Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021

1.0 INTRODUCTION

1.1 PURPOSE OF THE REPORT
This report analyzes potential air quality, greenhouse gas (GHG) emissions, and energy usage impacts associated with the proposed Camino Largo Residential Project (project), which includes an evaluation of existing conditions in the project vicinity and an assessment of potential impacts associated with project construction and project operation. As appropriate, the analysis identifies measures that can be taken to avoid adverse air quality, GHG emissions, and energy usage impacts.

1.2 PROJECT LOCATION
The 9.3-acre project site (Assessor's Parcel Number [APN] 159-240-07) is located northeast of the intersection of North Santa Fe Avenue and Camino Largo in the City of Vista (City), south of the City's boundary with the County of San Diego. Guajome Adobe Park is located to the west and rural single- family residences and undeveloped land are to the south and east. See Figure 1, Regional Location, and Figure 2, Project Vicinity.

The existing site contains remnants of the former nursery, including hoop frames of the former greenhouses, palm trees in box planters, and piles of green waste. There is a structure that is associated with the former nursery operations located in the south-central portion of the site and trucks and machinery scattered throughout the site.

1.3 PROJECT DESCRIPTION
The proposed project involves the removal of the existing greenhouse and shed to construct 46 single- family residential units. The homes would range from 2,129 square feet to 2,374 square feet and extend to a height of no greater than 35 feet. Access would be provided by four private cul-de-sac drives that extend from Camino Largo. Resident parking would be provided via two -car garages and individual driveways with additional parking being provided along one side of each private drive. Two stormwater retention basins would be located onsite. One is located on the southwest corner of the site and another at the southeast edge of the site. See Figure 3, Site Plan. The project site's net density would be 46 units on 9.3 acres, which provides a gross density of 4.965 units per acre.

The project site has a General Plan land use designation of Rural Residential (RR) and would require a General Plan land use amendment to designate the site as Medium Low Density Residential (MDR) (10 dwelling units/acre). The project site would also require a zone change from Agricultural (A-1) to Residential (R-1-B 4,000-square foot lot).

1.4 CONSTRUCTION ACTIVITIES AND PHASING
The project would be constructed in one phase. Project construction activities would consist of demolition, site preparation, grading, installation underground utilities, internal street and parking area paving, building construction, and architectural coatings. Construction of the project would commence in April 2022 and be completed in approximately March 2023 for a total construction duration of approximately one year. A net export of approximately 44,130 cubic yards of soil and rock is anticipated during grading.

1.4.1 Construction Best Management Practices
The project would incorporate best management practices (BMPs) during construction to reduce emissions of fugitive dust. The San Diego Air Pollution Control District (SDAPCD) Rule 55 — Fugitive Dust Control states that no dust and/or dirt shall leave the property line. SDAPCD Rule 55 requires the following (SDAPCD 2009):
(1) Airborne Dust Beyond the Property Line: No person shall engage in construction or demolition activity subject to this rule in a manner that discharges visible dust emissions into the atmosphere beyond the property line for a period or periods aggregating more than 3 minutes in any 60-minute period.
(2) Track-Out/Carry-Out: Visible roadway dust as a result of active operations, spillage from transport trucks, erosion, or track-out/carry-out shall:
(i) be minimized by the use of any of the following or equally effective track-out/carry-out and erosion control measures that apply to the project or operation:
(a) track -out grates or gravel beds at each egress point; (b) wheel -washing at each egress during muddy conditions, soil binders, chemical soil stabilizers, geotextiles, mulching, or seeding; and for outbound transport trucks; (c) using secured tarps or cargo covering, watering, or treating of transported material; and (ii) be removed at the conclusion of each workday when active operations cease, or every 24 hours for continuous operations. If a street sweeper is used to remove any track -out/ carry -out, only PM10-efficient (particulate matter less than 10 microns) street sweepers certified to meet the most current South Coast Air Quality Management District (SCAQMD) Rule 1186 requirements shall be used. The use of blowers for removal of track-out/carry-out is prohibited under any circumstances.

The control measures listed below are the BMPs that the project would incorporate for dust control and are included in the modeling:
• A minimum of two applications of water shall be applied during grading between dozer/grader passes;
• Paving, chip sealing, or chemical stabilization of internal roadways shall be applied after completion of grading;
• Grading shall be terminated if winds exceed 25 miles per hour (mph); • All exposed surfaces shall maintain a minimum soil moisture of 12 percent; • Dirt storage piles shall be stabilized by chemical binders, tarps, fencing, or other erosion control; and
• Vehicle speeds shall be limited to 15 mph on unpaved roads.

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021

2.0 AIR QUALITY

2.1 AIR QUALITY REGULATORY SETTING
The project site is located within the San Diego Air Basin (SDAB). Air quality in the SDAB is regulated by the U.S. Environmental Protection Agency (USEPA) at the federal level, by the California Air Resources Board (CARB) at the state level, and by the SDAPCD at the regional level.

2.1.1 Air Pollutant Descriptors and Terminology

2.1.1.1 Criteria Air Pollutants
Criteria pollutants are defined by state and federal law as a risk to the health and welfare of the general public. In general, criteria air pollutants include the following compounds:
• Ozone (03)
• Carbon monoxide (CO)
• Nitrogen dioxide (NO2)
• Particulate matter (PM), which is further subdivided:
o Coarse PM, 10 microns or less in diameter (PM1o)
o Fine PM, 2.5 microns or less in diameter (PM2.5)
• Sulfur dioxide (S02)
• Lead (Pb)
Criteria pollutants can be emitted directly from sources (primary pollutants; e.g., CO, S02, PM10, PM2.5, and lead), or they may be formed through chemical and photochemical reactions of precursor pollutants in the atmosphere (secondary pollutants; e.g., ozone, NO2, PM1o, and PM2.5). PM10 and PM2.5 can be both primary and secondary pollutants. The principal precursor pollutants of concern are reactive organic gases ([ROGs] also known as volatile organic compounds [VOCs])' and nitrogen oxides (NOx).

The descriptions of sources and general health effects for each of the criteria air pollutants are shown in Table 1, Summary of Common Sources and Human Health Effects of Criteria Air Pollutants, based on information provided by the California Air Pollution Control Officers Association ([CAPCOA] 2021a).

Specific adverse health effects on individuals or population groups induced by criteria pollutant emissions are highly dependent on a multitude of interconnected variables such as cumulative concentrations, local meteorology and atmospheric conditions, and the number and characteristics of exposed individuals (e.g., age, gender). Criteria pollutant precursors (ROG and NOx) affect air quality on a regional scale, typically after significant delay and distance from the pollutant source emissions. Health effects related to ozone and NO2 are, therefore, the product of emissions generated by numerous sources throughout a region. Emissions of criteria pollutants from vehicles traveling to or from the project site (mobile emissions) are distributed nonuniformly in location and time throughout the region, 1 CARB defines and uses the term ROGs while the USEPA defines and uses the term VOCs. The compounds included in the lists of ROGs and VOCs and the methods of calculation are slightly different. However, for the purposes of estimating criteria pollutant precursor emissions, the two terms are often used interchangeably.

wherever the vehicles may travel. As such, specific health effects from these criteria pollutant emissions cannot be meaningfully correlated to the incremental contribution from the project.

2.1.1.2 Toxic Air Contaminants
Human Health Effects
Reduces the ability of blood to deliver
oxygen to vital tissues, affecting the
cardiovascular and nervous system. Impairs
vision, causes dizziness, and can lead to
unconsciousness or death.

Respiratory irritant; aggravates lung and
heart problems. Precursor to ozone and
acid rain. Contributes to climate change
and nutrient overloading, which
deteriorates water quality. Causes brown
discoloration of the atmosphere.

Irritates and causes inflammation of the
mucous membranes and lung airways;
causes wheezing, coughing, and pain when
inhaling deeply; decreases lung capacity;
aggravates lung and heart problems.

Damages plants; reduces crop yield.

Damages rubber, some textiles and dyes.

Increased respiratory symptoms, such as
irritation of the airways, coughing, or
difficulty breathing; aggravated asthma;
development of chronic bronchitis;
irregular heartbeat; nonfatal heart attacks;
and premature death in people with heart
or lung disease. Impairs visibility (haze).

Respiratory irritant. Aggravates lung and
heart problems. In the presence of
moisture and oxygen, sulfur dioxide
converts to sulfuric acid, which can damage
marble, iron and steel. Damages crops and
natural vegetation. Impairs visibility.

Precursor to acid rain.

Anemia, high blood pressure, brain and
kidney damage, neurological disorders,
cancer, lowered IQ. Affects animals, plants,
and aauatic ecosystems.

Toxic air contaminants (TACs) are a diverse group of air pollutants that may cause or contribute to an increase in deaths or in serious illness, or that may pose a present or potential hazard to human health.

TACs can cause long-term health effects such as cancer, birth defects, neurological damage, asthma, bronchitis, or genetic damage, or short-term acute effects such as eye watering, respiratory irritation HELIX

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
(a cough), runny nose, throat pain, and headaches. TACs may be carcinogenic or noncarcinogenic based on the nature of the health effects associated with exposure to the pollutant. For carcinogenic TACs, there is no level of exposure that is considered safe, and impacts are evaluated in terms of overall relative risk expressed as excess cancer cases per one million exposed individuals. Noncarcinogenic TACs differ in that there is generally assumed to be a safe level of exposure below which no negative health impact is believed to occur. These levels are determined on a pollutant -by -pollutant basis.

Diesel engines emit a complex mixture of air pollutants, including both gaseous and solid material. The solid material in diesel exhaust is referred to as diesel particulate matter (DPM). Almost all DPM is 10 microns or less in diameter, and 90 percent of DPM is less than 2.5 microns in diameter (CARB 2020a). Because of their extremely small size, these particles can be inhaled and eventually trapped in the bronchial and alveolar regions of the lung. In 1998, CARB identified DPM as a TAC based on published evidence of a relationship between diesel exhaust exposure and lung cancer and other adverse health effects. DPM has a notable effect on California's population —it is estimated that about 70 percent of total known cancer risk related to air toxics in California is attributable to DPM (CARB 2021a).

Asbestos is a mineral fiber that naturally occurs in some rock and soil. Long-term exposure to airborne asbestos fibers has been linked to major health effects including lung cancer; mesothelioma, a rare form of cancer that is found in the thin lining of the lung, chest, abdomen, and heart; and asbestosis, a serious progressive, long-term, non -cancer disease of the lungs (USEPA 2021a). Because of its fiber strength and heat resistance, asbestos has been used in a variety of building construction materials for insulation and as a fire retardant, primarily in buildings constructed before 1979. Asbestos fibers may be released into the air by the disturbance of asbestos containing material (ACM) during renovation and demolition activities; or during earth disturbing activities in areas where naturally occurring asbestos (NOA) is present in the rock or soil. NOA is not likely to be present in the soil and rock of San Diego County (California Department of Conservation 2000).

