AIR QUALITY AND GREENHOUSE GAS IMPACTS ANALYSES
In order to evaluate the questions in the Air Quality and Greenhouse Gas Emissions Sections of the checklist, quantitative significance criteria established by the local air quality agency, such as SJVAPCD, and/or the lead agency may be relied upon to make significance determinations based on mass emissions of criteria pollutants and GHGs, as determined in this report. As shown below, approval of the project would not result in any significant effects relating to air quality or greenhouse gases.
Project Emissions Estimation
The operation analysis was performed using CalEEMod version 2022.1.1.28, the official statewide land use computer model designed to provide a uniform platform for estimating potential criteria pollutant and GHG emissions associated with both construction and operations of land use projects under CEQA. The model quantifies direct emissions from construction and operations (including vehicle use), as well as indirect emissions, such as GHG emissions from energy use, solid waste disposal, vegetation planting and/or removal, and water use. The mobile source emission factors used in the model –published by the California Air Resources Board (CARB) – include the Pavley standards and Low Carbon Fuel standards. The model also identifies project design features, regulatory measures, and measures to control criteria pollutant and GHG emissions along with calculating the benefits achieved from the selected measures. CalEEMod was developed by the California Air Pollution Control Officers Association (CAPCOA) in collaboration with the SJVAPCD, the Bay Area Air Quality Management District (BAAQMD), the South Coast Air Quality Management District ( SCAQMD), and other California air districts. Default land use data (e.g., emission factors, trip lengths, meteorology, source inventory, etc.) were provided by the various California air districts to account for local requirements and conditions. As the official assessment methodology for land use projects in California, CalEEMod is relied upon herein for construction and operational emissions quantification, which forms the basis for the impact analysis.
Based on information received from the Applicant, land use data for CalEEMod input is presented in Table 1. The SJVAPCD quantitative significance thresholds shown in Table 2 were used to evaluate Project emissions impacts (SJVAPCD 2015a,b,c).

Criteria Pollutants from Project Construction
A project’s construction phase produces many types of emissions. Fugitive dust emissions, which include respirable particulate matter with an aerodynamic diameter of less than 10 microns (PM 10)
and fine particulate matter with an aerodynamic diameter of less than 2.5 microns (PM2.5), can result from a variety of construction activities, including excavation, grading, demolition, vehicle travel on paved and unpaved surfaces, and vehicle exhaust. Construction- related emissions can cause Air Quality and GHG Study for a Residential and Storage Development in Merced, CA October 3, 2024
substantial increases in localized concentrations of PM10, as well as affecting PM10 compliance with ambient air quality standards on a regional basis. Particulate emissions from construction activities can lead to adverse health effects as well as nuisance concerns such as impaired visibility and soiling of exposed surfaces. The use of diesel -powered construction equipment emits ozone precursors oxides of nitrogen (NOx) and reactive organic gases (ROG), and diesel particulate matter (DPM). Use of architectural coatings and other materials associated with finishing buildings may also emit ROG.
CEQA significance thresholds address the impacts of construction activity emissions on local and regional air quality.
The SJVAPCD’s approach to CEQA analyses of fugitive dust impacts is to require implementation of effective and comprehensive dust control measures under Regulation VIII – Fugitive PM 10 Prohibitions – rather than to require detailed quantification of emissions. PM 10 emitted during construction can vary greatly depending on the level of activity, the specific operations taking place, the equipment being operated, local soils, weather conditions, and other factors, making quantification difficult. Despite this variability in emissions, experience has shown that there are several feasible control measures that can be reasonably implemented to significantly control fugitive dust emissions from construction. The SJVAPCD has determined that implementing Best Management Practices (BMPs), primarily through frequent water application, constitutes sufficient controls to control PM
10 impacts to a level considered less than significant.
Criteria Pollutants from Project Operation
The term “project operations” refers to the full range of activities that can or may generate criteria pollutant and GHG emissions when the project is functioning in its intended use. For projects, such as office parks, shopping centers, apartment buildings, residential subdivisions, and other indirect sources, motor vehicles traveling to and from the project represent the primary source of air pollutant emissions. For industrial projects and some commercial projects, equipment operation and manufacturing processes, i.e., permitted stationary sources, can be of greatest concern from an emissions standpoint. CEQA significance thresholds address the impacts of operational emission sources on local and regional air quality.
Results of Criteria Emissions Analyses
Tables 3 and 4 show the annual and daily construction emissions while Tables 5 and 6 show the annual and daily operational emissions. These tables evaluate project emissions against SJVAPCD significance thresholds. As shown in these tables, mass emissions of criteria pollutants from construction and operation of the proposed P roject are below applicable SJVAPCD significance thresholds. Since the proposed Project would result in emissions, which are below the significance thresholds adopted for both construction and operations phase emissions, less than significant air quality impacts would occur.

