The following inspection topics were identified as havinu 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
PROBLEM/POSSIBLE VIOLATION: Problem: Property owner to the north of the permit (A&W Water Service Inc.)
has reported impacts (inability to pump at previous rate) to their production well located approximately 650
north of operator's unlined Stage 6 mining cell. This complaint is substantiated by monitoring well data from
the immediate area showing significant declines in static groundwater levels throughout 2017 and early 2018.
This a problem related to 34-32.5-116(4)(h) of the Colorado Revised Statutes and 3.1.6(1)(a) of the Construction
Materials Rules and Regulations which require that disturbances to the prevailing hydrologic balance be
minimized.
CORRECTIVE ACTIONS: The operator has recently implemented corrective action as approved in TR05 (see
attached photos). This action has already resulted in a measured increase in groundwater levels near the A&W
well of approximately two feet. The operator stated that they intend to increase the groundwater level in the
recharge area as soon as possible to further minimize impact to the hydrologic balance.
DRMS will require that a stability analysis be performed on the existing/proposed compacted earth berm
currently dividing Stage 6 as soon as possible, and the final design be submitted to DBMS as a technical revision
prior to increasing the berm elevation, or raising the water level in the existing recharge pond. DRMS will also
