Subchapter 61-87.9 - Mechanical Integrity Requirements for Class II and III Wells

A. An injection well will be considered to have mechanical integrity if:

(1) There is no measurable leak in the casing, tubing or packer; and,

(2) There is no measurable fluid movement into an underground source of drinking water through vertical channels adjacent to the injection well bore which would result in deterioration of the water quality in zones above or below the injection zone.

B. The method used to determine the absence of any measurable leaks in the casing, tubing or packer shall be conducted as follows:

(1) Monitoring of the annulus pressure; or,

(2) A pressure test with liquid or gas.

C. The method used to determine the absence of any measurable fluid movement into underground sources of drinking water shall be the results of a temperature or noise log.

D. In conducting and evaluating the tests for mechanical integrity, the owner or operator and the Department shall apply methods and standards generally accepted in the industry. When the owner or operator reports the results of mechanical integrity tests to the Department, the owner or operator shall include a description of the test(s) and the method(s) used. In making the evaluation, the Department shall review monitoring and other test data submitted since the previous evaluation.
