The following inspection tonics were identified as having Problems or Possible Violations. OPERATORS
SHOULD READ THE FOLLOWING PAGES CAREFULLY IN ORDER TO ASSURE COMPLIANCE
WITH THE TERMS OF THE PERMIT AND APPLICABLE RULES AND REGULATIONS. If a
Possible Violation is indicated, you will be notified under separate cover as to when the Mined Land
Reclamation Board will consider possible enforcement action.
INSPECTION TOPIC: Hydrologic Balance and Offsite impacts
PROBLEM: Alluvial groundwater is mounding against the slurry wall at the Stagecoach Pit, causing an elevated
groundwater table up gradient from the slurry wall. Significant constrictions in alluvial groundwater flow have
resulted in elevated lake levels in Zigan Lake. This is a problem for failure to minimize the disturbance to the
prevailing hydrologic balance pursuant to C.R.S. 34- 32.5116(4)(h) and for failure to protect areas outside of the
affected land from slides or damages occurring during the mining operation pursuant to C.R.S. 34- 32.5 - 116(4)(1).
CORRECTIVE ACTIONS: Submit to DRMS by September 22, 2014 a groundwater mounding mitigation plan
as either a Technical Revision or Amendment to the permit. The plan must include:
1. A detailed description of the measures the operator will take to reduce groundwater mounding outside the
Stagecoach Pit to a level that eliminates elevated levels in Zigan Lake,
2. A time schedule for implementing the plan, and
3. Enough information for DRMS to estimate the cost of implementing the plan (for establishing the amount of
required financial warranty).
CORRECTIVE ACTION DUE DATE: 9/22/14
