The purpose of this technical memorandum is to assess the potential air quality and greenhouse gas (GHG) emissions impacts associated with construction and operation of the Reduced Pacific Specific Plan Project Alternative (reduced project). This analysis uses the significance thresholds in Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 CCR 15000 et seq.) and the emissions -based significance thresholds recommended by the San Diego Air Pollution Control District (SDAPCD) and other applicable thresholds of significance. This analysis compares the potential impacts of the reduced project to that which was evaluated in the Air Quality and Greenhouse Gas Emissions Technical Report for the Pacific Project (Dudek report) , dated February 6, 2023 (Dudek 2023) (original project).

Section 1, Project Description, discusses the details of the reduced project design. Section 2, Approach and Methodology, discusses the approach to estimating emissions of criteria air pollutants and GHG emissions during construction and operation of the reduced project. Section 3, Air Quality, describes the thresholds of significance and presents an air quality impact analysis per Appendix G of the CEQA Guidelines. Section 4, Greenhouse Gas Emissions, describes the GHG emissions–related thresholds of significance and presents a GHG emissions impact analysis per Appendix G of the CEQA Guidelines. Section 5, Conclusions, summarizes the findings of the analysis. Section 6, References Cited, includes a list of the references cited in this technical report. 1 Project Description
The approximately 33-acre project site is located in the western portion of the City, at the northwest corner of Las Posas Road and Linda Vista Drive. The 33.2-acre project site is an infill site located in the western portion of the City of San Marcos (City), at the northwest corner of S. Las Posas Road and Linda Vista Drive, comprised of Assessor’s Parcel Numbers 219-222-01, 219-222-02, 219-222-03, and 219-222-04. La Mirada Drive abuts the site’s northern boundary, while South Pacific Street abuts the pro perty’s western boundary. The Grand Plaza shopping center is located directly across Las Posas Road to the east. Light industrial uses are adjacent to the site’s

northern, southern, and western boundary, and Bradley Park is located across from the site’s southwestern corner.

Single- and multi-family residential uses are located to the west and south of Bradley Park.

The reduced project consists of 299 residential units, including a mix of rowhomes, villas, and affordable flats on approximately 13.3 acres of the 33.2 -acre project site. The reduced project includes a total of 646 parking spaces and 111,025 square feet of common open space area. 45 of the 299 total units (15% of the total) would be designated as deed -restricted affordable units (alternatively, the project reserves the option to contribute to the affordable housing fund by paying the in -lieu fee). The reduced project also includes landscaping, bio -retention areas, and circulation improvements. The remaining approximately 19.9 acres of the 33.2 -acre project site would be preserved and restored as open space and habitat area. The reduced project would have a density of approximately 8.99 dwelling units per acre, including the open space and habitat area. Figure 1 shows the locatio n of the reduced project and Figure 2 provides a site plan.

The reduced project proposes a General Plan Amendment, Rezone, Specific Plan, Tentative Map, and Multi - Family Site Development Plan. The General Plan Amendment and Rezone would change the General Plan designation and Zoning from Industrial (I) to Specific Plan Area (SPA). Off-site improvements would be similar to that of the proposed project.

2 Approach and Methodology

2.1 Construction
Construction assumptions, including timing, phasing, and equipment type and quantity, as well as worker and vendor truck trips, were based on information provided by the applicant. Default values provided by the California Emissions Estimator Model (CalEEMod) were used where detailed project information was not available. For purposes of estimating project GHG emissions, it is assumed that construction of the reduced project would commence in June 20261 and would end in November 2027. Construction of the reduced project is anticipated to occur in five phases. Accordingly, five phases consisting of site preparation, grading, building construction, paving, and architectural coating were assumed. The analysis contained herein is based on the following assumptions (the duration of phases is approximate):
▪ Site Preparation: 10 days (June 2026)
▪ Grading: 2 months (June 2026 – July 2026)
▪ Building Construction: 14 months (July 2026 – September 2027) ▪ Paving: 1 month (September 2027 – October 2027)
▪ Architectural Coating: 1 month (October 2027 – November 2027) The construction equipment mix used for estimating construction emissions of the reduced project is based on CalEEMod defaults and is shown in Table 1, Construction Scenario Assumptions. For worker and vendor truck trips, the default CalEEMod assumptions for one-way trips were rounded up to the nearest even number to account for whole round trips. For this analysis, it was generally assumed that heavy construction equipment would operate 5 days a week (22 days per month) during project construction. Grading activities were anticipated to be minimal for the reduced project; therefore, no haul trucks would be required to import or export material. VOC off -gassing emissions result from evaporation of solvents contained in surface coatings, such as in paints and primers used during the architectural coating phase. The VOC emis sions factor is based on the VOC content of the surface coatings. SDAPCD’s Rule 67.0.1 (Architectural Coatings) governs the VOC content for interior and exterior coatings (SDAPCD 2015): internal reapplication architectural coatings would have a VOC content of 50 grams per liter (g/L), and exterior architectural coatings would have a VOC content of 100 g/L.

1 The analysis assumes a construction start date of June 2026, which represents the earliest date construction would initiate (although unlikely). Assuming the earliest start date for construction represents the worst -case scenario for criteria air pollutant emissions because equipment and vehicle emission factors for later years would be slightly less due to more stringent standards for in-use off-road equipment and heavy -duty trucks, as well as fleet turnover replacing older equipment and vehicles in later years.

The reduced project would implement dust control strategies. To reflect implementation of proposed dust control strategies, the following was assumed in CalEEMod in accordance with SDAPCD Rule 55:
▪ Water exposed area two times per day (55% reduction in PM10 and PM2.5). ▪ Limit unpaved road travel to 15 miles per hour.

Health Risk Assessment
As a precautionary measure, a health risk assessment (HRA) was performed to assess the impact of construction on sensitive receptors proximate to the reduced project. This report includes an HRA associated with emissions from construction of the reduced project based on the methodologies prescribed in the Office of Environmental Health Hazard Assessment (OEHHA) Air Toxics Hot Spots Program Risk Assessment Guidelines – Guidance Manual for Preparation of Health Risk Assessments (OEHHA 2015). To implement the OEHHA Guidelines based on Project information, the SDAPCD has developed a three-tiered approach where each successive tier is progressively more refined, with fewer conservative assumptions. The SDAPCD Supplemental Guidelines for Submission of Air Toxics “Hot Spots” Program Health Risk Assessments provides guidance with which to perform HRAs within the SDAB (SDAPCD 2022).

Health effects from carcinogenic air toxics are usually described in terms of cancer risk. The SDAPCD recommends a carcinogenic (cancer) risk threshold of 10 in a million. Additionally, some TACs increase non-cancer health risk

MEMORANDUM
SUBJECT: AIR QUALITY AND GREENHOUSE GAS EMISSIONS TECHNICAL MEMORANDUM FOR THE REDUCED PACIFIC

SPECIFIC PLAN PROJECT ALTERNATIVE

13170 7 FEBRUARY 2024

due to long -term (chronic) exposures. The Chronic Hazard Index is the sum of the individual substance chronic hazard indices for all TACs affecting the same target organ system. The SDAPCD recommends a Chronic Hazard Index significance threshold of 1.0 (project increment). The exhaust from diesel engines is a complex mixture of gases, vapors, and particles, many of which are known human carcinogens. DPM has established cancer risk factors and relative exposure values for long -term chronic health hazard impacts. No short -term, acute relative exposure level has been established for DPM; therefore, acute impacts of DPM are not addressed in this assessment. This HRA evaluated the risk to future residents from diesel emissions from exhaust from onsite construction equipment and diesel haul and vendor trucks.

The dispersion modeling of DPM was performed using the American Meteorological Society/EPA Regulatory Model (AERMOD), which is the model SDAPCD requires for atmospheric dispersion of emissions. AERMOD is a steady - state Gaussian plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of surface and elevated sources, building downwash, and simple and complex terrain (EPA 2015). For the reduced project, AERMOD was run with all sources emitting unit emissions (1 gram per second) to obtain the “Χ/Q” values. Χ/Q is a dispersion factor that is the average effluent concentration normalized by source strength and is used as a way to simplify the representation of emissions from many sources. The Χ/Q values of ground -level concentrations were determined for construction emissions using AERMOD and the maximum concentrations determined for the 1 -hour and Period averaging periods . Principal parameters of this modeling are presented in Table 2.

Table 2. AERMOD Principal Parameters – Reduced Project
Parameter Details
Meteorological Data The latest 3-year meteorological data (2010–2012) for the Escondido Station (Station ID 3177) from SDAPCD were downloaded and then input to AERMOD. For cancer or chronic noncancer risk assessments, the average cancer risk of all years modeled was used.