Lead is a naturally occurring metallic element that is found in small amounts in the earth's crust. In addition to its status as a criteria pollutant, lead is listed as a TAC because, depending on the level and duration of exposure, lead can adversely affect the nervous system, kidney function, immune system, reproductive and developmental systems and the cardiovascular system. There is also a probable link between lead exposure and kidney cancer, brain cancer (gliomas), and lung cancer (USEPA 2021b). Lead particulate matter can be emitted during demolition and renovation activities that disturb materials that contains lead -based paint (LBP), most typically found in structures built before 1978.

2.1.2 Federal Regulations

2.1.2.1 Clean Air Act
Air quality is defined by ambient air concentrations of specific pollutants identified by the USEPA to be of concern with respect to the health and welfare of the general public. The USEPA is responsible for enforcing the Federal Clean Air Act (CAA) of 1970 and its 1977 and 1990 Amendments. The CAA required the USEPA to establish National Ambient Air Quality Standards (NAAQS), which identify concentrations of pollutants in the ambient air below which no adverse effects on the public health and welfare are anticipated. In response, the USEPA established both primary and secondary standards for several criteria pollutants, which are introduced above. Table 2, Ambient Air Quality Standards, shows the federal and state ambient air quality standards (AAQS) for these pollutants.

The CAA allows states to adopt ambient air quality standards and other regulations provided they are at least as stringent as federal standards. CARB has established the more stringent California Ambient Air Quality Standards (CAAQS) for the six criteria pollutants through the California Clean Air Act of 1988 (CCAA), and has established CAAQS for additional pollutants, including sulfates, hydrogen sulfide (H2S), vinyl chloride, and visibility -reducing particles. Areas that do not meet the NAAQS or the CAAQS for a particular pollutant are "nonattainment areas" for that pollutant. Effective July 2, 2021, the San Diego Air Basin (SDAB) was classified as a Severe 15 nonattainment area for the 2015 8-hour NAAQS for ozone (USEPA 2021c). The SDAB is an attainment area for the NAAQS for all other criteria pollutants including PM10 and PM2.5. The SDAB is currently classified as a nonattainment area under the CAAQS for ozone, PM1o, and PM2.5 (SDAPCD 2021a).

2.1.3 State Regulations

2.1.3.1 California Clean Air Act
CARB has established the more stringent California Ambient Air Quality Standards (CAAQS) for the seven criteria air pollutants listed above through the California Clean Air Act of 1988 (CCAA), and has also established CAAQS for additional pollutants, including sulfates, hydrogen sulfide (1-12S), vinyl chloride and visibility -reducing particles (see Table 2). Areas that do not meet the CAAQS for a particular pollutant are considered to be "nonattainment areas" for that pollutant. The SDAB is currently classified as a nonattainment area under the CAAQS for ozone (1-hour and 8-hour), PMlo, and PM2.5 (SDAPCD 2020a).

The current state attainment status for the SDAB is provided in Table 3, above.

CARB is the state regulatory agency with the authority to enforce regulations to both achieve and maintain the NAAQS and CAAQS. The SDAPCD is responsible for developing and implementing the rules and regulations designed to attain the NAAQS and CAAQS, as well as the permitting of new or modified sources, developing of air quality management plans, and adopting and enforcing air pollution regulations for San Diego County.

2.1.3.2 State Implementation Plan
The CAA requires areas with unhealthy levels of ozone, inhalable particulate matter, carbon monoxide, nitrogen dioxide, and sulfur dioxide to develop plans, known as State Implementation Plans (SIPS). SIPS are comprehensive plans that describe how an area will attain the NAAQS. The 1990 amendments to the CAA set deadlines for attainment based on the severity of an area's air pollution problem.

SIPs are not single documents —they are a compilation of new and previously submitted plans, programs (e.g., monitoring, modeling, permitting), district rules, state regulations and federal controls. Many of California's SIPS rely on a core set of control strategies, including emission standards for cars and heavy trucks, fuel regulations and limits on emissions from consumer products. State law makes CARB the lead agency for all purposes related to the SIP. Local air districts and other agencies prepare SIP elements and submit them to CARB for review and approval. CARB forwards the SIP revisions to the USEPA for approval and publication in the Federal Register. The Code of Federal Regulations (CFR) Title 40, Chapter I, Part 52, Subpart F, Section 52.220 lists the items that are included in the California SIP (CARB 2009). At any one time, several California submittals are pending USEPA approval.

2.1.3.3 California Energy Code
California Code of Regulations (CCR) Title 24 Part 6, California's Energy Efficiency Standards for Residential and Nonresidential Buildings, were first established in 1978 in response to a legislative mandate to reduce California's energy consumption. Energy -efficient buildings require less electricity, natural gas, and other fuels. Electricity production from fossil fuels and on -site fuel combustion (typically for space and water heating) results primarily in GHG emissions. The California Energy Code is discussed in further detail in Section 3, below.

2.1.3.4 Toxic Air Contaminants
The Health and Safety Code (§39655, subd. (a)) defines a TAC as "an air pollutant which may cause or contribute to an increase in mortality or in serious illness, or which may pose a present or potential hazard to human health." A substance that is listed as a hazardous air pollutant pursuant to HELIX
Environmental Planning
11 /15/2022
PH1

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
subsection (b) of Section 112 of the CAA (42 United States Code Sec. 7412[b]) is a TAC. Under State law, the California Environmental Protection Agency (CaIEPA), acting through CARB, is authorized to identify a substance as a TAC if it determines the substance is an air pollutant that may cause or contribute to an increase in mortality or an increase in serious illness, or that may pose a present or potential hazard to human health.

2.1.4 Local Regulations

2.1.5 SDAPCD Attainment Plan
The SDAPCD and San Diego Association of Governments (SANDAG) are responsible for developing and implementing the clean air plan for the attainment and maintenance of the AAQS in the SDAB. The regional air quality plan for San Diego County is SDAPCD's 2020 Plan for Attaining the National Ambient Air Quality Standards for Ozone in San Diego County (Attainment Plan; SDAPCD 2020b). The Attainment Plan, which would be a revision to the state implementation plan (SIP), outlines SDAPCD's plans and control measures designed to attain the national ambient air quality standard (NAAQS) for ozone. These plans accommodate emissions from all sources, including natural sources, through implementation of control measures, where feasible, on stationary sources to attain the standards. Mobile sources are regulated by the USEPA and CARB, and the emissions and reduction strategies related to mobile sources are considered in the Attainment Plan and SIP.

The Attainment Plan relies on information from CARB and SANDAG, including mobile and area source emissions, as well as information regarding projected growth in San Diego County, to estimate future emissions and then determine from that the strategies necessary for the reduction of emissions through regulatory controls. The CARB mobile source emission projections and SANDAG growth projections are based on population and vehicle trends and land use plans developed by the cities and by the County of San Diego. While SANDAG collaborates with the SDAPCD on the development of the portion of the SIP applicable to the SDAB, the SDAPCD is the lead agency. As such, the SDAPCD is responsible for projecting all future mobile source emissions (using CARB's mobile source emissions inventory EMFAC).

2.1.6 San Diego Air Pollution Control District Rules and Regulations Future development pursuant to the project would be required to comply with SDAPCD Rules and Regulations which require the incorporation of BMPs during construction to reduce emissions of fugitive dust.

2.1.6.1 Rule 50 (Visible Emissions)
Particulate matter pollution impacts the environment by decreasing visibility (haze). These particles vary greatly in shape, size and chemical composition, and come from a variety of natural and manmade sources. Some haze -causing particles are directly emitted to the air such as windblown dust and soot.

Others are formed in the air from the chemical transformation of gaseous pollutants (e.g., sulfates, nitrates, organic carbon particles) which are the major constituents of PM2.5. These fine particles, caused largely by combustion of fuel, can travel hundreds of miles causing visibility impairment.

Visibility reduction is probably the most apparent symptom of air pollution. Visibility degradation is caused by the absorption and scattering of light by particles and gases in the atmosphere before it reaches the observer.

resulting in less clarity, color, and visual range. Light absorption by gases and particles is sometimes the cause of discolorations in the atmosphere but usually does not contribute very significantly to visibility degradation. Scattering by particulates impairs visibility much more readily. SDAPCD Rule 50 (Visible Emissions) sets emission limits based on the apparent density or opacity of the emissions using the Ringelmann scale (SDAPCD 1997).

2.1.6.2 Rule 51 (Nuisance)
SDAPCD Rule 51 (Nuisance) states that a person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance or annoyance to any considerable number of persons or to the public or which endanger the comfort, repose, health or safety of any such persons or the public or which cause or have a natural tendency to cause injury or damage to business or property. The provisions of the rule do not apply to odors emanating from agricultural operations in the growing of crops or raising of fowls or animals (SDAPCD 1976).

2.1.6.3 Rule 55 (Fugitive Dust Control)
SDAPCD Rule 55 (Fugitive Dust Control) requires action be taken to limit dust from construction and demolition activities from leaving the property line. Similar to Rule 50 (Visible Emissions), Rule 55 (Fugitive Dust Control) places limits on the amount of visible dust emissions in the atmosphere beyond the property line. It further stipulates that visible dust on roadways as a result of track-out/carry-out shall be minimized through implementation of control measures and removed at the conclusion of each workday using street sweepers (SDAPCD 2009).

2.1.6.4 Rule 67.0.1 (Architectural Coatings)
Construction of development within the Specific Plan is required to comply with SDAPCD Rule 67.0.1 (Architectural Coatings) which requires residential interior/exterior flat coatings to be less than or equal to 50 grams per liter VOC content and interior/exterior non -flat coatings to be less than or equal to 100 grams per liter VOC content (SDAPCD 2015).

2.1.6.5 Rule 1206 (Asbestos Removal, Renovation, and Demolition) Demolition activities for the removal of existing structures on the project site would be required to comply with SDAPCD Rule 1206 (Asbestos Removal, Renovation, and Demolition) which requires a facility survey to determine the presence or absence of ACM, regardless of the age of the facility (SDAPCD 2017).

2.2 AIR QUALITY EXISTING CONDITIONS
The project site is located in a generally suburban residential area 2.25 miles north of the City center.

Topographically, there is an east -west trending ridge situated in the north central portion of the project site. Elevations on the project site range from 362 feet above mean sea level (amsl) at the top of the ridge to 296 amsl in the southwestern corner of the property adjacent to Camino Largo. The project currently contains 10,600 square feet of greenhouses and sheds. Land uses surrounding the project site include the existing single-family homes to the south and east of the project. To the north is a nursery and one home and one trailer. To the west across N. Santa Fe Avenue is farmland and the Guajome Adobe (see Figure 2).

2.2.1 Climate/Meteorology
The climate in southern California, including the SDAB, is controlled largely by the large-scale meteorological condition that dominates the west coast of the United States: a seasonally semi- permanent high-pressure cell centered over the northeastern Pacific Ocean, called the Pacific high, which keeps most storms from affecting the California coast. Areas within 30 miles of the coast in the San Diego region, including the project site, experience moderate temperatures and comfortable humidity.

