The Final National Pollutant Discharge Elimination System (NPDES) General Permit for Remediation Activity Discharges – the Remediation General Permit (RGP) in Massachusetts (MAG910000) and New Hampshire (NHG910000) was signed on March 9, 2017. The RGP is effective 30 days after the date of signature, on April 8, 2017. The final RGP replaces the RGP that expired on September 9, 2015. The 120-day period for seeking judicial review will begin at 1:00 pm Eastern Standard Time on March 23, 2017, in accordance with 40 C.F.R. Part 23. Under section 509(b) of the Clean Water Act, judicial review of this general permit can be requested by filing a petition for review in a United States Court of Appeals by July 21, 2017.

The RGP is available for sites located in Massachusetts and New Hampshire which discharge 1.0 million gallons per day or less as a result of remediation activities from eight general categories: 1) Petroleum-related site remediation; 2) Non-petroleum-related site remediation; 3) Contaminated/formerly contaminated site dewatering; 4) Pipeline and tank dewatering; 5) Aquifer pump testing; 6) Well development/rehabilitation; 7) Collection structure dewatering/remediation; and 8) Dredge-related dewatering.

Operators seeking authorization to discharge must submit a complete and accurate Notice of Intent (NOI) in accordance with Appendix IV – Part 1 as follows:

  • Operators of existing discharges must submit a NOI no later than ninety (90) days after the effective date of this general permit.
  • Operators of emergency discharges must submit a NOI no later than fourteen (14) days after the discharges commence.
  • Operators of new discharges must submit a NOI at least seven (7) days prior to the commencement of discharges.

An operator will be authorized to discharge under the RGP upon the effective date indicated in the authorization to discharge provided by EPA in writing, unless provisional coverage for an emergency discharge applies.

In accordance with 40 C.F.R. Part 122.63, EPA is providing notice that the minor modifications listed below have been processed for this general permit.

Correct typographical errors per 40 C.F.R. Part 122.63(a)

March 28, 2017: Appendix I
In the instructions in Section II, Step 3 (FWS Criterion C), found on page 5 of 10, the term "both" was corrected to "either" and the term "either" was corrected to "both". In the instructions in Section II, Step 4, found on page 6 of 10, the documentation for FWS Criterion C was corrected to reflect the correction made in Section II, Step 3. The cross-references to the criteria in Sections II and III, found on page 3 of 10, were corrected for numbering.

April 19, 2017: General Permit
In footnote 7 to Table 2, found on page 12 of 50, the units "µg/L" were corrected to the units "mg/L" for the minimum level requirement for the parameter ammonia. This correction was not made in Appendix VII or Attachment A because the units for the minimum level requirement for the parameter ammonia, mg/L, are correct in both Appendix VII and Attachment A.
