Carter <br /> [OVERNIGHT MAIL DELIVERY] <br /> APq �tlll�/ <br /> April 25, 2017 IWS1CN <br /> MiN��°� ''A.FI�trt®�y <br /> r <br /> Mr. Michael Cunningham <br /> Environmental Protection Specialist II E!R ) <br /> Division of Reclamation Mining and Safety 25 <br /> Department of Natural Resources <br /> 1313 Sherman Street, Room 215 ✓3 Violations:MV_ <br /> Denver, CO 80203 2010-018,2010-030 <br /> 2012-027 <br /> RE: Schwartzwalder Mine; DRMS File No. M-1977-300; Technical Revision -25, <br /> Amendment to Technical Revisions -23 and -24 <br /> Dear Mr. Cunningham: <br /> Please find Cotter Corporation(N.S.L.)'s ("Cotter's")request for Technical Revision ("TR")-25 <br /> along with a check in the amount of$1,006 for the Technical Revision fee. During a telephone <br /> conversation on March 30, 2017, Cotter informed the Colorado Division of Reclamation, Mining <br /> and Safety ("DRMS") that Cotter omitted one source of materials from its Technical Revision <br /> ("TR'")-23 inventory for the Minnesota Adit. Specifically, certain alluvial materials, also <br /> regulated by Cotter's Radioactive Materials License ("RML") 369-06, may need to be placed in <br /> the Minnesota Adit depending on whether or not radium-226 concentrations meet Cotter's RML <br /> cleanup criteria. DRMS informed Cotter that a technical revision is required to add a volume <br /> estimate of these materials to Attachment F of TR-23. Therefore, Cotter is submitting TR-25 to <br /> amend Attachment F, which is the Minnesota Adit inventory list. <br /> TR-25 also amends TR-24, which addresses the construction of a new water treatment plant on <br /> the mesa portion of the Schwartzwalder Mine near the Steve Adit. TR-25 provides information <br /> regarding new process tanks that were added to the treatment plant after TR-24 was approved. <br /> Information contained in TR-25 addresses requirements found in Rule 6.4.21(7). <br /> Cotter Corporation Telephone (719) 275-7413 <br /> Canon City Mill, 1700 Fremont Co. Rd. 143, Canon City,CO 81212 USA Fax (719) 275-1669 <br />
