Health Risk Assessment Background and Modeling Data

1. Health Risk Assessment

1.1 CONSTRUCTION HEALTH RISK ASSESSMENT
The Town of Yountville (Town) is preparing an addendum to the Envision General Plan Update Environmental Impact Report (Certified EIR) for the Yountville Commons project (project). The project site was formerly occupied by Yountville Elementary School in the Town of Yountville, Napa County. The project site is surrounded by condominiums to the north, Yount Street and single-family residences to the west, Finnell Road, multi-family residences, a hotel, and agricultural uses to the south, and Hopper Creek and townhouses to the east.

The project includes the demolition of the existing school administration building and paved areas to construct up to 150 multi-family units, including at least 42 affordable units and up to 108 market-rate units.

Multi-family units would be distributed across 15 three-story buildings. The project would also include 1,500 square feet of retail or restaurant space on the ground floor of three multi-family buildings; 1,500 square feet of other local serving businesses; and 8,000 square feet of civic or commercial space in three two-story buildings along Yount Street. A variety of open space, recreation, and landscaping improvements throughout the project site would be included. The project would retain the two parking lots serving Town Hall and construct a new parking lot on the north side of the site adjacent to the Hopper Creek Condominiums.

Project would also provide off-site pedestrian improvements near the site, including reconstruction of sidewalks, construction of new crosswalks, and a speed table.

Project-related construction emissions are based on information provided by the Town and CalEEMod defaults. Construction was modeled to occur between April 2026 through April 2028 for an approximately 24-month duration (523 workdays), with 5 working days per week. The construction equipment mix used in the model reflects CalEEMod defaults for equipment use and activity durations. Construction activities would include demolition, site preparation, grading, building construction, paving, architectural coating, and finishing/landscaping. Construction was assumed to take place from 7:00 am to 4:00 pm, Monday through Friday, allowing for a 1-hour lunch break. The active construction and staging areas would be clearly marked, and construction fencing would be installed on the project site.

The latest version of the Bay Area Air District (Air District) CEQA Air Quality Guidelines recommends projects to evaluate the impacts of construction activities on nearby receptors (Air District 2022). The nearest receptors to the project site include residences as close as 25 feet surrounding the project site and worker receptors at the Bardessono Hotel and Spa approximately 65 feet to the southeast of the project site.

Because receptors, including sensitive receptors such as residents, are present in land uses near the project site, a site-specific construction Health Risk Assessment (HRA) has been prepared for the project. This HRA considers the health impact to nearby receptors (e.g., residents, workers) from construction emissions generated at the project site, including diesel equipment exhaust (diesel particulate matter or DPM) and particulate matter with an aerodynamic diameter equal to or less than 2.5 microns (PM2.5).

It should be noted that these health impacts are based on conservative (i.e., health protective) assumptions.

The United States Environmental Protection Agency (USEPA 2005) and the Office of Environmental Health Hazard Assessment (OEHHA 2015) note that conservative assumptions used in a risk assessment are intended to ensure that the estimated risks do not underestimate the actual risks. Therefore, the estimated risks may not necessarily represent actual risks experienced by populations at or near a site. The use of conservative assumptions tends to produce upper-bound estimates of exposure and thus risk.

For residential receptors, the following conservative assumptions were used:
 It was assumed that maximum-exposed off-site residential receptors stood outdoors and are subject to DPM at their residence for 24 hours per day, and approximately 350 construction days per year. In reality, California residents typically will spend on average 2 hours per day outdoors at their residences (USEPA 2011). This would result in lower exposures to construction related DPM emissions and lower estimated risk values.
 The calculated risk for infants from third trimester to age 2 is multiplied by a factor of 10 to account for early life exposure and uncertainty in child versus adult exposure impacts (OEHHA 2015).  The calculated risk for children age 2 to 16 is multiplied by a factor of 3 to account for early life exposure and uncertainty in child versus adult exposure impacts (OEHHA 2015).

For workers, the following conservative assumptions were used:
 It was assumed that maximum exposed receptors stood outside and are subject to DPM for 8 hours per weekday and approximately 250 construction days per year.

