17.56.302    OPERATION AND MAINTENANCE OF CORROSION PROTECTION

(1) All owners and operators of metal UST systems with corrosion protection shall comply with the following requirements to ensure that releases due to corrosion are prevented until the UST system is permanently closed or undergoes a change-in-service pursuant to ARM Title 17, chapter 56, subchapter 7:

(a) all corrosion protection systems must be operated and maintained to continuously provide corrosion protection to the metal components of that portion of the tank and piping that are in contact with the ground;

(b) all UST systems equipped with cathodic protection systems must be inspected for proper operation by a qualified cathodic protection tester in accordance with the following requirements:

(i) all cathodic protection systems must be tested within six months of installation and at least every three years thereafter; and

(ii) the criteria that are used to determine that cathodic protection is adequate as required by this rule must be in accordance with one of the codes of practice listed in (2);

(c) UST systems with impressed current cathodic protection systems must also be inspected every 60 days to ensure the equipment is running properly; and

(d) for UST systems using cathodic protection, records of the operation of the cathodic protection must be maintained in accordance with ARM 17.56.305 to demonstrate compliance with the performance standards in this rule. These records must provide the following:

(i) the results of the last three inspections required in (1)(c); and

(ii) the results of testing from the last two inspections required in (1)(b).

(2) The department adopts and incorporates by reference the version in effect on January 1, 2018, of the following standards and test methods:
