THIS LEASE is made and entered into tEis / ia' of
1998 , by and between the City of Lcvela: , Colc.rado, a 'o ';.ratio
home rule municipality ( "City" ) , whose address is 500 East Third
Street , Loveland, Colorado 80537, and Coulson Excavating Company,
a Colorado corporation ( "Lessee" ) , whose address is 3609 North
County Road 13 , Loveland, Colorado 80538 .
WHEREAS , the City owns certain water which, pursuant to the
water laws of the state of Colorado, may be used, re-used and
successively used to extinction ( the "Fully Consumable Water") ;
and
WHEREAS, the Lessee wishes to lease from the City the right
to use a portion of the City' s Fully Consumable Water; and
WHEREAS, the City is willing to lease' to Lessee a portion of
its Fully Consumable Water pursuant to certain terms and
conditions as set forth in this Lease ,
NOW, THEREFORE, in consideration of the mutual promises and
covenants contained herein and other good and valuable
consideration, the receipt of which is hereby acknowledged, the
parties agree as follows :
1 . The City hereby leases to the Lessee the right to
receive one hundred acre feet of the City ' s Fully Consumable
Water, as defined in paragraph 4 of this Lease, on an annual
basis . This Lease shall be for a term of twenty- five (25) years ,
ending on December 31 , 2022 . However, Lessee shall have the
option to renew this Lease for successive terms of twenty-five
years , which option shall terminate only if Lessee is in default
of its payment obligations under paragraphs 6 or 7 of this Lease
or if Lessee elects not to exercise its option to renew by giving
notice to the city pursuant to paragraph 12 of this Lease not
later than three (3) months prior to the end of any twenty-five
(2S) year term. In the event Lessee is not in default of its
payment obligations and elects to renew the Lease for any
successive twenty-five year period, Lessee shall not be required
to pay any additional amounts under this Lease for the right to
receive its allotted amount of the City' s Fully Consumable Water
as set forth above .
2 . The one hundred acre feet of Fully Consumable Water
which the Lessee shall be entitled to receive annually is
hereinafter referred to as the "Leased Water. " The parties
recognize that , simultaneously with the execution of this Lease, '
the City has leased the right to receive two hundred acre feet of
its Fully Consumable water to Loveland Ready Mix and that the
City may, in the future , lease additional portions of its Fully
Consumable Water to persons other than Lessee . The Lessee' s
right to receive one hundred acre feet of the City' s Fully
Consumable Water pursuant to this Lease shall be equal to the
right of Loveland Ready Mix to receive its two hundred acre feet
of Fully Consumable Water such that in the event less than three
hundred acre feet of Fully Consumable Water is available in any
year, Lessee and Loveland Ready Mix shall each be entitled to
receive a proportionate share of the available Fully Consumable
Water. The right of Lessee to receive one hundred acre feet of
the City' s Fully Consumable Water under this Lease shall be
deemed to be a first right relative to all others , such that in
the event the available Fully Consumable Water in any year is in
excess of three hundred acre feet but is not sufficient to meet
the needs of all persons holding leases of Fully Consumable
Water, Lessee shall receive up to its entire one hundred acre
feet allotment from the first three hundred acre feet of Fully
Consumable Water available .
3 . In consideration of the right to receive the Leased
Water, Lessee shall , upon execution of this Lease, pay City the
sum of Two Hundred Twenty Thousand and 00/100 ($ 220 , 000 . 00)
Dollars in certified funds . By entering into this Lease with the
Lessee, the City is and shall be under no obligation to file an
' application for a change of water rights or for a plan of
augmentation concerning the use of the Leased Water by the
Lessee .
The City shall not be responsible for the implementation of
any temporary substitute supply plan or augmentation plan
concerning the use of the Leased Water. The cost and expense of
any such proceeding shall be that of the Lessee . The City agrees
to furnish sufficient Leased Water so that , subject to the
provisions of this Agreement , the net usable first use or
subsequent use water obtained by the Lessee shall be 100 acre
feet . The City shall not be obligated to deliver Leased Water to
Lessee unless Lessee shall have first provided written notice to
the City that Leased Water will be required in a given year by
April 1 of the preceding year .
The City shall deliver the Leased Water under this Lease in
a total annual quantity as specified by the Lessee and at
specific monthly delivery times and in specific monthly
quantities according to the evaporation table , attached hereto as
Exhibit A, or as otherwise agreed by the City and the Lessee in
writing . In no event shall the monthly deliveries exceed the
monthly amounts shown on Exhibit A unless hereafter agreed in
writing by the City and the Lessee .
The Lessee shall not have the right to carryover from month
to month or from year to year any Leased Water which was
deliverable , but not requested for delivery, in a prior time
period. If the maximum allowable delivery under this Lease is
not requested by Lessee in any month, the right of Lessee to call
for the delivery of such water shall lapse and all such water
shall remain the sole property of the City.
