Permit background
To protect Colorado waters from pollutants in stormwater runoff, the division requires operators of certain industrial facilities to obtain permit coverage for actual or potential stormwater discharges. The COR900000 permit requires facilities to:
- Implement a stormwater management plan.
- Implement specific stormwater control measures (i.e., best management practices).
- Perform inspections.
- Monitor pollutants in their discharge.
- Evaluate the effectiveness of the stormwater management plan and control measures.
No exposure exclusion from CDPS stormwater permitting
"No Exposure" is an alternative to obtaining coverage under the COR900000 permit. In this context, "No Exposure" means that storm-resistant sheltering is in place to prevent exposure to rain, snow, snowmelt, or runoff. To be eligible for this exclusion, you must apply for and obtain division approval by issuing a certification. Part G of the application contains a self-certifying checklist for you to assess whether your facility meets conditions of "No Exposure."
