Section 2637 - Secondary Containment Testing(a) Secondary containment shall meet one of the following: (1) Test for tightness at all of the following times: (A) Upon installation of a secondary containment system, six months after installation of a secondary containment system, and at least once every 36 months thereafter;(B) On and after October 1, 2018 all of the following times:(i) Within 30 days of the date of the completion of a repair to a secondary containment component; and(ii) Within 30 days of the date of discontinuing the use of a method of continuous monitoring that automatically monitors the integrity of both the primary and secondary containment such as components that are hydrostatically monitored or under constant vacuum or pressure.(2) Use a method of continuous monitoring that automatically monitors the integrity of both the primary and secondary containment such as components that are hydrostatically monitored or under constant vacuum or pressure.(b) By December 31, 2002, the owner or operator of any secondary containment systems that the owner or operator determines cannot be tested in accordance with this section shall replace the secondary containment system with a system that can be tested in accordance with this section. As an alternative, the owner or operator may submit a proposal and workplan for enhanced leak detection to the local agency in accordance with subdivisions 2644.1(a)(1), (2), (4), and (5) by July 1, 2002; complete the program of enhanced leak detection by December 31, 2002; and replace the secondary containment system with a system that can be tested in accordance with this section by July 1, 2005. The local agency shall review the proposed program of enhanced leak detection within 45 days of submittal or re-submittal.(c) The testing of secondary containment systems shall be conducted using a test procedure that demonstrates that the system performs at least as well as it did upon installation. For example, if the secondary containment system was tested upon installation by using a test method that applied a pressure of five pounds per square inch, then the periodic test must be conducted using a method that tests the system at an equivalent pressure. These tests shall be performed in accordance with manufacturer's guidelines or standards. If there are no manufacturer's guidelines or standards, secondary containment systems must be tested using an applicable method specified in an industry code or engineering standard. If there are no applicable manufacturer's guidelines, industry codes, or engineering standards, a test method approved by a state registered professional engineer shall be used.(d) Secondary containment tests shall be performed by a service technician meeting the requirements of section 2715(f).(e) On and after October 1, 2018, the results of the secondary containment test shall be recorded on the "Secondary Containment Testing Report Form" located in Appendix VII.(f) On and after October 1, 2018, underground storage tank owners and operators shall submit a copy of the "Secondary Containment Testing Report Form" to the local agency within 30 days of the completion of the secondary containment test.(g) Owners and operators of underground storage tanks must notify the local agency at least 48 hours prior to conducting the secondary containment test.Cal.
