The following inspection topics 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 Off -site Damage
PROBLEM: Alluvial groundwater is mounding against the backfill of fines at the Worthing Pit, which is
contributing to upgradient groundwater mounding between the Stagecoach Pit and Pit 29. 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)(i).
CORRECTIVE ACTIONS: Submit to DRMS by November 10, 2014 a Technical Revision to the permit,
containing the groundwater mounding mitigation plan described in your letter that DRMS received on September
30, 2014. The plan must include:
1) A detailed description of the measures the Operator will take to reduce groundwater mounding outside of
the Worthing Pit to a level that eliminates elevated groundwater levels in the surrounding area,
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: 11/10/14
