Technical Memorandum:
Air Quality and Greenhouse Gas Assessment of
1980 Yountville Cross Road, Yountville, California
September 29, 2023
Introduction
The purpose of this memorandum is to evaluate the potential air quality and greenhouse gas (GHG) emissions of the proposed Oak + Vine subdivision in the Town of Yountville (Project). The Town of Yountville has requested this analysis to determine if the Project qualifies for a categorical exemption under the California Environmental Quality Act (CEQA). Section 15332(d) of the CEQA Guidelines provides a categorical exemption for certain in-fill development projects. To qualify for this exemption, the Project must meet specific criteria, including that approval of the project would not result in any significant air quality effects. This memorandum estimates the air quality and GHG emissions of the Project and compares these emissions to the Bay Area Air Quality Management District (BAAQMD) thresholds.
Project Description
Project
The project site is a 1.32-acre residential parcel developed with a historic single-family home. The project site is bordered by the Crossroads multi-family development on the west and the north, and a singlefamily development to the east. South of Yountville Cross Road is primarily single-family residential. The applicant proposes to subdivide the parcel into nine parcels, construct eight additional single-family market-rate units with eight junior accessory dwelling units, relocate the historic single-family dwelling and construct a duplex with two one-bedroom low-income affordable units on the former site of the historic dwelling.
Design Elements and Best Management Practices
For this analysis, the following design elements and best management practices (BMPs) are assumed to be incorporated into the Project to reduce the potential for adverse air quality impacts and to comply with BAAQMD recommendations. These recommendations are contained within the BAAQMD’s CEQA Air Quality Guidelines which the Air District Board of Directors adopted on April 20, 2022 (BAAQMD, 2022).
These are standard BMPs that could be included as conditions of approval, should the Town choose to approve the project.
BAAQMD Climate Impact Design Elements (BAAQMD, 2022; Table 3-2):
▪ The project will achieve compliance with off-street electric vehicle requirements in the most recently adopted version of CALGreen Tier 21.
BAAQMD Basic Best Management Practices for Construction-Related Fugitive Dust Emissions (BAAQMD, 2022; Table 5-2):
▪ All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day.
▪ All haul trucks transporting soil, sand, or other loose material off-site shall be covered. ▪ All visible mud or dirt trackout onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. ▪ All vehicle speeds on unpaved roads shall be limited to 15 mph. ▪ All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.
Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. ▪ All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph.
▪ All trucks and equipment, including their tires, shall be washed off prior to leaving the site. ▪ Unpaved roads providing access to sites located 100 feet or further from a paved road shall be treated with a 6- to 12-inch layer of compacted layer of wood chips, mulch, or gravel. ▪ Publicly visible signs shall be posted with the telephone number and name of the person to contact at the lead agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s General Air Pollution Complaints number shall also be visible to ensure compliance with applicable regulations.
BAAQMD Best Practices for Construction-Related Exhaust Emissions (BAAQMD, 2016; Table 1):
▪ The applicant/general contractor for the project shall demonstrate to the local jurisdiction that all off-road equipment greater than 25 hp that will be operating for more than 20 hours over the entire duration of the construction activities at the site, including equipment from subcontractors meets the following requirement:
▪ 1) Be Zero Emissions OR 2) have engines that meet or exceed either US EPA or ARB Tier 2 off-road emission standards; and 3) have engines that are retrofitted with an ARB Level 3 Verified Diesel Emissions Control Strategy (VDECS), if one is available for the equipment being used (equipment with engines meeting Tier 4 Interim or Tier 4 Final emission standards automatically meet this requirement, therefore a VDECS would not be required).
▪ Idling time of diesel powered construction equipment, trucks and generators shall be limited to no more than 2 minutes. Clear signage shall be provided for construction workers at all access points.
▪ All construction equipment shall be maintained and properly tuned in accordance with the manufacturers’ specifications.
▪ Portable diesel generators shall be prohibited. Grid power electricity should be used to provide power at construction sites; or propane and natural gas generators may be used when grid power electricity is not feasible.
