Re: Application for Substitute Supply Plan for NCCI Pit No. 1
Dear Mr. Rollin:
As requested, we are submitting to you our report for the Northern Colorado Constructors, Inc. (NCCI)
Pit No. 1 substitute water supply plan.
PROJECT DESCRIPTION
The NCCI Pit No. 1 is located on the northwest corner of the intersection of Weld County Roads 18
and 25 (East One-Half of Section 24, Township 2 North, Range 67 West, 6th Principal Meridian, Weld
County, Colorado). This location is approximately one mile west of Highway 85 and 1.5 miles north
of Fort Lupton. A vicinity map is attached as Figure 1. and Figure 2 provides an aerial image of the
site. The permit boundary encompasses 102 acres of which 70 acres will be disturbed by the mining
operations.
The site is currently covered with approximately 27 acres of non-jurisdictional wetlands; 11 acres of
irrigated pasture grass; and about 64 acres of non-irrigated non-wetland area. There are portions of
the site that are under water year-round and much of the area is subirrigated from the South Platte
alluvium and seepage from the Meadow Island Ditch No. 1 which appears to flow year-round. All of
the area that is under water year-round will not be disturbed. During the mining operations,
groundwater will be exposed in the dewatering trench- collection basin, and the wash water recycle
pond.
Mining is scheduled to begin in early 2002 and take about 10 years to complete. The maximum annual
production is estimated to be 350,000 tons of material. Reclamation of the site should be complete by
the year 2013. The reclamation plan for the site is lined water storage ponds with a total water surface
area of approximately 68 acres.
The mining plan is divided into seven phases: mining will begin at Phase 1 and proceed through Phase
7. Each phase is expected to require about 1.5 years to complete. Lining of each pitipond will
commence immediately following the completion of mining in each phase. The pivpond in Mining
Phase 1 will be lined prior to the excavation to groundwater in phase 2. This plan covers only the two-
year period associated with the mining of Phases 1 and 2.

reclamation plan.
DEPLETIONS
Water depletions during the mining operations include:
► Evaporation from the dewatering trench, collection basin, and wash water recycle pond:
► Water lost through dust control; and
► Water lost through material mined and hauled offsite.
Evaporation
Evaporation losses are based on the NOAA Technical Report NWS 33, Evaporation Atlas for the
Contiguous 48 United States. For this location, annual gross evaporation is approximately 44.0 inches.
Monthly evaporation is calculated based on the percentage set forth by the guidelines from the Office
of the State Engineer. Precipitation is estimated using the Climatological Data published by NOAA.
Annual precipitation at this site was assumed to be equal to that at the nearest gage station: Fort
— Lupton for the period 1950 to 1975 and Brighton for the period 1976 to 1999. The resulting long term
(1950 through 1999) average annual precipitation at the NCCI Pit No. 1 site was estimated at 13.00
inches, based upon the available data for both stations. The net evaporation at the site is computed as
— the gross evaporation minus the effective precipitation, which is computed as 70 percent of the total
precipitation. The calculated net evaporation is therefore 34.90 inches, or 2.908 acre-feet per acre.
For the mining condition, groundwater will be exposed in the dewatering trench, the collection basin,
and the wash water recycling pond. Water in the trench will flow by gravity to the collection basin
before being pumped out of the pit. The dewatering trench will be approximately 3,300 feet long and
three feet wide, resulting in 0.23 acres of exposed water surface. The collection basin will be oval
shaped with a length of 70 feet and a width of 25 feet. resulting in 0.03 acres of exposed water surface.
The wash water recycling pond will be oval with dimensions of approximately 200 feet long and 100
feet wide, resulting in 0.36 acres of open water surface. The total open water surface is estimated to be
0.62 acres. Annual evaporative consumptive use from the mining condition is calculated as the
product of net evaporation and exposed water surface area resulting in 1.82 acre-feet (see Table 1).
Water Lost Through Dust Control
An estimated 3,000 gallons of water per day will be used for dust control. It is estimated that dust
control will be required six days per week during nine months of the year(February through October),
or 235 days per year. This results in a total consumptive use of 2.16 acre-feet per year.
Water Lost with the Material Hauled Offsite
The maximum annual production of material from the pit is estimated at 350,000 tons per year. The
moisture content of the material hauled from the site is assumed to be four percent by weight. Based
Rnc
Mr. Ken Rollin

upon these assumptions, water lost with the mined product will total 10.30 acre-feet per year,
calculated as shown below:
350,000 tons/year x 2,000 lbs/ton x 4% =28,000,000 lbs
28,000.000 lbs/62.4 lbs per cubic foot/43,560 square feet per acre= 10.30 acre-feet per year
It is estimated that 10 percent of the total annual production will be mined during December, January
and February,with the balance being removed uniformly through the remainder of the year. Thus,
monthly water loss from transporting the material would be approximately(values in acre-feet):

