Divide Road Water Facility. Garfield County. Colorado Dear Mr. Putnam. Yeh and Associates had previously conducted a Geotechnical Investigation at the proposed Divide Road Water Facility
in Garfield County. Colorado. Our report. under our project number 212-011. dated March 7. 2012. was reviewed prior to the issuance of this letter. The major geotechnical considerations
for this site are as follows. Based on exploratory drilling and proposed grading. cuts in hard to very hard sandstone. occasionally cemented. may be encountered. We believe the sandstone
material can be excavated by conventional construction equipment. but may need to be excavated by means of heavy ripping and/or blasting. Site specific geotechnical recommendations are
presented in our previous report. We believe that there are no geotechnical constraints that would preclude construction at this site. If our geotechnical recommendations are considered
in the design and construction. we believe the site is suitable for the proposed facility. If you have questions or need additional information. please call us at 970-384-1500. Sincerely.

ASSOC I ATES O\.OLSSON \ GEOLOGIC AND SOIL HAZARDS REPORT Introduction Encana Oil and Gas (USA) Inc. has proposed a Divide Road Water Facility to be located approximately 20 miles northwest
of the Town of Parachute, west of Middle Fork Parachute Creek and just south of local road 401, in Garfield County, Colorado. This proposed water facility will be located in Section
26, Township 4 South, Range 96 West, of the Sixth Principal Meridian. The vicinity of this proposed Divide Road Water Facility is shown on a map provided in Figure V-1 . The proposed
project lies adjacent to areas already undergoing natural gas development by Encana Oil and Gas (USA) Inc. The natural gas resources that are being developed are underlying the main
body of the Eocene age Uinta Formation (Tu) shown in Figure G-1. Geology The proposed project is located centrally within the Piceance Basin; an irregularly-shaped elongated basin formed
by tectonic forces that downwarped the earth's crust as a result of the uplift of the Colorado Rocky Mountains. Areas on all sides of the Piceance Basin have been uplifted by these same
tectonic forces. Structural Geology The Piceance Basin is the major structural geologic feature in the region. It is bound to the east by the Grand Hogback monocline, the White River
Uplift to the northeast, the Gunnison Uplift to the south, the Uncompahgre Uplift to the southwest, the Douglas Creek Arch to the westnorthwest, and the axial basin uplift to the north
(Grout and Verbeek, 1992). The Grand Hogback monocline is a sinuous feature comprised of Upper Cretaceous age bedrock of the Mesaverde Group, which includes the Williams Fork Formation
and the underlying Mancos Shale. The Grand Hogback forms part of the boundary between two major physiographic provinces, the Colorado Plateau and the Rocky Mountain foreland. The Grand
Hogback bends abruptly to the north of the Gibson Gulch Quadrangle. The strata along the west to southwest-facing, steep limb of the monocline typically dip basinward, dipping at an
angle of 45° or even overturned in some areas (Grout and Verbeek, 1992). A series of west-northwest trending, broad, gentle anticlines and synclines, are present within the Piceance
Basin to the west of the Grand Hogback. The Wolf Creek Anticline and the Divide Creek Anticline are the Encana Oil and Gas (USA) Inc. Divide Road Water Facility August 2012 1 Olsson
Associates Grand Junction, CO OA Project # 012-0400
two closest of these structures. The axis of the Divide Creek anticline crosses the southwestern part of the Gibson Gulch Quadrangle. There are a total of eight joint sets, or fracture-pattern
trends, that have been mapped in the Wasatch and Mesaverde Group bedrock units in the area (Grout and Verbeek, 1992). These jOint sets are the result of structural deformation of these
sedimentary rock units through geologic time. Surficial Geology This part of the Uinta Formation consists of siltstone, marlstone and sandstone with some minor oil shale, limestone and
conglomeratic sandstone. The majority of the plateau top in the central Roan Plateau area is underlain by this part of the Uinta Formation. The cliffs at the edges of the plateau to
the east and west of the location are comprised of the Parachute Creek Member of the Green River Formation and consist of oil shale, sandstone and mudstone. The rocks of the Uintah Formation
are the parent material for the soils that occur at this location. Soils According to information prepared by the Natural Resources Conservation Service (NRCS) Soil Survey, soils in
these sections have been mapped as Irigul channery loam, (36), Northwater loam (48), and the Parachute-Rhone loams (53) (Fig.S-1). A copy of a NCRS Custom Soil Resource Report for the
project site has been provided. Irigul channery loam (36), soils are developed on 9 to 50 percent slopes and consist of welldrained soil in land setting of mountainsides and ridges.
Elevations range from 7,800 feet to 8,700 feet above mean sea level. The parent material of this soil is Marl and/or residuum weathered from sandstone. The Northwater loam (48) is developed
on 15 to 65 percent slopes at elevations of 7,600 to 8,400 feet and found in landform settings of mountainsides. The parent material of this soil is residuum weathered from sedimentary
rock. The Parachute-Rhone loams (53) soils are developed on 5 to 30 percent slopes and consist of well-drained soils on mountainsides and ridges at elevations of 7,600 to 8,600 feet.
These soils are Marl and/or residuum weathered from sandstone. According to the soils map provided in figure S-1 shows that the proposed Divide Road Water Facility is located on the
Parachute-Rhone loams (53). With this, and in reference to the Table -Corrosion of Concrete within the NRCS soils report, states that the corrosion of concrete is low for this area.
As for the rate of corrosion of concrete it is based mainly on the sulfate and sodium content, texture, moisture content, and acidity of the soil. According to the Table-Corrosion of
Steel within the NRCS soils report it states that the corrosion rate of steel is moderate. The rate of corrosion of uncoated steel is related to such factors as soil moisture, particle-size
distribution, acidity, and electrical conductivity of the soil. Further investigation may be required on as needed basis. Encana Oil and Gas (USA) Inc. Divide Road Water Facility August

