discussed on Page 2.05.4-12. The description of the sealing method appears to be <br />adequate. The Division, however, requests that the operator provide a detailed figure <br />showing the reclamation of the ventilation shaft, including the reclamation of the collar, <br />filling of the shaft and the placement and dimensions of the vent pipe. <br />Northfield Response: Requested information was provided. <br />DRMS: Response accepted. <br />9. There is a typographical error on the third line of the second paragraph on Page 2.05.3- <br />13.

On page 2.05.3-13 Northfield discusses the Mine Office Building. In the discussion of <br />dimensions of the building there is no height stated.

Please include a building height and a description of the stemwalls in the <br />discussion of the Mine Office Building and resubmit the page. If Northfield has an <br />engineering design for the building this would be helpful for bonding purposes. <br />Northfield Response: Requested information was added. <br />DRMS: Response accepted. <br />11.
