through. Therefore Cemex owns this property, however it has technically been removed from the permit boundary. Cemex received approval for the Dowe Flats Estates Subdivision Exemption Case SE-03-01 from Boulder County on April 15, 2004 through Resolution 2003-63 and the plat has been recorded with the Boulder County Clerk and Recorder at Reception No. 25577189. The subdivision can not be developed until after mining and reclamation are complete and the two roads shown and labeled on Figure 1 will remain after mining and reclamation as access to the approved subdivision. Therefore, these roads do not need to be part of the financial warranty for reclamation. • Maximum Allowable Acreage of Disturbance at Any One Time Durinq Mining Before Reclamation Must Begin The current permit contains a provision that unreclaimed mining disturbance shall not exceed 95 acres. We have calculated the current unreclaimed mining disturbance at approximately 91 acres. We would like to clarify that the 95-acre disturbance maximum does not include other affected lands, such as the access road, trailers and maintenance shop, stockpiles, etc. It should be noted that Cemex has revegetated approximately 148 acres of previously disturbed land, including mining and stockpile areas (see Figure 2 for a map depicting the reclaimed and unreclaimed land). Cemex is requesting, through this Technical Revision, an increase in the maximum allowable acreage of unreclaimed mine disturbance from 95 acres to 105 acres. The current unreclaimed mine disturbance is shown on Figure 2. • Total Allowed Affected Acres for the Life of the Mine Affected land includes mining and reclamation areas, haul and access roads, the crusher and conveyor areas, trailers and maintenance shop, waste rock and topsoil stockpile areas and the fuel island. For clarification, the 385 acre limitation on mine disturbance is not the same as total affected land. The 385 acres is the actual area to be mined. The total allowed affected land for the life of the mine will be the 385 acre ultimate mine perimeter (inside of which all mining will occur) plus the acreage of all the other categories of affected land mentioned above. Subtracted from this category will be the main access road from State Highway 66 and the road entering the site from County Road 49. These roads will remain for access to the Dowe Flats Estate Subdivision. Cemex, Inc. - Dowe Flats Limestone Mine Page 2 2009 TR-02
