TYPE OF APPLICATION: Limited Impact Review GENERAL PROJECT DESCRIPTION The Northern Parachute Valley is seeing more activity from drilling, gathering, processing which is placing more
demand on the communications infrastructure supporting this valley. Presently, Parachute Valley communication network runs between the Sage Brush Gas Plant to the Administration Building
with other communication sites such as Greasewood, TR 41-35, Mt. Callahan, and Gas Plant in between these locations. See attached diagram. The existing communication tower is situated
on a COGG well pad TR 41 -35 and is a critical location for the Williams' network since other locations are dependent on this tower to receive and relay information up and down the valley.
The existing tower lacks the necessary height to provide adequate line of sight (LOS) in all directions. Therefore, Williams wishes to replace the existing 20 foot tower and supporting
infrastructure with an 80 foot tower along with a new communication building, and propane powered back-up generator. The new tower site will be situated to the west and overlap a portion
of the old tower location. The proposed tower will maintain a smaller footprint by its building selection and placement of the solar panels and wind generator on the building. The proposed
tower will be free-standing and the tower and foundation will be designed to meet specific requirements for weight and wind loads. Access to the site will be by Garden Gulch Road. For
a Communication Facility being reviewed through Limited Impact Review the following information applies: I. REGULATORY PROVISIONS APPLICANT IS REQUIRED TO ADDRESS: • Garfield County

Business Problem/Opportunity Statement Additional business activity in the Northern Parachute Valley from drilling, gathering, processing, and control and ') operations are placing more
demand on the communications infrastructure supporting Northern Parachute Valley. ) Drilling in the Highlands continues into areas where there is poor radio coverage required for well
control and the collection of data (SCADA). In the Trail Ridge and Ryan Gulch areas drilling and the migration to the new CygNet SCADA Host system are driving expansion and rework of
the existing infrastructure. To satisfy William's drilling activities in the Trail Ridge area 2 new tower locations: TRll-1 and TR34-16 are planned for Spring/2011. The Ryan Gulch area
also has plans for 2 new locations: RG 23-35 and RG 13-1 for spring 2011. Communication Tower location is critical. Towers must be located in proximity of the wells being drilled so
that the Master radios on these towers can communicate with the RTUs located on the drilling pads. These towers, in turn must have a clean Line of Sight (LOS) to a point further upstream,
ideally a point (node) on a backhaul segment of the network to pass along data. For the well locations and towers mentioned above, these "backhaul node" locations are TR41-35 for TR
and Greasewood for RG. The diagram below shows the main segments of the "backhaul "network Williams has in place in the Parachute Valley. Sagebrush, the furthest point in the North West
section connects via Greasewood, TR 41-35, Mt Callahan and Gas Plant to the Admin Building. The Admin Building is where the network connects to Williams Corporate Network. William's
SCADA systems are located in the Operations Center, close to the Admin Building. The TR and RG Master locations are also shown in the diagram. One can see where they connect into Greasewood
and TR 41-35 respectively to carry traffic down the valley to the host systems locations at the Operations Center. Williams TR 41-35 Communications Infrastructure Page 2
The Communications Tower location at TR 41-35 is a critical location for the Williams backhaul network and the two TR towers as each of these depend on this location to receive and relay
traffic to Mt Callahan, Gas Plant and Admin Building. ;TR 41-35 lacks the necessary tower height to provide adequate line of sight (LOS) in all directions. Williams has initiated a project
to replace the existing 20' tower and supporting infrastructure at this location with an 80' tower, new communications building and propane powered back-up generator. To determine the
required height for a new tower at TR 41-35 Williams performed an engineering study. The series of diagrams below represent the path profiles from this study showing the paths for the
radio shots between Master tower locations in TR and TR 41-35. Also shown is the path profile between the Greasewood location (north) for which the RG Masters feed, and TR 41-35. This
is important as TR 41-35 is the southern connection point for Greasewood, and as such is critical for communications to anything north of this point on the Network. These profiles, first
showing the current path for the existing 20' tower @TR 41-35, and then the profile for the proposed 80' tower, show the need for an 80' tower at TR 41-35. The diagrams depict the path
the micro-wave radio signal travels between the end points. This path is represented by the red line. The blue concentric ellipsoid represents the Fresnel Zone. This shows the radiation
path of the radio waves Williams TR 41-35 Communications Infrastructure Page 3 ) )
as they travel away from the originating point. If obstructed the energy from these waves reflect back to the source. This causes interference, and when they are out of phase, they actually
reduce or cancel out the signal. This works much ) the same as noise reducing headset s, reducing receive signal strength. The Fresnel Zone should be un-obstructed. TR 41-35 to TR 34-16
