Domtar updates E2 regulation requirements for Canadian mills

September 2, 2020  By P&PC Staff

Domtar has updated the communities where it operates pulp mills on the company’s use of hazardous substances in accordance with federal regulations.

The Federal Environmental Emergency (E2) Regulation was revised in 2019 to require companies that are using or storing a hazardous substance from a list of 260 to proactively inform the public about risks and emergency procedures in the case of a leak.

As a result, Domtar has publicly disclosed that it uses chlorine dioxide in its kraft pulp manufacturing processes at its Kamloops mill in B.C., its Windsor mill in Quebec, and at its Espanola and Dryden mills in Ontario. The company also uses hydrochloric acid at the Dryden mill.


In a company statement, Domtar stresses that these products has been safely manufactured, used and stored onsite at each mill for years, and that they are constantly improving their prevention measures.

The company also continuously monitors air quality to ensure there is no release of gas into the air, and has installed spill-containment measures at all mills that would control offsite impact should a leak happen.
