eNOI Overview

EPA has updated and improved the Electronic Notice of Intent (eNOI) for industrial facilities that need to apply for coverage under EPA's Multi-Sector General Permit (MSGP). The eNOI system is a free online service. Use this system only if your construction site or industrial facility is located in a state in which EPA is the permitting authority. Please click the eNOI logo to start to file an electronic Notice of Intent.

As of October 31, 2009, the Alaska Department of Environmental Conservation is now the stormwater permitting authority in Alaska Exit EPA Site. Please go to their website to find out how to submit your Notice of Intent.

Gaining Access to the eNOI System and Training

Industrial facilities can apply for coverage under EPA's MSGP via the eNOI system. First time users must register to gain access to use the eNOI system. See Registering for eNOI (PDF) (2 pp, 211K) to learn how to begin this process. Federal regulations require the certification of Notice of Intent forms by a responsible corporate officer or a principle executive or ranking elected official (for government organizations).

If you are a Certifying Official and do not have an eNOI account, you must register through EPA's CDX interface. Go to eNOI Certifying Officials (PDF) (2 pp, 289K) for more information on certifying officials.

To learn more about the eNOI system, including how to register and use the system, click here to view the revised eNOI Overview in PowerPoint format (PPT) (52 pp, 2MB) or Overview in PDF format (PDF) (52 pp, 1.24MB) .
