The Leatl Agency is <br /> receiving this notice from DTSC because the project includes one or more of the <br /> following: groundbreaking activities, work in close proximity to a roadway, work in close <br /> proximity to mining or suspected mining or former mining activities, presence of site <br /> buildings that may require demolition or modifications, importation of backfill soil, and/or <br /> work on or in close proximity to an agricultural or former agricultural site. <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 mechanisms) 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 Unitatl 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 /> and along roadways throughout the state. ADL-contaminated soils still exist <br />
