Compliance Inspections

What Owners Need To Know About Compliance Inspections:

  • Each facility must be inspected every three years.
  • Inspections must be conducted by a Licensed Inspector
  • Compliance inspections MUST BE conducted at least 90 days before the current Operating Permit expires.
    • This allows the time to correct any violations discovered during the inspection. 
    • A new Operating Permit is issued for a UST system each inspection cycle.
  • UST owners must schedule and pay for the compliance inspection.
    • Please note that the cost of UST inspections is not set forth in law or rule; your cost to obtain an inspection may vary due to location, inspector, time of year, or other factors.  
  • The owner and inspector must sign or initial all pages of the inspection report. 
  • Compliance inspections must be received by DEQ within 15 days of the inspection. 
  • DEQ reviews each compliance inspection and will determine compliance. If your facility is not in compliance, you and your inspector will receive a Corrective Action Plan from the department which will outline the violations and corrective action timeframes established for your facility. 

Make your Compliance Inspection easier by:

  • Keeping all paperwork, files and records relating to your UST system accessible.
  • Having a staff person who has knowledge of your UST systems on site during the inspection.
  • Making sure all manways, sumps, boxes and equipment are easily accessible.
  • Asking questions, taking notes and contacting DEQ for help.
