Industries Required To Obtain Storm Water Permits

Phase II Highlights for Industrial Permits

There are still 11 categories of industrial classifications covering 30 sectors of industrial activity that are required to obtain storm water discharge permits. However, the North American Industry Classification System has replaced the U.S. Standard Industrial Classification System. Both systems classify establishments by their primary type
of activity.
- U.S. Environmental Protection Agency (EPA) Industrial Classification
  Fact Sheet
No Exposure Exemptions are now possible under Phase II. Missouri uses the EPA No Exposure form. Industries should file this form with their regional MoDNR office.

- Missouri instructions for completing and submitting the No Exposure Exemption Application Form PDF
- MoDNR Regional Offices
- Additional information regarding Conditional No Exposure Exclusion, including fact sheet and exclusion guidance manual.
Intermodal Surface Transportation Efficiency Act Exemptions lifted under Phase II. Municipally owned and operated industrial sources that were exempted by the Intermodal Surface Transportation Efficiency Act of 1991 are no longer exempt from permitting requirements now that Phase II storm water regulations are in effect. Provisions within Intermodal Surface Transporation Efficiency Act temporarily delayed the deadline for Phase I sources (industrial activities with the exception of power plants, airports, and uncontrolled sanitary landfills) operated by municipalities with populations of less than 100,000 people to obtain an NPDES storm water discharge permit. Congress delayed the permitting deadline for these facilities to allow small municipalities additional time to comply with NPDES requirements. The Phase II Final Rule ended this temporary exemption from permitting. Since March 10, 2003, all Intermodal Surface Transporation Efficiency Act-exempted municipally operated industrial activities were required to obtain permit coverage.
General Permits for Missouri’s Industrial Activities Unless a site-specific permit is required, the regulated industry will be required to meet the conditions of these general permits.
