NOVA SCOTIA — Pictou Landing First Nation has asked the Federal Court to overturn Ottawa’s approval of a plan to store contaminated sludge from Boat Harbour in an enclosed structure on nearby land. The Mi’kmaw community in northern Nova Scotia has filed for a judicial review of the decision from federal Environment Minister Steven Guilbeault. Guilbeault said last month that the proposed remediation of Boat Harbour, which for decades received wastewater from a kraft paper mill, “is not likely to cause significant adverse environmental effects.” …The submission mentions insufficient consultation, interference with treaty rights and violations of the United Nations Declaration on the Rights of Indigenous Peoples, among other grounds. …Community members have said they were duped into the deal with false assurances that the effluent wouldn’t be harmful, but they soon noticed major environmental changes.