1 Tier 2 expands on 2022 CALGreen mandatory provisions by requiring a dedicated 208/240V branch circuit for each dwelling unit. The mandatory provisions require the installation of raceways/conduits and to have available service panel capacity to support electrical vehicle (EV) charging. Tier 2 requires the wiring to be installed as well.
Environmental and Regulatory Setting
Environmental Setting
Yountville is located within the San Francisco Bay Area Air Basin (SFBAAB), which is comprised of nine counties including all of Napa, Alameda, Contra Costa, Santa Clara, San Francisco, San Mateo, Marin and the southern portions of Sonoma and Solano. The SFBAAB is unclassified or in attainment for all state and federal ambient air quality standards except for the state and federal ozone standards, state PM10 2 standards, and state and federal PM2.5
3 standards.
Local air quality is influenced by the mountains bordering Napa Valley, proximity to more urban areas, seasonal wind patterns, and meteorological conditions. While air quality is generally good, ozone and PM2.5 levels can exceed health standards. Elevated ozone levels are a rare occurrence primarily caused by summer winds carrying reactive organic gases (ROG) and oxides of nitrogen (NOx) from the south and these precursor compounds of ozone are trapped in the valley. Elevated PM2.5 levels are more common and occur primarily in the winter when fireplaces are in use and easterly winds carry fine particulate matter from the Central Valley.
The closest air quality monitoring station is located in the City of Napa approximately 10 miles from the project site. The station was relocated in recent years and monitoring was suspended for logistical reasons in May 2021. The most recent available data from this station show one exceedance of state or federal ozone standards in 2020, but no exceedances in 2021. Available data from this station show 14.7 estimated exceedances of the national PM2.5 standard and 11.5 estimated exceedances of the state PM2.5 standard in 2020. There is insufficient data available to determine potential exceedances for 2021 (CARB, 2023).
BAAQMD CEQA Guidelines
The BAAQMD CEQA Air Quality Guidelines were developed to assist lead agencies in evaluating air quality and climate impacts from proposed land use projects and plans in the San Francisco Bay Area Air Basin.
The Guidelines contain instructions and examples for how a lead agency can evaluate, measure, and mitigate air quality and climate impacts generated from land use construction and operational activities.
They focus on generated emissions of criteria air pollutants and precursors, odors, toxic air contaminants, and greenhouse gases from local plans and projects. The Guidelines provide two methods for lead agencies to assess a project’s potential impacts: screening criteria and thresholds of significance.
Screening Criteria
The Screening Criteria for criteria air pollutants and their precursors are not thresholds of significance, rather they are conservative guidelines that a lead agency can use to qualitatively assess whether a project could result in potentially significant impacts. If all screening criteria are met, then the lead agency does not need to perform a detailed assessment and can presume that potential impacts due to criteria air pollutants are less than significant.
2 PM10 is particulate Matter 10 microns or less in diameter. 3 PM2.5 is particulate matter 2.5 microns or less in diameter.
If a project is consistent with all of the following screening criteria related to construction activities, then detailed air quality modeling is not required:
▪ The project size is at or below the applicable screening level size shown in Table 4-1. For residential projects, the construction screening criteria size is 254,000 square feet of single-family residential and 416,000 square feet of condo-townhouse residential. ▪ All best management practices (see Table 5-2 in Chapter 5, “Project-Level Air Quality Impacts”) are included in the project design and implemented during construction. ▪ Construction-related activities would not overlap with operational activities. ▪ Construction-related activities would not include:
o demolition,
o simultaneous occurrence of two or more construction phases (e.g., paving and building construction would occur simultaneously),
o extensive site preparation (e.g., grading, cut and fill, or earth movement), o extensive material transport (e.g., soil import and export requiring a considerable amount of haul truck activity), or stationary sources (e.g., backup generators) subject to Air District rules and regulations.
If a project is consistent with all of the following screening criteria related to operational activities, then detailed air quality modeling is not required:
▪ The project size is at or below the applicable operational screening level size shown in Table 4-1.
