Dear Mr. Kraig: DIVISION OF RECLAMATION,
MINING AND SAFETY
We have received your letter dated July 1, 2015 requesting the renewal of the above
referenced substitute water supply plan ("SWSP") to cover depletions caused by an existing
gravel mining operation at the Heit Sand and Gravel Mine in accordance with 5 37-90-137(11),
C.R.S. The required fee of $257 for this SWSP renewal has been received (receipt no.
3670470).
Plan Operation
The Heit Sand and Gravel Mine perimeter was lined with a slurry wall in accordance
with the State Engineer's Lining Criteria, and was approved by the Division Office on June 24,
2009. In accordance with paragraph 21 of the General Guidelines for Substitute Water
Supply Plans for Sand and Gravel Pits, the applicant is required to provide replacement for all
native ground water remaining within the lined area that is put to beneficial use except for
the water removed with the mined product. The water may be removed from within the
lined area and returned to the stream system through surface flow or ground water recharge
without need for replacement, so long as the operator does not put the water to beneficial
use. Replacement shall be made for native ground water that is lost to evaporation. For
purposes of this SWSP, it is assumed that all water within the lined area is trapped native
ground water. Therefore, this plan will account for depletions resulting from evaporation of
exposed water within the lined area. Operational depletions at the site will consist of water
used for dust control and for washing of the mined aggregate using an onsite production well.
All water used from the production well must be replaced in time, place and amount
including water used for washing of mined product. Total depletions for the Heit Sand and
Gravel Mine during the period of this SWSP will be replaced by fully consumable water leased
from the City and County of Broomfield.
In accordance with the letter dated April 30, 2010 from the Colorado Division of
Reclamation, Mining, and Safety ("DRMS"), all sand and gravel mining operators must comply
with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations
for the protection of water resources. The April 30, 2010 letter from DRMS required that you
provide information to DRMS to demonstrate you can replace long term injurious stream
depletions that result from mining related exposure of ground water. The DRMS letter
identified four approaches to satisfy this requirement. A surety reduction was approved on
March 23, 2010 by DRMS reducing the bond by $110,614 - representing the remaining 20% of
