INEOS Styrolution will begin the final phase of decommissioning the process units and pipelines at its Sarnia site on Monday June 2, 2025.
While work is conducted, residents in the area may notice elevated flaring as part of the safety process.
In a notice issued by Sarnia-Lambton Alerts, INEOS said the elevated flaring is expected to continue until Thursday, June 19.
The styrene monomer production site on Tashmoo Avenue has been shut down since April 2024, after orders were placed on the facility in response to members of Aamjiwnaang First Nation feeling ill due to elevated levels of benzene emissions.
In June 2024, INEOS announced plans to permanently close the site.
Benzene destocking at the Sarnia facility wrapped up in the fall.
