Hazelton Department <br /> Stockton, California 95205 <br /> ifunderburg(c�sigov.org <br /> MITIGATED NEGATIVE DECLARATION FOR PA-1900263 (SA) — DATED MARCH 19, <br /> 2020 (STATE CLEARINGHOUSE NUMBER: 2020039063) <br /> Dear Mr. Girardi: <br /> The Department of Toxic Substances Control (DISC) received a Mitigated Negative <br /> Declaration (MND) for PA-1900263 (SA). The proposed project is a site approval of a <br /> truck and trailer parking facility, on a 2.3 acre parcel over two phases. Phase 1 will be <br /> unmanned and includes utilizing the existing paved area for the parking of ten trucks <br /> and nine trailers. Phase 2 includes additional surfacing for up to ten additional trucks <br /> and up to nine additional trailers. In addition, Phase 2 proposes to convert an existing <br /> 1,445 square foot house to an office. <br /> DTSC recommends that the following issues be evaluated in the MND Hazards and <br /> Hazardous Materials section: <br /> 1. The MND should acknowledge the potential for historic or future activities on or <br /> near the project site to result in the release of hazardous wastes/substances on <br /> the project site. In instances in which releases have occurred or may occur, <br /> further studies should be carried out to delineate the nature and extent of the <br /> contamination, and the potential threat to public health and/or the environment <br /> should be evaluated. The MND should also identify the mechanism(s) to initiate <br /> any required investigation and/or remediation and the government agency who <br /> will be responsible for providing appropriate regulatory oversight. <br /> 2. Refiners in the United States started adding lead compounds to gasoline in the <br /> 1920s in order to boost octane levels and improve engine performance. This <br /> practice did not officially end until 1992 when lead was banned as a fuel additive <br /> in California. Tailpipe emissions from automobiles using leaded gasoline <br /> contained lead and resulted in aerially deposited lead (ADL) being deposited in <br /> t> Printed on Recycled Paper <br />
