1 The permitted emissions include both point and fugitive sources and annual emissions that were derived from the
CDPHE permit that allows 1.3 mt production as shown in Table 2.2-9 in the TRR.
2GHG 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.
Indirect Effects
Indirect air emissions from the Proposed Action were estimated for activities that are reasonably
foreseeable and include: coal transport (where the destination is within the USA and the quantity of
delivered coal is known), mine worker commutes, and downstream coal combustion. Specific
transportation emissions are located in Table 3-6 of the 2017 Lease Modification EA (BLM and OSMRE
2017)and under the Proposed Action would continue for the next 22 years.
On average, approximately 448,785 tpy is transported by truck to the rail terminal in Gallup, New Mexico
for delivery to GCC plants in Mexico and to variable cement plant buyers in the Southwest depending on
markets, alternative fuels, and coal supply. 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 shipped (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 GCC 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).
