(OSMI) requests a 30-day extension to the decision date for TR-12 <br /> from June 16th, 2021 to August 15th, 2021. OSMI is requesting the extension due to delays in <br /> sampling. The sample bottles from the first resampling event to determine the source of Bis(2- <br /> ethylhexyl) phthalate in GW-4 were broken while being shipped to ACZ Laboratories. A new <br /> bottle set was ordered and the well has been resampled. Results from the GW-4 resampling were <br /> received from ACZ on July 141h. OSMI is requesting this extension in order to allow time for the <br /> laboratory results to be validated/interpreted and to provide the Division with sufficient time to <br /> review responses to the adequacy review comments. <br /> OSMI appreciates your attention to this matter. If you have any questions, please contact me at <br /> (970) 325-9830. <br /> Sincerely, <br /> C- L <br /> Todd Jesse <br /> Environmental Specialist <br /> Ouray Silver Mine Inc <br /> Cc: Travis Marshall, DRMS <br /> Amy Yeldell, DRMS <br /> Brianna Greer, SSG <br /> Brian Briggs, OSMI <br /> Phone:(970)325-9830 ♦ Fax: (970)325-9824 <br />