Urban versus Rural
Option
Urban areas typically have more surface roughness, as well as structures and low- albedo surfaces that absorb more sunlight—and thus more heat—relative to rural areas. However, based on the SDAPCD guidelines, the rural dispersion option was selected due to the reduced project’s proximity to the ocean.

Terrain
Characteristics
The terrain in the vicinity of the modeled project site is generally flat. The elevation of the modeled site is about 545 feet above sea level. Digital elevation model files were imported into AERMOD so that complex terrain features were evaluated as appropriate.

Elevation Data Digital elevation data were imported into AERMOD, and elevations were assigned to the emission sources and receptors. Digital elevation data were obtained through AERMOD View in the United States Geological Survey’s National Elevation Dataset format with a 30-meter resolution.

Emission Sources
and Release
Parameters
Air dispersion modeling of DPM from construction equipment was conducted using emissions estimated using the CalEEMod, assuming emissions would occur 8 hours per day, 5 days per week. The reduced project area was modeled as a series of volume sources.

Source Release
Characterizations
Based on EPA methodology, the modeled line volume sources would result in a release height of 3.4 meters, a plume height of 6.8 meters, and a plume width of

8.6 meters for off-road equipment and diesel trucks (EPA 2015).

Table 2. AERMOD Principal Parameters – Reduced Project
Parameter Details
Discrete Receptors A uniform Cartesian grid overlaying residential receptors in close proximity to the reduced project with 20-meter resolution was placed. Additional discrete receptors were placed over residences not within the uniform Cartesian grid.

Note: See Appendix B.

Dispersion model plotfiles from AERMOD were then imported into CARB’s Hotspots Analysis and Reporting Program Version 2 to determine health risk, which requires peak 1-hour emission rates and annual-averaged emission rates for all pollutants for each modeling source. For the residential health risk, the HRA assumes exposure would start in the third trimester of pregnancy . The results of the HRA are provided in Section 3.2, and detailed results and methodology are provided in Appendix B.

2.2 Operation
Emissions from the operational phase of the reduced project was estimated using CalEEMod. Operational year 2027 was assumed because it would coincide with completion of construction.

Area Sources
The reduced project would generate air quality emissions from area sources. Consumer products are chemically formulated products used by household and institutional consumers, including detergents; cleaning compounds; polishes; floor finishes; cosmetics; personal care products; home, lawn, and garden products; disinfectants; sanitizers; aerosol paints; and automotive specialty products. Other paint products, furniture coatings, or architectural coatings are not considered consumer products (CAPCOA 20 21). The CalEEMod default values for consumer products were modeled.

VOC off-gassing emissions result from evaporation of solvents contained in surface coatings, such as in paints and primers used during building maintenance. CalEEMod calculates the VOC evaporative emissions from application of surface coatings based on the VOC emissions factor, the building square footage, the assumed fraction of surface area, and the reapplication rate. The VOC emission s factor is based on the VOC content of the surface coatings, and SDAPCD’s Rule 67.0.1 (Architectural Coatings) governs th e VOC content for interior and exterior coatings (SDAPCD 2015). The model default reapplication rate of 10% of area per year is assumed. Consistent with CalEEMod defaults, it was assumed that the surface area for painting equals 2.7 times the floor square footage, with 75% assumed for interior coating and 25% assumed for exterior surface coating (CAPCOA 20 21). Consistent with the architectural coatings used during the construction phase, the applicant would use architectural coatings with a VOC content of 5 0 g/L for internal reapplication, and a VOC content of 100 g/L for exterior architectural coatings for any reapplication during operation.

Landscape maintenance includes fuel combustion emissions from equipment such as lawn mowers, rototillers, shredders/grinders, blowers, trimmers, chainsaws, and hedge trimmers. Emissions from landscape equipment use are estimated based on CalEEMod default values for emission factors (grams per square foot of nonresidential building space per day) and number of summer days (when landscape maintenance would generally be performed)

MEMORANDUM

SPECIFIC PLAN PROJECT ALTERNATIVE

13170 9 FEBRUARY 2024

and winter days. Emissions associated with potential landscape maintenance equipment were included to conservatively capture potential project operational emission sources.

No woodstoves or wood burning fireplaces would be included in the reduced project design; therefore, they were not included in the CalEEMod analysis. The reduced project would include natural gas fireplaces and are included in the CalEEMod analysis.

Energy Sources
As represented in CalEEMod, energy sources would include emissions associated with building electricity and natural gas usage. Electricity use would contribute indirectly to criteria air pollutant emissions; however, the emissions from electricity use are only quantified for GHGs in CalEEMod, since criteria pollutant emissions occur at the site of the power plant, which is typically off site.

Operational criteria air pollutant emissions from energy sources include natural gas combustion for appliances and space and water heating. The current Title 24, Part 6 standards, referred to as the 2019 Title 24 Building Energy Efficiency Standards, became effective on January 1, 2020. CalEEMod defaults were assumed for electricity and natural gas.

CalEEMod default energy intensity factors (CO2, CH4, and N2O mass emissions per kilowatt hour) for SDG&E are based on the value for SDG&E’s energy mix in 2021. As explained in Section 3.2.2, SB X1-2 established a target of 33% from renewable energy sources for all electricity providers in California by 2020, and SB 350 calls for further development of renewable energy, with a target of 50% by 2030.

Mobile Sources
The reduced project would generate air quality emissions from mobile sources (vehicular traffic) as a result of the residents of the reduced project. CalEEMod was used to estimate emissions from proposed vehicular sources (refer to Appendix A). The trip generation rates for the reduced project residential land use were adjusted in CalEEMod to match the overall weekday daily trips based on the Traffic Impact Analysis (LLG 2021). CalEEMod default data, trip modes, trip lengths, fleet mix, and emissions factors were used for the model inputs. CalEEMod default vehicle emission factors and vehicle fleet mix for 2027, as based on the CARB EMFAC2017 model, were used to estimate emissions associated with vehicular sources.

Solid Waste
The reduced project would generate solid waste and therefore would result in CO 2e emissions associated with landfill off-gassing. CalEEMod default values were used to estimate GHG emissions associated with solid waste.

Water and Wastewater
Supply, conveyance, treatment, and distribution of water for the reduced project would require the use of electricity, which would result in associated indirect GHG emissions. Similarly, wastewater generated by the reduced project would require the use of electricity for conveyance and treatment, along with GHG emissions generated during wastewater treatment. Water consumption estimates for both indoor and outdoor water use relied on CalEEMod default assumptions.

3 Air Quality Assessment

3.1 Thresholds of Significance
Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) provides guidance for evaluating whether a development project may result in significant impacts. Based on Appendix G of the CEQA Guidelines, the reduced project would have a significant impact on air quality if the reduced project would:

1. Conflict with or obstruct implementation of the applicable air quality plan.

2. Result in a cumulatively considerable net increase of any criteria pollutant for which the reduced project region is nonattainment under an applicable federal or state ambient air quality standard.

3. Expose sensitive receptors to substantial pollutant concentrations.

4. Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) indicates that, where available, the significance criteria established by the applicable air quality management district or pollution control district may be relied upon to determine whether the reduced project would have a significant impact on air quality. As part of its air quality permitting process, the SDAPCD has established thresholds in Rule 20.2 requiring the preparation of Air Quality Impact Assessments for permitted stationary sources. The SDAPCD sets forth quantitative emission thresholds below which a stationary source would not have a significant impact on ambient air quality. Project-related air quality impacts estimated in this environmental analysis would be considered significant if a ny of the a pplicable significance thresholds presented in Table 3 are exceeded.

For CEQA purposes, these screening criteria can be used as numeric methods to demonstrate that a project’s total emissions would not result in a significant impact to air quality.

For nonattainment pollutants, if emissions exceed the thresholds shown in Table 3, the reduced project could have the potential to result in a cumulatively considerable net increase in these pollutants and thus could have a significant impact on ambient air quality. A project that involves a use that would produce objectionable odors would be deemed to have a significant odor impact if it would affect a considerable number of off-site receptors.

3.2 Impact Analysis
Threshold 1: Would the project conflict with or obstruct implementation of the applicable air quality plan? The SDAPCD is responsible for developing and implementing the clean air plans for attainment and maintenance of the ambient air quality standards in the SDAB—specifically, the SIP and RAQS. 2 SANDAG is responsible for developing forecasts and data that are used by the SDAPCD in preparing the SIP and RAQS. The federal O 3 maintenance plan, which is part of the SIP, was adopted in 2012. The SIP includes a demonstration that current strategies and tactics will maintain acceptable air quality in the basin based on the NAAQS. The RAQS was initially adopted in 1991 and is updated every 3 years (most recently in 2022). The RAQS outlines SDAPCD’s plans and control measures designed to attain the state air quality standards for O 3. The SIP and RAQS rely on information from CARB and SANDAG, including mobile and area source emissions , as well as information regarding projected growth in the County as a whole and the cities in San Diego County, to project future emissions and determine the strategies necessary for the reduction of emissions through regulatory controls. CARB mobile source emission projections and SANDAG growth projections are based on population, vehicle trends, and land use plans developed by the County and the cities in the County as part of development of their general plans.