Temperature inversion layers (inversions; layers of warmer air over colder air) affect air quality conditions significantly because they influence the mixing depth (i.e., the vertical depth in the atmosphere available for diluting air contaminants near the ground). The highest air pollutant concentrations in the SDAB generally occur during inversions. During the summer, air quality problems in the SDAB are created due to the interaction between the ocean surface and the lower layer of the atmosphere, creating a moist marine layer. An upper layer of warm air mass forms over the cool marine layer, preventing air pollutants from dispersing upward. Additionally, hydrocarbons (VOCs) and NOx react under the strong, abundant sunlight in the San Diego region, creating smog. Light, daytime winds, predominantly from the west, further aggravate the condition by driving the air pollutants inland, toward the foothills. During the fall and winter, air quality problems are created due to CO and NOx emissions. High NOx levels usually occur during autumn or winter, on days with summer-like conditions.

The predominant wind direction in the vicinity of the project site is from the southwest and the average wind speed is approximately six mph; Iowa Environmental Mesonet [IEM] 2021). The annual average maximum temperature in the project area is approximately 74 degrees Fahrenheit ff ), and the annual average minimum temperature is approximately 52°F. Total precipitation in the project area averages approximately 13 inches annually. Precipitation occurs mostly during the winter and relatively infrequently during the summer (Western Regional Climate Center [WRCC] 2021).

2.2.2 Existing Air Quality
The SDAPCD operates a network of ambient air monitoring stations throughout the San Diego region.

The nearest air monitoring station closest to the project site is at Camp Pendleton/Oceanside, approximately 6 miles to the west. The closest air monitoring station with data for PM10 and PM2.5 is the San Diego -Kearny Villa Road monitoring station, approximately 28 miles south of the project site. The ambient pollutant concentrations collected at the stations during the last three available years (2018 through 2020) are shown in Table 4, Air Quality Monitoring Data. The data indicates exceedance of the state/federal 8-hour ozone standards on three days in 2020. No other air quality standards were determined to be exceeded from 2018 to 2020.

2.2.3 Sensitive Receptors
CARB and the Office of Environmental Health Hazard Assessment (OEHHA) have identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over 65, children under 14, infants (including in utero in the third trimester of pregnancy), and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis (CARB 2005; OEHHA 2015). Some land uses are considered more sensitive to air pollution than others due to the types of population groups or activities involved and are referred to as sensitive receptors.

Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers.

The closest existing sensitive receptors to the project site are single-family homes located adjacent to the project site to the south, north, and west. The closest existing school is the Guajome Park Academy, located at 2000 N Santa Fe Avenue, approximately 966 feet (0.18 mile) southwest of the project site.

2.3 AIR QUALITY METHODOLOGY
Air emissions from mobile, area, and energy sources were calculated using CaIEEMod, version 2020.4.0.

CalEEMod is a computer model used to estimate air emissions resulting from land development projects HELIX
Environmental Planning

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
throughout the state of California. CalEEMod was developed by CAPCOA in collaboration with the California air quality management and pollution control districts, primarily the SCAQMD. The calculation methodology, source of emission factors used, and default data is described in the CalEEMod User's Guide, and Appendices A, D, and E (CAPCOA 2021b).

In brief, CalEEMod is a computer model that estimates criteria air pollutant and greenhouse gas emissions from mobile (i.e., vehicular) sources, area sources (fireplaces, woodstoves, and landscape maintenance equipment), energy use (electricity and natural gas used in space heating, ventilation, and cooling; lighting; and plug-in appliances), water use and wastewater generation, and solid waste disposal. Emissions are estimated based on land use information input to the model by the user.

In the first module, the user defines the specific land uses that will occur at the project site. The user also selects the appropriate land use setting (urban or rural), operational year, location, climate zone, and utility provider. The input land uses, size features, and population are used throughout CalEEMod in determining default parameters and calculations in each of the subsequent modules. The input land use information consists of land use subtypes (such as the residential subtypes of single-family residential and multi -family medium -rise residential) and their unit or square footage quantities.

Subsequent modules include construction (including off -road vehicle emissions), mobile (on -road vehicle emissions), area sources (architectural coatings [painting], consumer products [cleansers, aerosols, solvents]), water and wastewater, and solid waste. Each module comprises multiple components including an associated mitigation module to account for further reductions in the reported baseline calculations. Other inputs include trip generation rates, trip lengths, vehicle fleet mix (percentage autos, trucks, etc.), trip distribution (percent work to home, etc.), duration of construction phases, construction equipment usage, grading areas, season, and ambient temperature, as well as other parameters.

In various places the user can input additional information and/or override the default assumptions to account for project- or location -specific parameters. For this assessment, the default parameters were not changed unless otherwise noted. The CalEEMod output files are included in Appendix A to this report.

2.3.1 Construction Emissions

2.3.1.1 Construction Activities
Construction emissions were estimated based on the timeline provided by the project applicant, which assumes construction would begin in April 2022 and would be completed in March 2023, for a total construction period of approximately 12 months. The quantity, duration, and intensity of construction activity influence the amount of construction emissions and related pollutant concentrations that occur at any one time. As such, the emission forecasts provided herein reflect a specific set of conservative assumptions based on the expected construction scenario wherein a relatively large amount of construction activity is occurring in a relatively intensive manner. Because of this conservative assumption, actual emissions could be less than those forecasted. If construction is delayed or occurs over a longer time period, emissions could be reduced because of (1) a more modern and cleaner - burning construction equipment fleet mix than assumed in CaIEEMod, and/or (2) a less intensive buildout schedule (i.e., fewer daily emissions occurring over a longer time interval).

Construction activities would include demolition, site preparation, grading, installation underground utilities, internal street and parking area paving, building construction, and architectural coatings.

The modeling assumes that no VOC containing coatings will be used. This also complies with SDAPCD Rule 67, as described in Section 2.1.4, limiting the VOC content of architectural coatings to 50 g/L for flat coating and 100 g/L for non -flat coatings and pavement traffic marking. Interior paint was assumed to be flat coatings and exterior paint was assumed to be non -flat coatings. The modeling also assumes fugitive dust control in accordance with the SDAPCD Rule 55 and the BMPs, described in Section 1.4.1, specifically watering exposed areas twice per day, enforcing a 15-mph speed limit on unpaved surfaces, and maintaining a minimum moisture content of 12 percent for unpaved roads.

2.3.1.2 Construction Off -Road Equipment
Construction would require the use of heavy off -road equipment. Construction equipment estimates are based on default values in CalEEMod, Version 2020.4.0 with additional equipment added for excavation for underground utilities, based on assumptions used for similar projects. Table 6, Construction Equipment Assumptions, presents a summary of the assumed equipment that would be involved in each stage of construction.

2.3.1.3 Construction On -Road Trips
Worker commute trips and vendor delivery trips were modeled based on CalEEMod defaults. Worker trips are anticipated to vary between 3 and 20 trips per day, depending on construction activity. Haul truck trips were based on the building area to be demolished, vegetation estimates from aerial images, and the grading plan cut/fill estimate. Approximately 48 total haul truck trips are anticipated during demolition, 5,516 total haul truck trips during grading. The CalEEMod default worker, vendor and haul trip distances were used in the model.

2.3.2 Operational Emissions

2.3.2.1 Area Source Emissions
Area sources include emissions from landscaping equipment, the use of consumer products, the reapplication of architectural coatings for maintenance, and hearths. Emissions associated with area sources were estimated using the CalEEMod default values with the exception of hearths —the project will not include wood burning stoves or fireplaces, or natural gas fireplaces.

2.3.2.2 Energy Emissions
Development within the project would use electricity for lighting, heating and cooling. Natural gas and electricity will be supplied by San Diego Gas and Electric.

The gas -fired devices that may be utilized for the project includer furnaces, hot water heaters, stoves, and ovens. As with all fossil fuel combustion, the substances emitted include greenhouse gases, criteria pollutants, and toxic substances.

Electricity generation typically entails the combustion of fossil fuels, including natural gas and coal, which is then transmitted to end users. A building's electricity use is thus associated with the off -site or indirect emission of GHGs at the source of electricity generation (power plant) and is included in the GHG analysis in Section 3, below.

2.3.2.3 Vehicular (Mobile) Sources
Operational emissions from mobile source emissions are associated with vehicle trip generation and trip length. Based on the project trip generation rate from the Local Mobility Analysis, the project would generate 460 average daily trips (Linscott, Law & Greenspan, Engineers [LLG) 2021). The CalEEMod default trip distances and purposes were used in the modeling.

2.4 AIR QUALITY SIGNIFICANCE CRITERIA
Thresholds used to evaluate potential air quality and odor impacts are based on applicable criteria in the State's California Environmental Quality Act (CEQA) Guidelines Appendix G. A significant air quality and/or odor impact could occur if the implementation of the proposed project would:
• Conflict with or obstruct implementation of the San Diego Attainment Plan or applicable portions of the SIP; or
• Result in a cumulatively considerable net increase of any criteria pollutant for which the SDAB is non -attainment under an applicable NAAQS or CAAQS; or
• Expose sensitive receptors to substantial pollutant concentrations; or • Result in other emissions (such as those leading to odors adversely affecting a substantial number of people.

To determine whether the project would result in a cumulatively considerable net increase of PMlo, PM2.5, or the ozone precursors NOx and VOCs, emissions were evaluated based on the quantitative HELIX
Environmental Planning

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
emission thresholds established by the SDAPCD. As part of its air quality permitting process, the SDAPCD has established thresholds in Rule 20.2 for the preparation of Air Quality Impact Assessments (SDAPCD 2019).

For CEQA purposes, these screening criteria were used as numeric methods to determine if the project would result in a significant impact to air quality or an adverse effect on human health. The screening thresholds are shown in Table 7, Screening -level Thresholds for Air Quality Impact Analysis.

SDAPCD Rule S1 (Nuisance) prohibits emissions from any source whatsoever in such quantities of air contaminants or other material, which cause injury, detriment, nuisance, or annoyance to the public health or damage to property. It is generally accepted that the considerable number of persons requirement in Rule S1 is normally satisfied when 10 different individuals/households have made separate complaints within 90 days. Odor complaints from a "considerable" number of persons or businesses in the area would be a significant, adverse odor impact.

2.5 AIR QUALITY IMPACT ANALYSIS

2.5.1 Issue 1: Consistency with the Regional Air Quality Plan The Attainment Plan outlines SDAPCD's plans, and control measures designed to attain the NAAQS for ozone. In addition, the SDAPCD relies on the SIP, which includes the SDAPCD's plans and control measures for attaining the ozone NAAQS. These plans accommodate emissions from all sources, HELIX

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
including natural sources, through implementation of control measures, where feasible, on stationary sources to attain the standards. Mobile sources are regulated by the CaIEPA and CARB, and the emissions and reduction strategies related to mobile sources are considered in the Attainment Plan and SIP.

The Attainment Plan relies on information from CARB and SANDAG, including projected growth in the San Diego County, and mobile, area, and all other source emissions to project future emissions and determine from that the strategies necessary for the reduction of stationary source emissions through regulatory controls. CARB's mobile source emission projections and SANDAG's growth projections are based on population, employment and transportation trends, and land use plans developed by the local governments. Accordingly, projects that propose development that is consistent with the population and employment growth anticipated by these land use plans would be consistent with the Attainment Plan. If a project proposes development that results in growth greater than that anticipated in the adopted land use plans and SANDAG's growth projections upon which the Attainment Plan is based, the project may conflict with the Attainment Plan and SIP and could have a potentially significant impact on air quality. This situation would warrant further analysis to determine if the project and the surrounding projects would exceed the growth projections used in the Attainment Plan for the specific subregional area.

