Re: EPC 24-01 Riverside La Sierra & Victoria Residential Project – Air Quality and GHG Technical Memorandum
______________________________________________________________________________
1.0 Purpose
The purpose of this memorandum is to document the results of the air quality (AQ) and greenhouse gas (GHG) emissions assessment as it relates to the potential environmental impacts associated with the construction and operation of the proposed Residential Project on approximately 9.91 acres gross acres.
Project Location & Description
1.1 Project Location:
The proposed project site is located in the City of Riverside, Riverside County, Californi a on the southeast corner of the intersection of La Sierra Avenue and Victoria Avenue and is referred to as APN: 136-220-016.
1.2 Description:
The Applicant is proposing a project that includes 49 single-family residential units, 3,687 square foot water quality basin, interior roadway, driveways, utilities, and landscaping on an approximately 9.91-acre parcel.
2.0 Air Quality & Greenhouse Gas (GHG) Assessment
2.1 Determination of Significance:
The criteria used to determine the significance related to potential Project related air quality and greenhouse gas emission impacts is based on the Californi a Environmental Quality Act (CEQA) Environmental Checklist, Appendix G Thresholds:
2.1.1 Air Quality / GHG Impacts:
Would the Project: Conflict with or obstruct implementation of the applicable air quality plan? Would the Project: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? Would the Project: Expose sensitive receptors to substantial pollutant concentrations? Would the Project: Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Would the Project: Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
Would the Project: Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? 2.1.2 Air Quality Thresholds: South Coast Air Quality Management District (SCAQMD) was created by the state legislature to facilitate compliance with the federal Clean Air Act and to implement the state air quality program. Toward that end, SCAQMD develops regulations designed to achieve these public health standards by reducing emissions from business and industry. The Project site is located within the South Coast Air Basin (SCAB) which is under the jurisdiction of the SCAQMD. Table 2.1-1 describes the regional significance thresholds established by the SCAQMD to meet national and state air quality standards. Table 2.1-1: South Coast Air Quality Management District Regional Significance Thresholds Pollutant Emissions (Construction) (pounds/day) Emissions (Operational) (pounds/day) NOx 100 55 VOC 75 55 PM10 150 150 PM2.5 55 55 SOx 150 150 CO 550 550 Source: South Coast Air Quality Management District CEQA Air Quality Significance Thresholds, March 2015. 2.1.3 GHG Thresholds: The City of Riverside adopted a Climate Action Plan (CAP) as part of the Restorative Growthprint Economic Prosperity Action Plan and Climate Action Plan in 2016, referred to as the Riverside Restorative Growthprint or RRG. The RRG represents 3 separate but integrated planning efforts including: Western Riverside Council of Governments (WRCOG) subregional Climate Action Plan (Subregional CAP), RRG – Economic Prosperity Action Plan (RRG-EPAP), and RRG – Climate Action Plan (RRG-CAP). The City has adopted 2020 and 2035 emissions reduction targets with a 2020 target of a 15% reduction and 2035 target of 49% reduction form the 2010 baseline. To achieve the proposed targets the City developed local reduction measures. The local reduction measures in the RRG-CAP are organized into four major sectors: • Energy (including electricity and natural gas consumption) • Transportation and Land Use • Water • Solid Waste The City however has not adopted aa qualitative significance threshold for determining a project’s GHG emissions impacts. Therefore, the SCAQMD’s Interim CEQA GHG Significance Threshold for Stationary Sources, Rules and Plans proposed a screening level of 3,000 Metric Tons CO2 equivalent per year (MTCO2e/yr) for residential and commercial projects which has been accepted and used within the City of Riverside, the County of Riverside, and many cities within the South Coast Air Basin. 3.0 Environmental Impacts: This section analyzes the proposed Project’s potential Air Quality and GHG impacts for construction, operations, plan consistency, and cumulative effects. 3.1 Construction Emissions: Construction emissions for the Project were estimated by using the California Emissions Estimator Model (CalEEMod) version 2022.1.1.22, which is a statewide land use emissions computer model designed to provide a uniform platform for government agencies to quantify potential criteria pollutant emissions associated with both construction and operations emissions. CalEEMod is authorized for use to assess project emissions by the SCAQMD. Construction emissions are summarized in Table 3.1-1. Construction emissions were based on CalEEMod Land Use for development of a 49 Single-Family dwelling unit Project. Construction was estimated for a 300-day construction schedule, with default values used for the schedule. Default values were used for each construction phase including site preparation, grading, building construction, paving, and architectural coating as well as defaults for off-road construction equipment. Peak emissions represent the highest value from the summer and winter modeling. SCAQMD significance thresholds were used for determining the project’s impacts. All construction emissions are below the SCAQMD thresholds. Table 3.1-1 - Summary of Peak Construction Emissions (No Mitigation) Year/Season Emissions (lbs/day) ROG NOX CO SOX PM10 PM2.5 Construction 2024 (Summer) 3.74 36.0 34.4 0.10 9.49 5.47 Construction 2024 (Winter) 1.29 11.5 14.3 0.02 0.78 0.53 Construction 2025 (Summer) 30.0 10.7 14.5 0.02 0.71 0.47 Construction 2025 (Winter) 1.20 10.7 14.1 0.02 0.71 0.47 Maximum Daily Emissions 30.0 36.0 34.4 0.10 9.49 5.47 SCAQMD Regional Threshold 75 100 550 150 150 55 Threshold Exceeded? NO NO NO NO NO NO Source: CalEEMod 2022.1.1.22 Datasheets. (Appendix A).
