INTRODUCTION
Broken Arrow Investments proposes to amend their current Derr Pit reclamation permit
located in the Northeast 1/4 of Section 4, Township 5 North. Range 65 West. Sixth P.M.
in Weld County, to include property to the north and west of the current permit area. The
overall property is bounded by Balsam Avenue on the west, East C Street / WCR 62 to
the north. WCR 43 to the east. and private property on the south. State Highway 263
(8th Street) is less than a quarter of a mile south of the subject property. The proposed
mining operation will extract gravel reserves from locations adjacent to man-made
structures. The rules and regulations of the Division of Reclamation. Mining, and Safety
(DRMS)require that any mining within a 200 foot setback of a man-made structure show
thorough engineering analysis that the proposed mining will not cause damage. The
accepted method of demonstrating this is through a slope stability analysis. This report
contains an overview of the prior geotechnical investigation results by Terracon and
Two Rivers Testing.. and the methodology used in the analysis of the mining slopes and
their estimated affects on all man-made structures. Recommendations regarding
acceptable setbacks from man-made structures have also been included.
OVERVIEW
The DRMS mining plan proposes that the property will be mined in 7 phases in 2 cells.
The reclamation plan, Exhibits E and F, propose the future use for this property to be a
slurry wall lined water storage reservoirs (2 cells) The mining will occur at 3H:1V
slopes. Concurrent reclamation is planned such that the reclamation embankment will
be constructed as the mining progresses. The reservoir cells will cover an estimated 68
surface acres when full. Actual surface area will depend on the final configuration of the
reservoir after reclamation is complete.
GEOTECHNICAL DATA
Preliminary geotechnical investigations have been performed by Terracon and Two
Rivers Testing. J&T Consulting. Inc. (JT) estimated soil strength parameters based on
the information from the geotechnical investigations. which was provided to JT by
Darwin Derr. and other stability analyses that have been performed on gravel mining
operations along the front range. Table 1, on the following page. represents a summary
of the soil strength parameters that were used in this stability analysis.

DESIGN ANALYSIS AND CRITERIA
The proposed mining slopes were analyzed using Clover Technologies Galena Slope
Stability Analysis System. version 7.0. Galena was designed to analyze the slope
stability of earth embankments subjected to several critical situations that may occur
during the life of the embankment. For this project, five cases were identified as critical
during the mining operation. Static and pseudo -static conditions were analyzed in each
case.
Pseudo -static peak acceleration factors (peak horizontal acceleration, or PHA) were
taken from USGS information for the western United States. The 2% probability of
exceedance in 50 years (the most conservative) was used. A peak acceleration factor of
0.10 x gravity was taken from this data. A conservative earthquake loading coefficient of
0.50 x PHA is often used for slope stability analyses (50% of PHA). We used an even
more conservative approach and used 70% of the PHA for this area for our earthquake
loading coefficient. Hence. 0.70 x 0.10 = 0.07.
All mining side slopes will be 3H:1 V.
Case 1 — West Property Line. The mining operation is adjacent to Balsam
Avenue and numerous utilities and structures on the west side of the site. The
mining depth was assumed to be 70 feet in this area based on bore log
information in the geotechnical reports. The proposed mining setback was set
200 feet from the existing ROW.
Case 2 - Proposed Oil/Gas Well in Northwest Corner of Site. The mining
operation is adjacent to proposed oil/gas wells in the northwest corner of the site
The mining depth was assumed to be 72 feet in this area based on bore log
information in the geotechnical reports. Mining activities will maintain a 200 foot
setback from the wells until they are completed. After they are completed the
proposed mining setback was set 100 feet from the wells.
Case 3 — North Property Line. The mining operation is adjacent to East C
Street/WCR 62 and numerous utilities and structures on the north side of the site.

The mining depth was assumed to be 70 feet in this area based on bore log
information in the geotechnical reports. The proposed mining setback was set
200 feet from the existing ROW.
Case 4 — East Property Line. The mining operation is adjacent to WCR and
numerous utilities and structures on the east side of the site. The mining depth
was assumed to be 64 feet in this area based on bore log information in the
geotechnical reports. The proposed mining setback was set 200 feet from the
existing ROW.
Case 4 — South Property Line. The mining operation is adjacent to private
property with a building. and an existing oil/gas well on the south side of the site.
The mining depth was assumed to be 52 feet in this area based on bore log
information in the geotechnical reports. The proposed mining setback was set
100 feet from the property line. and 150 feet from the building and oil/gas well.
The cross -sections located in Appendix B show the estimated phreatic surface
associated with each case as well as the geometry used in the mining/reclamation.
METHODOLOGY
The mining embankment configuration shown in the computer analysis represents the
estimated conditions for this site. If mining conditions differ from the estimated
conditions. the slope stability will need to be re-evaluated on a case by case basis. The
Bishop Method was used in the computer analysis for determining safety factors. The
procedure searches for circular shear failures and automatically searches for the lowest
safety factor. 8.000 separate failure surfaces were analyzed for each case. The required
minimum safety factors are based on the current standards used by the Colorado State
Engineer's Office (SEO) in evaluating embankment dams. and industry accepted
standards for the evaluation of temporary structures during construction.
SLOPE STABILITY RESULTS
The SEO requires minimum safety factors of 1.3 for static condition analyses and 1.0 for
pseudo -static (earthquake loading) condition analyses for Class I (high hazard)
embankment dams. This design criteria was used to establish the desired minimum
safety factors for this project and should be considered as highly conservative for
evaluating alluvial mining slopes. The calculated factors of safety are within the design
criteria specified for this project and can be considered indicators of the mining slope
performance under the various conditions. The results of the static condition and
pseudo -static condition slope stability analyses are presented in Table 2 and Table 3.

CONCLUSIONS AND RECOMMENDATIONS
Case 1 — The resulting safety factor of 2.55 exceeds the SEO minimum requirement of
1.30 for an embankment during construction. The resulting safety factor of 1.76 is above
the SEO minimum requirement of 1.0 for an embankment subject to earthquake
loading. Using a normal water surface elevation in the reservoir provides greater safety
factors. 3.64 under static loading and 2.00 under earthquake loads. The proposed
setback of 200 feet from the ROW is satisfactory.
Case 2 — The resulting safety factor of 2.00 exceeds the SEO minimum requirement of
1.30 for an embankment during construction. The resulting safety factor of 1.52 is above
the SEC minimum requirement of 1.0 for an embankment subject to earthquake
loading. Using a normal water surface elevation in the reservoir provides greater safety
factors, 2.64 under static loading and 1.66 under earthquake loads. The proposed
setback of 100 feet from the oil/gas wells is satisfactory.
Case 3 — The resulting safety factor of 2.55 exceeds the SEO minimum requirement of
1.30 for an embankment during construction. The resulting safety factor of 1.76 is above
the SEO minimum requirement of 1.0 for an embankment subject to earthquake
loading. Using a normal water surface elevation in the reservoir provides greater safety
factors. 3.64 under static loading and 2.00 under earthquake loads. The proposed
setback of 200 feet from the ROW is satisfactory.
Case 4 — The resulting safety factor of 2.63 exceeds the SEO minimum requirement of
1.30 for an embankment during construction. The resulting safety factor of 1.80 is above
the SEC minimum requirement of 1.0 for an embankment subject to earthquake
loading. Using a normal water surface elevation in the reservoir provides greater safety
factors, 3.69 under static loading and 2.01 under earthquake loads. The proposed
setback of 200 feet from the ROW is satisfactory.
Case 5 — The resulting safety factor of 2.26 exceeds the SEO minimum requirement of
1.30 for an embankment during construction. The resulting safety factor of 1.53 is above
the SEC minimum requirement of 1.0 for an embankment subject to earthquake
loading. Using a normal water surface elevation in the reservoir provides greater safety
factors. 3.71 under static loading and 2.02 under earthquake loads. The proposed
setback of 100 feet from the property line and 150 feet from the building and oil/gas well
is satisfactory.

