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 to obtain a Title V Operating Permit, which consolidates all air pollution control approvals, permits and requirements into a single enforceable document. In Massachusetts, the Department of Environmental Protection (MassDEP) is the issuing authority.
