Release Detection Testing

Beginning on October 13, 2018 owners and operators must test electronic and mechanical components of their release detection equipment for proper operation at least annually using one of the following options:

  • Manufacturer’s instructions
  • A code of practice developed by a nationally recognized association or independent testing laboratory
  • Requirements developed by the implementing agency


When testing, check the following:

  1. Automatic tank gauge and other controllers
    • Test the alarm
    • Verify the system configuration
    • Test the battery backup
  2. Probes and sensors
    • Inspect for residual buildup
    • Ensure any floats move freely
    • Ensure any shafts are not damaged
    • Ensure the cables are free of kinks and breaks
    • Test the alarm oper-ability and communication with the controller
  3. Automatic line leak detector
    • Ensure the device activates (alarms, restricts flow, or shuts off flow) within an hour when simulating a release equivalent to 3 gallons per hour at 10 pounds per square inch
  4. Vacuum pumps and pressure gauges
    • Ensure there is proper communication with sensors and the controller
  5. Hand-held electronic sampling equipment associated with groundwater and vapor monitoring
    • Ensure the device operates properly

Owners and operators must maintain records of release detection equipment testing for at least three years. The record must include each component tested, whether each component passed the test or needed to have action taken, and any action taken to correct an issue.