Total Depletions During Mining
_ The total depletions during the mining of NCCI Pit No. 1 are estimated to be 14.3 acre-feet per year as
shown on Table 2. Total projected annual depletions include 1.82 acre-feet resulting from
evaporation. 2.16 acre-feet from dust control, and 10.30 acre-feet resulting from material hauled
offsite.
REPLACEMENT WATER
Replacement water for depletions associated with mining operations will consist of leased water from
Consolidated Mutual Water Company. In addition,NCCI owns three shares of Lupton-Meadows
Ditch (Certificate No. 0632, Appendix E) that historically irrigated 11 acres of pasture grass located in
the southeastern portion of the permitted mining area. The consumptive use credit associated with
these ditch shares owned by NCCI will be used as replacement water for this plan.
The Lupton-Meadows Ditch includes a 52.12 percent interest within the Lupton-Bottom Ditch rights.
The Lupton-Bottom Ditch is decreed for 47.7 cfs with an adjudication date of April 28, 1883 and an
appropriation date of May 15, 1863. The first enlargement was decreed on the same date for 92.87 cfs
with an appropriation date of September 15, 1873. The combined decreed capacity of the Lupton-
Bottom Ditch is therefore 140.47 cfs, of which the Lupton-Meadows Ditch is entitled to 73.27 cfs
(52.12 percent). NCCI owns three shares out of a total of 4,084 outstanding shares within the Lupton-
- Meadows Ditch. Table 3 summarizes the total Lupton-Meadows Ditch diversions and the average pro-
rata ditch diversions associated with the three shares owned by NCCI and dedicated to this plan. The
table shows the NCCI's pro-rata interest has historically yielded an average of 7.04 acre-feet per year.
Historically. the southeastern portion of the permitted mining area included pasture grass irrigated by
the subject three shares of Lupton-Meadows Ditch. The irrigation requirement for this crop was
RMC

determined by using the Modified Blaney-Criddle equation. Appendix B contains the historical
consumptive use data for this site.
It has been determined that groundwater subirrigation of the pasture grass occurs at this site.
Exploratory drilling recently performed upon the property has indicated an average water table depth
of approximately three feet in the vicinity of the irrigated pasture grass. The figure included in
Appendix C from Evapotranspiration and Agronomic Responses in Formerly Irrigated Mountain
Meadows shows that with a groundwater depth of three feet, 36 percent of the total irrigation
requirement is met by subirrigation. As shown in Table 4, the total potential consumptive use for the
11 acres of pasture grass is 18.48 acre-feet per year of which 6.65 acre-feet is met by groundwater.
The remaining irrigation potential consumptive use is 11.83 acre-feet per year.
Table 5 summarizes the historical irrigation analysis (water budget) for site. An assumed ditch loss of
10 percent is assumed for determining the net farm headgate deliveries. Additionally, a maximum
farm efficiency of 55 percent is assumed. The actual consumptive use is estimated as the lesser of the
irrigation potential consumptive use as shown on Table 4 and the amount of water available for
consumption (Table 5, Column 2).
Return Flow Obligations
Historically, farm irrigation has caused depletions to the South Platte River which are not
instantaneous. The actual potential consumptive use was subtracted from the farm headgate diversions
to determine the return flow at the site. Of the total return flow, it was assumed that 20 percent is the
result of surface runoff that returns to the river without lagged effects and 80 percent returns through
the groundwater with lagging effects. The delayed return flows through groundwater were entered
into the State's Stream Depletion Model based upon Glover techniques to determine the lagged flows
realized at the river.
The center of the historically irrigated acreage is approximately 2,800 feet from the South Platte River.
Pump test records from the Colorado Groundwater, Circular No. 11 produced by the USGS were used
to determine an adopted transmissivity of 140,000 gpd/ft. A value of 0.20 was adopted for the specific
yield, which is typical for an alluvial aquifer. The impermeable boundary for the alluvial aquifer was
estimated to be 10,600 feet from the river, based upon USGS topographic mapping. Results from the
Stream Depletion Model are summarized in Appendix D. The delayed return of deep percolation. as
shown on Table 5, was estimated based the results of the Stream Depletion Model.
Since the gravel mining operations are located approximately 4,500 feet away from the South Platte
River, a stream depletions analysis (Appendix D) using the State Engineer's Office stream depletion
model was performed to determine the impact upon river. Shown below are the estimated stream
depletions in the South Platte River associated with the mining operations:

