Current through Register Vol. 56, No. 21, November 4, 2024

Section 7:14B-6.1 - General requirements for all underground storage tank systems

(a) Owners and operators of underground storage tank systems shall provide a method, or combination of methods, of release detection that:

1. Can detect a release from any portion of the tank and the connected underground piping that routinely contains product;

2. Is installed, calibrated, operated, and maintained in accordance with the manufacturer's instructions, including routine maintenance and service checks for operability or running condition; and

3. Meets the performance requirements in N.J.A.C. 7:14B-4A, 6.5, or 6.6, as applicable, with any performance claims and the manner of determination of the performance claims described in writing by the equipment manufacturer or installer. Permanent methods installed on or after September 4, 1990, shall be capable of detecting the leak rate or quantity specified for that method in the corresponding section of the rule with a probability of detection (Pd) of 0.95 and a probability of false alarm (Pfa) of 0.05.

(b) Owners and operators of underground storage tank systems used to store motor fuel solely for use by an emergency power generator shall comply with the requirements of this subchapter in accordance with the following:

1. Systems for which installation began on or before October 13, 2015, shall comply with N.J.A.C. 7:14B-6 on or before October 13, 2018, or the date provided at 40 CFR 280.10, whichever is later; and

2. Systems for which installation begins after October 13, 2015, shall comply with all applicable requirements of this chapter at installation.

(c) Underground storage tank systems with field constructed tanks and airport hydrant systems shall meet release detection requirements in accordance with N.J.A.C. 7:14B-4A.

(d) When a release detection method operated in accordance with the performance standards in N.J.A.C. 7:14B-4A or 6.5 and 6.6 indicates a release may have occurred, owners and operators shall notify the Department in accordance with N.J.A.C. 7:14B-7.

(e) Any underground storage tank system regulated pursuant to 58:10A-21 et seq. and 42 U.S.C. §§ 6991 et seq. that cannot apply a method of release detection that complies with the requirements of this subchapter shall complete the closure procedures in N.J.A.C. 7:14B-9.

(f) Each owner and operator of any underground storage tank system regulated pursuant to 58:10A-21 et seq., but not 42 U.S.C. §§ 6991 et seq., that cannot apply a method of release detection with the requirements of this subchapter shall complete the closure requirements of N.J.A.C. 7:14B-9 pursuant to a closure schedule that the Department has approved.

(g) On or before October 13, 2018, or the date provided at 40 CFR 280.40, whichever is later, owners and operators shall ensure that all underground storage tank systems, including electronic and mechanical components, are operated, maintained, and tested in accordance with the following:

1. Requirements developed by the manufacturer, if any;

2. A code of practice developed by a nationally recognized association or independent testing laboratory, such as Petroleum Equipment Institute Recommended Practice RP1200, "Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection, and Secondary Containment Equipment at UST facilities" (available at www.pei.org); or

3. A method that the owner and operator demonstrates is no less protective of human health and the environment than the requirements of (g)1 and 2 above.

(h) Testing of electronic and mechanical components in accordance with (g) above shall be performed at least annually and shall include, as applicable, the following:

1. For automatic tank gauge and other controllers: testing alarm, verifying system configuration, and testing battery backup;

2. For probes and sensors: inspecting for residual buildup and ensuring floats move freely, ensuring shaft is not damaged, ensuring cables are free of kinks and breaks, and ensuring that the alarm is operable and communicates with the controller;

3. For automatic line leak detectors: ensuring that the detectors meet the criteria at N.J.A.C. 7:14B-6.6(a)1;

4. For vacuum pumps and pressure gauges: ensuring proper communication with sensors and controller; and

5. For handheld electronic sampling equipment associated with ground water and vapor monitoring: ensuring proper operation.