The following recommendations for monitoring of slope stability should be followed:
1. A visual inspection of the excavated slopes should be done on a weekly basis for
the first 6 months of mining. This inspection should consist of walking the existing
ground and looking for any signs of stress cracks or other potential signs of slope
failure. Some minor sloughing of slopes is expected on any mine site The intent
of this inspection is to locate potential major slope failures that could potentially
extend back into a structure.
2. A visual inspection should be done after a major precipitation event that has
saturated the ground using the same procedures. A major precipitation event
would be defined as a storm that produces an intensity level reached once in 50
years on the average.
3. If a visual inspection detects signs of a potential slope failure. qualified personnel
should be contacted to evaluate and recommend remediation work to stabilize
the area.
4. If no visible signs of slope failure are detected within the first 6 months, then the
inspection period could be reduced to once per month or after every major
precipitation event.

INTRODUCTION
This report contains the results of our preliminary sand and gravel mineral evaluation for an
approximate 29 -acre parcel situated on the east side of Balsam Avenue, approximately '/z -mile
north of 8th Street, south of the Eaton Ditch in east Greeley, Colorado. The site is generally
located in the North 1/4 of Section 4, Township 5 North, Range 65 West of the 6th P.M., Weld
County, Colorado
The purpose of these services is to provide information and geotechnical engineering
recommendations relative to:
• subsurface soil and bedrock conditions
• groundwater conditions
• physical properties and estimated quantities of overburden and granular materials.
The conclusions and recommendations contained in this report are based upon the results of
our field and laboratory testing, engineering analyses, and experience with similar soil
conditions, and our understanding of the proposed project.
PROPOSED CONSTRUCTION
Based on the information provided, it is Terracon's understanding approximately 29 -acres of
land situated on the east side of Balsam Avenue, approximately '/2 mile north of 8'h Street
(Highway 263), south of the Eaton Ditch, presently being utilized as grazing and/or agricultural
property as well as for the Oil Industry, is to be considered for a future gravel pit for the mining
and extraction of sand and gravel reserves.
SITE EXPLORATION
The scope of the services performed for this project included a site reconnaissance by an
engineering geologist, a subsurface exploration program, limited laboratory testing and
engineering analysis.

Preliminary Sand and Gravel Mineral Evaluation
29 Acre Parcel - East of Balsam Avenue
Greeley, Weld County, Colorado
Project No. 20015242
Field Exploration
Terracon
A total of 7 test borings were drilled at the site during month of November of 2001. Terracon
drilled 3 test borings, (identified as Test Boring Nos 1, 2, and 3 shown on the enclosed Site
Plan, Figure 3) on November 5 and 6, 2001 to approximate depths of 75 to 90 -feet below
existing site grades. These 3 borings were advanced with a CME 75 truck -mounted drilling rig,
utilizing 4 -1/4 -inch inside diameter hollow stem augers.
After completing the first three borings, the client elected to obtain a specialized drill rig
capable of extending the test borings to the bedrock stratum by means of air rotary equipment
An air rotary rig from Layne -Western of Denver, Colorado, with assistance from the clients
conducted the remaining 4 test borings, (identified as Test Boring Nos B-1, B-2, B-3. and B-4
shown on the enclosed Site Plan, Figure 3) and logged the depths of the soil stratification to
bedrock. These test borings extended to approximate depths of 82 to 90 -feet below existing
site grades.
The borings were located in the field by measurements from existing site features at the
direction of Doug and Darwin Derr. After completing the related field services, the client hired
a land surveyor, which provided the appropriate boring locations and elevations as presented
in this report. Continuous lithologic logs of each boring drilled by Terracon (Test Boring Nos. 1,
2, and 3) were recorded by the engineering geologist during the drilling operations. At
selected intervals, samples of the subsurface materials from these test borings were taken by
driving a split -spoon sampler. Auger cutting samples from the air rotary Layne -Western Test
Boring Nos. B-1, B-2, B-3, and 6-4, were obtained by the client at selected intervals and were
delivered to Terracon's Greeley office for further evaluation and laboratory testing.
Penetration resistance measurements were obtained by driving the split -spoon into the
subsurface materials with a 140 -pound hammer falling 30 inches for the Terracon test borings
These penetration resistance values are a useful index to the consistency, relative density or
hardness of the materials encountered.
Groundwater measurements were made in Test Boring Nos. 1, 2, and 3 at the time of the initial
site exploration. Groundwater measurements were not recorded or provided to Terracon for
the Layne -Western borings prior to preparation of this report.
Laboratory Testing
All samples retrieved during the field exploration for Test Boring Nos. 1, 2, and 3 and the
composite samples collected by the client for the Layne -Western borings were returned to the
laboratory for observation by the project geotechnical engineer, and were classified in

accordance with the Unified Soil Classification System described in Appendix C. Samples of
bedrock were classified in accordance with the general notes for Bedrock Classification. At
that time. the field descriptions were confirmed or modified as necessary and an applicable
laboratory testing program was formulated to determine engineering properties of the
subsurface materials. Boring logs were prepared and are presented in Appendix A.
Selected soil samples were tested for the following engineering properties:
•
Water content
• Grain size distribution
Laboratory test results are presented in Appendix B. All laboratory tests were performed in
general accordance with the applicable ASTM, local or other accepted standards.
SITE CONDITIONS
The site is presently utilized as agricultural land and/or grazing land as well as by the Oil
Industry. The site is relatively flat exhibiting positive surface drainage in the southeast
direction. South of the site is vacant, undisturbed land typical in terrain as the subject site
West of the site is Balsam Avenue and north id the Eaton Ditch. The Cache La Poudre River
is situated approximately 1 -mile south of the site. An abandoned gravel pit is located directly
west of the subject site on the west side of Balsam Avenue.
SUBSURFACE CONDITIONS
Geology
The proposed area is located within the Colorado Piedmont section of the Great Plains
physiographic province. The Colorado Piedmont, formed during Late Tertiary and Early
Quaternary time (approximately 2,000,000 years ago), is a broad, erosional trench, which
separates the Southern Rocky Mountains from the High Plains. Structurally, the site lies along
the western flank of the Denver Basin. During the Late Mesozoic and Early Cenozoic Periods
(approximately 70,000,000 years ago), intense tectonic activity occurred, causing the uplifting
of the Front Range and associated downwarping of the Denver Basin to the east. Relatively
flat uplands and broad valleys characterize the present-day topography of the Colorado
Piedmont in this region. The site is underlain by the Cretaceous Pierre Formation at
approximate depths of 68 to greater than 90 -feet below existing site grades. The oedrock is

