Construction. The owner of a proposed injection well or series of
injection wells shall provide the Director with such information he deems
necessary for evaluation of the impact of such injection on the geothermal
reservoir and other natural resources. Such information shall include existing
reservoir conditions, method of injection, source of injection fluid, estimates
of daily amount of material medium to be injected, zones or formations
affected, and analysis of fluid to be injected and of the fluid from the
intended zone of the injection. Such information shall be on a form approved or
provided by the Director. (3-30-23)

Surveillance. (3-30-23)
a. When an owner proposes to drill or modify
an injection well or convert a producing or idle well to an injection well, he
shall be required to demonstrate to the Director by means of a test that the
casing has complete integrity. This test shall be conducted in a method
approved by the Director. (3-30-23)
b. To establish the integrity of the annular
cement above the shoe of the casing, the owner shall make sufficient surveys
within thirty (30) days after injection is started into a well to prove that
all the injected fluid is confined to the intended zone of injection.
Thereafter, such surveys shall be made at least every two (2) years or more
often if necessary. The Director shall be notified forty-eight (48) hours in
advance of such surveys in order that a representative may be present if deemed
necessary. If in the Director's opinion such tests are not necessary, he may
grant a waiver excepting the operator from such tests. (3-30-23)
c. Department personnel may inspect the well
site periodically after the well has been placed on injection. The Director may
notify the operator or owner if any remediation work is necessary. Any
remediation work must be performed within ninety (90) days of notification by
the Director. The Director may rescind approval of the injection well for
failure to perform necessary work. (3-30-23)
