The Government of Nunavut, Department of Community and Government Services, on behalf of the Municipality of Kimmirut, is applying for the construction of the new wastewater treatment facility (WWTF) and amendment of the discharge effluent limits in the existing water license 3BM-KIM1929 to effectively service the growing population in Kimmirut over a 20-year life span. The facility consists of a lagoon and wetland-treatment-area and will be designed to meet the long-term needs of Kimmirut and the regulatory requirements. The lagoon requires a working volume of 26,900 m3 based on projected annual wastewater generation until 2043.The treatment goals for the WWTF effluent criteria at the end of treatment are established as 100, 120 and 1.25 mg/L for carbonaceous biochemical oxygen demand (CBOD), total suspended solids (TSS) and un-ionized ammonia as nitrogen, based on a 6-year research project completed by Centre for Water Resources Studies at Dalhousie University. The licensee is requesting to remove the effluent quality limits from KIM-3 and to add limits to KIM-5 which does not currently have limits. Once the future lagoon is constructed KIM-3 will represent partially treated wastewater leaving the lagoon and KIM-5 will represent fully treated wastewater effluent at the outlet of the wetland-treatment-area. It is still recommended to sample KIM-3 for treatment monitoring purposes but no effluent parameter limits should be applied.The design consultant recommends that the effluent quality limits applied at KIM-5 be CBOD 100 mg/L, 120 TSS mg/L, and to remove faecal coliforms as a parameter since this is a public health parameter and not an environmental parameter. The receiving environment is zoned for waste disposal and not used by the public for fishing, harvesting, or recreation. Faecal coliforms are not included in the federal Wastewater Systems Effluent Regulations SOR/2012-139 Fisheries Act Registration 2012-06-29. Faecal coliforms are also no longer applied as an environmental parameter in the Northwest Territories where the Nunavut Water Board historically derives its effluent parameter decisions on.
