Our vision

Our Vision

At Lafarge, responsible environmental management is central to our success as a leading aggregate mining company, and we seek to continually improve our performance. Environmental Management Systems at our operations help us to achieve our goals of protection and stewardship. Performance indicators help us measure how well we have done. We take a precautionary approach throughout the life of a site by assessing potential impacts and evaluating how to avoid, mitigate, or control these impacts.

Biodiversity

The Lafarge Dundas Quarry is in the final stages of a voluntary Biodiversity Plan that will be incorporated into its site operations. Several restoration and enhancement initiatives are proposed to enhance the ecology of the site, by connecting different habitats. The main objective for the Dundas Quarry is to create a network of water bodies and landscapes that complement and connect with the surrounding landscapes. Extraction areas can be rehabilitated in a variety of ways – such as large lakes with shallow wetlands along shorelines, varied cliff faces, vegetated side slopes, and the establishment of smaller open areas. Rehabilitation will complement the local system, and plant species native to the Hamilton area will be used.

Lafarge works cooperatively with the Hamilton Conservation Authority and provides water to the surrounding environment when requested. We value these partnerships and aim to help increase biodiversity efforts to protect the health, integrity and sustainability of the local watershed.

Air Emissions Management

Dust is the most common air emission at aggregate mining operations. Lafarge suppresses dust emissions from roads, crushers and conveyor belt systems through the application of water to roads, the operation of mist sprays and dust collection systems at sources. An aggregate conveyor system was installed to connect the North Quarry to the Processing Area. The 3.2 kilometre conveyor system mitigates the use of haul trucks minimizing road dust. We have a Fugitive Dust Management Plan and we use water cannons to mitigate dust during blasting and in areas where the water trucks cannot attend.

Blast and Noise Management

At Lafarge, we hire a third party expert for blasting services and every blast is designed by an engineer and monitored with seismographs. We use state of the art detonators on delayed response to minimize impacts. If you are a neighbour and are interested in blast notification, please contact us and we would be pleased to add you to a blast notification call list.

Our processing equipment is enclosed to reduce noise and dust. A 3.2 kilometre conveyor belt minimizes truck noise from travel, and we use new directional back-up beepers to reduce sound impact where trucks are needed. The primary crusher in the North Quarry was installed underground to reduce noise. In addition, we have installed rubber liners on the screens and truck boxes to further reduce noise impacts while loading material.

Water Management

At Lafarge Dundas, we do not chemically process our products. To minimize water use, we have installed closed circuit water use systems to reuse and recycle the water that we need to operate. We have an extensive monitoring program in place to monitor the groundwater table as the operation proceeds, and report all water use under our permitted sources to the Ministry of the Environment. If you have a question about your well and our operation, please contact us.

Rehabilitation

Our aim is to leave behind land that will support productive future use. When Lafarge took ownership of the Dundas Quarry in 1998, there were vast areas within the North and South Quarries that were already disturbed. Since that time, we have developed a mining plan that focuses on complete extraction and rehabilitation in the North Quarry, to ensure that environmental impacts are effectively addressed. As part of our current North Quarry Extension, we worked extensively with government agencies to improve our existing North Quarry rehabilitation plan and are now working towards implementing that future vision.

During operations at the Dundas Quarry, a progressive rehabilitation approach is employed. As soon as feasibly possible, disturbed areas (in the form of side slopes no longer needed for active mining) are contoured and vegetated.
