Shores SWSP
November 26, 2012
will have to obtain permission from the District 2 Water Commissioner to verify the Aurora
effluent can make it past any dry up locations between Metro Sewer and the Saint Vrain Creek.
Any Aurora effluent used to make replacements for the Shores pit will be assessed a transit Toss
based on 44 stream miles. Transit loss is therefore currently 22% (0.5% per mile) but is subject
to change by the water commissioner or Division Engineer. This additional water is only for
November 2012 through February 2013, and is the basis for the duration of this SWSP approval.
This SWSP will expire on February 28, 2013 unless this lease is extended to October 31, 2013, or
a lease sufficient to cover the projected depletions from March 1, 2013 through October 21, 2013 is
submitted to this office by February 1, 2013. Since the Aurora effluent is being used as a
replacement source for multiple plans, the applicant's accounting for each SWSP must specify the
total amount of effluent released on behalf of Bestway's lease, and the amount associated with
each SWSP.
A monthly breakdown of depletions and replacement is shown on the attached Table 7.
Conditions of Approval
approve the proposed substitute water supply plan in accordance with Section 37 -90-
137(11), C.R.S., subject to the following conditions:
1. This SWSP shall be valid for the period of November 1, 2012 through February 28,
2013, unless otherwise revoked, modified, or superseded by decree. The plan may be
extended through October 31, 2013 if a copy of a sufficient lease is submitted to the
State Engineer's Office prior to February 1, 2013. If this plan will not be made absolute
by a water court action by the plan's expiration date, a renewal request must be
submitted to this office with the statutory fee (currently $257) by January 15, 2013 or
August 15, 2013 if the SWSP approval period is extended.
2. Well permit no. 61716 -F was obtained for the current use and exposed pond surface
area of the gravel pit in accordance with §37 -90- 137(2) and (11), C.R.S.
3. The total surface area of the groundwater exposed at the Shores Pit must not exceed 11
acres during the approval period of this SWSP resulting in an annual evaporative loss of
29.45 acre -feet.
4. The annual amount of water used at the operation shall not exceed 1.66 acre -feet for dust
control, 14.86 acre -feet of water lost with the product (505,000 tons) and the amount used
for concrete batching shall not exceed 12.89 acre -feet used in the production of 105,000
cubic yards of concrete.
5. Total consumption at the Shores Pit must not exceed the aforementioned amounts
unless an amendment is made to this plan.
6. Approval of this plan is for the purposes as stated herein. Any additional uses of this
water must first be approved by this office.
7. All diversions including releases back to the river shall be measured in a manner
acceptable to the water commissioner or division engineer. The Applicant shall install
and maintain such measuring devices as required by the water commissioner or division
engineer for operation of this SWSP.
8. All releases of replacement water must be sufficient to cover all out of priority depletions
and be made under the direction and /or approval of the water commissioner. The
replacement may be aggregated to maximize beneficial use. The water commissioner
and /or division engineer shall determine the rate and timing of an aggregated release.