The project site is designated as R-R and would require a General Plan Amendment to MDR to accommodate the 46 single family residences. The City has recognized the potential for the project site to accommodate denser residential land uses as is demonstrated in the parcel -specific analysis of potential housing sites that the City prepared to identify underutilized sites designated for residential or mixed -use development to meet the Regional Housing Needs Allocation (RHNA) targets for the 2021- 2029 planning period. This analysis, which is also included as Appendix B to the City's General Plan Housing Element Update, did not allocate a residential density to the site, but did identify the parcel as suitable for residential development (City 2021).

Specifically, the RHNA for the 2021-2029 planning period assigned Vista a new housing need of 2,561 units. As stated in the Housing Element Update, to address the current shortfall in capacity for potential housing development the City will process zoning amendments for sufficient sites with appropriate densities during 2022-2024 to fully accommodate the City's remaining housing need. Rezoned sites will be selected from the candidate sites as identified in the parcel specific analysis and will comply with the requirements of Government Code §65583.2(h) and (i), that outlines the stipulations for suitable housing sites.

By developing an underutilized site and helping the City meet its housing needs, the project would be consistent with the growth assumption used to develop the region's Attainment Plan. As such, residential growth in the City as a result of the project, and the related changes in regional emissions, are accounted for in the SIP, which is crafted to bring the basin into attainment for all criteria pollutants.

Additionally, as detailed in Section 2.5.2, below, the project would not result in any construction or operational period emissions in exceedance of established thresholds. Therefore, the proposed project would not conflict with or obstruct implementation of the Attainment Plan and impacts would be less than significant.

2.5.2 Issue 2: Cumulatively Considerable Net Increase of Nonattainment Criteria Pollutants
The project would generate criteria pollutants in the short-term during construction and the long-term during operation. To determine whether a project would result in a cumulatively considerable net increase in criteria pollutant emissions that would violate an air quality standard or contribute substantially to an existing or projected air quality violation, a project's emissions are evaluated based on the quantitative emission thresholds established by the SDAPCD (as shown in Table 7).

2.5.2.1 Construction Criteria Pollutant and Precursor Emissions The project's temporary construction emissions were estimated using CalEEMod as described in Section 2.3. The results of the modeling of the project's construction emissions of criteria pollutants and ozone precursors are shown in Table 8, Maximum Daily Construction Emissions. The data are presented as the maximum anticipated daily emissions for comparison with the SDAPCD thresholds. The complete CalEEMod output is provided in Appendix A to this report.

VOC = volatile organic compound; NOX = nitrogen oxides; CO = carbon monoxide; SOX = sulfur oxides; PM10 = particulate matter 10 microns or less in diameter; PMz.s = particulate matter 2.5 microns or less in diameter; SDAPCD = San Diego County Air Pollution Control District As shown in Table 9 the project's long-term emissions of criteria pollutants and precursors would not exceed the SDAPCD daily or annual screening thresholds. Therefore, the project's operational activities would not result in a cumulatively considerable net increase of criteria pollutants that would violate any air quality standard or contribute substantially to an existing or projected air quality violation, and the impact would be less than significant.

2.5.3 Issue 3: Impacts to Sensitive Receptors
Impacts to sensitive receptors are typically analyzed for operational period CO hotspots and exposure to TACs. An analysis of the project's potential to expose sensitive receptors to these pollutants is provided below.

2.5.3.1 Construction Diesel Particulate Matter Emissions Implementation of the project would result in the use of heavy-duty construction equipment, haul trucks, on -site generators, and construction worker vehicles. These vehicles and equipment could HELIX

generate the TAC DPM. Generation of DPM from construction projects typically occurs in a localized area (e.g., at the project site) for a short period of time. Because construction activities and subsequent emissions vary depending on the phase of construction (e.g., grading, building construction), the construction -related emissions to which nearby receptors are exposed to would also vary throughout the construction period. During some equipment -intensive phases such as grading, construction -related emissions would be higher than other less equipment -intensive phases such as building construction.

Concentrations of mobile -source DPM emissions are typically reduced by 70 percent at approximately 500 feet (CARB 2005).

The dose (of TAC) to which receptors are exposed is the primary factor used to determine health risk.

Dose is a function of the concentration of a substance in the environment and the extent of exposure a person has with the substance; a longer exposure period to a fixed amount of emissions would result in higher health risks. Current models and methodologies for conducting cancer health risk assessments are associated with longer -term exposure periods (typically 30 years for individual residents based on guidance from OEHHA) and are best suited for evaluation of long duration TAC emissions with predictable schedules and locations. These assessment models and methodologies do not correlate well with the temporary and highly variable nature of construction activities. Cancer potency factors are based on animal lifetime studies or worker studies where there is long-term exposure to the carcinogenic agent. There is considerable uncertainty in trying to evaluate the cancer risk from projects that will only last a small fraction of a lifetime (OEHHA 2015). Considering this information, the highly dispersive nature of DPM, and the fact that construction activities would occur at various locations throughout the project site, it is not anticipated that construction of the project would expose sensitive receptors to substantial DPM concentrations. Therefore, this impact would be less than significant.

2.5.3.2 Construction Asbestos and Lead -Based Paint Emissions Asbestos dust and lead are known carcinogens classified as TACs by CARB. Both may be found in buildings constructed prior to 1979 when lead was used in some paint and asbestos was used as a component of some building materials such as walls, ceilings, insulation, or fireproofing. Demolition of existing structures erected prior to 1979 could result in the disturbance of asbestos and lead building materials resulting in emissions.

Airborne asbestos is regulated in accordance with the National Emission Standards for Hazardous Air Pollutants (NESHAP) asbestos regulations. Federal and state regulations prohibit emissions of asbestos from demolition or construction activities. Following identification of friable asbestos, federal and state Occupational and Safety Health Administration (OSHA) regulations require that asbestos trained, and certified abatement personnel perform asbestos abatement and that all asbestos -containing materials removed from on -site structures be hauled to a licensed receiving facility and disposed of under proper manifest by a transportation company certified to handle asbestos. In accordance with the SDAPCD Rule 1206, Asbestos Removal, Renovation, and Demolition, prior to commencement of demolition operations and prior to submitting the notifications required by Section (e) of Rule 1206, a facility survey shall be performed to determine the presence or absence of asbestos containing materials, regardless of the age of the facility (SDAPCD 2017). USEPA's Lead Renovation, Repair and Painting Rule (RRP Rule) requires that firms performing renovation, repair, and painting projects that disturb lead -based paint in structures built before 1978 have their firm certified by USEPA (or an authorized state), use certified renovators who are trained by USEPA-approved training providers, and follow lead -safe work practices.

These regulations specify precautions and safe work practices that must be followed to minimize the potential for release of asbestos fibers or lead dust and require notice to federal and/or local HELIX

government agencies prior to beginning demolition or renovation that could disturb asbestos containing materials. Therefore, compliance with established regulations would ensure that potential impacts associated with asbestos containing materials and lead -based paint during project demolition activities would be less than significant.

2.5.3.3 Localized Carbon Monoxide Hotspots
A CO hotspot is an area of localized CO pollution caused by severe vehicle congestion on major roadways, typically near intersections. Vehicle exhaust is the primary source of CO. In an urban setting, the highest CO concentrations are generally found within close proximity to congested intersections.

Under typical meteorological conditions, CO concentrations tend to decrease as distance from the emissions source (i.e., congested intersection) increase. Project -generated traffic has the potential of contributing to localized "hot spots" of CO off site. Because CO is a byproduct of incomplete combustion, exhaust emissions are worse when fossil -fueled vehicles are operated inefficiently, such as in stop -and -go traffic or through heavily congested intersections, where the level of service (LOS) is severely degraded.

The CARB also recommends evaluation of the potential for the formation of locally high concentrations of CO, known as CO hot spots. A CO hot spot is a localized concentration of CO that is above the state or national 1-hour or 8-hour CO ambient air standards. To verify that the project would not cause or contribute to a violation of the 1-hour and 8-hour CO standards, an evaluation of the potential for CO hot spots at nearby intersections was conducted.

The project's Local Transportation Study (LLG 2021) evaluated whether there would be a change in the LOS at the intersections affected by the proposed Project. The potential for CO hot spots was evaluated based on the results of the transportation study. The Transportation Project -Level Carbon Monoxide Protocol (California Department of Transportation [Caltrans] 1998) was followed to determine whether a CO hot spot is likely to form due to project -generated traffic. In accordance with the Protocol, CO hot spots are typically evaluated when: (a) the LOS of an intersection decreases to an LOS E or worse; (b) signalization and/or channelization is added to an intersection; and (c) sensitive receptors such as residences, schools, hospitals, etc., are located in the vicinity of the affected intersection or roadway segment.

According to the transportation study, three intersections would operate at LOS E or F in the horizon year and experience an increase in delay from the Project:
• N Santa Fe Ave & Osborne Street — LOS E (AM)
• N Santa Fe Ave & Taylor Street — LOS E (AM)
• N Santa Fe Ave & Bobier Drive — LOS E/F (AM/PM)
Therefore, consistent with the CO Protocol, these findings indicate that further screening is required.

Although the SDAPCD does not, various air quality agencies in California have developed conservative screening methods. The screening methods of the Sacramento Metropolitan Air Quality Management District (SMAQMD) are used for this Project because ambient CO concentrations within the SMAQMD jurisdiction are higher than for the Project area, as measured by CARB, resulting in a more conservative analysis. The SMAQMD guidance states that a project will not result in a significant impact to local CO concentrations if it meets all of the below criteria:

HELIX

• The affected intersection carries less than 31,600 vehicles per hour; • The project does not contribute traffic to a tunnel, parking garage, bridge underpass, urban street canyon, below -grade roadway, or other location where horizontal or vertical mixing of air would be substantially limited; and
• The affected intersection, which includes a mix of vehicle types, is not anticipated to be substantially different from the County average, as identified by EMFAC or CalEEMod models (SMAQMD 2009).

The highest traffic volume at the affect intersections is estimated to be 4,510 vehicles at the intersection of North Santa Fe Avenue and East Bobier Drive during the AM peak hour (LLG 2021). The intersection is not located in a tunnel, urban canyon, or similar area that would limit the mixing of air, nor is the vehicle mix anticipated to be substantially different than the County average. There would be no potential for a CO hotspot or exceedance of State or federal CO ambient air quality standard because the maximum traffic volume would be substantially less than the 31,600 vehicles per hour screening level; because the congested intersection is located where mixing of air would not be limited; and because the vehicle mix would not be uncommon. The impact would be less than significant, and no mitigation measures are required.

2.5.4 Issue 4: Odors
As discussed above, the State of California Health and Safety Code Sections 41700 and 41705, and SDAPCD Rule 51, prohibit emissions from any source whatsoever in such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to the public health or damage to property. Any unreasonable odor discernible at the property line of the project site will be considered a significant odor impact.

