Headings and quoted sections on this page are copied from the eCFR text of Subpart LLL without changes. AirPermitHub checks eCFR every week and reviews any change before publishing it, so this page can trail eCFR by a few days. eCFR is maintained by the Office of the Federal Register and the Government Publishing Office. It is not an official legal edition of the CFR, and it does not show how an agency has applied the rule in a permit.
Where to look in Subpart LLL
Sections sorted by the words in their eCFR headings. Read the full section before relying on it; requirements often sit in more than one place.
