The Water Enforcement Branch is responsible for reviewing compliance by Industrial Facilities (including construction sites) with the storm water regulations and the NPDES permitting program.

- The eNOI database is only for NPDES applications where EPA is the NPDES permitting authority.
- If you have questions about this database, you may contact our NOI Processing Center contractor, CTGI, at (866)352-7755.

Construction General Permit
- General Permit for Storm Water Discharge from Construction Activity.
- Office of Water Resource Center (202)566-1729 .
- Industrial activities (except construction) that do not have exposure to storm water, are exempted from the NPDES permitting if they:
- correctly complete a "No Exposure Certification" (pdf), and
- submit it to the NPDES permitting authority.
- Category 11 facilities [40 CFR 122.26(b)(14)(xi)] may remain exempted from the NPDES permitting authority. However, they are now required to submit the "No Exposure Certification" (PDF) form to the NPDES permitting authority.
- Failure to either obtain an NPDES storm water permit or else submit a "No Exposure Certification" for category 11 facilities is a violation of the Clean Water Act effective February 7, 2000.
- Please read the "No Exposure Certification" instructions very carefully to determine whether your facility is eligible. Additionally, you may want to utilize the guidance for No Exposure Certification (PDF) issued by the Office of Water in July 2000. An incorrect interpretation may subject facilities to civil penalties.
Multi-Sector General Permit
- The Final Draft of the 2008 MSGP (PDF) (247 pp, 2.09MB) was announced on September 29, 2008, in the Federal Register.
- This permit replaces the 2000 MSGP (PDF) (136 pp, 1.3MB), which expired on October 30, 2005.
- The 2008 MSGP provides coverage for industrial facilities (PDF) Region 6's New Mexico industrial facilities, and in certain Indian Country lands, as well as at various Federal Facilities in other States (see Appendix C of the 2008 MSGP (PDF) (5 pp, 547K)), where EPA still remains the NPDES permit authority.
- The 2008 MSGP specifies steps that facility operators must take prior to becoming eligible for permit coverage, including submitting a Notice of Intent (NOI), installing stormwater control measures to minimize pollutants in stormwater runoff, and developing a stormwater pollution prevention plan (SWPPP).
- EPA has released a guidance on how to develop a SWPPP that meets the requirements of the 2008 MSGP.
- View the general two-page fact sheet (PDF) (2 pp, 72K) summarizing the final 2008 MSGP.
