1.0 INTRODUCTION
This report documents the results of an Air Quality and Greenhouse Gas (GHG) Emissions Assessment completed for the Mills Crossing Project (Project), which proposes the construction of a community center with a health and wellness center, a parking structure, arts center and theater, a multifamily and singlefamily housing development, commercial and retail businesses, and community and event centers. This assessment was prepared using methodologies and assumptions recommended in the rules and regulations of the Sacramento Metropolitan Air Quality Management District (SMAQMD). Regional and local existing conditions are presented, along with pertinent emissions standards and regulations. The purpose of this assessment is to estimate Project-generated criteria air pollutants and GHG emissions attributable to the Project and to determine the level of impact the Project would have on the surrounding environment.

1.1 Project Location and Description
The Project Site is a 9.85-acre property located at the corner of Folsom Boulevard and La Loma Drive in the City of Rancho Cordova, Sacramento County, and encompasses the following Assessor’s Parcel Numbers (APNs): 076-0020-019, -20, -21, -22. The Proposed Project Area is roughly bounded by Folsom Boulevard to the south, La Loma Drive to the west, El Caprice Drive to the east, and residential housing to the north fronting Malaga Way and Ashbury Court. Surrounding land uses includes the residential uses to the north, residential uses and Folsom Lake College/Rancho Cordova Civic Center to the east, light industrial uses to the south, and commercial and residential uses to the west. The Mather Field/Mills Train Station is located directly across Folsom Boulevard from the Project Site and can be accessed via a pedestrian crosswalk with stop-traffic control. Additionally, the site is fronted by a Class II bike lane on Folsom Boulevard.

The Project Site is located within the Folsom Boulevard Specific Plan area. The Folsom Boulevard Specific Plan (FBSP or Specific Plan) is the primary planning tool the City uses to guide future development and redevelopment within the Specific Plan area. It seeks to increase the density of both housing and commercial activity; increase pedestrian, bicycle, and transit trips to, from, and through the area; increase the visibility of the corridor as a destination; and change the dynamic and image to that of a high demand, thriving urban area. The site is zoned Residential Mixed-Use – Folsom Boulevard Specific Plan (RMU [FBSP]).

The RMU (FBSP) Zoning District is intended to designate property for the development of medium and high-density housing (between 6.1 and 40 dwelling units per acre) that may incorporate office and/or commercial services. While the predominant use of the development is residential, the City encourages the vertical and/or horizontal integration of commercial and/or office uses that are compatible with the residential development.

The Project Site has a City of Rancho Cordova General Plan land use designation of Residential Mixed-Use (FB-RMU).

The Project proposes a mix of land uses as follows:

Community-Commercial Buildings
The community-commercial buildings would include up to 140,000 square feet of uses, and would include the following:

2.0 AIR QUALITY

2.1 Air Quality Setting
Air quality in a region is determined by its topography, meteorology, and existing air pollutant sources.

These factors are discussed below, along with the current regulatory structure that applies to the Sacramento Valley Air Basin (SVAB), which encompasses the Project Site, pursuant to the regulatory authority of the SMAQMD.

Ambient air quality is commonly characterized by climate conditions, the meteorological influences on air quality, and the quantity and type of pollutants released. The air basin is subject to a combination of topographical and climatic factors that reduce the potential for high levels of regional and local air pollutants. The following section describes the pertinent characteristics of the air basin and provides an overview of the physical conditions affecting pollutant dispersion in the Project Area.

2.1.1 Sacramento Valley Air Basin
The California Air Resources Board CARB divides the State into air basins that share similar meteorological and topographical features. The Project site lies in the SVAB, which is comprised all of Butte, Colusa, Sacramento, Shasta, Sutter, Tehama, Yolo, and Yuba counties and parts of Solano and Placer County. The air basin is relatively flat, bordered by mountains to the east, west, and north and by the San Joaquin Valley to the south. Air flows into the SVAB through the Carquinez Strait, moving across the Sacramento Delta, and bringing pollutants from the heavily populated San Francisco Bay Area. The climate is characterized by hot, dry summers and cool, rainy winters. Characteristic of SVAB winter weather are periods of dense and persistent low-level fog, which are most prevalent between storm systems. From May to October, the region’s intense heat and sunlight lead to high ozone pollutant concentrations. Summer inversions are strong and frequent but are less troublesome than those that occur in the fall. Autumn inversions, formed by warm air subsiding in a region of high pressure, have accompanying light winds that do not provide adequate dispersion of air pollutants.

2.1.1.1 Meteorological Influences on Air Quality
Regional flow patterns affect air quality patterns by directing pollutants downwind of sources. Localized meteorological conditions, such as moderate winds, disperse pollutants and reduce pollutant concentrations. However, the mountains surrounding the SVAB can create a barrier to airflow, which can trap air pollutants in the valley when meteorological conditions are right and a temperature inversion exists.

The highest frequency of air stagnation occurs in the autumn and early winter when large high-pressure cells lie over the valley. The lack of surface wind during these periods and the reduced vertical air flow caused by less surface heating reduces the influx of outside air and allows air pollutants to become concentrated in a stable volume of air. The surface concentrations of pollutants are highest when these conditions are combined with smoke from agricultural burning or when temperature inversions trap cool air, fog, and pollutants near the ground.

Mills Crossing Project 5 June 2023 2023-009
The ozone season (May through October) in the valley is characterized by stagnant morning air or light winds, with the delta sea breeze arriving in the afternoon out of the southwest. Usually, the evening breeze transports the airborne pollutants to the north out of the valley. During about half of the days from July to September, however, a phenomenon called the Schultz Eddy prevents this from occurring. Instead of allowing the prevailing wind patterns to move north and carry the pollutants out of the valley, the Schultz Eddy causes the wind pattern to circle back south. This phenomenon exacerbates the pollution levels in the area and increases the likelihood of exceeding federal or state standards.

2.1.2 Criteria Air Pollutants
Criteria air pollutants are defined as those pollutants for which the federal and state governments have established air quality standards for outdoor or ambient concentrations to protect public health with a determined margin of safety. Ozone (O3), coarse particulate matter (PM10), and fine particulate matter (PM2.5) are generally considered to be regional pollutants because they or their precursors affect air quality on a regional scale. Pollutants such as carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2) are considered to be local pollutants because they tend to accumulate in the air locally. PM is also considered a local pollutant. Health effects commonly associated with criteria pollutants are summarized in Table 2-1.

2.1.2.1 Carbon Monoxide
CO in the urban environment is associated primarily with the incomplete combustion of fossil fuels in motor vehicles. CO combines with hemoglobin in the bloodstream and reduces the amount of oxygen that can be circulated through the body. High CO concentrations can cause headaches, aggravate cardiovascular disease and impair central nervous system functions. CO concentrations can vary greatly over comparatively short distances. Relatively high concentrations of CO are typically found near crowded intersections and along heavy roadways with slow moving traffic. Even under the most severe meteorological and traffic conditions, high concentrations of CO are limited to locations within relatively short distances of the source.

Overall CO emissions are decreasing as a result of the Federal Motor Vehicle Control Program, which has mandated increasingly lower emission levels for vehicles manufactured since 1973. CO levels in the SVAB are in compliance with the state and federal one- and eight-hour standards.

2.1.2.2 Nitrogen Oxides
Nitrogen gas comprises about 80 percent of the air and is naturally occurring. At high temperatures and under certain conditions, nitrogen can combine with oxygen to form several different gaseous compounds collectively called nitric oxides (NOx). Motor vehicle emissions are the main source of NOx in urban areas.

NOx is very toxic to animals and humans because of its ability to form nitric acid with water in the eyes, lungs, mucus membrane, and skin. In animals, long-term exposure to NOx increases susceptibility to respiratory infections, and lowering resistance to such diseases as pneumonia and influenza. Laboratory studies show that susceptible humans, such as asthmatics, who are exposed to high concentrations can suffer from lung irritation or possible lung damage. Precursors of NOx, such as NO and NO2, attribute to the formation of O3 and PM2.5. Epidemiological studies have also shown associations between NO2 concentrations and daily mortality from respiratory and cardiovascular causes and with hospital admissions for respiratory conditions.

2.1.2.3 Ozone
O3 is a secondary pollutant, meaning it is not directly emitted. It is formed when volatile organic compounds (VOCs) or ROGs and NOx undergo photochemical reactions that occur only in the presence of sunlight. The primary source of ROG emissions is unburned hydrocarbons in motor vehicle and other internal combustion engine exhaust. NOx forms as a result of the combustion process, most notably due to the operation of motor vehicles. Sunlight and hot weather cause ground-level O3 to form. Ground-level O3 is the primary constituent of smog. Because O3 formation occurs over extended periods of time, both O3 and its precursors are transported by wind and high O3 concentrations can occur in areas well away from sources of its constituent pollutants.

People with lung disease, children, older adults, and people who are active can be affected when O3 levels exceed ambient air quality standards. Numerous scientific studies have linked ground-level O3 exposure to a variety of problems including lung irritation, difficult breathing, permanent lung damage to those with repeated exposure, and respiratory illnesses.

2.1.2.4 Particulate Matter
PM includes both aerosols and solid particulates of a wide range of sizes and composition. Of concern are those particles smaller than or equal to 10 microns in diameter size (PM10) and small than or equal to 2.5 microns in diameter (PM2.5). Smaller particulates are of greater concern because they can penetrate deeper into the lungs than larger particles. PM10 is generally emitted directly as a result of mechanical processes that crush or grind larger particles or form the resuspension of dust, typically through construction activities and vehicular travel. PM10 generally settles out of the atmosphere rapidly and is not readily transported over large distances. PM2.5 is directly emitted in combustion exhaust and is formed in atmospheric reactions between various gaseous pollutants, including NOx, sulfur oxides (SOx) and VOCs. PM2.5 can remain suspended in the atmosphere for days and/or weeks and can be transported long distances.