3.2 Operational Emissions: Operational emissions for the Project were estimated by using the California Emissions Estimator Model (CalEEMod) which is a statewide land use emissions computer model designed to provide a uniform platform for government agencies to quantify potential criteria pollutant emissions associated with both construction and operations emissions. CalEEMod is authorized for use to assess project emissions by the SCAQMD. Operations emissions include stationary (residence emissions), mobile (transportation emissions), and area (on-going architectural coatings, consumer product use, landscaping maintenance emissions), default values were used . SCAQMD significance thresholds were used for determining the project’s impacts Operation emissions are summarized in Table 2.3-1 for Summer Emissions and Table 2.3-2 for Winter Emissions. All operations emissions are below the SCAQMD thresholds. 3.2.1 AREA SOURCE EMISSIONS Architectural Coatings Over a period of time the buildings that are part of this Project will be subject to emissions resulting from the evaporation of solvents contained in paints, varnishes, primers, and other surface coatings as part of Project maintenance. The emissions associated with architectural coatings were calculated using CalEEMod. Consumer Products Consumer products include, but are not limited to detergents, cleaning compounds, polishes, personal care products, and lawn and garden products. Many of these products contain organic compounds which when released in the atmosphere can react to form ozone and other photochemically reactive pollutants. The emissions associated with use of consumer products were calculated based on assumptions provided in CalEEMod. In the case of the commercial uses proposed by the Project, no substantive on-site use of consumer products is anticipated. Landscape Maintenance Equipment Landscape maintenance equipment would generate emissions from fuel combustion and evaporation of unburned fuel. Equipment in this category would include lawnmowers, shedders/grinders, blowers, trimmers, chain saws, and hedge trimmers used to maintain the landscaping of the Project. The emissions associated with landscape maintenance equipment were calculated based on assumptions provided in CalEEMod. 3.2.2 ENERGY SOURCE EMISSIONS Combustion Emissions Associated with Natural Gas and Electricity Electricity and natural gas are used by almost every project. Criteria pollutant emissions are emitted through the generation of electricity and consumption of natural gas. However, because electrical generating facilities for the Project area are located either outside the region (state) or offset through the use of pollution credits (RECLAIM) for generation within the air basin, criteria pollutant emissions from offsite generation of electricity is generally excluded from the evaluation of significance and only natural gas use is considered. The emissions associated with natural gas use were calculated using CalEEMod.
3.2.3 MOBILE SOURCE EMISSIONS Vehicles Project-related operational air quality impacts derive primarily from vehicle trips generated by the Project. CalEEMod Version 2022.1.1.22 default values were used for the projects trip characteristics for operational truck and passenger vehicle totals. Fugitive Dust Related to Vehicular Travel Vehicles traveling on paved roads would be a source of fugitive emissions due to the generation of road dust inclusive of tire wear particulates. The emissions estimates for travel on paved roads were calculated using CalEEMod.

3.3 Greenhouse Gas Emissions (GHG): GHG emissions for the Project were estimated by using the California Emissions Estimator Model (CalEEMod) which is a statewide land use emissions computer model designed to provide a uniform platform for government agencies to quantify potential criteria pollutant emissions associated with both construction and operations emissions. CalEEMod is authorized for use to assess project emissions by the SCAQMD. As previously discussed, the SCAQMD significance threshold of 3,000 MTCO2e/Year was used for determining the project’s GHG emissions impacts. Construction and operation emissions are presented in Table 3.3-1 and summarized in Table 3.3-2. The GHG emissions for both construction and operations of the Project are estimated to below the 3,000 MTCO2e/Year threshold. Table 3.3-1 - Project Greenhouse Gas Emissions Source GHG Emissions MT/yr N2O CO2 CH4 CO2e Mobile Sources 0.03 549 0.03 559 Area < 0.005 0.84 < 0.005 0.85 Energy < 0.005 186 0.02 186 Water/Wastewater < 0.005 15.4 0.07 17.6 Solid Waste 0.000 4.00 0.40 14.0 Refrigerant 0.11 30-year Amortized Construction GHG 15.23 TOTAL Metric Tons / Year 792.79 SCAQMD Threshold 1 3,000 Exceed Threshold?

