1. Do I need a stormwater permit? How do I apply?
   As of March 10, 2003 in order to discharge stormwater from a construction site, all construction projects that disturb 1 acre or more of land must have either:
   • an individual stormwater permit, or
   • coverage under one of Missouri's general permits.
   Disturbance includes, but is not limited to soil disturbance, clearing, grading, and excavation. Operators of sites disturbing less than one acre are also required to obtain a permit if their activity is part of a "larger common plan of development or sale" with a planned disturbance of one acre or greater.

   To apply for an individual permit or for coverage under a statewide general permit you must file an application with the Department of Natural Resources, Division of Environmental Quality prior to commencement of your construction activities.

   In addition to these statewide rules, you may be required to meet additional local stormwater and erosion control regulations. Check with your city or county government to determine if additional local rules apply to your construction project.

2. Where can I find permit application forms and instructions?
   
   • Form G - Applicatin for Storm Water Permit (This form must include Form E)
   • Form E - Application for General Permit
   • Form H - Request for Termination of a General Permit
   • Form A - Application for Construction or Operating Permit
   • Form O - Applicatoin for Land Disturbance Permit (< 5 ACRES)

3. Where can I find a copy of the General Permit?
   • MO-R101000 for existing sites or MO-R10A000 for new sites
     
     • Permit effective date: 02/08/2007; Permit expiration date: 02/07/2012
     • Stormwater Pollution Prevention Plan Summary. Note: Make sure you download and read the permit. Included below is only a brief summary of the required SWPPP contents and this summary is not intended to be a guide for creation of an SWPPP.
       • Deadlines for creation and implementation of the SWPPP:

         Developed before a permit can be issued and made available.

       • Summary of Plan Contents:

         1. Site Description: In order to identify the site, the SWPPP shall include the facility and outfall information provided in the Application Form. The SWPPP shall have sufficient information to be of practical use to contractors and site construction workers to guide the installation and maintenance of BMPs.

         2. Drainage areas. Adherence to guidelines described in the permit.

         3. Description of Best Management Practices: The SWPPP shall include a description of the BMPs that will be used at the site.

         4. Disturbed Areas: Slopes for disturbed areas must be defined in the SWPPP. Where soil disturbing activities cease in an area for more than 14 days, the disturbed areas shall be protected from erosion by stabilizing the area with mulch or other similarly effective erosion control BMPs.

         5. Installation: The permittee shall ensure the BMPs are properly installed at the locations and relative times specified in the SWPPP.

         6. Temporary and Permanent Non-Structural BMPs: The SWPPP shall require existing vegetation to be preserved where practical. The time period for disturbed areas to be without vegetative cover is to be minimized to the extent practical.

         7. Temporary and Permanent Structural BMPs: Examples of structural BMPs that the permittee should consider specifying in the SWPPP include: diverting flows from undisturbed areas away from disturbed areas, silt (filter fabric or straw bale) fences, earthen diversion dikes, drainage swales, sediment traps, rock check dams.

         8. Sedimentation Basins: The SWPPP shall require a sedimentation basin for each drainage area with 10 or more acres disturbed at one time.

         9. Additional Site Management BMPs, such as portable toilets, solid and hazardous waste management should be addressed.

         10. Permanent Storm Water Management: The SWPPP shall include a description of the measures that will be installed during land disturbance to control pollutants in storm water discharges that will occur after land disturbance activity has been completed.