The principal health effects of airborne PM are on the respiratory system. Short-term exposure of high PM2.5 and PM10 levels are associated with premature mortality and increased hospital admissions and emergency room visits. Long-term exposure is associated with premature mortality and chronic respiratory disease.

According to the U.S. Environmental Protection Agency (USEPA), some people are much more sensitive than others to breathing PM10 and PM2.5. People with influenza, chronic respiratory and cardiovascular diseases, and the elderly may suffer worse illnesses; people with bronchitis can expect aggravated symptoms; and children may experience decline in lung function due to breathing in PM10 and PM2.5. Other groups considered sensitive include smokers and people who cannot breathe well through their noses. Exercising athletes are also considered sensitive because many breathe through their mouths.

2.1.3 Toxic Air Contaminants
In addition to the criteria pollutants discussed above, toxic air contaminants (TACs) are another group of pollutants of concern. TACs are considered either carcinogenic or noncarcinogenic based on the nature of the health effects associated with exposure to the pollutant. For regulatory purposes, carcinogenic TACs are assumed to have no safe threshold below which health impacts would not occur, and cancer risk is 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.

There are many different types of TACs, with varying degrees of toxicity. Sources of TACs include industrial processes such as petroleum refining and chrome plating operations, commercial operations such as gasoline stations and dry cleaners, and motor vehicle exhaust. Public exposure to TACs can result from emissions from normal operations, as well as from accidental releases of hazardous materials during upset conditions. The health effects of TACs include cancer, birth defects, neurological damage, and death.

Most recently, CARB identified diesel particulate matter (DPM) as a TAC. DPM differs from other TACs in that it is not a single substance but rather a complex mixture of hundreds of substances. Diesel exhaust is a complex mixture of particles and gases produced when an engine burns diesel fuel. DPM is a concern because it causes lung cancer; many compounds found in diesel exhaust are carcinogenic. DPM includes the particle-phase constituents in diesel exhaust. The chemical composition and particle sizes of DPM vary between different engine types (heavy-duty, light-duty), engine operating conditions (idle, accelerate, decelerate), fuel formulations (high/low sulfur fuel), and the year of the engine (USEPA 2002). Some shortterm (acute) effects of diesel exhaust include eye, nose, throat, and lung irritation, and diesel exhaust can cause coughs, headaches, light-headedness, and nausea. DPM poses the greatest health risk among the TACs; due to their extremely small size, these particles can be inhaled and eventually trapped in the bronchial and alveolar regions of the lung.

2.1.4 Ambient Air Quality
Ambient air quality at the Project Site can be inferred from ambient air quality measurements conducted at nearby air quality monitoring stations. CARB maintains more than 60 monitoring stations throughout California. O3, PM10 and PM2.5 are the pollutant species most potently affecting the Project region. As described in detail below, the region is designated as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3 and PM10 (CARB 2022b). The Sacramento – Branch Center #2 air monitoring station (3847 Branch Cener Road, Sacramento), located ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project
ECORP Consulting Inc.

Mills Crossing Project 9 June 2023 2023-009
approximately 2.7 miles southwest of the Project Site, monitors ambient concentrations of PM10. The Sacramento-Del Paso Manor air monitoring station (2701 Avalon Drive, Sacramento), located approximately

3.5 miles northwest of the Project Site, monitors ambient concentrations of O3 and PM2.5. Ambient emissions concentrations vary due to localized variation in emissions sources and climate conditions, but the concentrations from this air quality monitoring station should be considered “generally” representative of ambient concentrations in the Project Area.

Table 2-2 summarizes the published data concerning O3, PM2.5 and PM10 from the Sacramento – Branch Cener #2 monitoring station and the Sacramento-Del Paso Manor monitoring station. O3, PM10 and PM2.5 are the pollutant species most potently affecting the Project region.

The USEPA and CARB designate air basins or portions of air basins and counties as being in “attainment” or “nonattainment” for each of the criteria pollutants. Areas that do not meet the standards are classified as nonattainment areas. The National Ambient Air Quality Standards (NAAQS) (other than O3, PM10 and PM2.5 and those based on annual averages or arithmetic mean) are not to be exceeded more than once per year. The NAAQS for O3, PM10, and PM2.5 are based on statistical calculations over one- to three-year ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project

periods, depending on the pollutant. The California Ambient Air Quality Standards (CAAQS) are not to be exceeded during a three-year period. The attainment status for the Sacramento County portion of the SVAB, which encompasses the Project Site, is included in Table 2-3.

Table 2-3. Attainment Status of Criteria Pollutants in the Sacramento County Portion of the SVAB Pollutant State Designation Federal Designation

PM10 Nonattainment Attainment
PM2.5 Attainment Nonattainment
CO Attainment Unclassified/Attainment
NO2 Attainment Unclassified/Attainment
SO2 Attainment Unclassified/Attainment
Source: CARB 2022b
The determination of whether an area meets the state and federal standards is based on air quality monitoring data. Some areas are unclassified, which means there is insufficient monitoring data for determining attainment or nonattainment. Unclassified areas are typically treated as being in attainment.

Because the attainment/nonattainment designation is pollutant-specific, an area may be classified as nonattainment for one pollutant and attainment for another. Similarly, because the state and federal standards differ, an area could be classified as attainment for the federal standards of a pollutant and as nonattainment for the state standards of the same pollutant. The region is designated as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3 and PM10 (CARB 2022b).

2.1.5 Sensitive Receptors
Sensitive receptors are defined as facilities or land uses that include members of the population who are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses.

Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis. The nearest sensitive receptors to the Project Site include residences directly adjacent to the west, north, and east.

2.2 Regulatory Framework

2.2.1 Federal

2.2.1.1 Clean Air Act
The Clean Air Act (CAA) of 1970 and the CAA Amendments of 1971 required the USEPA to establish the NAAQS, with states retaining the option to adopt more stringent standards or to include other specific pollutants.

These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those “sensitive receptors” most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise. Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed.

The USEPA has classified air basins (or portions thereof) as being in attainment, nonattainment, or unclassified for each criteria air pollutant, based on whether or not the NAAQS have been achieved. If an area is designated unclassified, it is because inadequate air quality data were available as a basis for a nonattainment or attainment designation. Table 2-3 lists the federal attainment status of the SVAB for the criteria pollutants.

2.2.2 State

2.2.2.1 California Clean Air Act
The California Clean Air Act (CCAA) allows the State to adopt ambient air quality standards and other regulations provided that they are at least as stringent as federal standards. CARB, a part of the California Environmental Protection Agency, is responsible for the coordination and administration of both federal and state air pollution control programs within California, including setting the CAAQS. CARB also conducts research, compiles emission inventories, develops suggested control measures, and provides oversight of local programs. CARB establishes emissions standards for motor vehicles sold in California, consumer products (such as hairspray, aerosol paints, and barbecue lighter fluid), and various types of commercial equipment. It also sets fuel specifications to further reduce vehicular emissions. CARB also has primary responsibility for the development of California’s State Implementation Plan (SIP), for which it works closely with the federal government and the local air districts.

2.2.2.2 California State Implementation Plan
The federal CAA (and its subsequent amendments) requires each state to prepare an air quality control plan referred to as the SIP. The SIP is a living document that is periodically modified to reflect the latest emissions inventories, plans, and rules and regulations of air basins as reported by the agencies with jurisdiction over them. The CAA Amendments dictate that states containing areas violating the NAAQS revise their SIPs to ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project
ECORP Consulting Inc.

Mills Crossing Project 12 June 2023 2023-009
include extra control measures to reduce air pollution. The SIP includes strategies and control measures to attain the NAAQS by deadlines established by the CAA. The USEPA has the responsibility to review all SIPs to determine if they conform to the requirements of the CAA.

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 then forwards SIP revisions to the USEPA for approval and publication in the Federal Register. To comply with California law, the SMAQMD has rolled out a series of air quality plans and reports that constitute the SIP for the Sacramento County portion of the SVAB. The most recent report, the 2021 Sacramento County Second 10- Year PM10 Maintenance Plan as a comprehensive strategy to update emission inventories, demonstrates maintenance efforts and updated control measures, and establishes new motor vehicle emission budgets.

Additional plans include the SMAQMD 2017 Sacramento Regional 2008 8-Hour Ozone Attainment and Reasonable Further Progress Plan (including 2018 updates) and the PM2.5 Implementation/Maintenance Plan and Re-designation Request for Sacramento PM2.5 Nonattainment Area (2013). These air quality planning documents present comprehensive strategies to reduce the O3 precursor pollutants (ROG and NOx) as well as PM emissions from stationary, area, mobile, and indirect sources.

2.2.2.3 Tanner Air Toxics Act & Air Toxics “Hot Spots” Information and Assessment Act CARB’s statewide comprehensive air toxics program was established in 1983 with Assembly Bill (AB) 1807, the Toxic Air Contaminant Identification and Control Act (Tanner Air Toxics Act of 1983). AB 1807 created California's program to reduce exposure to air toxics and sets forth a formal procedure for CARB to designate substances as TACs. Once a TAC is identified, CARB adopts an airborne toxics control measure (ATCM) for sources that emit designated TACs. If there is a safe threshold for a substance at which there is no toxic effect, the control measure must reduce exposure to below that threshold. If there is no safe threshold, the measure must incorporate toxics best available control technology to minimize emissions.

CARB also administers the State’s mobile source emissions control program and oversees air quality programs established by state statute, such as AB 2588, the Air Toxics “Hot Spots” Information and Assessment Act of 1987. Under AB 2588, TAC emissions from individual facilities are quantified and prioritized by the air quality management district or air pollution control district. High priority facilities are required to perform a health risk assessment (HRA) and, if specific thresholds are exceeded, required to communicate the results to the public in the form of notices and public meetings. In September 1992, the "Hot Spots" Act was amended by SB 1731, which required facilities that pose a significant health risk to the community to reduce their risk through a risk management plan.

