Based on the complete bond release inspection conducted on May 30, 2012 several issues were observed
that will need to be addressed for the Phase III bond release (SU) for the Hamilton Mine.
Permit Section 2.05.6 (3) Water Monitoring Plan
1.) As you are aware, Honeywood is required to complete the water monitoring plan as outlined in
section 2.05.6(3) of the permit and demonstrate damages to the hydrologic balance have not occurred.
Rule 4.07.1(1) Monitoring Well Abandonment
2.) There appears to be seven alluvial wells that have been monitored in the past for the Hamilton Mine.
Alluvial Wells 1 and 2 were monitored until 1990 and Alluvial Wells 3 -7 were monitored through 1998
until cessation of monitoring was approved in 1999. Also, three bedrock monitoring wells are in place.
The Division could not find any record these wells have been properly abandoned and sealed, and some
of these wells are required to be monitored prior to full site release. An attempt was made to ascertain
the status of the alluvial wells reported to have been destroyed in a local flood (AW -4, 5, 6, & 7) during
the May 30, 2012 site inspection. The wells in question are located on Reams Construction property.
Based on the inspection it appears several of these wells are still intact.
In accordance with Rule 4.07.1(1) each well shall be plugged, sealed or otherwise managed, as approved
by the Division to prevent acid or other toxic drainage from entering ground or surface waters; minimize
disturbance to the prevailing hydrologic balance; and ensure the safety of people, livestock, fish and
wildlife and machinery in the permit and adjacent areas. Given this, Honeywood will need to gain
access and document the conditions of all the monitoring wells. This information will need to be
submitted to the Division. All of the monitoring wells (AW 1,2,3,4,5,6,7 and BW 1,2,3) will need to be
abandoned and sealed in accordance with Rule 4.07 as discussed above. Or, if the landowners desire for
these wells to remain in place, in accordance with Rule 4.05.14 the wells can be transferred to their
control and a well permit must be obtained from the State Engineer.
