Transmission Line 754L Relocation

AltaLink Management Ltd. and TransAlta Corporation
Rebuild approximately 20 metres of Transmission Line 742L in a T-tap configuration
from the relocated segment of Transmission Line 754L to the Exshaw 985S Substation.
(collectively referred to as the proposed project)
5.
AltaLink also applied on behalf of TransAlta to update Licence U2002-923 in order to
reflect the relocation of Transmission Line 754L. AltaLink stated that no changes were being
proposed for TransAlta’s facilities and TransAlta expressed no concerns regarding the proposed
project.
6.
The applications were registered as Application 21552-A001 and Application 21552-A002
on April 26, 2016, and were considered as Proceeding 21552.
7.
The Commission issued information requests on May 16, 2016 and July 12, 2016, and
AltaLink responded to the information requests on May 24, 2016 and July 19, 2016, respectively.
8.
The Commission issued a notice of applications on May 16, 2016. The deadline for filing
submissions with the AUC was June 6, 2016. The notice was sent directly to landowners,
companies and agencies within 800 metres of the proposed project.
9.
The Commission received return mail from the notice, which was forwarded to AltaLink
with a request to obtain updated address information. On June 17, 2016, AltaLink provided
updated addresses and stated that stakeholders with the updated addresses were mailed or
emailed a project-specific information package and the AUC’s notice of applications. AltaLink
also stated it was unable to locate new mailing addresses for eight stakeholders and, as such,
hand-delivered a project-specific information package and the AUC’s notice of applications to
the legal land locations these stakeholders either own or occupy.5

No submissions were received for this proceeding.
Discussion
11.
AltaLink filed the applications at the request of Lafarge Canada Inc. (Lafarge), a
customer of AltaLink. Lafarge asked for the relocation in order to accommodate the future
expansion of Lafarge’s quarry, which is located on Crown land.
12.
The proposed project would be located on a combination of land owned by the
Municipal District of Bighorn and Crown land in the Green Zone of Alberta. The area is a
combination of montane terrain and vegetation types, and residential development, including the
hamlet of Exshaw and the Lafarge cement plant and quarry. The proposed project area is from
LSD 12 of Section 23, Township 24, Range 9, west of the Fifth Meridian to LSD 11 of
Section 28, Township 24, Range 9, west of the Fifth Meridian.6
13.
The proposed rebuild and relocation of Transmission Line 754L would consist of a
combination of one-pole, two-pole and three-pole structure types and vertical dead-end structure

types. Transmission Line 754L would be relocated approximately 1.3 kilometres south of its
existing location, to just north of the Bow River.
14.
In its route determination process for Transmission Line 754L, AltaLink set up a study
area with a north boundary located along the closest north quarter line of the existing
Transmission Line 754L, a west boundary approximately 200 metres west of Lafarge’s quarry
lease, a south boundary along the Bow River and an east boundary located along the east
quarter line of the northwest quarter of Section 23, Township 24, Range 9, west of the
Fifth Meridian.
15.
AltaLink’s proposed route for Transmission Line 754L would parallel Highway 1A for
approximately 1.5 kilometres. The proposed route of Transmission Line 754L would also
parallel an ATCO Gas pipeline and a Canadian Pacific Railway rail line. AltaLink stated the
proposed route of Transmission Line 754L would not traverse pasture or harvested land, would
not be located on native prairie, in parks or protected areas, and would not impact wetland
habitat.
16.
AltaLink determined that a route option for Transmission Line 754L could not be located
further north of the existing location because it would still remain inside Lafarge’s quarry lease
boundaries. A route option further south of the proposed route would be located in a provincial
park, with the closest existing disturbance being the TransCanada Highway. Thus, routing
options further north or south would have resulted in a longer line length and additional
disturbance and associated land impacts. AltaLink stated that the route proposed for
Transmission Line 754L represents a low impact location.
17.
As a result of the relocation of Transmission Line 754L, the connection point with
Transmission Line 742L was proposed to be relocated. Consequently, approximately 325 metres
of Transmission line 742L was proposed to be salvaged and a portion was proposed to be rebuilt.
The proposed rebuild of Transmission Line 742L would consist of the replacement of one
single-pole span from the Exshaw 985S Substation to the new location of Transmission
Line 754L.
18.
AltaLink conducted a participant involvement program in accordance with Appendix A
of Rule 007: Applications for Power Plants, Substations, Transmission Lines, Industrial System
Designations and Hydro Developments and included occupants, residents and landowners,
leaseholders, local, regional and provincial government agencies and industry. AltaLink stated
that it ensured stakeholders were properly and adequately notified about the proposed project and
its potential adverse effects, given opportunity to ask questions and raise issues and concerns
about the proposed project, and able to provide input regarding the proposed project. Two
information sessions were held by AltaLink at the Exshaw Community Hall and two rounds of
consultation were conducted with stakeholders identified as having interests in land directly
adjacent to the proposed project. The rounds of consultation occurred between November 2014
to January 2015 and November 2015 to January 2016. AltaLink also completed a First Nations
consultation program that received confirmation from the Government of Alberta’s Aboriginal
Consultation Office as being adequate.
19.
AltaLink stated it was not aware of any outstanding concerns related to the proposed
project.

