Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183 products, and landscape maintenance equipment associated with the development of the proposed project. Energy source emissions would be generated as a result of electricity and natural gas usage associated with the proposed project. Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions. Emissions associated with each source are detailed in Table 2, Project -Generated Operational Emissions.

No No No No No No Notes: 1. Emissions were calculated using CalEEMod version 2022.1 and are based on 7,000 square feet building area as a conservative analysis. 2. The numbers may be slightly off due to rounding. Source: Refer to Attachment A for assumptions used in this analysis. As shown in Table 2, the total operational emissions for both summer and winter would not exceed established SCAQMD thresholds. Therefore, impacts in this regard would be less than significant. Air Quality Health Impacts Adverse health effects induced by criteria pollutant emissions are highly dependent on a multitude of interconnected variables (e.g., cumulative concentrations, local meteorology and atmospheric conditions, and the number and character of exposed individual [e.g., age, gender]). In particular, 03 precursors, VOCs, and NOx, affect air quality on a regional scale. Health effects related to 03 are therefore the product of emissions generated by numerous sources throughout a region. Existing models have limited sensitivity to small changes in criteria pollutant concentrations, and, as such, translating project -generated criteria pollutants to specific health effects or additional days of nonattainment would produce meaningless results. In other words, the project's less than significant increases in regional air pollution from criteria air pollutants would have nominal or negligible impacts on human health. As noted in the Brief of Amicus Curiae by the SCAQMD (April 6, 2015) for Sierra Club vs. County of Fresno, the SCAQMD acknowledged it would be extremely difficult, if not impossible to quantify health impacts of criteria pollutants for various reasons including modeling limitations as well as where in the atmosphere air pollutants interact and form. Further, as noted in the Brief of Amicus Curiae by the San Joaquin Valley Air Pollution Control District (SJVAPCD) (April 13, 2015) for the Sierra Club vs. County of Fresno, SJVAPCD acknowledged that currently available modeling tools are not equipped to provide a meaningful analysis of the correlation between an individual development project's air emissions and specific human health impacts.
