Local health professionals are urging the incoming Quebec administration to keep the 2029 deadline that requires the Horne Smelter in Rouyn-Noranda to meet an arsenic emissions limit of 15 nanograms per cubic metre. Their appeal follows a recent extension granted by the outgoing government, which allowed the plant additional time to bring its emissions down to the specified threshold.
The experts stress that any further postponement could compromise public health objectives tied to air quality in the region. The 15 ng/m³ target was set to reduce exposure to arsenic, a known contaminant with adverse health effects when inhaled over prolonged periods. By maintaining the 2029 deadline, officials would ensure that the smelter completes the necessary reductions within a predictable timeframe.
The previous administration’s decision to defer the deadline was intended to give the smelter a realistic window to achieve the required emission levels. Health specialists note that while the deferral provided short‑term relief for the facility, it also introduced the risk of a longer adjustment period. They argue that the current schedule remains feasible and that extending it further would delay the anticipated health benefits for the surrounding community.
Officials from the Quebec government, both outgoing and incoming, have been involved in setting and reviewing the emissions timeline. The health community’s request is directed at the new government, emphasizing that adherence to the 2029 schedule aligns with broader environmental and public health policies.
The call for the deadline to remain unchanged reflects broader concerns about industrial emissions and their impact on regional air quality. As the transition between governments proceeds, the health experts’ position adds a clear perspective on the importance of meeting established environmental standards without additional delays.