Greenhouse Gas Emissions from Construction and Operation Greenhouse gases – primarily carbon dioxide ( CO2), methane ( CH4), nitrous ( N2O) oxide, and fluorinated compounds, including sulfur hexafluoride (SF 6), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs), collectively reported as carbon dioxide equivalents (CO 2e) – are directly emitted from stationary source combustion of natural gas in equipment such as water heaters, boilers, process heaters, and furnaces. GHGs are also emitted from mobile sources such as on-road and off- road vehicles burning fuels such as gasoline, diesel, biodiesel, propane, or natural gas (compressed or liquefied). Indirect GHG emissions result from electric power generated elsewhere ( i.e., power plants) used to operate process equipment, lighting, and utilities at a facility. Also, included in GHG quantification is electric power used to pump the water supply (e.g., aqueducts, wells, pipelines) and disposal and decomposition of municipal waste in landfills. (CARB 2022a,b).
California’s Building Energy Efficiency Standards are updated on an approximately three-year cycle.
The 2022 standards improved upon the 2019 standards for new construction of, and additions and alterations to, residential, commercial, and industrial buildings. The 2022 standards went into effect on January 1, 2023 [California Energy Commission (CEC) 2022].
Since the Title 24 standards require energy conservation features in new construction (e.g., high- efficiency lighting, high -efficiency heating, ventilating, and air -conditioning (HVAC) systems, thermal insulation, double-glazed windows, water conserving plumbing fixtures, etc.), they indirectly regulate and control GHG emissions.
Using CalEEMod, direct on- site and off- site GHG emissions were estimated for construction and operation, and indirect off-site GHG emissions were estimated to account for electric power used by the proposed Project , water conveyance, and solid waste disposal. CalEEMod also quantifies common refrigerant GHGs (abbreviated as “R” in the model output) used in air conditioning and refrigeration equipment, some of which are HFCs.
Results of Greenhouse Gas Emissions Analysis
SJVAPCD is responsible for protecting public health and welfare through the administration of federal and state air quality laws and policies. In December 2009, SJVAPCD adopted the Final Staff Report Addressing Greenhouse Gas Emissions Impacts under the Ca lifornia Environmental Quality Act (SJVAPCD 2009). SJVAPCD also developed guidance for land -use agencies to address GHG emission impacts for new development projects. Projects complying with an approved GHG emission reduction plan or GHG mitigation program would have a less than significant individual and Air Quality and GHG Study for a Residential and Storage Development in Merced, CA October 3, 2024
cumulative impact related to GHG emissions. Projects implementing best performance standards and reducing project -specific GHG emissions by at least 29 % compared to the business- as-usual condition would have a less than significant individual and cumulative impact on global climate change under this guidance. However, models used to estimate GHG emissions now include some of the statewide measures that previously would have been used to evaluate this 29% reduction performance standard, so this particular method of comparison is out of date. To establish the context in which to consider the project’s GHG emissions, this analysis used guidance from the adjacent Sacramento Metropolitan Air Quality Management District (SMAQMD) to determine significance.
In 2014, SMAQMD adopted a significance threshold for GHG emissions consistent with the goals of Assembly Bill (AB) 32: 1,100 metric tons (MT) CO
2e per year for construction- related and
operational emissions (SMAQMD 2020) 1. This significance threshold was developed to assess the consistency of a project’s emissions with the statewide framework for reducing GHG emissions.
Table 7 shows the Project’s GHG emissions and evaluates them against the SMAQMD significance threshold. Operational efficiency measures incorporate typical code -required energy and water conservation features. Off-site traffic impacts are included in these emissions estimates, along with construction emissions amortized over 30 years. As shown in Table 7, the proposed Project would not exceed emissions thresholds adopted by SMAQMD.

Notes:
1Comprises annual operational emissions plus construction emissions amortized over 30 years In 2012, the City of Merced adopted the Merced Climate Action Plan (CAP) to address the reduction of major sources of GHG emissions. The CAP established an emissions target of 1990 levels by 2020, commensurate with the State of California’s target (City of Merced 2012). To meet this goal, the City adopted values, goals, and strategies to control emissions. Goals of the plan include eight focus areas:
Enhanced mobility of all transportation modes;
Sustainable community design;
Water conservation and technology;
Protection of air resources;
Waste reduction;
Increased use of renewable energy sources;
1 Guidance updated in 2020.
Air Quality and GHG Study for a Residential and Storage Development in Merced, CA October 3, 2024
Building energy conservation; and
Public outreach and involvement.
The proposed Project would be built in accordance with California's Building Energy Efficiency and Title 24 standards and would therefore be consistent with the goals of the Merced CAP.
As such, the project would not conflict with any applicable plans, policies, or regulations adopted for the purpose of reducing GHG emissions. This impact would be less than significant.
IMPACT: Less Than Significant
CONCLUSION
The air quality and GHG impacts of the proposed Project were evaluated and shown to have a less than significant impact and no mitigation measures are needed.

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 28.1 annual days of extreme heat Extreme Precipitation 1.85 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 17.4 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