(Appendix A). 3.4 Objectionable Odors: According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. The Project does not propose any of the above-described uses. Potential odor sources associated with the Project may result from construction equipment exhaust and the application of asphalt and architectural coatings during construction activities and the temporary storage of typical solid waste (refuse) associated with the proposed Project’s long-term operational uses. 1 CalEEMod GHG Emissions for GHG CO2e is calculated in Metric Tons (MT) per year.
The construction odor emissions would be temporary, short-term, and intermittent in nature and would cease upon completion of the respective phase of construction and is thus considered less than significant. It is expected that Project-generated refuse would be stored in covered containers and removed at regular intervals in compliance with the City’s solid waste regulations. Additionally, the Project is required to comply with the provisions of SCAQMD Rule 402 “Nuisance” which was established to reduce odorous emissions into the atmosphere. Therefore, odors associated with the proposed Project construction and operations would be less than significant and no mitigation is required. 3.5 Sensitive Receptors: Some people, such as individuals with respiratory illnesses or impaired lung function because of other illnesses, persons over 65 years of age, and children under 14, are particularly sensitive to certain pollutants. Facilities and structures where these sensitive people live or spend considerable amounts of time are known as sensitive receptors. For the purposes of a CEQA analysis, the SCAQMD considers a sensitive receptor to be a receptor such as the following are land uses (sensitive sites) where sensitive receptors are typically located: • Schools, playgrounds, and childcare centers • Long-term health care facilities • Rehabilitation centers • Convalescent centers • Hospitals • Retirement homes • Residences Sensitive receptor locations are generally identified as facilities where it is possible that an individual could remain for 24 hours. Commercial and industrial facilities are not included in the definition of sensitive receptor because employees typically are present for shorter periods of time, such as eight hours. The closest sensitive receptors to the Project site are include residential uses around the Project site, as indicated in Table 3.5-1 Table 3.5-1 – Sensitive Receptor Locations Closest Receptor Distance from Project Site Boundary (feet) Distance from Project Construction Center (feet) Residence Southeast 75 425 Residence Northeast across Millsweet Pl 60 370 Residence – North across Victoria Ave. 175 500 Residential Southwest across La Sierra Ave. 115 450 Source: Google Earth Pro, March 25, 2024 The properties around the Project site are existing residential uses and as such the Project would be compatible with surrounding land uses and would not adversely impact sensitive receptors during operations. Whenever a project would require use of chemical compounds that have been identified in SCAQMD Rule 1401; placed on CARB’s air toxics list pursuant to Assembly Bill 1807 (AB 1807), Air Contaminant Identification and Control Act (1983); or placed on the EPA’s National Emissions Standards for Hazardous Air Pollutants, a health risk assessment (HRA) is required by the SCAQMD. Residential, commercial, and office uses do not use substantial quantities of TACs. Guidance for conducting a Health risk Assessments (HRA), typically includes the following project types proposed for sites within the specified distance to an existing or planned (zoned) sensitive receptor land use must be evaluated: • Any industrial project within 1,000 feet; • A distribution center (40 or more trucks per day) within 1,000 feet; • A major transportation project (50,000 or more vehicles per day) within 1,000 feet; • A dry cleaner using perchloroethylene within 500 feet; and, • A gasoline dispensing facility within 300 feet. The Project is a residential development and does not produce toxic air emissions such as those generated by industrial manufacturing uses or uses that generate heavy-duty diesel truck emissions. 3.6 Localized Air Quality Impacts The South Coast Air Quality Management District has established Localized Significance Thresholds (LST) which are used to determine whether a project may generate significant adverse localized air quality impacts for both construction and on-site operations. For the purposes of a CEQA analysis, the SCAQMD considers a sensitive receptor to be to be a receptor such as residential, hospital, convalescent facility where it is possible that an individual could remain for 24 hours If the calculated emissions for the proposed construction or operational activities are below the LST emission thresholds then the proposed construction or operation activity is not significant for air quality. (SCAQMD) The nearest sensitive receptors are residential homes located approximately 60 feet from the Project site boundary, 370 feet from the center of the site to the north of the project site. The Project site is located in Source Receptor Area (SRA) #23 – Metropolitan Riverside County. The total daily disturbed acreage used for the Project is approximately 5-acres (this is the maximum acreage to be graded/disturbed per day) with the closest receptor at 25 meters ( 82 feet). Table 3.6-1 identifies the maximum daily localized emissions thresholds that are applicable to the Project.
