Utah Admin. Code R311-203-6 - Secondary Containment and Under-Dispenser Containment
(1) Secondary containment for tanks and
piping.
(a) to meet the requirements of
Subsection 42 USC
6991b(i) of the Solid Waste
Disposal Act, tanks and product piping that are installed as part of an UST
system after October 1, 2008 and before January 1, 2017 must have secondary
containment if the installation is located 1,000 feet or less from an existing
community water system or an existing potable drinking water well.
(b) the secondary containment installed under
Subsection R311-203-6(1) must meet the requirements of
40 CFR
280.42(b), and shall be
monitored monthly for releases from the tank and piping.
(i) monthly monitoring must meet the
requirements of 40 CFR
280.43(g).
(c) containment sumps for piping
installed under Subsection R311-203-6(1) are required:
(i) at the submersible pump or other location
where the piping connects to the tank;
(ii) where the piping connects to a
dispenser, or otherwise goes aboveground; and
(iii) where double-walled piping that is
required under Subsection R311-203-6(1) connects with existing
piping.
(d) containment
sumps for piping that is installed under Subsection R311-203-6(1) must:
(i) contain submersible pumps, check valves,
unburied risers, flexible connectors, and other transitional components that
connect the piping to the tank, dispenser, or existing piping; and
(ii) meet the requirements of Subsection
R311-203-6(2)(b).
(e) in
the case of a replacement of tank or piping, only the portion of the UST system
being replaced is subject to the requirements of Subsection R311-203-6(1).
(i) if less than 100% of the piping from a
tank to a dispenser is replaced, the requirements of Subsection R311-203-6(1)
applies to new product piping that is installed.
(ii) the closure requirements of Rule
R311-205 apply to product piping that is taken out of service.
(iii) when new piping is connected to
existing piping that is not taken out of service, the connection between the
new and existing piping must be secondarily contained, and monitored for
releases according to 40 CFR
280.43(g).
(f) the requirements of Subsection
R311-203-6(1) do not apply to:
(i) piping that
meets the requirements for "safe suction" piping in
40 CFR
280.41(b)(2); or
(ii) piping that connects two or more tanks
to create a siphon system.
(g) the requirements of Subsection
R311-203-6(1) apply to emergency generator USTs installed after October 1,
2008.
(2)
Under-dispenser containment.
(a) to meet the
requirements of Subsection 42 USC 6991b(i)
of the Solid Waste Disposal Act, new motor fuel dispenser systems installed
after October 1, 2008 and before January 1, 2017, and connected to an UST, must
have under-dispenser containment if the installation is located 1,000 feet or
less from an existing community water system or an existing potable drinking
water well.
(b) the under-dispenser
containment must:
(i) be liquid-tight on its
sides, bottom, and at penetrations;
(ii) be compatible with the substance
conveyed by the piping; and
(iii)
allow for visual inspection and access to the components in the containment
system, or be continuously monitored for the presence of liquids.
(c) if an existing dispenser is
replaced, the requirements of Subsection R311-203-6(2) apply to the new
dispenser if any equipment used to connect the dispenser to the PST system is
replaced.
(i) this equipment includes
unburied flexible connectors, risers, and other transitional components that
are beneath the dispenser and connect the dispenser to the product
piping.
(3)
The requirements of Subsections R311-203-6(1) and R311-203-6(2) do not apply if
the installation is located more than 1,000 feet from an existing community
water system or an existing potable drinking water well.
(a) the PST owner or operator must provide to
the director documentation to show that the requirements of Subsections
R311-203-6(1) and R311-203-6(2) do not apply to the installation.
(b) the documentation shall be provided at
least 60 days before the beginning of the installation, and shall include:
(i) a detailed to-scale map of the proposed
installation that demonstrates that no part of the installation is within 1,000
feet of any community water system, potable drinking water well, or any well
the owner or operator plans to install at the facility; and
(ii) a certified statement by the owner or
operator explaining who researched the existence of a community water system or
potable drinking water well, how the research was conducted, and how the
proposed installation qualifies for an exemption from the requirements of
Subsections R311-203-6(1) and R311-203-6(2).
(4) To determine whether the requirements of
Subsections R311-203-6(1) and R311-203-6(2) apply, the distance from the UST
installation to an existing community water system or existing potable drinking
water well shall be measured from the closest part of the new UST, piping, or
motor fuel dispenser system to:
(a) the
closest part of the nearest community water system, including:
(i) the location of the wellheads for
groundwater and the location of the intake points for surface water;
(ii) water lines, processing tanks, and water
storage tanks; and
(iii) water
distribution/ and service lines under the control of the community water system
operator, or
(b) the
wellhead of the nearest existing potable drinking water well.
(5) If a new UST facility is
installed, and is not within 1,000 feet of an existing community water system
or an existing potable drinking water well, the requirements of Subsections
R311-203-6(1) and R311-203-6(2) apply if the owner or operator installs a
potable drinking water well at the facility that is within 1,000 feet of the
UST, piping, or motor fuel dispenser system, regardless of the sequence of
installation of the UST system, dispenser system, and well.
