APPENDIX J <br /> SUMMARY OF MAJOR REGULATORY SOURCES OF <br /> CLEANUP GOALS <br /> J.1 THE SAFE DRINKING WATER ACT (40 USC 300) <br /> This act promulgated National Primary Drinking Water Regulations (40 CFR Part 141) and <br /> National Secondary Drinking Water Regulations (40 CFR Part 143). Primary maximum contaminant limits <br /> (MCLs) are enforceable standards for contaminants in public drinking water supply systems. They <br /> consider health factors, economic feasibility, and technical feasibility of removing a contaminant from a <br /> water supply system. Secondary MCLs are intended as guidelines to protect the public welfare. <br /> Contaminants covered are those that may adversely affect the aesthetic quality of drinking water, such <br /> as taste, odor, color, and appearance, and may deter public acceptance of drinking water provided by <br /> public water systems. <br /> Maximum contaminant limit goals (MCLGs) exist for several organic and inorganic compounds <br /> found in drinking water. MCLGs are non-enforceable guidelines that consider only health factors. <br /> During the Feasibility Study, MCLs or MCLGs may be used to determine remedial actions for <br /> groundwater and surface waters that are current or potential sources of drinking water. The NCP <br /> requires that MCLGs set at levels above zero (i.e., non-zero MCLGs) be attained during a CERCLA <br /> cleanup. In cases where the MCLG equals zero, the corresponding MCL is applicable (40 CFR 300.430 <br /> (e)(2)(i)(13) and (C)). <br /> Underground injection control regulations (40 CFR Parts 144-147) provide for the protection of <br /> underground sources of drinking water. These may apply if remedial design includes reinjection of <br /> water. <br /> J.2 CLEAN WATER ACT (33 USC 1251-1376) <br /> This act sets standards and requirements for pollutant discharge. The National Pollutant <br /> Discharge Elimination System (NPDES) (40 CFR Parts 122 and 125) requires permits for the discharge of <br /> pollutants from any point source into the waters of the United States. General Pre Treatment <br /> Regulations are enforceable standards promulgated under 40 CFR Part 403 for discharge to a publicly <br /> owned treatment works (POTW). They can be ARARs if groundwater remediation results in discharge to <br /> a POTW. <br /> J.3 U.S. WATER OUAUTY CRITERIA, 1986 <br /> The water quality criteria are standards for ambient surface water quality. The water quality <br /> criteria apply to specific bodies of water and typically are set by the states (40 CFR Part 131). They are <br /> not rules and they do not have regulatory impact. Rather, these criteria present guidance on the <br /> environmental effects of pollutants that can be a useful reference in environmental work. These water <br /> quality criteria may be included as 'to be considered' conditions when setting cleanup goals. <br /> J.4 RESOURCE CONSERVATION AND RECOVERY ACT <br /> For RCRA requirements to be applicable or relevant and appropriate to CERCLA actions, a <br /> RCRA hazardous waste or a waste sufficiently similar to a RCRA hazardous waste must be present at the <br /> site. A review of site records and information may help determine if a RCRA hazardous waste is present. <br /> J-1 <br />
