The Mechanical Integrity Assessment (MIA) is a regulatory-based process used to inspect, assess and record quarterly well integrity data for operating oil and gas wells. This quarterly inspection is required by regulation under 25 Pa. Code § 78.88, Mechanical Integrity of Operating Wells. Note that this requirement does not apply to underground gas storage wells, wells that have been granted inactive status, and those regulated under the EPA’s Underground Injection Control Program; monitoring and assessment of those wells is addressed under other sections of Chapter 78.
Annual reports for wells included under the MIA requirement must be submitted to the Department by no later than February 15th of the year following the inspections.
