Why northern Ontario radioactive waste ended up in Corunna — starting in July
Ontario’s Ministry of Transportation recently revealed that some radioactive waste from an old mill near Lake Nipissing has made its way to the Sarnia area. The material, which had been sitting at the mill for 70 years, was originally intended to be shipped near Sudbury, sparking a year-long public outcry from residents of Nairn and Hyman, a small township of about 400 people.
The tailings contain low-level radiation due to small amounts of uranium present in the ore. In response to public concerns, the province shifted its plans for the disposal of the waste. The material was transported to Clean Harbors in Corunna, located in St. Clair Township within Lambton County.
Julia Casin, from the transportation ministry, stated, “A stockpile of niobium rock tailings was transported to a private licensed disposal facility run by Clean Harbors near Sarnia in July, in accordance with all regulatory requirements.” Despite attempts to reach out to Clean Harbors for comment, CBC News did not receive a response by publication.
Casin emphasized that the ministry adheres to strict safety and environmental standards when transporting mining materials, including niobium rock tailings. These tailings are not classified as hazardous substances, and their transportation is considered a low-risk operation by the province.
Nipissing First Nation Chief Cathy Stevens informed CBC News that efforts to remove the tailings are expected to be completed by the end of the year. The 18,600 cubic meters of tailings originated from the Nova Beaucage Mine near Lake Nipissing and had been stored at a mill in the community, near a residential area, for seven decades.
The province’s decision to relocate the radioactive waste to a licensed disposal facility reflects its commitment to ensuring the safety of the environment and surrounding communities. With ongoing efforts to address the issue, stakeholders are hopeful for a resolution that prioritizes public health and environmental protection.
