N.J. Admin. Code § 7:14B-5.2 - Operation and maintenance of corrosion protection

(a) All owners and operators of metallic underground storage tank systems with corrosion protection shall comply with the following requirements to ensure that releases due to corrosion are prevented for as long as the underground storage tank system is used to store regulated substances:

1. All corrosion protection systems shall be operated and maintained in accordance with (a)2 and 3 below to continuously provide corrosion protection to the metal components of that portion of the tank and piping that routinely contain regulated substances and are in contact with the ground.

2. All underground storage tank systems equipped with cathodic protection systems shall be inspected for proper operation by a Cathodic Protection Tester or Cathodic Protection Specialist certified pursuant to N.J.A.C. 7:14B-13 in accordance with the following requirements:

i. All cathodic protection systems shall be tested within six months of installation and at least every three years thereafter by an individual certified in accordance with N.J.A.C. 7:14B-13; and

ii. The criteria that are used to determine that cathodic protection is adequate as required by this section shall be in accordance with the following codes of practice, as applicable, incorporated herein by reference, as amended and supplemented:

(1) NACE International Test Method TM 0101, "Measurement Techniques Related to Criteria for Cathodic Protection on Underground or Submerged Metallic Tank Systems" (available at www.nace.org);

(2) NACE International Test Method TM0497, "Measurement Techniques Related to Criteria for Cathodic Protection on Underground or Submerged Metallic Piping Systems" (available at www.nace.org);

(3) Steel Tank Institute Recommended Practice R051, "Cathodic Protection Testing Procedures for sti-P3 USTs" (available at www.steeltank.com);

(4) NACE International Recommended Practice RP-02-85, "Control of Underground Storage Tank Systems by Cathodic Protection" (available at www.nace.org); or

(5) NACE International Standard Practice SP 0169, "Control of External Corrosion on Underground or Submerged Metallic Piping Systems" (available at www.nace.org).

3. Underground storage tank systems with impressed current cathodic protection systems shall be inspected every 60 calendar days to ensure the equipment is running properly.

4. For underground storage tank systems using cathodic protection, records of the operation of the cathodic protection shall be maintained in accordance with 7:14B-5.6 to demonstrate compliance with the operation and maintenance standards in this section. These records shall provide the following:

i. The results of testing from all inspections required in (a)2 above; and
