1 Number includes employees working at both King Mine I and King Mine II.
Z Truck trips limited to six days per week by LPC RIA.
From year to year, actual coal production would be based on several assumptions, foremost, that coal
markets are favorable and that GCCE has buyers. Another factor potentially affecting production levels
would be the consistency of coal quality present within the new lease.
Workforce - As of December 7, 2017, there were approximately 66 hourly employees, 12 hourly
contractors, and 14 salaried employees working at the King II Mine.
Relationship to Existing Mining Operations and Facilities -The unleased federal coal reserves comprise
an approximate 2,462-acre block of coal north of the northern limits of GCCE's existing King II Mine
(Appendix A, Figure 1-2). In addition, about 204 acres of non-federal coal would be mined beneath about
479 acres of UMU surface. Surface effects on approximately 366 acres of UMU Tribe owned surface
above federal coal in the LBA and above three isolated private surface areas would be regulated by OSMRE
under a memorandum of understanding with the CDRMS. Section 2.2.3 above provides additional details
of the relationship of the Proposed Action to the existing mining operations and facilities.
Intended Use of the Coal-The coal from the King II Mine is favored for its high heating value (12,300 BTU
per pound) and its low sulfur, ash, and alkali content. It is sold off-site in the southwest U.S. and Mexico
and used in the manufacturing of Portland cement in coal-fired cement kilns.There are also small volume
sales to regional steam-powered railroads and to a local concessionaire for home heating.
