Quantum Murray LP has snagged a $33.5-million multi-year contract for the final remediation phase of British Columbia’s Rock Bay, the province’s most contaminated and expensive site on record.
With preparation set to begin in June 2014 at the Transport Canada-owned site, Quantum Murray will construct a cofferdam to prevent any water from affecting the excavation work. Approximately two million litres of water will be pumped out from the harbour so that excavations can be done in dry conditions.
The Rock Bay site was once home to a manufactured gas plant, a predecessor company to BC Hydro. The company gasified coal, then dumped the resulting tar and chemicals into Rock Bay Harbour from 1862 to 1949. The contaminated soil and sediment will be removed and sent off-site for treatment and disposal.
Remediation should start by July 2014, announced Transport Canada.
“Completing the final stage of the Rock Bay project demonstrates our government’s ongoing commitment to remediating contaminated sites and protecting the environment,” Lisa Raitt, Minister of Transport, stated in a May 16, 2014 announcement from Victoria.
Between 2004 and 2006, the majority of the Rock Bay area was jointly remediated by Transport Canada and BC Hydro (stage one and two). Over 200,000 tonnes of contaminated soil have been removed so far.
The latest contract requires Quantum Murray to complete all site work by November 15, 2015.
Following the remediation, the land will be divested to the Songhees Nation and the Esquimalt Nation from southern Vancouver Island.
The Rock Bay Remediation Project is funded through the Federal Contaminated Sites Action Plan, which is co-ordinated by Environment Canada and the Treasury Board of Canada Secretariat. The plan provides funding to assess and remediate federal contaminated sites.