2.2.3 Local

2.2.3.1 Sacramento Metropolitan Air Quality Management District The SMAQMD is the air pollution control agency for Sacramento County, including the Project Site. The agency’s primary responsibility is ensuring that the NAAQS and CAAQS are attained and maintained in the Sacramento County portion of the SVAB. The SMAQMD coordinates the work of government agencies, businesses, and private citizens to achieve and maintain healthy air quality for the Sacramento area. The ITEM 11.1. ATTACHMENT 3

SMAQMD develops market-based programs to reduce emissions associated with mobile sources, processes permits, ensures compliance with permit conditions and with SMAQMD rules and regulations, and conducts long-term planning related to air quality. The SMAQMD is also responsible for adopting and enforcing rules and regulations concerning air pollutant sources, issuing permits for stationary sources of air pollutants, inspecting stationary sources of air pollutants, responding to citizen complaints, monitoring ambient air quality and meteorological conditions, awarding grants to reduce motor vehicle emissions, and conducting public education campaigns, as well as many other activities.

The following is a list of noteworthy SMAQMD rules that are required of construction activities associated with the Proposed Project:
 Rule 201: General Permit Requirements. Any project that includes the use of equipment capable of releasing emissions to the atmosphere may require permit(s) from SMAQMD prior to equipment operation. The applicant, developer, or operator of a project that includes an emergency generator, boiler, or heater should contact the SMAQMD early to determine if a permit is required, and to begin the permit application process. Other general types of uses that require a permit include, but are not limited to, dry cleaners, gasoline stations, spray booths, and operations that generate airborne particulate emissions. Portable construction equipment (e.g. generators, compressors, pile drivers, lighting equipment, etc.) with an internal combustion engine over 50 horsepower is required to have a SMAQMD permit or a CARB portable equipment registration (PERP).  Rule 402: Nuisance. The purpose of this rule is to limit emissions which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or the public, or which endanger the comfort, repose, health, or safety of any such persons or the public, or which cause or have natural tendency to cause injury or damage to business or property.  Rule 403: Fugitive Dust. The purpose of this rule is to require that reasonable precautions be taken so as not to cause or allow the emissions of fugitive dust from non-combustion sources from being airborne beyond the property line from which the emission originates.  Rule 442: Architectural Coatings. The purpose of this rule is to limit the emissions of volatile organic compounds from the use of architectural coatings supplied, sold, offered for sale, applied, solicited for application, or manufactured for use within the SMAQMD.

2.3 Air Quality Emissions Impact Assessment

2.3.1 Thresholds of Significance
The impact analysis provided below is based on the following California Environmental Quality Act (CEQA) Guidelines Appendix G thresholds of significance. The Project would result in a significant impact to air quality if it would do any of the following:
1) Conflict with or obstruct implementation of any applicable air quality plan.

ITEM 11.1. ATTACHMENT 3

2) Result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors). 3) Expose sensitive receptors to substantial pollutant concentrations. 4) Result in other emissions (such as those leading to odors adversely affecting a substantial number of people).

2.3.1.1 Sacramento Metropolitan Air Quality Management District Thresholds The significance criteria established by the applicable air quality management or air pollution control district (SMAQMD) may be relied upon to make the above determinations. According to the SMAQMD, an air quality impact is considered significant if the Proposed Project would violate any ambient air quality standard, contribute substantially to an existing or projected air quality violation, or expose sensitive receptors to substantial pollutant concentrations. The SMAQMD has established thresholds of significance for air quality for construction and operational activities of land use development projects such as that proposed, as shown in Table 2-4.

By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size, by itself, to result in nonattainment of ambient air quality standards. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project’s individual emissions exceed its identified significance thresholds, the project would be cumulatively considerable. Projects that do not exceed any significance thresholds would not be considered cumulative considerable.

2.3.2 Methodology
Air quality impacts were assessed in accordance with methodologies recommended by the SMAQMD.

Where criteria air pollutant quantification was required, emissions were modeled using the California Emissions Estimator Model (CalEEMod), version 2022.1. CalEEMod is a statewide land use emissions computer model designed to quantify potential criteria pollutant emissions associated with both construction and operations from a variety of land use projects. Project construction-generated air pollutant emissions were calculated primarily using CalEEMod model defaults for Sacramento County, though the timing of construction was adjusted to reflect the anticipated construction schedule of 2024 through 2029.

Operational air pollutant emissions were based on the land use mix identified in Section 1.0 of this report and traffic trip generation rates provided by DKS Associates (2023). Two design features attributable to the Project are accounted for in the emissions modeling calculations, specifically the Project’s proximity to transit and its number of affordable/below-market residential units.

2.3.3 Impact Analysis Impact Analysis

2.3.3.1 Project Construction-Generated Criteria Air Quality Emissions Construction Significance Analysis
Construction-generated emissions are temporary and short-term but have the potential to represent a significant air quality impact. Three basic sources of short-term emissions will be generated through construction of the Proposed Project: operation of the construction vehicles (i.e., excavators, trenchers, dump trucks), the creation of fugitive dust during clearing and grading, and the use of asphalt or other oilbased substances during paving activities. Construction activities such as excavation and grading operations, construction vehicle traffic, and wind blowing over exposed soils would generate exhaust emissions and fugitive PM emissions that affect local air quality at various times during construction. Effects would be variable depending on the weather, soil conditions, the amount of activity taking place, and the nature of dust control efforts. The dry climate of the area during the summer months creates a high potential for dust generation.

Construction-generated emissions associated with the Proposed Project were calculated using the CARBapproved CalEEMod computer program, which is designed to model emissions for land use development projects, based on typical construction requirements. See Attachment A for more information regarding the construction assumptions, including construction equipment and duration, used in this analysis.

Construction activities would be subject to mitigation measure AQ-1 (presented below), which would implement the SMAQMD’s Basic Construction Emission Control Practices, known as Best Management ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project
ECORP Consulting Inc.

Mills Crossing Project 16 June 2023 2023-009
Practices (BMPs) during the Project’s construction. The application of AQ-1 ensures that the construction of the Project will not have significant air quality impacts.

Predicted maximum daily construction-generated emissions for the Proposed Project are summarized in Table 2-5. Construction-generated emissions are short-term and of temporary duration, lasting only as long as construction activities occur, but would be considered a significant air quality impact if the volume of pollutants generated exceeds the SMAQMD’s thresholds of significance.

As shown in Table 2-5, emissions generated during Project construction would not exceed the SMAQMD’s daily or annual thresholds of significance with the implementation of mitigation measure AQ-1. This mitigation measure ensures that the SMAQMD’s BACT/BMPs are implemented; which, according to air district regulations, allows the particulate matter significance threshold to be non-zero (allowing PM10 to be 80 pounds/day or 14.6 tons/year and PM2.5 to be 82 pounds/day or 15 tons/year). Without the implementation of AQ-1, the Project’s construction emissions would be over the threshold of 0 pounds/day and thus have a significant effect. The City of Rancho Cordova General Plan: Air Quality Element, Policy AQ.1.2 1 promotes the thresholds and standards set out by the SMAQMD and ensures the enforcement of the air pollution control measures during construction periods. Specifically, Policy AQ.1.2.1 requires the evaluation of projects for compliance with SMAQMD thresholds of significance. With AQ-1, criteria pollutant emissions generated during Project construction would not result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard, and no health effects from Project criteria pollutants would occur.

AQ-1: Implement SMAQMD Basic and Enhanced Construction Emission Control Practices to Reduce Fugitive Dust.

The implementing agency will require the construction contractor(s) to implement basic and enhanced control measures to reduce construction-related fugitive dust as a standard or specification of their contract. The following measures are required for the entirety of the construction area. The implementing agency will ensure, through contract provisions and specifications, that the contractor adheres to the mitigation measures before and during construction and documents compliance with the adopted mitigation measures.  Control of fugitive dust is required by District Rule 403 and enforced by District staff.  Water all exposed surfaces two times daily. Exposed surfaces include, but are not limited to soil piles, graded areas, unpaved parking areas, staging areas, and access roads.
 Cover or maintain at least two feet of free board space on haul trucks transporting soil, sand, or other loose material on the site. Any haul trucks that would be traveling along freeways or major roadways should be covered.
 Use wet power vacuum street sweepers to remove any visible trackout mud or dirt onto adjacent public roads at least once a day. Use of dry power sweeping is prohibited.
 Limit vehicle speeds on unpaved roads to 15 miles per hour (mph).  All roadways, driveways, sidewalks, parking lots to be paved should be completed as soon as possible. In addition, building pads should be laid as soon as possible after grading unless seeding or soil binders are used.
 Minimize idling time either by shutting equipment off when not in use or reducing the time of idling to 5 minutes [California Code of Regulations, Title 13, sections 2449(d)(3) ITEM 11.1. ATTACHMENT 3

and 2485]. Provide clear signage that posts this requirement for workers at the entrances to the site.
 Provide current certificate(s) of compliance for CARB’s In-Use Off-Road Diesel-Fueled Fleets Regulation [California Code of Regulations, Title 13, sections 2449 and 2449.1].  Maintain all construction equipment in proper working condition according to manufacturer’s specifications. The equipment must be checked by a certified mechanic and determine to be running in proper condition before it is operated.

2.3.3.2 Project Operation-Generated Criteria Air Quality Emissions Operational Significance Analysis
Implementation of the Project would result in long-term operational emissions of criteria air pollutants such as PM10, PM2.5, CO, and SO2 as well as O3 precursors such as ROGs and NOX. Project-generated increases in emissions would be predominantly associated with motor vehicle use. As previously described, operational air pollutant emissions were based on the land use mix identified in Section 1.0 of this report and traffic trip generation rates from Nelson/Nygaard (2023). Long-terms operational emissions attributable to the Project are identified in Table 2-6 and compared to the operational significance thresholds promulgated by the SMAQMD. The PM10 and PM2.5 non-zero thresholds are reliant on the implementation of the SMAQMD’s BACT/BMPs for land use development project operations. The following are the recommendations made by the SMAQMD for land use development project operations:
 Compliance with District rules that control operational PM and NOx emissions. Reference rules regarding wood burning devices, boilers, water heaters, generators and other PM control rules that may apply to equipment to be located at the project.
 Compliance with mandatory measures in the California Building Energy Efficiency Standards (Title 24, Part 6) that pertain to efficient use of energy at a residential or a non-residential land use.  Compliance with mandatory measures in the California Green Building Code (Title 24, Part 11).

