MINING AND SAFETY
Dear Mr. Parsons:
We have received your letter of August 15, 2014, requesting approval of the above referenced
substitute water supply plan ("SWSP")to cover depletions caused by an existing gravel mining operation.
The required application fee of$1,593 for an expired SWSP has been submitted (receipt no. 3666428).
The original SWSP applied for by South Platte Sand and Gravel LLC was approved on April 30, 2001 and
has been renewed since that time. The prior SWSP was renewed by letter dated August 17, 2012 and
that plan expired on June 30, 2014. A new SWSP application was submitted to the State Engineer's
Office on September 3, 2014.
Plan Operation
This plan seeks to replace depletions resulting from mining at the S&H Mine Gravel Pit ("S&H
Pit") operated by Gilcrest Reservoir LLC ("Applicant"). Gilcrest Reservoir assumed operational and
ownership control of the mining site from Platte Sand and Gravel LLC when the Succession of
Operators was approved by the Division of Mining Reclamation and Safety ("DRMS") on February 2,
2011. There are no current mining activities occurring at this pit and as such the only depletions
covered under this SWSP are those caused by evaporation from a ground water pond that resulted
from past mining operations. Should mining activities resume an amendment to this SWSP will be
required.
The S&H mine permit area covers approximately 750 acres and is divided into different cell mines.
The two structures included in this SWSP are Sharkey's Reservoir (aka Sharkey's Lake -WDID 0203977)
and Sharkey's Pond. The liner of Sharkey's Reservoir has been completed and based on a Division of
Water Resource's liner approval letter dated May 22, 2009, the pit has been lined to the design standard
referenced in the August 1999 State Engineer Guideline for Lining Criteria for Gravel Pits. The proposed
replacement source is water stored in-priority within Sharkey's Reservoir.
Depletions
According to the information submitted, no water surface was exposed within the permit boundary
prior to January 1, 1981. Sharkey's Pond currently exposes 10.8 acres of ground water. Using are annual
gross evaporation of 43 inches per NOAA TR-33, and an effective precipitation of 8.66 inches per year, the
