of USTs.
This update
covers:
- licenses required to apply interior lining in a UST;
- licenses required to install a bladder system in a UST;
- licenses required to install corrosion protection systems onto USTs; and
- change in policy regarding the hazardous substance certification requirement for interior lining contractors.
Licensing
Any work to upgrade, install, or remove USTs is subject
to contractor licensing if the total cost of such work
is $300 or more. Under current Contractors State License
Board (CSLB) policy only those contractors holding one
of the following classifications are properly licensed
to contract for such work:
- General
Engineering Contractor (A) - General engineering contractors
may work on underground storage tanks for any purpose
whatsoever at any location.
- General Building Contractor (B) - General building

Hazardous Substance Certification
In accordance with the provisions of Business and Professions Code (B&P) Section 7058.7, a contractor must possess a Hazardous Substance Certification issued by the CSLB to:
- install
or remove an underground storage tank. However,
a contractor who is not certified may bid on or contract
for the installation or removal, as long as the work
is performed by a contractor who is certified.
- upgrade an underground storage tank. Upgrading means installation
of a bladder system, application of interior lining,
and installation of striker plates that are permanent
bonded to the tank bottom. A contractor does not need
to possess this certification to install spill containment
or overfill prevention devices, fill pipes, vapor
recovery systems, or leak detection equipment. Again,
a contractor who is not certified may bid on or contract
for the installation or removal, as long as the work
is performed by a contractor who is certified.
- engage in removing or remedying the release of a hazardous substance at the site or to correct the conditions that threaten the release of a hazardous substance (pursuant to Sections 25355.5 and 25356 Health and Safety Code). Per Section 7058.7, "removal or remedial action" refers to work in which the contractor digs into the surface of the earth and removes the dug material and the work is at a hazardous substance release site as identified in Section 25356 H&SC. These provisions of the Health and Safety Code apply to hazardous substances other than petroleum. Therefore, the hazardous substance certification is not required for corrective action at petroleum UST sites.
