local governments to adopt a reduction goal for munici pal operations, and for community emissions to reduce GHGs by approximately 15% from then levels (2008) by 2020. Many local governments developed community- scale local GHG reduction plans based on this Scoping Plan recommendation.
In 2014, CARB approved the first update to the Scoping Plan. The First Update to the Climate Change Scoping Plan: Building on the Framework (First Update) defined the state’s GHG emission reduction priorities for the next 5 years, and laid the groundwork to start the transition to the post-2020 goals set forth in EO S-3-05 and EO B-16- 2012. The First Update concluded that California is on track to meet the 2020 target but recommended a 2030 mid-term GHG reduction target be established to ensure a continuum of action to reduce emissions. The First Update recommended a mix of technologies in key economic sectors to reduce emissions through 2050, including energy demand reduction through efficiency and activity changes; large-scale electrification of on-road vehicles, buildings, and industrial machinery; decarboniz ing electricity and fuel supplies; and the rapid market

55 February 2023
penetration of efficient and clean energy technologies. As part of the First Update, CARB recalculated the state’s 1990 emissions level, using more recent GWPs identified by the IPCC, from 427 MMT CO 2e to 431 MMT CO 2e (CARB 2014).
In 2015, as directed by EO B-30-15, CARB began working on an update to the Scoping Plan to incorporate the 2030 target of 40% below 1990 levels by 2030 to keep Ca lifornia on its trajectory toward meeting or exceeding the long-term goal of reducing GHG emissions to 80% below 1990 levels by 2050 as set forth in EO S-3-05. The governor called on California to pursue a new and ambitious set of strategies, in line with the five climate change pillars from his inaugural address, to reduce GHG emissions and prepare for the unavoidable impacts of climate change. In the summer of 2016, the legislature affirmed the importance of addressing climate change through passage of SB 32.
In December 2017, CARB adopted California’s 2017 Climate Change Scoping Plan (2017 Scoping Plan) for public review and comment (CARB 2017b). The 2017 Scoping Plan builds on the successful framework established in the initial Scoping Plan and First Update while identifying new, technologically feasible and cost-effective strategies that will serve as the framework to achieve the 2030 GHG target as established by SB 32 and define the state’s climate change priorities to 2030 and beyond. The strategies’ commitments include implementing renewable energy and energy efficiency strategies (including the mandates of SB 350), increasing stringency of the Low Carbon Fuel Standard, implementing measures identified in the Mobile Source and Freigh t Strategies, implementing measures identified in the proposed Short-Lived Climate Pollutant Reduction Strategy, and increasing stringency of SB 375 targets. To fill the gap in additional reductions needed to achieve the 2030 target, it recommends continuing the Cap- and-Trade Program and a measure to reduce GHGs from refineries by 20%.
For local governments, the 2017 Scoping Plan replaced the initial Scoping Plan’s 15% reduction goal with a recommendation to aim for a community-wide goal of no more than 6 MT CO 2e per capita by 2030, and no more
than 2 MT CO 2e per capita by 2050, which are consistent with the state’s long-term goals. These goals are also consistent with the Under 2 Memorandum of Understand ing (Under 2 2016) and the Paris Agreement, which are developed around the scientifically based levels nece ssary to limit global warming to below 2°C. The 2017 Scoping Plan recognized the benefits of local governme nt GHG planning (e.g., through CAPs) and provided more information regarding tools CARB is working on to support those efforts. It also recognized the CEQA streamlining provisions for project-level review where there is a legally adequate CAP.12 The Scoping Plan recommends strategies for implementation at the statewide level to meet the goals of AB 32, SB 32, and the executive orders, and establishes an overall framework for the measures that will be adopted to reduce California’s GHG emissions. A project is considered consistent with the statutes and executive orders if it meets the general policies in reducing GHG emissions to facilitate the achievement of the state’s goals and does not impede attainment of those goals. A project would be consistent if it will further the objectives and not obstruct their attainment.
EExecutivee Orderr B-30-15. EO B-30-15 (April 2015) identified an interim GHG reduction target in support of targets previously identified under EO S-3-05 and AB 32. EO B-30-15 set an interim target goal of reducing statewide GHG emissions to 40% below 1990 levels by 2030 to keep California on its trajectory toward meeting or 12 Sierra Club v.

