Current through February 27, 2024
(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.
