Public Health Overlooked in Fonderie Horne Contaminant Releases

The ongoing issue regarding contaminant releases from the Fonderie Horne in Rouyn-Noranda has raised significant public health concerns. Recent developments indicate that the provincial government is considering extending the deadlines for the facility to reduce its arsenic emissions.
Concerns Over Public Health
The government of Quebec, led by Premier François Legault, has not consulted the Provincial Public Health Directorate regarding these potential extensions. The Directorate confirmed that it had not been involved in discussions about prolonging the facility’s permit until 2033. Previously, health officials had been asked for their opinion on a temporary extension to March 2029, which would only ensure that emissions reach the minimum threshold of 15 nanograms per cubic meter (ng/m³).
The Institut national de santé publique du Québec (INSPQ) also reported it was not consulted about these recent changes, although it had been involved in earlier stages of this decision-making process. Aurèle Iberto-Mazzali, a spokesperson for the INSPQ, stated that the current modifications were not anticipated during their preliminary assessments.
Extended Permit for Fonderie Horne
The proposed extension would permit Fonderie Horne to maintain arsenic emissions at the current threshold for an additional four years, until 2033. Moreover, it aims to delay the enforcement of regulations for other contaminants such as cadmium, lead, sulfur dioxide (SO2), and fine particles.
The changes will be enacted through an amendment to Bill 111, which seeks to modify the Environmental Quality Act. Following the announcement of these adjustments, public health officials from the Abitibi-Témiscamingue region publicly condemned the proposed relaxations, arguing they exceed a mere timeline extension.
Political Choices and Municipal Involvement
In defending its decision to bypass public health consultations, the Legault government cited previous public health advice on earlier matters. They emphasized the political choice to provide predictability for Fonderie Horne, aiming to facilitate necessary investments in emission reduction.
Additionally, the government is relying on alleged support from the Rouyn-Noranda City Council. However, legal experts have indicated that this support lacks validity, as it was discussed in a closed session and not formally adopted during a public council meeting. This has led to dissatisfaction among certain council members, who voiced concerns over the procedural integrity of the council’s support.
Federal Funding Prospects
The situation has also garnered attention from the federal government, which is reportedly prepared to allocate $150 million to Glencore to assist with the reduction of emissions from Fonderie Horne. However, Ottawa is awaiting the approval of the proposed relaxations by Quebec before committing funds.
Federal officials highlight the importance of Fonderie Horne as Canada’s only copper foundry, viewing it as a strategic asset. Meanwhile, Quebec has declined to provide additional funding to Glencore without assurances on emission reduction compliance.
- Key Points:
- Proposed extension of arsenic emissions timeline for Fonderie Horne until 2033.
- Health authorities not consulted on new proposals.
- Federal government ready to support funding contingent on Quebec’s approvals.
- Concerns raised by local public health officials regarding safety and environmental impact.
The future of public health in Rouyn-Noranda remains uncertain as stakeholders navigate the complexities of environmental regulations and political decisions affecting Fonderie Horne.
