Peters 313 Pit Pre-Mining Engineering Evaluation <br /> The Peters 313 pit area currently has slopes ranging as steep as 5:1 and the area is stable. Weld <br /> County plans to mine the pit so all slopes are mined to a 3:1 slope or less. All slopes will be <br /> reclaimed to a 3:1 slope or less. No high wall mining will occur. The minimum offset from any <br /> structure will be 25 feet. In most areas, the distance from the structure to the edge of the pit <br /> will be much greater than 25 feet. <br /> To ensure that no vehicles or equipment travel onto the OneOk Bakken pipeline that runs <br /> north-south along the far west edge of the permit area, Weld County will construct the access <br /> road entirely outside of the 50-foot pipeline easement(25 feet on each side of the pipe), on the <br /> East side. Additionally, Weld County will install a small berm along the western edge of the <br /> access road to prevent vehicles from wandering into the OneOk Bakken easement. <br /> There are four pipelines operated by Tallgrass and Kinder Morgan which will be crossed by the <br /> access road. The access road will be raised to add cover over all of these pipes. No mining will <br /> occur within 200 feet of the pipelines. <br /> A tank battery exists southwest of the site within 200 feet of the permit boundary, but not <br /> within 200 feet of the mineable area.To protect the tank battery, no mining operations will <br /> occur within 200 feet of the tank battery as shown in Exhibits C1 and C2. <br /> Weld County has included evidence of attempts to contact the owners of structures which are <br /> located within 200 feet of the mineable area. Copies of the structures agreements which have <br /> been signed are included with this application revision. Certified mail receipts for those <br /> structures owners which have not returned the agreement have also been included. Weld <br /> County commits to continuing to obtain structures agreements from those structure owners. <br /> Weld County also commits to compensating all structures owners if damage occurs to their <br /> structures as a result of our mining activity. <br />