exceeding the long-term goal of reducing statewide GHG emissions to 80% below 1990 levels by 2050, as set forth in EO S-3-05. To facilitate achievement of this goa l, EO B-30-15 calls for an update to CARB’s Scoping Plan to express the 2030 target in terms of MMT CO2e. The executive order also calls for state agencies to continue to develop and implement GHG emissions reduction programs in support of the reduction targets. Sector-specific agencies in transportation, energy, water, and forestry were required to prepare GHG reduction plans by September 2015, followed by a report on action taken in relation to these plans in June 2016. EO B-30-15 does not require local agencies to take any action to meet the new interim GHG reduction target.
S
Senatee Billl 322 andd Assemblyy Billl 197. SB 32 and AB 197 (enacted in 2016) are companion bills that set a new statewide GHG reduction targets, make changes to CARB’s membership and increase legislative oversight of CARB’s climate change-based activities, and expand dissemination of GHG and other air-quality-related emissions data to enhance transparency and accountability. More specifically, SB 32 codified the 2030 emissions reduction goal of EO B-30-15 by requiring CARB to ensure that statewide GHG emissions are reduced to 40% below 1990 levels by 2030. AB 197 established the Joint Legislative Committee on Climate Change Policies, consisting of at least three members of the Senate and three members of the Assembly to provide ongoing oversight over implementation of the state’s climate policies. AB 197 also added two members of the Legislature to CARB as nonvoting members; requires CARB to make available and update (at least annually via its website) emissions data for GHGs, criteria air pollutants, and TACs from repo rting facilities; and requires CARB to identify specific information for GHG emissions reduction measures when updating the Scoping Plan.
Senatee Billl 6055 andd Senatee Billl 1383. SB 605 (2014) required CARB to complete a comprehensive strategy to reduce emissions of short-lived climate pollutants in the state, and SB 1383 (2016) required CARB to approve and implement that strategy by January 1, 2018. The Short-Lived Climate Pollutants Reduction Strategy was approved by CARB in March 2017, and lays out a range of options to reduce short-lived climate pollutant emissions in California, including regulations, incentives , and other market-supporting activities. SB 1383 also establishes specific targets for the reduction of short-lived climate pollutants (40% below 2013 levels by 2030 for CH
4 and HFCs, and 50% below 2013 levels by 2030 for anthropogenic black carbon), and provides direction for reductions from dairy and livestock operations and landfills. Accordingly, and as mentioned above, CARB adopted its Short-Lived Climate Pollutant Reduction Strategy in March 2017. This strategy establishes a framework for the statewide reduction of emissions of black carbon, CH4, and fluorinated gases.
Buildingg Energyy
Titlee 24,, Partt 6. Title 24 of the California Code of Regulations was established in 1978 and serves to enhance and regulate California’s building standards. Although not initially promulgated to reduce GHG emissions, Part 6 of Title 24 specifically established Building Energy E fficiency Standards that are designed to ensure new and existing buildings in California achieve energy efficiency and preserve outdoor and indoor environmental quality.
These energy efficiency standards are reviewed every fe w years by the Building Standards Commission and CEC, and revised if necessary (California Public Resources Code [PRC] Section 25402[b][1]). The regulations receive input from members of industry and the public, with the goal of “reducing of wasteful, uneconomic, inefficient, or unnecessary consumption of energy” (PRC Section 25402). These regulations are carefully scrutinized and analyzed for technological and economic feasibility (PRC Section 25402[d]) and cost effectiveness (PRC Sections 25402[b][2] and [b][3]). As a result, these standards save energy, increase electricity supply reliability, increase indoor comfort, avoid the need to construct new power plants, and help preserve the environment.

The 2019 Title 24 standards are the currently applicable building energy efficiency standards, and became effective on January 1, 2020. The 2019 Title 24 Building Energy Efficiency Standards will further reduce energy used and associated GHG emissions compared to prior standards. In general, single-family residences built to the 2019 standards are anticipated to use approximately 7% less energy due to energy efficiency measures than those built to the 2016 standards; once rooftop solar electricity generation is factored in, single-family residences built under the 2019 standards will use approximately 53% less energy than those under the 2016 standards (CEC 2018). Nonresidential buildings built to the 2019 standards are anticipated to use an estimated 30% less energy than those built to the 2016 standards (CEC 2018).
TTitlee 24,, Partt 11. In addition to the CEC’s efforts, in 2008, the California Building Standards Commission adopted the nation’s first green building standards. The California Green Building Standards Code (Part 11 of Title 24) is commonly referred to as California’s Green Building Standards (CALGreen), and establishes minimum mandatory standards and voluntary standards pertaining to the planning and design of sustainable site development, energy efficiency (in excess of the California Energy Code requ irements), water conservation, material conservation, and interior air quality. The CALGreen standards took ef fect in January 2011 and instituted mandatory minimum environmental performance standards for all ground-up, new construction of commercial, low-rise residential and state-owned buildings, schools, and hospitals. The CALGreen 2019 standards, which are the current standards, became effective January 1, 2020.
Titlee 20.. Title 20 of the California Code of Regulations requires manufacturers of appliances to meet state and federal standards for energy and water efficiency. Performance of appliances must be certified through the CEC to demonstrate compliance with standards. New appliances regulated under Title 20 include refrigerators, refrigerator-freezers, and freezers; room air conditioners and room air-conditioning heat pumps; central air conditioners; spot air conditioners; vented gas space heat ers; gas pool heaters; plumbing fittings and plumbing fixtures; fluorescent lamp ballasts; lamps; emergency lighting; traffic signal modules; dishwaters; clothes washers and dryers; cooking products; electric motors; low voltage dry-type distribution transformers; power supplies; televisions and consumer audio and video equipment; and battery charger systems. Title 20 presents protocols for testing for each type of appliance covered under the regulations, and appliances must meet the standards for energy performance, energy design, water performance, and water design. Title 20 contains three types of standards for appliances: federal and state standards fo r federally regulated appliances, state standards for federally regulated appliances, and state standards for non-federally regulated appliances.
Assemblyy Billl 1109. Enacted in 2007, AB 1109 required the CEC to adopt minimum energy efficiency standards for general-purpose lighting to reduce electricity consumpt ion by 50% for indoor residential lighting and by 25% for indoor commercial lighting.
SBB 1. SB 1 (Murray) (August 2006) established a $3 billion rebate program to support the goal of the state to install rooftop solar energy systems with a generation capacity of 3,000 megawatts through 2016. SB 1 added sections to the Public Resources Code, including Chapter 8.8 (California Solar Initiative), that require building projects applying for ratepayer-funded incentives for photovoltaic systems to meet minimum energy efficiency levels and performance requirements. Section 25780 established that it is a goal of the state to establish a self- sufficient solar industry. The goals included establishing solar energy systems as a viable mainstream option for homes and businesses within 10 years of adoption, and placing solar energy systems on 50% of new homes within 13 years of adoption. SB 1, also termed “Go Solar California,” was previously titled “Million Solar Roofs.”

