Lochhead <br />Exerutrve Director <br />Michael B. Long <br />Division Director <br />We have received a permit revision application from Jim Stover (for Oxbow Carbon and <br />Minerals) to add 160 acres to the Sanborn Creek Mine permit area. In addition to the 160 <br />acres, they have applied for a BLM right-of-way to mine through a 40 acre parcel along the <br />eastern boundary of the additional acreage. The revision was deemed complete on May 23, <br />1996. Our adequacy comments need to be submitted to the operator by July 22, 1996. <br />I am coordinating the review of the permit revision, since there is currently no lead specialist <br />for this mine. I am requesting your assistance in the following areas: <br />Mike <br />:1.Gy,~ General Description of Hydrology and Geology (groundwater portion of hydrology only) <br />2.oy, E Geology Description <br />Z,uV,1(I) Groundwater Information <br />a,oSa Mitigation of the Impacts of Mining Operations (groundwater) <br />'x.05.4 ~ Protection of the Hydrologic Balance (groundwater) <br />-!.cs,~~Jim <br />Subsidence Survey <br />Subsidence Monitoring <br />Subsidence Control Plan <br />Mitigation of the Impacts of Mining Operations (subsidence) <br />All of the Bowie No. 1 Mine permit application materials and files are located in the empty <br />office next to the refrigerator room.
