Throughout our discussions with stakeholders, various concerns and questions were brought forward. This section addresses the feedback we commonly heard.
What to expect during construction
Construction is planned to begin in late summer / early fall 2019, and the facilities are to be completed and in operation by May 2020. We anticipate our hours of work to be Monday to Friday from 7:30 a.m. to 5:00 p.m.; however, occasional evening or weekend work may be required. We will provide more detailed information regarding potential construction impacts prior to any work starting.
During construction, you can expect typical activity such as vehicles, equipment and crews in the area. We understand that construction impacts can be challenging; however, they are generally short-term in nature and our construction staff will work as quickly and safely as possible to minimize any potential inconvenience.
Temporary lane closures
We anticipate needing to temporarily close a lane of traffic on the side of the road where crews will be working. Our goal is to maintain access to businesses during construction. We will attempt to provide advance notice of any work in the area.
During construction of the transmission line, temporary power outages may be required to allow us to complete work safely. The timing and extent of outages will be determined as we complete detailed engineering. We understand this is an inconvenience to our customers, and will work with affected customers to minimize the impact of the outages and ensure customers are notified in advance.
In some areas, we may need to trim or remove trees or other vegetation near transmission poles, wires or guy lines. This is to ensure that we meet minimum safety clearance requirements per the Alberta Electrical Utility Code.
We are taking several steps in routing and siting the line to reduce the potential visual impacts associated with the project. Where possible, we propose to:
- Follow existing linear disturbances (roads, transmission/distribution lines).
- Overbuild on existing wood pole distribution lines rather than add a separate line.
- Build taller structures or place poles to reduce obstruction of commercial signage.
Work will create typical noise associated with construction. We will take measures to ensure we comply with the City of Edmonton's Community Standards Bylaw for Noise Control. If it's necessary to temporarily exceed acceptable noise levels, we will work with the City of Edmonton to obtain the required permits.
Concerns about potential communications interference
Some stakeholders asked about the potential impact of the project on wireless signals such as radio and television transmitters, wireless internet and cellular phone networks. We do not anticipate any interference with most types of signals resulting from the transmission line, as they are typically broadcast at much higher frequencies, whereas transmission lines are classified as extremely low-frequency (the same as household appliances and wiring). There is the potential for interference with AM radio and analog television signals; however, any potential interference diminishes significantly with distance from the line.
