Underground Storage Tanks

You will have to keep records that can be provided to an inspector during an on-site visit that prove your facility meets certain requirements. These records must be kept long enough to show your facility's recent compliance status in the major areas listed below. You should check with your state or local regulatory authority about the particular recordkeeping requirements in your area.

• You will have to keep records of leak detection performance and maintenance:
  • The last year's monitoring results, and the most recent tightness test.
  • Copies of performance claims provided by leak detection manufacturers.
  • Records of recent maintenance, repair, and calibration of on-site leak detection equipment.
• You will have to keep records showing the required inspections and tests of your corrosion protection system.
  
• You must keep records showing that a repaired or upgraded UST system was properly repaired or upgraded.
  
• For at least 3 years after closing an UST, you must keep records of the site assessment results required for permanent closure. (These results show what impact your UST has had on the surrounding area.)
  
• You must keep records that document your financial responsibility, as explained in EPA's booklet, Dollars And Sense.