Although the SDAPCD and City do not provide guidance regarding the analysis of impacts associated with air quality plan conformance, the Cou nty’s Guidelines for Determining Significance and Report and Format and Content Requirements – Air Quality does discuss conformance with the RAQS (County of San Diego 2007). The guidance indicates that, if the reduced project, in conjunction with other projects, contributes to growth projections that would not exceed SANDAG’s growth projections for a city, the reduced project would not be in conflict with the RAQS. If a

2 For the purpose of this discussion, the relevant federal air quality plan is the Ozone Maintenance Plan (SDAPCD 2012). The RAQS is the applicable plan for purposes of state air quality planning. Both plans reflect growth projections in the SDAB.

project includes development that is greater than that anticipated in the local plan and SANDAG’s growth projections, the reduced project might be in conflict with the SIP and RAQS and may contribute to a potentially significant cumulative impact on air quality (County of San Diego 2007). The reduced project’s proposed zoning is compared to the existing land use designation on the site and then the reduced project’s growth inducing impacts are compared to those included in the SANDAG’s growth projections for the City.

The reduced project site is currently zoned Industrial (I) with a maximum floor-to-area ratio of 0.50. The floor-to-area ratio means the ratio of gross building area of the development, excluding structured parking areas, proposed for the reduced project divided by the net lot area. According to the City of San Marcos Municipal Code, the Industrial (I) land use zone is intended to “provide a setting for the full range of indoor manufacturing, distribution, warehousing, processing, and general service uses that are adequately served by vehicular arterials and utilities. Industries that use hazardous materials, require heavy equipment, and/or that generate sustained noise levels are deemed appropriate for this Zone, and may be permitted according to the standards of this chapter. The I Zone is intended to implement and be consistent with the Industrial land use designation of the General Plan” (City of San Marcos 2020a).

The reduced project proposes a GPA/Rezone to change the land use from an Industrial (I) to a SPA. This target density would net a maximum of 299 dwelling units. The City projects an increase of 3,170 housing units between 2020 and 2035 (SANDAG 2013), and the reduced project would account for 9% of the projected housing units to increase in the City between 2020 and 2035 in the SANDAG Series 13 forecast. The reduced project would be within the growth projections for the City; thus, the reduced project would result in regional growth that is accounted for within the RAQS. Furthermore, at a regional level, the growth is consistent with the underlying growth forecasts in the SIP and RAQS. Therefore, implementation of the reduced project would not conflict with the RAQS or SIP, and potential future development would be consistent with the growth in the region. The reduced project’s proximity to State Route 78 and the Palomar College Sprinter station and bus station make for ideal connectivity to a regional transportation network, employment centers, and shopping and services. In addition, the reduced project would implement applicable measures in the City’s 2020 CAP Consistency Checklist (see Appendix C), which would result in co -benefits to reducing the reduced project ’s operational air quality emissions by installing electric vehicle charging stations, installing bicycle infrastructure, implementing a Transportation Demand Management Plan, and reducing parking near transit. These measures would further reduce the reduced project’s emissions from vehicle trips, increase access to transit, and encourage alternative modes of transportation. Consistent with the original project, impacts would be less than significant.

Threshold 2: Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? In analyzing cumulative impacts from a project, the analysis must specifically evaluate a project’s contribution to the cumulative increase in pollutants for which the air basin is designated as nonattainment for the CAAQS and NAAQS. If a project does not exceed thresholds and is determined to have less -than-significant project-specific impacts, it may still contribute to a significant cumulative impact on air quality if the emissions from the reduced project, in combination with the emissions from other proposed or reasonably foreseeable future projects, are in excess of established thresholds. However, a project would only be considered to have a significant cumulative impact if the reduced project’s contribution accounts for a significant proportion of the cumulative total emissions (i.e., it represents a “cumulatively considerable contribution” to the cumulative air quality impact).

Additionally, for the SDAB, the RAQS serves as the long-term regional air quality planning document for the purpose of assessing cumulative operational emissions to ensure that the SDAB continues to make progress toward NAAQS and CAAQS attainment status. As such, cumulative projects located in the San Diego region would have the potential to result in a cumulative impact to air quality if, in combination, they would conflict with or obstruct implementation of the RAQS. Similarly, individual projects that ar e inconsistent with the regional planning documents upon which the RAQS is based would have the potential to result in cumulative operational impacts if they represent development and population increases beyond regional projections.

The SDAB has been designated as a federal nonattainment area for O 3 and a state nonattainment area for O 3, PM10, and PM 2.5. PM10 and PM2.5 emissions associated with construction generally result in “near-field” impacts.

The nonattainment status is the result of cumulative emissions from all sources of these air pollutants and their precursors within the SDAB. Construction would be short term and temporary, and once construction is completed, construction-related emissions would cease. Operational emissions generated by the reduced project would not exceed the significance thresholds for VOCs, NOx, CO, SOx, PM10, or PM2.5, and would not cause a significant impact.

As such, the reduced project would result in less -than-significant impacts to air quality relative to operational emissions.

Construction of the reduced project would result in the temporary addition of pollutants to the local airshed caused by soil disturbance, fugitive dust emissions, and combustion pollutants from on-site construction equipment, as well as from off-site trucks hauling construction materials. Construction emissions can vary substantially from day to day, depending on the level of activity, the specific type of operation, and for dust, the prevailing weather conditions. Therefore, such emissions levels can only be estimated, with a corresponding uncertainty in precise ambient air quality impacts. Fugitive dust (PM10 and PM 2.5) emissions would primarily result from grading and site preparation activities. NO x and CO emissions would primarily result from the use of construction equipment and motor vehicles.

Construction emissions were calculated using CalEEMod for the estimated worst -case day over the construction period associated with each phase and reported as the maximum daily emissions estimated during each year of construction (202 6 and 202 7). Construction schedule assumptions, including phase type, duration, and sequencing, were based on information provided by the applicant and is intended to represent a reasonable scenario based on the best information available. A detailed depiction of th e construction schedule—including information regarding phasing, equipment u sed during each phase, haul trucks, vendor trucks, and worker vehicles—is included in Section 2.1, Construction, of this report. The information contained in Appendix A (CalEEMod Output Files) was used for the CalEEMod inputs.

Implementation of the reduced project would generate temporary air pollutant emissions from entrained dust, off- road equipment, vehicle emissions, architectural coatings, and asphalt pavement application. Entrained dust results from the exposure of earth surfaces to wind from the direct disturbance and movement of soil, resulting in PM10 and PM 2.5 emissions. The reduced project is subject to SDAPCD Rule 55, Fugitive Dust Control. This rule requires that the reduced project take steps to restrict visible emissions of fugitive dust beyond the property line.

Compliance with Rule 55 would limit fugitive dust (PM 10 and PM 2.5) that may be generated during grading and construction activities. To account for dust control measures in the calculations, it was assumed that the active sites would be watered at least two times daily, resulting in an approximately 55% reduction of PM. Compliance with Rule 55 would be required as a standard condition of project approval or for issuance of a grading permit.

Exhaust from internal combustion engines used by construction equipment, hauling trucks (dump trucks), vendor trucks (delivery trucks), and worker vehicles would result in temporary emissions of NO x, VOC, CO, SOx, PM10, and PM2.5. Application of architectural coatings, such as exterior/interior paint and other finishes, would also produce VOC emissions; however, the contractor is required to procure architectural coatings from a supplier in compliance with the requirements of SDAPCD Rule 67.0.1, Architectur al Coatings. This rule requires manufacturers, distributors, and end users of architectural and industrial maintenance coatings to reduce VOC emissions from the use of these coatings, primarily by placing limits on the VOC content of various coating categories (SDAPCD 2015).

The reduced project would comply with SDAPCD Rule 67.0.1 through the incorporation of low -VOC architectural coatings. The VOC content assumed for the analysis was 50 g/L for interior coatings and 100 g/L for exterior coatings.

As shown in Table 4, daily construction emissions would not exceed the significance thresholds for NO x, CO, SOx, PM10, or PM2.5; however, the reduced project would exceed the significance threshold for VOC. The reduced project would result in fewer daily emissions compared to the original project.

