Trout Valley Ranch SWSP June 19, 2017
Plan ID 5900 Page 4 of 7
It is the responsibility of the Applicant to ensure that replacement water is provided in
time, place, and amount. Replacements may be provided downstream of the point of
depletion but upstream of the calling water right. The Applicant must notify the District 23
and District 80 water commissioners at least 48 hours prior to making replacement deliveries.
The applicant is required to obtain the water commissioner’s approval on a daily basis or as
required by the water commissioner. Our office has previously expressed to North Fork
Associates, LLC and Mountain Mutual Reservoir Company the need for measurement devices,
particularly on Deer Creek and the North Fork of the South Platte, to allow administration of
these water rights. Our office will continue to work with North Fork Associates, LLC and
Mountain Mutual Reservoir Company to ensure that replacement water can be adequately
measured and accounted for.

Long Term Augmentation

In accordance with the letter dated April 30, 2010 from the Colorado Division of
Reclamation, Mining, and Safety (“DRMS”), all sand and gravel mining operators must comply
with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations
for the protection of water resources. The April 30, 2010 letter from DRMS (copy attached)
requires that you provide information to DRMS to demonstrate you can replace long term
injurious stream depletions that result from mining related exposure of ground water. Upon
completion of mining operations and reclamation, there will be no permanent water exposure
and the site will be reclaimed to rangeland. In accordance with approach number 3, a total
bond amount of $415,073, which includes the cost of backfilling the pond(s), has been set by
DRMS and obtained by the Applicant.

Conditions of Approval

I hereby approve the proposed SWSP in accordance with § 37-90-137(11), C.R.S.,
subject to the following conditions:

1. This SWSP is approved with the effective date of June 19, 2017 and shall be valid
through October 31, 2017 unless otherwise revoked or superseded by decree. The
expiration date may be extended through May 31, 2018, if an extension of the current
lease (extension until at least May 31, 2018) is provided to this office prior to October
31, 2017. The expiration date may be extended through May 31, 2019, if an
extension of the lease (extension until at least May 31, 2019) is provided to this office
prior to October 31, 2017 (or October 31, 2018 if previously extended). If this
SWSP will not be made absolute by a water court action by the SWSP expiration date,
a renewal request must be submitted to this office with the statutory fee
(currently $257) no later than August 1, 2017 (April 1, 2018 if extended through May
31, 2018; April 1, 2019 if extended through May 31, 2019).
2. A well permit must be obtained for the current use and exposed surface area of the

this plan. Any application will be evaluated subsequent to approval of this SWSP. The
provisions of § 37-90-137(2), C.R.S., prohibit the issuance of a permit for a well to be
located within 600 feet of any existing well, unless the State Engineer finds that
circumstances so warrant after a hearing in accordance with the procedural rules in
2CCR402-5. The hearing will be waived if you are able to obtain statements from the
