Public consultation
Your involvement is important to us.
AltaLink understands that landowners, occupants
and residents have information we need to
consider when evaluating potential routes.
Input from affected stakeholders is very
important to the process of selecting the
route with the lowest overall impact.
We will work with you to ensure your questions
and concerns are understood and responded to.
After this preliminary stage of consultation we
will use your input to refine route options and
will consult with you again about these refined
options in the winter of 2010.
One-on-one consultation
To set up a one-one-one consultation please talk
to an AltaLink representative or call us toll-free
at 1-877-269-5903.
Our information centre also provides the
opportunity to meet with AltaLink representatives
at times convenient for you. The information
centre is scheduled to be open from 12 - 8 p.m.
and is located at 60-1825 Bomford Crescent SW.
The information centre will be open the
following dates:
Thursday, August 19

Key players
AltaLink
AltaLink is an independent company that owns
and operates approximately 11,800 kilometres
of transmission lines and 270 substations.
We provide electric service to more than
85 per cent of Albertans and own the majority
of the transmission system in central and
southern Alberta.
The Alberta Electric System Operator (AESO)
The AESO is an independent, not-for-profit
entity responsible for the safe, reliable and
economic planning and operation of the
Alberta Interconnected Electric System.
The AESO determines the need for transmission
reinforcement and directs Transmission Facility
Owners, such as AltaLink, to submit a Facility
Application for permitting and licensing to construct
and operate transmission facilities.
The Alberta Utilities Commission (AUC)
The AUC is a quasi-judicial agency that ensures
the fair and responsible delivery of our utility
services. The AUC is the provincial regulator
responsible for reviewing Facility Applications.
AUC approval is required before construction
of facilities can occur.

Potential Areas For Transmission Development
Alberta’s electrical grid needs more capacity
to make room for power generated from new
wind farm projects proposed throughout
southern Alberta. New transmission lines are
required to support this growth and collectively
these projects make up the Southern Alberta
Transmission Reinforcement Project (SATR).
The Medicine Hat 138 kV Project is included
in the SATR. The AESO filed the need for SATR
in a formal application with the AUC in
December 2008. The AUC completed a public
hearing in June 2009 in Lethbridge to review
the need for these projects. The AUC approved
the need for these projects in September 2009.

The Medicine Hat 138 kV Transmission
Project includes:
• A new 138 kV double circuit transmission line
from the existing Bullshead Substation to the
proposed Bowmanton Substation
• Upgrades to the existing single circuit 138 kV
transmission line between the existing
Medicine Hat Substation and the existing
Chappice Lake Substation area by removing
the existing line and constructing a new
double circuit 138 kV line
• Some structures may be removed, and some
new structures added in the immediate area
around both the Bullshead Substation and
Medicine Hat Substation
• A new 138 kV single circuit transmission line
approximately 800 metres in length connecting
the proposed Bowmantion Substation to the
existing Chappice Lake Substation
• Additions to the proposed Bowmanton
Substation and existing Medicine Hat, Bullshead
and Chappice Lake Substations to accommodate
the proposed new transmission lines
Landowner compensation
AltaLink is committed to providing fair and
reasonable compensation to landowners who
may have transmission facilities on their property.
We provide compensation for easements and
Annual Structure Payments (ASP) for the land
used by our transmission facilities.
Information regarding compensation and the
easement acquisition process will be available
throughout the consultation process.
Environmental evaluation
The environmental evaluation involves reviewing
available databases, maps and other references
along with field surveys. It examines:
• Provincial fisheries, wildlife and vegetation
inventories
• Alberta natural heritage and cultural
area inventories
• Wetlands and water body data
• Environmental literature
• Aerial and roadside reconnaissance
of potential routes
• Public input and regulatory consultation
• Rare plant and vegetation surveys
• Wetland and watercourse surveys
• Wildlife surveys
• Soil and geo-technical assessments
The environmental evaluation will help define
mitigation measures to prevent or reduce
potential environmental impacts. Environment
How does AltaLink consider the environment
in project planning?
• Incorporate environmental evaluation results
into route selection process
• Avoid environmentally sensitive areas
• Where avoidance is not possible, develop
mitigation plans to minimize disturbance
• Parallel existing corridors such as roads,
pipelines, power lines and quarter lines
where applicable
• Ensure routes meet all current
environmental regulations
Route identification process
This diagram shows how we identify potential
route options.
Route identification criteria
The table below lists the general criteria we take
into consideration when identifying and refining
potential routes.
Criteria
Examples
Agricultural
• loss of crops
• r educed efficiency
of field operations
Residential
• loss of developable
lands and constraints
on development
• proximity to residences
Environmental
• alteration of natural
areas and interference
with outdoor educational
opportunities
Cost
• c onstruction costs and
land acquisition costs
Electrical
• reliability and reparability
of the line
Visual
• visual impact of structures
and lines as seen from
residences, farms, roads and
recreational installations
Special
considerations
• electrical interference
with radio transmitting
stations and other
telecommunication
equipment etc.
Please let us know if you think there are other
important criteria we should consider when
refining route options.
Project details
This project involves transmission line
development in the Medicine Hat area.

The proposed transmission structures will be
spaced approximately 140 metres apart (460 feet).
Some route segments follow open and unopen
road allowances. In these circumstances
structures will typically be placed one metre
within the area boundary. Where not on a road
allowance a right-of-way 20 metres in width
(65 feet) will be required.

Substations
• Improvements to the existing Medicine Hat,
Bullshead and Chappice Lake substations
will occur on property within the substation
fenced area.
• Electrical equipment, and two transformers,
will be added within the fenced boundaries
of the proposed Bowmanton Substation.
These transformers will adjust voltage levels
from 240 kV to 138 kV and allow movement
of power along the wires. The proposed
Bowmanton Substation is part of the Cassils
to Bowmanton project.

Electric and magnetic fields (EMF)
AltaLink’s position on EMF
AltaLink recognizes that some people are
concerned about EMF and we treat those
concerns very seriously.
Based on more than 30 years of research,
national and international health agencies have
not concluded that EMF associated with high
voltage transmission lines will adversely affect
your health or the health of plants and animals.
They have not recommended the general public
take steps to limit their everyday exposure to
EMF. AltaLink will ensure any problems caused by
interference from our facilities are corrected and
all applicable guidelines are met.
Where can you find EMF?
• Earth’s magnetic field
• electric facilities
• appliances
• building wiring
Common questions around electrical effects include:
Will there be TV/radio interference?
There is no impact on cable TV. Other impacts
can typically be mitigated.
Will Global Positioning Systems be affected?
There is typically no impact.
Will there be wireless internet interference?
There is typically no impact.
Will there be any affect to cardiac pacemakers?
Most have shielding, but we can provide answers
to you about the specific pacemaker model.
What about audible noise?
AltaLink meets AUC noise guidelines.
Building and fence induction?
This is mitigated through grounding we install
during construction.
What about stray voltage?
This is not caused by transmission lines; it is more
typically caused by distribution lines or local wiring.
