  1. Type ‘A’ Water Licence ApplicationDepartment of Community andGovernment Services,Government of Nunavut Sewage Treatment and Water SupplyHamlet of Rankin Inlet By Jim Walls, P.Geo. Nuna Burnside Engineering and Environmental Ltd.

  2. Licence Components • CGS operates the water supply and sewage treatment infrastructure in Rankin Inlet – which are the subjects of this application • All other NWB regulated infrastructure and operations in Rankin inlet are licensed by the Hamlet or other parties

  3. Application History • Original Type ‘B’ Licence issued in 2002 • Expired November 2007 • Type ‘A’ Licence now required due to the size of the Hamlet and water usage • Type ‘A’ application includes a Public Hearing

  4. Supporting Documents • Operation and Maintenance Plan • Emergency Contingency Plan • Monitoring and QA/QC Plan • DFO intake guidelines assessment • Various engineering plans and reports

  5. Agency Review • The application and supporting documents reviewers included: -Nunavut Water Board (NWB) - Environment Canada (EC) - Indian and Northern Affairs (INAC) - Fisheries and Oceans Canada (DFO) -GN – Department of Environment (DOE)

  6. Sewage Treatment Facility • Utilidor and trucked sewage • Sewage treatment plant operation • Discharge of treated effluent to Hudson Bay • Disposal of sewage sludge at the Hamlet landfill site

  7. Sewage Treatment Facility Issues • Effluent discharge quality • Impacts of the effluent discharge on the marine environment • Sewage sludge disposal agreement with the Hamlet

  8. Addressing the Issues • Consulting engineers are working on design modifications to upgrade the plant and improve effluent quality • An environmental consulting company specializing in marine environments has been retained to study discharge impacts • The Hamlet and GN have agreed on a draft waste disposal agreement

  9. Requested Conditions – Plant Upgrades • Submit an engineering report outlining the proposed Sewage Plant upgrades and expected improvements to effluent quality by December 31,2010 • Submit a schedule for constructing the upgrades by December 31,2010

  10. Requested Conditions – Marine Impacts • Submit a report on the findings of the Marine Impact Study including conclusions and recommendations by December 31,2010 • Submit a schedule to conduct action as per the recommendations by December 31,2010

  11. Requested Conditions – Sludge Disposal • Submit a copy of a written agreement with the Hamlet for the disposal of sewage sludge in accordance with applicable waste disposal regulations by December 31,2010

  12. Water Treatment Facility • Nipissar Lake source • Pipeline to reservoir • Storage and treatment • Distribution system • NWB licence is focussed on environmental impacts of the system not the quality of the delivered water

  13. Water Intake Facility Issues • Amount of water pumped from the lake needs to be accurately determined • Impacts to Nipissar Lake due to drawdown needs to be assessed • Sustainability of supply needs to be determined • Impacts to fish habitat needs assessment

  14. Addressing the Issues • A consulting engineering firm was retained in 2009 to conduct studies and evaluate impacts of withdrawals including: - current and projected volumes -distribution system losses -impact on Nipissar lake and recommendations for additional supply

  15. Requested Conditions • Submit an assessment of the water supply capacity of Nipissar Lake and a detailed assessment of Hamlet water supply requirements for the future including conclusions and recommendations by December 31,2010 • Submit a schedule to address recommendations by December 31,2010

  16. Summary • CGS is requesting a Type ‘A’ NWB licence for water supply and sewage treatment • Documents outline the information available and provide detailed plans to operate the facilities and address data gaps • Recommended ‘Conditions’ include a realistic schedule

  17. Input from Elders needed • Have you seen any impacts to fish, marine mammals or water quality from the sewage discharge? • Have you seen any impacts on the water levels in Nipissar Lake caused by taking water for the Hamlet?

  18. Questions and Comments? • Thank you - Qujannamiik
