''~ <br />Rob Mangone -2- May 21, 1992 <br />At the time of the pre-operation inspection, you showed the inspector new <br />0~/~ locations for the proposed access roads. Show the new access road <br />locations on revised mine plan maps and make any necessary changes to the <br />mining and reclamation plans. <br />"h4. At the time of the pre-operation inspection, you stated that you wanted <br />,p ~ U, to have the option of mining areas shown on your mine plan map as having <br />l~ excessive overburden and not economical to mine. Remove reference to <br />/ these areas from the mine plan map and mining plan and include them in <br />,/,y, the affected land boundary. <br />Uv Show on the revised mine plan maps the area referenced as State Historic <br />Preservation Office (SHPO> Site No. 5FN1084, and state what type of <br />barrier or other method you will use to make sure the site is not <br />impacted before receiving clearance from SHPO. <br />You stated during the pre-operation inspection that you will have <br />~Q ~ ~ approximately 20 acres of major disturbance as opposed to the 15 acres <br />"1, i stated in the mine plan. If the five acres of plant site will require <br />(UUl backfilling, grading, and topsoiling prior to the revegetation phase of <br />reclamation, they should be removed from the moderate disturbance <br />category and added to the major disturbance Category. Please clarify the <br />major and moderate disturbance acreages. <br />~~~+ <br />8 <br />~~ <br />You stated at the pre-operation inspection that you plan to have (at <br />times) a portable batch and/or asphalt plant within the processing area <br />in addition to the crushing and screening operations stated in your mine <br />plan. Change your mine plan to include these features, or plan to add <br />them after permit issuance with a technical revision to the permit. <br />Y•'~~' <br />~~Your mine plan and reclamation plan are not Clear about the required <br />segregation of topsoil from other overburden materials. Show typical <br />stockpiling plans on your revised mine plan map and discuss in more <br />detail topsoil and other overburden handling in the mining plan. <br />xhibit E - Reclamation Plan <br />~~\ <br />~ V <br />'1 <br />Your reclamation plan states that at the floor edges adjacent to steep <br />slopes a berm will be provided to prevent slope erosion and erosion of <br />the reclaimed area. During the pre-operation inspection, it was agreed <br />that these berms would be eliminated from the reclamation plan and that <br />the pit floor would be blended Edith the natural slope to allow natural <br />sheet flow of surface water. Good and timely reclamation practices <br />!should eliminate most erosion of areas outside of the affected land. <br />~l,ease make appropriate changes to your reclamation plan. <br />,In accordance with Rute Z.1.2(6)(f)(v), specify anticipated minimum depth <br />or range of depths for those areas where topsoil will be replaced. <br />LDO/bjw <br />3254E <br />
