Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Surveillance of
					 waste water disposal or injection projects is necessary on a continuing basis
					 to establish to the satisfaction of the Supervisor that all water is confined
					 to the intended zone of injection.
(b) When an operator proposes to drill an
					 injection well, convert a producing or idle well to an injection well, or
					 rework an injection well and return it to injection service, the operator shall
					 be required to demonstrate complete casing integrity to the Division by means
					 of a specific test.
(c) To
					 establish the integrity of the casing and the annular cement above the shoe of
					 the casing, within 30 days after injection is started into a well, the operator
					 shall make sufficient surveys to demonstrate that all the injected fluid is
					 confined to the intended zone of injection. Thereafter, such surveys shall be
					 made at least every two years, or more often if ordered by the Supervisor or
					 his or her representative. All such surveys shall be witnessed by a Division
					 engineer.
(d) After the well has
					 been placed on injection, a Division inspector shall visit the well site
					 periodically. At these times, surface conditions shall be noted and, if any
					 unsatisfactory conditions exist, the operator shall be notified of required
					 remedial work. If this required work is not performed within 90 days, the
					 approval issued by the Division shall be rescinded. The Supervisor may order
					 that the repair work be done immediately if it is determined that damage is
					 occurring at a rapid rate.
(e)
					 Injection pressures shall be recorded and compared with the pressures reported
					 on the monthly injection reports. Any discrepancies shall be rectified
					 immediately by the operator. A graph of pressures and rates versus time shall
					 be maintained by the operator. Reasons for anomalies shall be promptly
					 ascertained. If these reasons are such that it appears damage is being done,
					 approval by the Division may be rescinded, and injection shall cease.
(f) When an injection well has been idle for
					 two years, the Division may inform the operator, by letter, that approval for
					 use of the well for injection purposes is rescinded. If the operator intends to
					 reclaim the well for injection purposes, a Rework/Supplementary Notice shall be
					 filed proposing to demonstrate by specified tests that the injected fluid will
					 be confined to the intended zone of injection.
