Part 70 (Title V) Permits

Title V of the 1990 Clean Air Act Amendments required EPA to promulgate regulations setting forth provisions under which States would develop operating permit programs and submit them to EPA for approval.  These regulations are codified under 40 CFR part 70; hence, operating permits are often referred to as Title V permits or Part 70 permits.  EPA has fully approved (FR Notice) LDEQ’s Part 70 Operating Permits Program.

Part 70, or Title V, permits combine all enforceable requirements, including emissions limits, monitoring, recordkeeping, and reporting provisions, into one document.  Owners of sources with operating permits must certify that the source is in compliance each year, and the permits must be renewed every 5 years.  Each proposed initial Part 70 permit, renewal, and significant modification is subject to a 30-day public comment period, with an opportunity for a hearing, and a 45-day EPA review period.