CCaliforniaa ABB 14700 (Solarr Waterr Heating).. This bill established the Solar Water Heating and Efficiency Act of 2007. AB 1470 makes findings and declarations of the Legislature relating to the promotion of solar water heating systems and other technologies that reduce natural gas demand. AB 1470 defines several terms for purposes of the act. The bill required a commission to evaluate the data available from a specified pilot program, and to design and implement a program of incentives for the installation of 200,000 solar water heating systems in homes and businesses throughout the state by 2017.
Renewablee Energyy andd Energyy Procurementt
SB 1078 (2002) established the Renewables Portfolio Standard (RPS) program, which requires an annual increase in renewable generation by the utilities. Initially, the RPS required utilities to obtain 20% of their power from renewable sources by 2010. SB X1-2 (2011) subsequently expanded the RPS by establishing that 33% of the total electricity sold to retail customers in California per year by December 31, 2020, and in subsequent years, be secured from qualifying renewable energy sources. SB 350 (2015) further expanded the RPS by establishing that 50% of the total electricity sold to retail customers in California per year by December 31, 2030, be secured from qualifying renewable energy sources. And SB 100 (2018) further accelerated the RPS, requiring achievement of a 50% RPS by December 31, 2026, and a 60% RPS by December 31, 2030. SB 100 also established a new state policy goal that calls for eligible renewable energy resources and zero-carbon resources to supply 100% of electricity retail sales and 100% of electricity procured to serve all state agencies by December 31, 2045.
Under the program, a renewable electrical generation facility is one that uses biomass, solar thermal, photovoltaic, wind, geothermal, fuel cells using renewable fuels, small hydroelectric generation of 30 megawatts or less, digester gas, municipal solid waste conversion, landfill gas, ocean wave, ocean thermal, or tidal current, and that meets other specified requirements with respect to its location.

Statee Vehiclee Standards. AB 1493 (July 2002) was enacted in response to the transportation sector accounting for more than one-half of California’s CO2 emissions. AB 1493 required CARB to set GHG emission standards for passenger vehicles, light-duty trucks, and other vehicles determined by the state board to be vehicles that are primarily used for noncommercial personal transportation in the state. AB 1493 required that CARB set GHG emission standards for motor vehicles manufactured in 2009 and all subsequent model years. CARB adopted the standards in September 2004. EO B-16-12 (March 2012) required that state entities under the governor’s direction and control support and facilitate the rapid commercialization of zero-emissions vehicles. It ordered CARB, CEC, the California Public Utilities Commission, and other relevant agencies to work with the Plug-In Electric Vehicle Collaborative and the California Fuel Cell Partnership to establish benchmarks to help achieve goals by 2015, 2020, and 2025. On a statewide basis, EO B-16-12 established a target reduction of GHG emissions from the transportation sector equaling 80% less than 1990 levels by 2050. This directive did not apply to vehicles that have special performance requirements necessary for the protection of the public safety and welfare. As explained under the “Federal Vehicle Standards” descri ption above, the EPA and NHTSA approved the SAFE Vehicles Rule Part One and Two, which revoked California’s authority to set its own GHG emissions standards and set zero-emission vehicle mandates in California. Because the EPA rule is the subject of pending legal challenges, and because President Biden issued an executive order to review Part One and Part Two, this analysis used the best available information at this time, as set forth in EMFAC and assumed in CalEEMod.

EExecutivee Orderr S-1-07. Issued on January 18, 2007, EO S-1-07 sets a declining Low Carbon Fuel Standard for GHG emissions measured in CO 2e grams per unit of fuel energy sold in California. The initial target of the Low Carbon Fuel Standard was to reduce the carbon intensity of California passenger vehicle fuels by at least 10% by 2020. The Low Carbon Fuel Standard was subsequently amended in 2018 to require a 20% reduction in carbon intensity by 2030. This new requirement aligns with the California’s overall 2030 target of reducing climate changing emissions to 40% below 1990 levels by 2030, set by SB 32. CARB has adopted implementing regulations for both the 10% and 20% carbon intensity reduction targets.
Senatee Billl 375. SB 375 (2008) addresses GHG emissions associated with the transportation sector through regional transportation and sustainability plans. SB 37 5 required CARB to adopt regional GHG reduction targets for the automobile and light-truck sector for 2020 and 2035. Regional metropolitan planning organizations are then responsible for preparing a Sustainable Communities Strategy (SCS) within their Regional Transportation Plan (RTP). The goal of the SCS is to establish a forecasted development pattern for the region that, after considering transportation measures and policies, will achieve, if feasible, the GHG reduction targets. If an SCS is unable to achieve the GHG reduction target, a metropolita n planning organization must prepare an Alternative Planning Strategy demonstrating how the GHG reduction target would be achieved through alternative development patterns, infrastructure, or additional transportation measures or policies.
Pursuant to California Government Code Section 65080(b)(2)(K), an SCS does not regulate the use of land; supersede the land use authority of cities and counties; or require that a city’s or county’s land use policies and regulations, including those in a general plan, be consis tent with it. Nonetheless, SB 375 makes regional and local planning agencies responsible for developing those st rategies as part of the federally required metropolitan transportation planning process and the state-mandated housing element process.
In 2010, CARB adopted the SB 375 targets for the regional metropolitan planning organizations. The targets adopted for SANDAG in 2010 are a 7% reduction in per-capita passenger-vehicle GHG emissions by 2020 and a 13% reduction by 2035, measured relative to 2005 GHG emissions. In 2018, CARB adopted the second round of SB 375 reduction targets, and increased SANDAG’s 2020 target to a 15% reduction in per-capita passenger- vehicle GHG emissions, and the 2035 target to a 19% reduction using the same 2005 baseline.
SANDAG completed and adopted its 2050 RTP/SCS in October 2011. In November 2011, CARB, by resolution, accepted SANDAG’s GHG emissions quantification analysis and determination that, if implemented, the SCS would achieve CARB’s 2020 and 2035 GHG emissions reduction targets for the region.
After SANDAG’s 2050 RTP/SCS was adopted, a lawsuit was filed by the Cleveland National Forest Foundation and others (Cleveland National Forest Foundation v. San Diego Association of Governments (2017) 3 Cal. 5th 497). regarding analysis of EO S-3-05’s 2050 goal of an 80% reduction in GHG emissions from 1990 levels. The Supreme Court of California held that the Environmental Impact Report at issue was sufficient to inform the public, based on the information available at the time, about the regional plan’s GHG impacts and its potential inconsistency with state climate change goals without including an explicit analysis of the consistency of projected 2050 GHG emissions with the goals in the executive order.
In 2015, SANDAG adopted the next iteration of its RTP/S CS in accordance with statutorily mandated timelines and no subsequent litigation challenge was filed. More specifically, in October 2015, SANDAG adopted San Diego Forward: The Regional Plan (SANDAG 2015). Like the 2050 RTP/SCS, San Diego Forward: Regional Plan meets CARB’s 2020 and 2035 reduction targets for the region (SANDAG 2015). In December 2015, CARB, by resolution,
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT

