(a) The board shall take all of the following actions with regard to the prevention of unauthorized releases from petroleum underground storage tanks: (1) On or before June 1, 2000, initiate a field-based research program to quantify the probability and environmental significance of releases from underground storage tank systems meeting the 1998 upgrade requirements specified in Section 25284, as that section read on January 1, 2002. The research program shall do all of the following: (A) Seek to identify the source and causes of releases and any deficiencies in leak detection systems. (B) Include single-walled, double-walled, and hybrid tank systems, and avoid bias towards known leaking underground storage tank systems by including a statistically valid sample of all operating underground storage tank systems. (C) Include peer review. (2) Complete the research program on or before June 1, 2002. (3) Use the results of the research program to develop appropriate changes in design, construction, monitoring, operation, and maintenance requirements for tank systems. (4) On or before January 1, 2001, adopt regulations to do all of the following: (A) (i) Require underground storage tank owners, operators, service technicians, installers, and inspectors to meet minimum industry established training standards and require tank facilities to be operated in a manner consistent with industry established best management practices. (ii) The board shall implement an outreach effort to educate small business owners or operators on the importance of the regulations adopted pursuant to this subparagraph. (B) (i) Except as provided in clauses (ii) and (iii), require testing of the secondary containment components, including under-dispenser and pump turbine containment components, upon initial installation of a secondary containment component and periodically thereafter, to ensure that the system is capable of containing a release from the primary containment until the release is detected and cleaned up. The board shall consult with the petroleum industry and local governments to assess the appropriate test or tests that would comply with this subparagraph. (ii) Secondary containment components that are part of an emergency tank system may be tested using enhanced leak detection, if the test is performed at the frequency specified by the board for testing of secondary containment pursuant to Section 2644.1 of Title 23 of the California Code of Regulations. If the results of the enhanced leak detection test indicate that any component of the emergency tank system is leaking liquid or vapor, the owner or operator shall take appropriate actions to correct the leakage, and the owner or operator shall retest the system using enhanced leak detection until the system is no longer leaking liquid or vapor. (iii) Any tank or piping that is part of an emergency tank system and located within a structure as described in paragraph (2) of subdivision (a) of Section 25283.5 is exempt from the secondary containment testing required by clause (i) if the owner or operator conducts a visual inspection of the tank or piping each time the tank system is operated, but no less than monthly, and maintains a log of inspection results for review by the local agency. This clause does not apply if the board adopts regulations pursuant to Section 25299.3 that address the design, construction, upgrade, and monitoring of unburied tanks that are part of an emergency tank system. (C) Require annual testing of release detection sensors and alarms, including under-dispenser and pump turbine containment sensors and alarms. The board shall consult with the petroleum industry and local governments to assess the appropriate test or tests that would comply with this subparagraph. (5) (A) Require an owner or operator of an underground storage tank installed after July 1, 1987, if a tank is located within 1,000 feet of a public drinking water well, as identified pursuant to the state GIS