Current mandatory measures related to operational PM include requirements for bicycle parking, parking for fuel efficient vehicles, electric vehicle charging, and fireplaces for non-residential projects. Residential project measures include requirements for electric vehicle charging and fireplaces.

The Proposed Project will comply with the above recommendations in order to justify the use of a nonzero operational threshold for PM10 and PM2.5. As seen by Table 2-6, the air pollutant concentrations are below the SMAQMD significance threshold for the Project.

As shown in Table 2-6, the Project’s emissions would not exceed any SMAQMD thresholds for any criteria air pollutants during operation.

As identified in Table 2-3, the Sacramento County portion of the SVAB is listed as a nonattainment area for federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3, and PM10 (CARB 2022b). O3 is a health threat to persons who already suffer from respiratory diseases and can cause severe ear, nose and throat irritation and increases susceptibility to respiratory infections. PM can adversely ITEM 11.1. ATTACHMENT 3

affect the human respiratory system. As shown in Table 2-6, the Proposed Project would result in increased emissions of the O3 precursor pollutants ROG and NOx, PM10, and PM2.5, however, the correlation between a project’s emissions and increases in nonattainment days, or frequency or severity of related illnesses, cannot be accurately quantified. The overall strategy for reducing air pollution and related health effects in the SMAQMD is contained in the SMAQMD 2017 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan (2018), 2021 Sacramento County Second 10-Year PM10 Maintenance Plan, and PM2.5 Implementation/Maintenance Plan and Re-designation Request for Sacramento PM2.5 Nonattainment Area (2013). These air quality planning documents present comprehensive strategies to reduce the O3 precursor pollutants (ROG and NOx) as well as PM emissions from stationary, area, mobile, and indirect sources. Each of these air quality planning documents provide control measures that reduce emissions to attain and maintain federal ambient air quality standards such as the application of available cleaner technologies, best management practices, incentive programs, as well as development and implementation of zero and near-zero technologies and control methods. The CEQA thresholds of significance established by the SMAQMD are designed to meet the objectives of these air quality planning documents and in doing so achieve and maintain attainment status with state and federal standards. As noted above, the Project would increase the emission of certain pollutants, but would not exceed the thresholds of significance established by the SMAQMD for purposes of reducing air pollution and its deleterious health effects.

2.3.3.3 Project Consistency with Air Quality Planning
As part of its enforcement responsibilities, the USEPA requires each state with nonattainment areas to prepare and submit a SIP that demonstrates the means to attain the federal standards. The SIP must integrate federal, state, and local plan components and regulations to identify specific measures to reduce pollution in nonattainment areas, using a combination of performance standards and market-based programs. Similarly, under state law, the CCAA requires an air quality attainment plan to be prepared for areas designated as nonattainment with regard to the NAAQS and CAAQS. Air quality attainment plans outline emissions limits and control measures to achieve and maintain these standards by the earliest practical date.

As previously mentioned, the Project Site is located within the SVAB, which is under the jurisdiction of the SMAQMD. SMAQMD is required, pursuant to the federal CAA, to reduce emissions of criteria pollutants for which the SVAB is in nonattainment. The SMAQMD is required to submit air quality plans and rate-ofprogress milestone evaluations in accordance with the federal Clean Air Act. The SMAQMD air quality attainment plans and reports, which include the 2017 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan (2018), 2021 Sacramento County Second 10-Year PM10 Maintenance Plan, and PM2.5 Implementation/Maintenance Plan and Re-designation Request for Sacramento PM2.5 Nonattainment Area (2013), present comprehensive strategies to reduce the O3 precursor pollutants (ROG and NOx) as well as PM emissions from stationary, area, mobile, and indirect sources.

A project is consistent with regional air quality planning efforts in part if it is consistent with the population and housing assumptions that were used in the development of the SMAQMD air quality plans and does nothing to inhibit the region’s achievement of air quality standards. Growth projections in the City of Rancho ITEM 11.1. ATTACHMENT 3

Cordova are based largely on the City of Rancho Cordova General Plan. As such, projects that propose development consistent with the growth anticipated by the General Plan would generally be consistent with the SMAQMD regional air quality planning efforts. The Project Site is located within the Folsom Boulevard Specific Plan area and has a City of Rancho Cordova General Plan land use designation of Residential MixedUse (FB-RMU). The site is zoned Residential Mixed-Use – Folsom Boulevard Specific Plan (RMU [FBSP]). The Folsom Boulevard Specific is the primary planning tool the City uses to guide future development and redevelopment within the Specific Plan area. It seeks to increase the density of both housing and commercial activity; increase pedestrian, bicycle, and transit trips to, from, and through the area; increase the visibility of the corridor as a destination; and change the dynamic and image to that of a high demand, thriving urban area. The RMU (FBSP) Zoning District is intended to designate property for the development of medium and high-density housing (between 6.1 and 40 dwelling units per acre) that may incorporate office and/or commercial services. While the predominant use of the development is residential, the City encourages the vertical and/or horizontal integration of commercial and/or office uses that are compatible with the residential development. The Project proposes a mix of uses onsite by developing residential, commercial, and recreational uses on infill and underutilized parcels. As such, the Project is consistent with the City’s General Plan, Folsom Boulevard Specific Plan, and City Zoning Code and is therefore consistent with the types, intensity, and patterns of land use envisioned for the site. Furthermore, as shown in Tables 2-5 and 2-6, all Project emissions would fall below SMAQMD significance thresholds. For these reasons the Project would not conflict with SMAQMD’s air quality planning.

It is additionally noted that the Project is considered “infill development” as it proposes to redevelop a previously developed property and enhance the physical design of the urban environment. Under Public Resources Code (PRC) section 21061.3, an “infill site” is defined as a site that “has been previously developed for qualified urban uses.” In turn, a “qualified urban use” is defined, pursuant to PRC section 21072, as “a residential, commercial, or public institutional, transit or transportation passenger facility, or retail use, or any combination of those uses.” Additionally, the Project Site is located in an “urbanized area,” which is defined under PRC section 21071 as “an incorporated city” that meets the criteria of having a population of at least 100,000 persons. These aspects of the Project would result in the generation of a reduced amount of criteria air pollutant emissions. According to the USEPA, redevelopments (namely at brownfield sites such as the Project Site) produce 32 to 57 percent less emissions per capita relative to conventional developments (USEPA 2011); this is because the number of daily vehicle trips and daily vehicle miles traveled (VMT) associated with the redevelopment tend to be lower compared with development on vacant land.

The Proposed Project would be located in close proximity to the Mather Field/Mills Train Station, which is directly across Folsom Boulevard from the Project Site and can be accessed via a pedestrian crosswalk with stop-traffic control. The public transit accessibility would result in fewer vehicle trips and VMT compared to the statewide average and encourage walking and non-automotive forms of transportation, thus resulting in the reduction of, or no increase in, transportation-related emissions, a primary goal of SMAQMD air quality planning. Furthermore, the site is fronted by a Class II bike lane on Folsom Boulevard.

The Project Site can be identified for its “location efficiency.” Location efficiency describes the location of the Project relative to the type of urban landscape its proposed to fit within, such as an “urban area,” “compact infill,” or “suburban center.” The Project Site represents an urban/compact infill location within an ITEM 11.1. ATTACHMENT 3

area of the city developed with residential and commercial uses. The Project Site is served by existing public transportation as previously described; it is within an active urban center surrounded with many existing offsite office, commercial, and residential buildings. The Project would locate additional residential land uses in close proximity to existing offsite office, commercial, and residential uses. Therefore, the Project would provide future Project residents with potential work opportunities and commercial service options in close proximity to the site. Additionally, the Project would locate potential employment opportunities for residents already living in the vicinity. The location efficiency of the Project Site would result in synergistic benefits that would reduce vehicle trips and VMT compared to the statewide average and would result in corresponding reduction of transportation related air pollutant emissions, a primary goal of SMAQMD air quality planning.

The Project would increase housing density in the vicinity over current conditions. Increased density reduces emissions associated with transportation as it reduces the distance people travel for work or services and provides a foundation for the implementation of other strategies to reduce emissions, a primary goal of SMAQMD air quality planning.

2.3.3.4 Exposure of Sensitive Receptors to Toxic Air Contaminants As previously described, sensitive receptors are defined as facilities or land uses that include members of the population that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses. Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over age 65, children under age 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis. The nearest sensitive receptors to the Project Site include residences directly adjacent to the west, north, and east.

Construction-Generated Air Contaminants
Construction-related activities would result in temporary, short-term Proposed Project-generated emissions of DPM, ROG, NOx, CO, and PM10 from the exhaust of off-road, heavy-duty diesel equipment for site preparation (e.g., clearing, grading); soil hauling truck traffic; paving; and other miscellaneous activities. The Sacramento County portion of the SVAB is listed as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3 and PM10. Thus, existing O3, PM10 and PM2.5 levels in the SVAB are at unhealthy levels during certain periods. However, as shown in Table 2-5 the Project would not exceed the SMAQMD significance thresholds for construction emissions.

The health effects associated with O3 are generally associated with reduced lung function. Because the Project would not involve construction activities that would result in O3 precursor emissions (ROG or NOx) in excess of the SMAQMD thresholds, the Project is not anticipated to substantially contribute to regional O3 concentrations and the associated health impacts.