For residential projects, the operational screening criteria size is 421,000 square feet of singlefamily residential and 637,000 square feet of condo-townhouse residential. ▪ Operational activities would not include stationary engines (e.g., backup generators) and industrial sources subject to Air District rules and regulations. ▪ Operational activities would not overlap with construction-related activities.
Significance Thresholds
If a project does not meet the screening criteria discussed above, the BAAQMD provides project-level air quality thresholds of significance that include numerical thresholds for construction and operation emissions of ROG, NOx, PM10, PM2.5, and local carbon monoxide (CO). Construction thresholds of significance use average daily emissions while operation thresholds of significance utilize both daily and annual emissions. In addition to ROG, NOx, PM10, PM2.5, and local CO, there are odor and local risks and hazards thresholds of significance. For project-level climate impacts from greenhouse gas emissions, the thresholds of significance require satisfying certain building and operation criteria versus comparing the project’s emissions to set threshold numbers. These building and operation criteria include meeting building design measures in addition to electric vehicle codes, assessing vehicles miles traveled, and meeting greenhouse gas emission reduction strategy measures. Should a project exceed the thresholds of significance, the Guidelines provide recommendations for reducing potential air quality and climate impacts from land use development projects.
Toxic Air Contaminants
The BAAQMD CEQA Guidelines provide guidance in addressing project-related toxic air contaminants (TACs) such as diesel particulate matter (DPM), lead, and benzene, and the associated risks to the local community. Commons sources of TACs include freeways, ports, railyards, industrial facilities, gas stations and backup diesel generators.
BAAQMD has identified the following significance thresholds for local risks and hazards:
▪ Cancer Risk: > 100 in a million (from all local sources) ▪ Non-cancer: > 10.0 Hazard Index (chronic, from all local sources) ▪ PM2.5: > 0.8 μg/m3 annual average (from all local sources) These are the cumulative thresholds which apply to siting new sources and receptors. BAAQMD’s Mobile Source Screening Map provides estimates of existing health risks within the SFBAAB (BAAQMD, 2023).
The Mobile Source Screening Map shows the project site within an area that has the following background health risks associated with roadway emissions, the principal source of TACs in Yountville. ▪ Cancer Risk: 4.155 – 20.771 in a million
▪ Non-cancer: 0.015 – 0.058 hazard index
▪ PM2.5: 0.102 – 0.418 μg/m3 annual average
Climate/Greenhouse Gas Emissions
The BAAQMD CEQA Guidelines recommends evaluating the climate impacts of land use projects based on the extent to which a project’s design elements would provide a “fair share” reduction in GHG emissions, and provides two possible approaches to assess this. Under Approach A, projects that incorporate certain minimum design elements are considered to have less-than-significant climate impacts. There are four minimum design elements outlined in Approach A of the BAAQMD CEQA Guidelines, which are summarized below.
▪ The project will not include natural gas appliances or natural gas plumbing. ▪ The project will not result in any wasteful, inefficient, or unnecessary energy use as determined by the analysis required under CEQA Section 21100(b)(3) and Section 15126.2(b) of the State CEQA Guidelines.
▪ The project will achieve a reduction in project-generated vehicle miles traveled (VMT) 15% below the existing VMT per capita.
▪ The project will achieve compliance with off-street electric vehicle requirements in the most recently adopted version of CALGreen Tier 2.
