Algoma Steel Inc. - Environmental Compliance Approval (air)

This proposal is for an Environmental Compliance Approval (air & noise) amendment for all emissions from Algoma Steel Inc. (Algoma), an integrated iron and steel manufacturing facility located in Sault Ste. Marie, Ontario.

Current operations at the Sault Ste. Marie facility include:

• receiving, handling and storage of raw materials (coal, iron ore, limestone, scrap metal),
• coke production from coal,
• iron production in blast furnaces,
• steel making in furnaces,
• finishing (heat treating, pickling, annealing and tempering), and
• shipping

Algoma is applying to transition its manufacturing process from integrated basic oxygen steelmaking to electric arc furnace (EAF) steelmaking. The transition to EAF steelmaking is scheduled to occur over the course of up to five years, with full independent operation of the EAF process by 2029. The application includes all sources at the facility, including sources during the transition to EAF steelmaking.

New equipment includes:

• two electric arc furnaces,
• one cooling tower, and
• two fume treatment plants, including baghouse dust collectors.

Emissions to the air from this facility includes:

• benzene,
• benzo(a)pyrene,
• total suspended particulate,
• sulphur dioxide,
• nitrogen oxides,
• carbon monoxide,
• manganese,
• nickel,
• aluminum,
• ferric oxide,
• metallic iron,
• magnesium,
• calcium carbonate,
• ethylene,
• fluorene,
• pyrene,
• hydrogen sulphide, and
• total reduced sulphur.

Algoma has also applied for site specific standards for benzene, benzo(a)pyrene, total suspended particulate and sulphur dioxide emissions from the facility. The site specific standards application is currently under review by the Ministry and a separate environmental proposal will be posted for public comment.
