As additional information which <br />may affect the Southfield Permit is obtained and verified, EFCI will work closely with the <br />DRMS to evaluate and address future permitting requirements and scheduling. <br />Southfield's total permit area encompasses approximately 2,735.2 acres. This total <br />includes approximately 2,713.3 acres in the mine area and 21.9 acres in the loadout area. The <br />original permit application submitted by Dorchester in 1981 was for a permit area of <br />approximately 1,400 acres. The total permit area increased approximately <br />190 acres as a result of three incidental boundary revisions submitted during the <br />period from 1986 through 1989. These revisions are presented in exhibit 15, Minor and <br />Technical Revisions, an additional 1,232 acres were added to the permit area <br />as a result of permit revision PR -01 and several small incidental boundary revisions <br />subsequent to late 1990. Modification of the maximum subsidence angle of draw in <br />early 1994 and associated changes in the permit boundaries resulted in a net reduction in <br />the permit area of approximately 86 acres. <br />It should be noted that while the total permit area has increased significantly, the <br />surface disturbance area has remained essentially the same at approximately 106.3 <br />acres. Of this total, the mine disturbance area accounts for approximately 90.9 acres <br />with the remaining 15.4 acres of disturbance in the loadout area. <br />2.05-8 <br />Revised 6/30/15 MR -67 <br />
