Exemptions

In general, stationary sources of air pollution require a permit from the District. Prior to installing or modifying a source of emissions, the owner/operator is required to submit a permit application and receive District approval. The District approves permits in a two-step process. The first step is the Authority to Construct (A/C), which is the District's permission for the owner/operator to install the equipment approved in the permit application. Prior to starting up a source, the owner/operator notifies the District of impending operation. If the source was installed in accordance with the A/C, the District will issue a Permit to Operate (P/O). For routine sources, the District may condense the process into a single step and issue a P/O directly, without first issuing an A/C.

Certain sources of emissions are exempt from District permit requirements. These sources are listed in Sections 103 through 128 of Regulation 2, Rule 1 (123 k PDF, 35 pgs). Some sources are exempt because the District is prohibited from requiring a permit by the California Health & Safety Code. Other sources are exempt because the District considers them to be insignificant sources of air pollution.
