Multi-Sector General Permit

Highlights of Permit Reissuance (2020 MSGP)

The 2020 MSGP was reissued on February 20, 2020 as AKR060000 and will go into effect April 1, 2020. Existing permittees will have 120 days from April 1, 2020 (to July 29, 2020) to revise their Storm Water Pollution Prevention Plan (SWPPP) and submit the SWPPP with a new Notice of Intent (NOI) application. Existing permittees should have already received invoices for the general permit authorization annual fee. If you file electronically, please check the box in the on-line application that says you paid via invoice.

What Are Your Permit Responsibilities As a Facility Operator?

Operators of industrial facilities requiring an APDES Storm Water Permit are eligible to obtain coverage under the MSGP if their activities are included within one of 29 industrial sectors. See Appendix D of the MSGP for a listing of facilities and activities that are covered. (Note that this is only a partial list of your responsibilities and that you must consult the Multi-Sector General Permit for details.)

  • Determine whether the facility or site discharges to a municipal separate storm sewer system (MS4) or to waters of the United States. If it does not, no permit is required.
  • Determine if the facility's industrial activities are listed among the eleven Categories of Industrial Activities, provided in the federal regulations at 40 CFR 122.26(b)(14) or if the facility's SIC code falls within one of the sector/subsectors identified in Appendix D of the MSGP or use the SIC and NAICS - Sectors Cross-Reference. If its activities are not listed, no permit is required.
  • Determine if the listed facility or site may qualify for the "no exposure" exclusion under the federal regulations at 40 CFR 122.26(g)
  • Develop a storm water pollution prevention plan (SWPPP). Development and implementation of an industrial SWPPP is the key condition of the MSGP.
  • Keep a copy of the permit and all associated records on site during the entire permit period.
  • Submissions to DEC:
    • Submit an original signed Notice of Intent (NOI). The NOI can be filed by hardcopy.
    • With a paper copy of the NOI submit a check payable to the "State of Alaska" for the amount of the General Permit Authorization Fee of $735 (See 18 AAC 72.956 Table D (11)). For those who submit an eNOI, there is a step during the eNOI process where payment is required. This is a fee that has to be paid annually. DEC will bill the facility in subsequent years for the annual fee.
    • Provide a copy of the SWPPP (digital format (PDF) preferred).
    • For your convenience, and to expedite the review of your SWPPP, you may also fill out and submit the checklist provided in the "Of Interest" box to the right – click on "DEC MSGP SWPPP"

Monitoring - Discharge Monitoring Report (DMR)

Permittees are reminded that several sectors require either quarterly benchmark monitoring and/or annual effluent limitation monitoring as detailed in MSGP Permit Part 7.0 (Monitoring) and Part 11 (Sector Specific Requirements). Benchmark monitoring and effluent limit monitoring must be conducted in accordance with MSGP Permit Part 7.1 (Monitoring Procedures) and reported to DEC as required in MSGP Permit Part 9.1 (Required Monitoring Data to DEC).

Permittees must submit DMR data electronically through NetDMR per Phase I of the e-Reporting rule (40 CFR 127) upon the effective date of the Permit. Authorized persons may access permit information by logging into NetDMR Portal.

DMRs submitted in compliance with the e-Reporting Rule are not required to be submitted as described in Appendix A - Standard Conditions unless requested and approved by the Department. Any DMR data required by the Permit that cannot be reported in a NetDMR field shall be included as an attachment to the NetDMR submittal.

DEC has established an e-Reporting Information website that contains general information about this new reporting format. Training materials and webinars for NetDMR can be found at NetDMR website.