CO tends to be a localized impact associated with congested intersections. In terms of adverse health effects, CO competes with oxygen, often replacing it in the blood, reducing the blood’s ability to transport oxygen to vital organs. The results of excess CO exposure can include dizziness, fatigue, and impairment of central nervous system functions. The Project would not involve construction activities that would result in ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project
ECORP Consulting Inc.

Mills Crossing Project 24 June 2023 2023-009
CO emissions in excess of the SMAQMD thresholds. Thus, the Project’s CO emissions would not contribute to the health effects associated with this pollutant.

Particulate matter (PM10 and PM2.5) contains microscopic solids or liquid droplets that are so small that they can get deep into the lungs and cause serious health problems. Particulate matter exposure has been linked to a variety of problems, including premature death in people with heart or lung disease, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function, and increased respiratory symptoms such as irritation of the airways, coughing, or difficulty breathing. For construction activity, DPM is the primary TAC of concern. PM10 exhaust is considered a surrogate for DPM as all diesel exhaust is considered to be DPM and PM10 contains PM2.5 as a subset. As with O3 and NOx, the Project would not generate emissions of PM10 or PM2.5 that would exceed the SMAQMD’s thresholds. Accordingly, the Project’s PM10 and PM2.5 emissions are not expected to cause any increase in related regional health effects for these pollutants.

In summary, Project construction would not result in a potentially significant contribution to regional concentrations of nonattainment pollutants and would not result in a significant contribution to the adverse health impacts associated with those pollutants.

Operational Air Contaminants
Operation of the Proposed Project would not result in the development of any substantial sources of air toxics. There are no stationary sources associated with the operations of the Project; nor would the Project attract additional mobile sources that spend long periods queuing and idling at the site. Onsite Project emissions would not result in significant concentrations of pollutants at nearby sensitive receptors. The Project would not have a high carcinogenic or non-carcinogenic risk during operation.

Carbon Monoxide Hot Spots
It has long been recognized that CO exceedances are caused by vehicular emissions, primarily when idling at intersections. Concentrations of CO are a direct function of the number of vehicles, length of delay, and traffic flow conditions. Under certain meteorological conditions, CO concentrations close to congested intersections that experience high levels of traffic and elevated background concentrations may reach unhealthy levels, affecting nearby sensitive receptors. Given the high traffic volume potential, areas of high CO concentrations, or “hot spots,” are typically associated with intersections that are projected to operate at unacceptable levels of service during the peak commute hours. It has long been recognized that CO hotspots are caused by vehicular emissions, primarily when idling at congested intersections. However, transport of this criteria pollutant is extremely limited, and CO disperses rapidly with distance from the source under normal meteorological conditions. Furthermore, vehicle emissions standards have become increasingly more stringent in the last 20 years. Currently, the allowable CO emissions standard in California is a maximum of 3.4 grams/mile for passenger cars (there are requirements for certain vehicles that are more stringent). With the turnover of older vehicles, introduction of cleaner fuels, and implementation of increasingly sophisticated and efficient emissions control technologies, CO concentration in the Sacramento County portion of the SVAB is designated as in attainment. Detailed modeling of Project-specific CO “hot spots” is not necessary and thus this potential impact is addressed qualitatively.

A CO “hot spot” would occur if an exceedance of the state one-hour standard of 20 parts per million (ppm) or the eight-hour standard of 9 ppm were to occur. The analysis prepared for CO attainment in the South Coast Air Quality Management District’s (SCAQMD’s) 1992 Federal Attainment Plan for Carbon Monoxide in Los Angeles County and a Modeling and Attainment Demonstration prepared by the SCAQMD as part of the 2003 AQMP can be used to demonstrate the potential for CO exceedances of these standards. The SCAQMD is the air pollution control officer for much of southern California. The SCAQMD conducted a CO hot spot analysis as part of the 1992 CO Federal Attainment Plan at four busy intersections in Los Angeles County during the peak morning and afternoon time periods. The intersections evaluated included Long Beach Boulevard and Imperial Highway (Lynwood), Wilshire Boulevard and Veteran Avenue (Westwood), Sunset Boulevard and Highland Avenue (Hollywood), and La Cienega Boulevard and Century Boulevard (Inglewood). The busiest intersection evaluated was at Wilshire Boulevard and Veteran Avenue, which has a traffic volume of approximately 100,000 vehicles per day. Despite this level of traffic, the CO analysis concluded that there was no violation of CO standards (SCAQMD 1992). In order to establish a more accurate record of baseline CO concentrations affecting the Los Angeles, a CO “hot spot” analysis was conducted in 2003 at the same four busy intersections in Los Angeles at the peak morning and afternoon time periods. This “hot spot” analysis did not predict any violation of CO standards. The highest one-hour concentration was measured at 4.6 ppm at Wilshire Boulevard and Veteran Avenue and the highest eighthour concentration was measured at 8.4 ppm at Long Beach Boulevard and Imperial Highway. Thus, there was no violation of CO standards.

Similar considerations are also employed by other Air Districts when evaluating potential CO concentration impacts. More specifically, the Bay Area Air Quality Management District (BAAQMD), the air pollution control officer for the San Francisco Bay Area, concludes that under existing and future vehicle emission rates, a given project would have to increase traffic volumes at a single intersection by more than 44,000 vehicles per hour or 24,000 vehicles per hour where vertical and/or horizontal air does not mix—in order to generate a significant CO impact.

The Proposed Project is anticipated to result in 4,354 daily traffic trips (DKS Associates 2023). Thus, the Proposed Project would not generate traffic volumes at any intersection of more than 100,000 vehicles per day (or 44,000 vehicles per day) and there is no likelihood of the Project traffic exceeding CO values.

2.3.3.5 Odors
Typically, odors are regarded as an annoyance rather than a health hazard. However, manifestations of a person’s reaction to foul odors can range from psychological (e.g., irritation, anger, or anxiety) to physiological (e.g., circulatory and respiratory effects, nausea, vomiting, and headache).

With respect to odors, the human nose is the sole sensing device. The ability to detect odors varies considerably among the population and overall is quite subjective. Some individuals have the ability to smell minute quantities of specific substances; others may not have the same sensitivity but may have sensitivities to odors of other substances. In addition, people may have different reactions to the same odor; in fact, an odor that is offensive to one person (e.g., from a fast-food restaurant) may be perfectly acceptable to another. It is also important to note that an unfamiliar odor is more easily detected and is more likely to cause complaints than a familiar one. This is because of the phenomenon known as odor fatigue, in which ITEM 11.1. ATTACHMENT 3

ECORP Consulting Inc.

Mills Crossing Project 26 June 2023 2023-009
a person can become desensitized to almost any odor and recognition only occurs with an alteration in the intensity.

Quality and intensity are two properties present in any odor. The quality of an odor indicates the nature of the smell experience. For instance, if a person describes an odor as flowery or sweet, then the person is describing the quality of the odor. Intensity refers to the strength of the odor. For example, a person may use the word “strong” to describe the intensity of an odor. Odor intensity depends on the odorant concentration in the air. When an odorous sample is progressively diluted, the odorant concentration decreases. As this occurs, the odor intensity weakens and eventually becomes so low that the detection or recognition of the odor is quite difficult. At some point during dilution, the concentration of the odorant reaches a detection threshold. An odorant concentration below the detection threshold means that the concentration in the air is not detectable by the average human.

During construction, the Proposed Project presents the potential for generation of objectionable odors in the form of diesel exhaust in the immediate vicinity of the site. However, these emissions are short-term in nature and will rapidly dissipate and be diluted by the atmosphere downwind of the emission sources.

Additionally, odors would be localized and generally confined to the construction area. Therefore, construction odors would not adversely affect a substantial number of people to odor emissions.

According to the SMAQMD, land uses commonly considered to be potential sources of obnoxious odorous emissions include wastewater treatment plants, sanitary landfills, composting/green waste facilities, recycling facilities, petroleum refineries, chemical manufacturing plants, painting/coating operations, rendering plants, and food packaging plants. The Proposed Project does not include any uses identified by the SMAQMD as being associated with odors.

3.0 GREENHOUSE GAS EMISSIONS

3.1 Greenhouse Gas Setting
Certain gases in the earth’s atmosphere, classified as GHGs, play a critical role in determining the earth’s surface temperature. Solar radiation enters the earth’s atmosphere from space. A portion of the radiation is absorbed by the earth’s surface and a smaller portion of this radiation is reflected back toward space. This absorbed radiation is then emitted from the earth as low-frequency infrared radiation. The frequencies at which bodies emit radiation are proportional to temperature. Because the earth has a much lower temperature than the sun, it emits lower-frequency radiation. Most solar radiation passes through GHGs; however, infrared radiation is absorbed by these gases. As a result, radiation that otherwise would have escaped back into space is instead trapped, resulting in a warming of the atmosphere. This phenomenon, known as the greenhouse effect, is responsible for maintaining a habitable climate on earth. Without the greenhouse effect, the earth would not be able to support life as we know it.

Prominent GHGs contributing to the greenhouse effect are CO2, methane (CH4), and N2O. Fluorinated gases also make up a small fraction of the GHGs that contribute to climate change. Fluorinated gases include chlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride; however, it is noted that these gases are not associated with typical land use development. Human-caused emissions of these GHGs in excess of natural ambient concentrations are believed to be responsible for intensifying the greenhouse effect and leading to a trend of unnatural warming of the earth’s climate, known as global climate change or global warming. It is “extremely likely” that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in GHG concentrations and other anthropogenic factors together (Intergovernmental Panel on Climate Change [IPCC] 2014).

Table 3-1 describes the primary GHGs attributed to global climate change, including their physical properties, primary sources, and contributions to the greenhouse effect.

