coverage specified by Indian reservations in the state specific permit coverage areas below; any land held in trust by the United States for an Indian tribe; and any other areas which are Indian country within the meaning of 18
U.S.C. 1151.
III. Summary of Draft Permits Coverage under the draft permits will be limited to lagoon systems treating primarily domestic wastewater and will include two categories of coverage;
discharging lagoons DIS, and lagoons expected to have no discharge but with the potential to discharge NODIS. The effluent limitations for discharging lagoons are primarily based on the Federal Secondary Treatment Regulation 40 CFR part 133. However, if more stringent and/or additional effluent limitations were considered necessary to comply with applicable water quality standards, etc., those limitations and the basis for them are explained in the fact sheet and will be imposed by written notification to the permittee. Lagoon systems under the NODIS category are required to have no discharge except in accordance with the specific provisions of the permit e.g., bypass. Self-monitoring, operation and maintenance, routine inspection and other requirements are also included in the draft permits. Where tribes have Clean Water Act CWA section 401a1 certification authority, EPA
has requested certification that the draft permits comply with applicable provisions of the CWA and any currently approved tribal water quality standard, in accordance with processes outlined in 40 CFR part 124.