4 . In 'supplying the Leased Water pursuant to this Lease,
the City may use any water, including, but not limited to the
following sources of water which may be used to extinction (the
" Fully Consumable Water" ) :
a . Native water from the Big Thompson River basin
which, when stored within the City' s reservoir
system, may be totally consumed pursuant to the
terms and conditions' of the Decree , for Change of
Water Rights for the City of Loveland, dated June
18 , 1985 , Case No. 82-CW-202A, Water Court
Division One, State of Colorado or subsequent
actions ; and
b. Water under an Allotment Contract with the
Municipal Sub-District of the Northern Colorado
Water Conservancy District (the "Northern
District" ) , commonly known as Windy Gap Water; and
c . Any water subsequently acquired by the City and
determined by Water Court Decree to be totally
consumable .
5 . The City shall have the right to deliver the Leased
water to Lessee from any of the sources of Fully Consumable
Water , at the City' s sole discretion, and shall have the right to
determine if any or all of the Leased Water shall be first use
water or subsequent use water. The City shall never be required
to deliver first use water, even if it is the only Fully
Consumable Water available to meet the terms of this Lease. In
the event the only water available to the City to meet the terms
of this Lease is first use Windy Gap Water and the City is
willing to deliver such first use water, the City shall notify
the Lessee prior to delivering such water and the Lessee shall
have the option to accept the first use Windy Gap Water and pay
the costs of delivering such water pursuant to the terms of
paragraph 6 of this Lease . In the event the Lessee refuses to
accept the delivery of the first use Windy Gap Water, the City
shall be deemed to have met its obligations under this Lease ,
until such time as a source of Fully Consumable Water, other than
first use Windy Gap Water, becomes available . In the event the
City is reasonably able to but fails to exercise its rights under
Case No . 62CW202A sufficient to meet the demands under this
Agreement, (unless the exercise of such rights would impair the
City' s ability to meet the normal domestic needs of the City) ,
and the only water available to the City to meet the terms of
this Lease is first use Windy Gap Water, the Lessee shall not be
required to pay the delivery charges provided in paragraphs S or
6 for the delivery of such first use Windy Gap Water .
6 . In the event the Lessee agrees to accept the delivery
of first use water from the City ' s allotment of Windy Gap Water,
Lessee shall pay to the City, the total costs of all pumping and
conveyance charges, plus any assessments and fees for
administrative, operating, maintenance and any other fees or
costs charged by the Sub-District for delivery of the water to
the City. ' The Lessee shall pay the City the total estimated costs
in advance , and the City shall not be obligated to deliver any
such water until it has received the full estimated payment . In
the event the estimated costs paid by the Lessee are less than
the actual costs incurred by the City in delivery of Windy •Gap
Water to the Lessee, Lessee shall pay the City any additional
amounts owed within thirty days of receipt of an invoice from the
City setting forth the amount owed. In the event the Lessee
shall fail to pay such additional amounts upon receipt of an
invoice from the City, the City shall have the right , in addition
to any other legal or equitable remedies it may have , to refuse
to deliver any Leased Water until such time as all additional
amounts owed pursuant to this paragraph have been paid in full .
In the event the estimated costs paid by the Lessee are greater
than the actual costs incurred by the City in delivery of Windy
Gap Water to the Lessee, the City shall refund any excess within
thirty days of the City' s receipt of an invoice from the Northern
District .
Lessee shall pay the City' s reasonable costs incurred
in administering the terms of this Lease . For the first five
years of this Lease, the administrative costs shall be One
Thousand and 0O/10O Dollars ($1 , 000 . 00) per year, payable in
advance . The City shall recalculate the reasonable administrative
costs every five years and inform the Lessee in writing of the
change at least thirty days prior to the start of the new five '
year period. In the event the Lessee does not require the
delivery of any of the Leased Water in a given year, there shall
be no administrative costs charged . The City shall invoice the
Lessee for the annual administrative costs in January of each
year and Lessee shall pay said costs within thirty days of the
invoice date . In the event the Lessee shall fail to pay its
accrued administrative costs in any year, the City shall have the
right, in addition to any other legal or equitable remedies it
may have, to refuse to deliver the Leased Water until such time
as all accrued administrative fees have been paid in full .
8 . At the option of the City, delivery of the Leased Water
shall be made at the City' s Waste Water Treatment Plant, 700
South noise Avenue, Loveland, CO, or at such other downstream
location or locations above the Lessee' s original point of need
as agreed by and between the Lessee and City in writing. Lessee
shall not unreasonably withhold its approval • of any request by
the City to move the point of delivery.
