Dufferin Aggregates, a Division of CRH Canada Group Inc. - Issuance of a licence to remove over 20,000 tonnes of aggregate annually from a pit or a quarry

Dufferin Aggregates, a Division of CRH Canada Group Inc. has applied for a Class A licence (Category 3 – Pit Above Water) to excavate aggregate from a pit of 40.44 hectares in size with an extraction area of 30.15 hectares.

This application is for an expansion to the existing Aggregate Resources Act (ARA) licence No. 626112 (Dufferin Alps Pit) and existing ARA licence No. 626113 (Dufferin Cedar Creek Pit). It is proposed that all tonnage removed from the proposed licence and adjacent ARA licence No. 626112 and ARA licence No. 626113 will be combined for total annual tonnage of 1,500,000 tonnes.

Other information

Dufferin Aggregates, a Division of CRH Canada Group Inc. currently operates an adjacent site under the authority of licence No. 626112 under the ARA.  In total, 51.5 hectares are currently licenced as a pit. The annual tonnage condition is 1,500,000 tonnes in combination with licence No. 626113.

Dufferin Aggregates, a Division of CRH Canada Group Inc. currently operates an adjacent site under the authority of licence No. 626113 under the ARA.  In total, 53.28 hectares are currently licenced as a pit. The annual tonnage condition is 1,500,000 tonnes in combination with licence No. 626112.

The extraction of aggregate from a pit or quarry on private land designated by regulation, in the Province of Ontario, requires the issuance of a licence.  The Aggregate Resources of Ontario Provincial Standards Version 1 (Provincial Standards) sets out the application process and requirements.

For each new licence, the applicant must provide information (site plan, summary statement, technical reports) with respect to the existing features, operation and rehabilitation of the site to demonstrate that the proposed operation will minimize adverse impact on the environment.  This information is prepared in accordance with the category being applied for under the Provincial Standards.

For this proposal, the following information has been prepared and submitted to the Ministry of Natural Resources and Forestry:

• Site plan
• Summary Statement
• Natural Environment Level 1 and 2
• Cultural Heritage Stage 1 and 2 (Archeological Assessment stage 1 and 2) (Cultural Heritage Impact Assessment)
• Hydrogeological Level 1 and 2 (Hydrologic and Hydrogeological Study)
• Noise Assessment (Noise Impact Study)

The Site Plan addresses existing features of the pit and/or quarry area (existing natural features and land use on and surrounding the site within 120 meters); the proposed operation (shape, dimensions, area and depth to be excavated, method of extraction); and progressive and final rehabilitation.

The Summary Statement includes information on one or more of the following considerations:  land use planning, agricultural classification, quality and quantity of aggregate, haul routes, truck traffic and entrance permits, progressive and final rehabilitation, surface water, and elevation of the established groundwater table.

The Natural Environment report determines the presence of significant natural heritage features/areas and fish habitat and ensures that any necessary preventative, mitigative or remedial measures are undertaken for their protection. A Level 1 report identifies if the features are on-site or within 120 meters of the site.  If features are identified, then an impact assessment (Natural Environment Level 2 report) is prepared to determine any negative impacts on the natural features or ecological functions, and any proposed preventative, mitigative or remedial measures.

The purpose of a Cultural Heritage Resources report is to ensure that significant archaeological resources are identified, assessed for their significance, and protected (preserved or collected).

A Hydrogeological Level 1 report is a preliminary evaluation to determine the final extraction depth relative to the established groundwater table(s) and the potential for adverse effects to groundwater and surface water resources and their uses.  If the Level 1 report identifies a potential adverse effect resulting from the operation, then an impact assessment (Level 2 report) is required to determine the significance of the effect and the feasibility of mitigation.

A Noise Assessment report is prepared if extraction and/or processing facilities are within 150 meters (for pit applications) or 500 meters (for quarry applications) of a sensitive receptor defined by the Provincial Standards.  The report is required to determine whether provincial guidelines can be satisfied.

Comments received through the Environmental Registry should not be construed as an objection under the ARA in accordance with section 4.0 – Notification and Consultation Standards of the Provincial Standards 1.0 under the ARA.  To be considered as a formal objector, individuals need to contact the Ministry of Natural Resources and Forestry person specified on this notice to determine how to submit an objection.