overlain by alluvial sands, gravels and clays of Pleistocene and/or Recent Age. The sand and
gravel represent an ancient Terrace of the Poudre River
Soil and Bedrock Conditions
The following describes the characteristics of the primary soil strata encountered at the site in
order of increasing depths, along with current groundwater conditions:
• Overburden Material - The overburden material consisted of slightly cohesive silty clayey
sand (SC) with trace amounts of gravel andior cobbles This material was generally
encountered at the surface and extended to depths of approximately 2-1/2 to 7 -1/2 -feet
below the surface. An approximate 3 to 7 -foot Sandy Lean Clay lens was encountered at
increased depths in Test Boring Nos. 1, 2. and 3 at approximately 47 to 56 -feet below site
grades. The silty clayey sand layers are relatively fine in nature, medium dense in relative
density and moist in -situ, while the day layers are medium stiff to stiff in consistency and
saturated.
• Silty Sand with Gravel and Cobbles: - Well Graded Sand with Gravel, Well Graded Sand
with Silt. Poorly Graded Sand with Gravel, Poorly Graded Gravel with Sand, Poorly Graded
Gravel with Silt and Sand, Well Graded Sand with Gravel, and Well Graded Gravel with
Sand — These strata were encountered in all borings at approximate depths of 2-1/2 to 7-
1/2 feet below the surface, and extended to the bedrock below in all but Test Boring Nos.
B-3, and B-4, where bedrock was not encountered to maximum depths of exploration, 90 -
feet. The sand and gravel stratum is poorly graded to well graded, loose to dense,
contains moderate amounts of silt, and is moist to wet in -situ. It is estimated that the
maximum size of gravel, and/or cobbles encountered with depth is typically less than 6 -
inches diameter.
• Weathered Claystone/Siltstone Bedrock - The bedrock stratum was encountered below the
sand and gravel layer at approximate depths 68 tc greater than 90 -feet feet below existing
site grades.
• Groundwater - Groundwater was encountered in Test Boring Nos. 1, 2, and 3 at
approximate depths of 4 to 4 -1/2 -feet below the surface at the time of the initial exploration.
Water measurements were not recorded for the Layne-Westem test borings. However, it
is anticipated that water levels would be relatively consistent at approximate depths of 4 to
6 -feet below site grades Water levels in this area are subject to change due to seasonal
variations and fluctuations in irrigation practices.

The stratification boundaries shown on the enclosed boring logs represent the approximate
locations of changes in soil types; in -situ, the transition of materials may be gradual.
According to the Soil Survey of Weld County, Colorado and as shown on the enclosed soil
conservation map. Figure 2 in Appendix A, the soils at the site consist of:

10 - Bankard sandy loam. 0 to 3 percent slopes. /4,- L, N -
)„vmr/A dc%
Field test results indicate that the overburden silty clayey sand layers are medium dense in
relative density. The coarse sand with gravel stratum varies from loose to dense in relative
density and the bedrock stratum varies from weathered to hard with depth.
CONCLUSIONS AND DISCUSSION
It is Terracon's understanding that the area under evaluation, approximately 29 -net acres,
based on plan line dimensions, is being considered as a potential gravel pit. Based on this
preliminary investigation and number of test borings drilled at the site, it is Terracon's opinion
the sand with gravel material encountered during the field exploration at various depths is
suitable for use as construction aggregate material.
The sand and gravel materials appear to satisfy the quality requirements to meet Colorado
Department of Transportation specifications for Class 1 Structure Backfill, Class 1 to 3
Aggregate Base Course and could be processed to obtain Class 6 and 7 Aggregate Base
Course if the course aggregate meets durability requirements. The gravel encountered
appears to be of good quality and contains durable rock fragments composed of igneous and
metamorphic rock fragments.
The overburden thickness encountered in the test borings ranges from approximately 2-1/2 to
11 -feet in thickness The underlying granular sand with gravel strata thicknesses encountered
during the drilling operations, (based on available information provided to Terracon for the
Layne -Western borings) ranges from approximately 57 to 84 -1/2 -feet. Based on these
thicknesses, plan line dimensions for the proposed 29 -acre parcel, and approximate areas of
potential mining operations, there are approximately_0.3_ million cubic yards of overburden
material that will v_e to be removed to obtain approximately 3.S million cubic yards of sand
and gravel material. Hence, the average ratio of sand and gravel volume to overburden
a

volume is approximately 11.6. The above referenced quantities are strictly estimated values
based upon average thickness of layers, average depth to bedrock and straight-line plan
dimensions. These estimates do not account for variations of thicknesses, actual areas of
mining and/or anticipated cut slopes.
Variations may be encountered in the field when gravel extraction/mining operations take
place. Safe distances should be kept from property lines, roads,. and waterways. Since the
sand and gravel strata was encountered below the groundwater, temporary dewatering of the
gravel pit or use of a drag line will be required to remove the sand and gravel material.
Excavation and possibly dewatering of the pit should be performed in such a manner as to
protect the adjacent properties, roads, railroads and waterways.
GENERAL COMMENTS
Variations in overburden and sand and gravel stratum thicknesses, the quantity of the sand
and gravel, as well as the soil and groundwater conditions, may exist between test borings.
These variations may not become evident until gravel/mining operations take place. Additional
test borings, test pits, and laboratory analysis may be required prior to the proposed
gravel/mining operations to more accurately evaluate the quantity and quality of the granular
materials encountered at the site.

Subsurface Exploration
SCOPE
This report presents the results of a subsurface exploration for a proposed sand
and gravel pit east of Greeley. The investigation was performed for the owners
to identify information that would assist in the installation of a slurry wall. The
investigation consisted of drilling 15 test borings, inserting water monitoring wells
for each boring and laboratory testing of samples obtained from these borings.
Information concerning the monitoring well installation is not included in our
scope of work, but was being provided by another consultant
The objectives of this study were to (1) evaluate the subsurface conditions at the
site relative to the proposed slurry wall construction (2) identify groundwater and
(3) identify bedrock depths.
The conclusions and recommendations presented in this report are based upon
analysis of field and laboratory data
SITE LOCATION AND DESCRIPTION
The site is located north of East 8'" Street and east of Balsam Ave in Part of
Section 4, Township 5 North. Range 65 West of the Sixth Principal Meridian,
Greeley. Colorado.
At the time of drilling, the site consisted of native grasses and weeds with an oil
battery located east of the west entrance to the site. The main location for the
sand and gravel mining had been leveled.
SITE EXPLORATION
The geotechnical field exploration was conducted October 16-18 and October
23-25, 2006 and consisted of drilling 15 test borings. The test borings are shown
on the Bore Location Plan enclosed in Appendix A and include visual
classifications of each soil, location of subsurface changes, and subsurface water
level measurements at the time of this investigation. The locations of the test
borings were determined by the client and field surveyed by the client. Table No.
1 provides a summary of the bore locations as provided by the client.
The borings were advanced using a 9" exterior/6" interior dual wall percussion
hammer drill pipe with continuous sampling done through a cyclone separator
mounted on a Drill Systems AP 1000 drilling rig. Samples of the subsoil were
obtained to determine an index of the soils with the results listed on the Summary
of Test Results noting the depth of specific soils, groundwater levels and bedrock
locations for each bore. A combination of hammer and reverse circulation drilling
were utilized to obtain samples. Samples for use in the laboratory were sealed in
the field and preserved at natural moisture content until time of testing.