9 . Subject to the provisions of paragraph 5 , the City
shall only be obligated to deliver the Leased Water to the Lessee
if water meeting the requirements of this Lease is reasonably
available to the City. In the event of a drought or other
conditions , restrictions or emergency situations beyond the
control of the City which limit the City' s ability to receive or
deliver all or a portion of the Leased water to the Lessee, the
City shall be relieved of its obligations to deliver such water
under the terms of this Lease until such time as conditions
permit the City' s receipt and delivery of the Leased Water.
10 . The Lessee shall take the Leased Water AS IS and the
City makes no express or implied warranties of any kind or
nature , including the warranties of merchantability or fitness
for a particular purpose , concerning the water quality of the
Leased Water .
11 . In the event the Lessee wishes to assign, encumber or
exchange its rights to receive all or any portion of the Leased
Water not already used to satisfy a temporary substitute supply
plan or permanent augmentation decree to a third party, the City
shall have the first right of refusal to reacquire said rights .
In such event , Lessee shall notify the City in writing and shall
provide the City with a copy of the signed agreement between the
Lessee and the third party. The City shall have the right to
reacquire the water rights within ninety days from receipt of the
notice , by informing Lessee of its intent to exercise its first
right of refusal and by paying Lessee the contract price as set .
forth in the agreement between the Lessee and the third party. If
the City does not exercise its right of first refusal , the Lessee
may assign or transfer its rights to a third party, and the third
party shall be bound by all terms and conditions of this Lease,
including the obligation to allow the City the first right of
refusal on any transfer or assignment of the Leased Water, it
being the intent of this Lease that the City' s right of first
refusal shall apply to each and every transfer of the Leased
Water which may arise at any time during the existence of this or
any subsequent Lease . The right of first refusal set forth in
this paragraph shall not apply in the event the Lessee wishes to
assign, encumber or exchange its rights to receive all or any
portion of the Leased Water to a third party pursuant to an
exchange which is a transfer, sale or assignment of all or
substantially all of Lessee' s assets to said third party.
12 . After the City has increased the storage capacity of
Green Ridge Glade Reservoir to at least five thousand (5 , 000)
acre feet , and upon sufficient advance written notice so as to
permit the City to place appropriate orders for replacement
water, the Lessee may temporarily sub-lease the Leased Water or
portions thereof to third parties without activating the City' s
right of first refusal as set forth in paragraph 11, so long as
the length of the sub-lease term and the amounts and times of
discharge required by the Sub-lessee are acceptable to the City.
Any such lease arrangement shall firstsbe provided to the City
for its review and approval , which approval shall not be
unreasonably withheld.

1.0 INTRODUCTION
Coulson Excavating Co., Inc. (CEC) contracted Weiland, Inc. (WI) to complete
the well application/temporary substitute water supply plan (SWSP) for the Amen
Aggregate Resource (AAR). The AAR regular 112 permit was approved by the
Colorado Division of Reclamation Mining & Safety on December 5, 2019 (M-
2019-025). The project is currently in the process of seeking approval by Weld
County for Use by Special Review (USR) for mining sand & gravel. The project is
expected to break ground in April of 2020 and will begin by mining Cell 2 of 6 in
the first year. This plan covers April- 2020 through March 2021 . The source
replacement water source will be leased fully consumable water from the City of
Loveland.
1.1. LEGAL DESCRIPTION AND SITE LOCATION
The legal description of the site is: Two parcels of land in the south 1/2 of Section
19, T5N, R 67W of the 6th PM. A site location map is given in Figure 1- Site
Location Map.
1.2. JUSTIFICATION AND NEED
CEC provides sand gravel for construction of roads and development of the
infrastructure of Colorado. Their need is to extract gravel to keep up with their
demand for services. Additionally, there is a need to construct water storage
reservoirs to meet the ongoing water demands of CEC's operations.
1.3. PROJECT DESCRIPTION
Conventional dry mining methods shall be employed for the operation which
involves construction of dewatering trenches to drain the gravel deposit. The
dewatering trenches are pumped to a sediment pond on the surface which then
discharges to the Big Thompson River.
This plan covers extraction of sand & gravel from Cell 2, which is 17.5 acres and
is expected to last approximately 1 year. Mining will proceed from the north to the
south and will move from the lowest groundwater elevation to the highest. The
north 1/4 of Cell 2 will be opened up first and a sump will be dug for placement of
an electric submersible pump set on a pontoon float. The operation will then
proceed to the south and will successively add additional dewatering trenches.

2.0 OPERATIONAL WATER BALANCE
2.1. PREDICTED OPERATIONAL DEPLETIONS
2.1.1. Evaporative Losses
Evaporative losses will occur due to groundwater exposed in the network of
dewatering trenches, a sump constructed for the pump and a sediment pond.
Cell 2 has been divided into 4 equal areas surrounded by dewatering trenches.
