§ 245.613. Monitoring standards.
(a) By October 12, 1998, a method of leak detection shall be in use and monitored at least monthly. An automatic sensing device, mechanical device or other appropriate method may be used. This method, at a minimum, shall provide a visual examination of the storage tank system by the owner and operator or designated representative. If releases are detected, they shall be corrected and the provisions of Subchapter D (relating to corrective action process for owners and operators of storage tanks and storage tank facilities and other responsible parties) shall be complied with.
(b) The owner and operator shall assure that a maintenance and general operations check of the aboveground storage tank system is performed at least monthly. Deficiencies noted during the check shall be corrected. The small aboveground storage tank general operations and maintenance checklist provided by the owner and operator shall be used to document the monthly operations and maintenance check. The operations and maintenance check shall include:
(1) A visual examination of the aboveground storage tank system for deterioration, including the tank, piping, ancillary equipment, foundation, containment structure or facility, and safety equipment.
(2) A check of the containment areas for accumulation of water and removal of water as necessary.
(3) Confirmation that containment drain valves are secured in the closed position when not in use.
(4) Verification of the functionality of the leak detection system.
(5) A check of vents for restrictions.
(6) A check of ancillary equipment for operational malfunctions.
(7) An investigation of conditions that may be a fire or safety hazard, or pose an environmental hazard.
(8) Observation for evidence of a release of regulated substance from the aboveground storage tank system.
(c) An owner and operator of an aboveground storage tank system with a cathodic protection system must comply with the following requirements to ensure that releases due to corrosion are prevented for as long as the aboveground storage tank system is used to store regulated substances:
(1) An aboveground storage tank system equipped with a cathodic protection system must be tested for proper operation by a qualified cathodic protection tester in accordance with the following requirements:
(i) Impressed current cathodic protection systems must be tested at least annually.
(ii) Galvanic cathodic protection systems must be tested at least every 3 years.
(iii) Cathodic protection systems must be tested within 6 months following installation and 6 months following repair of the cathodic protection system.
(iv) 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.
(2) An aboveground storage tank system 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 shall 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.
(3) For an aboveground storage tank system using cathodic protection, records of the operation of the cathodic protection system must be maintained under § 245.615 (relating to recordkeeping requirements) to demonstrate compliance with the performance standards in this section. The records must include the following:
(i) The results of the last three checks required in paragraph (2).
(ii) The results of testing from the last two cathodic protection surveys required in paragraph (1).