accepted SANDAG’s GHG emissions quantification analysis and determination that, if implemented, the SCS would achieve CARB’s 2020 and 2035 GHG emissions reduction targets for the region.
AAdvancedd Cleann Carss Program. The Advanced Clean Cars program (January 2012) is an emissions-control program for model years 2015 through 2025. The program combines the control of smog- and soot-causing pollutants and GHG emissions into a single coordinated package. The package includes elements to reduce smog-forming pollution, reduce GHG emissions, promote clean cars, and provide the fuels for clean cars. To improve air quality, CARB implemented new emission st andards to reduce smog-forming emissions beginning with 2015 model year vehicles. It is estimated that by 20 25, cars will emit 75% less smog-forming pollution than the average new car sold in 2012. To reduce GHG emissions, CARB, in conjunction with the EPA and NHTSA, adopted new GHG standards for model year 2017 to 2025 vehicles; the new standards are estimated to reduce GHG emissions by 34% in 2025. The zero-emissions vehicle (ZEV) program will act as the focused technology of the Advanced Clean Cars program by requiring manufacturers to produce increasing numbers of ZEVs and plug-in hybrid electric vehicles in the 2018 to 2025 model years.
ABB 1236. AB 1236 (October 2015) (Chiu) required a city, county, or city and county to approve an application for the installation of electric vehicle charging stations, as defined, through the issuance of specified permits unless the city or county makes specified written findings based on substantial evidence in the record that the proposed installation would have a specific, adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact. AB 1236 provided for appeal of that decision to the planning commission, as specified. The bill provided that the implementation of consistent statewide standards to achieve the timely and cost-effective installation of electric vehicle charging stations is a matter of statewide concern. The bill required electric vehicle charging stations to meet specified standards. AB 1236 required a city, county, or city and county with a population of 200,000 or more residents to adopt an ordinance, by September 30, 2016, that created an expedited and streamlined permitting process for electric vehicle charging stations. The bill also required a city, county, or city and county with a population of fewer than 200,000 residents to adopt this ordinance by September 30, 2017.
Executivee Orderr B-16-12. EO B-16-12 (2012) directs state entities under the Governor’s direction and control to support and facilitate development and distribution ZEVs . On a statewide basis, EO B-16-12 also establishes a GHG emissions reduction target from the transportation sector equaling 80% less than 1990 levels by 2050. In furtherance of this executive order, the Governor convened an Interagency Working Group on ZEVs that has published multiple reports regarding the progress made on the penetration of ZEVs in the statewide vehicle fleet.
Senatee Billl 350. In 2015, SB 350 – the Clean Energy and Pollution Reduction Act – was enacted into law. As one of its elements, SB 350 establishes a statewide policy for widespread electrification of the transportation sector, recognizing that such electrification is required for achievement of the state’s 2030 and 2050 reduction targets (see California Public Utilities Code, Section 740.12).

ABB 939,, ABB 341,, andd ABB 1826.. In 1989, AB 939, known as the Integrated Waste Management Act (PRC Sections 40000 et seq.), was passed because of the increase in waste stream and decrease in landfill capacity. The statute established the California Integrated Waste Management Board, which oversees a disposal reporting system. AB 939 mandated a reduction of waste being disposed of where jurisdictions were required to meet diversion goals of all solid waste through source reduction, recycling, and composting activities of 25% by 1995 and 50% by 2000.

