ARARs appropriate to this project will be determined by DTSC. <br /> 1.5.1 Chemical-Specific ARARs <br /> Groundwater Quality <br /> 1. Federal Primary Drinking Water Standards (40 Code of Federal Regulations (CFR) Part 141) <br /> under the Safe Drinking Water Act (SDWA). Chemical-specific drinking water standards <br /> have been promulgated under Section 1412 of the federal Safe Drinking Water Act (42 <br /> U.S.C. § 300g-1). Maximum Contaminant Levels (MCLS) are enforceable standards for <br /> public drinking water systems. In accordance with the National Contingency Plan("NCP"), <br /> MCLS, or federal Maximum Contaminant Level Goals (MCLGs) are generally used as <br /> baseline relevant and appropriate standards for groundwater. <br /> 2.

The Water Code authorizes the State Water Resources Control Board (SWRCB) and <br /> Regional Water Quality Control Boards (RWQCBs)to: <br /> • establish Water Quality Control Plans to determine beneficial uses and standards to <br /> protect surface and groundwater quality <br /> • issue permits for discharges to land or surface water or groundwater that could affect <br /> water quality (including NPDES permits) <br /> is • to take enforcement action to protect water quality <br /> 9 <br /> 25970318.PGS 15 November 2000 <br />
