Each facility that is a major source of air pollution, has the potential to emit specific pollutants above a certain threshold, or falls into a specific category is required by the federal Clean Air Act (CAA) to obtain a Title V Operating Permit , which consolidates all air pollution control approvals, permits and requirements into a single enforceable document.  Most Operating Permits are issued by state permitting authorities.
