R 324.811 Loss of mechanical integrity.

Rule 811. (1) A permittee of an injection well shall notify the supervisor or authorized representative of the supervisor of any pressure test failure, significant pressure changes, or other evidence of a leak in an injection well, within 24 hours of the pressure test failure, significant pressure changes, or other evidence of a leak. For other evidence of a leak received via logging, the notification shall occur within five working days after the operator first determines that the condition exists from reading the log data, but not later than 10 working days after the day the operator receives the log data. If there is evidence that indicates an injection well is not, or may not be, directing the injected fluid into the permitted injection interval, a permittee of an injection well shall immediately cease injection. (2) A permittee shall submit written notice of the pressure test failure, significant pressure changes, or other evidence of a leak to the supervisor or authorized representative of the supervisor within 5 days of the occurrence, or within 10 days of receiving well logging data, on a form prescribed by the supervisor. If injection has ceased pursuant to subrule (1) of this rule, then a permittee shall not resume injection until the permittee has tested or repaired the well, or both. If the repair requires a change of well status pursuant to R 324.511, or a permit modification, then a plan shall be submitted to, and approved by, the supervisor or authorized representative of the supervisor. The repair or modification plan must demonstrate protection of any underground sources of drinking water. (3) Before resuming injection, a permittee must demonstrate the well has mechanical integrity and receive an authorization to inject. Verbal authorization from the supervisor or authorized representative of the supervisor is acceptable to commence injection. Written authorization to inject from the supervisor or authorized representative will be issued within 7 days of verbal authorization. Prior to issuance of an authorization to inject, the supervisor or authorized representative shall have witnessed the test or received the test data, reviewed the test data, and determined the permittee has demonstrated that the well has mechanical integrity.
