A hydraulic lift tank 4. A liquefied petroleum gas tank 5. A septic tank 6. A sump, pit, pond or lagoon 7. A wastewater treatment tanks except if it is part of a UST system 8. A pipeline located in a refinery except if it is connected to an underground storage tank 9. A storm water or waste water collection system 10. Tanks containing radioactive materials that are covered by the Atomic Energy Act 11. An emergency containment tank that is normally empty 12. Drums located in a basement and which contain 55 gallons or less of a hazardous material 13. Underground storage tanks containing hazardous waste that are regulated by the DTSC 14. A tank and associated piping located in a vault or basement and which meets the requirements of section 25283.5 of the Health and Safety code Title An "existing underground storage tank" means any underground storage tank installed prior to January 1, 1984. Tank "ullage" is space between the product level and the top of the tank (i.e., it is the empty space within the tank) All new underground storage tanks including associated piping shall have primary and secondary containment The design and construction of the primary containment on all new tanks, including any integral secondary containment system, shall be approved by an independent testing organization in accordance with industry codes, voluntary consensus standards, or engineering standards The primary containment stem on all new tanks with or without an integral secondary containment system shall wear plates (striker plates) installed below all accessible openings. A secondary containment system for a new tank which is not an integral part of the of the primary containment shall be designed and constructed according to an engineering specification approved by a state registered professional engineer or according to a nationally recognized industry code or engineering standard. The following requirements apply to non-integral secondary containment on new tanks 1. Must contain 100% of the usable capacity of the primary containment for a single container 2. Must contain 150% of the largest container or 10% of the aggregate volume for multiple containers 3. If open to rainfall, must accommodate the amount of rain that could enter the system during a 24hour, 25-year storm in addition to the applicable volume in items 1 or 2 above. 4. If backfill material is placed in the secondary containment system, the system must meet specific standards [see 2631 (d) (3)] 5. Must be equipped with a collection system to accumulate, store and permit removal of any liquid within the system. 6. The floor of the system must be sloped to a collection sump and meet other design standards [see 2631 (d) (5)]. 7. If a membrane liner is used (e.g., excavation liner), the design shall meet specific design standards [seee 2631 (d) (6)] New underground storage tanks with secondary containment shall be designed and installed so that any loss of hazardous substance from the primary containment will be detected by an interstitial monitoring device or method. Owners or operators of new underground storage tanks shall implement a monitoring program that: 1. Is approved by the local agency and specified in the operating permit. 2. Includes either visual or mechanical monitoring of the interstitial space. A visual interstitial monitoring plan for new tanks shall include: 1. Inspection of all tank surfaces and the floor beneath the tank by direct viewing 2. Daily inspections except on weekends or recognized state and federal holiday. (This requirement can be reduced at the discretion of the local agency depending but shall not be less than weekly). 3. Recording of the liquid level in the tank at the time of each inspection. 4. Provisions for sample collection and analysis of any observed liquid release. If analysis determines that a release may have occurred, a tank integrity test must be conducted. A monitoring program that relies on the mechanical or electrical detection in the interstitial space shall include: 1. Continuous monitoring of the interstitial space 2. An audible and visual alarm system approved by the local agency 3. For methods where that use indirect monitoring to determine if a release has occurred (e.g., wet annular or continuous vacuum), the monitoring program shall specify the proposed methods for determining if a release has occurred All monitoring programs for new tank systems (whether visual or mechanical), shall contain the following: 1. A written procedure which establishes a. The frequency of performing the monitoring b. The methods and equipment, identified by name and model, to be used for performing the monitoring c. The location where the monitoring will be performed d. The name(s) and title(s) of the individual(s) responsible for performing the monitoring and/or maintaining the equipment
