ENVIRONMENTAL ASSESSMENT <br /> The GCC Rio Grande Pueblo Plant(Table 3-3) has a permit (#98PB0893) condition that limits annual firing <br /> fuel (coal and tire derived fuel (TDF))to no more than 198,418 tons on a rolling 12-month basis.The King <br /> II Mine currently supplies 105,000 tons of coal annually(approx. 53 percent by weight)to the facility and <br /> expects this to remain constant going forward. The GCC Rio Grande Tijeras Plant (Table 3-4) has similar <br /> operations to that of the Pueblo facility and is covered under NM Title V permit #532. The permit and <br /> underlying construction permits provide for all the same source requirements (controls and monitoring) <br /> as the Pueblo facility and is publicly available from the Albuquerque Environmental Health Department <br /> for review. Unlike the Pueblo facility the Tijeras kiln is fired entirely on coal (a minor amount of natural <br /> gas is used for startup) and the kilns themselves do not appear to have fuel throughput limits, but rather <br /> performance-based clinker production limits (33.7 tons/hour). <br /> Table 3-3.

A detailed discussion regarding these emissions can <br /> be found in the accompanying TRR(OSMRE and BLM 2019) (Section 2.2.2). <br /> Cumulative Actions and Effects <br /> The cumulative impact assessment for air quality considers air emissions from mine operations and coal <br /> transport when added to other past, present, and reasonably foreseeable future actions.The cumulative <br /> impacts to air quality in the King II Mine area would result primarily from emissions of PM2.5/10 from the <br /> current and future activities occurring within the region such as agriculture, ranching and grazing, and <br /> vehicle traffic. <br /> To examine potential cumulative air quality impacts from activities that it authorizes, BLM initiated the <br /> CARMMS. The study version 2.0 was primarily concerned with assessing statewide impacts of projected <br /> oil and gas development (both federal and fee (i.e., private)) out to year 2025 for three development <br /> scenarios (low, medium, and high), but also included a statewide mining impact assessment.
