upstream of the reservoir, and other appropriate locations to determine the potential
source.
• Weekly monitoring will be performed at the outlet of the Reservoir and downstream
of the confluence of the Eagle River until it can be demonstrated that no
exceedences are occurring which may be caused by the Eagle Park reservoir
delivery.
• Any two consecutive exceedences of the water quality standards at the down stream
point on the Eagle River shall result in an immediate reduction of discharge flow
sufficient to result in an in-stream water quality protective of the use classifications
for Segment 3 of the Eagle River (i.e. attainment of WQS). If there is sufficient
reason to believe that an emergency condition exists related to aquatic life in the
Eagle River, based either on the water quality data observations or the condition of
the aquatic life itself, the DMG may require Climax to immediately reduce or
discontinue discharge from the Eagle Park Reservoir such that the water quality
standards will be met.
• Contingency monitoring at the downstream point on the Eagle River may cease after
it has been demonstrated that no exceedences have occurred for any two
consecutive samples for the water quality standards that were exceeded.
• If it is determined that the source of the problem is related to sources upstream of the
reservoir, or mining materials in the reservoir, Climax Molybdenum Company, will
restore, as quickly as practicable, operational controls on the Eagle Park Reservoir
or the approved Climax Environmental Protection Facilities to prevent further
exceedences. Based on mutual agreement by the Division of Minerals and Geology
and Climax, alternative methods of addressing the cause of the exceedences other
than restoration of operational controls can be implemented.
Condition No. 3
Water quality analytical results obtained during periods of water delivery from Eagle Park
Reservoir will be submitted to the DMG and the WQCD within 30 days of receipt of the
results.
A report that summarizes the results of the three-year monitoring program will be submitted
to the Division of Minerals and Geology and WQCD no later than 90 days following receipt
of the results of the last sample.
Climax Molybdenum will notify DMG verbally or via facsimile within five (5) business days of
the receipt of results that show an exceedence of a water quality standard or determination
that the reservoir is the source of an exceedence.
Condition No. 4
Climax understands that additional conditions to approval of SR-002 require completion
prior to final acceptance of the Application for Reduction of Warranty. Climax reserves the
right to object to these requirements as specified by the MLRA.
