DMSION OF REDITI@Hi
MINING AND iMPY
We have reviewed your letter of January 30, 2015, requesting a renewal of the
substitute water supply plan ("SWSP") on behalf of Everist Materials, LLC ("Everist" or
"Applicant") for the Maryland Creek Ranch ("MCR") aggregate operation in accordance with S
37-90-137(11), C.R.S. The mine is permitted with the Division of Reclamation, Mining, and
Safety ("DRMS") under File No. M-1996-049. The required fee for the substitute water supply
plan was submitted under Receipt No. 3668280. The original plan was approved on April 3, 1997
and it was most recently renewed on March 19, 2014.
SWSP Operations
The MCR aggregate operation is located on the west bank of the Blue River,
approximately 6 miles downstream of Dillon Reservoir and 20 miles upstream of Green Mountain
Reservoir. Gravel mining operations take place at an elevation of approximately 8,550 feet,
within a distance of 2,200 feet of the Blue River, in Sections 15, 22 and 23, all in Township 4
South, Range 78 West of the 6th P.M., as shown on the attached Figure A-3. Mining operations at
MCR include gravel mining from wet pits, a crusher and wash plant, an asphalt plant, and a
concrete batch plant. Product below the ground water table will be removed via "wet mining"
techniques, therefore dewatering of the pits will not occur, and is not approved herein. Under
the DRMS permit, Everist received approval to mine a total of 6 mining cells. Mining operations
in cells nos. 1, 2 and 3 were finished. Following mining, Cell No. 1 was utilized as a tailing pond
and has been backfilled. The surface area of ground water exposed in cell nos. 2 and 3 totals
approximately 25.1 acres. Mining is currently taking place in cell no. 4 where the surface area
of the exposed ground water is approximately 8.0 acres. The total surface area of ground water
exposed in the cells 2 through 4 is estimated to be 33.1 acres. No change in the ground water
exposed surface area is expected to occur during 2015 and 2016. Replacement water is to be
provided using consumptive use credits from dry -up of historically irrigated land and releases of
storage water from Green Mountain Reservoir and Dillon Reservoir.