LABORATORY TESTS AND EXAMINATIONS
Samples obtained from the test borings were subjected to testing and
observation in the laboratory to provide a sound basis for determining the
physical properties of the soils encountered. Moisture contents. percent passing
# 200 sieve, and the USCS classification were determined. A summary of the
test results and laboratory analysis can be found in Appendix B.
SUBSOIL AND GROUND WATER CONDITIONS
In summary, silty sand with gravel soils were encountered at the surface with
varying levels of sand, gravel and cobble intermixed with lenses of clay. Below
these soils weathered and competent bedrock soils existed to the depths
explored
1) Upper Soils. Varying levels of silty sand with gravel soils exist at the
surface to the bedrock encountered below Below these soils exist
varying levels of silt, sand. gravel and cobble mixed with intermittent
layers of silty sandy clay.
2) Lower Soils: Below the upper soils, varying types of weathered and
competent bedrock consisting of siltstone and claystone were present to
the depths explored Competent bedrock was present at depths ranging
from forty-five feet (45') to greater than one hundred twenty feet (120')
below existing surface.
3) Groundwater: Groundwater was encountered at depths ranging from
eight feet (8') to forty feet (40'). Water levels in this area are subject to
change due to seasonal variations and irrigation demands on and/or
adjacent to the property
Table No 2 summarizes the depth and elevation of the groundwater and
competent bedrock.

RECOMMENDATIONS AND DISCUSSION
Based upon the results of our investigation. we conclude that from a geotechnical
standpoint, the site is suitable for the proposed construction with the following
limitations listed below:
The slurry wall is proposed to be hammer driven with slurry injection. The
slurry wall should be installed a minimum of five feet (5') into competent
bedrock or until refusal occurs. Some leakage may still occur through the
siltstone bedrock stratum. A Geotechnical Engineer's representative
should be on site to verify competent bedrock is encountered.
GENERAL COMMENTS
This report has been prepared to aid in the evaluation of the property and to
assist the architect and/or engineer in the design of this project In the event any
changes in the design of the structures or their locations are planned, the
conclusions and recommendations contained in this report will not be considered
valid unless said changes are reviewed and conclusions of this report modified or
approved in writing by Two Rivers Testing, Inc., the geotechnical engineer of
record.
The professional judgments expressed in this report meet the standard care of
our profession. Every effort was made to provide comprehensive site coverage
through careful locations of the test borings, while keeping the site investigation
economically viable Variations in soil and ground water conditions between test
borings may be encountered during construction. In order to permit correlation
between the reported subsurface conditions and the actual conditions and
specifications as originally contemplated. it is recommended Two Rivers Testing,
Inc. be retained to perform continuous construction review during the slurry wall
installation. Two Rivers Testing, Inc. assumes no responsibility for compliance
with the recommendations included in this report unless they have been retained
to perform adequate on -site construction review during the course of
construction

RE: Loloff Pit - Slurry Wall Assessment
Dear Mr. York:
McGrane Water Engineering
Via email at: jcyork@j-tconsultinu.com
The Loloff gravel pit mine is located approximately 1 mile east of Greeley, Colorado in Section
4, Township 5 North, Range 67 West of the 6th principal meridian. The site is located
approximately %2 mile north of the Poudre River, approximately 5 miles upstream of the
confluence with the South Platte River. The pit is currently being mined under permit M-1985-
112 by Loloff Construction Company.
J&T Consulting, Inc. (JT) requested that McGrane Water Engineers, LLC. (MWE) determine the
hydrologic impacts of installing a slurry wall around the Loloff pit during reclamation.
Anticipated impacts include a rise in the water table on the up gradient side of the slurry wall
compared to predevelopment conditions and a decline in the water table on the down gradient
side. Water level increases to within 10 feet of the surface on the up gradient side of the pit
could flood existing structures such as basements or cause water logging and phreatophyte
growth. A decline in water levels on the down gradient side could reduce the aquifer saturated
thickness and well yields if pumping rates are already maximized.
Results
Using a MODFLOW model with reasonable boundary conditions and aquifer properties, MWE
determined that the maximum increase in water levels up gradient from the mine will be
approximately 2 feet, and the maximum decrease in water levels down gradient from the pit will
be approximately 2 feet. The average depth to groundwater for 79 wells with reported water
levels located within the model area (approximately a mile from the pit in all directions) is 16
feet. However, there are several wells located within the up gradient area of influence (greater
than 0.5 feet increase) that have reported water levels of less than 10 feet. Table 1 shows the
impacted wells located within the area of influence.

Three down gradient wells can be expected to experience a decline in water levels of
approximately 1 foot. Since well yield is proportional to the saturated thickness, we would
expect less than a 5% decrease in the maximum theoretical pumping rate of those wells. We do
not believe this is a significant impact.
Based on our modeling, eleven up gradient wells can be expected to have 0.5 to 2 foot increases
in water levels. Only one of those wells (Harrell Eldon) has a reported pre -mining water level
depth exceeding 10 feet. The rest of the wells either have reported depths to water of less than
10 feet or no recorded level so the depth remains "uncertain." If the recorded well locations and
depth to water are correct relative to the pit and if the wells are located near vulnerable structures
(homes with basements or excavations), those structures could be vulnerable to rising
groundwater resulting from the slurry wall.
Uncertainty
Whether future flooding or water logging will occur depend on numerous factors including: 1)
well location relative to the pit and slurry wall; 2) the location and depth of vulnerable structures
such as homes with basements; 3) the location, magnitude and timing of well pumping and
recharge from precipitation, agriculture, and canal seepage that could also affect water levels;
and 4) the location of existing drainage or canals that may intercept rising groundwater.
Therefore, there is considerable uncertainty whether there is a real and quantifiable risk of
significant impact.
Mitigation
Potential mitigation includes: 1) installing a drain around the slurry wall to minimize any
mounding or shadow effect to keep the aquifer at equilibrium 2) or moving or abandoning
Mr. J.C. York

