What will happen with the existing Duntroon quarry?
The existing quarry will continue to be used for some time. It is hard to predict the exact 'life span' of a quarry since much depends on market demand and other factors. However, the existing quarry and new quarry will operate simultaneously for a period of time.

Is there a rehabilitation plan for the existing and proposed quarry?
Yes, all quarry licenses include a rehabilitation plan to be put into place when the quarry eventually stops operating. The rehabilitation plan for the existing Duntroon quarry is for it to become natural/conservation land. The quarry itself would gradually fill up and become a lake, although that could take approximately 30 to 40 years. In the last three years Georgian has done progressive rehabilitation at the existing quarry, including tree plantings along the southern berm.

A rehabilitation plan for the proposed quarry is being developed as part of the site license application.

What is de-watering?
The proposed quarry would be mined to a depth of approximately 39 metres (to be confirmed through geologic testing), which is below the water table. This means that the quarry has to be 'de-watered,' which is a process to drain the water out of the bedrock so that a dry quarry floor is achieved to permit operations.

De-watering is achieved by pumping groundwater. Typically, water that is pumped is collected in a settling pond on the quarry floor. Particles or suspended solids then settle to the bottom of the pond and the water that is discharged is clean. The water is discharged to a defined outlet, such as a municipal ditch or nearby creek. Defining where the water is discharged is part of the water resources impact study.

How far from the proposed quarry property does the water testing take place?
Water testing (of surface and groundwater) takes place at least as far as Concession 10 to the east and the same distance to the west, north and south of the property. It's recognized that there are a number of springs along the lower sections of the Niagara Escarpment, and these areas will all be investigated as part of the water resource study and monitored on an ongoing basis for the life span of the quarry.

How can the general public get involved in the application process?
There are several ways for neighbouring residents or others to keep up-to-date, ask questions and provide input on the planned expansion. They include:

Open houses will be scheduled on a regular basis throughout the course of the application process.

A project committee comprised of neighbours and Georgian representatives has been formed and will meet throughout the course of the application process.

A newsletter, Stepping Stones, is published quarterly.

Questions may be asked through this web site (FAQ).

Individual meetings can be held with Georgian representatives to discuss concerns and answer questions. Neighbours are welcome to have Georgian representatives visit their properties to discuss specific issues.

The authorities involved will hold public meetings as they consider project applications, e.g. Township of Clearview, Niagara Escarpment Commission and Ministry of Natural Resources.

Neighbours and others are welcome to contact Ken Lucyshyn, vice president and general manager of Georgian Aggregates and Construction, at any time (705) 445-2300, extension 224, or klucyshyn@walkerind.com.