Table 6 provides a summary of the replacement obligations associated with historical irrigation
— practices and future mining operations. The net replacement obligation is estimated to be 10.8 acre-
feet per year, as shown in Table 6, Column 5. Consolidated Mutual Water Company will provide
replacement water credit into the South Platte River from the Metro Wastewater Treatment Plant on
— behalf of NCCI in accordance with the monthly delivery schedule provided in Table 7. A conveyance
loss of 15 percent has been assumed for the 30-mile reach between the point of delivery at the Metro
Wastewater Treatment Plant to the point of depletion on the South Platte River. NCCI will lease more
— water if actual mining depletions are larger than projected. A copy of the water lease agreement
between Consolidated Mutual Water Company and NCCI will be provided to the State Engineer's
Office as soon as both parties have signed the lease. Appendix F includes a copy of the lease
agreement.
OPERATION OF PLAN
An accounting form is shown on Table 8. The form provides for monthly tabulation of evaporative
depletions and water used in the mining process. Each month, Consolidated Mutual Water Company
will provide replacement water in the amount as shown on Table 7. If the actual replacement
requirement requires adjustment, Consolidated Mutual Water Company will be notified and the
releases will be adjusted accordingly. Historical river headgate diversions in the amount of 7.0 acre-
feet per year will be continue throughout the operation of this plan. The river diversions, less 10
percent ditch losses, will be measured back to the river.
LOCAL WELL IMPACTS
A tabulation of groundwater wells located in the vicinity of the NCCI Pit No.1 site will be provided
with the well permit application for this gravel mining operation. NCCI will seek to obtain the consent
of all well owners with wells located within 600 feet of the mine, and understands that consent or a
hearing is required prior to issuance of the gravel pit well permit.
CONCLUSIONS AND RECOMMENDATIONS
The consumptive use of water associated with all phases of mining, throughout the 10-year
operational life, is estimated at 14.3 acre-feet per year.

Weed Management Plan
Site Location
The NCCI Pit #1 is a 102 acre parcel at the northwest corner of the intersection of Weld
County Roads 25 and 18 two miles northwest of Fort Lupton, Colorado. It is in the East '/2
of the Southeast 1/4 of Section 24 Township 2 North, Range 67 West. The land is currently
used for pasture of cattle. The proposed use is for a gravel pit.
Objective
To control undesirable plants in Weld County and that occur on the property, a weed control
plan is proposed. Plants listed in the Weld County Code Chapter 15 —Vegetation and found
on the property include: Scotch Thistle, Musk Thistle and possibly Canada Thistle.
Management Techniques
The methods of control will be cultural, mechanical, biological and chemical. These methods
are defined as follows:
Cultural - The method or management practices encourage the growth of desirable plant to
crowd out or discourage the growth of noxious weeds.
Mechanical - The method and practices physically disrupt the growth of the plant and include
mowing, tilling, burning, flooding, mulching, hoeing or hand pulling.
Biological—The use of organisms such as sheep, goats, cattle, insects and plant diseases to
disrupt plant growth of undesirable plants.
Chemical—The use of herbicides or plant regulators to disrupt the growth of undesirable
plants.
The site has a mix of wetlands and flat pasture areas. There were no noxious weed found in
the wetland areas. The flat areas where there is disturbance of the surface Scotch Thistle and
Musk Thistle were found. There is also the possibility of some Canada Thistle.
Wed management for the site will be as follows:
Scotch and Musk Thistle:
The site will be treated with herbicide during the rosette stage. Herbicide may be used to the
bud stage. Mowing will be used, as needed, during the growing season to prevent the plants
from going to seed.
Canada Thistle
The site will be treated with herbicide during the rosette stage to the bud stage. Mowing will
be used during the growing season to prevent the plants from going to seed.
Should other noxious weeds be found on the site they will be managed in a manner as outlined
in the Guidelines For Noxious Weed Management Plans as provided by the Weld County
Department of Public Works.
This plan was prepared from information and help provided by Mr. Ron Broda.
WELL MONITORING PLAN
FOR
NORTHERN COLORADO CONSTRUCTORS
NCCI PIT #1
Northern Colorado Constructors (NCCI) has applied for a Use by Special Review Permit to
mine sand and gravel on a parcel in the east half of the south east one quarter of Section 24,
Township 2 North, Range 67 West in Weld County, Colorado. The mining will require the de-
watering of the site of the mining and the primary source of water in the area is the alluvial
aquifer and is produced by shallow wells. Because of the concern of the surrounding well
owner as to the effect of the de-watering on their wells Northern Colorado Constructors will
implement the following well monitoring program to determine the effect, if any, of the de-
watering on the surrounding wells.
1. Install monitoring wells on the mining site boundary as shown on the attached site
plan.
2. Monitor the level of the water in the wells monthly and monitor the quality of the
water yearly. The monitoring data will be available to the surrounding well owners
and the Weld County Planning Department.
3. If the surrounding well owners will agree NCCI will monitor the water level and
quality of the wells on their property on the same schedule. NCCI will require
written approval from the property owner to enter the property and test the wells.
4. All monitoring will be at NCCI's expense.
5. If damage to a well is determined to be caused by NCCI, steps will be taken to
mitigate the damage by the method which is best suited to the situation. These
methods include grout walls, re-drilling of the well, directing pumped water to
recharge the well, provide another source of water or cease pumping the mining
site.