Following completion of construction activities, the reduced project would generate VOC, NOx, CO, SOx, PM10, and PM2.5 emissions from mobile sources, including vehicular traffic generated by residents of the reduced project; area sources, including the use of landscaping equipment and consumer products; and from architectural coatings.

As shown in Table 5, the daily operational emissions from the reduced project would not exceed the significance thresholds for VOC, NOx, CO, SO x, PM10, or PM 2.5. Operational emissions from the reduced project would be less than those of the original project.

Regarding long-term cumulative operational emissions in relation to consistency with local air quality plans, the SIP and RAQS serve as the primary air quality planning documents for the state and SDAB, respectively. The SIP and RAQS rely on SANDAG growth projections based on population, vehicle trends, and land use plans developed by the cities and the County as part of development of their general plans. Development that is consistent with the growth anticipated by local plans would be consistent with the SIP and RAQS and would result in emissions that are accounted for. Projects that conform to the permitted land use, or result in a less emissions-intensive use, and are therefore accounted for in the SIP and RAQS and would not be considered to result in cumulatively considerable impacts from operational emissions. As stated previously, the reduced project would result in fewer vehicle miles traveled than buildout of the land use built under the existing land use designation that was anticipated by the RAQS, and would be within the housing growth projections assumed in the SIP and RAQS ; therefore, the reduced project would not result in significant regional emissions that are not accounted for within the RAQS.

However, project construction would exceed the significance threshold for VOC. As a result, the potential for the reduced project to result in a cumulatively considerable net increase of any criteria pollutant for which the reduced project region is nonattainment under an applicable national or California ambient air quality standard is potentially significant.

Threshold 3: Would the project expose sensitive receptors to substantial pollutant concentrations? Air quality varies as a direct function of the amount of pollutants emitted into the atmosphere, the size and topography of the air basin, and the prevailing meteorological conditions. Air quality problems arise when the rate of pollutant emissions exceeds the rate of dispersion. Reduced visibility, eye irritation, and adverse health impacts on those persons termed “sensitive receptors” are the most serious hazards of existing air quality conditions in the area. Some land uses are considered more sensitive to changes in air quality than others, depending on the population groups and the activities involved. People most likely to be affected by air pollution, as identified by CARB, include children, older adults, athletes, and people with cardiovascular and chronic respiratory diseases; however, for the purposes of this analysis, residents are also considered sensitive receptors. As such, sensitive receptors include residences, schools, playgrounds, childcare cen ters, athletic facilities, long -term healthcare facilities, rehabilitation centers, convalescent centers, and retirement homes.

Health Impacts of Toxic Air Contaminants
In addition to impacts from criteria pollutants, project impacts may include emissions of pollutants identified by the state and federal government as TACs or hazardous air pollutants. State law has established the framework for California’s TAC identification and control program, which is generally more stringent than the federal program and aimed at TACs that ar e a problem in California. The s tate has formally identified more than 200 substances as TACs, including the federal hazardous air pollutants, and is adopting appropriate control measures for sources of these TACs. The greatest potential for TAC emissions during construction would be diesel particulate emissions from heavy-duty equipment operations and heavy-duty trucks, and the associated health impacts to sensitive receptors.

The following measures are required by state law to reduce diesel particulate emissions:
▪ Fleet owners of mobile construction equipment are subject to the CARB Regulation for In -use Off-road Diesel Vehicles (Title 13 California Code of Regulations, Chapter 9, Section 2449), the purpose of which is to reduce DPM and criteria pollutant emissions from in-use (existing) off-road diesel-fueled vehicles. ▪ All commercial diesel vehicles are subject to Title 13, Section 2485 of the California Code of Regulations, limiting engine idling time. Idling of heavy-duty diesel construction equipment and trucks during loading and unloading shall be limited to 5 minutes; electric auxiliary power units should be used whenever possible.

The greatest potential for TAC emissions during construction would be DPM emissions from heavy-duty equipment operations and heavy-duty trucks during construction of the reduced project and the associated health impacts to sensitive receptors.

However, as a precautionary measure, an HRA was performed to evaluate the risk from diesel exhaust emissions on existing sensitive receptors and future onsite receptors from construction activities. The HRA methodology was described in Section 2.1, and the detailed assessment is provided in Appendix B. Table 6 summarizes the results of the HRA for the original project and reduced project construction.

Notes: CEQA = California Environmental Quality Act; HIC = Chronic Hazard Index.

The results of the HRA demonstrate that the TAC exposure from construction diesel exhaust emissions from the previous and reduced project would result in cancer risk on site below the 10 in 1 million threshold, as well as Chronic Hazard Index less than 1.0. The reduced project would result in a lower cancer risk than the original project. Therefore, TAC emissions from construction of the reduced project would not expose sensitive receptors to substantial pollutant concentrations and would result in a less than significant impact. Upon completion of construction, the reduced project would not generate substantial TAC emissions. As such, impacts would be less than significant during operation.

Health Impacts of Carbon Monoxide
As described previously, exposure to high concentrations of CO can result in dizziness, fatigue, chest pain, headaches, and impairment of central nervous system functions. Mobile-source impacts, including those related to CO, occur essentially on two scales of motion. Regionally, project-related construction travel would add to regional trip generation and increase the vehicle miles traveled within the local airshed and the SDAB. Locally, construction traffic would be added to the roadway system in the vici nity of the reduced project site. Although the SDAB is currently an attainment area for CO, there is a potential for the formation of microscale CO “hotspots” to occur immediately around points of congested traffic. Hotspots can form if such traffic occurs during periods of poor atmospheric ventilation, is composed of a large number of vehicles cold -started and operating at pollution - inefficient speeds, and/or is operating on roadways already crowded with non-project traffic. Because of continued improvement in vehicular emissions at a rate faster than the rate of vehicle growth and/or congestion, the potential for CO hotspots in the SDAB is steadily decreasing.

The Governor’s Office of Planning and Research and the California Natural Resources Agency have issued new CEQA Guidelines for analyzing transportation impacts. By July 1, 2020, all CEQA lead agencies must analyze a project’s transportation impacts using vehicle -miles traveled. Vehicle-miles traveled measures the distances vehicles will travel to and from a project, rather than congestion levels at intersections (LOS, graded on a scale of A–F). To account for this shift from LOS to vehicle-miles traveled, and evaluate the potential for CO hotspots for the reduced project, analysis performed by SCAQMD is leveraged as follows.

The SDAB is a CO maintenance area (western and central part of the SDAB only). As a screening analysis, t he SCAQMD conducted CO modeling for the 2003 Air Quality Management Plan (Appendix V of SCAQMD 2003) for the four worst-case intersections in the South Coast Air Basin: (1) Wilshire Boulevard and Veteran Avenue, (2) Sunset Boulevard and Highland Avenue, (3) La Cienega Boulevard and Century Boulevard, and (4) Long Beach Boulevard

and Imperial Highway. At the time the 2003 Air Quality Management Plan was prepared, the intersection of Wilshire Boulevard and Veteran Avenue was the most congested intersection in Los Angeles County, with an average daily traffic volume of about 100,000 vehicles per day. Using CO emission factors for 2002, the peak modeled CO 1- hour concentration was estimated to be 4.6 ppm at the intersection of Wilshire Boulevard and Veteran Avenue.

For potential future development associated with approval of the reduced project , the daily traffic volume of 100,000 vehicles would be conservative compared to the traffic volumes of nearby intersections. When added to the maximum 1-hour CO concentration from 2019 through 2021 at the San Diego – 11403 Rancho Carmel Drive monitoring station, which was 4.1 ppm in 2019, the 1-hour CO would be 8.7 ppm, while the CAAQS is 20 ppm.

The SCAQMD modeled future year 8-hour CO concentrations at the Central Los Angeles monitoring site of 4.6 ppm in 2020. Adding the 4.6 ppm to the maximum 8-hour CO concentration from 2019 through 2021 at the San Diego – 11403 Rancho Carmel Drive monitoring station, which was 2.5 ppm in 2019, the 8-hour CO would be 7.1 ppm, while the CAAQS is 9.0 ppm.

Accordingly, CO concentrations at congested intersections would not exceed the 1-hour or 8-hour CO CAAQS unless projected daily traffic would exceed 100,000 vehicles per day. Potential future development at the reduced project site would not increase daily traffic volumes at any study intersection to more than 100,000 vehicles per day (LLG 2022).3 Therefore, it is concluded that the reduced project traffic is not anticipated to create a CO hotspot , as emissions would be dispersed rapidly and would not be concentrated, and therefore no CO hotspots would be created. As such, impacts to sensitive receptors with regard to potential CO hotspots resulting from the reduced project’s contribution to cumulative traffic-related air quality impacts would be less than significant.