Alternatively, under Approach B the BAAQMD states that a project will have a less-than-significant impact relating to GHG emissions if it is consistent with a local GHG reduction strategy that meets CEQA Guidelines Section 15183.5(b) requirements. For a local GHG reduction strategy to meet CEQA Guidelines Section 15183.5(b), it must: 1) quantify GHG emissions; 2) establish a level below which the contribution to GHG emissions would not be cumulatively considerable; 3) analyze GHG emissions from types of actions within the area; 4) specify measures and performance standards to achieve the specified emissions level; 5) establish a mechanism to monitor the plan’s progress; and 6) be adopted in a public process following environmental review. The BAAQMD CEQA Air Quality Guidelines states that if a project is claiming a less than significant climate impact by demonstrating consistency with a GHG reduction strategy, it must incorporate all elements of the GHG reduction strategy that are applicable to the project. The Town of Yountville developed a Climate Action Plan in 2016 (Town of Yountville, 2016) and then subsequently consolidated the Climate Action Plan into its General Plan Update. The General Plan / Climate Action Plan underwent environmental review and the General Plan Environmental Impact Report (EIR) included the detailed assessment required by CEQA Guidelines Section 15183.5(b).
Impact Assessment
Methods
Screening Criteria
First, the Project was assessed against the BAAQMD’s screening criteria to determine whether or not the Project required detailed air quality modeling. The Project’s construction phase very nearly meets all of the BAAQMD screening criteria; it is below the size limitation and includes all of the required BMPs, but demolition of two outbuildings is included as part of Project construction. Therefore, the construction emissions of the Project require detailed analysis. Project operation does meet all of the following screening criteria: the project is less than 421,000 square feet (single-family residential) and 637,000 square feet (condo-townhouse), it does not include any stationary engines, and the operational activities would not overlap with construction activities. Therefore, the Project meets the operational screening criteria and no further assessment of operational criteria air pollutant emissions is necessary.
Detailed Air Quality Modeling
Emissions from construction of the Project were calculated using the California Emissions Estimator Model, Version 2022.1.1.19 (CalEEMod). Emissions were estimated assuming that construction would begin in begin in October 2023 and continue through 2024. CalEEMod default assumptions were used except where project-specific information was available.
Construction Criteria Pollutant Emissions
CalEEMod emissions results are summarized below and included in Appendix A. Construction emissions are summarized in Table 1.

Source: Appendix A
As shown in Table 1, Project construction emissions of criteria pollutants are all below BAAQMD significance thresholds. In addition to the thresholds identified in the tables, BAAQMD addresses construction-related fugitive dust emissions by recommending the incorporation of Best Management Practices to reduce dust emissions. These BMPs are identified under Design Elements and BMPs above.
Therefore, construction emissions are less than significant because they are less than the thresholds of significance.
Operational Criteria Pollutant Emissions
Operational emissions are less than significant because the Project is below the BAAQMD’s screening criteria for detailed analysis. Pursuant to the BAAQMD CEQA Air Quality Guidelines (BAAQMD, 2022), the screening criteria “provide lead agencies with a conservative indication of whether implementing a proposed project could result in potentially significant criteria air pollutants and precursors impacts. If all
screening criteria for criteria air pollutants and precursors are met by a proposed project, then the lead agency would not need to perform a detailed assessment of the project’s criteria air pollutant and precursor emissions.” The Project meets all operational screening criteria and therefore no further assessment is required.
Toxic Air Contaminants
The Project is a small-scale residential development and does not propose any elements that would be a significant source of TACs. Based on the BAAQMD’s Mobile Source Screening Map, the project site is within an area that has background health risks from roadway emissions that are well below the BAAQMD’s cumulative thresholds. The 2018 General Plan Draft Environmental Impact Report identified 355 PM peak hour trips on Yountville Cross Road under existing conditions (Town of Yountville, 2018).
The existing total daily trip volumes on Yountville Cross Road are much higher; the most recent traffic count data published by Napa County indicates average daily traffic of up to 1,517 trips on Yountville Cross Road at the Town limit near the Project Site (Napa County, 2017). Operation of the Project would introduce approximately 100 trips per day which represents only a 6.6% increase in average daily traffic on Yountville Cross Road (W-Trans, 2023). The Project would introduce a relatively small number of trips on local roadways and would have a negligible impact on roadway emissions.
