7. The Applicant has stated that the Hoffinan Pit will be mined in phases, with each phase being between 10 to <br />12 acres in size. As required by Rule 6.4.4( e), please provide the following information: <br />We have decided to eliminate "phasing" on this mine as per our conversation. Reclamation will be concurrent <br />with mining with no more than 10 -1Z acres affected that are either undisturbed, or in some stage of reclamation. <br />a. An estimate of the periods of time which will be required for the various phases of the operation; <br />We have eliminated phasing. <br />b. A description of the size and location of each area to be worked during each phase; and <br />We have eliminated phasing. <br />c. Outline the sequence in which each stage or phase of the operation will be carried out. <br />We have eliminated phasing. <br />8. The Applicant has stated that erosion control BMP's will be utilized to protect drainages. Please provide the <br />Division with additional information on the BMP's to be used, including: <br />a. A general description of the placement of the erosion control structures. <br />Berms such as the one used on the West side of the mining area between the affected area and the ravine will be <br />constructed to prevent storm water discharge and erosion. Anywhere there might be the possibility of storm <br />water discharge caused by future excavation, these berms will be put into place. <br />b. Maintenance and inspection plan for the erosion control structures. <br />The berms should be inspected each time mining takes place to insure their integrity. Maintenance would be <br />performed on an as needed basis based on those inspections. <br />c. Describe any vegetative buffers that will be left in place. <br />As mining progresses, moving Bast, there is the potential of encountering more ravines as was done on the West <br />side. A strip of land will be left between those ravines and the affected area. The natural vegetation on that strip <br />will help to prevent erosion. <br />d. A timetable for when the erosion control structures will be removed and the criteria used to determine when <br />the structures will be removed. <br />The original mining plan stated that bales of hay would be put in place to prevent erosion. This was deleted in <br />the revised plan because of the cattle in the same pasture that would make short work of any hay or straw that <br />was left there. But should it be decided that structures such as silt fencing be used in the future, these structures <br />would remain in place until vegetation was established, and the threat of erosion abated. <br />e. A timetable for when erosion control structures will be constructed as mining progresses to a new phase. <br />Berms will be constructed as soon as the potential for storm water discharge is identified. <br />
