Current through Supplement No. 393, July, 2024

Section 33.1-25-01-13 - Mechanical integrity

1. A permit for any class I well shall include, and for any class V well may include, a condition prohibiting injection operations until the permittee shows to the satisfaction of the director that the well has mechanical integrity.

2. An injection well has mechanical integrity if:

a. There is no significant leak in the casing, tubing, or packer; and

b. There is no significant fluid movement into an underground source of drinking water through vertical channels adjacent to the injection well bore.

3. The mechanical integrity of a class I nonhazardous waste well must be demonstrated using the methods listed under title 40 CFR part 146, section 146.8(b), (c), (d), and (e). The director may also allow the use of a radioactive tracer survey (timed run method) for detecting leaks in the tubing, casing, or packer and for demonstrating the absence of fluid movement behind the casing (where the injection zone immediately underlies the lowermost underground source of drinking water on a case-by-case basis).

4. The mechanical integrity of a class I hazardous waste iniection as defined by title 40 CFR part 146, section 146.8 must be demonstrated as established by title 40 CFR part 146, section 146.68(d).

5. The mechanical integrity of a class I nonhazardous waste injection well must be demonstrated at least once every five years and whenever there has been a well workover.