structures with basements. JT has indicated that the installation of the drain around the slurry
wall at other similar gravel pit locations has been successful in mitigating the mounding and
shadow effects. The depth, location, and size of a drain will depend on the timing and location of
rising water and hydrologic properties of the aquifer.
Recommendations
We recommend:
1. Canvasing the area within the area of influence to confirm well locations and determine
whether any basements or structures could potentially be impacted;
2. Evaluating whether the existing monitoring well network is adequate to monitor
recovery after the slurry wall is installed, and installing additional wells if necessary;
3. If actual recovery appears to be excessive, utilize the model to evaluate drain locations
and designs (depths and size) to mitigate the situation. Intercepted groundwater could be
piped down gradient and recharged to prevent impacts to senior water rights.
Hydrologic Setting
Up to approximately 100 feet of saturated sand and gravel make up the alluvial aquifer located
within 2 miles of the Poudre River. The stratigraphy of the valley fill and particle size
distributions beneath the Poudre River observed in gravel pits was examined in detail by Langer
and Lindsey, 1999. The aquifer consists primarily of sand and gravel with minor fine-grained
interbeds. The aquifer was evaluated and modeled in detail by CDM-Smith, 2013 to support the
Colorado Water Conservation Board's (CWCB) South Platte Decision Support System (SPDSS).
Model Construction
MWE constructed a groundwater model of the alluvial aquifer north centered on the Loloff pit,
extending approximately one mile on either side. The model domain is 10,000 feet square on
each side, consisting of 100 rows and 100 columns with model 100 foot square model cells. The
model includes all of Sections 4 and 5 in Township 5 North, 65 West (6th PM), and the northern
half s of Sections 8 and 9. The model also includes the southern halls of Sections 31 and 32 in
Township 6 North, 65 West (6`h PM). Approximately 15,000 feet of the Poudre River crosses
the model from west to east. The river is hydraulically connected to the alluvial aquifer at all
times, and the groundwater gradient is from west to east. This is consistent with Figures 4-3 and
4-4 of the South Platte Alluvial groundwater model (CDM-Smith, 2013).
Well Data
Appendix A includes well data from 104 wells located within the model area. The database
consists of only active well permits with the exception of a few abandoned wells with usable
well data, none of which are included in Table 1. We removed shallow monitoring wells that
did not penetrate the alluvium, wells in excess of 119 feet deep thought to be completed in
bedrock, and all duplicate well permits. The depth of wells range from 21 to 119 feet and
averages 45 feet. The depth to water ranges from 2 to 46 feet and averages 16 feet. The reported
Mr. J.C. York
July 13, 2015
Page 4
well yields range from 10 to 1500 gpm and averages 244 gpm. The calculated saturated alluvial
thicknesses ranges from 7 to 82 feet and averages 31 feet. We used the 31 foot average thickness
to define the aquifer bottom and gradient (21 feet west to east) across the model. The average
aquifer thickness is consistent with the 37 foot thickness reported for the Loloff pit (Well permit
no. 77467 F) which was used in the radius of influence calculation (JT Construction, August 27,
2007).
Appendix B includes the following data plots: Figure B1 - Well Permit Numbers; Figure B2 —
Well Owner; Figure B3 — Well Depth; Figure B4 — Depth to Water; and Figure B5 — Saturated
Aquifer Thickness which support our model conceptualization and assumptions.
Aquifer Permeability
The aquifer hydraulic conductivity (K) is a measure of its permeability. Contoured K's obtained
from pumping tests reported for the State's South Platte Decision Support System (SPDSS Task
43.3, Figure 5C) groundwater modeling project (CDM-Smith, 2006) range from less than 250
ft/day to over 680 ft/day. Once the model was calibrated, the model area K averaged 600 to 650
ft/day (CDM-Smith, 2013, Figure 4-2). We assume an average model K of 625 ft/day.
The assume an average aquifer transmissivity in the model (145,000 gpd/ft) which is the product
of the hydraulic conductivity (625 ft/day) multiplied by the saturated thickness (31 ft). This is
consistent with published transmissivities for the Loloff pit model area by CDM-Smith (2006,
Figure 7a) and Hurr and Schneider, 1972.
Model Boundary Conditions
Model boundary conditions includes the Poudre River, aquifer subflow, and aquifer bottom. We
assigned the elevation of the Poudre River as 1 foot above the interpolated ground elevations
which are 4647 feet (msl) on the west end and 4626 feet (msl) on the east end of the model. The
river stage was assigned a foot above where the topographic elevation contour cross the Poudre
River and interpolated in between. We calculated model cell conductance (COND) as the
product of the streambed unit conductance (Ksb/m) times the wetted river area (length x width).
The average unit conductance obtained from SPDSS vertical permeability tests on the South
Platte tests is approximately 37 ft/day/ft. We assume that the average width of the Poudre River
is 50 feet. Therefore, model cell conductance is 185,000 ft"2/day (37 ft/day/ft * 50 ft * 100 ft).
Aquifer subflow in and out of the model were simulated using constant heads on the west and
east ends of the model set at the ground elevation contours at the Poudre river (4647 ft (msl) on
the west and 4626 ft (msl) on the east side. Constant head cells were spaced every 1000 feet in
the column 1 and every 100 feet along the east side of the model.
Model Mass Balance
Aquifer subflow in and out of the model was solved determined for the pre -pit steady state run.
Table 2 shows that river and aquifer inflows and outflows total 7.8 cfs and there is a net gain in
streamflow of 1.4 cfs within the model domain.

The net river gain of approximately 0.7 cfs per mile appears reasonable. We do not believe that
the pit slurry wall would significantly change the overall timing and location of historical river
gains.
Model Runs
We conducted two model runs to evaluate the hydrologic effects of installing a slurry wall
around the Loloff Pit. Run Lol_SS6 was meant to simulate the water table before the water
table was disturbed by pit excavation. Figure 1 shows the resulting water table gradient where it
crosses the Poudre River and through the outline of the future pit area and slurry wall.
In run Lol_SS7, the model cells within the pit area are turned off to not allow aquifer flow
through the pit which simulates the effect of proposed slurry wall. Figure 2 is the contoured
difference between the Post -Pit Run (Lol_SS7) — the Pre -Pit Run (Lol SS6). Positive values on
the left side of the pit reflect mounding and negative values on the right side reflect lower water
levels in the "shadow" of the pit. The maximum change in water levels is +1- 2 feet.
Model Sensitivity
The model results are insensitive to differences in hydraulic conductivities (K) since mound
height is inversely proportional to K and aquifer inflow is directly proportional to K. Therefore,
since the aquifer gradient and thickness are constant, an increase in K will cause a proportional
increase in model inflows which would increase mound height proportionally, but this does not
occur because the higher K causes a proportional decline in mound build-up.
Model results are insensitive to streambed leakance since the streambed is very permeable so
large amounts of water can move in and out of the stream in response to up -gradient mounding
and the down -gradient shadow effect. The model is sensitive to the area of the slurry wall, but
this is a fixed parameter. Therefore, the model is relatively insensitive to input parameters and
boundary conditions. We believe however that the model results in Table 1 are sensitive to: 1)
the relative location of wells and vulnerable structures such as basements to the up -gradient side
of the pit; 2) to the accuracy of reported predevelopment water level depths; and 3) to the timing,
location, and magnitude of various types of recharge such as precipitation and canal recharge.
Model Results, Uncertainty, Mitigation, and Recommendations
Results, uncertainty, mitigation, and recommendations are discussed earlier in the report.