Health Impacts of Criteria Air Pollutants
Construction of the reduced project would result in emissions that exceed the threshold for VOC without mitigation; however, project construction would not exceed significance thresholds for NO x, CO, SO x, PM10, or PM2.5. Project operation would not exceed significance thresholds for VOC, NO x, CO, SO x, PM 10, or PM 2.5. VOCs and NO x are precursors to O3, for which the SDAB is designated as nonattainment with respect to the NAAQS and CAAQS (the SDAB is designated by the EPA as an attainment area for the 1 -hour O 3 NAAQS standard). The health effe cts associated with O 3 are generally associated with reduced lung function. The contribution of VOCs and NO x to regional ambient O3 concentrations is the result of complex photochemistry. The increases in O3 concentrations in the SDAB due to O3 precursor emissions tend to be found downwind from the source location to allow time for the photochemical reactions to occur. However, the potential for exacerbating excessive O 3 concentrations also depends on the time of year that the VOC emissions occur because exceedances of the O3 CAAQS/NAAQS tend to occur between April and October when solar radiation is highest. The holistic effect of a single project’s emissions of O 3 precursors is speculative due to the lack of quantitative methods to assess this impact. Operation of the reduced project would not exceed the significance threshold for NO x; therefore, implementation of the reduced project would contribute minimally to regional O 3 concentrations and the associated health effects. Although emission reductions from the following project design features were not quantified, the reduced project would install electric vehicle charging stations, install bicycle infrastructure, implement Transportation Demand Management Plan, install electric or solar water heaters that would result in co -benefits of reducing the reduced project ’s

3 For each study intersection in each scenario evaluated in the Traffic Impact Analysis, all 10 study intersections were estimated to result in less than 100,000 vehicles per day in every scenario evaluated (ranging from 4,649 vehicles to 44,977 vehicles).

operational emissions of VOC and NOx. However, due to exceedances in construction-generated emissions of VOC, the reduced project could result in potential health effects associated with VOCs.

Operation of the reduced project would not contribute to exceedances of the NAAQS or CAAQS for NO2. As discussed above, the reduced project would implement required CAP Checklist items that would result in co -benefits of reducing the reduced project’s operational emissions of VOC and NOx. Health effects that result from NO2 and NOx include respiratory irritation, which could be experienced by nearby receptors during the periods of heaviest use of off-road construction equipment. However, project construction would be relatively short term, and off -road construction equipment would be operating at various portions of the site and would not be concentrated in one portion of the site at any one time. In addition, existing NO 2 concentrations in the area are well below the NAAQS and CAAQS standards. Because project-generated NOx emissions would not exceed the significance threshold, the reduced project would not result in potential health effects associated with NO2 and NOx.

CO tends to be a localized impact associated with congested intersections. The associated potential for CO hotspots are discussed above and were determined to be a less -than-significant impact. Furthermore, the existing CO concentrations in the area are well below the NAAQS and CAAQS standards. Thus, the reduced project ’s CO emissions would not contribute to significant health effects associated with this pollutant.

Construction and operation of the reduced project would also not exceed thresholds for PM10 or PM2.5, and would not contribute to exceedances of the NAAQS or CAAQS for PM or obstruct the SDAB from coming into attainment for these pollutants. The reduced project would also not result in substantial DPM emissions during construction or operation, and therefore, would not result in significant health effects related to DPM exposure. Additionally, the reduced project would implement dust control strategies and be required to comply with SDAPCD Rule 55, Fugitive Dust, which limits the amount of fugitive dust generated during construction. Due to the minimal contribution of PM during construction and operation, the reduced project is not anticipated to result in health effects associated with PM10 or PM2.5.

In summary, because operation of the reduced project would not result in exceedances of the SDAPCD significance thresholds, the potential health effects associated with criteria air pollutants would be less than significant.

Furthermore, there are numerous scientific and technological complexities associated with correlating criteria air pollutant emissions from an individual project to specific health effects or potential additional nonattainment days, and there are currently no modeling tools that could provide reliable and meaningful additional informatio n regarding health effects from criteria air pollutants generated by individual projects within the SDAPCD ’s jurisdiction.

The California Supreme Court’s Sierra Club v. County of Fresno (2018) 6 Cal. 5th 502 decision (referred to herein as the Friant Ranch decision) (issued on December 24, 2018) addresses the need to correlate mass emission values for criteria air pollutants to specific health consequences, and contains the following direction from the California Supreme Court: “The Environmental Impact Report (EIR) must provide an adequate analysis to inform the public how its bare numbers translate to create potential adverse impacts or it must explain what the agency does know and why, given existing scientific constraints, it cannot translate potential health impacts further” (italics original). Currently, the SDAPCD, CARB, and EPA have not approved a quantitative method to reliably, meaningfully, and consistently translate the mass emission s estimates for the criteria air pollutants resulting from a project to specific health effects. In addition, there are numerous scientific and technological complexities associated with

correlating criteria air pollutant emissions from an individual project to specific health effects or potential additional nonattainment days.

In connection with the judicial proceedings culminating in issuance of the Friant Ranch decision, the South Coast Air Quality Management District (SCAQMD) and San Joaquin Valley Air Pollution Control District (SJVAPCD) filed amicus briefs attesting to the extreme difficulty of correlating an individual project’s criteria air pollutant emissions to specific health impacts. Both SJVAPCD and SCAQMD have among the most sophisticated air quality modeling and health impact evaluation capabilities of the air distr icts in California. The key, relevant points from SCAQMD and SJVAPCD briefs are summarized below.

In requiring a health impact type of analysis for criteria air pollutants, it is important to understand how O3 and PM are formed, dispersed, and regulated. The formation of O 3 and PM in the atmosphere, as secondary pollutants, 4 involves complex chemical and physical interactions of multiple pollutants from natural and anthropogenic sources.

The O 3 reaction is self -perpetuating (or catalytic) in the presence of sunlight because NO 2 is photochemically reformed from nitric oxide (NO). In this way, O3 is controlled by both NOx and VOC emissions. The complexity of these interacting cycles of pollutants means that incremental decreases in one emission may not result in proportional decreases in O3 (NRC 2005). Although these reactions and interactions are well understood, variability in emission source operations and meteorology creates uncertainty in the modeled O 3 concentrations to which downwind populations may be exposed (NRC 2005). Once formed, O3 can be transported long distances by wind, and due to atmospheric transport, contributions of precursors from the surrounding region can also be important (EPA 2008).

Because of the complexity of O3 formation, a specific tonnage of VOCs or NOX emitted in a particular area does not equate to a particular concentration of O 3 in that area (SJVAPCD 2015). PM can be divided into two categories:
directly emitted PM and secondary PM. Secondary PM, like O 3, is formed via complex chemical reactions in the atmosphere between precursor chemicals such as SO x and NO x. Because of the complexity of secondary PM formation, including the potential to be transported long distances by wind, the tonnage of PM -forming precursor emissions in an area does not necessarily result in an equivalent concentration of secondary PM in that area (SJVAPCD 2015). This is especially true for individual projects, where project -generated criteria air pollutant emissions are not derived from a single “point source ” but from construction equipment and mobile sources (passenger cars and trucks) driving to, from, and around the reduced project site.

Another important technical nuance is that health effects from air pollutants are related to the concentration of the air pollutant that an individual is exposed to, not necessarily the individual mass quantity of emissions associated with an individual project. For example, health effects from O3 are correlated with increases in the ambient level of O3 in the air a person breathes (SCAQMD 2015). However, it takes a large amount of additional precursor emissions to cause a modeled increase in ambient O3 levels over an entire region (SCAQMD 2015). The lack of link between the tonnage of precursor pollutants and the concentration of O 3 and PM2.5 formed is important because it is not necessarily the tonnage of precursor pollutants that causes human health effects; rather, it is the concentration of resulting O 3 that causes these effects (SJVAPCD 2015). Indeed, the ambient air quality standards, which are statutorily required to be set by the EPA at levels that are requisite to protect the public health, are established as concentrations of O3 and PM2.5 and not as tonnages of their precursor pollutants (EPA 2018a). Because the ambient air quality standards are focused on achieving a particular concentration region -wide, the tools and plans for attaining the ambient air quality standards are regional in nature. For CEQA analyses, project-generated emissions are typically estimated in pounds per day or tons per year and compared to mass daily or annual emission

thresholds. Although CEQA thresholds are established at levels that the air basin can accommodate without affecting the attainment date for the Ambient Air Quality Standards , even if a project exceeds established CEQA significance thresholds, this does not mean that the concentration of O 3 or PM that will be created at or near the reduced project site on a particular day or month of the year, or what specific health impacts will occur, can easily be determined (SJVAPCD 2015).