1.2 METHODOLOGY AND SIGNIFICANCE THRESHOLDS
For this HRA, the Air District’s significance thresholds were deemed to be appropriate and the thresholds that were used for this project are shown below:
 Excess cancer risk of more than 10 in a million
 Non-cancer hazard index (chronic or acute) greater than 1.0  Incremental increase in average annual PM2.5 concentration of greater than 0.3 μg/m3 The methodology used in this HRA is consistent with the following Air District and the OEHHA guidance documents:
 Air District. 2022. California Environmental Quality Act (CEQA) Air Quality Guidelines. April 2023.  Air District. 2016. Planning Healthy Places. May 2016.  OEHHA. 2015. Air Toxics Hot Spots Program Guidance Manual for the Preparation of Health Risk Assessments.

February 2015.

Health Risk Assessment Background and Modeling Data
Potential exposures to DPM and PM2.5 from project construction were evaluated for nearby receptors to the site. Pollutant concentrations were estimated using an air dispersion model, and excess lifetime cancer risks and chronic non-cancer hazard indexes were calculated. These risks were then compared to the significance thresholds used for this HRA.

1.3 CONSTRUCTION EMISSIONS
Construction emissions were calculated as average daily emissions in pounds per day, using the proposed construction schedule and the latest version of California Emissions Estimation Model, known as CalEEMod Version 2022.1. DPM emissions were based on the CalEEMod construction results, using maximum daily exhaust PM10 emissions. The PM2.5 emissions were taken from the CalEEMod output for maximum daily PM2.5 exhaust and fugitive dust.

Construction was modeled to occur between April 2026 through May 2027 for an approximately 13-month duration. The average daily emission rates from construction equipment used during the project were determined by multiplying the maximum daily emissions for each construction activity by the duration of that activity, within each calendar year, summing the total emissions from all construction activities for each calendar year, and dividing the summed total by the total construction workdays in that calendar year. The CalEEMod construction emissions output and emission rate calculations are provided in Attachment A.

1.4 DISPERSION MODELING
Air quality modeling was performed using the AERMOD atmospheric dispersion model to assess the impact of emitted compounds on sensitive receptors near the project. The model is a steady state Gaussian plume model and is an approved model by the Air District for estimating ground level impacts from point and fugitive sources in simple and complex terrain. The on-site construction emissions for the project were modeled as area sources. The off-site mobile sources were modeled as line sources. The model requires additional input parameters, including chemical emission data and local meteorology. Inputs for the construction emission rates are described in Section 1.3. Meteorological data obtained from the Air District for the nearest representative meteorological station (Napa College) with the five latest available years of complete meteorological data (2013-2017) were used to represent local weather conditions and prevailing winds.

The modeling analysis also considered the spatial distribution and elevation of each emitting source in relation to the sensitive receptors. To accommodate the model’s Cartesian grid format, direction-dependent calculations were obtained by identifying the Universal Transverse Mercator (UTM) coordinates for each source location. In addition, digital elevation model (DEM) data for the area were obtained and included in the model runs to account for complex terrain. An emission release height of 4.15 m was used as representative of the stack exhaust height for off-road construction equipment and diesel truck traffic, and an initial vertical dispersion parameter of 1.93 m was used, per California Air Resources Board (CARB) guidance (2000). For fugitive dust sources, an emission release height of 0 m was used to represent dust generated by ground disturbing activities and roadway dust re-entrainment.

To determine contaminant impacts during construction hours, the model’s Season-Hour-Day (HRDOW) scalar option was invoked to predict flagpole-level concentrations (1.5 m) for construction emissions generated between the hours of 7:00 am and 4:00 pm on weekdays with a 1-hour lunch break.

A unit emission rate of 1 gram per second was used for all modeling runs. The unit emission rates were proportioned over the poly-area sources for on-site construction emissions and divided between the line volume sources for off-site hauling emissions. The maximum modeled concentrations from the output files were then multiplied by the emission rates calculated in Attachment A to obtain the maximum flagpole-level concentrations at the maximum exposed receptor (MER) for each receptor type. The air dispersion modeling predicted the MER for each receptor type near the project site. These include the surrounding residences and worker receptors at the Bardessono Hotel and Spa approximately 65 feet to the southeast of the project site.

The MER locations are the receptor locations associated with the maximum predicted AERMOD concentrations resulting from the on-site construction emissions. The calculated on-site emission rates are approximately 3 to 4 orders of magnitude higher than the calculated off-site emission rates (see Attachment A). Therefore, the maximum concentrations associated with the on-site emission sources produce the highest overall MER concentrations and, consequently, highest calculated health risks.

The air dispersion model output for DPM and PM2.5 concentrations from the construction emission sources are provided in Attachment B.

