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 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 [see 2631 (d) (6)] 6. All tanks shall be installed according to a code of practice developed in accordance with voluntary consensus standards and the manufacturer's installation instructions 7. All tanks subject to floatation shall be anchored The two types of cathodic protection for new steel tanks are: 1. Field installed system (e.g., impressed current system) a. Must be designed and certified by a corrosion specialist b. Must be inspected every 60 days 2. Fiberglass, composites, or equivalent non-metallic exterior coverings, including sacrificial anode systems a. Must be tested at the installation site b. Sacrificial anode systems must be checked every 3 years All new underground storage tanks shall be equipped with spill containers and an overfill prevention system that meets the following requirements: 1. The spill container shall collect any hazardous material spilled during product delivery operations 2. The overfill prevention shall not allow manual override The spill containers (e.g., spill bucket) on all new tanks shall meet the following requirements: 1. If it is made of metal, the exterior wall shall be protected from corrosion 2. It shall have a minimum capacity of 5 gallons 3. It shall have a drain valve which allows drainage back into the tank or provide a means to keep the spill container empty (e.g., hand pump) The overfill prevention system on all new tanks shall meet the following requirements: 1. Alert the transfer operator when the tank is 90% full by restricting flow, into the tank or triggering an audible and visual alarm (e.g., ball float valve with Veeder Root high-level alarm); OR 2. Restrict delivery of flow to the tank at least 30 minutes before the tank overfills, provided the restriction occurs when the tank is no more than 95% full; and activate an audible alarm at least 5 minutes before the tank overfills; OR 3. Provide positive shut-off of flow to the tank when the tank is filled to no more than 95% of capacity (e.g., flapper valve); OR 4. Provide positive shut-off of flow to the tank so that none of the fittings located on the top of the tank are exposed to product due to overfilling The local agency may waive the requirement for overfill prevention equipment where: 1. The tank fill point is in an observable area 2. The spill container is adequate to collect any overfill 3. The tank system is filled by transfers of no more than 25 gallons The secondary containment system for all new underground tanks shall: 1. Encompass the entire primary system 2. Prevent the inflow of groundwater 3. Drainage of the liquid within the secondary shall be controlled in manner approved by the local agency to prevent discharge into the environment 4. Underground systems must be protected by asphalt, concrete or similar barrier that extends a minimum of one foot beyond the boundary of the original excavation 5. The actual location of the tanks and piping shall be indicated on as-built drawing that are provided to the local agency Secondary containment systems that contain backfill in the interstitial space (e.g., excavation liners) shall: 1. Be evaluated to determine the movement of the leak and designed accordingly 2. Be constructed such that backfill material does not impede movement of the release 3. Be designed to optimize flow of a release to the monitoring/collection point Owners or their agents shall certify that the installation of the tanks and piping meets applicable requirements. This certification shall be made on a "Certificate of Compliance for Underground Storage Tank Installation Form C" Underground piping installed after July 1, 1987 shall have secondary containment that complies with requirements for new underground storage tanks. Exclusions to this requirement: 1. Vent or tank riser piping 2. Vapor recovery piping 3. Suction piping All corrodible (e.g., steel pipe) shall be protected against corrosion Primary piping in contact with hazardous substances shall be installed in a secondary containment system which may be a: 1. Secondary pipe 2. Vault 3. Lined trench Lined piping trenches used as secondary containment shall be: 1. Designed and constructed applicable codes and standards 2. Be constructed of a material compatible with the material stored 3. Evaluated by 3rd party 4. Covered and capable of supporting vehicle traffic New primary piping that operates under pressure and associated secondary containment shall be tested for tightness after installation in accordance with manufacturer's guidelines. In general, this test is performed at 110% of the piping operating pressure All new suction or gravity flow piping which cannot be isolated from the tank shall be tested after installation in conjunction with the volumetric tank test Underground piping and associated secondary containment shall be equipped and monitored as follow: 1. The system shall either activate an audible and visual alarm or stop the flow of product when a leak is detected 2. The system shall have automatic line leak detectors that is capable of detecting a 3 gph leak at 10 psi operating pressure within 1 hour 3. Other monitoring methods may be implemented if they are as effective as 1. and 2. above and are approved by the local agency 4. An annual line leak test that can detect a .1 gph must be conducted The required annual line leak test can be waived in the following requirements are met: 1. All secondary containment systems are equipped with continuous monitoring systems (e.g., double walled tanks with annular sensors and secondary product piping a that drains back to tank
