Watershed Regulatory


watershed regulatory picture


   
The Watershed Regulatory Section implements the National Pollutant Discharge Elimination System (NPDES) permitting for the region. The Municipal Permitting Unit develops NPDES permits for discharges from POTWs to surface water and water reclamation requirements (WRRs) and waste discharge requirements (non-Chapter 15 discharges to land, WDRs) for POTWs that also hold NPDES permits.

The Industrial Permitting unit writes or updates permits for non-POTW facilities, such as refineries, power plants, manufacturing, and other industries with discharges to surface waters within the region. Often, certain classes of discharges are identified and, where similar types of discharges occur from similar types of operations, general permits are developed to streamline the permitting process.

The General Permitting unit enrolls these similar categories of discharges under existing general permits. The categories being enrolled include construction dewatering without treatment; construction dewatering with treatment; hydrostatic test water; non-process wastewater; petroleum fuel cleanup; and, cleanup of volatile organic compounds.
