Universal Citation: NJ Admin Code 7:14B-7.2

Current through Register Vol. 56, No. 18, September 16, 2024

(a) The owner and operator shall confirm or disprove a suspected release by conducting an investigation in accordance with all of the applicable following procedures:

1. Check inventory control records for mathematical accuracy;

2. Conduct a visual inspection of all readily accessible physical facilities for evidence of leakage or discharge;

3. Check the calibration of all dispenser meters associated with hazardous substance withdrawal and if necessary perform calibration;

4. Check for a malfunction of the monitoring system;

5. If the release is suspected due to the results of a previously conducted precision test which indicated that a release occurred, then an additional precision tank test shall be conducted on the underground storage tank system in accordance with 7:14B-6.5(a)3, if the test results indicated the following:
i. The results were inconclusive due to failure of the test to take into account and compensate for those factors outlined in 7:14B-6.5(a) 3; or

ii. There were loose fittings not associated with any product bearing part of the tank system or above the holding capacity of the tank where an overfill device has been installed pursuant to this chapter; or

6. Determine whether there are any photoionization detector readings above 50 meter units in soil or ground water.

7. Conduct testing of tanks, piping, or secondary containment as appropriate, according to N.J.A.C. 7:14B-5.4(a) 4 or 5, 6.5(a)3, or 6.6(a)2, in order to determine:
i. The portion of the tank that routinely contains product, or associated product bearing piping has a leak; or

ii. There is a breach of either wall of the secondary containment.

(b) If the investigation conducted in accordance with (a) above is inconclusive in confirming or disproving a suspected release, the owner and operator shall, in accordance with the schedule in the Technical Requirements for Site Remediation, at N.J.A.C. 7:26E-3.14, conduct and complete a site investigation designed to confirm or disprove a suspected discharge in accordance with the Technical Requirements for Site Remediation, at N.J.A.C. 7:26E-3.3. If a discharge is confirmed, the owner and operator shall initiate action pursuant to N.J.A.C. 7:14B-7.3. The owner and operator shall keep documentation of an investigation in accordance with this section that disproves a suspected discharge at the facility and make it available for inspection by the Department for the operational life of the underground storage tank system.

(c) If the owner or operator concludes in the site investigation report submitted pursuant to N.J.A.C. 7:26E-3.14that no further remediation is required, then the licensed site remediation professional shall issue a response action outcome to the owner or operator pursuant to the Administrative Requirements for the Remediation of Contaminated Sites at N.J.A.C. 7:26C-6.

(d) If the owner or operator concludes in the site investigation report submitted pursuant to N.J.A.C. 7:26E-3.14that further remediation is required, then the owner or operator shall conduct additional remediation pursuant to the Administrative Requirements for the Remediation of Contaminated Sites at N.J.A.C. 7:26C, and the Technical Requirements for Site Remediation at N.J.A.C. 7:26E