Construction emissions of DPM would be reduced with compliance with BAAQMD’s Best Practices for Construction-Related Exhaust Emissions identified under Design Elements and BMPs above. These measures include requiring off-road diesel equipment to meet Tier 2 emission standards and be equipped with Level 3 emission controls (e.g., diesel particulate filters). More than 90% of DPM is less than 1 micron in diameter, and thus is a subset of PM2.5. The results of the CalEEMod modeling indicate that compliance with these measures would result in a 77% reduction in exhaust PM2.5 during construction (Appendix A).
Due to compliance with BAAQMD’s Best Practices for Construction-Related Exhaust Emissions and the limited extent and duration of diesel equipment use on the project site, potential health risk impacts would be negligible, and a detailed health risk assessment is not warranted.
Climate/Greenhouse Gas Emissions
The Project is consistent with the BAAQMD CEQA Air Quality Guidelines Approach B for climate change impacts, in that it is consistent with a local GHG reduction strategy that meets the criteria under State CEQA Guidelines Section 15183.5(b). Refer to Appendix B for a complete list of the climate reduction policies and an assessment of the project’s consistency with said policies. Because the Project meets the Town of Yountville’s Climate Action Plan policies, the Project is considered to have a less-than-significant impact associated with GHG emissions and climate change.
CEQA Significance Criteria Review
To conclude this analysis, the Project is reviewed under the CEQA checklist form provided as Appendix G of the CEQA Guidelines.
Air Quality
Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project:
a) Conflict with or obstruct implementation of the applicable air quality plan? As described above, with the incorporation of the identified design elements and BMPs, the Project would not exceed BAAQMD significance thresholds for criteria air pollutants, TACS or GHG emissions.
Accordingly, the Project would not conflict with or obstruct implementation of applicable air quality plans.
b) 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? The SFBAAB is nonattainment for the state and federal ozone standards, state PM10 standards, and state and federal PM2.5 standards. As shown in Table 1, Project emissions of criteria pollutants are all below BAAQMD significance thresholds. In addition to the thresholds identified in the table, BAAQMD addresses construction-related fugitive dust emissions by recommending the incorporation of BMPs to reduce dust emissions. These BMPs are identified under Design Elements and BMPs above. The Project would not result in a cumulatively considerable increase of any criteria pollutant. c) Expose sensitive receptors to substantial pollutant concentrations? With the incorporation of the identified design elements and BMPs the Project would not expose sensitive receptors to substantial pollutant concentrations. As shown in Table 1, Project emissions of criteria pollutants are all below BAAQMD significance thresholds. Operation of the Project would generate a relatively small number of trips on local roadways and would have a negligible impact on roadway TAC emissions.
Construction emissions of DPM would be reduced with compliance with BAAQMD’s Best Practices for Construction-Related Exhaust Emissions, which include requiring off-road diesel equipment to meet Tier 2 emission standards and be equipped with Level 3 emission controls (e.g., diesel particulate filters). These measures would result in a 77% reduction in exhaust PM2.5 during construction.
BAAQMD BMPs to reduce dust emissions will also be implemented. The incorporated design elements and BMPs will ensure that the Project will not generate substantial pollutant concentrations. d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
The Project is a residential infill development within a residential area. No land uses are proposed that would have the potential to result in other emissions, including odors, that would adversely affect the surrounding community.
Greenhouse Gas Emissions
Would the project:
a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
As described above and in Appendix B, the Project would not generate greenhouse gas emissions, either directly or indirectly, that would have a significant impact on the environment. The Project includes numerous design elements and BMPs to minimize the emissions of greenhouse gases, including the use of renewable solar energy via installation of solar panels on homes, retention of
shade trees to maximize energy efficiency, and the installation of electric vehicle charging stations to minimize the use of gasoline. The Project is consistent with all of the applicable Town of Yountville’s Climate Action Plan policies and has a less-than-significant impact on greenhouse gas emissions per the BAAQMD CEQA Guidelines (2022).
b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
The Project is consistent with every applicable Climate Action Plan policy adopted by the Town of Yountville, as articulated in Appendix B. Therefore, the Project is consistent with the applicable Climate Action Plan and this impact is less than significant.