61 February 2023
AB 341 (Chapter 476, Statutes of 2011 [Chesbro]) amended the California Integrated Waste Management Act of 1989 to include a provision declaring that it is the policy goal of the state that not less than 75% of solid waste generated be source-reduced, recycled, or composted by 2020, and annually thereafter. In addition, AB 341 required the California Department of Resources Recycling and Recovery (CalRecycle) to develop strategies to achieve the state’s policy goal.
CalRecycle conducted several general stakeholder workshops and several focused workshops, and in August 2015 published a discussion document titled AB 341 Report to the Legislature, which identified five priority strategies that CalRecycle believed would assist the state in reaching the 75% goal by 2020, legislative and regulatory recommendations, and an evaluation of program effectiveness (CalRecycle 2012).
AB 1826 (Chapter 727, Statutes of 2014, effective 2016) requires businesses to recycle their organic waste (i.e., food waste, green waste, landscape and pruning waste, nonhazardous wood waste, and food-soiled paper waste that is mixed in with food waste) depending on the amount of waste they generate per week. This law also requires local jurisdictions across the state to implement an organic waste recycling program to divert organic waste generated by businesses, including multi-family residential dwellings that consist of five or more units. The minimum threshold of organic waste generation by businesses decreases over time, which means an increasingly greater proportion of the commercial sector will be required to comply.
W
Waterr
Executivee Orderr B-29-15.. In response to the ongoing drought in California, EO B-29-15 (April 2015) set a goal of achieving a statewide reduction in potable urban water usage of 25% relative to water use in 2013. The term of the executive order extended through February 28, 2016, although many of the directives have since become permanent water-efficiency standards and requirements. The executive order includes specific directives that set strict limits on water usage in the state. In response to EO B-29-15, the California Department of Water Resources modified and adopted a revised version of the Model Water Efficient Landscape Ordinance that, among other changes, significantly increased the requirements for landscape water use efficiency and broadened its applicability to include new development projects with smaller landscape areas.
EO B-37-16. Issued May 2016, EO B-37-16 directed the State Water Resources Control Board to adjust emergency water conservation regulations through the end of January 2017 to reflect differing water supply conditions across the state. The State Water Resources Control Board also developed a proposal to achieve a mandatory reduction of potable urban water usage that builds off the mandatory 25% reduction called for in EO B- 29-15. The State Water Resources Control Board and Department of Water Resources will develop new, permanent water use targets that build on the existing state law requirements that the state achieve 20% reduction in urban water usage by 2020. EO B-37-16 also specifies that the State Water Resources Control Board permanently prohibit water-wasting practices such as hosing off sidewalks, driveways, and other hardscapes; washing automobiles with hoses not equipped with a shut-off nozzle; using non-recirculated water in fountains and other decorative water features; watering lawns in a manner that causes runoff, or within 48 hours after measurable precipitation; and irrigating ornamental turf on public street medians.
Otherr Statee Regulationss andd Goalss
SBB 97.. SB 97 (Dutton) (August 2007) directed the Governor’s Office of Planning and Research to develop guidelines under CEQA for the mitigation of GHG emissions. In 2008, the Governor’s Office of Planning and Research issued a technical advisory as interim guidan ce regarding the analysis of GHG emissions in CEQA documents. The advisory indicated that the lead agency should identify and estimate a project’s GHG emissions,
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT
13170
62 February 2023
including those associated with vehicular traffic, energy consumption, water usage, and construction activities (OPR 2008). The advisory further recommended that the lead agency determine significance of the impacts and impose all mitigation measures necessary to reduce GHG em issions to a level that is less than significant. The CNRA adopted the CEQA Guidelines amendments in December 2009, which became effective in March 2010.
Under the amended CEQA Guidelines, a lead agency has the discretion to determine whether to use a quantitative or qualitative analysis or apply performance standards to determine the significance of GHG emissions resulting from a particular project (14 CCR 15064.4[a]). The CEQA Guidelines require a lead agency to consider the extent to which a project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions (14 CCR 15064.4[b]). The CEQA Guidelines also allow a lead agency to consider feasible means of mitigating the significant effects of GHG emissions, including reductions in emissions through the implementation of project features or off-site measures.
The adopted amendments do not establish a GHG emissions threshold, instead allowing a lead agency to develop, adopt, and apply its own thresholds of significance or those developed by other agencies or experts. The CNRA also acknowledged that a lead agency may consider compliance with regulations or requirements implementing AB 32 in determining the significance of a project’s GHG emissions (CNRA 2009a).
With respect to GHG emissions, the CEQA Guidelines st ate in Section 15064.4(a) that lead agencies should “make a good faith effort, to the extent possible on scientific and factual data, to describe, calculate or estimate” GHG emissions. The CEQA Guidelines note that an agency may identify emissions by either selecting a “model or methodology” to quantify the emissions or by relying on “qualitative analysis or other performance-based standards” (14 CCR 15064.4[a]). Section 15064.4(b) states that the lead agency should consider the following when assessing the significance of impacts from GHG emissions on the environment: the extent a project may increase or reduce GHG emissions as compared to th e existing environmental setting; whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project; and the extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions (14 CCR 15064.4[b]).
Executivee Orderr S-13-08. EO Order S-13-08 (November 2008) is intended to hasten California’s response to the impacts of global climate change, particularly sea-level rise. Therefore, the executive order directs state agencies to take specified actions to assess and plan for such impacts. The final 2009 California Climate Adaptation Strategy report was issued in December 2009 (CNRA 2009b), and an update, Safeguarding California: Reducing Climate Risk, followed in July 2014 (CNRA 2014). To assess the state’s vulnerability, the report summarizes key climate change impacts to the state for the following areas: agriculture, biodiversity and habitat, emergency management, energy, forestry, ocean and coastal ecosystems and resources, public health, transportation, and water.
3.2.3 Local
Cityy off Sann Marcoss Climatee Actionn Plann
The City adopted its CAP on December 8, 2020 (City of San Marcos 2020b). The CAP acts as a roadmap to address challenges of climate change within the City. The CAP builds on the efforts and strategies identified in the City’s 2013 CAP and establishes GHG emission reduction targets and identifies achievable, locally based actions to reduce GHG emissions from municipal and community activities. The CAP includes a baseline GHG emissions inventory for 2012, GHG emissions forecasts for 2020 and 2030, local GHG emissions reduction strategies and measures to help the City achieve the 2030 target, climate adaptation measures for the City, and implementation