According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting activities, refineries, landfills, dairies, and fiberglass molding operations (SCAQMD 1993).

The project, involving a residential development, would not include any of these uses nor are there any of these land uses in the project vicinity.

Emissions from construction equipment, such as diesel exhaust, and VOCs from architectural coatings and paving activities may generate odors; however, these odors would be temporary, intermittent, and not expected to affect a substantial number of people. Additionally, noxious odors would be confined to the immediate vicinity of construction equipment. By the time such emissions reach any sensitive receptor sites, they would be diluted to well below any level of air quality concern. Furthermore, short-term construction -related odors are expected to cease upon the drying or hardening of the odor - producing materials. Long-term operation of the project would not be a substantial source of objectionable odors. Therefore, the project would not create objectionable odors affecting a substantial number of people, and the impact would be less than significant.

3.0 GREENHOUSE GAS EMISSIONS

3.1 GHG SETTING

3.1.1 Climate Change Overview
Global climate change refers to changes in average climatic conditions on Earth including temperature, wind patterns, precipitation, and storms. Global temperatures are moderated by atmospheric gases.

These gases are commonly referred to as GHGs because they function like a greenhouse by letting sunlight in but preventing heat from escaping, thus warming the Earth's atmosphere.

GHGs are emitted by natural processes and human (anthropogenic) activities. Anthropogenic GHG emissions are primarily associated with: (1) the burning of fossil fuels during motorized transport, electricity generation, natural gas consumption, industrial activity, manufacturing, and other activities; (2) deforestation; (3) agricultural activity; and (4) solid waste decomposition.

The temperature record shows a decades -long trend of warming, with 2020 ranked as the warmest year on record with an increase of 1.84 degrees Fahrenheit compared to the 1951-1980 average (National Aeronautics and Space Administration [NASA] 2021). GHG emissions from human activities are the most significant driver of observed climate change since the mid-201h century (United Nations Intergovernmental Panel on Climate Change [IPCC] 2021). The IPCC constructed several emission trajectories of GHGs needed to stabilize global temperatures and climate change impacts. The statistical models show a "high confidence" that temperature increase caused by anthropogenic GHG emissions could be kept to less than two degrees Celsius relative to preindustrial levels if atmospheric concentrations are stabilized at about 450 parts per million (ppm) carbon dioxide equivalent (CO2e) by the year 2100 (IPCC 2021).

3.1.2 Greenhouse Gases
The GHGs defined under California's Assembly Bill (AB) 32 include carbon dioxide (CO2), methane (CH4), nitrous oxide (N20), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).

Carbon Dioxide. CO2 is the most important and common anthropogenic GHG. CO2 is an odorless, colorless GHG. Natural sources include the decomposition of dead organic matter; respiration of bacteria, plants, animals, and fungi; evaporation from oceans; and volcanic outgassing. Anthropogenic sources of CO2 include burning fuels, such as coal, oil, natural gas, and wood. Data from ice cores indicate that CO2 concentrations remained steady prior to the current period for approximately 10,000 years. The atmospheric CO2 concentration in 2010 was 390 ppm, 39 percent above the concentration at the start of the Industrial Revolution (about 280 ppm in 1750). As of November 2021, the CO2 concentration exceeded 415 ppm (National Oceanic and Atmospheric Administration [NOAA] 2021).

Methane. CH4 is the main component of natural gas used in homes. A natural source of methane is from the decay of organic matter. Geological deposits known as natural gas fields contain methane, which is extracted for fuel. Other sources are from decay of organic material in landfills, fermentation of manure, and cattle digestion.

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
Nitrous Oxide. N20 is produced by both natural and human -related sources. N20 is emitted during agricultural and industrial activities, as well as during the combustion of fossil fuels and solid waste.

Primary human -related sources of N20 are agricultural soil management, animal manure management, sewage treatment, mobile and stationary combustion of fossil fuel, adipic (fatty) acid production, and nitric acid production.

Hydrofluorocarbons. Fluorocarbons are gases formed synthetically by replacing all hydrogen atoms in methane or ethane with chlorine and/or fluorine atoms. Chlorofluorocarbons are nontoxic, nonflammable, insoluble, and chemically nonreactive in the troposphere (the level of air at Earth's surface). Chlorofluorocarbons were first synthesized in 1928 for use as refrigerants, aerosol propellants, and cleaning solvents. Because hydrofluorocarbons destroy stratospheric ozone, their production was stopped as required by the 1989 Montreal Protocol.

Sulfur Hexafluoride. SF6 is an inorganic, odorless, colorless, nontoxic, nonflammable gas. SF6 is used for insulation in electric power transmission and distribution equipment, in the magnesium industry, in semi -conductor manufacturing, and as a tracer gas for leak detection.

GHGs have long atmospheric lifetimes that range from one year to several thousand years. Long atmospheric lifetimes allow for GHG emissions to disperse around the globe. Because GHG emissions vary widely in the power of their climatic effects, climate scientists have established a unit called global warming potential (GWP). The GWP of a gas is a measure of both potency and lifespan in the atmosphere as compared to CO2. For example, because methane and N20 are approximately 29 and 273 times more powerful than CO2, respectively, in their ability to trap heat in the atmosphere, they have GWPs of 29 and 771, respectively (CO2 has a GWP of 1). CO2e is a quantity that enables all GHG emissions to be considered as a group despite their varying GWP. The GWP of each GHG is multiplied by the prevalence of that gas to produce CO2e.

Historically, GHG emission inventories have been calculated using the GWPs from the IPCC's Second Assessment Report (SAR). In 2007, IPCC updated the GWP values based on the latest science at the time in its Fourth Assessment Report (AR4). In 2021, IPCC again updated the GWP values based on the latest science in its Sixth Assessment Report (AR6) (IPCC 2021).

By applying the GWP ratios, project related CO2e emissions can be tabulated in metric tons per year.

Typically, the GWP ratio corresponding to the warming potential of CO2 over a 100-year period is used as a baseline. The atmospheric lifetime and GWP of selected GHGs are summarized in Table 10, Global Warming Potentials and Atmospheric Lifetimes.

3.2 GHG REGULATORY FRAMEWORK
All levels of government have some responsibility for the protection of air quality, and each level (federal, State, and regional/local) has specific responsibilities relating to air quality regulation. GHG emissions and the regulation of GHGs is a relatively new component of air quality management.

3.2.1 Federal GHG Regulations

3.2.1.1 Federal Clean Air Act
The U.S. Supreme Court ruled on April 2, 2007, in Massachusetts v. U.S. Environmental Protection Agency that CO2 is an air pollutant, as defined under the CAA, and that the USEPA has the authority to regulate emissions of GHGs. The USEPA announced that GHGs (including CO2, CH4, N20, HFC, PFC, and SF6) threaten the public health and welfare of the American people. This action was a prerequisite to finalizing the USEPA's GHG emissions standards for light -duty vehicles, which were jointly proposed by the USEPA and the United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA). The standards were established on April 1, 2010 for 2012 through 2016 model year vehicles and on October 15, 2012 for 2017 through 2025 model year vehicles (USEPA and NHTSA 2012).

3.2.1.2 Light -Duty Vehicle Greenhouse Gas Emissions Standards and Corporate Average Fuel Economy Standards
The USEPA and the NHTSA worked together on developing a national program of regulations to reduce GHG emissions and to improve fuel economy of light -duty vehicles. The USEPA established the first -ever national GHG emissions standards under the CAA, and the NHTSA established CAFE standards under the Energy Policy and Conservation Act. On April 1, 2010, the USEPA and NHTSA announced a joint Final Rulemaking that established standards for 2012 through 2016 model year vehicles. This was followed up on October 15, 2012, when the agencies issued a Final Rulemaking with standards for model years 2017 through 2025. On March 3, 2020, the agencies released the final Safer Affordable Fuel -Efficient Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks (SAFE Vehicles Rule). The purpose of the SAFE Vehicles Rule is "to correct the national automobile fuel economy and GHG emissions standards to give the American people greater access to safer, more affordable vehicles that are cleaner HELIX

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
for the environment." The direct effect of the rule is to eliminate the standards that were put in place to gradually raise average fuel economy for passenger cars and light trucks under test conditions from 37 miles per gallon (mpg) in 2020 to 50 mpg in 2025. The new SAFE Vehicles Rule freezes the average fuel economy level standards indefinitely at the 2020 levels. The new SAFE Vehicles Rule also results in the withdraw of the waiver previously provided to California for that State's GHG and zero emissions vehicle (ZEV) programs under Section 209 of the CAA (USEPA and NHTSA 2020). The combined USEPA GHG standards and NHTSA CAFE standards resolve previously conflicting requirements under both federal programs and the standards of the State of California and other states that have adopted the California standards. The SAFE Vehicles Rule Part I (SAFE-1), which withdraws the waiver, was published in September 2019 and Part II (SAFE-2), which finalizes the regulation, was published in April 2020. On April 26, 2021, the USEPA published the Notice of Reconsideration of Previous Withdrawal of a Waiver for California's Advanced Clean Car Program. The purpose of this Notice of Reconsideration is to seek comment on a number of issues in the SAFE-1 action including:
• Whether it was proper for the USEPA to reconsider a previously issued CAA waiver; • Whether USEPA's actions to withdraw California's waiver was appropriate; • Whether the SAFE-1 interpretation of the CAA that enabled USEPA to withdraw California's waiver was appropriate; and/or
• Whether the SAFE-1 interpretation of CAA Section 177 that could disallow other states' ability to adopt California GHG emission standards was appropriate.

3.2.2 California GHG Regulations
There are numerous State plans, policies, regulations, and laws related to GHG emissions and global climate change. Following is a discussion of some of these plans, policies, and regulations that (1) establish overall State policies and GHG emission reduction targets; (2) require State or local actions that result in direct or indirect GHG emission reductions for the proposed project; and (3) require CEQA analysis of GHG emissions.

3.2.2.1 California Energy Code
CCR Title 24 Part 6: California's Energy Efficiency Standards for Residential and Nonresidential Buildings were first established in 1978 in response to a legislative mandate to reduce California's energy consumption. Energy -efficient buildings require less electricity, natural gas, and other fuels. Electricity production from fossil fuels and on -site fuel combustion (typically for space and water heating) results in GHG emissions.

The Title 24 standards are updated approximately every three years to allow consideration and possible incorporation of new energy efficiency technologies and methods. The 2019 Title 24 standards went into effect on January 1, 2020. The 2019 update to the Building Energy Efficiency Standards focuses on several key areas to improve the energy efficiency of newly constructed buildings and additions and alterations to existing buildings. The most significant efficiency improvements to the residential standards are a requirement for onsite photovoltaic electricity generation (e.g., solar panels) for most new or modified residential building up to three stories high (California Energy Commission [CEC] 2019).

HELIX

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
The standards are divided into three basic sets. First, there is a basic set of mandatory requirements that apply to all buildings. Second, there is a set of performance standards —the energy budgets —that vary by climate zone (of which there are 16 in California) and building type; thus, the standards are tailored to local conditions. Finally, the third set constitutes an alternative to the performance standards, which is a set of prescriptive packages that are basically a recipe or a checklist compliance approach.

