In February 2013, we reported that the Ohio Environmental Protection Agency (Ohio EPA) had issued proposed revisions to its Model General Permit for oil and gas well-site production operations. On April 4, Ohio EPA announced that it had finalized those revisions. The revisions bring the Model General Permits up-to-date with changes in the law since Ohio EPA originally issued the permits and make other changes to respond to industry comments. The revisions also include revised leak detection and repair requirements, which have been the subject of much recent discussion.

Ohio law generally requires each new source of air pollution to obtain a pre-construction permit from Ohio EPA’s Division of Air Pollution Control before “begin[ning] actual construction, erect[ing], locat[ing] or affix[ing] [the] air contaminant source.” Ohio law also requires sources of air pollution to obtain operating permits. Larger sources typically obtain permits-to-install (PTIs) and “Title V” operating permits; smaller sources typically obtain combined permits-to-install and operate (PTIOs). Ohio EPA may also develop Model General Permits — model PTIs and PTIOs — for categories of sources. Sources may choose to apply for regular PTIs or PTIOs if they like, but Model General Permits can be obtained more quickly, because, as Ohio EPA has explained, “all the terms and conditions of the permit have been developed in advance.”
