Cultural heritage evaluation report consultation
The Ministry of the Environment is consulting the public for 60 days on the findings of a cultural heritage evaluation report of the Deloro mine site. The comment period ends June 26, 2012

Tailings area cap 80 per cent complete
Construction on the engineered cap on the tailings area is now nearly 80 per cent complete. The construction, which began in April 2011, was awarded to Golder Construction Inc., with another contract awarded to McIntosh Perry Consulting Engineers Ltd. to act as contract administrator. Both contractors were chosen through a competitive procurement process.
Three caps to cover contaminated waste
This is the first of three engineered covers planned for the site. The purpose of the caps is to cover contaminated wastes, isolating and containing them to ensure the site is safe for people and the environment.
The engineered cap on the tailings area consists of 122,000 tonnes of sand, 186,000 tonnes of soil, and 250,000 square metres of engineered fabrics (enough to cover 40 football fields).
The contractor will return in the spring to plant nearly 20,000 hybrid poplar trees on the cap as part of the planned remediation strategy. At that point the construction of the tailings area cap will be complete.
Next phase of construction began in January
The ministry has awarded a contract to CSS Corporation, through its division, HAZCO Environmental Services to prepare the industrial and mining area for construction of an engineered cover. Genivar Inc. is the contract administrator.
This is the first of three stages of work happening in the industrial and mining area. Work began in January 2012 with tree clearing and grubbing, and construction of a clay berm, which will be the footprint of the cover. Work on this stage of the project will continue until summer 2012.
Dust control and air quality monitoring during construction
Dust control measures will be in place throughout construction. The contractor will use water and other dust suppressants on roads and disturbed soil. Work will be minimized in periods of high winds.
During construction the contractor will monitor air quality at four locations around the industrial and mine area.
What is the Deloro Mine Site Cleanup Project?
The project deals with the complex legacy of environmental contamination caused by the former owners of this historical mining, refining, and manufacturing site at Deloro, Ontario.
The Ministry of the Environment assumed responsibility for this site when the owner failed to comply with orders to stop pollution. The ministry has made significant progress in dealing with the complex and multi-faceted environmental issues at the site, and has significantly reduced the amount of arsenic coming off the site.
Where is Deloro?
The Deloro Mine Site is in eastern Ontario about 200 km southwest of Ottawa and 65 km east of Peterborough. The site sits along the banks of the Moira River, beside the eastern boundary of the Village of Deloro (pop.180).
Key actions to date
- Arsenic Treatment Plant collects and removes arsenic from contaminated groundwater under the site.
- Abandoned mine shafts have been located and sealed.
- Deloro Village Environmental Health Risk Study found the adjacent village of Deloro safe.
- Moira River Study found no adverse effect on aquatic ecosystem. The Moira River is safe to swim in.
- Public consulted on final cleanup plan — with extensive public consultation in 2005.
- Federal environmental assessment was completed and approved in 2009.
- Access road upgrade between Highway 7 and the tailings area were completed January 2011.
- Tailings area engineered cover — started March 2011.
