§146.89. Mechanical integrity. — Inbound Citations

(1) The owner or operator of a Class I, II, III or VI well permitted under this part shall establish mechanical integrity prior to commencing injection or on a schedule determined by the Director. Thereafter the owner or operator of Class I, II, and III wells must maintain mechanical integrity as defined in § 146.8 of this chapter and the owner or operator of Class VI wells must maintain mechanical integrity as defined in § 146.89 of this chapter. For EPA-administered programs, the Regional Administrator may require by written notice that the owner or operator comply with a schedule describing when mechanical integrity demonstrations shall be made.

(8) A permit for any Class I, II, III or VI well or injection project which lacks mechanical integrity 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 under § 146.8, or § 146.89 of this chapter for Class VI, that the well has mechanical integrity.

(3) A description of how the Director will implement the mechanical integrity testing requirements of § 146.8 of this chapter, or, for Class VI wells, the mechanical integrity testing requirements of § 146.89 of this chapter, including the frequency of testing that will be required and the number of tests that will be reviewed by the Director each year;

(8) A demonstration of mechanical integrity pursuant to § 146.89;

(2) Appropriate testing methods to ensure external mechanical integrity as specified in § 146.89;
