Rocky Ford Oitch credits will first be applied to depletions at the Rocky Ford Pit, with excess credits carried
down stream and applied to depletions at the Lamar East Pit site if advanced arrangements have been made to allow
pass-through of these credits through John Martin Reservoir to the point of depletion for the Lamar East Pit.
Replacement using LAWMA shares will be first applied at the Lamar East Pit site. Depletions at each site that cannot
be covered by ditch credits or LAWMA shares, and depletions caused by elimination of return flows due to dry-up
under the 2 ditches, will be replaced using releases of the Pueblo water from Clear Creek Reservoir (or from another
reservoir delivered as if released from Clear Creek Reservoir). The operational scenario giving monthly depletions and
replacements is detailed on your attached table. Depletions at the Lamar East Pit site from November through March
shall be added to the Post-1985 depletions LAWMA is responsible for at the stateline. PBWW water that meets the
criteria for delivery to the Offset Account in John Martin Reservoir can by provided to compensate LAWMA for the
additional winter depletion replacement as necessary.
Valco has requested that it be allowed to de-water excavations at each of these pits as operations require. At
the Rocky Ford East pit, water pumped from the de-watered excavation will be discharged into another excavation
resulting in ground water recharge. Both the excavation that is being de-watered and the excavation that serves as
recharge are within the MLRD permit boundary for the Rocky Ford East pit and are located similar distances from the
Arkansas River, resulting in no net affect on the river. Water pumped from excavations within the Canon City East and
Lamar East pits will be routed through an adjacent excavation, but will reach the river as surface flow, You contend
that the excavations being de-watered at these two sites are sufficiently close to the Arkansas River that lagged
stream depletions are not of concern. We believe that this will be the case so long as the de-watered pits are within
100 feet of the river. Valco must track total exposed surface area from all areas of exposed ground water and ground
water recharge pits and must account for all evaporative losses accordingly.
The State and Division Engineers have reviewed the plan and the adequacy of each source of water provided
for use as augmentation water, including, where necessary, the historical consumptive use of each water right, and
return flows from diversion of waters imported into the Arkansas River Basin or other fully consumable waters
proposed for use as augmentation water. In accordance with Section 25-8-202(7), C.R.S. and Senate Bill 89-181
Rules and Regulations adopted on February 4, 1992, the State Engineer has determined that subject to the terms and
conditions below, the replacement supply is of a quality to meet the requirements of use to senior appropriators.
This substitute water supply plan is hereby approved pursuant to Section 37-90-137(11), C.R.S., subject to the
following conditions:
1. This SWSP shall be valid for the period of June 1, 2007 through May 31, 2009, unless otherwise revoked,
modified, or superseded by decree. Should an additional SWSP be requested, such renewal request must be
submitted to this office with the statutory fee of $257 at least 45 days prior to the expiration date of this plan.
Operation of this plan since the date of the last approval letter is also adopted by this plan approval.
2. No more than 30.1 acres (14.7 acres of post-1981 exposure) of ground water may be exposed at the Canon
City East Pit, nor more than 47.3 acres (29.9 acres of post-1981 exposure) of ground water may be exposed
at the Rocky Ford East Pi! nor more than 35.4 acres (22.2 acres of post-1981 exposure) may be exposed at
the Lamar East Pit during this plan year without first obtaining an amendment to the plan. The above acreage
totals include any surface areas in ponds to which de-watering water is delivered. Documentation of pond sizes
may be required by the Division Engineer in the form of an aerial photo evaluation or survey by a Professional
Land Surveyor during the plan year or in years covered by subsequent renewals of this plan.
3. All diversions for concrete botching and any dust suppression done at the sites must be measured in accordance
with the "Amendments to Rules Governing the Measurement of Tributary Ground Water Diversions Located in
the Arkansas River Basin". Monthly meter readings from Well Id 1205640 and 1705985 are to be provided to
the Division Engineer (e-mail to Div2Ground.WaterCdtstate.co.usl. Reported readings from Valco should
include the Welt td, each recording digit and the meter multiplier.
4. Subject to approval by the Division Engineer, the Applicant may lease or purchase additional replacement
water from the sources approved in this plan. The Applicant must provide a copy of a tease/purchase
agreement to the State Engineer's Office and the Division Engineer for use of such additional replacement
water. Should any of the leases expire prior to the expiration of this plan, lease renewals must be obtained
and submitted within 2 weeks of their expiration.
5. Approval of this SWSP is for the purposes stated herein. The State Engineer's Office must first approve any
additional uses for which the water may be used. The replacement water, which is the subject of this SWSP,
