Stelco seeks permission to fill Nanticoke quarry with steelmaking waste

Stelco Lake Erie Works is two years into preparing an environmental assessment that, if approved, could see its quarry site filled with additional waste from both its site and Hamilton’s Steel Works.

The 5.5 hectare, 34-metre-deep former limestone quarry is on the west side of the Nanticoke site, and since 1984 has been used to dispose nonhazardous secondary materials from the steelmaking process. The original permit allowed the company to dispose of 1.3 million cubic metres of blast furnace slag, steelmaking slag, and other nonhazardous wastes.

Now, Stelco wants to add an additional 1.185 million to 1.685 million cubic metres of secondary steelmaking materials — including dust, sludge and blast furnace slag — over the next 15 to 25 years, which would include 25 per cent of waste produced at the Hamilton site over that time.
