AIR POLLUTION CONTROL DIVISION PRELIMINARY ANALYSIS PERMIT NUMBER: APPLICANT: 19WE0209F, 19WE0211 DATE: April 3, 2019 Colorado Sand Company LLC ENGINEER: Greg Marcinkowski CP SUPERVISOR: R K Hancock III, PE PROJECT DESCRIPTION The applicant proposes to develop an approximately 10 -acre sand mine, with raw material extraction limited to 235,000 tons per year. The operation will include an APEN/Permit exempt wet screening plant and a 140 ton/hour sand dryer. The length of actual mining and processing of sand is anticipated to last approximately 3 months, with total time the site will be active less than 6 months. SUMMARY OF EMISSIONS (tons/year) AIR POLLUTANT POTENTIAL TO EMIT CONTROLLED EMISSIONS REMARKS NO. 8.6 8.6 PM 900.9 5.7 PM io 884.9 3.4 Source is a synthetic minor PM2.5 878.4 2.4 source for Title V and PSD VOC 1.0 1.0 programs. CO 14.5 14.5 SO2 0.1 0.1 The Division has determined that the above emission source will comply with all applicable regulations and standards, and plans to issue emission permits. Copies of the draft permits are included in the public comment packet. SOURCE CLASSIFICATION The sand mine and dryer have the potential to emit (PTE) a total of 900.8 tons of Particulate Matter (PM) per year. After operational limitations were placed, the PM emissions will not exceed 5.7 tons per year. Because this source has a PTE greater than 250 tons per year of a criteria pollutant, but will control emissions to levels below 250 tons per year, this source is classified as a synthetic minor facility. As a synthetic minor facility, this source is required to undergo a public comment process.

Right now if we equate PM/PM10/PM2.5, the emissions from the dryer/baghouse are 5.7 tons per year as you reported. Adding in the controlled pit emissions brings PM2.5 to 6 tons. The modeling trigger for PM2.5 is 5 tons per year. This is also based on the provided emission factor of 200 lb/hr for the dryer. If you have an. emission factor in lb/ton, we can base the PTE on the 235,000 tons per year instead of 8760 hours. Or if you have the design rate of the dryer in tons/hour, we can derive the emission factor from that. Let me know what you think.

Per your comment about annual production, we equate that to the raw material that will be removed from the ground. Since final product. will vary for every operation, the raw material removal is something we can put a limit on. It looks like for this case we will want to change the requested limit to 235,000 tons per year, but you can leave the finished product hauling at 180,000 tons if that is accurate. I can just make a redline on the application to reflect the change if that's alright. _ Thanks for the information on the screen as well. You may know this but there is an APEN exemption in Reg 3 for wet screening plants that aren't subject to NSPS OOO. This may be applicable if there won't be any crushing happening on the site.

Good afternoon Ms. Campsie, I am reviewing the application for the Keenesburg Site and had a few questions. See below: • The requested annual production is listed as 180,000 tons. This number should be the same as most of your other annual limits. You have indicated 235,000 tons for annual raw material removal, material conveyed, screened, and raw material hauled. Let me know if you would like to change the annual production to match the raw material removal of 235,000. Everything else on the mining APEN looks fine. • For the screen, if there are no spray bars we won't give a control percentage for just moist material. Material coming out at 7.4% moisture won't achieve the same control as spray bars, so we will just assume the screen is uncontrolled. You have reported 2.94, 1.02, and 0.07 tons per year for PM, PM10, and PM2.5, respectively. PM and PM10 look accurate, but I came up with 0.15 tons per year for PM2.5. These values will become the permit limits. • For the dryer, the PTE of 877.31 tons per year of PM will make this a synthetic minor source, and therefore trigger public comment. Once the permit has been drafted, this process takes about 30 days. Also, unless you can verify otherwise, we assume that PM=PM10=PM2.5, so we would carry the PM permit limits to PM10 and 2.5 as well. Please let me know if you have any questions about this.

You have indicated 235,000 tons for annual raw material removal, material conveyed, screened, and raw material hauled. Let me know if you would like to change the annual production to match the raw material removal of 235,000. Everything else on the mining APEN looks fine. I understand the annual production to be of final product sand for sale not the raw material amount. If so, 235,000 in raw material yields approximately 180,000 in product. Let me know what you think. • For the screen, if there are no spray bars we won't give a control percentage for just moist material. Material coming out at 7.4% moisture won't achieve the same control as spray bars, so we will just assume the screen is uncontrolled. You have reported 2.94, 1.02, and 0.07 tons per year for PM, PM10, and PM2.5, respectively. PM and PM10 look accurate, but I came up with 0.15 tons per year for PM2.5. These values will become the permit limits. I am checking on the controls for the screen and will let you know as soon as I hear back. • For the dryer, the PTE of 877.31 tons per year of PM will make this a synthetic minor source, and therefore trigger public comment. Once the permit has been drafted, this process takes about 30 days. Also, unless you can verify otherwise, we assume that PM=PMI0=PM2.5, so we would carry the PM permit limits to PM10 and 2.5 as well. Understood, and carrying PM to PM10 and PM2.5 should be fine.
