OBSERVATIONS
The Cottonwood Quarry, File No. M-2004-061, was inspected by Peter Hays with the Division
of Reclamation, Mining and Safety (Division) as part of the Division's 4-year monitoring
inspection program. Mr. Richard Linke representing Linke Construction Inc. was present
during the inspection.
The Cottonwood Quarry is located approximately 2.5 miles southeast of Granby, Colorado on
State Highway 40 and 2 miles west on Grand County Road 55. The site is permitted for
94.41 acres and was previously inspected by the Division on November 19, 2004.
The Cottonwood Quarry 112c reclamation permit was approved by the Division on December 10,
2004. The approved mining plan indicates mining will begin on the southern part of the
property on an existing natural bench above County Road 55. Material will be removed from
the natural bench until enough room exists to move a processing plant into the mined area.
Mining will advance to the north by creating 40 foot by 40 foot benches.
The processing plant bench has been created and the first 40' x 40' bench has been created
northeast of the plant area. The hilltop northeast of the lower bench is being mined.
The active highwall is approximately 30' high with an additional 35' of hilltop above the
highwall. Mr. Linke stated a road would be constructed from the west side of the hilltop
to allow mining to continue from the top down. The processing plant and job trailer were
located on the lower bench. A portable asphalt plant was located north of the processing
area and west of the active mining bench. The permit application anticipated blasting
being required to mine the site. Mr. Linke stated blasting has not been required since
the rock has been fractured enough to allow mining to occur with an excavator.
Linke Construction committed to placing a 6-mil vapor barrier liner under the fuel storage
area and up the sides of the containment berm sufficient to contain any spill or leak
during the adequacy review. Mr. Linke stated the fuel storage area has not been required
for mining operations. Fuel storage and oil storage tanks were observed in the asphalt
plant area and both tanks were lined and bermed.
A storm water retention pond was located in the southeast corner of the site as required
by the mining plan. The required 25 foot offset from the east and west boundaries were
observed.
The additional rock analysis suggested by the Division during the permit application
adequacy review as not been completed. Linke Construction agreed to complete the analysis
when enough rock face had been exposed to do a proper analysis and proposed limiting the
mining disturbance to 20 acres until the analysis was complete. The 20 acre disturbance
was expected to occur after the first four 40 foot benches had been complete, which has
not occurred at the time of this inspection.
The Division currently holds a financial warranty of $84,073, which is adequate to
complete the reclamation of the site based on the observations from this inspection.
An entrance sign was posted and permit boundary markers were observed as required by Rule
3.1.12. No problems were noted during the inspection.
