Emissions from Birla Carbon, a manufacturing company, were identified as the main contributor to the black soot that descended on neighborhoods in Hamilton last month, according to Ontario’s Ministry of the Environment, Conservation and Parks (MECP).
The issue of black dust settling over Hamilton neighborhoods has been ongoing for years, especially in the vicinity of the eastern industrial area. However, residents and local officials noted that the soot fall in early July was unusually heavy and affected areas not typically impacted.
The soot contamination was severe, coating residences and affecting pets and children, prompting numerous residents to call on elected representatives for action.
The ministry stated that Birla has been referred for a formal investigation by the ministry’s environmental investigations and enforcement branch for potential breaches of Ontario’s environmental regulations.
Birla Carbon stated that it is fully cooperating with the ministry’s inquiries. The company’s spokesperson did not address inquiries regarding the cause of the emissions but mentioned that they had not received any official communication from MECP about the findings.
The company’s sole factory in Canada, located on Parkdale Avenue N., produces carbon black, a fine black powder utilized in various manufacturing processes such as rubber and plastic production.
MECP has shared its findings and sampling outcomes with Hamilton Public Health. The ministry intends to compel Birla Carbon to take all necessary measures to prevent similar incidents in the future.
Hamilton’s associate medical officer of health, Dr. Bart Harvey, stated that public health officials are evaluating the ministry’s findings and consulting with toxicology experts to assess any potential health risks associated with the situation.
Although the specifics of the July emissions linked to Birla Carbon have not been disclosed, a proposed government standard for the carbon black sector pointed out that facilities in Ontario are significant sources of sulphur dioxide emissions, which can have adverse effects on respiratory and cardiovascular health.
Councillor Tom Jackson received numerous complaints from Ward 6 residents about the soot, with many suspecting Birla Carbon as the source. He urged company leaders to engage with residents and proposed imposing a substantial fine on the company, with the funds potentially being redirected to affected residents for cleaning expenses.
Hamilton has a long history of industrial jobs, but Jackson emphasized the need for businesses to take greater responsibility to prevent such incidents in the future.
A recent study by McMaster University researchers revealed toxic substances consistent with coal combustion in the sampled soot in Hamilton. The researchers found higher levels of dust and polycyclic aromatic hydrocarbons (PAHs) near the northeastern industrial area, suggesting a possible industrial contribution to the fallout.