3.2.2.2 California Green Building Standards Code
The California Green Building Standards Code (CALGreen; CCR Title 24, Part 11) is a code with mandatory requirements for all nonresidential buildings (including industrial buildings) and residential buildings for which no other state agency has authority to adopt green building standards. The current 2019 Standards for new construction of, and additions and alterations to, residential and nonresidential buildings went into effect on January 1, 2020 (California Building Standards Commission [CBSC] 2019).

The development of CALGreen is intended to (1) cause a reduction in GHG emissions from buildings; (2) promote environmentally responsible, cost-effective, healthier places to live and work; (3) reduce energy and water consumption; and (4) respond to the directives by the Governor. In short, the code is established to reduce construction waste; make buildings more efficient in the use of materials and energy; and reduce environmental impact during and after construction.

CALGreen contains requirements for storm water control during construction; construction waste reduction; indoor water use reduction; material selection; natural resource conservation; site irrigation conservation; and more. The code provides for design options allowing the designer to determine how best to achieve compliance for a given site or building condition. The code also requires building commissioning, which is a process for the verification that all building systems, like heating and cooling equipment and lighting systems, are functioning at their maximum efficiency.

3.2.2.3 Executive Order S-3-05
On June 1, 2005, Executive Order (EO) S-3-05 proclaimed that California is vulnerable to climate change impacts. It declared that increased temperatures could reduce snowpack in the Sierra Nevada, further exacerbate California's air quality problems, and potentially cause a rise in sea levels. To avoid or reduce climate change impacts, EO S-3-05 calls for a reduction in GHG emissions to the year 2000 level by 2010, to year 1990 levels by 2020, and to 80 percent below 1990 levels by 2050.

3.2.2.4 Assembly Bill 32 — Global Warming Solution Act of 2006 The California Global Warming Solutions Act of 2006, widely known as AB 32, requires that the CARB develop and enforce regulations for the reporting and verification of statewide GHG emissions. CARB is directed to set a GHG emission limit, based on 1990 levels, to be achieved by 2020. The bill requires CARB to adopt rules and regulations in an open public process to achieve the maximum technologically feasible and cost-effective GHG emission reductions.

3.2.2.5 Senate Bill 375
Senate Bill (SB) 375, the Sustainable Communities and Climate Protection Act of 2008, supports the State's climate action goals to reduce GHG emissions through coordinated transportation and land use planning with the goal of more sustainable communities.

HELIX

11 /15/2022
PH1

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021
Under the Sustainable Communities Act, CARB sets regional targets for GHG emissions reductions from passenger vehicle use. In 2010, CARB established these targets for 2020 and 2035 for each region covered by one of the State's metropolitan planning organizations (MPOs). CARB periodically reviews and updates the targets, as needed.

Each of California's MPOs must prepare a Sustainable Communities Strategy (SCS) as an integral part of its regional transportation plan (RTP). The SCS contains land use, housing, and transportation strategies that, if implemented, would allow the region to meet its GHG emission reduction targets. Once adopted by the MPO, the RTP/SCS guides the transportation policies and investments for the region. CARB must review the adopted SCS to confirm and accept the MPO's determination that the SCS, if implemented, would meet the regional GHG targets. If the combination of measures in the SCS would not meet the regional targets, the MPO must prepare a separate alternative planning strategy (APS) to meet the targets. The APS is not a part of the RTP. Qualified projects consistent with an approved SCS or Alternative Planning Strategy categorized as "transit priority projects" would receive incentives to streamline CEQA processing.

The SANDAG is San Diego's local MPO and has responded to the requirements of SB 375 with the preparation of a regional transportation plan/sustainable communities strategy. San Diego Forward: The Regional Plan (SANDAG 2015) is discussed in greater detail in Section 3.2.3, below.

3.2.2.6 Senate Bill 743
On September 27, 2013, California Governor Jerry Brown signed SB 743 into law and started a process that changes transportation impact analysis as part of CEQA compliance. These changes include the elimination of auto delay, LOS, and other similar measures of vehicular capacity or traffic congestion as a basis for determining significant impacts for land use projects and plans in California. Further, parking impacts will not be considered significant impacts on the environment for select development projects within infill areas with nearby frequent transit service. According to the legislative intent contained in SB 743, these changes to current practice were necessary to balance the needs of congestion management more appropriately with statewide goals related to infill development, promotion of public health through active transportation, and reduction of GHG emissions.

3.2.2.7 Senate Bill 97
SB 97 required the Governor's Office of Planning and Research to develop recommended amendments to the State CEQA Guidelines for addressing GHG emissions, including the effects associated with transportation and energy consumption. The amendments became effective on March 18, 2010.

3.2.2.8 Executive Order B-30-15
On April 29, 2015, EO B-30-15 established a California GHG emission reduction target of 40 percent below 1990 levels by 2030. The EO aligns California's GHG emission reduction targets with those of leading international governments, including the 28 nation European Union. California is on track to meet or exceed the target of reducing GHG emissions to 1990 levels by 2020, as established in AB 32.

California's new emission reduction target of 40 percent below 1990 levels by 2030 will make it possible to reach the goal established by EO S-3-05 of reducing emissions 80 percent under 1990 levels by 2050.

3.2.2.9 Senate Bill 32 and Assembly Bill 197
As a follow-up to AB 32 and in response to EO-B-30-15, SIB 32 was passed by the California legislature in August 2016 to codify the EO's California GHG emission reduction target of 40 percent below 1990 levels by 2030 and requires the State to invest in the communities most affected by climate change. AB 197 establishes a legislative committee on climate change policies to help continue the State's activities to reduce GHG emissions.

3.2.2.10 Assembly Bill 1493 —Vehicular Emissions of Greenhouse Gases AB 1493 (Pavley) requires that CARB develop and adopt regulations that achieve "the maximum feasible reduction of GHGs emitted by passenger vehicles and light -duty truck and other vehicles determined by CARB to be vehicles whose primary use is noncommercial personal transportation in the State." On September 24, 2009, CARB adopted amendments to the Pavley regulations that intend to reduce GHG emissions in new passenger vehicles from 2009 through 2016. The amendments bind California's enforcement of AB 1493 (starting in 2009), while providing vehicle manufacturers with new compliance flexibility. The amendments also prepare California to merge its rules with the federal CAFE rules for passenger vehicles (CARB 2021d). In January 2012, CARB approved a new emissions -control program for model years 2017 through 2025. The program combines the control of smog, soot, and global warming gases and requirements for greater numbers of zero -emission vehicles into a single packet of standards called Advanced Clean Cars (CARB 2021d).

3.2.2.11 Assembly Bill 341
The State legislature enacted AB 341 (California Public Resource Code Section 42649.2), increasing the solid waste diversion target to 75 percent statewide. AB 341 requires all businesses and public entities that generate 4 cubic yards or more of waste per week to have a recycling program in place. The final regulation was approved by the Office of Administrative Law on May 7, 2012 and went into effect on July 1, 2012.

3.2.2.12 Executive Order S-01-07 —Low Carbon Fuel Standard This EO, signed by Governor Schwarzenegger on January 18, 2007, directs that a statewide goal be established to reduce the carbon intensity of California's transportation fuels by at least 10 percent by the year 2020. It orders that a Low Carbon Fuel Standard (LCFS) for transportation fuels be established for California and directs CARB to determine whether a LCFS can be adopted as a discrete early action measure pursuant to AB 32. CARB approved the LCFS as a discrete early action item with a regulation adopted and implemented in April 2010. Although challenged in 2011, the Ninth Circuit reversed the District Court's opinion and rejected arguments that implementing LCFS violates the interstate commerce clause in September 2013. As a result, CARB continues to implement the LCFS statewide.

3.2.2.13 California Air Resources Board: Climate Change Scoping Plan On December 11, 2008, CARB adopted the Scoping Plan (CARB 2008) as directed by AB 32. The Scoping Plan proposes a set of actions designed to reduce overall GHG emissions in California to the levels required by AB 32. Measures applicable to development projects include those related to energy - efficiency building and appliance standards, the use of renewable sources for electricity generation, regional transportation targets, and green building strategy. Relative to transportation, the 2008 Scoping Plan includes nine measures or recommended actions related to reducing VMT and vehicle GHG HELIX

emissions through fuel and efficiency measures. These measures would be implemented statewide rather than on a project -by -project basis.

In response to EO B-30-15 and SB 32, all state agencies with jurisdiction over sources of GHG emissions were directed to implement measures to achieve reductions of GHG emissions to meet the 2030 and 2050 targets. CARB was directed to update the Scoping Plan to reflect the 2030 target (CARB 2014). The mid-term target is critical to help frame the suite of policy measures, regulations, planning efforts, and investments in clean technologies and infrastructure needed to continue driving down emissions. In December 2017, CARB adopted the 2017 Climate Change Scaping Plan Update, the Strategy for Achieving California's 2030 Greenhouse Gas Target, to reflect the 2030 target set by EO B-30-15 and codified by SB 32 (CARB 2017). Currently, CARB is gathering information to prepare an updated Scoping Plan for 2022, which will be designed to achieving carbon neutrality by 2045 (CARB 2021c).

3.2.3 Regional GHG Policies and Plans

3.2.3.1 San Diego Association of Government's Regional Plan San Diego Forward: The Regional Plan (Regional Plan; SANDAG 2015) is the long-range planning document developed to address the region's housing, economic, transportation, environmental, and overall quality -of -life needs. The purpose is to provide direction and guidance on future regional growth (i.e., the location of new residential and non-residential land uses) and transportation patterns throughout the region as stipulated under SB 375. The Regional Plan establishes a planning framework and implementation actions that increase the region's sustainability and encourage "smart growth while preserving natural resources and limiting urban sprawl." The Regional Plan encourages local jurisdictions including the County of San Diego to increase residential and employment concentrations in areas with the best existing and future transit connections, and to preserve important open spaces. The focus is on implementation of basic smart growth principles designed to strengthen the integration of land use and transportation. General urban form goals, policies, and objectives are summarized as follows:
• Mix compatible uses.
• Take advantage of compact building design.
• Create a range of housing opportunities and choices.
• Create walkable neighborhoods.
• Foster distinctive, attractive communities with a strong sense of place. • Preserve open space, natural beauty, and critical environmental areas. • Strengthen and direct development towards existing communities. • Provide a variety of transportation choices.
• Make development decisions predictable, fair, and cost-effective. • Encourage community and stakeholder collaboration in development decisions.

The Regional Plan also addresses border issues, providing an important guideline for communities that have borders with Mexico. In this case, the goal is to create a regional community where San Diego, its neighboring counties, tribal governments, and northern Baja California mutually benefit from San Diego's varied resources and international location.

