Environmental Protection Plan, Schwartzwalder Mine 4-1 • 4. OTHER PERMITS AND LICENSES Rule 6.4.20(5) requires that the EPP list any air, water quality, solid and hazardous waste, and other federal, state permits or local licenses, or other formal authorizations which the Operator/Applicant holds or will be seeking applicable to the use, handling, storage, or disposal of designated chemicals and acid mine drainage-forming materials within the permit area. The Schwartzwalder Mine operated under Colorado Mining Permit # M-1977-300, Colorado Discharge Permit #CO-0001244 and Radioactive Materials License CO-369-03. (a) Colorado Mining Permit #M-1977-300 The mine permit (M-1977-300) was issued by the State of Colorado in 1977, and covers 57 acres of Section 25. The permit disturbance boundary covered by the permit is shown in Figure 2-2. (b) Colorado Discharge Permit #CO-0001244 Discharge Permit #CO-0001244 was issued in 1981 by the Colorado Department of Public Health And Environment, Water Quality Control Division for the Schwartzwalder water treatment plant. The original plant treated mine water to remove uranium and radium prior to discharge into Ralston Creek. This plant, which included three in-line ion-exchange columns, has not discharged since June 30, 2002. The Discharge Permit was renewed for the fifth time on April 1, 2005 and was effective through March 31, 2010. An application for renewal was submitted in the fall of 2009, and an administrative extension was granted until renewal could be assessed and issued. A draft of a revised Permit CO-0001244 was posted for public review on July 23, 2010. Renewal of this permit, revised to authorize a new discharge outfall location and with new water quality discharge limitations, is expected by the end of August, 2010. In the interim, authorization to discharge from the new 100-gpm ion exchange water treatment plant to Ralston Creek at the new discharge outfall location (001A) has been granted by the Water Quality Control Division under a temporary amendment to a June 1, 2010 NOV/Cease and Desist Order (order #I0-100601-1). The treatment system is described in Section 15(b) and the permit discharge limits are discussed in Section 11(a)(i) of this EPP. (c) Radioactive Materials License number CO-369-03S The Radioactive Materials License #CO-369-03S was issued by the CDPHE Hazardous Materials and Waste Management Division and is valid for five years. The permit had been renewed every five years since it was first issued. Renewal of this Radioactive Materials License has been in abeyance since 2005, though annual effluent monitoring and reporting requirements have remained in effect. No activities involving licensed radioactive materials have taken place during this time. This license is in the final stages of decommissioning and final termination is expected by the end of 2011. (d) Radioactive Materials License number CO-369-06 A new Radioactive Materials License #CO-369-06 was issued by the CDPHE Hazardous Materials and Waste Management Division on July 29, 2010. This license authorizes storage, possession and ownership of radioactive materials associated with an ion-exchange water treatment system that has been installed in the former water treatment facility building for purposes of groundwater remediation. Operation of this water treatment system is authorized under radioactive materials services provider license #CO-1177-01 held by Water Remediation Technology (WRT). Operation of the ion exchange water treatment system will be performed by WRT under their approved radiation safety program. is 4109C.100731 Whetstone Associates 6
