For analytical purposes, emissions associated with peak demolition, site preparation, and grading activities are considered for purposes of LSTs since this phase represents the maximum localized emissions that would occur. The Project’s construction activities could disturb a maximum of approximately 1 acre per day for demolition, 3.5 acres per day for site preparation, and 2.5 acres per day for grading activities. Any other construction phases of development would result in lesser emissions and consequently lesser impacts than what is disclosed herein. As such, Table 6 presents thresholds for localized construction and operational emissions.

The SCAQMD has established that impacts to air quality are signiffcant if there is a potential to contribute or cause localized exceedances of the federal and/or state ambient air quality standards (National Ambient Air Quality Standards (NAAQS)/California Ambient Air Quality Standards (CAAQS). Collectively, these are referred to as LSTs. The SCAQMD established LSTs in response to the SCAQMD Governing Board’s Environmental Justice Initiative I-43. LSTs represent the maximum emissions from a project that will not cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard at the sensitive receptor. The SCAQMD states that lead agencies can use the LSTs as another indicator of signiffcance in its air quality impact analyses. It should be noted that SCAQMD also states that Projects that are statutorily or categorically exempt under CEQA would not be subject to LST analyses. Receptors in the Project study area are described below and shown in Exhibit 2. Localized air quality impacts were evaluated at sensitive receptor land uses nearest the Project site. All distances are measured from the Project site boundary to the outdoor living areas (e.g., backyards) or at the building façade, whichever is closer to the Project site. • Location R1 represents the existing residence at 2246 South Van Ness Avenue, approximately 149 feet northwest of the Project site. • Location R2 represents the existing residence at 2335 South Van Ness Avenue, approximately 223 feet north of the Project site. 3 The purpose of SCAQMD’s Environmental Justice program is to ensure that everyone has the right to equal protection from air pollution and fair access to the decision-making process that works to improve the quality of air within their communities. Further, the SCAQMD defines Environmental Justice as “…equitable environmental policymaking and enforcement to protect the health of all residents, regardless of age, culture, ethnicity, gender, race, socioeconomic status, or geographic location, from the health effects of air pollution.”