1.5 RISK CHARACTERIZATION

1.5.1 Carcinogenic Chemical Risk
A threshold of ten in one million (10x10-6) has been established by OEHHA and recommended by the Air District and other air districts as a level posing no significant risk for exposures to carcinogens. Health risks associated with exposure to carcinogenic compounds can be defined in terms of the probability of developing cancer as a result of exposure to a chemical at a given concentration. The cancer risk probability is determined by multiplying the chemical’s annual concentration by its cancer potency factor (CPF), a measure of the carcinogenic potential of a chemical when a dose is received through the inhalation pathway. It is an upper-limit estimate of the probability of contracting cancer as a result of continuous exposure to an ambient concentration of one microgram per cubic meter (µg/m3) over a lifetime of 70 years.

Guidance from OEHHA recommends a refinement to the standard point estimate approach with the use of age-specific breathing rates and age sensitivity factors (ASFs) to assess risk for susceptible subpopulations such as children. For the inhalation pathway, the procedure requires the incorporation of several discrete variates to effectively quantify dose for each age group. Once determined, contaminant dose is multiplied by the cancer potency factor in units of inverse dose expressed in milligrams per kilogram per day (mg/kg/day)-1 to derive the cancer risk estimate. Therefore, to accommodate the unique exposures associated with the sensitive receptors, the following dose algorithm was used.

DoseAIR,per age group = (Cair × EF × [
BR
BW] × A × CF)
Where:

Health Risk Assessment Background and Modeling Data
DoseAIR = dose by inhalation (mg/kg-day), per age group Cair = concentration of contaminant in air (µg/m3)
EF = exposure frequency (number of days/365 days)
BR/BW = daily breathing rate normalized to body weight (L/kg-day) A = inhalation absorption factor (default = 1)
CF = conversion factor (1x10-6, µg to mg, L to m3)
The inhalation absorption factor (A) is a unitless factor that is only used if the cancer potency factor included a correction for absorption across the lung. The default value of 1 was used for this assessment. An exposure frequency (EF) of 0.96 is used for residential receptors to represent 350 days per year to allow for a two-week period away from home each year, and an EF of 0.68 was used for worker receptors to represent 250 workdays per year (OEHHA 2015). A fraction of time at home (FAH) factor applied to residential receptors.

The 95th percentile daily breathing rates (BR/BW), exposure duration (ED), age sensitivity factors (ASFs), and FAH for the various age groups are provided herein:

Age Groups BR/BW (L/kg-day) ED ASF FAH
Third trimester 361 0.25 10 0.85
0-2 age group 1,090 1.75 10 0.85
16-30 age group 335 2.00 1 0.73
For construction analysis, the exposure duration spans the length of construction (i.e., 2026 to 2028). To calculate the overall cancer risk, the risk for each appropriate age group is calculated per the following equation:

Cancer RiskAIR = DoseAIR × CPF × ASF × FAH ×
ED
𝐴𝐴𝐴𝐴
Where:

DoseAIR = dose by inhalation (mg/kg-day), per age group CPF = cancer potency factor, chemical-specific (mg/kg-day)-1 ASF = age sensitivity factor, per age group
FAH = fraction of time at home, per age group (for residential receptors only) ED = exposure duration (years)
AT = averaging time period over which exposure duration is averaged (30 years) The CPFs used in the assessment were obtained from OEHHA guidance. The excess lifetime cancer risks during the construction period to the maximally exposed resident were calculated based on the factors provided above. The cancer risks for each age group are summed to estimate the total cancer risk for each toxic chemical species. The final step converts the cancer risk in scientific notation to a whole number that expresses the cancer risk in “chances per million” by multiplying the cancer risk by a factor of 1x106 (i.e., 1 million). The calculated results are provided in Attachment A.

1.5.2 Non-Carcinogenic Hazards
An evaluation was also conducted of the potential non-cancer effects of chronic chemical exposures. Adverse health effects are evaluated by comparing the annual receptor level (flagpole) concentration of each chemical compound with the appropriate reference exposure limit (REL). Available RELs promulgated by OEHHA were considered in the assessment.

The hazard index approach was used to quantify non-carcinogenic impacts. The hazard index assumes that chronic sub-threshold exposures adversely affect a specific organ or organ system (toxicological endpoint).

Target organs presented in regulatory guidance were used for each discrete chemical exposure. To calculate the hazard index, each chemical concentration or dose is divided by the appropriate toxicity value. This ratio is summed for compounds affecting the same toxicological endpoint. A health hazard is presumed to exist where the total equals or exceeds one.

