Since <br />regulations apparently require inspection on these structures it <br />seemed redundant to commit to further inspections over and above <br />the regulations. For this reason the page headed INSPECTION <br />SCHEDULE is proposed to be replaced by the enclosed page following <br />your approval. <br />Following your approval of M.R. #29 a copy of the page will be sent <br />to the required Federal agencies to update their permit documents. <br />Thank you for your attention to this matter. Should you have any <br />questions regarding *_he enclosed materials, please contact me at <br />the Edna Mine site. <br />Sincerely, <br />~~~ <br />David Beverlin <br />Resident Engineer <br />
