Summary

The EPA has proposed an NPDES Statewide General Permit for storm water discharges from Tribal municipal separate storm sewer systems (MS4s) located in urbanized areas in the States of New Mexico and Oklahoma. The proposed permit offers discharge authorization to regulated MS4s within the boundaries  of the Bureau of the Census-designated 2000, 2010, and 2020 Urbanized Areas and any other MS4s designated by EPA as needing a MS4 permit.  Development of the draft permit was based on a preliminary staff review by EPA, Region 6, Stakeholders and consultation with applicable States and/or Tribes.  The permit will become effective 60 days after the close of the comment period unless:

A.     Applicable State and/or Tribe denies certification under section 401 of the Clean Water Act, or requests an extension for certification prior to the date.

B.     Comments received by deadlines listed for individual Public Notice(s) below in accordance with 40 CFR §124.20, warrant a public notice of EPA's final permit decision. 

C.     A virtual public hearing will be held.  More information on the date and how to participate will be posted on the EPA public notices web page at  https://www.epa.gov/publicnotices at least 30 days prior to the virtual public hearing. 

EPA's comment and public hearing procedures may be found at 40 CFR §124.10 and §124.12.  The comment period during which written comments on the draft permits may be submitted is noted for the individual Public Notice.  

EPA will notify each person who has submitted comments or requested notice of the final permit decision.  A final permit decision means a final decision to issue, deny, modify, revoke or reissue, or terminate a permit.  Any person who filed comments on or participated in a public hearing on the draft permit may appeal the Agency’s final permit decision.  However, the request must be submitted within 30 days of the date of the final permit decision and be in accordance with the requirements of 40 §CFR 124.19.

Further information regarding the administrative record may be requested from the EPA contact above  at the above address .