In regard to regional concentrations and air basin attainment, the SJVAPCD emphasized that attempting to identify a change in background pollutant concentrations that can be attributed to a single project, even one as large as the entire Friant Ranch Specific Plan, is a theoretical exercise. The SJVAPCD brief noted that it “would be extremely difficult to model the impact on NAAQS attainment that the emissions from the Friant Ranch project may have” (SJVAPCD 2015). The situation is further complicated by th e fact that background concentrations of regional pollutants are not uniform either temporally or geographically throughout an air basin, but are constantly fluctuating based on meteorology and other environmental factors. The SJVAPCD noted that the currently available modeling tools are equipped to model the impact of all emission sources in the San Joaquin Valley Air Basin on attainment (SJVAPCD 2015). The SJVAPCD brief then indicated that, “Running the photochemical grid model used for predicting O3 attainment with the emissions solely from the Friant Ranch project (which equate to less than one-tenth of one percent of the total NOx and VOC in the Valley) is not likely to yield valid information given the relative scale involved” (SJVAPCD 2015).

The SCAQMD and SJVAPCD have indicated that it is not feasible to quantify project -level health impacts based on existing modeling (SCAQMD 2015; SJVAPCD 2015). Even if a metric could be calculated, it would not be reliable because the models are equipped to mod el the impact of all emission sources in an air basin on attainment and would likely not yield valid information or a measurable increase in O 3 concentrations sufficient to accurately quantify O3-related health impacts from an individual project.

Nonetheless, following the Supreme Court’s Friant Ranch decision, some Environmental Impact Reports where estimated criteria air pollutant emissions exceeded applicable air district thresholds have included a quantitative analysis of potential project-generated health effects using a combination of a regional photochemical grid model (PGM)5 and the EPA’s Benefits Mapping and Analysis Program (BenMAP or BenMAP–Community Edition [CE]).6 The publicly available health impact assessments (HIAs) typically present results in terms of an increase in health incidences and/or the increase in background health incidence for various health outcomes resulting from a project’s estimated increase in concentrations of O3 and PM2.5.7 The five publicly available HIAs have concluded

5 The first step in the publicly available health impact assessment is running a regional photochemical grid model (PGM), such as the Community Multiscale Air Quality (CMAQ) model or the Comprehensive Air Quality Model with extensions (CAMx) , to estimate the increase in concentrations of O3 and PM2.5 as a result of project-generated emissions of criteria and precursor pollutants. Air districts, such as the SCAQMD, use photochemical air quality models for regional air quality planning. These photochemical models are large-scale air quality models that simulate the changes of pollutant concentrations in the atmosphere using a set of mathematical equations characterizing the chemical and physical processes in the atmosphere (EPA 2017). 6 After estimating the increase in concentrations of O3 and PM2.5, the second step in the five examples is use of BenMAP or BenMAP- CE to estimate the resulting associated health effects. BenMAP estimates the number of health incidences resulting from changes in air pollution concentrations (EPA 2018b). The health impact function in BenMAP -CE incorporates four key sources of data:

that the evaluated project’s health effects associated with the estimated project -generated increase in concentrations of O3 and PM2.5 represent a small increase in incidences and a very small percent of the number of background incidences, indicating that these health impacts are negligible and potentially within the model ’s margin of error. In addition, the results of the five HIAs conclude d that project emissions would not result in a substantial increase in health incidences, and the estimated emissions and assumed toxicity were also conservatively inputted into the HIA and, thus, overestimated health incidences, particularly for PM2.5.

As explained in the SJVAPCD brief (SJVAPCD 2015) and noted previously, running the PGM used for predicting O3 attainment with the emissions solely from an individual project, like the Friant Ranch project or the reduced project, is not likely to yield valid information given the relative scale involved. The five examples reviewed support the SJVAPCD’s brief contention that consistent, reliable, and meaningful results may not be provided by methods applied at this time. Accordingly, additional work in the industry, and more importantly, air district participation, is needed to develop a more meaningful analysis to correlate project-level mass criteria air pollutant emissions and health effects for decision makers and the public. Furthermore, at the time of writing, no HIA has concluded that health effects estimated using the PGM and BenMAP approach are substantial, provided that the estimated project- generated incidences represent a very small percent of the number of background incidences, potentially within the model’s margin of error.

In summary, because construction of the reduced project could result in exceedances of the significance thresholds for VOC, the potential health effects associated with criteria air pollutants, specifically O 3, would be potentially significant. Notably, there are numerous scientific and technological complexities associated with correlating criteria air pollutant emissions from an individual project to specific health effects or potential additional nonattainment days, and there are currently no modeling tools that could provide reliable and meaningful additional information regarding health effects from criteria air pollutants generated by individual projects.

Valley Fever Exposure
Valley Fever is not highly endemic to San Diego County, and within San Diego County, the incidence rate in the reduced project area is below the County and statewide average. Construction of the reduced project would comply with SDAPCD Rule 55, which limits the amount of fugitive dust generated during construction. Strategies the reduced project would implement to comply with SDAPCD Rule 55 and control dust include watering two times per day and limiting speed on unpaved roads to 15 miles per hour.

Based on the low incidence rate of Coccidioidomycosis in San Diego County and the reduced project ’s implementation of dust control strategies, it is not anticipated that earth -moving activities during project construction would result in exposure of nearby sensitive receptors to Valley Fever. Therefore, the reduced project would have a less than significant impact with respect to Valley Fever exposure for sensitive receptors.

Threshold 4: Would the project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Odors would be generated from vehicle and equipment exhaust emissions during construction of the reduced project. Odors produced during construction would be attributable to concentrations of unburned hydrocarbons from tailpipes of construction equipment and from architectural coatings. Such odors would disperse rapidly from

MEMORANDUM

SPECIFIC PLAN PROJECT ALTERNATIVE

13170 23 FEBRUARY 2024

the reduced project site and generally occur at magnitudes that would not affect substantial numbers of people.

Therefore, impacts associated with odors during construction of the reduced project would be less than significant.

Land uses and industrial operations associated with odor complaints include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding (CARB 2005). The reduced project would not engage in any of these activities. Moreover, typical odors generated from operation of the reduced project would primarily include vehicle exhaust generated by residents and through the periodic use of landscaping and maintenance equipment. Therefore, the reduced project would result in an odor impact that is less than significant.

3.3 Mitigation Measures
Mitigation Measure (MM-)AQ-1 would be implemented to reduce VOC emissions generated during construction of the reduced project.

MM-AQ-1 Architectural Coatings. The reduced project shall u se low volatile organic compound (VOC) architectural coatings for interior application that do not exceed VOC content of 10 grams per liter, for exterior application that do not exceed VOC content of 50 grams per liter , and for parking application do not exceed VOC content of 100 grams per liter.

For Threshold 2 ( Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard), Table 7 shows the estimated maximum daily construction emissions associated with construction of the original project and reduced project with implementation of MM-AQ-1.

less than 2.5 microns.

See Appendix A for output files and modeling details.

The values shown are the maximum summer or winter daily emissions results from CalEEMod and provided in Appendix A. The maximum emissions assumes compliance with SDAPCD Rule 55, Fugitive Dust Control and implementation of MM -AQ-1, use of low- VOC architectural coatings.

As shown in Table 7, daily construction emissions of the original project or reduced project would not exceed the significance thresholds for VOC, NOx, CO, SOx, PM10, or PM2.5. The reduced project would result in fewer emissions during construction compared to the original project. Therefore, the potential for the reduced project to result in a cumulatively considerable net increase of any criteria pollutant for which the reduced project region is nonattainment under an applicable national or California ambient air quality standard, and health effects of criteria air pollutants would be reduced to a less than significant impact with mitigation. 4 Greenhouse Gas Emissions Assessment

4.1 Thresholds of Significance
California has developed guidelines to address the significance of GHG emissions impacts that are contained in Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.). Appendix G provides that a project would have a significant environmental impact if it would:

1. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment

2. Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases.

The Appendix G thresholds for GHGs do not prescribe specific methodologies for performing an assessment, do not establish specific thresholds of significance, and do not mandate specific mitigation measures. Rather, the CEQA Guidelines emphasize the lead agency’s discretion to determine the appropriate methodologies and thresholds of significance consistent with the manner in which other impact areas are handled in CEQA (CNRA 2009). Additional guidance regarding assessment of GHGs is discussed below.

