The EPA requires National Pollutant Discharge Elimination System (NPDES) permits for certain industrial facilities. In Colorado these permits are issued through the Colorado Department of Public Health and Environment (CDPHE) and regulate stormwater discharges from industrial facilities.

You may need a COR900000 industrial permit with CDPHE if your facility has a SIC code that falls under Sectors A-F, I, K-Z or AA-CC. Please reference Appendix A of the Industrial Facilities Program to identify your assigned industrial Sector based on your SIC code.

If the industrial activities are not exposed to rainfall and stormwater runoff, you may be exempt from needing a permit. Although, you will still need a “No Exposure Certification” through CDPHE. Visit the CDPHE website for more information.

Refer to the Design, Permitting and References section of this website for construction requirements.
