16558-03 AQ & GHG Assessment 8 Warner Avenue Footlab • Location R3 represents a commercial building located at 417 West Warner Avenue, approximately 102 feet north of the Project site. • Location R4 represents the Esqueda Elementary School located at 2240 South Main Street, approximately 239 feet northeast of the Project site. • Location R5 represents the Las Gueritas Mexican restaurant located at 230 West Warner Avenue, approximately 89 feet east of the Project site. • Location R6 represents the Tibbetts Paint store located at 2337 South Birch Street, approximately 78 feet east of the Project site. • Location R7 represents Syco Enterprise, Inc. shopping service warehouse located at 500 West Warner Avenue, approximately 63 feet west of the Project site. The SCAQMD recommends that the nearest sensitive receptor be considered when determining the Project’s potential to cause an individual or cumulatively signiffcant impact. The nearest land use where an individual could remain for 24 hours to the Project site has been used to determine localized construction and operational air quality impacts for emissions of PM10 and PM2.5 (since PM10 and PM2.5 thresholds are based on a 24-hour averaging time). The nearest residential home is represented by R1, located at 2246 South Can Ness, approximately 149 feet (45 meters) northwest of the Project site. As such, for evaluation of localized PM10 and PM2.5, a 45-meter distance will be used. As previously stated, and consistent with LST Methodology, the nearest industrial/commercial use to the Project site is used to determine construction and operational LST air impacts for emissions of NOX and CO as the averaging periods for these pollutants are shorter (8 hours or less) and it is reasonable to assume that an individual could be present at these sites for periods of one to 8 hours. The Syco Enterprise, Inc. shopping service warehouse is the nearest commercial/industrial use and is located at 500 West Warner Avenue, approximately 63 feet (19 meters) west of the Project site. It should be noted that the LST Methodology explicitly states that “It is possible that a project may have receptors closer than 25 meters. Projects with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters (18).” As such, for evaluation of localized NOX and CO, a 25-meter distance will be used. Table 7 identiffes the localized impacts at the nearest receptor location in the vicinity of the Project. Outputs from the model runs for construction LSTs are provided in Appendix 1. For analytical purposes, emissions associated with peak demolition, site preparation, and grading activities are considered for purposes of LSTs since these phases represent the maximum localized emissions that would occur. Any other construction phases of development that overlap would result in lesser emissions and consequently lesser impacts than what is disclosed herein. As shown in Table 7, emissions resulting from the construction will not exceed the numerical thresholds of signiffcance established by the SCAQMD for any criteria pollutant. Thus, a less than signiffcant impact would occur for localized Project-related construction-source emissions and no mitigation is required.
