Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Bladder systems may be installed in tanks which store motor vehicle fuel only,
				  may be used to satisfy part of the upgrade requirements in section
				  2662, and shall be installed and
				  operated in accordance with this section.
(b) Materials used in the bladder system and
				  in the installation process shall be approved by an independent testing
				  organization based on voluntary consensus standards, an industry code, or
				  engineering standard for the applicable use of the bladder system. Evidence of
				  this approval shall be provided to the local agency before the local agency
				  authorizes the installation. The following conditions shall be met:
(1) The bladder system shall be installed
				  under the direct supervision of a representative of the bladder system
				  fabricator or a contractor certified by the fabricator.
(2) The entire interstitial space between the
				  tank and the bladder shall be monitored in accordance with subdivision
				  2632(c)(2).
(3) Materials used in the bladder system
				  shall be product-tight and compatible with the substance stored.
(4) The bladder system shall include an
				  internal striker plate (wear plate) which meets the requirements of section
				  2631(c).
(5) If the underground storage tank is
				  constructed of steel, cathodic protection shall be installed in accordance with
				  section 2635(a)(2)(A)
				  and, before installing a bladder system, a special inspector shall certify that
				  the underground storage tank has sufficient structural integrity to seal the
				  interstitial space between the bladder and the underground storage tank and
				  provide secondary containment. The special inspector shall make this
				  certification by entering and inspecting the entire interior surface of the
				  tank and shall base this certification upon the set of procedures and criteria
				  specified in section
				  2663(b)(2),
				  except that abrasive blasting is only required to the extent deemed necessary
				  by manufacturers' specifications, or the special inspector, to assess the
				  structural integrity of the underground storage tank.
(6) The bladder installer shall certify in
				  writing that sufficient measures have been taken to minimize or eliminate the
				  potential for the underground storage tank or interstitial monitoring system
				  components to puncture the bladder. The tank owner shall submit the
				  certification to the local agency through the California Environmental
				  Reporting System or a local reporting portal.
(7) Before installing a bladder, thin areas
				  or other flaws in the underground storage tank walls that need additional
				  reinforcing shall be reinforced in accordance with section
				  2661(d).
(8) If required by manufacturers'
				  specifications or the special inspector, the underground storage tank shall be
				  lined in accordance with section
				  2663 prior to installation of the
				  bladder only to the thickness deemed necessary by the more stringent
				  requirement of the manufacturers' specifications or the special
				  inspector.