Each GHG differs in its ability to absorb heat in the atmosphere based on the lifetime, or persistence, of the gas molecule in the atmosphere. CH4 traps over 25 times more heat per molecule than CO2, and N2O absorbs 298 times more heat per molecule than CO2 (IPCC 2014). Often, estimates of GHG emissions are presented in carbon dioxide equivalents (CO2e), which weight each gas by its global warming potential.

Expressing GHG emissions in CO2e takes the contribution of all GHG emissions to the greenhouse effect and converts them to a single unit equivalent to the effect that would occur if only CO2 were being emitted.

Climate change is a global problem. GHGs are global pollutants, unlike criteria air pollutants and TACs, which are pollutants of regional and local concern. Whereas pollutants with localized air quality effects have relatively short atmospheric lifetimes (about one day), GHGs have long atmospheric lifetimes (one to several thousand years). GHGs persist in the atmosphere for long enough time periods to be dispersed around the globe. Although the exact lifetime of any particular GHG molecule is dependent on multiple variables and cannot be pinpointed, it is understood that more CO2 is emitted into the atmosphere than is sequestered by ocean uptake, vegetation, or other forms. Of the total annual human-caused CO2 emissions, approximately 55 percent is sequestered through ocean and land uptakes every year, averaged over the ITEM 11.1. ATTACHMENT 3

last 50 years, whereas the remaining 45 percent of human-caused CO2 emissions remains stored in the atmosphere (IPCC 2013).

Table 3-1. Greenhouse Gases
Greenhouse Gas Description
CO2 Carbon dioxide is a colorless, odorless gas. CO2 is emitted in a number of ways, both naturally and through human activities. The largest source of CO2 emissions globally is the combustion of fossil fuels such as coal, oil, and gas in power plants, automobiles, industrial facilities, and other sources. A number of specialized industrial production processes and product uses such as mineral production, metal production, and the use of petroleum-based products can also lead to CO2 emissions. The atmospheric lifetime of CO2 is variable because it is so readily exchanged in the atmosphere.1

CH4 Methane is a colorless, odorless gas and is the major component of natural gas, about 87 percent by volume. It is also formed and released to the atmosphere by biological processes occurring in anaerobic environments. Methane is emitted from a variety of both human-related and natural sources. Human-related sources include fossil fuel production, animal husbandry (intestinal fermentation in livestock and manure management), rice cultivation, biomass burning, and waste management.

These activities release significant quantities of CH4 to the atmosphere. Natural sources of CH4 include wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, and other sources such as wildfires. The atmospheric lifetime of CH4 is about12 years.2

N2O Nitrous oxide is a clear, colorless gas with a slightly sweet odor. Nitrous oxide is produced by both natural and human-related sources. Primary human-related sources of N2O are agricultural soil management, animal manure management, sewage treatment, mobile and stationary combustion of fossil fuels, adipic acid production, and nitric acid production. N2O is also produced naturally from a wide variety of biological sources in soil and water, particularly microbial action in wet tropical forests. The atmospheric lifetime of N2O is approximately 120 years.3

The quantity of GHGs that it takes to ultimately result in climate change is not precisely known; it is sufficient to say the quantity is enormous, and no single project alone would measurably contribute to a noticeable incremental change in the global average temperature or to global, local, or microclimates. From the standpoint of CEQA, GHG impacts to global climate change are inherently cumulative.

3.1.1 Sources of Greenhouse Gas Emissions
In 2022, CARB released the 2022 edition of the California GHG inventory covering calendar year 2020 emissions. In 2020, California emitted 369.2 million gross metric tons of CO2e including from imported electricity. Combustion of fossil fuel in the transportation sector was the single largest source of California’s GHG emissions in 2020, accounting for approximately 38 percent of total GHG emissions in the state.

Continuing the downward trend from previous years, transportation emissions decreased 27 million metric ITEM 11.1. ATTACHMENT 3

tons of CO2e in 2020, though the intensity of this decrease was most likely from light duty vehicles after shelter-in-place orders were enacted in response to the COVID-19 pandemic. Emissions from the electricity sector account for 16 percent of the inventory and have remained at a similar level as in 2019 despite a 44 percent decrease in in-state hydropower generation (due to below average precipitation levels), which was more than compensated for by a 10 percent growth in in-state solar generation and cleaner imported electricity incentivized by California’s clean energy policies. California’s industrial sector accounts for the second largest source of the state’s GHG emissions in 2020, accounting for 23 percent (CARB 2022c).

3.2 Regulatory Framework

3.2.1 State

3.2.1.1 Executive Order S-3-05
Executive Order (EO) S-3-05, signed by Governor Arnold Schwarzenegger in 2005, proclaims that California is vulnerable to the impacts of climate change. It declares that increased temperatures could reduce the Sierra Nevada snowpack, further exacerbate California’s air quality problems, and potentially cause a rise in sea levels. To combat those concerns, the EO established total GHG emission targets for the state.

Specifically, emissions are to be reduced to the 2000 level by 2010, the 1990 level by 2020, and to 80 percent below the 1990 level by 2050.

3.2.1.2 Assembly Bill 32 Climate Change Scoping Plan and Updates In 2006, the California legislature passed Assembly Bill (AB) 32 (Health and Safety Code § 38500 et seq., or AB 32), also known as the Global Warming Solutions Act. AB 32 required CARB to design and implement feasible and cost-effective emission limits, regulations, and other measures, such that statewide GHG emissions are reduced to 1990 levels by 2020 (representing a 25 percent reduction in emissions). Pursuant to AB 32, CARB adopted a Scoping Plan in December 2008, which outlined measures to meet the 2020 GHG reduction goals. California exceeded the target of reducing GHG emissions to 1990 levels by the year 2017.

The Scoping Plan is required by AB 32 to be updated at least every five years. The latest update, the 2017 Scoping Plan Update, addresses the 2030 target established by Senate Bill (SB) 32 as discussed below and establishes a proposed framework of action for California to meet a 40 percent reduction in GHG emissions by 2030 compared to 1990 levels. The key programs that the Scoping Plan Update builds on include increasing the use of renewable energy in the State, the Cap-and-Trade Regulation, the Low Carbon Fuel Standard, and reduction of methane emissions from agricultural and other wastes.

3.2.1.3 Senate Bill 32 and Assembly Bill 197 of 2016
In August 2016, Governor Brown signed SB 32 and AB 197, which serve to extend California’s GHG reduction programs beyond 2020. SB 32 amended the Health and Safety Code to include § 38566, which contains language to authorize CARB to achieve a statewide GHG emission reduction of at least 40 percent below 1990 levels by no later than December 31, 2030.

ITEM 11.1. ATTACHMENT 3

3.2.1.4 Senate Bill X1-2 of 2011, Senate Bill 350 of 2015, and Senate Bill 100 of 2018 In 2018, SB 100 was signed codifying a goal of 60 percent renewable procurement by 2030 and 100 percent by 2045 Renewables Portfolio Standard.

3.2.1.5 Senate Bill 375
The Sustainable Communities and Climate Protection Act of 2008, which became effective in January 2009, helps facilitate AB 32’s GHG reduction goals by addressing the emissions from passenger vehicles. The main objectives of the bill aim to reduce GHG emissions through extensive transportation, housing, and land use planning. SB 375 directs CARB to establish regional targets to reduce GHG emissions from passenger vehicle use. CARB administers 2035 targets for each of the regions throughout the State. The corresponding metropolitan planning organizations (MPOs) in each region are required to prepare and adopt a Sustainable Communities Strategy (SCS) that helps to adhere to the CARB administered targets. Sustainable Community Strategies play a vital role in regional transportation plans by allowing transportation, land use, and housing strategies to align with the State’s GHG emission goals. Project Plans that are consistent with their region’s SCS may be subject to a more streamlined CEQA process.

3.2.1.6 2022 Building Energy Efficiency Standards for Residential and Nonresidential Buildings
The Building and Efficiency Standards (Energy Standards) were first adopted and put into effect in 1978 and have been updated periodically in the intervening years. These standards are a unique California asset that have placed the State on the forefront of energy efficiency, sustainability, energy independence and climate change issues. The 2022 California Building Codes include provisions related to energy efficiency to reduce energy consumption and greenhouse gas emissions from buildings. Some of the key energy efficiency components of the codes are:

1. Energy Performance Requirements: The codes specify minimum energy performance standards for the building envelope, lighting, heating and cooling systems, and other components.

2. Lighting Efficiency: The codes require that lighting systems meet minimum efficiency standards, such as the use of energy-efficient light bulbs and fixtures.

3. HVAC Systems: The codes establish requirements for heating, ventilation, and air conditioning (HVAC) systems, including the use of high-efficiency equipment, duct sealing, and controls.

4. Building Envelope: The codes include provisions for insulation, air sealing, glazing, and other building envelope components to reduce energy loss and improve indoor comfort.

5. Renewable Energy: The codes encourage the use of renewable energy systems, such as photovoltaic panels and wind turbines, to reduce dependence on non-renewable energy sources.

6. Commissioning: The codes require the commissioning of building energy systems to ensure that they are installed and operate correctly and efficiently.

ITEM 11.1. ATTACHMENT 3

Overall, the energy efficiency provisions of the 2022 California Building Codes aim to reduce the energy consumption of buildings, lower energy costs for building owners and occupants, and reduce the environmental impact of the built environment. The 2022 Building Energy Efficiency Standards improve upon the 2019 Energy Standards for new construction of, and additions and alterations to, residential and nonresidential buildings. The exact amount by which the 2022 Building Codes are more efficient compared to the 2019 Building Codes would depend on the specific provisions that have been updated and the specific building being considered. However, in general, the 2022 Building Codes have been updated to include increased requirements for energy efficiency, such as higher insulation and air sealing standards, which are intended to result in more efficient buildings. The 2022 standards are a major step toward meeting Zero Net Energy.

