RFP #24-038A: On-Call Environmental Review Services for C HAM B E RS the Housing Division City of Santa Ana GROUP the SCAQMD and utilizes the SCAQMD CEQA Handbook as the guidance document for the environmental review of plans and development proposals within its jurisdiction. Vista Environmental's approach used for air quality analyses are dependent on if it is to be prepared for CEQA, NEPA, or Caltrans standards but typically includes identifying the air quality setting, obtaining the criteria pollutant concentrations from the nearest monitoring station, providing a summary of all applicable air quality regulations, identifying the applicable thresholds of significance, evaluating and quantifying regional criteria pollutant emissions from construction and operations through use of California Emissions Estimator Model® (CalEEMod), evaluating localized criteria pollutant concentrations through use of SCAQMD Look-Up Tables or through use of AERMOD, providing an odor analysis that identifies potential odor sources and sensitive receptors that may be impacted, and determining if any thresholds have been exceeded and,if necessary,providing mitigation to reduce impacts to less than significant levels. The approach used for GHG emissions analyses typically includes identification of GHG pollutants and their impacts to climate change, identification of applicable plans, policies and regulations and thresholds of significance, evaluation, and quantification of GHG emissions from construction and operations through the use of CalEEMod,determination of any thresholds have been exceeded, and if necessary develop mitigation to reduce impacts to less than significant levels,and provide a consistency analysis to determine if the project would conflict with any applicable plan for reducing GHG emissions. Noise Impact Analysis: Vista Environmental's approach used for noise analyses typically includes identifying noise sources in the project study area, obtaining noise measurements of the existing ambient noise levels in the vicinity of the project site,evaluating construction-related noise impacts at the nearby sensitive receptors through use of Federal Highway Administration's (FHWA) Roadway Construction Noise Model (RCNM), utilizing FHWA's RD-77-108 or TNM noise models to model traffic noise increases created by the project, utilizing reference noise measurements and standard drop-off rates or the SoundPlan model to analyze noise impacts from non-transportation noise sources, and determining if any thresholds have been exceeded and,if necessary,providing mitigation to reduce impacts to less than significant levels. Phase I ESA (Converse) Converse will generally follow the standard practices of the American Society for Testing Materials(ASTM) Phase I ESA Process (Standard: E1527-13) and HUD Guidelines. The ASTM Standard E1527-13 is intended to satisfy one of the requirements to qualify for the Landowner Liability Protections (LLP) within the scope of the Comprehensive Environmental Response,Compensation and Liability Act(CERCLA),that is,the practices that constitute all appropriate inquiry (AAI, 40 CFR Part 312) into the previous ownership and uses of the property consistent with good commercial or customary practice.The following Scope of Services is proposed: 1. Review of regulatory agency records, aerial photographs, fire insurance maps, city directories, building permits, United States Geological Survey(USGS)topographical maps and other non-standard historical sources. 2. Visual survey of property and adjacent sites for indications of potential for contamination or contamination generators. 3. A reasonable attempt will be made to interview the owner(s), site manager(s), and major occupant(s), and to contact State or local government officials. 4. Prepare report signed by an Environmental Professional for electronic submittal. Phase II ESA and Soil Testing (Converse) The objectives of a Phase II investigation are to:evaluate the likelihood that potentially hazardous materials are present at the site;assess the nature and concentrations of the chemical compounds;assess the vertical and horizontal extent of impacted soil through testing, as well as the impact to groundwater; determine if the subject property will require some form of remediation and evaluate the most feasible remedial alternative to remediate the site. The scope of services for a Phase II investigation is typically based on the results of a Phase I ESA and/or other Phase II investigations. Phase II investigations may include the following:a Geophysical Survey,collection and testing of soil,soil vapor, indoor air, and/or groundwater samples,field screening of samples, and/or laboratory analysis of samples.
