Construction General Permit

Highlights of Permit Reissuance of Construction General Permit (2016 CGP) - NEW

On December 29, 2015 DEC reissued the Construction General Permit for Storm Water Discharges for Large and Small Construction Activities (2016 CGP, AKR100000).

The 2016 CGP will become effective on February 1, 2016.

Existing dischargers of the 2011 CGP should submit a new Notice of Intent (NOI, eNOI Reissuance) or Notice of Termination (NOT) within 90 days of the effective date of the 2016 CGP (i.e., no later than April 30, 2016).

In OASys (Online Application System, select the "Storm Water Construction General Permit eNOI Reissuance - (CGPNOIREI)". - NEW

To continue coverage, a permittee must:

  • Continue to comply with the terms and conditions of the 2011 CGP until the permittee has been granted authoization under the 2016 CGP or submits a NOT;
  • Update the existing Storm Water Pollution Prevention Plan (SWPPP) as necessary to comply with the requirements of Parts 3.0, 4.0, and 5.0 of the 2016 CGP; and
  • Submit a complete and accurate NOI within 90 days of the effective date of the 2016 CGP (i.e., no later than April 30, 2016).
  • If a permittee is eligible to submit a NOT (e.g., construction is finished and final stabilization has been achieved) before the 90th day, a new NOI is not required to be submitted provided a NOT is submitted within 90 calendar days after the effective date of the 2016 CGP permit.

The 2016 CGP authorizes storm water discharges from large and small construction-related activities that result in a total land disturbance of equal to or greater than one acre and where those discharges enter waters of the U.S. (directly or through a storm water conveyance system) or a municipal separate storm sewer system (MS4) leading to waters of the U.S. subject to the conditions set forth in the permit. The permit also authorizes storm water discharges from certain construction support activities and some non-storm water discharges commonly associated with construction sites.

The goal of the 2016 CGP is to minimize erosion and reduce or eliminate the discharge of pollutants, such as sediment carried in storm water runoff from construction sites through implementation of appropriate control measures. Polluted storm water runoff can adversely affect fish, animals, plants, and humans. In order to ensure protection of water quality and human health, the permit describes control measures that must be used to manage storm water runoff during construction activities. The 2016 CGP will replace the 2011 CGP that became effective July 1, 2011 and will expire on January 31, 2016.

What Are My Responsibilities As a Construction Operator?

If your project disturbs less than one acre and is not part of the planned disturbance of a larger common plan of development or sale, no permit is required. Otherwise, you must develop and follow a Storm Water Pollution Prevention Plan (SWPPP) to manage materials, equipment, and runoff from your construction site. (Note that this is only a partial list of your responsibilities and that you must consult the Construction General Permit for details.)

  • Obtain and read the entire Construction General Permit prior to beginning your project.
  • Develop a SWPPP. Development and implementation of a construction storm water pollution prevention plan is the key condition of the CGP.
  • Submissions to DEC:
    • Submit an original, signed Notice of Intent (NOI). The NOI can be filed by hardcopy or electronically.
    • 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 $490 (See 18 AAC 72.956 Table E (11)). For those who submit an eNOI there is a step during the eNOI process where payment is required.
    • Some projects are required to submit their SWPPP to DEC or the local governments of Anchorage, Fairbanks, North Pole, or Fairbanks North Star Borough for review. (See SWPPP Submittal Requirements).
    • For your convenience, and to expedite the review of your SWPPP, you may also fill out and submit the checklist with your SWPPP. The form is savable and printable in most versions of Adobe Reader.
  • Implement the storm water controls described in your SWPPP.
  • Receive a confirmation letter and project tracking number from DEC, assigning a unique permit number to your site.
  • Conduct and document inspections of the disturbed areas on site (a)at least every 14 days and within 24 hours of a storm event, or (b) at least every seven days.
  • Maintain erosion and sediment controls whenever necessary, so they operate effectively.
  • Keep a copy of the permit and all associated records on site during the entire construction phase. Use the permit available in the "Of Interest" box on the right.
  • Revise your SWPPP whenever necessary to protect water quality, or to reflect current conditions on site.
  • After construction is completed, submit a Notice of Termination (NOT) to DEC
  • Retain all records for a period of at least three (3) years from the date that the site is permanently stabilized.
  • If you have questions, see the CGP FAQ's in the "Of Interest" box on the right that answers most of the commonly asked questions about the 2011 ACGP. EPA has also developed a set of FAQs about the CGP.
