Prepare for the inspection
The division will review these records
Each Colorado Discharge Permit System permit has different record-keeping requirements. The best way to prepare for an inspection is to review the requirements of your facility's permit, but generally, for a CDPS process water discharge, you’ll need to have available the past three years of:
- Permits, including permit certifications.
- Discharge monitoring reports, associated laboratory reports and sampling records, including log sheets and calculations.
- Flow measurement historical flow records and calibration records.
- Operator certification records.
- Stormwater Management Plan (for stormwater inspections).
- We may request other records.
We may conduct a field review
- Depending on the location and inspection goals, we may inspect the integrity of the facilities, for example, compliance points for sampling and flow measurement, and treatment unit processes.
- We may inspect other items.
Inspection frequency
- Generally, it is every one to five years, depending on facility size and other factors.
- We have the authority to inspect CDPS-permitted facilities without advance notice.
After the inspection
- We’ll document the CDPS inspection findings in a letter sent out approximately 45 days after the inspection.
- We request the permittee respond in writing to violations 30 days after the inspection letter date with a plan to address any violations.
