(a) All Class V aquifer storage and recovery (ASR)
injection wells shall be operated in such a manner that injection
will not endanger drinking water sources. Underground injection endangers
drinking water sources if such injection may result in the presence
in underground water which supplies or can reasonably be expected
to supply any public water system of any contaminant, and if the presence
of such contaminant may result in such system's not complying with
any national primary drinking water regulation or may otherwise adversely
affect the health of persons.
(b) Injection pressure at the wellhead shall not exceed
a maximum which shall be calculated so as to assure the pressure in
the injection zone does not cause movement of fluid out of the injection
zone.
(c) The owner or operator of an ASR injection well
that has ceased operations for more than two years shall notify the
executive director 30 days prior to resuming operation of the well.
(d) The owner or operator shall maintain the mechanical
integrity of all wells operated under this section.
(e) The quality of the water injected at an ASR project
must meet the requirements in §331.186(a)(1) of this title (relating
to Additional Requirements). Water recovered from an ASR project that
is provided to a public water system is subject to all applicable
requirements, maximum contaminant levels, and treatment techniques
under Chapter 290 of this title (relating to Public Drinking Water).
(f) All ASR injection and ASR production wells must
be installed with a flow meter for measuring the volume of water injected
and the volume of the water recovered.
(g) This subsection only applies to an ASR project
that is located within the jurisdiction of a groundwater conservation
district or other special-purpose district with the authority to regulate
the withdrawal of groundwater.
(1) An authorization or permit issued under this chapter
may not authorize a volume of water to be recovered that exceeds the
volume of water that is injected or the volume of injected water that
the commission determines can be recovered, whichever is less; and
(2) The requirements of Texas Water Code, Chapter 36,
Subchapter N apply to the volume of water recovered from an ASR project
that exceeds the volume of water the commission determines can be
recovered, and otherwise as applicable.
