3. IRON PRODUCTION

5. FINISHING

2. COKE PRODUCTION

Raw materials (coal,iron ore, recycledsteel) arrive by ship,truck and train toDofasco’s facility.

Rail cars take molten ironto steel making furnaces.Dofasco has 2 furnaces –the KOBM Furnace andthe Electric Arc Furnace.

Dofasco has 3 BlastFurnaces thatconvert iron oreand coke into iron.

Dofasco has 3coke plants onsite that convertcoal into coke.

Site Specific Standards are designed to improveenvironmental performance over time. Regulation419/05, under the Environmental Protection Act,phases in updated air quality standards developedby the MOECC.

MOECC has three compliance options:

MOECC’s goal of the Site Specific Standard processis “continuous improvement of emissions as newtechnologies become available”.

What is anMOECC SiteSpecific Standard?

Demonstrate emission levelswithin prescribed limits

Request Site Specific Standards(SSS) focused on the reduction of

emissions over time

Register under a TechnicalStandard

ArcelorMittal Dofasco currently meets MOECC-approved emission limits for the followingcompounds:

Total Suspended Particulate (TSP)Total Reduced Sulphur (TRS)Benzo(a)pyrene (BaP)Benzene

What’s Next (2015-2020)

ArcelorMittal Dofasco is applying for Site SpecificStandards for the compounds listed above aswell as Manganese (Mn).

New MOECC Standards for Benzo(a)pyrene,Benzene and Mn will be coming into effect in2016.
