NECC plans to install a conveyor system that will transport development waste from the <br />east side of the development waste disposal pile to the refuse disposal area conveyor. The new temporary <br />conveyor system will be permitted under minor revision number 101. <br />This technical revision will facilitate the installation of the conveyor system. Three new culverts will be <br />installed along the proposed conveyor corridor. The haul road located north of the development waste <br />disposal area will be extended to the proposed loading point for the conveyor. The classification of an <br />access road located south of the coal preparation plan will be changed to a haul road. <br />An additional five culverts were added to Map 13. Exhibit 19(18) presents the culvert sizing rationale and <br />calculations for the new culverts. The second paragraph on page 2.05 -4a was amended to briefly discuss <br />the proposed conveyor corridor. <br />A'reclamation estimate for the three new culverts is provided as Exhibit 28. <br />Sincerely, <br />J.