City of San Marcos CAP Checklist
The City adopted the Final CAP on December 8, 2020. The CAP relies on a screening threshold based on land use size and a CAP Consistency Checklist to determine whether a project’s emissions would be consistent with GHG emissions estimated within the City’s CAP. The CAP Consistency Checklist is used to determine significance in accordance with CEQA Guidelines Section 15183.5; therefore, the CAP Consistency Checklist was used to evaluate the reduced project’s significance with respect to GHG emissions.

4.2 Impact Analysis
This section evaluates the GHG emissions impacts associated with the reduced project. The significance criteria described in Section 4.1, Thresholds of Significance, were used to evaluate impacts associated with the construction and operation of the reduced project.

SPECIFIC PLAN PROJECT ALTERNATIVE

13170 25 FEBRUARY 2024

Threshold 1: Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
Threshold 2: Would the project conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
City of San Marcos’ Climate Action Plan Consistency
This section evaluates the reduced project’s impacts to GHG in accordance with the City’s 2020 CAP Consistency Checklist. A completed CAP Checklist is included as Appendix C. The first step in this section evaluates a project’s GHG emissions consistent with the City’s Guidance to Demonstrating Consistency with the City of San Marcos Climate Action Plan: For Discretionary Projects Subject to CEQA (City’s Guidance Document) (Ci ty of San Marcos 2020c). New discretionary development projects subject to CEQA review that emit less than 500 MT CO 2e annually would not contribute considerably to cumulative climate change impacts, as stated in the City’s Guidance Document, and therefore, would be considered consistent with the CAP and associated emissions projections.

For projects that are subject to CAP consistency review, the next step in determining consistency is to assess the reduced project’s consistency with the growth projections used in development of the CAP. This section allows the City to determine a project’s consistency with the land use assumptions used in the CAP.

Step 1
Question 1
Step 1 of the CAP Checklist determines land use consistency. Question 1 of Step 1 asks if a project is less than a certain size. It is deemed consistent with the City’s CAP by emitting fewer than 500 MT CO2e per year and would be less than significant. The reduced project is larger than the screening size (55 multi-family residential units) and therefore would answer Yes to this question and must proceed to Question 2 of Step 1.

Question 2
Question 2 of Step 1 asks if the reduced project is consistent with the existing General Plan land use designation.

The reduced project proposes residential use, but the General Plan currently designates the site as Industrial (I).

Therefore, the reduced project would answer No to this question and would proceed to Question 3 of Step 1.

Question 3
Question 3 of Step 1 asks if the reduced project would generate GHG emissions equal to or less than estimated GHG emissions generated under the land use built under the existing land use designation . The following section discusses the results of the construction and emissions analysis based on the methodologies described in Section

3.3.2.1, Construction, and Section 3.3.2.2, Operation, (in the Air Quality and Greenhouse Gas Emissions Technical Report for the Pacific Project , dated February 6, 2023 (Dudek 2023)) for the existing land use designation and original project.

13170 26 FEBRUARY 2024

Existing Land Use Designation
As shown in Table 14 of the Dudek report (Dudek 2023), estimated annual GHG emissions from the existing land use designation would be approximately 5,619 MT CO 2e per year. With amortized construction emissions, the annual operational emissions would be 5,655 MT CO2e per year.

Reduced project
Construction Emissions
Construction of potential future development at the reduced project site would result in GHG emissions that are primarily associated with use of off -road construction equipment, on -road vendor trucks, and worker vehicles.

CalEEMod was used to calculate the annual GHG emissions based on the construction scenario described in Section 2.1, Construction, and Appendix A. Construction of potential residential development at the reduced project site is anticipated to commence in June 2026, lasting approximately 18 months. On-site sources of GHG emissions include off-road equipment and off-site sources include on -road vehicles (haul trucks, vendor trucks, and worker vehicles). Table 8 presents construction emissions for the reduced project from on -site and off -site emission sources.

Notes: CO2 = carbon dioxide; CH4 = methane; N2O = nitrous oxide; CO2e = carbon dioxide equivalent.

See Appendix A for complete results.

As shown in Table 8, the estimated total GHG emissions during construction of potential development at the reduced project site would be approximately 975 MT CO 2e. Construction GHG emissions of the potential development at the reduced project site amortized over 30 years would be 33 MT CO 2e per year. Amortized construction emissions are added to operational emissions to be compared to development allowed under the existing land use designation.

Operational Emissions
Operation of potential future residential development at the reduced project site would generate GHG emissions through area sources; motor vehicle trips to and from the reduced project site; energy use (natural gas and generation of electricity consumed by the reduced project ); solid waste disposal; and generation of electricity associated with water supply, treatment, and distribution and wastewater treatment. CalEEMod was used to calculate the annual GHG emissions based on the operational assumptions described in Section 2.2 , Operation.

The estimated operational emissions of potential residential development at the reduced project site are presented in Table 9.

See Appendix A for complete results.

As shown in Table 9, estimated annual GHG emissions from potential residential development at the reduced project site would be approximately 2,396 MT CO2e per year. With amortized construction emissions, the annual operational emissions would be 2,428 MT CO2e per year. Estimated annual GHG emissions from development of the site under the existing land use designation would be 5,655 MT CO 2e per year. Therefore, potential future development associated with the approval of the reduced project would generate l ess GHG emissions when compared to the existing land use designation. The reduced project also resulted in fewer GHG emissions compared to the original project (3,866 MT CO2e per year) (Dudek 2023). The reduced project would answer Yes to Question 3 of Step 1 and can proceed to Step 2 of the Checklist.

Step 2
The second step of CAP consistency review is to evaluate a project’s consistency with the applicable strategies and measures of the CAP. Each checklist item is associated with a specific GHG reduction measure in the City’s CAP.

Not applicable (“N/A”) should only be checked based on the direction provided in each checklist item question. All projects for which the measure is applicable must demonstrate that the reduced project would implement measures consistent with the checklist item, or fully substantiate how the item would be infeasible for project implementation. “N/A” responses are subject to Planning Division review and approval. If “No” is provided as a response to a question, the reduced project would be determined to be inconsistent with the CAP and would result in a significant GHG impact.

Checklist Item 1. Electric Vehicle Charging Stations (Measure T -2) This checklist item applies to multi-family residential and non-residential projects. It asks if the reduced project will install electric vehicle charging stations (Level 2 or better) in at least 5% of the total parking spaces provided on site.

The reduced project would comply with this checklist item. The reduced project consists of development of 299 residential units, and a GPA/Rezone to convert the existing Industrial (I) land use and zoning designations to a Specific Plan Area designation to allow for residential development . The reduced project would include 646 total

Checklist Item 2. Bicycle Infrastructure (Measure T -8) This checklist item applies to residential and non -residential projects. It asks if the following conditions are met, would the reduced project pay its fair-share contribution to bicycle infrastructure improvements of the following:
▪ Intersection or roadway segment improvements are proposed as part of the reduced project. ▪ The City ’s General Plan Mobility Element identifies bicycle infrastructure improvements at any intersection(s) or roadway segment(s) that would be improved as part of the reduced project.

The reduced project would comply with this checklist item. The reduced project will include the following roadway and bicycle improvements:

Active Transportation Improvements

1. Construct sidewalks to close sidewalk gaps on the site frontage on La Mirada Drive, Pacific Street, and Linda Vista Drive.

2. Construct or preserve space for the portions of proposed bicycle facilities on Linda Vista Drive from Pacific Street to Las Posas Road immediately adjacent to the site.

3. Provide transit stop amenities including, at a minimum, bench, shelter, and trash can at the southbound stop at the intersection of Las Posas Road / Linda Vista Drive located on the southwest corner of the intersection.

Accordingly, the reduced project would answer “Yes” to this question.

Checklist Item 3. Transportation Demand Management (Measure T -9) This checklist item applies to residential and non-residential projects. Will the reduced project develop and implement a Transportation Demand Management (TDM) Plan that includes, at a minimum, all of the TDM strategies listed below? ▪ Provide discounted monthly transit pass or provide at least 25 percent transit fare subsidy to residents/employees.
▪ Provide designated car-share, carpool, vanpool, and/or park-and-ride parking spaces. ▪ Provide pedestrian connections between all internal uses and to all existing or planned external streets around the reduced project site(s).
▪ Provide secure bicycle parking spaces or bicycle racks, showers, and clothes lockers. ▪ Encourage telecommuting for employees (allow one telecommute day per week or compressed work weeks) or provide a telecommute work center with common office space and equipment available to residents.

-or
▪ Would the reduced project implement and monitor for four (4) years a TDM program that demonstrates an alternative transportation (i.e. carpool, public transit, bicycle, walk, telecommute) mode share of at least 29 percent for all residents?
The reduced project would comply with this checklist item. The reduced project would develop and implement a TDM plan that incorporates the required TDM strategies listed in this measure. The reduced project would answer Yes to this checklist question.

