Description of Assessment: The PEA Report was prepared by Terraphase Engineering, Inc. for submittal to the DTSC. This PEA Report was prepared under the oversight of the DTSC in general accordance with the guidelines of the DTSC, as detailed in the PEA Guidance Manual. A review of historical information for the Site and previous environmental sampling identified the potential presence of environmental concerns. In order to evaluate these potential concerns in soil, Terraphase completed Phase I and Phase II due diligence investigations at the Site on behalf of the District in 2018 and 2019. Between several investigations previously conducted at the Site from 2008 to 2016 and Terraphase’s Phase II investigation performed in 2018, a total of 118 soil samples were collected at the Site and submitted for analysis at a California-certified analytical laboratory. The soil sample analytical results were screened using DTSC screening levels provided in DTSC’s Office of Human and Ecological Risk (HERO) Note 3 for residential soil and the United States Environmental Protection Agency’s Regional Screening Levels for residential soil. Based on the results of the PEA investigation, chemicals of potential concern have not been detected in soil at the Site at levels exceeding conservative generic risk-based screening values for residential land use and no further studies are required for the site.
