Over-budget construction bids are causing delays for the $138.9-million remediation of Canada’s largest coal tar contamination site in Hamilton, Ontario, known as Randle Reef.
Environment Canada confirmed the budget overrun, but still expressed support for the cleanup, which had been set to begin in spring 2014. The start of the cleanup may now be pushed into 2015.
Project officials will meet in July 2014 to discuss the details of the construction bids.
The project involves the construction of a capped engineered containment facility (ECF) of about 7.5 hectares, consisting of a peninsula attached to Hamilton Port Authority’s Pier 15. The ECF would cover in-situ remediation of about 130,000 m3 of contaminated sediments and contain about 500,000 m3 of dredged contaminated sediments from the surrounding areas.
US Steel is contributing 10,000 tonnes of hot rolled steel sheet and another 700 tonnes of steel products to build the ECF.
