The source is located 0.75 Miles East of 325 Landfill Road, in Washington 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 registration assumes the source processes less than 250,000 tons of aggregate material per year and operates the diesel-fired generator engine for less than 700 hours per year. 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, BHI’s Telegraph 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.

In order to achieve 250,000 tons/year at 200,000 tons/hour, the plant would need to operate 1,250 hours per year. The diesel engine's emissions are estimated using 700 hours per year. Can you explain how the aggregate pit operates for 1,250 hours annually when the diesel engine only runs for 700 hours? Does annual production need to be updated to 140,000 tons/year? The SSE registration form lists the operating schedule as 8 hours a day, 5 days a week. This is more than 1,250 hours per year. Please provide clarification on the pit's operating schedule. - Can you provide more information about the 450 hp engine that is being used (spec sheet, date of manufacture, EPA tier, emission rates if known, etc.)?

The remaining hours of production are spent on material that is not processed through the plant, such as boulders, large cobble, and bank run. The operational schedule of 8hrs/5days includes mining/excavation, site maintenance and cleanup, plant maintenance, building feedstock, loading trucks from stockpiles, etc. Basically, the plant and generator do not run for about 3 months out of the year. All of that being said, while gathering data on the diesel engine, I was told that they purchased a new generator for this site (I thought they were using one they already had when I put the data in). The new generator is almost double the size 4/7/25, 11:34 AM State of Utah Mail - Small Source Exemption for BHI's Telegraph Pit https://mail.google.com/mail/u/0/?ik=c52f18613a&view=pt&search=all&permthid=thread-a:r-5159709017314027434&simpl=msg-a:r-68279110866535…1/5 and when I put the info into the spreadsheets it puts the NOx over 5 tons/year. I have talked to them about this and we have decided to lower the production amount per year. I will get the spreadsheets updated and sent over to you first of next week. Sorry for the confusion. I have attached the spec sheet for the new engine. Feel free to reach out if you have any other questions or concerns.

I do not know the emission rates, but I will try to do some more research on it because it may show lower rates than spreadsheet. If that happens to be the case could we use those numbers instead of spreadsheet? Our ultimate goal is to get as much production tonnage as possible without going over the thresholds.

Since the engine is Tier 4 and very new, it should have lower emission rates than what the spreadsheet defaults with. Most manufacturers should be able to provide NOx and CO emission rates and likely VOC and PM as well.

I added the emission standards and it decreased the emissions significantly so I wanted to make sure I used the correct Emission Standards (g/hp-hr) data. I also attached the spec sheet for the diesel engine. Let me know what you think and if it looks good I will get an updated form.

The only thing I would confirm is the horsepower of the engine that the source has purchased. The emission data sheet lists 836 hp and the calculations you have attached use 740 hp.
