Keeping Our Right-of-Ways Clear

Energy Supply, Environment, Reliability

Jun 28, 2013  8

 Yukon Energy has more than 1,000 kilometres of transmission lines, and we must keep the right-of-ways under the lines clear to ensure reliability of our system. Currently we mow the right-of-ways and manually remove the trees under our powerlines. However vegetation experts have reviewed our practice and suggest that using herbicides in addition to our current practices will provide benefits both from an economic and an environmental standpoint.

Using herbicides would mean that the right-of-ways would be disturbed less often by heavy equipment, because we wouldn’t have to manually remove vegetation so often. It could promote the growth of grasses and other vegetation desirable to animals and humans, since herbicides can be selectively applied to target certain plants or trees. It also reduces bird nest disturbances.

This summer, we will be testing some herbicides in the Whitehorse area to see if it makes sense for us to add their use to our vegetation management program.

The small plots, near the Long Lake Road and in the vicinity of the Takhini Hot Springs Road, will be clearly marked with signs before the work begins. See the maps below for their exact locations.

Herbicides are commonly used by utilities elsewhere in Canada and abroad. The ones we are testing have been recommended by environmental experts and have been approved as safe to use by Health Canada.

We will begin our test program on July 8th and run for two weeks. During this time, we ask that you not walk through the plots, and that you prevent your pets from walking through them. While it isn’t a hazard for you to walk in the area, it could affect the results of our testing.

Please contact us if you have any questions.

Grammar bone to pick. “Rights of way”, not “right of ways”.

What are the names of the herbicides to be tested?


by Yukon Energy

The herbicides to be tested are Garlon XRT #28945, Roundup Transorb Liquid Herbicide #28198, and Arsenal.

As for the debate about “rights of way” versus “right of ways”, the Merriam-Webster dictionary says both are acceptable.

Janet, i am very concerned about this! Who is aware of this, where did you get the permits? etc.


by Yukon Energy

Yukon Energy received permits from Environment Yukon, under the Environment Act, to carry out these tests.

I am concerned about the use of herbicides.  Can you not just use boiling water?


by jozien

No no no, you cannot tell me anything but killing with chemicals is more dangerous for the environment ( us incl.) then mowing the powerline right-of-way every 5 years Just one website that tells us how dangerous roundup is. Please do not carry out your dangerous experiment!!!!

If you received permits, did you not need an environmental assessment under the YESSA?
The optics on using herbicides are terrible. This move by YEC was ill-considered; surely there are alternatives that are both easier on the environment and better for YEC’s tarnished image.