3.2.2 Local

3.2.2.1 Sacramento Metropolitan Air Quality Management District To provide guidance to local lead agencies on determining significance for GHG emissions in CEQA documents, SMAQMD has established operational GHG reduction thresholds, as well as constructionrelated thresholds. The GHG targets and reduction recommendations made by the SMAQMD have taken into considerations reports and guidelines from various state agencies and organizations, such as the California Air Pollution Control Officers Association CEQA & Climate Change guidelines, the CARB Scoping Plan, the California Natural Resource Agency’s CEQA Guidelines, and other reputable sources. In February 2021, the SMAQMD revised the Greenhouse Gas Emissions Chapter within their CEQA Guide.

The SMAQMD has both construction and operational thresholds for GHG emissions within their CEQA Guide. Their construction thresholds establish a bright line threshold of 1,100 metric tons/year. Similarly, SMAQMD recommends a comparison of a project’s annual operational GHG emissions to a significance threshold of 1,100 metric tons per year, though coupled with implementation of SMAQMD Tier 1 Best Management Practices (BMPs). Specifically, if a project’s annual operational GHG emissions are calculated to fall under 1,100 metric tons and the project implements all SMAQMD Tier 1 BMPs, GHG-related impacts would be less than significant. If the threshold is exceeded, or in the case the project does not implement the Tier 1 BMPs, then the project may have a cumulatively considerable contribution to a significant cumulative environmental impact.

The Tier 1 BMPs are:
 BMP 1 – projects shall be designed and constructed without natural gas infrastructure; and  BMP 2 - projects shall meet the current CalGreen Tier 2 standards1, except all electric vehicle capable spaces shall instead be electric vehicle ready.
1 CalGreen contains voluntary "Tier 1" and "Tier 2" standards that are not mandatory statewide but could be required by a City or County. These are 'reach' standards, related to energy efficiency, that can be adopted by local jurisdictions and may be incorporated as mandatory standards in future code cycles.

ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project
ECORP Consulting Inc.

Mills Crossing Project 32 June 2023 2023-009
If Tier 1 BMPs are not fully implemented then emissions, including natural gas emissions, should be estimated and the project should mitigate any natural gas emissions and require all prewiring necessary so that the building is ready for a future retrofit to all-electric (e.g., such that electric space heating, water heating, drying, and cooking appliances could be installed). If emissions still exceed 1,100 metric tons of CO2e per year, then the project must implement SMAQMD’s Tier 2 BMP 3:
 Office projects must achieve a 15 percent reduction in VMT per worker compared to the existing average VMT per capita for the County.
 Residential projects must achieve a 15 percent reduction in VMT per resident compared to the existing average VMT per capita in the County.
 Retail projects must achieve no net increase in total VMT.

If the project achieves BMP 3, then the operational impact is considered less than significant, and no further analysis is needed. If a project cannot incorporate the required BMPs, other reductions or purchasing and retiring GHG/carbon offsets from a registry approved by the SMAQMD may be required. Carbon offsets are instruments that can be bought, sold, and traded. Like a stock or equity that represents a unit of ownership in a company, a carbon offset represents a unit of GHG emissions reductions. Each offset is essentially a certification that a certain quantity of GHG emissions has been avoided, prevented, or sequestered. Offset registries that the SMAQMD may approve have developed a broad consensus around the standards that are necessary to ensure that offsets are environmentally sound, namely, that offsets be real, permanent, quantifiable, verifiable, enforceable, and additional. Approved registries may include but are not limited to any of the following: (i) the Climate Action Reserve, the American Carbon Registry and Verra, which are all approved by CARB; (ii) any entity approved at any time by CARB to act as an “offset project registry” under the state’s cap-and-trade program; (iii) other regulatory or voluntary credits that demonstrate, based on substantial evidence, that the offsets are real, permanent, quantifiable, verifiable, enforceable, and additional.

3.2.2.2 Sacramento Metropolitan Air Quality Management District The Sacramento Area Council of Government’s (SACOG’s) Metropolitan Transportation Plan/Sustainable Communities Strategy 2020 (MTP/SCS) is the latest update of a long-range policy and planning program that establishes GHG emissions goals for automobiles and light-duty trucks for and the year 2035, and thus establishes an overall GHG target for the region beyond 2020 applicable to these subsectors of the transportation sector. CARB assigned SACOG a 19 percent GHG reduction target from 2005 levels by 2035.

The GHG reduction target is the percent reduction in passenger vehicle GHG emission per capita, compared to Year 2005. This change represents a reduction from just over 23 pounds per capita on a given weekday in 2005, to just under 19 pounds by 2035 (SACOG 2020).

3.2.2.3 City of Rancho Cordova Climate Action and Adaptation Plan The City of Rancho Cordova has drafted the City Climate Action and Adaptation Plan (CAAP), which at the time of this analysis was in the public review process and therefore not yet adopted. The CAAP is intended to serve as a comprehensive roadmap to community sustainability and resilience in the city. The purposes ITEM 11.1. ATTACHMENT 3

Air Quality and Greenhouse Gas Emissions Assessment for the Mills Crossing Project
ECORP Consulting Inc.

Mills Crossing Project 33 June 2023 2023-009
of the CAAP are to identify strategies and measures the City can take to reduce GHG emissions to levels that align with the State of California’s goals and set forth strategies to adapt and promote resilience to the impacts of climate change. In drafting the CAAP, the City evaluated the volume of emissions generated in a baseline year (2019) and identified City-specific targets and goals that determine the amount of community-wide emissions that need to be reduced in Rancho Cordova to align with statewide GHG reduction targets for 2030 and 2045. The City then developed GHG reduction measures to achieve the City’s 2030 target and make substantial progress towards the City’s 2045 goal. Additionally, in preparation of the CAAP, the City conducted a climate change vulnerability assessment to better understand its vulnerability to climate hazards. This was then used to inform and develop a set of adaptation strategies, objectives, and actions to improve community resilience in the context of climate change. The successful implementation and administration of the CAAP would reduce emissions and reduce climate related risks in the city, as well as provide other co-benefits like strengthening the city’s economy, improving risk management, cleaning the environment, and improving the health and wellness of residents.

The CAAP provides new development project applicants in the city the opportunity to use CEQA streamlining tools for projects that are consistent with the CAAP. Demonstrating consistency with the CAAP establishes that a project will not result in an “additional environmental effect” related to GHG emissions. A project’s consistency with the CAAP will be determined through a Consistency Checklist (“Checklist”). The Checklist, which has yet to be made available at the time of this analysis, will contain GHG reduction measures applicable to development projects that are required to be implemented on a project-by-project basis to achieve the City’s 2030 reduction target and make substantial progress toward the 2045 goal. Once the CAAP is adopted, new development projects will need to incorporate all potentially applicable Plan measures to demonstrate consistency with the CAAP. By incorporating applicable GHG reduction measures in the Checklist into project designs or conditions of approval, the City will ensure that new development is consistent with applicable GHG reduction measures in the CAAP and will contribute its “fair share” in achieving the identified GHG reduction targets. Projects that do not demonstrate consistency may, at the City’s discretion, prepare a more comprehensive project-specific analysis of GHG emissions consistent with CEQA requirements.

3.3 Greenhouse Gas Emissions Impact Assessment

3.3.1 Thresholds of Significance
The impact analysis provided below is based on the following CEQA Guidelines Appendix G thresholds of significance. The Project would result in a significant impact to greenhouse gas emissions if it would:
1) Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment.
2) Conflict with any applicable plan, policy, or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases or
The Appendix G thresholds for GHG emissions do not prescribe specific methodologies for performing an assessment, do not establish specific thresholds of significance, and do not mandate specific mitigation ITEM 11.1. ATTACHMENT 3

measures. Rather, the CEQA Guidelines emphasize the lead agency’s discretion to determine the appropriate methodologies and thresholds of significance consistent with the manner in which other impact areas are handled in CEQA. With respect to GHG emissions, the CEQA Guidelines Section 15064.4(a) states that lead agencies “shall make a good-faith effort, based to the extent possible on scientific and factual data, to describe, calculate or estimate” GHG emissions resulting from a project. The CEQA Guidelines note that an agency has the discretion to either quantify a project’s GHG emissions or rely on a “qualitative analysis or other performance-based standards.” (14 CCR 15064.4(b)). A lead agency may use a “model or methodology” to estimate GHG emissions and has the discretion to select the model or methodology it considers “most appropriate to enable decision makers to intelligently take into account the project’s incremental contribution to climate change.” (14 CCR 15064.4(c)). Section 15064.4(b) provides that the lead agency should consider the following when determining the significance of impacts from GHG emissions on the environment:

1. The extent a project may increase or reduce GHG emissions as compared to the existing environmental setting.

2. Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project.

3. The extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions (14 CCR 15064.4(b)).

In addition, Section 15064.7(c) of the CEQA Guidelines specifies that “[w]hen adopting or using thresholds of significance, a lead agency may consider thresholds of significance previously adopted or recommended by other public agencies, or recommended by experts, provided the decision of the lead agency to adopt such thresholds is supported by substantial evidence” (14 CCR 15064.7(c)). The CEQA Guidelines also clarify that the effects of GHG emissions are cumulative and should be analyzed in the context of CEQA’s requirements for cumulative impact analysis (see CEQA Guidelines Section 15130). As a note, the CEQA Guidelines were amended in response to Senate Bill 97. In particular, the CEQA Guidelines were amended to specify that compliance with a GHG emissions reduction plan renders a cumulative impact insignificant.

Per CEQA Guidelines Section 15064(h)(3), a project’s incremental contribution to a cumulative impact can be found not cumulatively considerable if the project would comply with an approved plan or mitigation program that provides specific requirements that would avoid or substantially lessen the cumulative problem within the geographic area of the project. To qualify, such plans or programs must be specified in law or adopted by the public agency with jurisdiction over the affected resources through a public review process to implement, interpret, or make specific the law enforced or administered by the public agency.

