25 Pa. Code § 245.532. Cathodic protection systems.

§ 245.532. Cathodic protection systems.

 (a)  When required for corrosion prevention, cathodic protection systems must consist of one or more of the following:

   (1)  Sacrificial anodes and dielectric coating.

   (2)  Impressed current.

   (3)  Another method specified in an appropriate Nationally recognized association code of practice.

 (b)  Cathodic protection systems shall be designed by a corrosion expert and maintained to provide protection against external corrosion for the operational life of the tank system.

 (c)  Each cathodic protection system shall have an access point which enables the owner or operator to check on the adequacy of cathodic protection. The cathodic protection systems shall be tested for proper operation by a qualified cathodic protection tester in accordance with the following requirements:

   (1)  Impressed current cathodic protection systems must be tested at least annually.

   (2)  Galvanic cathodic protection systems must be tested at least every 3 years.

   (3)  Cathodic protection systems must be tested within 6 months following installation and 6 months following repair of the cathodic protection system.

   (4)  The criteria that are used to determine that cathodic protection is adequate under this section must be in accordance with a code of practice developed by a Nationally recognized association.

 (d)  Aboveground storage tank systems with impressed current cathodic protection systems must be checked every 60 days to ensure the equipment is running properly. At a minimum, the operator or person conducting the 60-day check must document the date checked, annotate the system’s functioning status, and for systems equipped with a direct current readout meter, record the amount of current indicated on the meter.

 (e)  For aboveground storage tank systems using cathodic protection, records of the operation of the cathodic protection must be maintained under §  245.516 (relating to recordkeeping requirements) to demonstrate compliance with the performance standards in this section. The records must include the following:

   (1)  The results of the last three checks required in paragraph (d).

   (2)  The results of testing from the last two cathodic protection surveys required in paragraph (c).

 (f)  Tank and piping connections of two dissimilar metals which create a galvanic cell are prohibited.