Table 3.6-1: Maximum Daily Localized Emissions Thresholds Pollutant Construction Operations Localized Thresholds (pounds per day) NOX 270 270 CO 1,577 1,577 PM10 13 4 PM2.5 8 2 Source: Localized Thresholds presented in this table are based on the SCAQMD Final Localized Significance Threshold Methodology, July 2008. Localized Construction Emissions As shown in Table 3.6-2, using the CalEEMod Mitigated Construction Emissions which incorporates Rule 403 dust control measures, the localized construction emissions would not exceed the applicable SCAQMD LSTs for emissions for construction activities with Rule 403 measures applied to the Project, including watering site 2 times per day, reducing speed on site, and street sweeping. Thus, a less than significant impact would occur for Project-related construction-source localized emissions and no mitigation is required. Table 3.6-2: Summary of Localized Significance Construction Emissions Grading Emissions Emissions (lbs/day) NOX CO PM10 PM2.5 Maximum Daily Emissions 36.0 34.4 9.49 5.47 SCAQMD Localized Threshold 270 1,577 13 8 Threshold Exceeded? NO NO NO NO Source: Air Quality Assessment, (Appendix A). Localized On-Site Operational Emissions According to the SCAQMD LST methodology, LSTs would apply to the operational phase of a project, if the project includes substantive stationary sources of emissions, or uses that attract mobile sources that may spend long periods queuing and idling at the site (e.g., industrial uses, transfer facilities, and warehouses). The Project does not propose or require uses that would constitute substantive stationary sources of emissions; or uses that attract mobile emissions sources that may spend long periods queuing and idling at the site. Accordingly, no operational-source emissions LST analysis is required. 3.7 CO “Hotspot” Analysis: As discussed below, the Project would not result in potentially adverse CO concentrations or “hotspots.” Further, detailed modeling of Project-specific carbon monoxide (CO) “hot spots” is not needed to reach this conclusion. The SSAB is designated attainment under the CAAQS and NAAQS for CO. An adverse CO hotspot would occur if an exceedance of the state one-hour standard of 20 ppm or the eight-hour standard of 9 ppm were to occur. It has long been recognized that CO hotspots are caused by vehicular emissions, primarily when idling at congested intersections. Due to changing regulations vehicle emissions standards have become increasingly stringent in the last twenty 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 Basin have steadily declined. The SCAQMD, as part of their 2003 AQMP, conducted modeling for CO Hotspot Analysis at multiple congested intersections in their South Coast Air Basin, including the intersection of Wilshire Boulevard and Veteran Avenue, considered one of the most congested intersections in Southern California with an ADT of approximately 100,000 vehicles. The CO concentrations modeled by the SCAQMD’s analysis identified all traffic induced CO levels below Federal and State thresholds. As the CO hotspots were not modeled at an intersection that accommodates over 100,000 vehicles per day, it can be reasonably deduced that CO hotspots would not be experienced at any intersections in the vicinity of the proposed project. Given the extremely low level of CO concentrations in the project area and no project-traffic related impacts at any intersections, project-related vehicle emissions are not expected to result in the CO concentrations exceeding the State or federal CO standards. 3.8 Cumulative Impacts: The project area is designated as a non-attainment area for ozone and a non-attainment area for PM2.5 and PM10. The Project would comply with the mandatory requirements of SCAQMD’s Rule 403 (fugitive dust control) during construction, as well as all other adopted AQMP emissions control measures. The project also is required to comply with California Code of Regulations Title 13, Division 3, and specifically its Chapter 1, Article 4.5, Section 2025, “Regulation to Reduce Emissions of Diesel Particulate Matter, Oxides of Nitrogen and Other Criteria Pollutants, from In- Use Heavy-Duty Diesel-Fueled Vehicles” and its Chapter 10, Article 1, Section 2485, “Airborne Toxic Control Measure to Limit Diesel-Fueled Commercial Motor Vehicle Idling.” Per SCAQMD rules and mandates, and California Code of Regulation requirements, as well as the CEQA requirement that significant impacts be mitigated to the extent feasible, these same requirements are imposed on all projects in the South Coast Air Basin. In determining whether the project would result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions, which exceed quantitative thresholds for ozone precursors), the non-attainment pollutants of concern for this impact are ozone and PM10. In developing the thresholds of significance for air pollutants disclosed above the SCAQMD considered the emission levels for which a project’s individual emissions would be cumulatively considerable. If a project exceeds the identified significance thresholds, its emissions would be cumulatively considerable, resulting in significant adverse air quality impacts to the region’s existing air quality conditions.
