ll LKMEA, Based on our review of the Request for Proposals, KMEA fully understands the nature and scope of services requested by the City. As part of this solicitation for Various Environmental Services, the City wishes to retain a qualified consultant to provide: • Phase I ESAs • Phase II ESAs; and • Hazardous Materials Surveys to include LBP and Asbestos evaluations. Phase I ESAs (Al)— Anticipated Approach, Tasks. Deliverables and Special Considerations Our approach to conducting Phase I ESAs is in general accordance with the ASTM Standard E1527 and the U.S. EPA "All Appropriate Inquiry" (AAI) and consists of the following steps: • Attend a kick-off meeting with the client point of contact (City) to discuss the nature and scope of desired survey. • Identify the property location including address, parcel number and size of the target property. • Identify the site contacts and personnel familiar with the history of the site to conduct personal interviews. • Order the Environmental Data Resource (EDR) one -mile radius report pertinent to the target property. • Review pertinent and readily available historical documents such as historical aerial photographs, topographic maps, Sanborn Maps. • Review readily available and pertinent historical documents for evidence of potential environmental concerns for both surface and subsurface associated with prior land uses. • Following obtaining approval from the City, set up interviews with knowledgeable site owners/operators (current and former owners and occupants) including adjacent property owners and/occupants and applicable local government officials to identify historical operations conducted on the project site and adjacent properties. • Review readily available literature to assess the existing site geology, hydrology, hydrogeology and potential for chemical contaminant migration from offsite sources. This includes a review of available literature to identify the presence of water supply wells, and oil and gas wells within the one -mile radius of the target property. Emerging contaminants such as Per - and Polyfluoroalkyl Substances (PFAS) have become a topic of many due diligence investigations. The KMEA team is currently supporting its clients with in-depth evaluation of these contaminants at various sites it is investigating and has up- to-date, hands-on experience with survey methodologies and chemical characteristics and behavior of such contaminants in various types of media. KMEA will also explore the possible presence of such substances and their on -site migration potential from offsite sources, if any, during its review of available documents. In addition, other more conventional contaminants such as petroleum hydrocarbon contamination, i.e., from nearby retail gas station sites, dry cleaner sites, etc., will be considered during the document review process. Vapor intrusion has also become a focal point of environmental concern and a subject of much review and scrutiny as part of due diligence studies. Therefore, as a key component of our Phase I ESAs, attempts will also be made to identify offsite or on -site sources for vapor phase migration of contamination. The results of these findings are subsequently summarized in our Phase I ESA report. • Set up file review appointments with regulatory agencies to review the status of unauthorized release cases pertinent to establishments identified to pose a potential risk to the target property during review of the historic documents including the EDR report. • Conduct a site reconnaissance to document site conditions. This would typically consist of a site walk-through to evaluate the site conditions and identify areas with evidence of past or present environmental conditions of concern. Our site reconnaissance also consists of preparing a photo -documentation along with photo logs describing the site conditions and locations visited and surveyed. Inaccessible locations will be diligently marked and documented. A site map showing locations of relevant site features and conditions noted will also be prepared during our reconnaissance. For active facilities, pertinent operation permits and applicable licenses and agency site inspection records will be reviewed and photocopied or documented, where feasible. This includes documents such as business license, air compliance permit, waste inventory and management records among others, where applicable. • Provide a verbal summary of our findings to the City immediately following completion of review of available pertinent documents and site reconnaissance results. This is to provide the City with critical data needed in order to facilitate making informed decisions regarding a property transaction in an accelerated fashion. • Prepare a Phase I ESA Report. The report will provide concise information from the research conducted and will include a discussion of our findings from our survey and site reconnaissance. The report will outline the Recognized Environmental City of Santa Ana Page 6 June 5, 2018 Various Environmental Services RFP NO.; 18-043
