Title V Permits

Title V operating permits are legally enforceable documents issued to air pollution sources after the source has begun to operate. Most Title V permits are issued by state, local, and tribal permitting authorities. However, EPA also issues Title V permits to some sources. EPA-issued Title V permits are sometimes called “Part 71 permits” because the regulations that establish the standards for them are found in the Code of Federal Regulations at 40 CFR Part 71.”

The Title V program provides for public participation in the permitting process. The public generally has 30 days to comment on all draft Title V operating permits. For all permits issued by a state or local permitting authority, EPA also has a 45-day review period, which may or may not run concurrently with the public comment period.
