(The former cooling pond is shown above. It is now a small, circular piece of property adjacent to the south Tar Pond. As the grass grows, the former cooling pond will disappear into the landscape.)
The Cooling Pond project is nearly complete. The old circular reservoir, built in 1912 to hold water once used in the steelmaking process at SYSCO, has virtually disappeared.
The $4 million project began by de-watering 3 million gallons, about 250,000 gallons daily, out of the cooling pond to expose sludge (about 1.5 metres deep) spread along the bottom of the structure.
The water was pumped to a permitted facility on the former SYSCO site for treatment. Once treated, the water was properly discharged.
The sediment was impacted by Total Petroleum Hydrocarbons (TPHs), Volatile Organic Compounds (VOCs), Polycyclic Aromatic Hydrocarbons (PAHs), and metals. In mid December, contractors started to Solidify and Stabilize the sludge, starting with a pilot-scale demonstration, followed by full-scale Solidification and Stabilization.
Existing structures, such as old piping and a pump house, were decommissioned and removed from the site.
Throughout the activities, the Sydney Tar Ponds Agency continued with its commitment to protect the community and the environment. The project had a comprehensive environmental management plan that included an extensive air-monitoring program and dust and odour controls. There was also a master health and safety plan to protect workers on site, and the health and safety of the public continues to be of prime importance to the Agency.
The cooling pond project is Nova Scotia's first aboriginal set-aside. The project provided bidders with majority aboriginal ownership and control the opportunity to benefit from cleanup work and to gain skills and training needed to compete for other construction projects.

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. Air monitors are operating in real-time at the project fence line, and also operating within the work site as part of the Master Occupational Health and Safety Plan for the project.
