Tender Issued for Protective Cap
July 20, 2010 - The Sydney Tar Ponds Agency has released a tender for the construction of a protective cap over treated tar ponds sediment.It's the third step in a series of projects leading to the future development of the remediated site.Construction of the multi-layer protective cap will begin in the fall, and is scheduled for completion in summer, 2013. It will include a grading/bedding layer, a geosynthetic clay layer, a geocomposit drainage layer, protective fill, topsoil and hydro seed. The cap is designed to direct rain and groundwater into an engineered channel that will also carry brook water to the mouth of Sydney Harbour. The tender closes Aug. 10. More than 70 per cent of the south pond, located between Prince Street and the Ferry Street Bridge, has been solidified and stabilized. Treatment of the entire pond is expected to be completed in August. It will be followed by the construction of a channel to allow brook water and groundwater to flow through the site and into the harbour. In January 2007, the government of Canada and province of Nova Scotia committed $400 million to ensure the Tar Ponds and Coke Ovens cleanup is completed by 2014.

S&S Work Restarts In South Pond

03/23/10 The Sydney Tar Ponds Agency is pleased to announce that the cleanup has kicked into high gear with the restart of solidification and stabilization in the south tar pond.

Contractors began the cement work today (Tuesday, March 23, 2010). The process includes using an excavator to mix cement powder into the contaminated sediment, similar to the way a baker mixes ingredients when making a cake. The contract requires that each completed cell meets established criteria for permeability, leachability, and strength. For more on this contract, please click here.

It's expected that the south pond (from Prince Street to Ferry Street Bridge) will be completely solidified and stabilized by the end of summer, 2010.
