The source is located approximately 3 miles north of Starvation Reservoir at UTM (Universal Transverse Mercator) coordinates of 548,490 meters easting and 4,455,071 meters northing (Datum NAD 83, Zone 12) in Duchesne County, Utah. 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, Mountains West Ranches is not required to obtain an approval order under R307-401 for the Duchesne Gravel Pit. 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.
