interim control of hazardous waste injection

interim control of hazardous waste injection Sec. 3020. (a) Underground Source of Drinking Water.—No hazardous waste may be disposed of by underground injection— (1) into a formation which contains (within one-quarter mile of the well used for such underground injection) an underground source of drinking water; or (2) above such a formation. The prohibitions established under this section shall take effect 6 months after the enactment of the Hazardous and Solid Waste Amendments of 1984 except in the case of any State in which identical or more stringent prohibitions are in effect before such date under the Safe Drinking Water Act. (b) Actions Under CERCLA.—Subsection (a) shall not apply to the injection of contaminated ground water into the aquifer from which it was withdrawn, if— (1) such injection is— (A) a response action taken under section 104 or 106 of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or (B) part of corrective action required under this title intended to clean up such contamination; (2) such contaminated ground water is treated to substantially reduce hazardous constituents prior to such injection; and (3) such response action or corrective action will, upon completion, be sufficient to protect human health and the environment. (c) Enforcement.—In addition to enforcement under the provisions of this Act, the prohibitions established under paragraphs (1) and (2) of subsection (a) shall be enforceable under the Safe Drinking Water Act in any State— (1) which has adopted identical or more stringent prohibitions under part C of the Safe Drinking Water Act and which has assumed primary enforcement responsibility under that Act for enforcement of such prohibitions; or (2) in which the Administrator has adopted identical or more stringent prohibitions under the Safe Drinking Water Act and is exercising primary enforcement responsibility under that Act for enforcement of such prohibitions. (d) The terms “primary enforcement responsibility”, “underground source of drinking water”, “formation” and “well” have the same meanings as provided in regulations of the Administrator under the Safe Drinking Water Act. The term “Safe Drinking Water Act” means title XIV of the Public Health Service Act. [42 U.S.C. 6939b]
