<br />5 <br />I. Procedures for Seeking Release of Performance Bond (Rule 3.03.2) <br />The Division finds that, based on the review process history, the requirements for seeking <br />release of performance bonds as set forth in Rule 3.03.2 have been met. Copies of written <br />notices as required by Rule 3.03.2(1)(a) have been submitted to the Division. Proof of <br />publication in accordance with Rule 3.03.2(10)(b) has also been submitted. The current <br />landowners, Mr. Albert Iuppa and Mr. Jim Iuppa, were notified of the bond release <br />inspection. A site inspection was held in accordance with Rule 3.03.2(2). <br />No comments or objections were received within thirty days of the last publication or within <br />thirty days of the completed inspection, as allowed by Rule 3.03.2(4). <br />II. Criteria and Schedule for Release of Performance Bonds. <br />The Raton Creek Mine occupies the same location and utilized some of the portals used <br />by the Animas and Helen Mines. This valley has historically been mined since the late <br />1800's. The Raton Creek Mine had previously been permitted as the Animas/Helen Mines <br />by the previous operator. The "Animas" portals correspond with the No.l portals located <br />at the southeastern portion of the disturbed area. The "Helen" portals correspond with the <br />No. 2 portal area located at the northern portion of the disturbance area. <br />The permit was originally approved to allow a coal waste bank to remain after mining. This <br />waste bank was originally projected to have a volume of approximately 1,300,000 cubic yards <br />of coal refuse material. The plan projected that the waste bank would cover the highwall <br />associated with the No. 2 Portals (Helen Mine). This highwall extended approximately 1300 <br />feet through the north portion of the mine disturbance area. <br />Due to the early closure of the mine, approximately only 294,000 cubic yards of refuse <br />material was actually placed in the waste bank. Energy Fuels Mining Company subsequently <br />revised their plans to utilize approximately 116,300 cubic yards of refuse material to backfill <br />all remaining highwalls at the north portion of the mine area. Energy Fuels redesigned the <br />waste bank to have 3h:ly slopes, lift thickness of 24 inches or less, and a compaction <br />standard of 90% dry density, where 96.4 pounds per cubic foot equaled the maximum dry <br />density value for the refuse material. This design provided for a stability safety factor of 2.5, <br />a 66.7% higher degree of safety than the state regulatory requirement of 1.5 (Rule <br />4.10.4(2)). These designs were approved by the Division on July 8, 1994, in accordance with <br />Rule 4.10.4(3). <br />The highwalls in the vicinity of the No. 2 Portals were backfilled in accordance with Section <br />2.05.4(2)(c) of the approved permit and Rule 4.10.4(3). <br />
