3 What this means and what it doesn t This means we will: Excel at managing both the quantity and quality of water we use, reuse and return. Have a detailed understanding of our impact on the water resources we draw from and return to, as well as the net environmental effects of water management. Maximize recycle and reuse of water without detrimentally affecting other key environmental areas such as GHG s, land and water reclamation (salinization), and increasing waste. This does not mean we will: Increase recycle rates to 100% and decrease use intensity to zero.

4 Scope All sources of make-up water used in the oil sands including groundwater, the Athabasca River watershed, as well as reporting on or monitoring any effects on these from withdrawal and return of water. Virtually all surface facilities for both the mining and in situ sectors such as steam generators, water treatment facilities like heat exchangers, filters and treatment vessels. The use, reuse (recycle), treatment, conditioning, disposal, storage including surface storage in raw water ponds, surface water management, tailings ponds and pit lakes for mining and extraction, in situ, and upgrading facilities. Modeling of water chemistry, groundwater sources and disposal areas, models for quantity and quality of water in the Athabasca River watershed are in scope including models for both the operations, and reclamation phases of oil sands leases. Regional water management such as sharing water between mining and in situ operations, and release of water to the environment.

5 In Situ Water Performance Goal The In Situ Performance Goal is a measure of intensity, meaning the chosen metric is presented in relation to one barrel of bitumen produced. The measure will enable the public to see how much water COSIA members are collectively using to produce their bitumen. Performance against the goal will be reported publicly on an annual basis.

6 How COSIA members will deliver COSIA members are developing new technologies and sharing best practices to enable further reductions in fresh water use. There are a number of specific areas COSIA members are focusing on to deliver this 50 per cent reduction: Improving water treatment processes. Improving steam quality and generation efficiency. Reducing boiler blowdown waste and improving disposal techniques.

7 Key Projects to Deliver Performance Goal Improving water treatment processes: Water Technology Development Center, Organics Characterization and Fouling Gen II In Situ Water Treatment, Zero Lime Softening, and Vibratory Shear Enhanced Process. Improving steam generation efficiency: Boiler Blowdown Reduction Technologies, Direct Contact Steam Generation, Rifled Tubes, and Boilers in Series. Reducing boiler blowdown waste and improving disposal techniques: Regional Water Management Initiative, Key On-going Completed Reduced Liquid Discharge, Evaporator Waste Solidification, and Long-term strategies for blowdown management.

8 Opportunity Areas In Situ and Mining Steam Generator Performance: Generate higher quality steam with lower GHG intensity, reduced disposal volumes, improved recycle, lower costs. Water Treatment Performance: Improve the environmental performance of the water treatment unit processes. Residual Management: Determine best long-term strategy for management of boiler and evaporator blow down streams. Water Reclamation: Water return to natural surface waters during operations to decrease net use of water and improve the quality of the reclamation landscape. Pit Lakes: Demonstrate that pit lakes will successfully remediate water quality and provide suitable, healthy aquatic ecosystems. Watershed Cumulative Effects: Track and assess water quality changes due to the oil sands operations and prevent associated changes to aquatic biodiversity.
