SUPPLEMENTARY INFORMATION:

I. Background

The Drinking Water General Permit (DWGP) contains requirements similar to an individual permit and will authorize the discharge of process wastewater in accordance with the terms and conditions described therein. The fact sheet for the permit is provided for download concurrently with the permit and provides detailed information on the methodology used to develop effluent limitations, the specific geographic areas covered by the permits, monitoring schedules, inspection requirements, and other regulatory decisions or requirements in the permit.

II. Summary of Permit Coverage

The DWGP (DWG589XXX) provides coverage for drinking water treatment facilities in EPA Region 8 that discharge process wastewater to waters of the United States in Indian Country within the meaning of 18 U.S.C. 1151. A full description of the geographic scope of coverage is included in the public notice version of the permit.

The DWGP provides coverage for discharges of treated wastewater from drinking water treatment processes. Process flows contributing to the discharge include: Filter backwash, filter to waste, decanted lime sludge dewatering, influent screen backwash and/or miscellaneous wastewater sources associated with drinking water facility operation. Miscellaneous wastewater sources may include, but are not limited to: Processed potable water, disinfection of treatment plant pipelines and tanks, and overflow from holding tanks of treated water.

The EPA has identified drinking water treatment processes methods that do not qualify for coverage under the DWGP. The processes wastewaters not included in this general permit include: Batch regenerated potassium permanganate iron removal, sodium zeolite softening, nano filtration and reverse osmosis.

The DWGP contains two sets of effluent limitations: Primary effluent limitations that apply to all discharges, and supplemental effluent limitations that will apply to discharges on an individual basis as necessary to protect water quality. The effluent limitations were derived from technology based and water quality based effluent limitations as described in the fact sheet. The EPA will review a facility's Notice of Intent (NOI) to be covered under the DWGP and determine the need for implementation of the supplemental effluent limitations and corresponding self-monitoring requirements. The permittee will be notified of the applicable effluent limitations and monitoring requirements in the notification of coverage.

The following Tribes in EPA Region 8 have Clean Water Act § 401(a)(1) certification authority: The Assiniboine & Sioux Tribes, the Confederated Salish & Kootenai Tribes, the Northern Cheyenne Tribe, the Ute Mountain Ute Tribe, and the Southern Ute Indian Tribe. The EPA has requested certification from each of these Tribes that the DWGP complies with the applicable provisions of the Clean Water Act and their respective tribal water quality standards.

III. Other Legal Requirements

Economic Impact (Executive Order 12866): The EPA Office of Policy has determined that the issuance of these general permits is not a “significant regulatory action” under the terms of Executive Order 12866 (58 FR 51735 (October 4, 1993)) and is therefore not subject to formal Office of Management and Budget (OMB) review prior to proposal.

Paperwork Reduction Act: EPA has reviewed the requirements imposed on Start Printed Page 16260regulated facilities in these proposed general permits under the Paperwork Reduction Act of 1980, 44 U.S.C. 501, et seq. The information collection requirements of these permits have already been approved by the OMB in submissions made for the NPDES permit program under the provisions of the Clean Water Act.

Unfunded Mandates Reform Act: Section 201 of the Unfunded Mandates Reform Act (UMRA), Public Law 104-4, generally requires federal agencies to assess the effects of their “regulatory actions” defined to be the same as “rules” subject to the Regulatory Flexibility Act (RFA) on tribal, state, local governments and the private sector. Since the permit proposed is an adjudication, it is not subject to the RFA and is therefore not subject to the requirements of the UMRA.
