Quebec plan to ease limits on nickel emissions irks regional health boards, Limoilou residents

Environment Minister Benoit Charette says the CAQ government will forge ahead with a plan to relax provincial regulations on nickel emissions, despite pushback from regional health authorities, opposition parties, the Quebec City mayor and citizens' groups.

A motion tabled last December laid out the plan to increase the amount of nickel allowed in the air per day from 14 nanograms per cubic metre (ng/m³) to a maximum of 70 ng/m³ — providing the annual average is 20 ng/m³ or lower.

Charette said the move is part of the province's transition to cleaner energy and is supported by Quebec's public health institute, the INSPQ, and the latest scientific data.

"I have a very clear mandate to fight against climate change, to significantly reduce our greenhouse gas emissions," Charette told reporters at the National Assembly Thursday. "We have to electrify our transportation, and to do that we need nickel."

Since 2013, Quebec has had some of the strictest regulations on nickel emissions in the world, allowing only 14 ng/m³ of nickel in the air per day.

In the Abitibi-Témiscamingue and Nunavik regions, where nickel mines are located, emissions have surpassed that threshold on several occasions. The same holds true for the Quebec City neighbourhood of Limoilou, which is close to several emission-spewing factories and a major port.

In high concentrations, nickel is carcinogenic. But demand for the silvery white metal, most commonly used to strengthen stainless steel, has seen a resurgence, as nickel is a key ingredient in the lithium-ion batteries that power electric and hybrid vehicles.

Quebec City has asked to be exempt from the proposed higher emission rules. People who live in Limoilou have also protested against the proposed changes.

All the opposition parties in the National Assembly, Québec Solidaire, the Quebec Liberal Party and the Parti Québecois, have voiced their disapproval as well.

Quebec's 18 regional health authorities all oppose the new regulations, recently submitting a 12-page document as part of public consultations on the proposed regulatory change.

Among their arguments, they say:

In their memo, the regional health directors say given all of the uncertainty, they want Quebec to maintain the status quo. But Charette insists the province has done its due diligence.

"I don't want to question the good faith of the regional [health] authorities," he said."But the work that started years ago was done and validated by provincial public health [officials] and not the regional authorities."

A representative for the INSPQ was part of an inter-ministerial group tasked with reviewing the findings of independent experts and studying the impact increased emissions could have on people's health, the environment and the economy. The full report is available online.
