Regulatory Process 1. A fter we gather more stakeholder input and other technical and environmental information, we will further refine the preferred and alternate routes and submit our Facilities Application to the Alberta Utilities Commission (AUC). The AUC ensures the fair and responsible delivery of our utility services. The AUC will review the Facilities Application through a process in which stakeholders can participate. 2. W hen the AUC deems an application is complete, a Notice of Application is issued to parties that may be directly and adversely affected by the proposed project. This notice is also typically published in local newspapers. 3. T he AUC can approve, approve with conditions or deny a Facilities Application.
Definition
Alberta Utilities Commission The Alberta Utilities Commission (AUC) ensures the fair and responsible delivery of Alberta’s utility services. AltaLink submits applications for new transmission projects to the AUC and the AUC reviews them in a public process.
What progress have we made? Your continued input is important to our project and helps us identify the route with the lowest overall impact. During the first stage of consultation we received valuable stakeholder input about the preliminary route options. We used this stakeholder input and the results from further studies and field work, including environmental evaluations, to refine the preliminary route options to preferred and alternate routes. We want your input about the preferred and alternate routes.

Project cost The estimated cost of this project is between $95 to $145 million, which would be approximately nine to 14 cents per month on the typical residential utility bill.
Foothills Area Transmission Development (FATD) The Alberta Electric System Operator (AESO) has identified the need to strengthen the transmission system in Calgary and the communities south and east of Calgary. The AESO is an independent, not-for-profit entity responsible for the safe, reliable and economic planning and operation of Alberta’s electric system. The Langdon to Janet Transmission Project is one of the projects identified in the FATD. This project will: • ensure the transmission system will meet growing demand in developing areas and maintain a reliable supply of electricity • ensure power from new generation plants, including gas and wind power, is connected to Alberta’s electric grid
Did you know? A reliable transmission system keeps costs low by connecting diverse sources of power generation to the grid. Transmission costs make up about 10 per cent of the average residential utility bill. Generation costs – the cost of actually creating power – make up the largest portion of a bill, at more than 50 per cent. The transmission system always hooks up the lowest priced generator to the grid first, so generators compete to provide Albertans with cost-effective electricity.

The alternate route may be used in conjunction with the preferred route. The alternate route: • does not parallel any existing transmission lines • follows existing or proposed linear features for one third of its length, including storm water conveyance canals and a railway right-of-way • requires a new 60 metre right-of-way for its entire length • creates new visual impacts where there are currently no transmission lines
Variant route segment AltaLink is including for consideration a variant of the preferred route from point designation C250 east along the abandoned railway right-of-way. This segment: • could reduce fragmentation by re-aligning the transmission line into an existing right-of-way • has a higher amount of residences located nearby • is shorter in length and estimated to be a slightly lower cost route

Landowner compensation Easement acquisition • $10,000 per quarter: early access payment to perform environmental surveying and geotechnical work (for the preferred route only) • $250 to $5,000 per title: entry fee payment (as per the Surface Rights Act) • $1,500 minimum: general disturbance payment • $2,500 (titled unit) land damages payment: ($2,500 pre-construction; post-construction paid if applicable) AltaLink will pay fair market value per acre for the total area of the easement that crosses a landowner’s property, while the landowner retains ownership of the land. With the exception of the $10,000 early access payment, all other one-time payments are subject to the AUC’s approval of this project.
Annual Structure Payments (ASPs) Currently our 2011 rates for this project are: • $1,178 per structure per year on cultivated land • $471 per structure per year on uncultivated land Please note the ASP is different for a monopole structure.
Factors we take into consideration when determining ASPs include: • the loss of use of the area enclosed by the structure once operational • the inconvenience and additional costs associated with weed control • additional time required to operate equipment around transmission structures • additional seed required • overlap of pesticide/herbicide and fertilizer used when farming around the structure • effects on cultivation
Did you know? The amount of energy used to power home electronics in residences across Canada more than doubled between 1990 and 2007. The majority of Canadian homes have more than one television and more than a quarter of households used at least three sets in 2007. TVs, DVD players and other electronic devices are drawing more and more power from the grid on a continual basis.
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? • electric utility equipment and facilities • household electrical appliances • building wiring
C ommon questions about electrical effects include: Q Will there be TV/radio interference? A There is no impact on cable TV. Other impacts can typically be mitigated. Q A
Will there be wireless internet interference? There is typically no impact.
Q A
Will Global Positioning Systems be affected? There is typically no impact.
Q Will there be any affect to cardiac pacemakers? A Most have shielding, but we can provide answers to you about the specific model. Q A
What about audible noise? AltaLink adheres to the AUC noise guidelines.
Q What about building and fence induction? A This is mitigated through grounding we install during construction. Q What about stray voltage? A This is not caused by transmission lines; it is more typically caused by distribution lines or local wiring.
Environmental Evaluation An Environmental Evaluation identifies environmental features within the project area through existing data and field surveys. Additional information is gathered from consultation with provincial and federal regulators, landowners and the public. This information is used to assist in route development. Potential effects from the project are identified, so that mitigations can be developed to minimize or eliminate these effects. Information within the Environmental Evaluation typically includes: • wildlife and vegetation inventories • wetlands, watercourse and groundwater • threatened and endangered species identification • terrain and soil inventories
