Based on the performance of the temporary shaft heaters during winter 2007/2008, TCC determined that additional <br />heat output would be needed, both to prevent icing and to provide an adequate flow of warm ventilation air during <br />• topsoil was temporarily stockpiled adjacent to the pad. Once the system was working, the topsoil was redistributed <br />and seeded with the rangeland seed mixture. A temporary access road was constructed to the drill -site across an <br />undisturbed area. Approximately 28 inches of topsoil was salvaged from the road corridor and temporarily <br />windrowed to the side. After drilling and setting the casing the road was reclaimed by blading the topsoil back over <br />the area, and the area seeded with the rangeland seed mixture. Any future access into the area will be along the <br />existing railroad tracks. Given the limited amount of disturbance and rapid reclamation of the area it is requested <br />that this area be identified as a Small Area Exemption. Therefore, no sediment control system will be installed. <br />After the system is no longer needed, the borehole will be grouted from the bottom to the top. An Octo plug will be <br />placed 10 feet below the surface, and the remainder of the hole will be backfilled with soil material. <br />• <br />40 <br />TR09 -70 2.05 -51 12/31/09 <br />
