Bat Nha Buddhist Meditation Center MND I City of Santa Ana Planning Division 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. • Demolition and Construction-Period Mass Emissions. The demolition and 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 CaIEEMod land use emissions model and compared to applicable SCAQMD daily emissions thresholds to determine significance. IN 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. ® 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 CalEEMod 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 CARB, OPR and SCAQMD. * 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. Our local noise engineer is certified by the INCE and has conducted numerous analyses for projects involving re-development and school projects that are adjacent to residential and sensitive (church/school) uses. Existing residences, churches and a preschool/daycare are located immediately adjacent to the project site, which could be impacted by noise from project demolition, construction and operation. Additionally, on-site temple and meditation uses adjacent to Sullivan Street are also considered to be noise-sensitive and could be impacted by project traffic. To identify the existing ambient noise environment in the project area, up to four short-term (up to 1 hour in duration) ambient noise measurements will be conducted at noise-sensitive locations in and around the project site. The noise measurements will be conducted using equipment and methods as proscribed by the American National Standard Institute and consistent with the standards of the practice for community noise analysis. Using the noise measurements as a baseline, potential construction noise impacts on nearby noise-sensitive land uses will be evaluated based on construction equipment data to be provided by the project applicant and noise modeling methods developed by the Federal Highway Administration (FHWA). Long-term (operational) noise effects from the project will also be addressed and will include evaluation of on-site activity noise levels and the ability of the noise to effect surrounding uses. Using traffic data provided by the project traffic consultant, traffic noise along roadways surrounding the project site will be modeled (using FHWA Traffic Noise Model version 2.5) for existing, future and future-with-project conditions.
