10 Water Supply Reliability Expanding Surface Water Treatment Plant from 16 MGD to 21 MGD  New Membrane Treatment Modules  Additional Treated Water Pumping Capacity  Additional Chemical Treatment and Air Handling Expected Completion Plant Expansion May 2008

11 Water Supply Reliability  Water Rights Permit Extension Filed with Department of Water Resources  CEQA Process Underway to Support Permit Extension Request  Expected Completion Late 2008

12 Water Supply Reliability Participating in Regional Activities  Briefings with Congressional Representative  Briefings with State Government Representatives  Briefings with County and Local Representatives  Sacramento Groundwater Authority Contamination Task Force  ACWA Cap to Cap Outreach

13 GET “L-A” and “L-B” Remediation  GET “L-B” – Bajamont Site Operational at 600 gpm and Discharging to the American River  GET “L-A” – Design Underway with Irrigation Reuse (1MGD) and Wet Weather Discharge to American River

15 GET Treatment Process Summary Bajamont GET “L-B”Ancil Hoffman GET “L-A” Initial Extraction Rate325 gpm600 gpm Revised Extraction Rate 600 gpm800 gpm Plant Design Capacity1,000 gpm2,000 gpm Contaminants Present Now NDMANDMA, Perchlorate, TCE Contaminants Expected NDMA, Perchlorate, TCE Treatment ProcessesUV, GAC, (F) Ion Exchange, (F) Peroxide UV, Peroxide, (F) Ion Exchange, (F) GAC

16 Bajamont GET “L-B” Update  Bajamont GET “L-B” Facility Construction complete – Startup Extraction Well September 7, 2007  Construction met date set by EPA  “Operational and Functional” Certification by EPA Pending Completion GET “L-A”

17 Bajamont GET “L-B” Facility Sample Heading  First level bullet Second level bullet –Third level bullet

18 Bajamont GET “L-B” Facility Sample Heading  First level bullet Second level bullet –Third level bullet

19 Bajamont GET “L-B” Facility Sample Heading  First level bullet Second level bullet –Third level bullet

20 GET “L-B” Completed

21 Ancil Hoffman GET “L-A” Update  Design started at same time as GET L-B but separated to allow public outreach and siting process in Ancil Hoffman Park to proceed at a slower pace  Milestone Achieved August 8, 2007: Ancil Hoffman GET “L-A” Facility location approved by County Board of Supervisors

22 Ancil Hoffman GET “L-A” Update  CWD Participation includes Buried Reservoir and new Irrigation Pump Station for Golf Course  Reuse of Remediated Groundwater offsets surface water and maintains beneficial use of groundwater  Construction Buried Reservoir estimated to start Summer 2008

23 Strategic Goals 1. Early Detection & Identification of Contaminants Near Our Water Supply Wells. 2. Expansion of the Bajamont Water Treatment Plant. 3. Assist Aerojet in Locating, Permitting Remediation Facilities. 4. Using Treated, Extracted Groundwater at Ancil Hoffman Park.

24 Strategic Goals 5. Increased Conservation Efforts to Reduce Overall Demand. 6. Identify Potential Funding Sources for Projects. 7. Work Regionally to Enact Legislation to Increase Funding to Expedite Remediation Efforts. 8. Legal Representation.
