Water Pollution Control (Section 106) Grants

Environmental Protection Agency

Deadline varies based on individual grants. Section 106 of the Clean Water Act (CWA) authorizes EPA to provide financial assistance to states and eligible interstate agencies to establish and administer programs for the prevention, reduction, and elimination of water pollution. In 1987, Congress amended section 518(e) of the CWA to include provisions that allow EPA to treat an Indian tribe in a manner similar to a state (i.e., treatment in a manner similar to a state, or TAS) for the purpose of providing Section 106 funding.

Funding Amount
Matching Funds
Yes, By regulation, the maximum federal share is 95 percent, and tribes are required to provide a 5 percent match. However, EPA may reduce or eliminate the share of matching funding if a tribe can show that fulfilling the 5 percent match requirement would cause undue hardship.
To be eligible, a tribe must meet the following requirements:

Be federally recognized by the Secretary of the Interior.
Have a governing body carrying out substantial governmental duties and powers.
Have legal authority and jurisdiction over tribal lands.
Have the capability to carry out functions to be exercised in a manner consistent with the terms and purposes of the CWA and all applicable regulations.
Submit an application to EPA and obtain TAS approval for the Section 106 grant program.
