Dear Ms. Hatcher:
This letter is in response to the application submitted on August 30, 2007 requesting a
substitute water supply plan ("SWSP") for a sand and gravel pit to be operated by Lafarge West,
Inc. ("Applicant°) in accordance with Section §37-90-137(11), C.R.S. The required fee of $257.00
for the renewal of this substitute supply plan has been submitted (receipt no. 3620765). The
original supply plan was approved on May 1, 2006.
Plan Operation
This plan seeks to replace depletions resulting from mining at the Lupton Lakes Resource
Pit ("Lupton Lakes"). The depletions that result from the mining operation are evaporation, water
lost in mined product, concrete batching and dust suppression. The Applicant plans to begin
dewatering at the site in November of 2007 to allow dry mining. Depletions will also result from
the dewatering operation.
The request specifies that wells 19490S, 7280R, 20317R, 1408R, 2819F, 1657RR,
2820F, 20583R, 12800R and 19944RF will be used to provide process water to the mining
operation. All of the wells are located within the gravel permit boundary in sections 18 and 19,
Township 1 North, Range 66 West, 6th P.M. The Applicant has submitted well permit applications
to repermit the wells to the requested use.
The proposed replacement source is fully consumable water leased from the City of
Aurora ("Aurora"). If the mine is dewatered and dry mined, water discharged from the pit during
dewatering operations that is in excess of the lagged impacts of the dewatering operation itself
will be used as a replacement source in this plan.
The final reclamation of the pit includes backfilling of all exposed groundwater within the
permit boundary. The Applicant has obtained a bond in the amount of $3,618,200 for backfilling of
the pit, as part of their permitting process through the Division of Reclamation Mining and Safety.
