18 Alaska Admin. Code § 78.025

Current through October 17, 2024

Section 18 AAC 78.025 - Performance standards for new USTs

(a)General requirements. In order to prevent or detect releases caused by manufacturing defects, structural failure, corrosion, or spills or overfills for as long as the UST is used to store petroleum, the owner or operator of a new UST shall meet the requirements of this section.

(b)Secondary containment and interstitial monitoring for tanks and piping installed on or after July 25, 2012 and before April 11, 2016. Tanks and piping installed on or after July 25, 2012 and before April 11, 2016 and within 1,000 feet of an existing community water system as defined under 18 AAC 80.1990(a), an existing potable water system as defined under 18 AAC 80.1990(a), or a sole source aquifer as defined under 18 AAC 75.990 must be in secondary containment and use interstitial monitoring for leaks. Secondary containment must be able to contain petroleum released from anywhere in the UST system until it is detected and removed, and must prevent a release of petroleum to the environment at any time during the operational life of the UST system. For the purposes of this subsection,

(1) in the case of a replacement of an existing tank or existing piping, secondary containment and interstitial monitoring is only required for the tank or piping being replaced; and

(2) the 1,000 feet must be measured from the closest part of the tank or piping to the closest part of the existing community water system, potable water system, or sole source aquifer, including well heads for groundwater, the location of the intake points for surface water, water lines, processing tanks and water storage tanks, water distribution and service lines under the control of the community water system operator, and the wellhead of the nearest existing potable drinking water well.

(c)Secondary containment and interstitial monitoring for tanks and piping installed on or after April 11, 2016. Tanks and piping installed on or after April 11, 2016 must be in secondary containment and use interstitial monitoring in accordance with 18 AAC 78.065(h), except for suction piping that meets the requirements of 18 AAC 78.060(f)(1)(B)(i) -(v). Secondary containment must be able to contain petroleum leaked from the primary containment until it is detected and the petroleum removed, and must prevent the release of petroleum to the environment at any time during the operational life of the UST. For cases where the piping is considered to be replaced, the entire piping run must be within secondary containment.

(d)Notification. At least 15 days, but not more than 60 days, before beginning installation of a UST, the owner or operator shall notify the department in writing that it will do so, on a form provided by the department.

(e)Tanks. Each tank must be properly designed, constructed, and installed in a manner that will prevent releases for its operating life due to manufacturing defects, structural failure, or corrosion, in accordance with a nationally recognized code of practice, and meet one of the following requirements:
