This letter responds to the Division's <br />comments in that letter, which we submit to you in advance of the date of March <br />31, 2005, requested in the DMG letter of January 26, 2005, acknowledging the <br />change of decision date in this case. <br />A complete set of revised drawings is provided with this adequacy response. <br />Changes prompted directly by the Division's letters of January 21 and January <br />26, 2005, are discussed by topic below. In addition, two other changes have <br />been implemented on these plans based on the applicant's effort to address <br />potential adequacy issues as thoroughly as possible. <br />1. Benches have been widened on the east face of the quarry and <br />southwest face of the processing area to conform to site-specific rock <br />mechanics addressed in the report of John Abel. These revisions are <br />related to measurement of total surface area that will be disturbed to <br />accommodate operations and are discussed in further detail below, <br />under 6.4.4 -Mining Plan -Maximum Disturbance. <br />2. The proposed point of access from State Highway 119 has been <br />moved to a point approximately 700 feet south and east of the access <br />initially proposed. This will require additional blasting and earthwork at <br />the commencement of operations. Additional rock generated by the <br />change in access point will be trucked off-site or absorbed into the <br />waste rock pile without altering its footprint. The new access point also <br />extends the permit and statutory "affected" area to a new intersection <br />
