Current through Register Vol. 54, No. 28, July 13, 2024
(a) Owners
						  and operators of underground storage tank systems that store petroleum
						  installed after November 10, 2007, and underground piping installed after
						  November 10, 2007, that routinely contain regulated substances shall perform
						  interstitial monitoring in accordance with §
													245.444(6)
						  (relating to methods of release detection for tanks) at least once every 30
						  days. Underground piping installed after November 10, 2007, that conveys
						  regulated substances under pressure must be equipped and operated with an
						  automatic line leak detector with an automatic pump shut off device in
						  accordance with §
													245.445(1)
						  (relating to methods of release detection for piping). Release detection is not
						  required for suction piping that meets the requirements in subsection
						  (b)(2)(ii)(A)-(E).
(b) Owners and
						  operators of petroleum underground storage tank systems installed on or before
						  November 10, 2007, shall provide release detection for tanks and piping as
						  follows:
(1)
Tanks.
Tanks
						  shall be monitored at least every 30 days for releases using one of the methods
						  in § 245.444(1)-(8).
(2)
Piping.
Underground piping that routinely contains regulated
						  substances shall be monitored for releases in a manner that meets one of the
						  following requirements:
(i)
Pressurized piping
. Underground piping that conveys regulated
						  substances under pressure shall meet the following requirements:
(A) Be equipped with an automatic line leak
						  detector in accordance with §
																245.445(1)
						  (relating to methods of release detection for piping).
(B) Have an annual line tightness test
						  conducted in accordance with §
																245.445(2) or
						  have monthly monitoring conducted in accordance with §
																245.445(3).
(ii)
Suction piping
.
						  Underground piping that conveys regulated substances under suction shall either
						  have a line tightness test conducted at least every 3 years and in accordance
						  with §
															245.445(2), or
						  use a monthly monitoring method conducted in accordance with §
															245.445(3).
						  Release detection is not required for suction piping that is designed and
						  constructed to meet the following standards:
(A) The below grade piping operates at less
						  than atmospheric pressure.
(B) The
						  below grade piping is sloped so that the contents of the pipe will drain back
						  into the storage tank if the suction is released.
(C) No more than one check valve is included
						  in each suction line.
(D) Check
						  valves are located directly below and as close as practical to or within the
						  suction pump.
(E) A method is
						  provided that allows compliance with clauses (B)-(D) to be readily
						  determined.
