                Subpart C_General Operating Requirements

 

Sec.  280.31  Operation and maintenance of corrosion protection.



    All owners and operators of steel UST systems with corrosion 

protection must comply with the following requirements to ensure that 

releases due to corrosion are prevented for as long as the UST system is 

used to store regulated substances:

    (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 routinely contain regulated 

substances and 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:

    (1) Frequency. All cathodic protection systems must be tested within 

6 months of installation and at least every 3 years thereafter or 

according to another reasonable time frame established by the 

implementing agency; and

    (2) Inspection criteria. The criteria that are used to determine 

that cathodic protection is adequate as required by this section must be 

in accordance with a code of practice developed by a nationally 

recognized association.

    Note: National Association of Corrosion Engineers Standard RP-02-85, 

``Control of External Corrosion on Metallic Buried, Partially Buried, or 

Submerged Liquid Storage Systems,'' may be used to comply with paragraph 

(b)(2) of this section.

    (c) UST systems with impressed current cathodic protection systems 

must also be inspected every 60 days to ensure the equipment is running 

properly.

    (d) For UST systems using cathodic protection, records of the 

operation of the cathodic protection must be maintained (in accordance 

with Sec.  280.34) to demonstrate compliance with the performance 

standards in this section. These records must provide the following:

    (1) The results of the last three inspections required in paragraph 

(c) of this section; and

    (2) The results of testing from the last two inspections required in 

paragraph (b) of this section.
