Table 2.2-13 outlines the combined direct annual emissions given a coal production rate of 1.3 million tons and total direct Project lifetime emissions from 17 million tons produced.This is derived from a mine life of 22 years with 19 years at the annual production of 800,000 tons and the remaining three at 600,000 tons.

Z GHG emissions are considered longer term pollutants than annually because they tend to stay in the atmosphere for much longer periods of time. Criteria pollutants are assessed on an annual because of shorter averaging period standards.The"N/A"are added to reflect the varying timeframes. 2.2.2.3 Indirect Emissions Indirect air emissions from the Proposed Action were estimated for activities that are reasonably foreseeable and include; coal transport (where a destination within the USA and quantity of delivered coal is known), mine worker commutes, and downstream coal combustion. Downstream Emissions GCCE supplies approximately 193,100 tons of coal to two cement kilns and two narrow gauge railroads directly,while the remainder of the coal is sold (via the Gallup, NM rail terminal)to GCC cement plants in Mexico (240,000 tpy) and to variable cement facilities in Arizona and Texas. Both cement kilns operate under state issued air permits, and both facilities are subject to Title V permitting requirements(i.e.,they are classified as major stationary sources). The GCC Rio Grande Pueblo Plant (Table 2.2-14) has a permit (#98PB0893) condition that limits annual firing fuel (coal and tire derived fuel [TDF])to no more than 198,418 tons on a rolling 12-month basis.The King II Mine currently supplies 105,000 tons of coal annually (approximately 53 percent by weight)to the Dunn Ranch Area LBA and Mining Plan Modification 21 Technical Resources Report