and monitoring mechanisms to ensure the City’s measures and targets are achieved. The CAP established GHG emissions reduction goals of 4% below 2012 levels by 2020 and 42% below 2012 levels by 2030 (City of San Marcos 2020b). The CAP was prepared in accordance with the requirements within CEQA Guidelines Section 15183.5, and the CAP Consistency Checklist was used to evaluate the proposed project’s significance with respect to GHG emissions.
C
Cityy off Sann Marcoss Generall Plann
The City’s General Plan (City of San Marcos 2013) includes various policies related to reducing GHG emissions.
Applicable policies include the following:
Landd Usee andd Communityy Designn Elementt
Policyy LU-2.1: Promote compact development patterns that reduce air pollution and automobile dependence and facilitate walking, bicycling, and transit use.
Policyy LU-2.3: Promote landscaping (e.g., native, drought tolerant plants) that minimizes demands on water supply.
Policyy LU-2.7: Promote the instillation of trees to reduce the urban heat-island effect and green infrastructure to reduce storm water runoff.
Policyy LU-3.1: Require that new development and redevelopment incorporate connections and reduce barriers between neighborhoods, transit corridors, and activity centers within the City.
Conservationn andd Openn Spacee Elementt
Policyy COS-4.5: Encourage energy conservation and the use of alternative energy sources within the community.
Policyy COS-4.6: Promote efficient use of energy and conservation of available resources in the design, construction, maintenance and operation of public and private facilities, infrastructure and equipment.
3.3 Significance Criteria and Methodology
3.3.1 Thresholds of Significance
California has developed guidelines to address the signif icance of GHG emissions impacts that are contained in Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.). Appendix G provides that a project would have a significant environmental impact if it would:
1. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment
2. Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases.
The Appendix G thresholds for GHGs do not prescribe specific methodologies for performing an assessment, do not establish specific thresholds of significance, and do not mandate specific mitigation measures. Rather, the CEQA Guidelines emphasize the lead agency’s discretion to determine the appropriate methodologies and
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT
13170
64 February 2023
thresholds of significance consistent with the manner in which other impact areas are handled in CEQA (CNRA 2009a). Additional guidance regarding assessment of GHGs is discussed below.
CCityy off Sann Marcoss CAPP Checklistt
The City adopted the Final CAP on December 8, 2020. The CAP relies on a screening threshold based on land use size and a CAP Consistency Checklist to determine whether a project’s emissions would be consistent with GHG emissions estimated within the City’s CAP. The CAP Consistency Checklist is used to determine significance in accordance with CEQA Guidelines Section 15183.5; therefore, the CAP Consistency Checklist was used to evaluate the proposed project’s significance with respect to GHG emissions.
3.3.2 Approach and Methodology
3.3.2.1 Construction
CalEEMod Version 2020.4.0 was used to estimate potential project-generated GHG emissions during construction. Construction of the project would result in GHG emissions primarily associated with use of off-road construction equipment, on-road hauling and vendor (material delivery) trucks, and worker vehicles. All details for construction criteria air pollutants discussed in Section 2.4.2.1, Construction, are also applicable for the estimation of construction-related GHG emissions for the proposed project. As such, see Section 2.4.2.1 for a discussion of project-generated construction emissions calculation methodology and assumptions.
Existingg Landd Usee Designationn
To compare the GHG emissions intensity of the proposed project and the land use built under the existing land use designation, the following section summarizes the construction methodology for the existing land use designation. Construction assumptions, including timing, phasing, equipment type and quantity, and worker and vendor truck trips, were based on the existing land us e alternative. The existing land use alternative assumed development of 480,000 square feet of research and development area with a 220,000 square foot (1,440 spaces) 4-story parking structure. Similar to the project, over 17 acres would be set aside for biological preservation.
Default values provided by CalEEMod were used where zoning information was not available. For purposes of estimating GHG emissions, it was assumed that construction of the land use built under the existing land use designation would commence in June 2023
13 and would end in December 2024. Construction of the land use built under the existing land use designation is anticipated to occur in five phases. Accordingly, five phases consisting of site preparation, grading, building construction, paving, and architectural coating were assumed. The analysis contained herein is based on the following assumptions (the duration of phases is approximate):
x Site Preparation: 1 month (June 2023)
x Grading: 2 months (June 2023 – July 2023)
13 The analysis assumes a construction start date of June 2023, whic h represents the earliest date construction would initiate (although unlikely). Assuming the earliest start date for constr uction represents the worst-case scenario for emissions because equipment and vehicle emission factors for later years would be slightly less due to more stringent standards for in-use off-ro ad equipment and heavy-duty trucks, as well as fleet turnover replacing older equipment and vehicles in later years.

x Architectural Coating: 1 month (October 2024 – November 2024) The construction equipment mix used for estimating the construction emissions of the existing land use designation is based on CalEEMod defaults and is shown in Table 12, Construction Scenario Assumptions – Existing Land Use Designation. For worker and vendor truck trips, the default CalEEMod assumptions for one-way trips were rounded up to the nearest even number to account for whole round trips. For this analysis, it was generally assumed that heavy construction equipment would operate 5 days a week (22 days per month) during project construction. Grading activities were anticipated to be minimal for the land use built under the existing land use designation; therefore, no haul trucks would be required to import or export material.

