Industries Required To Obtain Stormwater Permits
Permit Assistant - What type of permit(s) do we need? This tool is designed to help users determine what type of environmental permits they need and provide the forms to apply for these permits. This easy-to-use tool will ask you a few simple questions to determine your needs. Let's get started!
General Stormwater 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.
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 Stormwater 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.
- No Exposure Exemptions are now possible under
Phase II. Missouri uses the EPA No Exposure form. Industries
should file this form with their regional DNR office.
- EPA’s No Exposure Exemption Form
- Missouri instructions for completing and submitting the No Exposure Exemption Application Form
- DNR 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 Stormwater regulations are in effect. Provisions within Intermodal Surface Transportation 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 Stormwater 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 Transportation Efficiency Act-exempted municipally operated industrial activities were required to obtain permit coverage.