Geologic Hazards According to the information provided by Garfield County, Colorado -GIS Department on slope hazards the proposed facility is located outside the boundary of the geologic
study. In Figure F-1, the floodplain data provided by Garfield County, Colorado -GIS Department shows that the proposed facility does not lie within a floodplain area. Conclusions and
Summary Stormwater controls and best management practices should take into consideration the geology and soil types present at this location. These engineering controls and practices
should be used temporarily and permanently to divert stormwater away from the construction areas and to prevent additional weight which could trigger a debris flow or landslide. Pits
are required to be lined by COGCC rules, but pit liners may also prevent water infiltration into unconsolidated sediments which could trigger slope failure. Pits and catchment basins
should be sited and designed so as not to add weight to potentially unstable areas. Olsson Associates appreciates the opportunity to provide this information to Encana Oil and Gas (USA)
Inc. pertaining to the assessment of geologic and soil hazards associated with the proposed Divide Road Water Facility in Garfield County, Colorado. Olsson can conduct field work to
assist with the site specific assessments of the proposed project to determine the degree to which these hazards may affect the specific location. Sincerely, Olsson Associates, INC.

INTRODUCTION & OBJECTIVE This Traffic Analysis summarizes the impacts associated with the proposed Divide Road Water Treatment Facility (DRWTF). DRWTF will be accessed via Garfield County
Road 215 (Parachute Creek Road) to Encana's North Parachute Ranch gate, and then via a private road network. No new or improved accesses onto a County or State roadway will be required
or are being proposed. The site is approximately 16 miles northwest of the Town of Parachute. DRWTF will be constructed, operated, and reclaimed in three phases. These phases include:
• Facility Construction (1 0-11 months) • Operation (20 years) • Reclamation (21 days) EXISTING NETWORK DRWTF will be accessed from County Road 215 and an existing private roadway. According
to the guidelines in the Colorado Department of Transportation (CDOT) State Highway Access Code, this road is classified as a Rural Highway (R-B). CR 215 is a two lane asphalt roadway
with gravel shoulders. The road has a posted speed limit of 35 mph. TRAFFIC PROJECTIONS Given the lack of data regarding traffic growth for this area, a conservative growth rate of 3%
was assumed. This rate was applied to the existing counts to obtain background traffic for the forecast years of 2013 and 2033. These planning horizon years were chosen as they correspond
with the construction and reclamation phases, respectively. Due to the anticipated low traffic volumes, the lifespan of the DRWTF will have minimal impact, if any, to the existing road
system. This facility is being constructed to allow collection, storage and distribution of produced water and recycling of that water for well completion activities in the nearby area.
This will result in an overall reduction in traffic along CR 215 by reducing the number of trucks needed to haul water to and from the area surrounding the proposed water facility to
locations that are now being used for water supply and water disposal. Heavy vehicles will only be utilized for construction, condensate collection, repairs, and reclamation. Light vehicles
will visit the site routinely to insure the DRWTF is operating safely. Approximately 10 trucks a month will visit the site each month to remove condensate. Basic Traffic Analysis Page

EXISTING PARCELS Current land uses on the surrounding parcels are primarily natural gas development with rural residential and agricultural use. The majority of existing traffic is related
to natural gas development activities. An existing two-track roadway exists which will primarily serve the existing site. No new access to state highways or railroad crossings will be
required. RECOMMENDATIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to be significant. The worst-case scenario
during operation of the facility is that there would be a minimal, short-term increase in truck traffic. The expected scenario would be a decrease in water hauling truck traffic along
CR-215. Based on the results of the analysis, no mitigation is recommended for the DRWTF. The additional traffic from the DRWTF will not significantly increase the existing low levels
of traffic. Based on this analysis, no roadway improvements or turn lanes are anticipated to be required to support this project. Basic Traffic Analysis Page 3
