i <br />5.3.3 Mine Facilities <br />The only building on the site which is not mobile is the <br />shop/office building located adjacent to the county road. The <br />only other building associated with the m;n;nq are the explosive <br />storage structures. These structures are mobile trailers that <br />are used for storage of the blasting materials. The locations <br />of these strictures are presented on Map V-1. <br />The shop/office building is constructed of metal (shop <br />area) and brick (office area). The building has been in existence <br />since 1977 when operations were first initiated. The other <br />structures are completely mobile and can be easily moved around <br />the site. <br />The only structures at the mine for which specific design <br />• criteria exist are the haulsoads and sediment control system. The <br />design of the ponds for Section 22 is currently being reviewed <br />as part of the amendment to ~rmit Dhm~ber 79-53. The locations <br />of all oongonents of the sediment control are shown on the <br />~rlimant Control Map. Also, the design of each of the catq~onents <br />of the sediment control system is presented in FS~hibit V-3. <br />The haulroads currently servicing pits 1 and 2 are pre- <br />existing structures. The haul for pit 1 will be left as an access <br />road upon completion of mining in this area. It is anticipated <br />that mining >n pit 1 will be cca~leted by mid March, as plans to <br />mine cuts 3 4, and 5 have been abandoned due to coal quality <br />problems. The existing haulroads will be monitored by mine personnel <br />to ensure canpliance with the applicable performance standards. <br />Additionally, the life of these structures is relatively short and <br />V-19 <br />
