As noted in the <br />memo, the modeling "appears" to meet our requirements. But additional parameter quantification is <br />necessary to support the findings. Please submit the additional information requested by DMG staff to <br />the Grand Junction Field Office. I will forward on the information to appropriate staff as soon as it is <br />received. If you have additional questions regarding this request, it is best to talk directly to Kate <br />Pickford or Harry Posey directly. Their numbers are noted at the bottom of the attached memo. <br />In the interim, DMG has postponed the Formal Hearing on this matter until January 11 tb and 12`h, 2006. <br />If you need additional information, please contact me at the Division of Minerals and Geology, Grand <br />Junction Field Office, 101 South Third Street, Room 301, Grand Junction, Colorado 81501, telephone <br />no. 970-241-1117. <br />Sincerely, <br />- ~ ~!~o~ <br />G.
