Water pollution control grants are awarded to assist Tribes and Intertribal Consortia in administering programs for the prevention, reduction, and elimination of water pollution, including programs for the development and implementation of ground-water protection strategies.

(c) Associated program requirements. Program requirements for water quality planning and management activities are provided in 40 CFR part 130.

§ 35.582 Definitions.

Federal Indian reservation. All land within the limits of any Indian reservation under the jurisdiction of the United States Government, notwithstanding the issuance of any patent, and, including rights-of-way running through the reservation.

§ 35.583 Eligible recipients.

A Tribe, including an Intertribal Consortium, is eligible to receive a section 106 grant if EPA determines that the Indian Tribe or each member of the Intertribal Consortium meets the requirements for treatment in a manner similar to a State under section 518(e) of the Clean Water Act (see 40 CFR 130.6(d)).

§ 35.585 Maximum federal share.

(a) The Regional Administrator may provide up to 95 percent of the approved work plan costs for Tribes or Intertribal Consortia establishing a section 106 program. Work plan costs include costs of planning, developing, establishing, improving or maintaining a water pollution control program.

(b) The Regional Administrator may increase the maximum federal share if the Tribe or Intertribal Consortium can demonstrate in writing to the satisfaction of the Regional Administrator that fiscal circumstances within the Tribe or within each Tribe that is a member of an Intertribal Consortium are constrained to such an extent that fulfilling the match requirement would impose undue hardship.

§ 35.588 Award limitations.

(a) The Regional Administrator will only award section 106 funds to a Tribe or Intertribal Consortium if:

(1) All monitoring and analysis activities performed by the Tribe or Intertribal Consortium meets the applicable quality assurance and quality control requirements in 2 CFR 1500.12.

(2) The Tribe or each member of the Intertribal Consortium has emergency power authority comparable to that in section 504 of the Clean Water Act and adequate contingency plans to implement such authority.

(4) The Tribe or Intertribal Consortium agrees to include a discussion of how the work performed under section 106 addressed water quality problems on Tribal lands in the annual report required under § 35.515(d).

(5) After an initial award of section 106 funds, the Tribe or Intertribal Consortium shows satisfactory progress in meeting its negotiated work plan commitments.

(b) A Tribe or Intertribal Consortium is eligible to receive a section 106 grant or section 106 grant funds even if the Tribe or each of the members of an Intertribal Consortium does not meet the requirements of section 106(e)(1) and 106(f)(1) of the Clean Water Act.
