Dear Jennifer S. Lindahl, P.E.:
We have reviewed your letter dated November 5, 2021 requesting renewal of the substitute water
supply plan ("SWSP") to cover depletions at the Morton Lakes Mine ("Morton Lakes") and Holton
Lake Mine ("Holton Lakes"), operated by Brannan Sand and Gravel Company LLC ("Brannan" or
Applicant"). On March 6, 2017 the Colorado Division Mining and Safety ("DRMS") approved the
incorporation of the Holton Lakes Mine into the Morton Lakes Mine, therefore both mining permits
are now operating under Morton Lakes Mine (M-2008-082).
The previous SWSP for the Morton-Holton Lakes was approved on November 24, 2020 to cover
operations for October 1, 2020 through December 31, 2021. The required fee of $257 for this SWSP
has been submitted (receipt no. 10016738).
SWSP Operations
The Morton-Holton Lakes Mine is located in the SE '/a of Section 1 and the NE '/a of Section 12, all in
Township 1 North, Range 67 West of the 6th P.M., and the SW '/a of Section 6, and the NW '/a of
Section 7, all in Township 1 North, Range 66 West of the 6th P.M. The depletions that result from
the mining operation over the period of this SWSP include evaporation from exposed groundwater,
dust suppression, dewatering, water used to wash mined product, water removed in mined product,
and water pumped for construction of a slurry wall at Stage 7A and Stage 7B.
Mining of the Morton Lakes site is presently expected/projected to last until at least 2026. The
current mining plan for the site is shown in attached Figure 1. The replacement of depletions for
Morton-Holton site is fully consumable water leased from the City of Aurora.
The mining status of the Stages is described below:
• Stage 1 Mining at Stage 1 was completed in July 2016.
