II. Background

EPA made this determination under the authority of Section 9 of the WIPP Land Withdrawal Act (WIPP LWA). (Pub. L. 102-579 and 104-201.) Section 9(a)(1) of the WIPP LWA requires that, as of the date of the enactment of the WIPP LWA, DOE shall comply with respect to WIPP with (1) regulations for the management and storage of radioactive waste (40 CFR part 191, subpart A); (2) the Clean Air Act; (3) the Solid Waste Disposal Act; (4) the Safe Drinking Water Act; (5) the Toxic Substances Control Act; (6) the Comprehensive Environmental Response, Compensation, and Liability Act; and (7) all other applicable Federal laws pertaining to public health and safety or the environment. Section 9(a)(2) of the WIPP LWA requires DOE biennially to submit to EPA documentation of continued compliance with the laws, regulations, and permit requirements set forth in Section 9(a)(1). (DOE must also submit similar documentation of compliance with the Solid Waste Disposal Act to the State of New Mexico.) Section 9(a)(3) requires the Administrator of EPA to determine on a biennial basis, following the submittal of documentation of compliance by the Secretary of DOE, whether the WIPP is in compliance with the pertinent laws, regulations, and permit requirements, as set forth at Section 9(a)(1).

We determined that for the period 2004 to 2006, the DOE-submitted documentation showed continued compliance with 40 CFR part 191, subpart A, the Clean Air Act, the Safe Drinking Water Act, the Toxic Substances Control Act, and the Comprehensive Environmental Response, Compensation, and Liability Act. With respect to other applicable Federal laws pertaining to public health and safety or the environment, as required by Section 9(a)(1)(G), DOE's documentation also indicates that DOE was in compliance with the Clean Water Act, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and certain statutes under the jurisdiction of the Department of the Interior.

This determination is not in any way related to, or a part of, our certification decision regarding whether the WIPP complies with EPA's disposal regulations for transuranic radioactive waste at 40 CFR part 191.

Dated: May 31, 2007.

Stephen L. Johnson,

Administrator.
