Closure


Closure of an underground storage tank is permitted by the DPW Environmental Programs Division. Closure by removal of an UST, piping and/or dispensers, the closure in-place of an UST and the temporary closure of an UST must comply with the closure conditions as directed on the Closure Permit as well as meet the requirements of California Health and Safety Code Division 20, Chapter 6.7, Section 25298, California Code of Regulations Title 23, Division 3, Chapter 16, Sections 2670 through 2672, and the Los Angeles County Code. It is the policy of Los Angeles County not to allow closure in-place of an UST unless it can be demonstrated from an engineering perspective that it is not feasible to remove the UST.
