Section R. 324.806 - Testing and authorization to inject before operation of Class II injection wells

Rule 806.

(1) Before injecting fluid into a new Class II well, a permittee of a well shall provide for a test of the annulus between the innermost casing and the tubing above the packer. The test shall be conducted by a qualified person and the test shall be at a pressure of not less than 300 psig. The difference in pressure between the testing pressure and the tubing pressure shall be not less than 100 psig at the time of the test. A satisfactory test shall have a pressure change of not more than 5% over a period of 30 minutes.
(2) A permittee of a well shall notify the supervisor or authorized representative of the supervisor at least 5 days in advance of the date and time of the test.
(3) Within 14 days of completion of the test, the permittee shall submit, on a form prescribed by the supervisor, a report of each mechanical integrity test to the supervisor or authorized representative of the supervisor. The report shall contain test supporting data, including, but not limited to, gauge calibration data, pressure recordings and charts, tubing size, packer type, and packer depth. Approval of the test results will be based on witnessing by supervisor or authorized representative of the supervisor, or review and evaluation of test data submitted pursuant to this subrule.
(4) Before the commencement of injection, a permittee shall receive an authorization to inject from the supervisor or authorized representative of the supervisor. Prior to issuance of the authorization to inject, the supervisor or authorized representative shall have witnessed the test or received the test data, reviewed the test data, and determined that the permittee has demonstrated that the well has mechanical integrity. Authorization to inject will be granted only after any applicable well records required by R 324.418 have been received and evaluated by the supervisor or authorized representative of the supervisor. Verbal authorization from the supervisor or authorized representative is acceptable to commence injection. Written authorization to inject from the supervisor or authorized representative will be issued within 7 days of verbal authorization.
(5) Injection wells utilized for gas storage are exempt from this rule.