3.2.4 Local Greenhouse Gas Plans

3.2.4.1 City of Vista Climate Action Plan
The City of Vista (City) has developed the Climate Action Plan (CAP) to address the issues of climate change as it relates to growth in the City, and to protect the environment for visitors and residents alike (City 2012). The CAP was adopted in December of 2013. The intent of the plan is to reduce traffic congestion and solid waste generation, improve air quality, increase safety for pedestrians and cyclists, and encourage more efficient use of energy and water. Additionally, this CAP requires meaningful GHG reductions, in accordance with the guidelines of AB 32, the Governor's EO S-3-05, and CEQA guidelines, which will help improve the quality of life in the City. The implementation of the CAP will also help lead agencies to assess cumulative impacts of a project and provide a means for future projects to address GHG impacts under CEQA. A lead agency may conclude that a project's GHG impact is not cumulatively significant if the project demonstrates consistency with the City's CAP (CEQA Guidelines Section 15183.5[h][3]), thereby reducing overall project costs.

Through the CAP, the City has established goals and policies that incorporate environmental responsibility into its daily management of residential, commercial and industrial growth, education, energy and water use, air quality, transportation, waste reduction, economic development and open space and natural habitats to further their commitment. The development of the CAP coincides with City's General Plan Update. The CAP includes a community -wide emissions inventory calculated using the socioeconomic growth rates from the General Plan Update.

Various state policies have enacted programs that will also contribute to reduced GHG emissions in the City by the year 2020. Some of these policies include updated building codes for energy efficiency, the low carbon fuel standard, Pavley vehicle emissions standards and the Renewables Portfolio Standard for utility companies. By supporting the state in the implementation of these measures, the City will experience substantial GHG emissions reductions. In order to reach the 2020 reduction target, the City has included additional local reduction measures in the CAP which encourage energy efficiency and renewable energy in buildings, transit -oriented planning, water conservation and increase waste diversion.

3.2.4.2 City of Vista Municipal Code
The City Municipal Code, Chapter 13.17, Construction and Demolition Debris Recycling, requires all construction, demolition, and remolded projects within the City, with a total project value equal to or greater than $75,000 to divert at least 50 percent of the total construction and demolition debris generated by the project via reuse or recycling (City 2011).

3.3 GHG EXISTING CONDITIONS

3.3.1 Worldwide and National GHG Inventory
In 2018, total GHG emissions worldwide were estimated at 48,900 million metric tons (MMT) of CO2e emissions (Climate Watch 2021). The U.S. contributed the second largest portion (12 percent) of global GHG emissions in 2018 with 5,790 MMT CO2e, of which 82 percent was CO2 emission (Climate Watch 2021). On a national level, 91 percent of GHG emissions were associated with transportation and electricity generation (Climate Watch 2021).

3.3.2 State GHG Inventories
CARB performed statewide inventories for the years 1990 to 2019, as shown in Table 11, California State Greenhouse Gas Emissions by Sector. The inventory is divided into six broad sectors of economic activity:
agriculture, commercial, electricity generation, industrial, residential, and transportation. Emissions are quantified in MMT CO2e.

As shown in Table 11, statewide GHG source emissions totaled 431 MMT CO2e in 1990, 471 MMT CO2e in 2000, 449 MMT CO2e in 2010, and 418 MMT CO2e in 2019. Transportation -related emissions consistently contribute the most GHG emissions, followed by electricity generation and industrial emissions.

3.4 GHG METHODOLOGY
The project's GHG emissions were calculated using CalEEMod, as described in Section 2.3.

3.4.1 Construction GHG Emissions
Construction of the project would result in emissions of GHGs from the use of diesel -powered equipment, from worker vehicles traveling to and from the project site, and from trucks hauling material to and from the project site. The anticipated construction equipment and vehicle trips required for project construction are described in Section 2.3.

3.4.2 Operational GHG Emissions

3.4.2.1 Area Sources
This CalEEMod module estimates the GHG emissions that would occur from the use of hearths (e.g., wood or gas fireplaces and wood stoves), and landscaping equipment. This module also estimates emissions due to use of consumer products and architectural coatings that have volatile organic compounds (VOCs); however, these sources do not emit GHGs. The project will not include wood burning or natural gas fireplaces or woodstoves.

The use of landscape equipment emits GHGs associated with the equipment's fuel combustion.

CalEEMod estimates the number and type of equipment needed based on the number of summer days given the project's location as entered in the project characteristics module. The model defaults for landscaping equipment were assumed.

3.4.2.2 Vehicular (Mobile) Sources
Operational emissions from mobile source emissions are associated with project -related vehicle trip generation and trip length. Based on the trip generation rate from the Local Transportation Study prepared for the project, the project would generate 460 average daily trips (LLG 2021). All CalEEMod default trip purposes and distances were used in the modeling.

3.4.2.3 Energy Sources
GHGs are emitted as a result of activities in buildings for which electricity and natural gas are used as energy sources. GHGs are generated during the generation of electricity from fossil fuels off -site in power plants. These emissions are considered indirect and are calculated in CalEEMod as associated with a building's operation.

CalEEMod default energy values are based on the CEC-sponsored California Commercial End Use Survey (CEUS) and Residential Appliance Saturation Survey (RASS) studies, which identify energy use by building type and climate zone. Each land use type input to the land use module is mapped in the energy module to the appropriate CEUS and RASS building type.

Energy source emissions were estimated assuming implementation of energy -reducing project design features to comply with the 2019 Title 24 standards which include a requirement for new residential buildings with three or fewer residential floors to have on -site generation of electricity through photovoltaic (solar) panels. The project's residential buildings (46 dwelling units) total approximately 104,408 square feet of conditioned space and would require solar panels producing a minimum of 112.6 kilowatts (kW).2 The annual electricity generated by a rooftop mounted solar power system varies by the climate, amount of sunlight available per day, the pitch and orientation of the roof, and the efficiency of the electrical transmission. Assuming a capacity factor (CF) of 20%, which accounts for climate, daylight hours, roof pitch and orientation, and transmission loss, the power produced by the 2 Per the 2019 Title 24 residential building energy efficiency requirements, the minimum solar electrical generation required is calculated by kW = (CFA x A)/1000 + (DU * B), where CFA is the conditioned floor area, A is 0.572 (climate zone 13 [Western San Diego County] adjustment factor), DU is the total number of dwelling units, and B is 1.15 (climate zone 13 dwelling unit factor).

project's solar panels would be approximately 197,313 kilowatt-hours (kWhr) per year.3 The complete solar power requirement calculations are included with in Appendix B to this report.

3.4.2.4 Solid Waste Sources
The disposal of solid waste produces GHG emissions from anaerobic decomposition in landfills, incineration, and transportation of waste. CalEEMod determines the GHG emissions associated with disposal of solid waste into landfills. Portions of these emissions are biogenic. CalEEMod methods for quantifying GHG emissions from solid waste are based on the IPCC method using the degradable organic content of waste. A conservative 25 percent solid waste diversion rate was applied in CalEEMod to the new construction and redevelopment that would occur to account for mandatory compliance with AB 341.

3.4.2.5 Water and Wastewater Sources
The amount of water used, and wastewater generated, by a project has indirect GHG emissions associated with it. These emissions are a result of the energy used to supply, distribute, and treat the water and wastewater. In addition to the indirect GHG emissions associated with energy use, wastewater treatment can directly emit both methane and nitrous oxide.

CalEEMod uses default electricity intensity values for various phases of supplying and treating water from CEC's Refining Estimates of Water -Related Energy Use in California. The model estimates water/wastewater emissions by multiplying the total projected water/wastewater demand by the applicable water electricity intensities and by the utility intensity GHG factors.

The default CalEEMod water use assumptions were used for the GHG emissions estimates. For the project's water and wastewater GHG emissions, an overall 20 percent reduction in water use was applied in the CalEEMod mitigation section to account for recent requirements of CALGreen.

3.5 GHG SIGNIFICANCE CRITERIA
Given the relatively small levels of emissions generated by a typical project in relationship to the total amount of GHG emissions generated on a national or global basis, individual development projects are not expected to result in significant, direct impacts with respect to climate change. However, considering the magnitude of the impact of GHG emissions on the global climate, GHG emissions from new development could result in significant, cumulative impacts with respect to climate change. Thus, the potential for a significant GHG impact is limited to cumulative impacts.

According to Appendix G of the CEQA Guidelines, a project would have a significant environmental impact if it would:

1. Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment?
3 Solar kWhr per year can be calculated by: kWhr/year = Power Output (kW) x 24 hours/day x 365 days/year x CF, where CF is a capacity factor which accounts for climate, daylight hours, roof pitch and orientation, and transmission loss. For typical California residential systems, the CF can range between 17% and 22.5%. A CF of 20% was used in the project calculations.

Air Quality, Greenhouse Gas Emissions, and Energy Technical Report for the Camino Largo Residential Project I December 2021

2. Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs?
The determination of significance is governed by CEQA Guidelines 15064.4, entitled "Determining the Significance of Impacts from Greenhouse Gas Emissions." CEQA Guidelines 15064.4(a) states, "[t]he determination of the significance of greenhouse gas emissions calls for a careful judgment by the lead agency consistent with the provisions in section 15064. A lead agency should make a good -faith effort, based to the extent possible on scientific and factual data, to describe, calculate or estimate the amount of greenhouse gas emissions resulting from a project. A lead agency shall have discretion to determine, in the context of a particular project, whether to ... [use a quantitative model or qualitative model]" (emphasis added). In turn, CEQA Guidelines 15064.4(b) clarifies that a lead agency should consider "Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project." Therefore, consistent with CEQA Guidelines 15064.4, the GHG analysis for the project appropriately relies upon a threshold based on the exercise of careful judgement and believed to be appropriate in the context of this particular project.

Following the methods described by the California Air Pollution Control Officers Association (CAPCOA) in their report entitled "CEQA & Climate Change," dated January 2008, the City conducted a review of projects within the City to determine a 90 percent capture rate. As identified in the City's Interim Guidance Memorandum on Assessing GHG Emissions from Projects Subject to CEQA, it was determined that a level of 1,185 MT CO2e would capture 90 percent of the City's emissions that are attributable to development projects (City 2016). To determine whether the project is making a fair share contribution, and therefore substantial progress, towards meeting 2020 GHG emission targets set forth in the City's CAP, the project's emissions were evaluated based on this level. The City has determined that a fair share is provided if the project does not interfere with the State's implementation of GHG reduction programs identified for residential and commercial development. Provided the project is consistent with applicable plans, policies, and regulations adopted for the purpose of reducing GHG emissions, it would not result in a significant impact.

The interim threshold was developed to meet the statewide GHG emissions reduction target of 40 percent below 1990 levels by 2020 and be on track to meet the 80 percent below 1990 levels by 2050 target in accordance with SB 32 and EO S-3-05. The City has not adopted guidance or revised thresholds to account for GHG reduction target beyond 2020. Therefore, this analysis compares the project's emissions to a reduced threshold corresponding to the SB 32 reduction target of emissions 40 percent below 1990 levels by 2030. Accordingly, a threshold reduced by 4.98 percent for each year between 2020 and 2030 would meet the mandates of SB 32. The first full year of operation for the project is anticipated to be 2024. Therefore, a threshold 18.5 percent below the City threshold of 1,185 MT CO2e per service population per year, or 966 MT, is used in this analysis.

