Additional considerations for SO2 RACT determinations. The coal-fired power plants rely on the Usibelli Coal Mine for their supply of coal, which is 

mine in Alaska. Given the unique geography of Alaska and the lack of any bulk commodity marine import terminals, importing coal of a different tyeconomically infeasible. The low sulfur coal noted above, sourced from the Usibelli mine, is the only reasonably available supply of fuel for the coa

Fairbanks North Star Borough. The sulfur content of Usibelli run-of-mine coal ranges from 0.12% to 0.34% with an average of 0.2%. Similarly, the supply of fuel for the oil-fired power plants is also limited. Crude oil is distributed to Fairbanks via the trans-Alaska oil pipeline system

Hills North Pole Refinery has limited the supply of fuel oils to the Petro Star North Pole Refinery, which produces two type of oil products, No. 1 disdistillate fuel oil. The No. 2 distillate fuel produced by the Petro Star North Pole Refinery is the lowest-sulfur, reasonably available supply of fuel for 

in the nonattainment area. No. 2 distillate fuel oil produced by the Petro Star North Pole Refinery ranges from 0.39% to 0.44%. Note that the No. 2 

at the two refineries on the Kenai Peninsula have a lower sulfur content than that produced in Fairbanks as a result of the different crude oil feeds

oil from the Kenai refineries would result in lower SO2 emissions.
