3. 3 Alaska Significant Resource Potential in NWT, Canada

4. 4 NWT YK BC AB Beaufort Sea AK YK NWT Central Mackenzie Valley Beaufort: on, near, and offshore Mackenzie Valley - NWT AK

5.  Significant O&G potential in NWT: onshore, near-shore, offshore  Historically: reliance on municipal infrastructure for industrial waste  Existing NWT infrastructure does not meet industrial needs  Government, Land Claimants, Stakeholder concerns: ◦ Waste management for on-shore, near-shore and off-shore upstream oil and gas ◦ Various waste streams, substantial quantities ◦ facilities not designed, managed or licensed to accommodate ◦ Regulatory jurisdiction and requirements unclear ◦ Coordination of treatment/disposal lacking ◦ No integrated regional approaches  May result in adverse and unacceptable environmental economic effects/liabilities to NWT communities, governments  Future development exacerbates challenges  Result: determining approaches to waste management one of the most controversial and time-consuming aspects of planning, assessments and reviews… 5 ESRF NWT Upstream Oil & Gas Waste Stream Study: ESRF NWT Upstream Oil & Gas Waste Stream Study: Regional Waste Management Modelling Tool - RWMTool

6. 6  O&G Waste Management identified as priority: ◦ Consultations in regional planning processes:  Beaufort Sea Strategic Regional Plan of Action  Beaufort Basin Regional Environmental Assessment  Significant during Joint Review Panel for proposed MGP  Regional Waste Management?  Requirements: ◦ Assess immediate and long-term regional management issues and options resulting from waste production and disposal  Infrastructure, transportation ◦ Where? On-shore, near-shore and off-shore in the NWT  Inuvialuit Settlement Region (ISR)  Gwich’in Settlement Area (GSA)  Sahtu Settlement Area (SSA) ESRF NWT Upstream Oil & Gas Waste Stream Study: ESRF NWT Upstream Oil & Gas Waste Stream Study: Regional Waste Management Modelling Tool - RWMTool

7. 7  Environmental Studies Research Funds (ESRF): ◦ Initiated in 1983, receives its legislative mandate through the Canada Petroleum Resources Act (CPRA) ◦ Designed to assist in the decision-making process related to O&G exp. and dev. on Canada's frontier lands ◦ Frontier lands: where Canada has the rights situated in areas north of 60 degrees, and offshore of Canada's East and West Coasts ◦ Sponsors environmental and social studies pertaining to petroleum exploration, development, and production activities on frontier lands. ◦ Funding provided through levies on frontier lands paid by interested holders; i.e. O&G companies ◦ Directed by joint government/industry/public management board ◦ Administered by secretariat, in Office of Energy Research and Development, Natural Resources Canada, Ottawa, Ontario Project Concept and Proposal developed, submitted to ESRF…… ESRF NWT Upstream Oil & Gas Waste Stream Study: ESRF NWT Upstream Oil & Gas Waste Stream Study: Regional Waste Management Modelling Tool - RWMTool

8. 8 Technical Objectives:  Combine waste streams, and projects over regional temporal and spatial boundaries  Built on database(s)  Waste stream types (WS) and quantities  Waste factors (WF)  Infrastructure and Design Standards in a Searchable Database  Simulate development scenarios projected over spatial and temporal boundaries ◦ Compare:  Mass balance scenarios over regional temporal and spatial boundaries  Infrastructure and Design Standards Develop info, options…………… ESRF NWT Upstream Oil & Gas Waste Stream Study: ESRF NWT Upstream Oil & Gas Waste Stream Study: Regional Waste Management Modelling Tool - RWMTool
