RE: Update Letter to Inspection Topics for Inspection Report Dated 10 -1 -2014, Turnpike
Mining Resource, DRMS Permit No. M- 2004 -009
Dear Mr. Scott:
r
As I stated in our recent e- mails, I am giving you an update with explanations of the progress
made on your referenced inspection topics and the status of the corrective actions and due dates
cited. Please note the following:
1. Hydrologic Balance /Monitoring As I have noted to you already, I am scheduled to put
down these three wells in the approved locations on 10- 28 -14. The corrective action due date
is 10- 31 -14, but the intent for the wells was to get baseline data for at least a year prior to the
start of backfilling of the shale in any area nearby to where the wells are to be located
(related to mounding and shadowing of nearby neighbors). Any backfill will start in the far
northern area of the current location for mining, well north of the Schell residence. The
groundwater flow direction is SE to the NW, and mounding would not occur in this northern
area at the time of backfill that would affect the Schell residence. The other two locations
near to the potentially affected neighbors are far to the south and southwest and will not be
mined/backfilled for some years to come. Please see Attachment I for an approved Notice of
Intent to Construct Monitoring Holes from the State Water Resources Dept. I will copy the
DRMS on the monitoring well permits from the Water Resources Dept. once they have been
approved.
2. Compliance with Mine Plan: The corrective action due date for this topic is 12- 31 -14. A
technical revision will be submitted to the DRMS by 12 -31 -14 addressing changes to the
mine plan showing areas of new mining due to the removal of oil and gas wells and flowlines
and re- mining of a small area in the central portion of the permit site due to the floods of
September 2013 and Boulder Cr. jumping its banks into the mine site. These are slight
changes, but will present a more correct and up -to -date version of the mine plan. Any
increase or decrease in bonding will also be rectified. With regard to the importation of
materials (hardened asphalt and concrete chunks) into the site for recycling and that activity
not being a part of the mine plan, this topic will also be addressed in the TR. We have
scheduled a meeting with Weld County to propose these activities on this site and to see what
