TXG330000 Final General Permit Modification (PDF) (2MB, 50pp)

Notice of Permit Modification – TXG330000 - The Environmental Protection Agency (EPA), Region 6, plans to modify the National Pollutant Discharge Elimination System (NPDES) general permit for the Coastal Waters of Texas (No. TXG330000) for discharges from existing and new dischargers and New Sources in the Coastal Subcategory of the Oil and Gas Extraction Point Source Category as authorized by section 402 of the Clean Water Act, 33 U.S.C. 1342. The proposed modification would restore eligibility for certain inland dischargers found in the pervious version of the permit and add freshwater toxicity tests for discharges to fresh waters. A Federal Register notice in early December 2013, will announce availability of the draft permit and supporting documents for public review and provide both the dates of the public comment period and instructions on how to submit comments.

For more information, please contact Evelyn Rosborough, U. S. Environmental Protection Agency, at (214) 665-7515 or rosborough.evelyn@epa.gov.
