The holes <br />will be marked. Landmark requests approval of this closure by the <br />division. <br />The SEDCAD information contained in the mine permit <br />information indicates the 36" culvert at the crossing will handle <br />the runoff from 37.742 acres. Landmark does not plan to continue <br />with the mine plan to mine Phase II which will result in a 6.28 <br />acre reduction in surface disturbance, or a 17.4$ reduction. The <br />two existing 24" culverts are an 11B reduction in capacity from the <br />36" culvert so it is indicated that the existing 24" culverts are <br />adequate. <br />Enclosed are the results of the well water analysis. There <br />was no discharge from the Engleville Mine. <br />Please call me if you have any questions. <br />Si cerely, <br />%~~~ <br />Mark Kerr <br />Operations Manager <br />4901 Soulh Windermere Street.