As shown in Tables 3.1-1, 3.2-1, 3.2-2, 3.3-1, 3.3-2, and 3.6-2 above, the project does not exceed the identified significance thresholds, as such, emissions would not be cumulatively considerable. 3.9 Conformity and Consistency: The following analysis is consistent with the preferred analysis approach recommended by the SCAQMD CEQA Air Quality Handbook. 3.9.1 Conformity with Air Quality Management Plans: The Project is located within the SCAB and under the jurisdiction of the SCAQMD. Under the Federal Clean Air Act, the SCAQMD has adopted a variety of attainment plans (i.e., “Air Quality Management Plans”) for a variety of non-attainment pollutants. A complete list of the various air quality management plans is available from the SCAQMD on their website at: http://www.aqmd.gov/home/air-quality/clean-air-plans/air-quality-mgt-plan The SCAQMD is responsible for maintaining and ensuring compliance with the various Air Quality Management Plans. Conformity is determined based on the following criteria: • A project is non-conforming if it conflicts with or delays implementation of any applicable attainment or maintenance plan. A project may also be non-conforming if it increases the gross number of dwelling units, increases the number of trips, and/or increases the overall vehicle miles traveled in an affected area (relative to the applicable land use plan). • A project is conforming if it complies with all applicable SCAQMD rules and regulations, complies with all proposed control measures that are not yet adopted from the applicable plan(s), and is consistent with the growth forecasts in the applicable plan(s) (or is directly included in the applicable plan). 3.9.2 Consistency with Emission Thresholds: As shown in Tables 3.1-1, 3.2-1, 3.2-2, 3.3-1, 3.3-2, and 3.6-2 the Project would not exceed SCAQMD significance thresholds for any criteria pollutant during construction or during long-term operation. Accordingly, the Project’s air quality emissions are less than significant. 3.9.3 Consistency with Control Measures: The construction contractors are required to comply with rules, regulations, and control measures including but not limited to controlling Fugitive Dust (Rule 403), Supplemental Fugitive Dust Control Requirements for Coachella Valley Sources (Rule 403.1), and the application of architectural coatings during building construction (Rule 1113). 3.9.4 Consistency with Growth Forecasts: The Project site’s land use is designated as Low Density Residential (LDR), with a zoning of Single-Family Residential (R-1-1/2) with a maximum dwelling unit per acre of 2 du/ac. The R-1-1/2 zone would provide for development on the 8.81-acre site a maximum of 18 dwelling units. The Project will require a General Plan Amendment (GPA) and Change of Zone (CZ) which increases the number of units and estimated population growth as compared to the current land use land use designation and zoning. Therefore, the Project must be evaluated to determine if the Project’s impacts would exceed the assumptions in the 2022 AQMP.
The projections in the AQMP for growth assumptions are based on the Southern California Association of Governments (SCAG) Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). The RTP/SCS is updated every four years with the current adopted plan being the 2020-2045 RTP/SCS. According to the 2020-2045 RTP/SCS the forecast for the City’s population growth is estimated to at 19,000 residents and additional households at 5,500. The proposed Project would include the development of 49 single family dwelling units. According to the State of California Department of Finance E-5 Population and Housing Estimates for Cities, Counties, and the State, 2020-2023 the City has an estimated 3.05 persons per household.2 The project would therefore increase the current population by approximately 150 residents. The increase of 150 residents is well within the estimated 5,500 projected increase in residents and as such the Project would be consistent with the growth assumptions from the 2020-2045 RTP/SCS used in the SCAQMD plans. 4.0 Conclusion Based on the assessment in Section 3.0 all estimated Project emissions for construction and operations are below the SCAQMD significance threshold levels and as such impacts to the environment for Air Quality and Greenhouse Gases are less than significant. Additionally, the proposed Project will not conflict with any air quality or GHG plans. 2 California Department of Finance E-5 Spreadsheet, accessed: https://dof.ca.gov/forecasting/Demographics/estimates/e-5-population-and-housing-estimates-for-cities-counties-and-the-state-2020-2023/ KPC EHS Consultants, LLC