The first 1/4 to be opened includes the sump and sediment pond. As mining
proceeds to the south, the trench lengths become cumulatively longer and are
subsequently added to the area of the first 1/4. Table 2.2.1-1 Exposed
Groundwater Area Calculation breaks down the quarterly area calculation by
trench length.
Table 2.1.1-1. Exposed Groundwater Area Calculation
Sump Area = 0.20 acres
Sediment Pond Area = 0.30 acres
Trench Width = 4 ft

The gross surface water evaporation calculation is based on a free water surface
evaporation of 40.4 inches year' (Farnsworth and Peck 1982). Historical climate
data shows mean temperature below 32 degrees for Dec-Jan, therefore ice cover
for those months prevents evaporation. Evaporative losses are offset by
applying effective precipitation credit (70% of precipitation) to the area of
exposed groundwater. Monthly precipitation values are an average of monthly
precipitation values from 1989-2017 at the NCWCD Loveland climate station.
AL1 Evaporative Loss Calculation gives the monthly calculation for predicted
net evaporative losses for April 2020 through March 2021. The total annual
evaporative loss from dewatering trenches, sump and sediment pond is predicted
to be 2.58 acre-ft.

Page 2 of 5
2.1.2. Mined Losses and Dust Control Losses
Water loss due to pore water extracted with the mined product has been
calculated based on 4% of the mined material weight as water. This calculation is
given in Al.2. Monthly Mined Water Extracted and Dust Control. The total
annual volume of water extracted with the mined material is predicted to be 11 .77
acre-ft.
Water will be appropriated for dust control by pumping from the sediment pond or
sump to water trucks. Periodic pumping for dust control will generally occur at <
0.5 c.f.s., however depletions are calculated based on monthly needs given in
Al.2. Monthly Mined Water Extracted and Dust Control. The total annual
volume of water extracted with the mined material is predicted to be 6.73 acre-ft.
2.2. LAGGED DEPLETIONS
Depletions from evaporative losses, mining and dust control have been summed
in Al.3. Total Net Water Loss / Replacement Requirement 2020-2021. Total
predicted depletions are then lagged in real time (non-steady state) utilizing the
IDS AWAS ver. 1 .5.85 program. The extent of the alluvial aquifer input is based
on the Atlas of Sand, Gravel & Quarry Aggregate Resources, Colorado Front
Range (GIS). Transmissivity was set to 40,000 g.p.d./ft. and is based on the
published Colorado DWR CDSS GIS. Total lagged depletions are given in Al.3
Total Net Water Loss / Replacement Requirement 2020-2021.
2.3. NET WATER DEPLETION
The net water loss per year can be written as:
(Monthly Evaporative Loss) + (Monthly Volume of Water Extracted) = (Net
Stream Depletion / Replacement)
The monthly sums of evaporative losses and water extracted have been lagged
utilizing the IDS-AWAS model as described above. The model was run to predict
actual monthly stream depletions as they occur (non-steady state).
The monthly water loss or potential injury to the Big Thompson River Total Net
Al.3 Water Loss / Replacement Requirement 2020-2021. The total annual net
depletion is predicted to be 20.02 acre-ft.
2.4. REPLACEMENT
Replacement water will come from fully consumable water owned by the City of
Loveland and Leased by CEC. Replacement water deliveries will occur at the
City's WWTP located at 700 S. Boise Ave, Loveland CO. A transit loss of 2% has
been assigned to the reach of the Big Thompson from the City's WWTP to the
ARR Site.

Monthly accounting will be submitted to the Division 1 office and will include
calculation of actual monthly depletions and replacements based on tons of
actual material mined and observed areas of exposed groundwater. A sample
accounting sheet is given in Al.6 Sample Accounting Worksheet.

AMEN AGGREGATE RESOURCE
1.0 ONSITE WASTE DISPOSAL PLAN
1.1 SOURCES OF WASTE
The proposed Amen Aggregate Resource Mining operation will generate small
amounts of solid waste from employee's food packaging and equipment
maintenance activities. All solid waste containers will have covers to prevent
transport by wind. Small onsite dumpsters will have adequate covers to protect
from wind transport.
Equipment maintenance will generate petroleum product waste and small
amounts of liquid hazardous waste (below small quantity generator as defined by
EPA). All petroleum products and hazardous materials will be stored in Hazmat
storage cabinets.
1.2 SOLID WASTE DISPOSAL
Solid waste will be removed from the site weekly by a local commercial waste
hauling company.
1.3 PETROLEUM PRODUCTS AND HAZARDOUS WASTE DISPOSAL
Petroleum products including engine waste oil, hydraulic fluid etc. generated from
equipment servicing will be hauled offsite by Coulson Excavating Co. (CEC)
service trucks to their main facility where Tristate picks up for recycling.
Hazardous materials will also be hauled offsite by CEC service trucks to their
main facility where they are picked up by tristate and recycled or disposed of in
the appropriate maner.
