Mining is proceeding eastward into the stripped land. It <br />appears that no additional land will need to be stripped during the next year. <br />The installation of the washing system was completed and has added greatly to the functional <br />capability of the operation to produce a wider variety of products. At this time it is not known whether <br />this will accelerate the operation, but it appears that some increase in the rate of mining will probably <br />occur as more demand for washed products, in addition to unwashed products, increases. <br />Annual Report Maps: The enclosed maps show the primary areas of disturbance and the type of <br />disturbance occurring in each area. The disturbance zones shown on the map have changed somewhat in <br />their location and extent in comparison to previous maps. This change is the resul[ of new aerial <br />photography (taken on December 12, 1999) which allowed for a much more accurate portrayal of the <br />disturbance locations. The amount of change in location and definition is not great, but the current <br />maps reflect an updated portrayal of the operation zones. <br />Affected Lands: The amount of affected land has not increased significantly in the last year. The same <br />processes of operating the pit are being used as has been used in the past. The isolated stockpiles in the <br />revegetated land in the northeastern corner of the site were removed. This created a fresh disturbance on <br />the bottom of this basin, but because the land is essentially flat where the disturbance was created no <br />additional erosion hazard was created. This removal will allow bringing this land to completion in the <br />near future. The use of long supply conveyors to carry material from the mining area to the plant helps <br />to extend the amount of time until the plant will need to be moved. The scale was moved from the <br />extreme northeastern corner of the site to the location shown on the map and within the operation. <br />Revegetation: The site is stable and is not subject to erosion. <br />Expected Activity (2000): Mining will proceed eastward into the stripped land. No additional <br />stripping is expected to occur, but with the very active construction market there is a possibility that <br />additional stripping will occur prior to the end of the next permit year. <br />Centennial Materials 1999 Annual Report M-82-155 Fountain Pit Page 1 of 2 <br />
