NPDES Industrial Storm Water General Permit

Online Application Process

The Department of Environment and Energy (NDEE) has issued the National Pollutant Discharge Elimination System (NPDES) Industrial Stormwater General Permit (ISW-GP) NER920000.

The permit became effective April 1, 2022 and expires March 31, 2027.

The deadline to renew coverage is no later than September 28, 2022. A notice of intent (NOI) must be received by the NDEE at least 30 days prior to facility start-up.

The new permit and fact sheet are attached above. In addition, the documents highlighted below can also be found on this page:
 

  • Those who are uncertain if the industrial storm water program applies to their facility should compare the facility’s Standard Industrial Classification (SIC) to those listed in Appendix D – Facilities and Activities Covered, also see 21-030 Industrial Storm Water Guidance for additional information.
  • Those who are qualified for the No Exposure Certification (NEC) under NER910000 are required to submit a new certification request under NER920000 using the Online Application Process. See Part 1.5 of the Permit and Attachment 2 – No Exposure Certification Guidance and Checklist for more information.
  • Facilities that no longer require coverage or are permanently out of operation need to submit the Notice of Termination (NOT) form.

 

Additional Implementation Measures (AIM)


New to NER920000 are the Additional Implementation Measures (AIM) requirements. All facilities covered under NER920000 with benchmark monitoring requirements are subject to Additional Implementation Measures (AIM) as described in Part 3.2 of the permit.

AIM outlines the corrective actions and steps required for benchmark exceedances. AIM is a three-level response that provides a follow-up process. AIM Levels are sequential and cannot be skipped. The AIM requirements apply on a pollutant parameter-specific, per discharge point basis.

See the 22-004 AIM Guidance Document for additional information.

The EPA has also provided useful tools and information to help determine your AIM level and appropriate corrective actions or best management practices (BMPs) that may be beneficial to meeting benchmarks.
