PLATTE SAND & GRAVEL, LLC <br />AUGUST 17, 2010 <br />PAGE 2 <br />our work around or under their structures. We apologize for not supplying the Division with <br />this document as required. <br />Inspection Topic: General Compliance with Mine Plan <br />Problem: Not following Stipulation #2 of Amendment 01 <br />Attached is the monitoring data we have collected since 2005 regarding the ground water <br />elevations around the Sharkey's Reservoir. The attached map shops the location of the <br />Piezometers from which the data was collected. Over this time we have had 3 different <br />people collecting this data that have left the company. We have had a lot of trouble getting <br />the information together as it was not all in one place. Some is missing but at this time we do <br />not know why, we suspect it was loss or not collected. <br />Inspection Topic: Revegetation <br />Problem: Weed Control. <br />Weed control began the week after the inspection, weather permitting. We have been <br />mowing and spraying as appropriate around the active mining area, plant site and roads. The <br />ranch owners have been doing weed control in the areas not used by Platte Sand & Gravel. <br />The attached pictures show examples of what we have being doing and will continue to do <br />into the future. They show mowed areas, burned area and spray areas where weeds are <br />dying. Approximately 100 hours have been spent no weed control since the inspection. <br />Spraying has taken place over the past 2 weeks, M-F from 7:00 AM to 5:00 PM on the areas <br />away from the water. Standing water makes some areas needing weed control inaccessible <br />and we do not feel spraying near water is ecologically sound. The areas have been sprayed <br />with VB400 mixed with oil according to the manufactures directions. We will continue on <br />weed control throughout the life of the mine. <br />he noted problems and if you have any questions please call me. <br />cc Environment, Inc. <br />Gilcrest Reservoir, LLC. <br />file
