What if everything we do is indoors?
You may submit a No Exposure Certification if all of your industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and/or runoff. Read Appendix K of the MSGP: No Exposure Certification (PDF) (6 pp, 245K) to determine if you're eligible for exclusion from stormwater permitting.

If you're eligible, file your No Exposure Certification online.

How do I get a permit?

The 2015 permit is available for all operators except those within the Spokane Reservation and non-tribal lands in Idaho (those operators see box below).

  1. Read the Multi-Sector General Permit (PDF) (369 pp, 3.3MB). A Technical Fact Sheet (PDF) (78 pp, 791K) is also available.
  2. Prepare a Stormwater Pollution Prevention Plan (see guidance below)
  3. Complete the endangered species determination
  4. Complete the historic properties determination
  5. Submit your Notice of Intent (NOI) online. Electronic submittal is required in most circumstances, but you can review the information needed in Appendix G: NOI for Industrial Stormwater Discharges (NPDES Form 3510-6) (PDF) (8 pp, 269K).
  6. Wait for confirmation from EPA that your facility is covered (typically within 30 days).
Other Guidance

Operators within the Spokane Reservation and non-tribal lands in Idaho:

We expect that the Spokane Tribe and the State of Idaho will certify the permit soon, and this page will be updated when that occurs. In the interim:

A. If you have coverage under the 2008 permit, your permit continues to be administratively extended. EPA will notify you when the 2015 permit is available for you to sign up. Feel free to update your contact information with Margaret McCauley (mccauley.margaret@epa.gov) at 206-553-1773 to make sure a current contact is on the notification list.

B. If you are a new owner of an existing facility or a new facility, determine if you:

    1. meet the 2008 MSGP eligibility criteria; if so,
    2. file the Notice of Intent for coverage (PDF) (7 pp, 714K) with EPA Region 10: Attention: MSGP Coordinator, U.S. EPA Region 10, OWW-191, 1200 Sixth Avenue, Suite 900, Seattle, WA 98101; and
    3. comply with all the requirements of the 2008 MSGP.

More information is available in our memorandum No Action Assurance for the NPDES Stormwater Multi-Sector General Permit for Industrial Activities (PDF) (5 pp, 490K).
