NPDES Wastewater
Permitting & Compliance Program

The National Pollutant Discharge Elimination System (NPDES) program was established by the federal government to control point-source discharges of wastewater. The North Carolina Division of Water Resources is responsible for administering North Carolina's NPDES Permitting and Compliance Program. We aim to protect, maintain and enhance North Carolina's waters by fostering compliance with North Carolina's environmental statutes, regulations and permits.

The following lists are provided for informational purposes only. They are updated on a monthly to quarterly basis and should only be considered accurate as of their day of posting.
  • e-DMR: What is e-DMR?
  • General Permit NCG590000 became effective on August 1, 2014This is a five year general NPDES permit that applies to Greensand and Conventional type Water Treatment Plants. Facilities granted coverage under this permit are expected to have reduced permitting costs and will be able to obtain permit renewals more efficiently and quickly. Please proceed to the following NPDES Wastewater - General Permits link to review and apply for the NCG590000 general permit.
  • NC Model Mercury Minimization PlanAs a part of the Post TMDL Permitting strategy passed by the Environmental Management Commission in November 2012 some Major municipal facilities with detectable mercury in their effluent will be required to develop Mercury Minimization Plans within 180 days of their NPDES permit renewal.  The plans do not need to be submitted to the state but are subject to review during inspection.  To view a model plan, click here.
  • Pesticide Discharge Management Plan: Effective January 1, 2012, for a copy, click here.
  • EPA Watch List - NC Facilities (May 2014): The Watch List identifies major NPDES permitted wastewater facilities that have exceeded various U.S. Environmental Protection Agency water quality compliance criteria. It promotes communication between EPA and the states on enforcement issues and helps federal, state and local agencies to track Clean Water Act compliance and enforcement activities.  Facilities may appear on the watch list because of violations that identify significant noncompliance. Some of the facilities are on the list because they are under existing orders, are actively participating in negotiations with regulators or are the subject of an investigation. Some facilities may be on the list due to database errors – these are usually identified and addressed in dialogue between the state and EPA. The list is updated quarterly.
  • NPDES Standard Conditions (November 2011) 
  • Dissolved Metal to Total Metal Limit Calculators: ***REVISED***  Includes median HUC hardness values, User Guide and Calculators to assist permittees in understanding how the proposed Surface Water Standards (dissolved metals) will impact NPDES Permit Limits.
  • Stormwater Dissolved Metals Implementation & Estimated Benchmark Revisions
