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.
  • NC DWR is not currently flowing DMR data to EPAIn late 2014, the U. S. Environmental Protection Agency (EPA) made updates to its computer system that required batch states like North Carolina (states that send data by computer to EPA at one time) to install the latest version of an interface in order to continue sending NPDES data from the state’s data system to EPA’s, ICIS-NPDES.  NC DWR is awaiting the new interface from EPA’s contractor and has not been able to send any NPDES data, including Discharge Monitoring Report (DMR) data, to EPA since late-September 2014.  The absence of the DMR data in ICIS-NPDES has resulted in EPA-generated DMR non-receipt violations for North Carolina’s NPDES wastewater permits.  For major NPDES permits, these violations are also reflected in EPA’s Enforcement and Compliance History Online (ECHO) database as Significant Non-Compliance (SNC) violations.  Once NC DWR obtains the needed plugin from the EPA contractor, Division staff will work diligently to resume data flow to EPA and will upload all DMR data received from NPDES permittees since September 2014 to ICIS-NPDES.  After all data is in ICIS-NPDES, Division staff will work with EPA to remove all invalid DMR non-receipt violations from EPA’s databases, ICIS-NPDES and ECHO.  If you have any questions, please contact Vanessa Manuel at 919-807-6392. 
  • NPDES Standard Conditions (Current) 
  • 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
