Brant County wants to see an impact study of potential silica at Dufferin Aggregates’ proposed sand and gravel pit near Paris, Ontario, the Brantford Expositor reports.
The study would take place at a proposed 600-acre-plus area where Dufferin, a division of Holcim (Canada) Inc., wants to open as a sand and gravel pit later this year or sometime next year.
The county sent a letter to the Minister of Natural Resources to request the study after Dr. Malcolm Lock, the medical officer of health heading research about potential silica at the site, made a recommendation that the county do so.
The request comes after a group opposing the pit — Concerned Citizens of Brant (CCOB) — noted concerns about the effects of silica on the water supply in Paris.
The county may require Dufferin to fund the study.
Lock told the Brantford Expositor that he has found someone willing to test any data provided. Lock added that he “would not expect the results of such analysis to show a link to any short- or long-term human population health hazards”
Kevin Mitchell, Dufferin Aggregates’ manager of environment and properties, said in the report that Dufferin already has several aggregate operations running in Brant and that there are no known silica concerns related to those operations.
Mitchell also noted that dust control is regulated by legislation, adding that the study is not necessary. He said the site will include multiple measures to control dust, including “MOE-approved dust suppressants, progressive rehabilitation, berms and tree screens.”
