Permit Amendment (AM-06) - Climax Mine
CM0000475
• in some areas. The Robinson TSF has been capped with a rock cover and reclaimed using biosolids.
The 2 Dam Spillway and a portion of the East Side Channel (ESC) have been constructed and are
operational. Portions of the E and F Dumps have been recontoured and seeded. The E and F Dumps
are located within the footprint of the overburden storage facility (OSF) now termed the North 40 OSF.
The water treatment system has been upgraded with the installation of an on-line lime slaking facility and
Sludge Densification Plant (SDP). A high capacity pump station was installed at the base of 3 Dam as
part of the water treatment system upgrades. Numerous historical mine sites have been remediated and
reclaimed. Finally, as previously mentioned, numerous unneeded buildings and structures in the mine
and mill area have been dismantled and demolished.
Infrastructure upgrades and system improvement projects previously approved under TR-14 are in
various states of construction and include the rehabilitation of Tenmile Tunnel, a new Tailing Delivery Line
(TDL), the Robinson Lake Pump Station and Pipeline and the new mill building.
Major components and facilities at Climax include the open pit and underground mine, overburden
storage facilities, or OSFs (McNulty and North 40), crusher and mill complex, the process water reservoir
(Robinson Lake; aka: Robinson Reservoir) and its circuit, fresh water reservoirs (Chalk Mountain
Reservoir and Buffehrs Lake) and their circuits, the SDP and the tailing storage facilities, or TSFs
(Robinson, Tenmile, and Mayflower) and the clear water Interceptor System. Ancillary fresh water
facilities not owned by CIVIC, including Clinton Reservoir and Eagle Park Reservoir, are important site
features and part of Climax's water management system. Since the Climax Mine dates to 1917, many of
these components or their predecessors are historic, pre-dating the Colorado Mined Land Reclamation
Act by decades.
Detailed locations, descriptions, and map references of specific environmental protection facilities are
found in Section T-5 and in the attached appendices as referenced throughout. Figure AM-06-T-01
illustrates the locations of major components and facilities.
Detailed physical and environmental descriptions of the site including location maps have previously been
submitted in the 1977 Climax Mining and Reclamation Permit (Sections T-3, T-4, and T-7) and five (5)
amendments and 15 technical revisions that have been submitted to the DRMS. Updated physical and
environmental descriptions of the site including location maps are also provided in the Exhibits to this
permit amendment AM-06.
T-2 Other Agency Environmental Protection Measures
T-2.1 General Information
The Climax Mine is regulated at various levels by the DRMS, the Colorado Air Pollution Control Division
(APCD), and the Colorado Water Quality Control Division (WQCD). The latter two divisions are within the
Colorado Department of Public Health and Environment (CDPHE). The WQCD administers Climax's
Colorado Pollutant Discharge System (CPDS) permit and a stormwater permit. As part of the stormwater
permit, Climax maintains a Storm Water Management Plan (SWMP). The SWMP addresses the handling
of water that is outside of the water treatment system at Climax.
Other state and federal agencies that regulate or oversee activities at the Climax Mine include the
Colorado State Engineer (dam safety and water rights), Colorado Department of Transportation (CDOT),
Colorado Hazardous Materials and Waste Management Division (within CDPHE), Mine Safety and Health
Administration (MSHA), U.S. Environmental Protection Agency (EPA), and the U.S. Army Corp of
Engineers (ACOE). Since lands within the DRMS permit areas are privately owned, there is no federal
land management agency regulation of the site. The singular exception to this private land ownership is
the Humbug extension of Supply Canal No. 1, which is located on U.S. Forest Service (USFS) land and
permitted with a Special Use Permit from the USFS. The USFS administers lands surrounding Climax.
Specifics of environmental protection measures and monitoring as required by Rule 6.4.19(3) are
discussed in Section T-2.2, and in Sections T-5, T-6, and T-7 herein.
