Emissions from Birla Carbon, a manufacturing company, were identified as a significant source of the black soot that descended on various neighborhoods in Hamilton last month, as confirmed by Ontario’s Ministry of the Environment, Conservation and Parks (MECP).
The issue of black dust settling over Hamilton neighborhoods has been a longstanding concern for decades, particularly in proximity to the eastern industrial zone. However, residents and local leaders noted that the soot fallout in early July was unusually heavy and affected regions not typically impacted.
The severe sooty fallout, which coated homes and even affected pets and children, prompted numerous residents to urge elected officials to address the situation. In response, ministry spokesperson Lindsay Davidson informed CBC Hamilton that Birla has been referred for a formal investigation by the ministry’s environmental investigations and enforcement branch for potential violations of Ontario’s environmental regulations.
Birla Carbon affirmed its full cooperation with the ministry’s inquiries, although spokesperson Roysten Dmello refrained from addressing specific questions regarding the cause and nature of the emissions. The company, known for producing carbon black, operates its sole Canadian facility on Parkdale Avenue N. and has a presence in 14 countries.
Hamilton Public Health received the government’s analysis and sampling results, with the ministry emphasizing that Birla Carbon will be required to take all necessary measures to prevent similar incidents in the future. Public health officials are currently reviewing the findings and consulting with experts to assess any potential health risks associated with the soot exposure.
Councillor Tom Jackson expressed concern over receiving a high volume of complaints from Ward 6 residents about the soot, many of whom suspected Birla Carbon as the source. He urged the company’s leadership to engage with residents and advocated for imposing a substantial fine on the company, with plans to allocate the funds towards reimbursing residents for cleanup expenses.
While the exact composition of the emissions in July remains undisclosed, a proposed government standard from 2023 highlights the significant sulphur dioxide emissions from Ontario’s carbon black facilities, particularly in Sarnia and Hamilton, which can have adverse respiratory and cardiovascular effects on individuals.
The ministry’s disclosure coincided with CBC Hamilton’s coverage of a McMaster University study that identified toxic chemicals consistent with coal combustion in the soot sampled from homes in Hamilton. The researchers highlighted elevated levels of dust and polycyclic aromatic hydrocarbons (PAHs) near the industrial area in northeast Hamilton, indicating a potential link to coal combustion sources. Further investigation is needed to pinpoint the exact industrial sources of these chemicals.
