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.

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.

Generally every one to five years, depending on facility size and other factors.