3.3.2.2 Operation
Similar to construction, emissions from the operational phase of the existing land use designation and project were estimated using CalEEMod. Operational year 2024 was assumed following completion of construction.
Areaa Sourcess
CalEEMod was used to estimate operational emissions from area sources, including emissions from landscape maintenance equipment. Emissions associated with natural gas usage in space heating and water heating were calculated in the building energy use module of CalEEMod, as described in the following text.
AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL REPORT
FOR THE PACIFIC PROJECT

66 February 2023
Landscape maintenance includes fuel combustion emissions from equipment such as lawn mowers, rototillers, shredders/grinders, blowers, trimmers, chainsaws, and hedge trimmers. The emissions associated with landscape equipment use were estimated based on CalEEMod default values for emission factors (grams per square foot of building space per day) and number of summer days (when landscape maintenance would generally be performed) and winter days. Based on CalEEMod defaults for the County, the average annual number of summer days is estimated at 180 days (CAPCOA 2021).
E
Energyy Sourcess
CalEEMod default values for electricity use and natural ga s consumption for each land use type were applied for the existing land use designation. The energy use from commercial and industrial land uses is calculated in CalEEMod based on the Commercial End-Use Survey (CAPCOA 2021). Energy use in buildings (both natural gas and electricity) is divided by CalEEMod into end-use categories subject to Title 24 requirements (end uses associated with the building envelope, such as the HVAC system, water heating system, and integrated lighting) and those not subject to Title 24 requirements (such as appliances, electronics, and miscellaneous “plug-in” uses).
Operational GHG emissions from energy sources include natural gas combustion for appliances and space and water heating. The current Title 24, Part 6 standards, referred to as the 2019 Title 24 Building Energy Efficiency Standards, became effective on January 1, 2020. The 2020.4.0 version of CalEEMod assumes compliance with the 2019 Title 24 Building Energy Efficiency Standards (CAPCOA 2021).
CalEEMod default energy intensity factors (CO
2, CH4, and N2O mass emissions per kilowatt hour) for SDG&E were based on the value for SDG&E’s energy mix in 2021. As explained in Section 3.2.2, SB X1-2 established a target of 33% from renewable energy sources for all electricity providers in California by 2020, and SB 350 calls for further development of renewable energy, with a target of 50% by 2030.
Mobilee Sources
The land use built under the existing land use designation would generate GHG emissions from mobile sources (vehicular traffic) as a result of trucks and employee vehicles. CalEEMod was used to estimate emissions from proposed vehicular sources (refer to Appendix A). CalEEMod default data, including trip rates, trip modes, trip lengths, fleet mix, and emissions factors, were used for the model inputs. CalEEMod default vehicle emission factors and vehicle fleet mix for 2024, as based on CARB’s EMFAC2017 model, were used to estimate emissions associated with vehicular sources.
Solidd Wastee
The land use built under the existing land use designatio n would generate solid waste and therefore would result in CO 2e emissions associated with landfill off-gassing. CalEEMod default values were used to estimate GHG emissions associated with solid waste.
Waterr andd Wastewaterr
Supply, conveyance, treatment, and distribution of water for the land use built under the existing land use designation require the use of electricity, which result in associated indirect GHG emissions. Similarly, wastewater generated by the land use built under the existing la nd use designation requires the use of electricity for

The project would generate GHG emissions from mobile sources (vehicular traffic) as a result of the residents of the project. CalEEMod was used to estimate emissions from proposed vehicular sources (refer to Appendix A). The trip rates from the SANDAG (Not So) Brief Guide of Vehicular Traffic Generation Rates for the San Diego Region were relied on for the proposed project (SANDAG 2002). CalEEMod default data, trip modes, trip lengths, fleet mix, and emissions factors were used for the model inputs.

Water consumption estimates for both indoor and outdoor water use relied on CalEEMod default assumptions.
3.4 Impact Analysis
This section evaluates the GHG emissions impacts associated with the project. The significance criteria described in Section 3.3.1, Thresholds of Significance, were used to evaluate impacts associated with the construction and operation of the project.

Cityy off Sann Marcos’’ Climatee Actionn Plann Consistencyy This section evaluates the project’s impacts to GHG in accordance with the City’s 2020 CAP Consistency Checklist. A completed CAP Checklist is included as Appendix C. The first step in this section evaluates a project’s GHG emissions consistent with the City’s Guidance to Demonstrating Consistency with the City of San Marcos Climate Action Plan: For Discretionary Projects Subject to CEQA (City’s Guidance Document) (City of San Marcos 2020c). New discretionary development projects subject to CEQA review that emit less than 500 MT CO 2e annually would not contribute considerably to cumulative climate change impacts, as stated in the City’s Guidance Document, and therefore, would be considered consistent with the CAP and associated emissions projections.
For projects that are subject to CAP consistency review, the next step in determining consistency is to assess the project’s consistency with the growth projections used in development of the CAP. This section allows the City to determine a project’s consistency with the land use assumptions used in the CAP.
Stepp 11
Questionn 11
Step 1 of the CAP Checklist determines land use consistency. Question 1 of Step 1 asks if a project is less than a certain size. It is deemed consistent with the City’s CAP by emitting fewer than 500 MT CO 2e per year and would
be less than significant. The proposed project is larger than the screening size (55 multi-family residential units) and therefore would answer Yes to this question and must proceed to Question 2 of Step 1.

