Publish Date: 11/30/2019


EPA has formulated a draft permit for the LANL – Storm Water Individual Permit under the National Pollutant Discharge Elimination System (NPDES).  Development of the draft permit was based on a preliminary staff review by EPA, Region 6, and consultation with applicable States and/or Tribes.  The permit will become effective 30 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 public hearing is held requiring delay of the effective date.

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.  During the comment period, any interested person may request a Public Hearing by filing a written request which must state the issues to be raised.  A public hearing will be held when EPA finds a significant degree of public interest.
