The District permits stationary sources in a 2-step permit process. In the first step, a source applies for Authority to Construct (ATC) permit with temporary operation. This allows a source to modify existing equipment or construct/install new equipment and to operate for up to 12 months. Once construction is complete, the District inspects the site and reviews performance for compliance with applicable air quality requirements. Once compliance is verified, the District will issue the second permit, which is an ongoing Permit to Operate (PTO).
The District’s review and permitting process is described in District regulation R1-2-200. Facilities pay an application fee and an annual operation fee, as identified in District regulation R1-3-310. CARB provides a District rule index and search tool.