backfilling and compacting the area with overburden or other suitable material prior to
excavating the next pie shaped area; provided, however, that in no event shall Gravel Company
mine within 90 feet of any Existing Well, Future Wells or any tanks, separators, dehydrators,
compressors and other equipment ("Production Facilities") and provided further that in no event
shall more than one quarter circle segment of the pie shape be excavated at any one time.
Excavation in the Existing Oil and Gas Operations Area and the Future Oil and Gas Operations
Areas will be coordinated with KMG in a mutually acceptable manner so as to avoid conflict
with KMG's oil and gas operations and to ensure there is an appropriate safety plan and interim
emergency procedures. Gravel Company will bear all costs associated with the mining
operation, including permanent or temporary rerouting and replacement of access roads, and
flowlines and utility lines in order to prevent unnecessary interruption of production from any
affected Existing Well or Future Wells, if any. In addition, Gravel Company and its successor
and assigns shall indemnify and hold KMG harmless from any and all damage, loss and liability,
including attorney's fees, incurred as a result of Gravel Company's operations in the Existing Oil
and Gas Operations Area or the Future Oil and Gas Operation Areas.
With the single exception of a slurry wall, Gravel Company will not locate any lot line,
building, or structure within either the Existing or Future Oil and Gas Operations Areas. Gravel
Company's slurry wall encroachment into the Existing or Future Oil and Gas Operations Area
shall not interfere with present or future KMG operations. Gravel Company will give ninety (90)
days notice prior to commencing operations in the Existing or Future Oil and Gas Operations
Area. Gravel Company shall complete such operations within fourteen days of commencement.
Gravel Company understands and acknowledges that the COGCC has rules and regulations that
apply to the distance between a wellhead and public roads, Production Facilities, building units
and surface property lines, among other things. In order to give full effect to the purposes of this
Agreement, Gravel Company hereby waives its right to object to the location of any of KMG's
facilities on the basis of setback requirements in the rules and regulations of the COGCC, as they
may be amended from time to time. Gravel Company further and similarly waives its right to
object to any other state or local setback requirements or other requirements or regulations that
are or become inconsistent with this Agreement or that would prohibit or interfere with the rights
of KMG, its successors and assigns, to explore for and produce the oil and gas in accordance
with this Agreement. KMG or its successors and assigns may cite the waiver in this paragraph in
order to obtain a location exception or variance under COGCC rules or from any other state or
local governmental body having jurisdiction. Gravel Company agrees not to object to the use of
the surface in the Existing Oil and Gas Operations Area and any Future Oil and Gas Operation
Areas so long as such use is consistent with this Agreement and so long as any such activity is
consistent with this Agreement and so long as such activities relate only to the production of oil
and gas from the mineral estate associated with lease listed in Exhibit B to include any
extensions, renewals or ratifications thereof and lands pooled therewith. Gravel Company will
provide KMG or its successors and assigns with whatever written support they may reasonably
require to obtain permits from the COGCC or any local jurisdiction.
3. GATHERING LINES AND FLOWLINES.
Subject to the limitations hereinafter described, KMG has a continuing right and
entitlement to own, operate, maintain, repair and replace all existing and future flowlines,

gathering lines and other pipelines that may be necessary or convenient to its operations on the
Property ("Pipelines"). The construction and burying of additional Pipelines shall be at the sole
cost and expense of KMG or its gas purchaser.
Although this Agreement is intended to confine the placement of the Pipelines to certain
specified locations within the Property, nothing herein shall be construed as a limitation on
KMG's ultimate right to make all necessary well connections to any Existing or Future Wells, so
long as such connections are made consistent with this Agreement. Specific locations have been
designated on Exhibits C, D-1 and D-2 for the location of the Pipelines ("Petroleum Pipeline
Easements"). The Petroleum Pipeline Easements shall be fifty feet (50') in width during
construction, installation, maintenance, repair or relocation operations and otherwise reduced to
twenty feet (20') in width for post -construction usage, being ten feet (10) on either side of the
pipeline.
Gravel Company's development plans anticipate that roadways will cross over
Existing and Future Pipelines. Gravel Company agrees to abide by the General Guidelines for
Design and Construction Activities On or Near Kerr- McGee Gathering LLC and Kerr -
McGee Rocky Mountain Corporation Pipelines and Related Facilities revised April 11,
2006 (Exhibit E). In particular, Gravel Company shall maintain a minimum of 48 inches and
not more than 72 inches of cover over all Pipelines during any of Gravel Company's operations
on the Property. When crossing KMG pipelines with trucks and lighter equipment, Gravel
Company will maintain a minimum of two feet and a maximum of six feet of dirt coverage, to
the existing cover over the pipeline. KMG may install and maintain markers on its Petroleum
Pipeline Easements. KMG shall mark its flowlines at all locations reasonably requested by
Gravel Company. Future Pipelines shall be located within the Petroleum Pipeline Easements
unless otherwise agreed upon between Surface Owner, Gravel Company and KMG. KMG
acknowledges that the Petroleum Pipeline Easements will be non-exclusive and agrees that it
will not object to its concurrent use by other oil and gas operators or utilities, as Surface Owner
may grant from time to time, so long as such other parties comply with the requirements of
Exhibit E.
Gravel Company will not allow any extraction to occur, commencing at the surface of the
original ground, closer than 25 feet from any Pipeline of KMG unless a soils stability report
prepared by an engineer licensed in the state of Colorado indicates that a lesser set back will be
adequate for preservation of the integrity of said pipeline and provided that upon completion of
such extraction Gravel Company shall back fill and level the area within 25 feet from any
Pipeline. Notwithstanding anything herein to the contrary, in no event shall Gravel Company
allow any extraction to occur, commencing at the surface of the original ground, closer than 15
feet from any Pipeline without KMG's prior written approval.

Gravel Company shall not allow any stockpile of soil to be placed over any Pipeline of
KMG.
When crossing KMG Pipelines with heavy equipment, like earth moving equipment,
Gravel Company will maintain a minimum of four feet and a maximum of six feet of dirt
coverage, in addition to the existing cover over the pipeline. When crossing KMG pipelines with
trucks and lighter equipment, Gravel Company will maintain a minimum of two feet and a
maximum of six feet of dirt coverage, to the existing cover over the pipeline.
The depth of cover over the KMG Pipelines shall not be reduced or drainage over KMG's
pipeline altered without KMG's written approval.
Any utility crossing must be a minimum of 18" inches vertical separation from KMG
Pipelines. Parallel utilities must maintain a minimum of ten -foot separation, unless KMG grants
a lesser distance of separation which grant shall not be unreasonably withheld. It would not be
unreasonable to withhold such consent due to reasonable safety or operational concerns. Gravel
Company will request that all utility companies contact KMG prior to laying lines parallel to
KMG pipelines.
Construction of any permanent structure within KMG's Petroleum Pipeline Easement is
not permitted. Planting of trees and shrubs is not permitted on KMG's Petroleum Pipeline
Easement.
4. ACCESS.
a. Gravel Company shall provide KMG with continuous access to the Existing Oil
and Gas Operations Area, the Future Oil and Gas Drilling Operation Areas, and the Future Oil
and Gas Operation Areas and the Petroleum Pipeline Easements. The access roads to be used by
KMG will either be those roads that currently are in place or those that are anticipated to be
constructed by KMG. KMG agrees to access the Property according to the routes depicted and
described on the attached Exhibit C, D-1 and D-2. When crossing irrigation structures with
heavy equipment, like earth moving equipment, KMG will maintain a minimum of four feet and
a maximum of six feet of dirt coverage, in addition to the existing cover over the structures.
When crossing irrigation structures with trucks and lighter equipment, KMG will maintain a
minimum of two feet and a maximum of six feet of dirt coverage, to the existing cover over the
structures.
Access to the Existing Oil and Gas Operations Area and the Future Oil and Gas
Operations Areas may be changed by mutual agreement of Gravel Company and KMG. Gravel
Company shall have the right to use any access roads.
Gravel Company shall maintain and keep any access jointly used by Gravel Company
and KMG in a condition and state of repair that serves the needs of Gravel Company. In the
event such joint access roads need to be improved in order to serve the needs of KMG, the
parties agree to coordinate any such improvements as may be required by KMG in order to
conduct its operations, provided that any such improvements shall be at KMG's sole cost and
expense. Neither KMG, nor Gravel Company shall unreasonably interfere with the use by the
other party of access roads.

