The proposed Redwillow Pipeline will transport dehydrated sour gas

Proposed Redwillow Project
Project Description Highlights
• The proposed Redwillow Pipeline will transport dehydrated sour gas from
the Tumbler Ridge area. The pipeline will be up to 323.9 mm diameter (12
inch), and will be designed to transport 1,982,000 cubic metres per day
(70 MMscfd) of natural gas containing up to 30% hydrogen sulphide
(H2S).
• The proposed Redwillow Pipeline includes approximately 150 km of
pipeline from southwest of Tumbler Ridge, BC connecting with the
SemCAMS operated Northwest Wapiti, Wapiti and Simonette pipeline
system near Grovedale, Alberta at 12-30-68-8 W6M.
• The processing will occur at the existing SemCAMS operated sour gas
processing facility, Kaybob South No. 3 (K3) Gas Plant located at
01-15-59-18 W5M.
• The existing SemCAMS operated Northwest Wapiti operated pipeline will
be expanded under a separate application which will accommodate the
new volumes.
• The proposed pipeline will operate at a maximum operation pressure
(MAOP) of 14,600 kPa.
Safety
• In order to minimize the risk associated with
operating the pipeline, and reduce the extent of
the EPZ, the proposed Redwillow and the NPSE
pipeline will be divided into a number of
segments by the installation of strategically
placed Emergency Shutdown Valves (ESV).
• These valves minimize the volume of sour gas
that could be released in the event of a pipeline
failure by automatically closing if there is a
sudden loss of pressure.

Emergency Planning
• The Emergency Planning Zone (EPZ) is the required area where public
protection activities are initiated in the event of an emergency.
• In order to minimize the risk associated with operating the pipeline, and
to reduce the extent of the EPZ, the pipeline will be divided into a
number of segments by the installation of strategically placed
Emergency Shutdown Valves (ESDV).
• The anticipated size of the EPZ for the pipeline depends on the
population density, with a smaller EPZ in populated areas and a larger
zone in non-populated areas. The anticipated EPZ radius will be
approximately 14 km in populated areas and 30 km in non-populated
regions.
• SemCAMS has an excellent record in protecting the health and safety of
the public, its employees and its contractors.
• All of SemCAMS’ operating units conduct regular emergency
preparedness exercises to ensure the existing plans and responses are
timely and effective.
• It is SemCAMS' desire and intention to engage and work together with
the affected stakeholders to develop an Emergency Response Plan
(ERP) for the proposed Redwillow Pipeline.

Project Schedule
Construction
Construction Steps
Pipe delivery and storage plans
Welding and Inspection
The pipe will be delivered to strategic
locations along the route and it will be
neatly stacked in designated areas as
required for construction plans.
Sections of pipe are welded together
to form one continuous pipe and bent
as needed to fit the trench contour. The
welds and pipe coating are inspected for
conformance to external standards.
Preparing the right-of-way
Clearing – all impediments to construction
including trees, boulders and brush are
cleared.
Grading – on freehold lands topsoil
will be stripped and stored separately
for replacement. Limited grading is
undertaken, as needed to facilitate
movement of construction equipment.
Permanent right-of-way – generally will
be 25 metres wide.
Temporary workspace – may be required
at specific locations to facilitate soil
storage, erosion containment, equipment
set-up and operation and pipe stringing,
especially at waterway, road, and utility
crossings.
Stringing and Trenching
The pipeline will be typically buried 1.5
metres deep. The depth of cover may vary
depending on location and the type of
surface activities above the pipeline.
Lower-in and Backfill
The welded piping string is lowered
uniformly into the trench and carefully
covered with the previously excavated
soils.
Clean up and Restoration
Right-of-way is restored to resemble as
close as possible its original condition and
revegetated with approved seed mixes.

Setbacks and Right-Of-Way
• A setback is defined as the minimum separation between oil and gas
facilities and dwellings and public facilities. When determining the
pipeline route, SemCAMS proposes to maintain an average setback of
at least 500 metres between the proposed pipeline and any permanent
dwelling.
• The width of the proposed permanent right-of-way will generally be 25
metres. Extra width may be acquired along certain sections to meet
safety and operating requirements.
• During construction, temporary workspace will be required at river,
creek, road and utility crossings, as well as, areas requiring extensive
grading. This temporary workspace is only required during construction
and will not be necessary once construction is complete.
• The amount of temporary workspace required will vary depending on the
terrain, presence of adjacent land uses and the nature of the
construction activity being carried out at a particular location. The width
of temporary workspace is typically 30 metres, but can range from 15
metres to over 40 metres at select locations.

Regulatory Information
The Redwillow Pipeline Project involves crossing a provincial boundary and
therefore approval for it will require the preparation of an application to the
National Energy Board (NEB).
SemCAMS plans to proceed with the regulatory application for the proposed
project early in the fourth quarter of 2007. This includes an application to the
NEB to satisfy Section 52 of the NEB Act.

Environmental and Socio-Economic
Assessment
An Environmental and Socio-Economic Assessment must be undertaken in
support of the National Energy Board (NEB) application, and to meet the
requirements of the Canadian Environmental Assessment Act. The NEB Filing
Manual provides specific direction as to the nature and scope of the work to be
undertaken, including the details of the biophysical, social and economic
elements to be studied, surveyed, analyzed, and which collectively provide the
information to conduct an impact assessment for the proposed project.
Studies being performed include:
• Wildlife Survey
• Fish and Habitat Assessment
• Heritage Resources Impact Assessment (HRIA)
• Wetlands Survey
• Soils Survey
• Vegetation Studies
• Traditional Land and Resource Use
• Socio-cultural Assessment
• Economic Assessment
• Cumulative Effects Assessment
