Title 38, §564: Regulation of underground oil storage facilities used to store motor fuels or used in the marketing and distribution of oil
§564. Regulation of underground oil storage facilities used to store motor fuels or used in the marketing and distribution of oil
The department shall adopt rules necessary to minimize, to the extent practicable, the potential for discharges of oil from underground oil storage facilities and tanks used to store motor fuel or used in the marketing and distribution of oil to others. These rules must ensure that requirements and standards governing facilities under this section assure that the State's program meets requirements under the United States Resource Conservation and Recovery Act of 1976, Subtitle I, as amended. These rules are limited to the following requirements. [PL 2017, c. 333, §3 (AMD).]
1. Design and installation standards for new and replacement facilities. Design and installation standards for new and replacement facilities are as follows.
A. All new and replacement tanks, piping and below ground ancillary equipment must be constructed of fiberglass, cathodically protected steel or other equally noncorrosive material approved by the department. All new and replacement tanks must include secondary containment, continuous monitoring of the interstitial spaces for all piping and below ground ancillary equipment except for suction piping systems installed in accordance with subsection 1-A. Both tanks and piping must be constructed of materials compatible with the product to be stored. Anchoring is required of tanks when located in a site where the ground water is expected to reach the bottom of the tank or in a 100-year flood plain. [PL 1991, c. 494, §3 (AMD).]
B. All new and replacement facilities must be installed in accordance with the equipment manufacturer's specifications and nationally accepted standards and by an underground oil storage tank installer who has been properly certified pursuant to Title 32, chapter 104-A, and must be registered with the commissioner prior to installation pursuant to section 563. Underground gasoline storage tanks may be removed by an underground gasoline storage tank remover who has been properly certified pursuant to Title 32, chapter 104-A. New and replacement impressed current cathodic protection systems must be designed by a corrosion expert. [PL 1991, c. 66, Pt. B, §3 (RPR).]
C. [PL 1989, c. 865, §10 (RP).]

1-A. Leak detection standards and procedures for existing facilities. Facility owners shall implement one of the leak detection methods listed in this subsection or properly abandon a facility in accordance with section 566-A. The leak detection system must be capable of detecting a leak within 30 days with a probability of detection of 95%. Facility owners shall retrofit leak detection for facilities with pressurized piping by December 1, 1990, and facilities with suction piping by December 1, 1991. Leak detection methods are as follows:
A. Monthly statistical inventory reconciliation of daily product inventory data by an independent vendor using procedures approved by the United States Environmental Protection Agency. Pressurized piping must be retrofitted with an automated in-line leak detector; or [PL 2017, c. 333, §4 (AMD).]
B. Installation of one of the following leak detection systems:
(1) Secondary containment of all underground oil storage facility components or secondary containment for the tank and single-walled containment for suction piping sloped evenly to the tank and equipped with a single check valve under the pump;
(5) Automatic tank gauging that can detect a 0.2 gallon per hour loss, and to detect a leak or discharge of oil from product piping not installed in accordance with subparagraph (1), one of the following:
(a) Continuous vapor monitoring;
(b) Annual tightness testing;
(c) Secondary containment with interstitial space monitoring; or
(d) Other methods of leak detection approved by the department; or
(6) Other leak detection systems approved by the department that can detect a 0.2 gallon per hour leak rate or a leak of 150 gallons in 30 days with a 95% probability of detecting a leak and a 5% chance of false alarm. [PL 2017, c. 333, §4 (AMD).]
Existing piping must be equipped with leak detection. Pressurized piping must be equipped with an automated in-line leak detector and be monitored by a leak detection system listed in paragraph A or B. Suction piping must be installed to operate at less than atmospheric pressure, sloped to drain back into the tank with a loss of suction and installed with only one check valve located below and as close as practical to the suction pump. Product piping that does not meet these suction piping criteria must be monitored by a leak detection system listed in paragraph B.
[PL 2017, c. 333, §4 (AMD).]
1-B. Overfill and spill prevention equipment. Overfill and spill prevention equipment is required for all new, replacement and existing facilities. A phase-in schedule for existing facilities to meet this requirement is as follows.
