Authority to Construct / Permit to Operate

Any person or facility that puts in place, builds, erects, installs, modifies, modernizes, alters or replaces any article, machine, equipment or other contrivance, the use of which may cause, reduce or control the emission of air contaminants, shall first secure written authorization from the District in the form of an Authority to Construct, unless the source is specifically excluded or exempt from permit requirements. The District’s permit process is a pre-construction review and approval process. The District’s review is conducted after the equipment is designed, but before it is installed. This is because it is less costly and more efficient to fix a non-complying design than to retrofit or replace non-complying equipment that has already been installed. The pre-construction review for new and modified sources applies to both stationary and portable sources of emissions that do not qualify for a permit exemption.
