(a) All Class V aquifer recharge (AR) 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 of any contaminant
in underground water which supplies or can reasonably be expected
to supply any public water system, 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 and volume at the wellhead shall
not exceed a maximum which shall be calculated so as to assure the
pressure and volume in the injection zone does not cause movement
of fluid out of the injection zone.
(c) The owner or operator of an AR injection well that
has ceased operations for more than two years shall provide verification
of the well's mechanical integrity and notification of intent to resume
operations to the executive director at least 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 AR injection
well must meet the requirements in §331.267(a)(1) of this title
(relating to Additional Requirements).
(f) All AR injection wells must be installed with a
flow meter for measuring the volume of water injected.
