Attachment 12 page 6 • BUFFALO STONE LLP IMPACT ANALYSIS -EXHIBIT 2 -CONTINUED JiJLY 17, 2007 Impact analysis. In the following analysis we will address the pros and cons of approving this proposed Quarry. The bottom line is that approximately 6, 000 tons of limestone will be used each yeaz from this area. It is important to remember that it will take the same number of truck trips to haul this amount of material no matter where is mined, only the time it takes and the number of trucks needed would change. The longer the haul the more trucks will be needed or the more time will be needed to supply the stone using the same number of trucks. Haul Route impacts: The limestone from this mine would be hauled down County Road 223, a distance of 8 miles to HWY 160, then on to different locations. Due to the low volume of traffic on the county road there will not be much impact on the county roads. Dust: There will be a minimal amount of dust associated with this mine. The only time there will be dust is while getting the dirt off the limestone. In mining operations and all activities that create dust, the idea is to control it since total elimination is not possible. The Colorado Department of Health requires an Air Pollution Emissions Notice permit • (APEN) for all processing equipment that produces more than 70,000 tons/yeaz. An APEN may also be required for a quarry if more than 70,000 tons of rock per yeaz is produced. We aze estimating that no more than 6,000 tons will be produced, so no permit is required. We will use best management practices (BMPs) at all times to control dust emission from the mine. These BMP's included using gravel roadways, watering stockpile area, revegetating topsoil piles that will not be disturbed regulazly and seeding reclaimed azeas during the next planting season or as soon as practical after the seedbed is prepazed. We have the responsibility to control dust on our access and internal mine roads. ADDITIONAL INFORMATION: Water - Since we aze not developing the site, only removing limestone, we do not need water at the site for the normal uses. Drinking water for employees and visitors will be supplied in the form of bottled water or will be brought to the site by our employees. We do not need water for permanent buildings or sanitary facilities (self-contained) so the need for a well permit or water server agreement is unnecessary. Sewer - Sanitary facilities will be provided in the form ofself-contained portable units. There are no permanent structures on the site so it impractical to construct