Neither the SDAPCD nor the City have adopted thresholds for determining the significance of a project's temporary construction GHG emissions. To be conservative in accounting for all the project's GHG emissions, the construction period emissions were amortized (i.e., averaged) over the anticipated 30-year lifespan of the project buildings and added to the project's operational emissions.

3.6 GHG IMPACT ANALYSIS

3.6.1 Issue 1: Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment.

3.6.1.1 Construction GHG Emissions
The project's temporary construction emissions were estimated using CalEEMod as described in Section 2.3. The results of the modeling of the project's GHG emissions shows that construction of the project would generate a total of 699.8 MT of CO2e. Amortized (averaged) over the anticipated 30-year lifespan of the project, project construction GHG emissions would be 23.3 MT of CO2e per year. The CalEEMod output is included as Appendix A to this report.

3.6.1.2 Operational GHG Emissions
The GHG emissions associated with long-term operation of the project were estimated using CalEEMod as described in Section 2.3 and Section 3.4. The results of the modeling of the project's operational GHG emissions are shown in Table 13, Operational GHG Emissions. The data are presented as the maximum anticipated operational GHG emissions for the first full year of operation (2024) and compared to the City threshold (adjusted for the year 2024). As shown in Table 13, the project's GHG emissions would be approximately 749.7 MT CO2e per year, which is below the 2024 adjusted City threshold of 966 MT CO2e per year. Therefore, the project would not generate GHG emissions that may have a significant impact on the environment, and the impact would be less than significant.

As such, the project would be consistent with local plans, policies, or regulations adopted for the purpose of reducing GHG emissions. Therefore, the project would not conflict with applicable plans, policies, and regulations related to GHG emission reductions, and the impact would be less than significant.

4.0 ENERGY
This section provides an evaluation of existing energy production/consumption conditions and potential energy use and related impacts from the project. The units of energy used in this section are the British thermal units (Btu), megawatt hours (MWh)4, therms, and gallons. A Btu is the quantity of heat required to raise the temperature of one pound of water one °F at sea level. Because the other units of energy can all be converted into equivalent Btu, the Btu is used as the basis for comparing energy consumption associated with different resources. A MWh is a unit of electrical energy, and one MWh is equivalent to approximately 3.413 million Btu (MMBtu), considering initial conversion losses (i.e., from one type of energy, such as chemical, to another type of energy, such as mechanical) and transmission losses.

Natural gas consumption is described typically in terms of cubic feet or therms; one cubic foot of natural gas is equivalent to approximately 1.05 MMBtu, and one therm represents 0.1 MMBtu. One gallon of gasoline/diesel is equivalent to approximately 0.125/0.139 MMBtu, respectively, considering energy consumed in the refining process.

4.1 ENERGY REGULATORY FRAMEWORK

4.1.1 Federal Energy Regulations

4.1.1.1 Energy Independence and Security Act of 2007
House of Representatives Bill 6 (HR 6), the federal Energy Independence and Security Act of 2007, established new standards for a few energy -consuming equipment types not already subject to a standard, and updated some existing standards. The most substantial new standard that HR 6 established is for general service lighting that is being deployed in two phases. First, phased in between 2012 through 2014, common light bulbs were required to use about 20 to 30 percent less energy than previous incandescent bulbs. Second, by 2020, light bulbs were required to consume 60 percent less energy than previous incandescent bulbs; this requirement will effectively phase out the incandescent light bulb.

MWh is the most common measure or electrical energy when discussing utility -scale electrical generation. Other common measures include kilowatt hours (kWh; 1,000 kWh = 1 MWh) and gigawatt hours (GWh; 1,000 MWh = 1 GWh).

4.1.2 California Energy Regulations

4.1.2.1 Renewable Energy Programs and Mandates (SB 1078, SB 107, SB 2 X1, SB 350 and SB 100)
A series of substantive and far-reaching legislative initiatives have been advanced at the State level in the last two decades. These initiatives focused on increasing the generation of electricity via renewable energy sources and promoting a shift from fossil- or carbon -based fuels as a key strategy to reduce GHG emissions, air pollution, and water use associated with the energy sector.

In 2002, California established the Renewables Portfolio Standard (RPS) with SB 1078, requiring electric utilities in the State to increase procurement of eligible renewable energy resources to achieve a target of 20 percent of their annual retail sales by the year 2010. In 2011, Governor Jerry Brown approved the California Renewable Energy Resources Act, SB 2 X1. SB 2 X1 legislatively broadens the scope of the State RPS to include retail electricity sellers; investor- and publicly owned utilities; municipal utilities; and community choice aggregators under the mandate to obtain 33 percent of their retail electrical energy sales from renewable sources by 2020.

Approved by Governor Brown on October 7, 2015, SB 350 increases California's renewable electricity procurement goal from 33 percent by 2020 to 50 percent by 2030. This will increase the use of Renewables Portfolio Standard eligible resources, including solar, wind, biomass, and geothermal. In addition, large utilities are required to develop and submit Integrated Resource Plans to detail how each entity will meet their customers' resource needs, reduce GHG emissions, and increase the use of clean energy.

Approved by Governor Brown on September 10, 2018, SB 100 extends the renewable electricity procurement goals and requirements of SB 350. SB 100 requires that all retail sale of electricity to California end -use customers be procured from 100 percent eligible renewable energy resources and/or zero -carbon resources by the end of 2045.

4.1.2.2 California Energy Plan
The CEC is responsible for preparing the State Energy Plan, which identifies emerging trends related to energy supply, demand, conservation, public health and safety, and the maintenance of a healthy economy. The plan calls for the state to assist in the transformation of the transportation system to improve air quality, reduce congestion, and increase the efficient use of fuel supplies with the fewest environmental and energy costs. To further this policy, the plan identifies a number of strategies, including aiding public agencies and fleet operators.

4.1.2.3 California Energy Code
As described in Section 3.2, the 2019 CCR Title 24 Part 6: California's Energy Efficiency Standards for Residential and Nonresidential Buildings contains reequipments for improving the energy efficiency of new or renovated buildings, including a requirement for onsite photovoltaic electricity generation (e.g., solar panels) for most new or modified residential building up to three stories high (CEC 2019).

California's electricity needs are satisfied by a variety of entities, including investor -owned utilities, publicly owned utilities, and electric service providers. As of 2019, California electricity demand totaled 272,576 gigawatt hours (GWh). In -state generating facilities accounted for about 190,913 GWh, or 70 percent of the total electric power used in the state, with the remaining electricity coming from out- of-state imports (CEC 2021b).

4.2.1.2 Natural Gas
Natural gas continues to play an important and varied role in California. In 2021, 48 percent of the natural gas burned in California was used for electricity generation, and much of the remainder was consumed in the residential (21 percent), industrial (25 percent), and commercial (9 percent) sectors (CEC 2021a). Natural gas supplies are currently plentiful and relatively inexpensive as a result of technological advances that allow recovery of natural gas from formations such as shale reservoirs that were previously inaccessible. However, potential environmental concerns are causing decision makers to reexamine the development of shale resources and consider tighter regulations, which could affect future natural gas supplies and prices.

4.2.1.3 Transportation Fuels
Automobiles and trucks consume gasoline and diesel fuel, which are nonrenewable energy products derived from crude oil, which in turn is derived from petroleum. In addition to energy consumption associated with on -road vehicle use, energy is consumed in connection with construction and maintenance of transportation infrastructure. Passenger cars and light -duty trucks are by far the largest consumers of transportation fuel. Retail sales of transportation fuel in California totaled 11.2 billion gallons of gasoline and 1.6 billion gallons of diesel in 2021 (CEC 2021c).

4.3 ENERGY METHODOLOGY
Construction and operational energy used were calculated based on the off -road equipment use and on - road vehicle trips and distances described in Section 2.3. Fuel consumption factors in terms of gallons per hour of diesel for off -road equipment were calculated using data from the CARB Mobile Source Emissions Inventory online database—OFFROAD2017 version 1.0.1 (CARB 2020a). Fuel consumption factors in terms of gallon of diesel and gasoline per mile travel were calculated from the CARB Mobile Source Emissions Inventory online data base—EMFAC2017 version 1.0.2 (CARB 2020b). The energy calculation sheets are included as Appendix B to this report.

4.4 ENERGY SIGNIFICANCE CRITERIA
According to Appendix G of the CEQA Guidelines, a project would have a significant environmental impact if it would:

Result in the wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation; and/or.
• Conflict with or obstruct a state or local plan for renewable energy or energy efficiency.

4.5 ENERGY IMPACT ANALYSIS

4.5.1 Issue 1: Result in the wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation.

4.5.1.1 Construction Energy
Energy consumed for project construction would primarily consist of fuels in the form of diesel and gasoline. Fuel consumption would result from: the use of on -road trucks for the transportation of construction materials and water; construction worker vehicles traveling to and from the project site; and from the use of off -road construction equipment. The estimated fuel and total energy consumed during project construction is shown in Table 14, Construction Energy Use. The full construction energy consumption calculation sheets are included as Appendix B to this report.

MMBtu = million British thermal units
While construction activities would consume petroleum -based fuels, consumption of such resources would be temporary and would cease upon the completion of construction. The petroleum consumed during project construction would be typical of similar residential projects and would not require the use of new petroleum resources beyond those typically consumed in California annually for construction activities. Based on these considerations, construction of the project would not result in wasteful, inefficient, or unnecessary consumption of energy resources and the impact would be less than significant.

4.5.1.2 Operational Energy
During long-term operation of the project, energy would be consumed in the form of diesel and gasoline used by vehicles traveling to and from the project site; natural gas for heating and hot water; electricity required to source and treat water used by the project; and electricity used directly by the project. As discussed in Section 3.4, the 2019 Title 24 Building Energy Efficiency Standards would require the project to provide a minimum of 112.6 kW of on -site photovoltaic generation capacity producing approximately 197,313 kWhr of electricity per year. The project's net electricity use calculation accounts for the on -site solar generation requirement. The project's operational energy use in gallons of fuel, electricity, and equivalent MMBtu is shown in Table 15, Operational Energy Use. The energy calculation sheets are included in Appendix C to this report.

kWh = kilowatt hours; MMBtu = million British thermal units As shown in Table 15, the project would result in an increase in annual energy consumption of approximately 16,078 MMBtu. While the project would increase the consumption of energy related to electricity, natural gas, water, and wastewater, because the project would be consistent with the City General Plan land use designation and zoning, the increase would be consistent with the energy projections for the state and the region based on the General Plan growth projections. Therefore, operation of the project would not result in wasteful, inefficient, or unnecessary consumption of energy resources and the impact would be less than significant.

4.5.2 Issue 2: Conflict with or obstruct a state or local plan for renewable energy or energy efficiency.

The 2019 Title 24 Building Energy Efficiency Standards include provisions applicable to all buildings, which are mandatory requirements for efficiency and design. The project would be consistent with the requirements of Title 24 through implementation of energy -reduction measures, such as energy efficient lighting and appliances, water efficient appliances and plumbing fixture, water efficient landscaping and irrigation, and the onsite generation of renewable solar energy, as described above.

Therefore, the project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency and the impact would be less than significant.
