The source is located at 2850 Airport Road, Building D6 Logan, Cache County. DAQ has determined the small source exemption applies to the source, as long as the equipment and associated processes operate as specified in the registration request. The small source exemption does not exempt a source from complying with other applicable federal, state, and local regulations and the current Utah Administrative Code. Based on the emissions that you submitted to DAQ with your registration request, Utah State University - Airport Hangar Space Dynamics Laboratory is not required to obtain an approval order under R307-401. If you change your operation such that there is an increase in emissions, we recommend that you notify us, as an approval order may be required. As authorized by the Utah Legislature, the fee for issuing this small source exemption is a one-time filing fee in addition to the actual time spent by the review engineer and all other staff on the project. Payment should be sent to DAQ upon receipt of the invoice. 195 North 1950 West • Salt Lake City, UT Mailing Address: P.O.
