  5. Petroleum Storage Tank Bureau 20.5.6 NMAC Part 6 - Release Detection Presented by Joe Godwin Stakeholders, 7/31/02

  6. Petroleum Storage Tank Bureau Section 600 - Deadlines • No changes for underground storage tank systems. • Existing USTs must have met requirements by 1998 Deadline • New USTs must meet requirements upon installation.

  7. Petroleum Storage Tank Bureau AST Systems Deadlines • Installed on or before June 30, 1991 or where date of installation is unknown shall be inspected and tested by one year from effective date of regulations. The testing will be to ascertain if the tank and piping are structurally sound and if a release is occurring. • If a release is suspected from the results of the tank testing the owner and operator will comply with 20.5.7 NMAC

  8. Petroleum Storage Tank Bureau AST Systems Deadlines • Owners and Operators will meet release detection requirements by July 1, 2004. • Regardless of age any aboveground system that is completely aboveground and can be visibly inspected does not have to be inspected and tested as required by D.1. • Owners and Operators will close any system by July 1, 2004 if they cannot apply a method of release detection that complies with Part 6.

  9. Petroleum Storage Tank Bureau Section 601 - Petroleum Tanks • All petroleum storage tank systems will be monitored monthly for releases by applicable method in 603. • No significant changes for UST systems from previous regulations. • AST systems can perform monthly inventory control in conjunction with testing in accordance with either API 653 or STI SP001-00.

  10. Petroleum Storage Tank Bureau Petroleum Piping • Requirements apply to all petroleum piping. • All piping that conveys regulated substances by pressure will be tightness tested annually unless the entire piping run is aboveground and can be visually inspected. • All pressurized piping will be equipped with an automatic line leak detector.

  11. Petroleum Storage Tank Bureau Petroleum Piping • All pressurized and suction double-walled piping whether aboveground or underground shall have a method of release detection that monitors the interstice of the piping. • No release detection on suction piping if it meets all of the standards listed in 601.B.2.

  12. Petroleum Storage Tank Bureau 20.5.6 NMAC Part 6 - Release Detection

  13. Petroleum Storage Tank Bureau Section 603 – METHODS OF RELEASE DETECTION FOR TANKS Presented by John Cochran Stakeholders, 7/31/02

  14. Petroleum Storage Tank Bureau There are three types of leak detection methods: • Internal • External • Interstitial

  15. Petroleum Storage Tank Bureau Leak Detection Methods: • Internal – monitoring the volume of liquid in the tank to try to detect a loss • Inventory control and tank tightness testing • Manual tank gauging • Automatic tank gauging • Statistical inventory reconciliation (SIR)

  16. Petroleum Storage Tank Bureau Leak Detection Methods: • 2. External – monitoring the environment outside the tank to detect evidence of a leak • Groundwater monitoring (UST only) • Vapor monitoring (UST only) • Visual inspection (ASTs only)

  17. Petroleum Storage Tank Bureau Leak Detection Methods: • 3. Interstitial – monitoring the space between the primary and secondary walls of a secondarily contained tank • Double-wall tanks • Secondary containment with interstitial monitor

  18. Petroleum Storage Tank Bureau Release Detection Requirements for Underground Storage Tanks have not changed!

  19. Petroleum Storage Tank Bureau RELEASE DETECTION FOR ABOVEGROUND STORAGE TANKS (ASTs)

  20. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • Inventory Control and Tank Tightness Testing • Automatic Tank Gauge • Interstitial Monitoring • Visual Inspection

  21. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • Inventory Control and Tank Tightness Testing • Tank tightness tests at 0.2 gallons-per-hour (gph) must be performed 10 years after installation and every 10 years thereafter

  22. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • 2. Automatic Tank Gauge • Must be able to detect a 0.2 gph leak from any portion of the tank that routinely contains a regulated substance

  23. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • 3. Interstitial Monitoring • Double wall tanks • Testing method complies with the requirements of the current edition of an industry code or standard approved in advance by the department

  24. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • 3. Interstitial Monitoring • ASTs inside secondary containment • tanks manufactured or upgraded to contain a double-walled bottom which can be remotely monitored; or • tanks installed inside the secondary containment with an impervious barrier beneath the tanks and the interstice can be remotely monitored;

  25. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • 3. Interstitial Monitoring • ASTs inside secondary containment • Groundwater, soil moisture, or rainfall will not render the testing or sampling method inoperative • Owners and operators conduct an annual test of the operation of the interstitial sensor in accordance with the manufacturer’s requirements

  26. Petroleum Storage Tank Bureau Release Detection Methods for ASTs • 4. Visual Inspection • May be used if all portions of the tank, including the tank bottom, are visible and readily accessible. • The tank(s) must be inspected monthly and the owner and operator must keep a log that includes the date, time, initials of the inspector, comments on the condition of each tank, and the results of each inspection

  27. Petroleum Storage Tank Bureau Section 604 - METHODS OF RELEASE DETECTION FOR PIPING: Presented by Joseph Romero Stakeholders, 7/31/02

  28. Petroleum Storage Tank Bureau Release Detection Methods for Piping • Automatic Line leak Detectors • Line Tightness Testing • Interstitial Monitoring • Visual Inspection

  29. Petroleum Storage Tank Bureau Release Detection Methods for Piping • 1. Automatic Line Leak Detectors • All pressurized piping will be equipped with an automatic line leak detector • 2. Line Tightness Test • Pressurized piping shall be tightness tested annually unless the entire piping run is aboveground and can be visually inspected

  30. Petroleum Storage Tank Bureau Release Detection Methods for Piping • 3. Interstitial monitoring • Owners and operators may use interstitial monitoring if they ensure that interstitial monitoring for double-wall piping, under pressure and under suction, complies with the current edition of an industry code or standard approved in advance in writing by the department, or with piping manufacturer’s requirements

  31. Petroleum Storage Tank Bureau Release Detection Methods for Piping • 4. Visual inspection • For above ground tanks, visual inspection may used for piping if all portions of the piping are visible and readily accessible, and are inspected monthly

  32. Petroleum Storage Tank Bureau Section 605 - ALTERNATIVE METHODS If owners and operators want to install another method of release detection equipment for tank or piping required in Section 601 through 604 of 20.5.6 NMAC in accordance with the current edition of an industry code or standard, owners and operators shall apply in writing to the department, shall provide supporting documentation, and shall not begin the installation unless and until the department approves the request in writing.

  33. Petroleum Storage Tank Bureau Section 606 - Record Keeping Presented by Patrick Moore Stakeholders, 7/31/02

  34. Petroleum Storage Tank Bureau Record Keeping Requirements • This Section Pertains To All Storage Tank System Owners and Operators ( AST and UST ) • If the owner and operator of a storage tank are separate persons, only one person is required to maintain the records required by this section; however, both parties are liable in the event of noncompliance

  35. Petroleum Storage Tank Bureau Record Keeping Requirements • All written performance claims pertaining to any release detection system – 5 years from date of installation • Results of sampling, testing, or monitoring – 1 year • Tank tightness testing – Until the next test is conducted • Written documentation of all calibration, maintenance, and repair of release detection equipment – 1 year after the servicing work is completed • Any schedules of required calibration and maintenance provided by manufacturer – 5 years from date of installation
