Why comply with ARARs?
Section 121(d) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA), requires attainment of federal and state applicable or relevant and appropriate requirements (ARARs). Subpart E, Section 300.400(g) “Identification of applicable or relevant and appropriate requirements,” of the National Oil and Hazardous Substance Pollution Contingency Plan (NCP) (55 FR 8666) describes the process for attaining these ARAR requirements.
