New Jersey Administrative Code › Title 7 - ENVIRONMENTAL PROTECTION › Chapter 14B - UNDERGROUND STORAGE TANKS › Subchapter 6 - RELEASE DETECTION › Section 7:14B-6.3 - Requirements for underground storage tank systems containing hazardous substances other than petroleum products and waste oil

Current through Register Vol. 56, No. 14, July 15, 2024
(a) Owners and
				operators of underground storage tank systems containing hazardous substances
				other than petroleum products and waste oil shall provide release detection
				that meets the following requirements:
1.
				Release detection at underground storage tank systems installed before
				September 4, 1990, shall meet the requirements for petroleum underground
				storage tank systems in
N.J.A.C.
				7:14B-6.2
. All other underground
				storage tank systems containing hazardous substances other than petroleum
				products and waste oil shall meet the release detection requirements for
				underground storage tank systems in (a)2 below.
2. Release detection for underground storage
				tank systems containing hazardous substances other than petroleum and waste oil
				shall meet the following requirements:
i.
				Secondary containment systems shall be designed, constructed, and installed to:
(1) Contain regulated substances leaked from
				the UST system until they are detected and removed;
(2) Prevent the release of regulated
				substances to the environment at any time during the operational life of the
				underground storage tank system; and
(3) Be checked for evidence of a release at
				least every 30 calendar days.
ii. Double-walled tanks shall be designed,
				constructed, and installed to:
(1) Contain a
				leak from any portion of the inner tank within the outer wall; and
(2) Detect the failure of the inner
				wall.
iii. External
				liners (including vaults) shall be designed, constructed, and installed to:
(1) Contain 100 percent of the capacity of
				the largest tank within its boundary;
(2) Prevent the interference of precipitation
				or ground water intrusion with the ability to contain or detect a release of
				regulated substances; and
(3)
				Surround the tank completely so that the upper perimeter of the liner is above
				the top of the tank.
iv.
				Underground piping shall be equipped with secondary containment that satisfies
				the requirements of (a)2i above (for example, trench liners, jacketing of
				double-walled pipe). In addition, underground piping that conveys regulated
				substances under pressure shall be equipped with an automatic line leak
				detector in accordance with
				7:14B-6.6(a)1.
v. Other methods of release detection may be
				used for underground storage tank systems, containing hazardous substances
				other than petroleum and waste oil, installed before October 13, 2015, if
				owners and operators:
(1) Demonstrate to the
				Department that an alternate method can detect a release of the stored
				substance as effectively as any of the methods allowed in
				7:14B-6.5(a)2 
				through 6.5(a)8 can detect a release of petroleum;
(2) Provide information to the Department on
				effective corrective action technologies, health risks, and chemical and
				physical properties of the stored substance, and the characteristics of the
				underground storage tank site; and
(3) Obtain approval from the Department,
				through the issuance of a permit pursuant to N.J.A.C. 7:14B-10, to use the
				alternate release detection method before the installation and operation of the
				new underground storage tank system.
3. The provisions of
40 CFR
				265.193
, Containment and Detection
				of Releases, may be used to comply with the requirements of (a)2 above for
				tanks installed before April 11, 2016.
