§ 245.31. Underground storage tank system testing requirements.

 (a)  Tightness testing activities shall be conducted by a Department-certified underground storage tank system tightness tester (UTT), except when performed by an owner or operator using installed automatic tank gauging or monitoring equipment meeting requirements in §  245.444(2) and (3) (relating to methods of release detection for tanks).

 (b)  Tightness testing shall be conducted in accordance with equipment manufacturer’s written instructions and using the recommended written practices, procedures and established test method protocols developed by the sources in §  245.132(a)(1) (relating to standards of performance).

 (c)  A failed valid tightness test will, regardless of the test method, constitute a suspected release, except as provided in §  245.304(b) (relating to investigation and reporting of suspected releases). A failed valid tightness test conducted as part of an investigation of a suspected release constitutes a confirmed release.

 (d)  A complete written test report shall be provided to the tank owner as documentation of test results within 20 days of the test. The test methodology, a certification that the test meets the requirements in §  245.444(2) or §  245.445(2) (relating to methods of release detection for piping), and sufficient test data, which were used to conclude that the underground storage tank system passed or failed the tightness test, shall be included in the test report.

 (e)  Certified underground storage tank system tightness testers (UTT) shall maintain complete records of tightness testing activities for a minimum of 10 years as provided in §  245.132(a)(3).

 (f)  Tests or evaluations of spill prevention and overfill prevention equipment, containment sumps and release detection equipment required under this chapter shall be performed by a Department-certified individual holding the appropriate certification category and documented on a form provided by the Department. Results shall be maintained onsite at the storage tank facility or at a readily available alternative site and shall be provided to the Department upon request.
