Inspection Frequency:  The inspection frequency for CDPS permits is generally every one to five years depending on facility size and other factors.  However, the Water Quality Control Division (division) has the authority to conduct inspection to CDPS permitted facilities without advance notice.

Preparation:  Each CDPS permit has different record keeping requirements.  The best way to prepare for an inspection is to review the requirement of the facility's permit.  Generally, the following documentation must be available for the past three (3) years for review during a facility inspection (may include but not limited to):

  • Permit including permit certification (i.e., for General Permits)
  • Discharge monitoring reports, association laboratory reports, and sampling records including log sheets and calculations (e.g. averages)
  • Flow measurement historical flow records and calibration records
  • Operator certification records
  • Laboratory records, procedures, and practices (for Permittees that perform on-site analysis)
  • Stormwater Management Plan (SWMP) - For Stormwater inspections

Field Review:  Depending on the location and inspection goals, a Field Review may include, but not be limited to, observation of the integrity of facilities (e.g., compliance points for sampling and flow measurement, treatment unit processes).

Response to the CDPS Inspection Letter:  The Division will document the CDPS inspection findings in a letter sent out approximately 45 days after the inspection.  The Division requests that the Permittee respond in writing to violations 30 days after the inspection letter date with a plan to address any violations.
