View 2008 CGP and 2008 MSGP Stormwater NOIs

You can use the search features below to view stormwater notices of intent (NOIs) for construction projects under EPA's 2008 Construction General Permit (CGP), for Low Erosivity Waivers (LEWs) submitted prior to September 10, 2013, or for industrial facilities under EPA's 2008 Multi-Sector General Permit (MSGP) or industrial facilities that are covered under the No Exposure certification.

To view NOIs submitted under EPA's 2012 CGP or LEWs submitted on or after September 10, 2013, go to the Construction General Permit Public Search page.

Using the search features below, you can find information in a number of different ways on construction projects or industrial facilities that have applied for permit coverage. You can search for a particular company by entering information about the owner/operator. You can search for a specific construction site or industrial facility by entering information about the site/facility location, such as name, city, county, state, or zip code. You can also search by status, region, and date. See below for descriptions of the four status types.

There are four major status types:

Waiting - A complete NOI has been received. EPA's Construction General Permit (CGP) and Multi-Sector General Permit (MSGP) both require a waiting period from the time an NOI is posted on EPA's website until coverage under the permit begins. The waiting periods are as follows:

  • Construction General Permit - There is a 7-day waiting period for the Construction General Permit.
  • Multi-Sector General Permit - The waiting period for the MSGP depends on your discharger category and whether or not your stormwater pollution prevention plan (SWPPP) is posted on the Internet. The waiting periods are as follows:
    • Existing dischargers covered under the 2000 MSGP - 30 days after EPA posts the NOI on this webpage.
    • New dischargers or sources that started discharging between October 30, 2005 and January 5, 2009 - 30 days after EPA posts the NOI on this webpage.
    • New dischargers or new sources that started discharging after January 5, 2009 -
        If the SWPPP is posted on the Internet and the Internet address (i.e., URL) to your SWPPP is provided on the NOI form, then 30 days after EPA posts the NOI on this webpage; or
        If the SWPPP is not posted on the Internet, then 60 days after EPA posts the NOI on this webpage.

During the waiting period NOIs can be reviewed by EPA, the U.S. Fish and Wildlife Service, and the National Marine Fisheries Service.

Active - A complete NOI has been received. The waiting period has been completed and no additional issues have been identified. Coverage under the EPA permit began on the date indicated.

On Hold - A complete NOI has been received, however, it has been placed on hold by EPA. This project or facility is ineligible for coverage under the EPA permit until identified issues are resolved.

Terminated - A Notice of Termination (NOT) has been submitted for this project. This project is no longer covered by the EPA permit.
