This is done utilizing the services of 30 ton trucks provided by three major and several <br />independent operators. These trucks are operated by a force of approximately 28 drivers. Coal <br />is hauled travelling from County Road 120 east of the King Coal mine site and Colorado State <br />Highway 140 south of Hay Gulch on to regional markets. The mine also supplies coal for <br />residential heating to local customers who pick it up in their own trucks or have it delivered to <br />their homes. <br />II. DESCRIPTION OF THE ALTERNATIVES <br />Alternative 1 -Proposed Action <br />The proposed action is to modify coal lease COC-60941. This modification contains <br />• approximately 160.00 acres of coal bed 1 reserves. The estimated minable coal reserves for coal <br />bed 1 within the lease modification is approximately 1,486,015 tons with approximately 847,000 <br />tons estimated as being recoverable. This proposed lease modification area would be mined as <br />an extension of the existing King Coal mine. At a production rate of approximately 300,000 <br />tons/yeaz, the mine would have recoverable coal resources for approximately 4 more years. If <br />granted the proposed lease modification, the life of the mine would be extended by approximately <br />2.8 years. <br />The tract is adjacent south and southeast ofthe current COC-60941 lease(map 2). Federal leases <br />COC-29125 and COC-49465 (existing Federal leases held by National King Coal) lie to the north <br />of the lease application area. The applicant proposes to enter the proposed modification area via <br />existing underground workings from the north along the north boundary and project the <br />underground mine workings to the southwest using the room-and-pillar method of mining. The <br />mining plan consists of development of main and submain entries off of which panels are driven <br />for pillaz extraction. The pillars in panels will be squaze or rectangular in shape and aze typically <br />developed on 50 by 75-foot centers with the entries 16-18 feet wide. This allows for better <br />ventilation and systematic pillar recovery. <br />The existing surface facilities would be used to support continued mining activity at the King Coal <br />mine. No new surface disturbance would occur as a result of the lease modification. It is <br />• 4 <br />