Personnel from Alberta Environment and Parks (AEP) were contacted and provided with
project information, and follow up consultation was completed to discuss project specifics. There
were no outstanding concerns from AEP. AltaLink anticipated that the potential environmental
effects from construction of the proposed project would be minimal.
21.
AltaLink stated that construction of the proposed project would occur during dry or
frozen ground conditions. Since a large portion of the proposed project would be located in an
area with little vegetation, impacts to vegetation would be minimal.
22.
Wildlife and wildlife features identified in the Environmental Field Report include an
artificial osprey platform, a herd of bighorn sheep and potential presence of both tundra and
trumpeter swans. The proposed project does not fall within the setbacks of a provincially
identified trumpeter swan area. With regard to an osprey platform located adjacent to
Highway 1A, AltaLink consulted with an AEP biologist and FortisAlberta Inc., as the osprey
platform was currently maintained by FortisAlberta Inc. AltaLink determined that the platform
would be removed to facilitate construction and re-established after construction completion.
AltaLink stated that construction was scheduled to occur outside of the osprey nesting season.
23.
AltaLink’s environmental specifications and requirements document stated that
construction activities would be carried out to meet the requirements of environmental
legislation, standards and guidelines. During construction, the environmental lead from AltaLink
would monitor project activities to identify and rectify potential environmental issues.
24.
Alberta Culture and Tourism determined that the potential for the proposed project to
affect archaeological sites was high and required AltaLink to complete a pre-construction
historical resources impact assessment. On March 2, 2016, AltaLink received
Historical Resources Act approval for the proposed project.
25.
AltaLink estimated the cost of the proposed project to be $3.3 million (within
+20 per cent / -10 per cent accuracy), paid for by the customer, Lafarge. AltaLink would be
responsible for the cost of relocating a portion of Transmission Line 754L between nodes A20
and A35, which was estimated to be $80,000 (within +/- 30 per cent accuracy). AltaLink stated
this cost would be paid through its Capital Replacement and Upgrades budget and was not
included in the proposed project budget.

Findings
26.
The Commission finds that the application complies with the information requirements
prescribed in sections 14, 15 and 21 of the Hydro and Electric Energy Act, and Rule 007.
27.
The Commission observes that AltaLink’s participant involvement program was
conducted through notification and personal consultation, and that there were no outstanding
concerns. The Commission finds that the participant involvement program undertaken by
AltaLink met the requirements of Rule 007.
28.
The Commission finds that the technical and environmental aspects of the proposed
project fulfill the requirements of Rule 007.

Transmission Line 754L Relocation
AltaLink Management Ltd. and TransAlta Corporation
29.
The Commission finds, based on AltaLink’s evidence, that the proposed project will
result in minimal environmental effects through the implementation of AltaLink’s environment
standards of practice, environment specifications and requirements document, and construction
schedule.
30.
The Commission finds that the route option for Transmission Line 754L represents a low
impact location for the proposed project, as other routing options would result in a longer line
length, additional disturbances and associated land impact. The Commission also finds that the
rebuild for Transmission Line 742L is necessary in order to connect the Exshaw 985S Substation
to the relocated Transmission Line 754L.
31.
The Commission recognizes that the proposed project was applied for at the request of
Lafarge, who asked for the relocation in order to accommodate the future expansion of its
quarry. The Commission acknowledges that the proposed project costs would be paid by Lafarge
and the cost of relocating a portion of Transmission Line 754L between nodes A20 and A35
would be paid by AltaLink through its Capital Replacement and Upgrades budget.
32.
Based on the foregoing, the Commission considers the application to be in the public
interest in accordance with Section 17 of the Alberta Utilities Commission Act.
