City of Pleasanton—Vineyard Avenue Residential Project 15183 Consistency Checklist Consistency Checklist 103 (ASTM), RECs are defined as “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property due to a release to the environment; under conditions indicative of a release to the environment or under conditions that pose a material threat of future release.” The EPA provides a list of data resources that provide information regarding the facilities or sites identified as meeting the “Cortese List” requirements, pursuant to Government Code 65962.5. The project site is located on DTSC’s Hazardous Waste and Substances Site List, which is a component of the Cortese List.15 However, the on-site entry is related to a school investigation associated with the existing site zoning and did not identify any contaminants of concern. Therefore, further action related to the listing is not required. The other components of the Cortese List include the list of leaking underground storage tank sites from the State Water Resources Control Board’s (SWRCB) GeoTracker database, the list of solid waste disposal sites identified by the SWRCB, and the list of active Cease and Desist Orders (CDOs) and Cleanup and Abatement Orders (CAOs) from the SWRCB. The project site is not located on any of the aforementioned components of the Cortese List.16 Therefore, the project site is not anticipated to contain hazardous materials, and MM HAZ-2 would not apply. In addition, the Phase I ESA prepared for the proposed project included a review of a prior Phase II ESA conducted for the project site in 2000. Because the project site had been used as grazing land and an orchard for decades, the Phase II ESA was conducted to assess the potential presence of residual organochlorine pesticides (OCPs), chlorinated herbicides, and metals within the project site. The scope of the Phase II ESA included drilling 13 borings to a total depth of six feet bgs and collection of samples at depths of 1.5, 3.5, and six feet bgs. According to the Phase I ESA prepared for the proposed project, the results of the previously conducted Phase II ESA indicated that on-site pesticides and herbicides were not detected above laboratory reporting limits. Overall, RECs were not identified for the project site. Therefore, the proposed project would not result in any peculiar effects that would require further CEQA review related to creating a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions 15 Department of Toxic Substances Control.
