The source is located approximately 3/4 miles northeast of Bluff at UTM (Universal Transverse Mercator) coordinates 629,090 meters Easting and 4,128,285 meters Northing (Datum NAD 83, Zone 12) in San Juan County. According to your application, onsite equipment includes: one (1) 300 ton per hour jaw crusher, diesel- powered by a Tier 4f ,381 hp engine; one (1) 300 ton per hour, electric cone crusher; four (4) electric stacker belts; one (1) stacker belt, diesel- powered by a 50 hp engine, and; one (1) diesel-fired, Tier 4f, 776 hp generator engine. According to your application, each piece of equipment runs a maximum of approximately 1,000 hours, annually. 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. Please note that the small source exemption is only valid for the above-reference location. Harward and Rees shall notify the DAQ prior to moving to a new location. 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, the Harward and Rees Crow's Nest Pit 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.
