Massey transmission needs federal review

BC Hydro’s rendering of two future transmission towers, 75 and 120 metres tall, carrying high-voltage power lines over Deas Island Regional Park and then over the Fraser to another 120-metre tower (not shown) in Richmond. The view looks northeast toward a rendered Massey bridge.

“I am deeply concerned about the overhead transmission lines. What are the health risks? How would it affect the viewscape?” Those comments from Carol Day, a Richmond councillor, stemmed from a Richmond News article, “BC Hydro reveal plans to reroute power lines from a decommissioned Massey Tunnel.”

The context: In Hydro’s illustration, the two transmission towers fading behind a tree would be on the west side of Deas Island Regional Park, near the south and north shores. Transmission lines would hang between them.

From Deas Island in Delta, the lines would be suspended over the Fraser River to a third tower on the Richmond side. It is not depicted, perhaps so it won’t be noticed until it rises higher than a 37-storey building.

My response to the concerns: There was a long struggle in Tsawwassen about electromagnetic fields (EMFs) from high-voltage overhead lines, with possible links to problems like leukemia. If towers start dangling high-voltage lines over the park, there won’t be much left of viewscapes and viewers.

As a recent Metro Vancouver report puts it, “The proposed bridge and the associated BC Hydro transmission relocation project will . . . create permanent noise, debris and visual impacts.”

Sensibly, the City of Richmond has insisted that the towers are the worst option for a transmission route. Despite “consultation” with Richmond, Metro and a few citizens, Hydro has stuck to the decision it started with.

An engineer who took part in the consultation as a Delta resident tells me it’s safe and easy enough to lay transmission cable “within a box girder on, under or above the bridge deck.” For Hydro, though, it’s cheaper to quickly build separately—with no careful cooperating—before people catch on.

To Hydro: To save a thousand times as much, stop Site C. Or, to help enable a transmission cable under the riverbed, get Port Metro Vancouver to not dredge the ship channel two (or more) metres deeper.

The urgent need is for a federal environmental assessment, preferably by review panel, to address the overall impact of the Massey project, including Hydro and Port Metro aspects. It would have teeth, unlike the feeble B.C. assessment that ignores such aspects.

Our best chance is to support the powers who care. That would involve Metro Vancouver and at least one Member of Parliament with influence in Ottawa and a belief in action for the nature of the Fraser.