Examples of such programs include a “water quality control plan, air quality attainment or maintenance plan, integrated waste management plan, habitat conservation plan, natural community conservation plans [and] plans or regulations for the reduction of greenhouse gas emissions.” Put another way, CEQA Guidelines Section 15064(h)(3) allows a lead agency to make a finding of less than significant for GHG emissions if a project complies with adopted programs, plans, policies and/or other regulatory strategies to reduce GHG emissions.

The local air quality agency regulating the SVAB is the SMAQMD, the regional air pollution control officer for the basin. As previously stated, to provide guidance to local lead agencies on determining significance for GHG emissions in CEQA documents, SMAQMD has set thresholds and required BMPs to implement throughout the Project construction and operations. The numeric bright line thresholds and BMPs described in Section 3.2.2.1 above were developed to be consistent with CEQA requirements for developing significance thresholds, are supported by substantial evidence, and provide guidance to CEQA practitioners and lead agencies with regard to determining whether GHG emissions from a proposed project are significant.

The significance of the Project’s GHG emissions is evaluated consistent with CEQA Guidelines Section 15064.4(b)(2) by considering whether the Project complies with applicable plans, policies, regulations and requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions. The City Rancho Cordova may set a project-specific threshold based on the context of each particular project, including using the SMAQMD expert recommendation. For the Proposed Project, the SMAQMD’s 1,100 metric tons of CO2e per year threshold and implementation of SMAQMD BMPs are used as the significance threshold for the Project. Additionally, the Project is assessed for consistency with SACOG’s MTP/SCS. As previously described, the MTP/SCS is the latest update of a long-range policy and planning program that establishes GHG emissions goals for automobiles and light-duty trucks for the year 2035, and thus establishes an overall GHG target for the region beyond 2020 applicable to these subsectors of the transportation sector. CARB assigned SACOG a 19 percent GHG reduction target from 2005 levels by 2035 (SACOG 2020).

3.3.2 Methodology
GHG impacts were assessed in accordance with methodologies recommended by the SMAQMD. Where GHG emission quantification was required, emissions were modeled using the CalEEMod software, version 2022.1. CalEEMod is a statewide land use emissions computer model designed to quantify potential GHG emissions associated with both construction and operations from a variety of land use projects. Project construction generated GHG emissions were calculated primarily using CalEEMod model defaults for Sacramento County, though the timing of construction was adjusted to reflect the anticipated construction schedule of 2024 through 2029. Operational GHG emissions were based on the land use mix identified in Section 1.0 of this report and traffic trip generation rates provided by Nelson/Nygaard (2023). Two design features attributable to the Project are accounted for in the emissions modeling calculations, specifically the Project’s proximity to transit and its number of affordable/below-market residential units.

3.3.3 Impact Analysis

3.3.3.1 Generation of GHG Emissions
Construction
Construction-related activities that would generate GHG emissions include worker commute trips, haul trucks carrying supplies and materials to and from the Project Site, and off-road construction equipment (e.g., dozers, loaders, excavators). Table 3-2 illustrates the specific construction generated GHG emissions ITEM 11.1. ATTACHMENT 3

that would result from construction of the Project. Once construction is complete, the generation of these GHG emissions would cease.

As shown in Table 3-2, Project construction would result in the maximum generation of 973 metric tons of CO2e over the third calendar year of construction, which is below the SMAQMD significance threshold.

Once construction is complete, the generation of these GHG emissions would cease.

Operational Significance Analysis
Operation of the Project would result in an increase in GHG emissions primarily associated with motor vehicle trips and onsite energy sources. Long-term operational GHG emissions attributed to the Project are identified in Table 3-3.

As previously described, SMAQMD specifies that all projects must adhere to the Tier 1 BMP requirements in order to be considered less than significant. In order to ensure compliance with the SMAQMD guidelines, this Project is subject to mitigation measure GHG-1 (see below), which will ensure that Tier 1 BMPs are implemented. The long-term Project operational GHG emissions identified in Table 3-3 account for SMAQMD Tier 1 BMP 1, which requires that all development be designed and constructed without natural gas infrastructure. Due to limitations in the modeling software, GHG-reductions resulting from Tier 1 BMP 2, which requires projects to meet the current CalGreen Tier 2 standards with the exception that all electric vehicle capable spaces be electric vehicle ready, are unable to be quantified.

Notes: Emission projections are predominately based on the land use mix identified in Section 1.0 of this report and traffic trip generation rates from DKS Associates(2023). SMAQMD Tier 1 BMP 1, which requires that all development be designed and constructed without natural gas infrastructure, is included in the modeling calculations per mitigation measure GHG-1.

As shown in Table 3-3, the Proposed Project’s operational GHG emissions would be approximately 5,268 metric tons of CO2e per year, which exceeds the SMAQMD significance threshold of 1,100 metric tons of CO2e per year. Projects that exceed 1,100 metric tons of CO2e per year after implementation of the Tier 1 BMPs must also implement SMAQMD Tier 2 BMPs. As previously discussed, the SMAQMD’s Tier 2 BMP are as follows:
 Office projects must achieve a 15 percent reduction in VMT per worker compared to the existing average VMT per capita for the County.
 Residential projects must achieve a 15 percent reduction in VMT per resident compared to the existing average VMT per capita in the County.
 Retail projects must achieve no net increase in total VMT.

If the project achieves this SMAQMD Tier 2 BMP, then the operational impact is considered less than significant, and no further analysis is needed. If a project cannot incorporate the required BMPs, other reductions or purchasing and retiring GHG/carbon offsets from a registry approved by the SMAQMD may be required. Carbon offsets are instruments that can be bought, sold, and traded. Like a stock or equity that represents a unit of ownership in a company, a carbon offset represents a unit of GHG emissions reductions.

Each offset is essentially a certification that a certain quantity of GHG emissions has been avoided, prevented, or sequestered. Offset registries that the SMAQMD may approve have developed a broad consensus around the standards that are necessary to ensure that offsets are environmentally sound, namely that offsets be real, permanent, quantifiable, verifiable, enforceable, and additional. Approved ITEM 11.1. ATTACHMENT 3

registries may include but are not limited to any of the following: (i) the Climate Action Reserve, the American Carbon Registry, and Verra, which are all approved by CARB; (ii) any entity approved at any time by CARB to act as an “offset project registry” under the state’s cap-and-trade program; (iii) other regulatory or voluntary credits that demonstrate, based on substantial evidence, that the offsets are real, permanent, quantifiable, verifiable, enforceable, and additional.

Therefore, in addition to mitigation measure GHG-1, mitigation measure GHG-2 is required in order for the Project’s contribution of GHG emissions to be considered less than significant.

Mitigation Measures
GHG-1: Implement SMAQMD Tier 1 Best Management Practices.

The implementing agency will require the Project to implement Sacramento Metropolitan Air Quality Management District Tier 1 Best Management Practices:
 BMP 1 - projects shall be designed and constructed without natural gas infrastructure.  BMP 2 - projects shall meet the current CalGreen Tier 2 standards, except all electric vehicle capable spaces shall instead be electric vehicle ready.

GHG-2: Implement SMAQMD Tier 2 Best Management Practices.

The implementing agency will require the Project to implement Sacramento Metropolitan Air Quality Management District Tier 2 Best Management Practices:
 BMP 3 - The Project applicant shall coordinate with the City of Rancho Cordova to implement feasible transportation demand management (TDM) strategies, which would decrease the vehicle miles traveled generated by the Project as follows:

1. The Project office space component must achieve a 15 percent reduction in VMT per worker compared to the existing average VMT per capita for Sacramento County.

2. The Project residential component must achieve a 15 percent reduction in VMT per resident compared to the existing average VMT per capita in Sacramento County.

3. The Project retail component must achieve no net increase in total VMT.

Examples of potential measures include (but are not limited to): paid parking, employee telecommuting, employee shuttle service, expansion of transit service coverage / subsidized transit fares, enhanced bicycle and pedestrian connections, and flexible work schedules.

In the case that the necessary VMT reductions are infeasible, the purchasing and retiring GHG/carbon offsets from a SMAQMD-approved registry is required. Approved registries may include but are not limited to any of the following: (i) the Climate Action Reserve, the American Carbon Registry and Verra; (ii) any entity approved at any time by the California Air Resources Board to act as an “offset project registry” under the state’s cap-and-trade program; (iii) other ITEM 11.1.

regulatory or voluntary credits that demonstrate, based on substantial evidence, that the offsets are real, permanent, quantifiable, verifiable, enforceable, and additional.

Adherence to both mitigation measures GHG-1 and GHG-2 are required in order for the Project’s contribution of GHG emissions to be considered less than significant.

3.3.3.2 Conflict with any Applicable Plan, Policy, or Regulation of an Agency Adopted for the Purpose of Reducing the Emissions of Greenhouse Gases As previously described, SACOG’s MTP/SCS establishes GHG emissions goals for automobiles and lightduty trucks. As shown in Table 3-3, GHG emissions resulting from Project-related transportation sources are one of the most potent sources of emissions, and therefore comparison to the MTP/SCS is an appropriate indicator of whether the Project is consistent with the MTP/SCS. Since the development site is classified as a “Center and Corridor Community” in the MTP/SCS (SACOG 2020, Appendix D), it is included in an area where urban development is predicted by SACOG. According to the MTP/SCS, land uses in Center and Corridor Communities are typically higher density and more mixed than surrounding land uses. Centers and Corridors are identified in local plans as historic downtowns, main streets, suburban or urban commercial corridors, rail station areas, central business districts, or town centers. They typically have more compact development patterns, a greater mix of uses, and a wider variety of transportation infrastructure compared to the communities surrounding them. Some have frequent transit service, either bus or rail, and all have pedestrian and bicycling infrastructure that is more supportive of walking and bicycling than other Community Types. The Project is consistent with the “Center and Corridor Community” classification in the MTP/SCS, and it can be assumed that regional mobile emissions will decrease in line with the goals of the MTP/SCS with implementation of the future development within the Project Area.
