Revision <br />February 1982 <br />2.05.5 Post-mining Land Uses <br />• (2} Underground Mining Activities <br />Post-mining land use will not be altered from current use <br />2.05.6 Mitigation of Surface Coal Mining Operation Impacts <br />(1) Air Pollution Control Plan <br />Emission permit applications and copies of permits are included in <br />Appendix X,.12. Appendix XVI includes additional information on air pollu- <br />• tion control. Exhibits 2.05.6-A and 2.05.6-B indicate far_ilities on the <br />East and West Portal areas which require emission permits. Particulate air <br />quality in the study area ranges from 20 to 132 micrograms per cubic meter <br />(ug/m3) annual geometric mean as recorded at sixteen state, municipal, and <br />privately operated particulate sampling sites. In undeveloped sections, <br />particulate concentrations range from 20 to 40 ug/m3. <br />The available particulate sampling data which best represent existing <br />particulate air quality at the Hawk's Nest Mine are provided by a privately <br />operated sampler located on the Atlantic Richfield Company proposed site <br />for the Mt. Gunnison Mine. The annual geometric mean concentrations <br />recorded on the sampling site in 1977 were 28 ug/m3, with first and second <br />maximum 24-hour concentrations of 95 and 69 ug/m3, respectively. <br />• There have been no measurements of carbon monoxide, hydrocarbon, <br />nitrogen oxides, sulfur dioxide, or other gaseous pollutants near the <br />2.05-56' <br />
