d d UNDERSTANDING of NEED Proposal for Various Environmental Services Page 17 August 1, 2022 A -Tech understands that the City of Santa Ana is planning to award contract(s) to qualified firms for providing various environmental assessment services in support of its Capital Improvement Program and other projects. It is our understanding that the required services are divided into two separate categories: ■ Category I. Environmental Site Assessments (ESAs) ■ Category H. Hazardous Material Surveys Our approach for this as -needed contract is to designate a single point of contact to the City, who will be managing the daily tasks of awarded projects and ensuring delivery of high -quality products in a timely manner. A-Tech's project manager is available 24/7for responding to City's requests and will coordinate the project requirements with A -Tech Team and staff as soon as the task orders are available. A -Tech has utilized its 20 years of experience in conducting ESAs and Hazardous Material Surveys along with the RFP, Questions and Answers, and Amendments provided by the City to develop a general approach for successful completion of future projects. The scope of work and schedule for the example requested projects are provided in Section 2.0 of this proposal. The Phase I ESAs will be conducted in accordance with the "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process " published by the American Society for Testing and Materials (ASTM 1527-21). A-Tech's general approach for completion of a successful Phase I ESA includes: ■ A review of relevant background information such as the site location relative to major man-made and natural landmarks, and surrounding land use. A general review of the geologic, hydrogeologic, hydrologic and topographic conditions as they relate to potential pathways or migration conduits to and from the property. Topography will be noted to the extent visually or physically observed or determined from interviews, as well as the general topography of the area surrounding the Property. The physical setting evaluation will be made utilizing physical observations and the available United States Geological Survey (USGS) 7.5 Minute Topographic Map. ■ A review of oil and gas fields in the vicinity of the site. ■ A compilation of site history and previous land use based on a review of historic aerial photographs dating back to the 1940s, available historic topographic maps, available historic fire insurance maps, and available city directories. ■ A review of chain -of -title records to identify possible recorded environmental cleanup liens. ■ An assessment of the potential for the site to have been impacted by contaminants and/or vapor migration originating from off -site sources based on a review of federal, state, tribal, and local government agency records. ■ A review of local municipal records including building permits, and zoning and land use records.
