St Mary's Cement Inc. (Canada) - Issuance of a licence to remove over 20,000 tonnes of aggregate annually from a pit or a quarry

St. Marys Cement Inc. (Canada) has applied for a Class A licence, Pit/Quarry Below Water, to excavate aggregate from a pit/quarry of 261.2 hectares in size with an extraction area of 199.5 hectares.

This application is for the establishment of a new pit/quarry. The annual tonnage condition applied for is 2,500,000 tonnes.

Other information

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. Ontario Regulation 244/97 and the Aggregate Resources of Ontario Standards set 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.

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

• Site plan
• Planning Justification and Summary Statement
• Natural Environment Report
• Cultural Heritage Report
• Maximum Predicted Water Table Report
• Water Report
• Noise Assessment Report
• Blast Design Report
• Agricultural Impact Assessment Report
• Visual Impact Assessment Report
• Socio Economic Assessment Report
• Traffic Impact Study
• Air Quality Impact Assessment

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 identifies the presence of significant natural heritage features/areas that exist on the site or within 120 meters of the site. Where any of the features or areas have been identified, the report must identify and evaluate any negative impacts on the features or areas and ecological functions, and identify any proposed preventative, mitigative or remedial measures. The report must also identify if the application site or any of the features are located within a natural heritage system that has been identified by a municipality in ecoregions 6E and 7E or by the province as part of a provincial plan.

The Cultural Heritage Report must be consistent with provincial requirements under the Ontario Heritage Act and the Provincial Policy Statement. Screening checklists evaluating the potential for archaeological resources, built heritage and cultural heritage landscapes, with supporting documentation, is required. Where screening indicates that assessments are requirement to be completed, the assessment reports and letters from the Ministry of Heritage, Sport, Tourism and Cultural Industries must be obtained.

A report must be prepared that details how the maximum predicted water table is identified in metres above sea level, relative to the proposed depth of excavation at the site. Applications proposing to excavate below the maximum predicted water table must complete a Water Report. Level 1 determines the potential for impacts to ground water and surface water resources and their uses. If the Level 1 identifies a potential for impacts resulting from the operation, then an impact assessment (Level 2) is required to determine the significance of the effect and potential for mitigation.

A Noise Assessment report is prepared if proposed excavation and/or processing facilities are within 150 meters (for pit applications) or 500 meters (for quarry applications) of a sensitive receptor. The report is required to determine whether provincial guidelines for Stationary and Transportation Sources can be satisfied.

A Blast Design report is prepared if a sensitive receptor is within 500 metres of the limit of excavation for a Class A quarry application. The report is required to demonstrate that provincial guidelines for blast overpressure and ground vibration can be satisfied.

An Agricultural Impact Assessment Report is completed in accordance with provincial guidance where a provincial plan requires such an assessment in prime agricultural areas.

The Ministry reviews all comments received through the Environmental Registry and the notification and consultation process under the Aggregate Resources Act (ARA), and considers them before making a decision. Comments received through the Environmental Registry are considered by the Ministry however, the process under the ARA is proponent driven. This means that comments for consideration by the applicant under the ARA process must be submitted to the applicant and the Ministry during the 60-day consultation period initiated by the applicant.

Details of the application process can be found in Ontario Regulation 244/97 under the ARA and on the Ministry website at aggregate resources|ontario.ca. Many regulatory changes for new applications took effect on April 1, 2021. This means that applications submitted after March 31, 2021 must meet the new requirements in Ontario Regulation 244/97 and Aggregate Resources of Ontario Standards.
