       ARTICLE __.  CONTAINMENT SYSTEMS REQUIRED FOR CERTAIN
                     UNDERGROUND STORAGE TANKS
      SECTION _. Subchapter I, Chapter 26, Water Code, is amended
by adding Section 26.3476 to read as follows:
      Sec. 26.3476.  SECONDARY CONTAINMENT REQUIRED FOR TANKS
LOCATED OVER CERTAIN AQUIFERS. (a)  In this section, "secondary
containment" means a method by which a secondary wall or barrier is
installed around an underground storage tank system in a manner
designed to prevent a release of a regulated substance from
migrating beyond the secondary wall or barrier before the release
can be detected.  A secondary containment system may include an
impervious liner or vault surrounding a primary tank or piping
system or a double-wall tank or piping system.
      (b)  An underground storage tank system, at a minimum, shall
incorporate a method for secondary containment if the system is
located in:
            (1)  the outcrop of a major aquifer composed of
limestone and associated carbonate rocks of Cretaceous age or
older; and
            (2)  a county that:
                  (A)  has a population of at least one million and
relies on groundwater for at least 75 percent of the county's water
supply; or
                  (B)  has a population of at least 75,000 and is
adjacent to a county described by Paragraph (A).
      (c)  Section 26.3475(e) applies to an underground storage
tank system that is subject to this section as if a violation of
this section were a violation of Section 26.3475.
      (d)  This section does not prohibit the commission or a
political subdivision from adopting additional or more stringent
requirements regarding methods for containment of underground
storage tank systems if those requirements are compatible with the
requirements of this section.
      (2)  On page 114, between lines 17 and 18, insert the
following section, appropriately numbered:
      SECTION _.  CONTAINMENT SYSTEMS REQUIRED FOR CERTAIN
UNDERGROUND STORAGE TANKS. The change in law made by Section
26.3476, Water Code, as added by this Act, applies only to an
underground storage tank system that is installed, upgraded, or
replaced on or after the effective date of this Act.
      (3)  Renumber the articles and sections of the committee
substitute accordingly.
