TRANSIT MIX AGGREGATES <br />January 9, 2009 <br />Mr. Dustan Crelly <br />United States Department of Labor <br />Mine Safety Health Administration <br />Rocky Mountain District <br />PO Box 25367 DFC <br />Denver, CO. 25367-0367 <br />Re: Pikeview Quarry <br />Dear Dustan, <br />I-A- 1 Vt The purpose of this letter is to address a couple of items. First, to update MSHA as to what has occurred <br />since the slide occurred on the 2"d of December. As you can imagine it has been somewhat overwhelming. <br />We are currently evaluating the best long term monitoring method to be used at the quarry. Yenter <br />Companies has provided us with a proposal and we had Dr. Ugur Ozbay, Department Chair, Mine <br />Engineering, Colorado School of Mines and Mr. S. Patel, Old Castle Materials, down to the site for their <br />thoughts as to the best methods. Mr. Patel is a graduate mine engineer from the South Dakota School of <br />Mines and has spent the last 25 years mining a limestone quarry in Rapid City, South Dakota. Mr. Patel <br />and our president were class mates and Jerry felt his hands on experience would serve us well. Currently a <br />total robotic station with the ability to laser scan the quarry face on a daily basis seems most promising. <br />It seemed to be the general consensus of people like Paul Donahue and Eric Gottheld from MSHA and <br />Berhan Keffelew, Reclamation, Mining and Safety along with Mark Heifner, Southwest Ecological, that <br />we ought to take 30 days and just observe what is going on with the site. At their recommendation we also <br />set up some basic monitoring devices. They are located on three different scarps at the site to help <br />determine if any movement is occurring. These include the most southern scarp, the scarp that crosses the <br />road and one on the north end of the quarry. <br />Between December 2"d, the day of the slide, and December 3`d the scarp on the south end opened up. The <br />pictures on the enclosed CD will show the southern scarp. Directly adjacent to the slide we have <br />experienced some rock falling. This appears to be more associated with gravity and conditions than <br />anything. What I mean is we have had several snows on the mountain and successive thawing. At the edge <br />of the slide on some of the vertical surfaces lose material has fallen. On the north end of the quarry we are <br />seeing no movement. As you can see the north end did not experience the slide to the extent of the south <br />and middle peaks. <br />The second part of this letter is to propose a couple of items. We would like to be able to open the existing <br />road that serviced the bench that the drill is located on. Yenter Companies have been unable to remove the <br />drill during this ordeal. The drill is depicted by the orange circle between the green bench lines on the <br />photos. A road already exists and was bermed closed after the slide. This is the road that the drill used to <br />enter the area. We would also like to be able to remove the two pieces of equipment located south of the <br />drill. We would propose doing this at the same time Yenter removes the drill so that all monitoring <br />equipment and personnel would be in place. There is an existing pile of rubbled material on the east side of <br />the lowest bench. This material can be flattened enough without disturbing any of the material at the toe of <br />the slide to allow for the equipment to access the existing haul road. <br />Third, I would like to ask that we be allowed to process material that is not in an area affected by the slide. <br />The area is depicted by the blue rectangle on the photo along with an existing stockpile area. This area is a <br />haul road that facilitates our off road trucks getting to the feed hopper. We would reconfigure our haul <br />route to the east of the existing haul road and mine the road from a southeast to northwest direction. This <br />Castle Concrete Div.
