HomeMy WebLinkAbout1.03 Impact statementIMPACT STATEMENT
The site selection of the proposed facility took into account the current uses
of the land surrounding the site, minimizing the visual impact created by the
facility, traffic impact to roads, proximity to residences, and the potential for
success of reclamation. Alternate locations were studied prior to the
selection of the proposed site, but were found to either not meet with the
criteria listed above or had other environmental or operational issues.
Construction of the water storage and evaporation facility will ultimately
reduce the volume and impact from truck traffic on County roads 300 and
304.
The facility will be in continuous use and operation 24 hours per day, on a
year round basis. However, the majority of activities associated with the
facility will occur during typical, daylight working hours. Garfield County
Road 304 is the primary access to the general producing area, but is
currently a non - maintain road. EnCana will assume the responsibility of
maintenance of the road and right -of -way.
During peak usage times, the facility is expected to require an average of
approximately 6 water tanker trips per day into and out of the facility. The
majority of these trips will be on existing and future on -lease roads that
already or will in the future serve natural gas wells and operations within the
area. Water trucks will operate primarily during daylight hours and will be
traveling to and from well locations.
The electric driven pump is expected to emanate low -level noise and
minimal amounts of vibration. The pump building will aid in mitigating the
noise and vibration emitted from the pump and associated equipment. The
sound level of noise emanating from the facility will not exceed the 75
decibel maximum set forth in Colorado Revised Statute 25 -12 -103. Given
the remote location of the planned facility, noise will not be a nuisance to
area residents. The vibration, if any, should be localized to a small area
immediately surrounding the pump. If, in the unlikely event, nuisance noise,
vibration, or odors are emanated by the facility, additional measures will be
taken to control them.
The facility is designed to protect ground water and surface water resources.
The storage pond will be lined with a 60 millimeter impermeable high-
density polyethylene (HDPE) liner placed on top of a felt skid free pad to
prevent the poly liner from moving. Preparation of the dirt pad surface
beneath the liner will include tilling and raking the soil to at least an 18 inch
rock free surface. Compaction of the pond berms will meet or exceed 95%
Proctor Density. Compaction test will be conducted by a certified, 3rd party
inspection company.
The storage pond will be surrounded by a 6 foot field fence (wood post with
wire mesh panels). The fence includes steel gates for personnel access. The
gates will typically remain closed at all times to prevent unauthorized entry.
The adjacent property characteristics and surrounding land uses are such that
a visible barrier fence should not be necessary. Facility signage will include
the company name, address, and 24 -hour emergency contact numbers.
The High Mesa Water Storage and Evaporation Facility will occupy about
two acres of the EnCana owned 40 acre parcel. Colorado Department of
Wildlife maps indicate that the site is located on winter rangeland for mule
deer and elk. This type of facility is by nature incompatible with continued
wildlife access therefore wildlife will be excluded by wildlife -proof fencing.
The limited size of the facility will not block wildlife migration routes. The
water stored at the site is not expected to be an attraction or threat to
waterfowl, but a deterrence system will be installed if waterfowl usage does
occur.
All equipment will be painted to match the color of the surrounding terrain
as closely as possible. Visual impact to the area will be minimal due to the
placement and limited amount of surface equipment used at the site.
Electrical power will be the only public utility used by the facility.
The anticipated life of the facility is approximately 20 years. Reclamation of
the facility is outlined in the "Reclamation Plan" section of this packet.
Reclamation will be bonded under the State permit application.