Checklist Item 4. Reduce Parking Near Transit (Measure T -12) This checklist item applies to multi-family residential projects. If located within one-half mile of a major transit stop, would the reduced project provide at least 27% fewer parking spaces than required for the same use based on the City’s municipal code parking requirements?
The reduced project is not located within ½ mile of a major transit stop defined as a bus or light -rail station with fixed service and 10-minute minimum headways during peak hours. Therefore, the reduced project would answer “N/A” to this question.

Checklist Item 5. Water Heaters (Measure E -1)
This checklist item applies to residential projects and asks if the reduced project would install one of, or a combination of, the following water heater types in place of natural gas water heaters:
▪ Electric heat pump water heater
▪ Instantaneous electric water heater
▪ Electric tank
▪ Solar water heater with heat pump water heater backup ▪ Solar water heater with electric tank backup
The reduced project would comply with this checklist item. The reduced project would install non-natural gas water heaters that would meet the requirements of this checklist item. The reduced project would answer Yes to this checklist question.

Checklist Item 6. Photovoltaic Installation (Measure E -2) This checklist item applies to non-residential projects. Therefore, the reduced project would answer “N/A” to this checklist item.

Checklist Item 7. Landscaping Water Use (Measure W -1)

SPECIFIC PLAN PROJECT ALTERNATIVE

13170 30 FEBRUARY 2024

The reduced project would comply with this checklist item. The reduced project's landscaping would meet the requirements within the City's Water Efficient Landscape Ordinance. As prescribed in Section 4.3.1 of the specific plan, The selected plants are well suited to the local soils and have proven to flourish within the reduced project area’s climate and are consistent with AB 1881 requirements and the City of San Marcos Water Efficient Landscape Ordinance (WELO) and Municipal Code, Title 20. The reduced project will include composting, climate adapted plants, mulch, minimal use of turf, and smart water-efficient irrigation systems to minimize water use. Accordingly, the reduced project would answer “Yes” to this question.

Checklist Item 8. Urban Tree Canopy (Measure C -2)
This checklist item applies to residential and non-residential projects and asks if the reduced project is providing more than 10 parking spaces, will the reduced project plant at least one tree per five parking spaces provided? The reduced project would comply with this checklist item. The reduced project is providing 646 parking spaces and will plant at least 130 trees to satisfy this checklist requirement. Accordingly, the reduced project would answer “Yes” to this question.

Summary
The reduced project requires a General Plan Amendment because it is proposing a residential development on a site zoned as Industrial (I). Therefore, a GHG analysis was performed to analyze the emissions of the existing zoned site and the reduced project. The reduced project was shown to result in fewer GHG emissions than the existing land use designation, and would implement all applicable checklist items within the City’s 2020 CAP. Therefore, the reduced project would be consistent with the City’s 2020 CA P, and impacts to GHG emissions would be less than significant consistent with the original project.

Consistency with Statewide Greenhouse Gas Reduction Strategies The reduced project’s consistency with statewide GHG reduction strategies is summarized in detail in Table 1 0 through consideration of the reduced project ’s various construction and operational components and their relationship to specified laws and regulations designed to reduce GHG emissions from such components.

Control Measure
Waste associated with the reduced project will be
disposed per state requirements for landfills, material recovery facilities, and transfer stations. Per the
statewide GHG emissions inventory, the largest
emissions from waste management sectors come from
landfills, and are in the form of CH4.

In 2010, CARB adopted a regulation that reduces
emissions from CH4 in landfills, primarily by requiring owners and operators of certain uncontrolled municipal
solid waste landfills to install gas collection and control systems, and requires existing and newly installed gas
and control systems to operate in an optimal manner.

The regulation allows local air districts to voluntarily enter into a memorandum of understanding with CARB
to implement and enforce the regulation and to assess
fees to cover costs of implementation.

Mandatory
Commercial
Recycling (AB

effective reduction of GHG emissions from new
passenger vehicles.

Pursuant to AB 1493, CARB adopted regulations that
establish a declining fleet average standard for CO2,
CH4, N2O, and HFCs (air conditioner refrigerants) in new passenger vehicles and light-duty trucks beginning with the 2009 model year and phased-in through the 2016

The program combines the control of smog, soot, and
global warming gases and requirements for greater
numbers of zero-emission vehicles into a single
package of standards called Advanced Clean Cars. By
2025, new automobiles will emit 34% fewer global
warming gases and 75% fewer smog-forming

(as codified in SB 32) , and the long-term, carbon neutrality 2045 goal (as set forth in EO B -55-18) by being infill development with access to multi -modal transportation options and incorporating design features such as installation of smart meters, installation of programmable thermostats, implementation of a parking management plan, walkability and bicycle access throughout the reduced project site, walking access to the nearby Sprinter station, and drought-tolerant landscaping.8
Consistency with SANDAG’s RTP/SCS
At the regional level, SANDAG’s RTP/SCS has been adopted for the purpose of reducing GHG emissions attributable to passenger vehicles in the San Diego region. In October 2015, SANDAG adopted its RTP/SCS, which meets CARB’s 2020 and 2035 reduction targets for the region. The RTP/SCS does not regulate land use or supersede the exercise of land use authority by SANDAG’s member jurisdictions, but it is a relevant regional reference document for purposes of evaluating the intersection of land use and transportation patterns and the corresponding GHG emissions. CARB has recognized that the approved RTP/SCS is consistent with SB 375 (CARB 2015).

For purposes of the RTP/SCS consistency evaluation, the reduced project would increase access to transit because it is located approximately 0.6 miles from the Palomar College Sprinter station and a bus station is located in front of the reduced project site.9 The reduced project would provide connectivity by extending the sidewalk to neighboring communities, the shopping center across South Las Posas Road, the bus station, and the Sprinter station. The reduced project ’s proximity to State Route 78 further allows for easy regional connectivity to employment centers, shopping areas, and recreation opportunities. Furthermore, the reduced project would implement applicable measures in the City’s 2020 CAP Consistency Checklist (see Appendix C), installing electric vehicle charging stations, installing bicycle infrastructure, implementing a Transportation Demand Management plan, and reducing parking near transit. These measures would further reduce the reduced project’s GHG emissions from vehicle trips, increase access to transit, and encourage alternative modes of transportation. The reduced project’s density, land use type, and location are consistent with SANDAG’s RTP/SCS, which provides for increased access to transit and promotes regional connectivity to employment centers, shopping areas, and recreation opportunities. The features mentioned above would help facilitate alternative transit usage and reduce the overall vehicle trips, thereby reducing the reduced project’s regional GHG emissions.

Based on the considerations outlined above, the reduced project would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs, and potential impacts would be less than significant. No mitigation measures are required.

8 GHG emission reductions from the listed design features were not quantified. 9 The City uses the North County Transit District (NCTD) for Coaster rail service, Sprinter light rail service, and Breeze bus service for connections throughout the County of San Diego. Sprinter service operates between Escondido and Oceanside with connections to Interstate 5 and the Coaster rail service operating out of the City of Oceanside. The NCTD operates the Palomar College Sprinter, which is within a short walk from the reduced project area. In addition, a bus stop is located in front of the reduced project site. Connections to Orange County can be made via the Metrolink in the City of Oceanside. Similarly, connections to Riverside Transit Authority buses can be made via the transit station in Oceanside and Escondido. Both the Metrolink connection in Oceanside and the Riverside Transit Authority Bus connection in Oceanside and Escondido are accessible through Sprinter light rail service. These public transit options will offer residents of the reduced project area quick access to a variety of alternative modes of transportation.

4.3 Mitigation Measures
The reduced project would not result in significant impacts; therefore, no mitigation is required. 5 Conclusions
Criteria air pollutant emissions generated during construction and operation of the reduced project would not exceed SDAPCD’s significance thresholds or result in a cumulatively considerable net increase in emissions. The reduced project would result in fewer emissions of criteria air pollutants during operation and construction compared to the original project. Similarly, the reduced project would not create a CO hotspot or expose sensitive receptors to substantial concentrations of TACs. Therefore, the reduced project would result in a less than significant impact.

Estimated total GHG emissions generated during operation, including amortized construction emissions, would be below the existing land use designation for the site . The reduced project would be consistent with the City’s CAP.

Furthermore, the reduced project would result in fewer GHGs compared to the original project. The reduced project would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs because there are currently no mandatory GHG regulations or finalized agency guidelines that would apply to implementation of this project. Accordingly, potential cumulative GHG impacts would be less than significant.

As such, the reduced project would not result in significant impacts to air quality or GHG emissions. 6 References