The chronic hazard analysis for DPM is provided in Attachment A. The calculations contain the relevant exposure concentrations and corresponding reference dose values used in the evaluation of non-carcinogenic exposures.

1.6 CONSTRUCTION HRA RESULTS
The calculated results are provided in Attachment A and the results are summarized in Table 1.

Source: Lakes AERMOD View, Version 13.0.0.

Note: Calculated Cancer risk using 2015 OEHHA HRA Guidance Manual. Bold = exceeds threshold. MER = maximally exposed receptor.

Cancer risk for the residential MER from project-related construction emissions was calculated to be approximately 29 in one million, which would exceed the 10 in one million significance threshold. Similarly, the annual average PM2.5 concentration at the residential MER would reach 0.35 µg/m3, which would exceed the Air District’s significance threshold of 0.3 µg/m3. Cancer risk for the worker receptor was calculated to be less than 1 in one million, which would not exceed the 10 in one million significance threshold.

For non-carcinogenic effects, the chronic hazard index identified for each toxicological endpoint equaled less than one for each identified receptor. Therefore, chronic non-carcinogenic hazards are within acceptable limits. Because the cancer risk and annual average PM2.5 concentration for the residential MER would exceed the Air District’s significance thresholds during project construction, the following Condition of Approval (COA) is proposed:

Health Risk Assessment Background and Modeling Data
Condition of Approval AIR-1 The Town of Yountville shall specify in the construction bid that the project construction contractor(s) and subcontractor(s) comply with the following requirements for all off-road equipment used over the entire duration of the construction activities at the site:

Use engines that meet either USEPA or California Air Resources Board (CARB) Tier 4 Final emission standards for engines that are greater than 25 horsepower. Ensure that all construction plans submitted to the Town of Yountville Planning and Building Department clearly show the selected emission reduction strategy for construction equipment over 25 horsepower.

If Tier 4 Final equipment is not available for use for the project for a specific piece of off-road construction equipment, documentation shall be provided to the Town demonstrating that such equipment is not available for the project. If Tier 4 Final equipment is not available, the construction contractor(s) and subcontractor(s) affected shall use Tier 4 Interim equipment instead. If Tier 4 Interim equipment is not available for use for the project for a specific piece of off-road construction equipment, documentation shall be provided to the Town demonstrating that such equipment is not available for the project. If Tier 4 Interim equipment is not available, the construction contractor(s) and subcontractor(s) affected shall use Tier 3 equipment outfitted with a level 3 diesel particulate filter instead.

COA AIR-1 would reduce the proposed project’s localized construction emissions at the residential MER, as shown in the following Table 2. This measure would require all construction equipment over 25 horsepower to meet Tier 4 Final emission standards. The results indicate that, with this COA, cancer risk and annual average PM2.5 concentration would be less than the Air District’s significance thresholds at the residential MER, and all other receptors would be less than the Air District’s significance thresholds during proposed project’s construction. Therefore, the proposed project would not expose nearby receptors to substantial concentrations of air pollutant emissions during construction with incorporation of COA AIR-1.

1.7 CUMULATIVE COMMUNITY HEALTH RISK
In addition to a project-level HRA, the Air District recommends assessing the potential cumulative impacts from sources of TACs within 1,000 feet of a project. For the cumulative analysis, the Air District maintains several tools and databases for identifying risks at a particular location. The existing TACs that the Air District recommends a cumulative analysis include permitted stationary sources, marine sources, roadway sources, rail sources, and highway sources. Risks from permitted stationary sources within 1,000 feet of the project site can be identified using the Air District’s Stationary Source Screening Map (Air District 2025a). Risks from roadway sources are released periodically from the Air District in the form of risk assessment screening tools (RAST), which were utilized in determining associated risks at the residential MER during proposed project construction (Air District 2025b). The residential MER was utilized in the cumulative community risk assessment as it represents the greatest impact to nearby receptors during project construction. No marine risks are shown in the cumulative HRA as no marine activities occur within 1,000 feet of the project site.

Table 3 summarizes the existing TAC source risks at the residential MER from project construction emissions with implementation of COA AIR-1 in combination with existing TAC sources within 1,000 feet of the project site. As shown therein, the proposed project’s construction emissions combined with existing TAC emissions within 1,000 feet do not exceed the Air District’s cumulative community health risk significance thresholds at the residential MER location with incorporation of COA AIR-1.
