Prepare for the inspection
We’ll 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 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.
