(a) This part sets forth the applicable Underground Injection Control (UIC) programs for each of the States, territories, and possessions identified pursuant to the Safe Drinking Water Act (SDWA) as needing a UIC program, including any Indian country geographically located within those States, territories, and possessions.

(b) The applicable UIC programs set forth in this part may be State-administered programs approved by EPA, Tribally-administered programs approved by EPA, or Federally-administered programs promulgated by EPA. In some cases, the applicable UIC program for a particular area may consist of a State-administered or Tribally-administered program applicable to some classes of wells and a Federally-administered program applicable to other classes of wells. Approval of a State or Tribal program is based upon a determination by the Administrator that the program meets the requirements of section 1422 or section 1425 of the SDWA, any other applicable provisions of this subpart, and the applicable provisions of 40 CFR parts 124, 144, 145 and 146. A Federally-administered program is promulgated in those instances where the State or Tribe has not submitted any program for approval or where the submitted program does not meet the minimum Federal statutory and regulatory requirements.

(c) In the case of each State or Tribal program approved by EPA pursuant to section 1422 of the SDWA, the relevant subpart describes the major elements of that program, including the relevant State or Tribal statutes and regulations, the Statement(s) of Legal Authority, the Memorandum of Agreement, and the Program Description. State or Tribal statutes and regulations that contain standards, requirements, and procedures applicable to owners or operators have been incorporated by reference pursuant to regulations of the Office of the Federal Register. Material incorporated by reference is available for inspection in the appropriate EPA Regional office, in EPA Headquarters, and at the National Archives and Records Administration (NARA). For information on the availability of this material at NARA, call (202) 741-6030, or go to: http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_locations.html. Other State or Tribal statutes and regulations containing standards and procedures that constitute elements of a State or Tribal program but do not apply directly to owners or operators have been listed but have not been incorporated by reference.

(d) In the case of any program promulgated under section 1422 for a State or Tribe that is to be administered by EPA, the relevant State or Tribal subpart makes applicable the provisions of 40 CFR parts 124, 144, 146, and 148, and any other additional requirements pertinent to the specific State or Tribal program.

(e) Regulatory provisions incorporated by reference (in the case of approved State or Tribal programs) or promulgated by EPA (in the case of EPA-administered programs), and all permit conditions or permit denials issued pursuant to such regulations, are enforceable by the Administrator pursuant to section 1423 of the SDWA.

(f) Class VI well owners or operators must comply with § 146.91(e) notwithstanding any State program approvals.
