• 4.7 AIR POLLUTION CONTROL PLAN <br />Trapper Mine holds four separate emissions permits issued by the Colorado Air Pollution Control Division <br />(APCD) for various mining activities (Section 2.2). As a condition for the emission permit for mining <br />(C-11, 253(1)), Trapper Mine did operate one hi-volume air sampler to monitor total suspended particu- <br />late (rSP) levels in accordance with APCD requirements. Two other monitoring stations, one maintained <br />by Cyprus Empire Corporation and the other by TriState Generation & Transmission Association, Inc. <br />are near the proposed permit area. While Trapper does not maintain or operate these two stations, the <br />resulting data are available to the APCD for a total evaluation of TSP levels in the area. Locations of <br />these air samplers are illustrated in Map M-15. <br />4.7.1 Monitoring Program <br />One air monitoring station, P-5, was maintained by Trapper Mine personnel as required by the APCD. <br />The station was monitored in accordance with APCD standards of one sample per week of 24 hour <br />duration. A Misco 680 high-volume air sampler was used to obtain total suspended particulate data with <br />the results being tabulated by Trapper personnel. On June 30, 1988 the APCD terminated the require- <br />ment that Trapper continue this ambient particulate air monitoring program. Figure 4.7-t presents the <br />letter of authorization from APCD. <br />• <br />4.7.2 Fugitive Dust Control Measures <br />P,Aining and associated activities are sources of fugitive dust emissions. Fugitive dust emission control <br />methods used at Trapper Mine are described in this section. <br />P2-3 __ <br />;~GVISIOt~ P°r;. <br />a•17o / <br />~, x_93 <br />..,AT6 <br />~~ <br />-_ _ .... <br />
