Re: Dust & Dirt Excavating Site Specific Development Plan and a Special

Case No. USR-1660
NE114 Sec. 4, T5N, R65W, 6th P.M.
Water Division 1, Water District 3
Dear Ms. Martin:
We have reviewed additional information submitted by the applicant in regards to
the above referenced proposal for a mineral resource development facility including
open pit gravel mining and materials processing. As indicated in our previous letter of
July 2, 2008, since the submitted material does not appear to qualify as a "subdivision"
as defined in §30-28-101(10)(a), C.R.S., pursuant to the State Engineer's March 4,
2005 memorandum to county planning directors, this office will only perform a cursory
review of the referral information and provide comments. The comments will not
address the adequacy of the water supply plan for this development or the ability of the
water supply plan to satisfy any County regulations or requirements.
The applicant indicated that the mine operation is proposed to be conducted in
phases. From the additional information, no ground water will be exposed or used in
the initial Phase 1. For the subsequent phases, 2-7, the mine operation will be
conducted as a dry pit by dewatering the active area with dewatering trenches. From
previously submitted materials, exposed ground water taken from the pit will also be
possibly used for material washing and dust control. However, from the additional
information the source of water for dust suppression will not be exposed ground water
but purchased from the City of Greeley.
Pursuant to §37-90-137(11), C.R.S., exposed ground water due to gravel mining
operations (which, according to the additional information provided, is proposed to occur
during Phases 2-7 of the mining operation) is considered to be a well and a well permit
must be obtained rior to the commencement of any mining activity which would result
in the exposure andlor use of ground water. Since this proposed gravel pit "well"
appropriates water tributary to the over-appropriated South Platte River basin, an