Production Facilities by landscaping or other improvements, unless otherwise agreed upon
between Gravel Company and KMG. Gravel Company shall place temporary concrete barriers
around all Production Facilities as directed by KMG before any mining operations commence.
In no event shall Gravel Company mine within 90 feet of any Production Facilities or stockpile
mined materials within a radius of 50 feet of any Production Facilties.
6. NOTICE OF FUTURE OPERATIONS.
KMG shall provide at least seven (7) days prior written notice to Gravel Company of any
operations in connection with the reworking, fracturing, deepening or recompletion operation on
an Existing Well or Future Well; provided, however, that KMG shall provide at least thirty (30)
days prior written notice to Gravel Company of the initial drilling of any Future Well.
Regardless of the foregoing notice requirements, KMG shall have immediate access to any of its
facilities in the event of an emergency.
After receipt of the above notice, but not less than twenty (20) working days prior to

General Guidelines for Design and Construction Activities On or Near
Kerr- McGee Gathering LLC and Kerr - McGee Oil & Gas Onshore LP
Pipelines and Related Facilities
This list of design, construction and contractor requirements, including but not limited to the following, is for the design and
installation of foreign utilities or improvements on Kerr McGee Gathering LLC (KMG) right-of-way (ROW). These are not
intended to, nor do they waive or modify any rights KMG may have under existing easements or ROW agreements. For
information regarding KMG's rights and requirements as they pertain to the existing easements, please reference existing
easements and amendments documents. This list of requirements is applicable for KMG facilities on easements and in road
rights of ways only. Encroachments on fee property should be referred to the Land & ROW Department. Any reference to KMG
in the below requirements is meant to include and apply to any Kerr McGee entity.
Design
• KMG shall be provided sufficient prior notice of planned activities involving excavation, blasting, or any type of construction
on KMG's ROW or near its facilities. This is to determine and resolve any location, grade or encroachment problems and
allow for the protection of KMG's facilities and the general public. This prior notification is to be made before the actual
work is to take place.
• The encroaching entity shall provide KMG with a set of drawings for review and a set of final construction drawings
showing all aspects of the proposed facilities in the vicinity of KMG's ROW. The encroaching entity shall also provide a set
of "as -built drawings" and submit to KMG, showing the facilities in the vicinity of KMG's ROW upon completion of the work.
• Only facilities shown on drawings reviewed by KMG will be approved for installation on KMG's ROW. All drawing revisions
that affect facilities proposed to be placed on KMG's ROW must be approved by KMG in writing.
• KMG shall approve the design of all permanent road crossings.
• Any repair to surface facilities following future pipeline maintenance or repair work by KMG on it's "prior rights" ROW will be
at the expense of the developer or landowner. In addition, any repair to surface facilities following future pipeline
maintenance or repair work by KMG on replacement ROW granted to relocate KMG facilities will also be done at the
expense of the developer or landowner unless expressly addressed in surface use agreements and approved in writing by
KMG.
• The depth of cover over the KMG pipelines shall not be increased or reduced nor surface modified for drainage without
KMG's written approval.
• Construction of any permanent structure within KMG pipeline easement is not permitted without written approval by KMG.
• Planting of shrubs and trees is not permitted on KMG pipeline easement without written approval by KMG.
• Irrigation equipment i.e. backflow prevent devices, meters, valves, valve boxes, etc. shall not be located on KMG easement
without written approval by KMG.
• Foreign utility installations, lE, distribution gas, oil and gas gathering, water, electric, telephone, cable and sewer lines, etc.,
may cross perpendicular to KMG's pipeline within the ROW. provided that a minimum of eighteen inches (18") of vertical
clearance is maintained between KMG pipeline(s) and the foreign utility. Any installation by a foreign utility with less than
18" of vertical separation is not allowed without written approval by KMG. In no case will vertical separation be less than
12" whether written or not. Constant line elevations must be maintained across KMG's entire ROW width, gravity drain lines
are the only exception and must be approved in writing. Foreign line crossings below the KMG pipeline must be evaluated
by KMG to ensure that a significant length of the KMG line is not exposed and unsupported during construction. Foreign
line crossings above the KMG pipeline with less than 18" of clearance must be evaluated by KMG to ensure that additional
support is not necessary to prevent settling on top of the KMG natural gas pipeline. A KMG representative must be on site
during any crossing activities to verify clearance depths and to assure the integrity and support of the KMG facility. All
installations of foreign crossings done by boring and or jacking require the KMG facility to be exposed to verify clearances.
• Foreign utilities shall not run parallel to KMG pipelines within the KMG easement without written permission by KMG. A
minimum of 10.0 feet of horizontal separation must be maintained in parallel installations whether the foreign utility is

placed within the KMG easement or adjacent to the KMG easement. Any deviation from the 10.0' horizontal requirement
must be approved in writing by KMG and an "as built survey" provided to KMG after installation.
• The foreign utility should be advised that KMG maintains cathodic protection on its pipelines and facilities. The foreign
utility must coordinate their cathodic protection system with KMG's. At the request of KMG, foreign utilities shall install (or
allow to be installed) cathodic protection test leads at all crossings for the purposes of monitoring cathodic protection
interference. The KMG CP technician and the foreign utility CP technician shall perform post construction CP interference
testing. Interference issues shall be resolved by mutual agreement between foreign utility and KMG. All costs associated
with the correction of cathodic protection interference issues on KMG pipelines as a result of the foreign utility crossing
shall be borne by the foreign utility for a period of one year from date the foreign utility is put in service.
• The developer shall understand that KMG whether specifically required per federal law, or by company standard, will mark
the routing of it's underground facilities with aboveground pipeline markers and test leads and maintain those markers and
test leads. Markers will be installed at every point the pipeline route changes direction and adequate markers will be
installed on straight sections of pipeline to insure, in the sole opinion of KMG, the safety of the public, contractor, KMG
personnel and KMG facilities.
• On all foreign utility crossings and / or encroachments, metallic foreign lines shall be coated with a suitable pipe coating for
a distance of at least 10 feet on either side of the crossing.
• AC Electrical lines must be installed in conduit and properly insulated.
• On all foreign pipelines, DOT approved pipeline markers shall be installed so as to indicate the route of the foreign pipeline
across the KMG ROW.
• No power poles, light standards, etc. shall be installed in the KMG easement without written approval by KMG.
• KMG installs above ground appurtenances at various locations that are used in the operation of its facilities. Kerr McGee
will install protective enclosures at the above ground appurtenances to protect them from outside damage. The design and
placement of these above ground appurtenances and protective enclosures is done at KMG's sole discretion, and may
exceed any regulatory requirements.
Construction
• If KMG will be relocating KMG facilities for any entity, grading in the new KMG ROW shall be +1- 6 inches before KMG will
mobilize to complete the relocation. Final cover after the completion of the project will not be less than 48" nor more than
72". All cover that exceeds 72" or less than 48" will be approved in writing by KMG. Cover during all construction activities
will NEVER be less than 36" unless approved in writing and a KMG representative is on site during the time cover is
reduced.
• The entity requesting relocation shall survey top of pipe after installation but before backfill to determine proper final
elevation of KMG facilities. The entity requesting relocation is solely responsible for the final depth of cover over the
relocated KMG facility. Any deviation from cover requirements as outlined above will be corrected at the sole expense of
the entity requesting relocation.
• Contractors shall be advised of KMG's requirements and be contractually obligated to comply.
• The continued integrity of KMG's pipelines and the safety of all individuals in the area of proposed work near KMG's
facilities are of the utmost importance. Therefore, contractor must meet with KMG representatives prior to construction to
provide and receive notification listings for appropriate area operations and emergency personnel. KMG's on -site
representative will require discontinuation of any work that, in his or her opinion, endangers the operations or
safety of personnel, pipelines or facilities.
• The Contractor must expose all KMG pipelines prior to crossing to determine the exact alignment and depth of the

