The Academy Charter High School MND I City of Santa Ana Planning Division produce fugitive glare. A qualitative assessment of the impacts from new lighting and glare will be prepared, and mitigation measures will be identified if necessary, which may Include design measures to minimize spill light and glare. Air Quality Impact and GHG Analysis The air quality and GHG emissions assessment will be prepared consistent with the technical requirements and methodologies outlined In SCAQMD's CEQA Air Quality Handbook (as updated per the revisions posted on the SCAQMD website), Localized Significance Threshold Methodology for CEQA Evaluations, and Particulate Matter (PM) 2.5 Significance Thresholds and Calculation Methodology guidance documents. For the evaluation of GHG emissions and climate change, specific methodologies and thresholds will be developed based on the latest information made available by the California Air Resources Board (ARB), Governor's Office of Planning and Research (OPR) and SCAQMD at time of project initiation. The air quality and climate change assessment will consist of the following: • Regulatory Setting and Existing Air Quality Conditions. The project site is located within the SCAQMD Source Receptor Area No. 20 (Central Orange County). The regulatory setting will include a summary of all pertinent statutes and regulations, including the federal Clean Air Act, California and National Ambient Air Quality Standards, and SCAQMD Air Quality Management Plan (AQMP). The existing conditions will describe ambient air quality data from the Anaheim-Pampas Lane ambient air monitoring station. The local air quality conditions will be compared to national and state ambient air quality standards. • Construction-Period Mass Emissions. The construction emissions inventory will include combustion emissions related to equipment operation; fugitive dust emissions related to demolition, site preparation and earthmoving activities; mobile (tailpipe) emissions related to construction worker and haul truck trips; and reactive organic compound emissions related architectural coatings application and asphalt pavement. The emissions inventory will be compiled on a daily basis and compared to SCAQMD regional and localized emissions thresholds to determine significance. ® Operations-Period Mass Emissions Analysis. The operations emissions inventory will include mobile source emissions related to project-generated traffic (as identified by the traffic impact study), as well as stationary source emissions related to energy demand (i.e., electricity consumption). Emissions will be compiled using the CalEEMod land use emissions model and compared to applicable SCAQMD daily emissions thresholds to determine significance. • Localized Carbon Monoxide Concentration Analysis. Using the California Department of Transportation CO Protocol, this analysis will evaluate the degree to which project-related traffic volumes have the potential to effect local carbon monoxide (CO) concentrations. Potential impacts will be evaluated utilizing the CALINE4 dispersion model and EMFAC 2011 emissions factors at up to eight intersection locations. a Potential for Health Risk Impacts. Impacts related to toxic air contaminant emissions during short-term construction and long-term operations will be evaluated qualitatively. • Climate Change/GHG Emissions. Project-related GHG emissions will be estimated using the CaIEEMod software program. ICF will analyze the project's direct GHG emissions related to construction activities and project-related trips, as well as indirect GHG emissions associated with electricity usage. Significance criteria will be developed based on current guidance from CARE, OPR and SCAQMD. e Consistency with AQMP. The analysis will evaluate the project's consistency with the SCAQMD's 2007 AQMP in accordance with the procedures set forth by the SCAQMD. Noise Impact Study ICF will conduct a noise analysis for the proposed project in accordance with CEQA requirements to evaluate potential impacts to existing and future noise-sensitive land uses.
