-s - advise the requester of the manner in which the request is incomplete and allow a reasonable time within which an amended request may be submitted. If the UST Program Manager does not receive an adequate amended petition within the time allowed, the request for reconsideration may be denied. What does it mean if the ELD test results indicate that the UST system has "failed"? Note: The following information is based upon the Enhanced Tracer Tight@ test performed by Praxair Services, Inc. (formerly known as Tracer Research Corporation). As other test methods become available, we will prepare additional information if appropriate. A "fail" test result indicates that a substance that is not a component of the fuel formulation stored in that UST system (referred to as a "tracer" by Praxair Services, Inc.) has escaped from the UST system. Based upon the distribution and concentration of tracer detected in the soil gas samples collected around the UST system, Praxair Services, Inc. is able to infer the location, relative size, and type of release (liquid versus vapor). What action(s) must be taken if the UST system "fails" the ELD test? Pursuant to the UST regulations, if the UST system fails the ELD test, it may be an indication of an unauthorized release, 4 and the owner/operator must notify the local agency within 60 days after the ELD test has been completed. [Cal. Code Regs., Title 23, § 2644.1, subd. (a)(5)3 In addition, the owner/operator should review the test report and implement any necessary repairs or corrections to the system. Once the UST system has been fixed, the ELD test must be repeated to confirm that the UST system is no longer leaking liquid or vapor. [Health & Saf. Code, §§ 25292.4, subd. (d), 25292.5, subd. (c)j If an unauthorized release is confirmed, the owner/operator must comply with the requirements of California Code of Regulations, Title 23, Article 5. Pursuant to section 2652(a), within 24 hours after an unauthorized release has been detected, the owner/operator must notify the local agency, investigate the condition, and take immediate measures to stop the release. Pursuant to section 2652 (b), if necessary or as required by the local agency, the owner/operator must remove the remaining stored substance from the UST system to prevent further releases to the environment or to facilitate corrective action. 4 See Health & Saf. Code, § 25281, subd. (o), defining a "release" as "any spilling, leaking, emitting, discharging, escaping, leaching, or disposing from an underground storage tank into or on the waters of the state, the land, or the subsurface soils.
