The province has issued an Environmental Assessment Cerificate to Graymont Quarry and Lime Plant project, located about 30 kilometres of the city. Graymont will have to meet 25 conditions set out by the province. The project will require various federal and local government permits to proceed. The Giscome project is estimated to operate for at least 50 years. The project will initially extract up to 600,000 tonnes of limestone per year.