The use of probing rods for pipeline locating shall be performed by KMG representatives only, to prevent unnecessary
damage to the pipeline coating. A KMG representative shall do all line locating.
• Notification shall be given to KMG at least 72 hours before start of construction. A schedule of activities for the duration of
the project must be made available at that time to facilitate the scheduling of KMG's work site representative. Any
Contractor schedule changes shall be provided to KMG immediately.
• Heavy equipment will not be allowed to operate directly over KMG pipelines or in KMG ROW unless written approval is
obtained from KMG. Heavy equipment shall only be allowed to cross KMG pipelines at locations designated by KMG. Haul
roads will be constructed at all crossings. The haul roads will be constructed using lightweight equipment. The existing
depth of cover over the pipeline must be verified. Cover will be added such that a total of 8' of fill exists over the pipeline
and extends a minimum of 10' on each side of the pipeline. Depth of cover will then taper as required for equipment
access. Steel plates may be used for load dissipation only if approved in writing by KMG.
• Contractor shall comply with all precautionary measures required by KMG,at it's sole discretion to protect its pipelines.
When inclement weather exists, provisions must be made to compensate for soil displacement due to subsidence of tires.
• Excavating or grading which might result in erosion or which could render the KMG ROW inaccessible shall not be
permitted unless the contractor agrees to restore the area to its original condition and provide protection to KMG's facility.
At no time will cover be reduced to less than 36" without written approval by KMG and a KMG representative on site.

Re: Flood Hazard Development Permit application (FHDP-545) — Dust & Dirt Excavating Derr Gravel Pit
Dear Mr. Derr.
The Weld County Public Works Department has reviewed the requested Flood Hazard Development Permit
(FHDP) application for the proposed Riverbend gravel pit and associated office complex. The current FHDP
application can be conditionally approved at this time based on the comments and requirements below.
Please note, this permit is only for the gravel mining operation. It does not include provisions for the future
scale and scale house. If a scale and scale house are to be added at a future date and the facilities are located
in the floodplain. this FHDP shall be amended and an elevation certificate shall be submitted.

Public Works Department
A FHDP application was submitted and received on November 20. 2008 and includes the following
documentation:
1. A FHDP application (page 6) signed by Douglas D Derr and date stamped November 20. 2008.
2. A FHDP report signed. dated. and stamped by J.C. York. P.E. No. 36846 and dated November 15,
2008.
3. Maps showing the location of the portable processing facility and stockpiles in relation to the Poudre
River floodplain.
4. A copy of the HEC-RAS model output.
5. A copy of the quit claim deed.
The following information was added to the FHDP file:
1. A copy of the FEMA FIRMette showing the approximate location of the gravel pit property.
2. A copy of the Preliminary FEMA FIRM showing the approximate location of the gravel pit property.
3. A copy of the GIS map showing the location of the gravel pit property in relation to the Poudre River
floodplain
The proposed Derr gravel pit will be located in the 100 -year floodplain of the Cache La Poudre River north of
State Highway 263 and east of and adjacent to Balsam Avenue. The project site is located on Flood Insurance
Rate Map (FIRM) Panel Numbers 080266-0629C, dated September 28, 1982. It is also located on the
Preliminary FIRM Panel Number 080266-1541E, dated June 10, 2005. All Special Flood Hazard Areas
(SFHAs) for the project site are published on the current effective FIRM as Zone A. indicating that published
base flood elevations (BFEs) are not determined. All SFHAs for the project site are published on the
Preliminary FIRM as Zone AE indicating that published BFEs have been determined. All FIRMs are prepared,
distributed, managed, and revised by the Federal Emergency Management Agency (FEMA).
FEMA requires the use of best available information for determining the floodway and BFEs in locations where
areas where they have not been identified. The Army Corps of Engineers (Corps) and Greeley have prepared
a model of the Cache La Poudre River which contains BFE determinations. The Corps model extends from just
upstream of WCR 23 to the mouth of the Cache La Poudre River and includes the area of the proposed Derr
gravel pit. The Corps model was done using the 1929 NVGD vertical datum.
The J&T Consulting model submitted in support of this application utilized the Corps model to determine the
impact that the proposed gravel pit would have on the Cache La Poudre River Floodplain. J&T Consulting
modified the Corps model in cross section 13 of the Split Left stream geometry. According to discussions with
J&T Consulting. it is expected that the temporary material stockpiles will be located at various locations in the
pit as mining progress. The revised Corps model shows an obstruction approximately 10 feet tall by 205 feet
wide in the above mentioned cross section. The obstruction represents the location of the stockpile in the worst
case scenario in the 100 -year floodplain. The model shows that the temporary stockpiles are not expected to
impact the floodplain. The water surface elevations determined by the revised HEC-RAS model were
converted to the 1988 NAVD vertical datum. According to the Preliminary FIRM dated June 10. 2005 and the
cross section elevations shown in the revised model, the depth of water across the majority of the property is
expected to be between 1 and 2 feet during the 100 -year flooding event.
Please refer to the Requirements section of this memorandum for further requests.
Environmental Health
Environmental Health Services has reviewed this proposal. The application indicates that an Individual Sewage
Disposal System (ISDS) will not be constructed in the floodplain. Upon review of our records for the identified
parcel number. there is not an ISDS associated with the parcel. As there are no water wells or ISDS that will be
located in the floodway or floodplain this department has no concern with this request.
REQUIREMENTS:
Planning Department
1. Stockpiling of any material and long term parking of non -operational vehicles in the Floodplain is not
permitted due to the highly erosional nature of placement of said material and vehicles in this location.