QQuestionn 22
Question 2 of Step 1 asks if the project is consistent with the existing General Plan land use designation. The project proposes residential use, but the General Plan currently designates the site as Industrial (I). Therefore, the project would answer No to this question and would proceed to Question 3 of Step 1.
Questionn 33
Question 3 of Step 1 asks if the project would generate GHG emissions equal to or less than estimated GHG emissions generated under the land use built under the existing land use designation. The following section discusses the results of the construction and emissions analysis based on the methodologies described in Section 3.3.2.1, Construction, and Section 3.3.2.2, Operation, for the existing land use designation and proposed project.
Existingg Landd Usee Designationn
Constructionn Emissionss
Construction of the existing land use designation would result in GHG emissions that are primarily associated with use of off-road construction equipment, on-road vendor trucks, and worker vehicles. CalEEMod was used to calculate the GHG emissions based on the construction scenario described in Section 3.3.2.1, Construction, and Appendix A. Construction of the existing land use designation is anticipated to commence in June 2023, lasting a total of approximately 19 months. On-site sources of GHG emissions include off-road equipment and off-site sources include on-road vehicles (haul trucks, vendor trucks, and worker vehicles). Table 13 presents construction emissions for the existing land use designation from on-site and off-site emission sources.

Checklistt Itemm 8.. Urbann Treee Canopyy (Measuree C-2)) This checklist item applies to residential and non-residential projects and asks if the project is providing more than 10 parking spaces, will the project plant at least one tree per five parking spaces provided? The project would comply with this checklist item. The project is providing 927 parking spaces and will plant at least 186 trees to satisfy this checklist requirement. Accordingly, the proposed project would answer “Yes” to this question.
Summaryy
The project requires a General Plan Amendment because it is proposing a residential development on a site zoned as Industrial (I). Therefore, a GHG analysis was pe rformed to analyze the emissions of the existing zoned site and the project. The project was shown to result in fewer GHG emissions than the existing land use designation, and would implement all applicable checklist items within the City’s 2020 CAP. Therefore, the project would be consistent with the City’s 2020 CAP, and impacts to GHG emissions would be less than significant.
Consistencyy withh Statewidee Greenhousee Gass Reductionn Strategiess The project’s consistency with statewide GHG reduction st rategies is summarized in detail in Table 17 through consideration of the project’s various construction and operational components and their relationship to specified laws and regulations designed to reduce GHG emissions from such components.

As shown, the project would be consistent with and would not conflict with the applicable GHG-reducing strategies of the state that apply to the project’s construction and operational components.
In addition, CARB notes in the First Update that “California is on track to meet the near-term 2020 GHG limit and is well positioned to maintain and continue reductions beyond 2020 as required by AB 32” (CARB 2014). The project would help support achievement of the near-term 2020 goal (as codified in AB 32), the interim 2030 goal (as codified in SB 32), and the long-term, carbon neutrality 2045 goal (as set forth in EO B-55-18) by being infill development with access to multi-modal transportation options and incorporating design features such as installation of smart meters, installation of programmable thermostats, implementation of a parking management plan, walkability and bicycle access throughout the project site, walking access to the nearby Sprinter station, and drought-tolerant landscaping.
14 CConsistencyy withh SANDAG’ss RTP/SCSS
At the regional level, SANDAG’s RTP/SCS has been adopted for the purpose of reducing GHG emissions attributable to passenger vehicles in the San Diego region. In October 2015, SANDAG adopted its RTP/SCS, which meets CARB’s 2020 and 2035 reduction targets for the region. The RTP/SCS does not regulate land use or supersede the exercise of land use authority by SANDAG’s member jurisdictions, but itis a relevant regional reference document for purposes of evaluating the intersection of land use and transportation patterns and the corresponding GHG emissions. CARB has recognized that the approved RTP/SCS is consistent with SB 375 (CARB 2015b).
For purposes of the RTP/SCS consistency evaluation, the project would increase access to transit because it is located approximately 0.6 miles from the Palomar College Sp rinter station and a bus station is located in front of the project site.
15 The project would provide connectivity by extending the sidewalk to neighboring communities, the shopping center across South Las Posas Road, the bus station, and the Sprinter station. The project’s proximity to State Route 78 further allows for easy regional connectivity to employment centers, shopping areas, and recreation opportunities. Furthermore, the project would implement applicable measures in the City’s 2020 CAP Consistency Checklist (see Appendix C), installing electric vehicle charging stations, installing bicycle infrastructure, implementing a Transportation Demand Management plan, and reducing parking near transit.
These measures would further reduce the project’s GHG emissions from vehicle trips, increase access to transit, and encourage alternative modes of transportation. The project’s density, land use type, and location are consistent with SANDAG’s RTP/SCS, which provides for increased access to transit and promotes regional connectivity to employment centers, shopping areas, and recreation opportunities. The features mentioned above would help facilitate alternative transit usage and reduce the overall vehicle trips, thereby reducing the project’s regional GHG emissions.
14 GHG emission reductions from the listed design features were not quantified. 15 The City uses the North County Transit District (NCTD) for Coaster rail service, Sprinter light rail service, and Breeze bus service for connections throughout the County of San Diego. Sprinter service operates between Escondido and Oceanside with connections to Interstate 5 and the Coaster rail service operating out of the City of Oceanside. The NCTD operates the Palomar College Sprinter, which is within a short walk from the project area. In addition, a bus stop is located in front of the project site. Connections to Orange County can be made via the Metrolink in the City of Oceanside. Similarly, connections to Riverside Transit Authority buses can be made via the transit station in Oceanside and Escondido. Both the Metrolink connection in Oceanside and the Riverside Transit Authority Bus connection in Oceanside and Escondido are accessible through Sprinter light rail service. These public transit options will off er residents of the project area quick access to a variety of alternative modes of transportation.
