R 324.808 Class II well operational testing requirements.

Rule 808. (1) A permittee of a Class II well shall provide for a pressure test that meets the requirement of subrule (2) of this rule, by a qualified person, to determine the mechanical integrity of the tubing, casing, and packer. (2) The annulus between the innermost casing and the tubing above the packer shall be tested at least once each 5 years at a pressure of not less than 300 psig. A satisfactory test shall have a pressure change of not more than 5% over a period of 30 minutes. The difference in pressure between the testing pressure and the tubing pressure shall not be less than 100 psig at the time of the test. At least 5 days before the test, the permittee shall notify the supervisor or authorized representative of the supervisor of the date and time of the test. This subrule applies to all Class II wells, including those with approved temporary abandonment status. (3) Within 14 days after the test, the permittee shall, on a form prescribed by the supervisor, submit a report of each mechanical integrity test to the supervisor or authorized representative of the supervisor. The report shall contain supporting data including, but not limited to, gauge calibration data, pressure recordings and charts, tubing size, packer type, and packer depth. Prior to an 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 that the permittee has demonstrated the well has mechanical integrity. (4) For a Class II well that has not been utilized for its intended purpose for a period of greater than 2 years, the permittee shall, prior to resuming injection, demonstrate mechanical integrity for the well and receive authorization to resume injection from the supervisor or authorized representative of the supervisor.
