Section 7:14B-6.3 - Requirements for underground storage tank systems containing hazardous substances other than petroleum products and waste oil

(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.
