Final Completion Date April 5, 2010 Work Progress during January 2008 by Area or System: 1. General:

Western Water maintained the Storm Water Pollution Prevention Plan best management practices (BMPs). Western Water has submitted rain event inspection forms for the record. Western Water has continued routine weekly safety tailgate meetings, weekly safety checks, as well as the monthly safety audit performed by their safety officer. Reports of all these activities have been submitted for the record. Western Water conducted a Confined Space Entry safety class. This was coordinated with CMSA’s confined space program and Western Water has adapted their program to follow the more stringent guidelines. During this month Western Water has also submitted the revised Baseline schedule and monthly project photographs as required. The quarterly update of the “Dear Neighbor” letter was prepared for distribution. The website and progress photos were added to this update. A “First Scoop” drawing was held on January 23. With the help of the contractor’s operators, two CMSA staff members will operate an excavator and scoop dirt for the excavation work in the chlorine contact tank area, which is expected to occur in early February. On January 31, CMSA, Carollo, Harris & Associates, and Western Water representatives attended a half-day partnering session. All parties reviewed and re-established project goals.

2. Polymer Facility: Western Water has formed the walls for the sump pump and drain and the walls of the facility, backfilled and compacted aggregate base under the bottom slab. The bottom mat rebar was placed for the base slab. The electricians ran their conduit lines within the base slab area, prior to the concrete placement. The shoring for the sump area with the protective barrier fence remains within the roadway. Western Water also ran two 3-inch polymer lines, one 3-inch reclaimed water line and one 3-inch potable water line from the stubbed locations to the connection points in the Grit Chamber.

3. Gallery A & B Improvements, including Grit Chamber 3

Western Water continued work on the fire protection water line and began installation of the fire hydrant adjacent to the Headworks Building.

4. Primary Clarifiers 6 & 7

Subcontractor Condon-Johnson staged their storage van and rebar cages for the secant pile retaining wall along the plant road in the area of the new primary clarifiers.

5. Chlorine Contact Tanks 5 & 6 Subcontractor Stroer & Graff investigated and resolved the accident issue at the beginning of January. New safety goals were set for no injuries on the project. Stroer & Graff were allowed to continue installation of the shoring system in the chlorine contact tank and effluent pump station area. The beam installation is expected to be complete in early February and excavation of the area will begin shortly thereafter.

6. Effluent Pump Station

The activity in this area was the same as the activity in the chlorine contact tank area noted above.

7. Secant Retaining Wall and other Site improvements Subcontractor Condon Johnson began installation of the reinforced and unreinforced piles. Condon-Johnson completed the installation of the majority of the unreinforced piles within the first two weeks of January. This work involves drilling a hole to the required depth into the bedrock and filling it with unreinforced controlled low strength concrete. They also began installation of the reinforced piles between the unreinforced piles. This work involves drilling a hole to the required depth into the bedrock, placing a cylindrical reinforcing steel cage into the hole, then placing a large steel beam within the cylindrical rebar cage to within six inches of the bottom depth of the hole and filling the hole with plasticized concrete. The welding of Nelson Studs on the steel beams for the reinforced piles is on-going.

8. Review Item Summary

Please see attached RFI and Submittal logs in Section 3 for details of the following items. The majority of the certified payroll documents was received at the end of the month and will be reviewed and returned in early February.

1/22/2008 1/25/2008On Sheet S-9.5, Detail 2, the drawing show a typicalcantilevered parapet wall detail for the Chlorine ContactTanks. We propose to shorten the length of the hooksshown on the attached drawing. This will allow us tohave our wall forms unobstructed by these dowels. Wepropose to have hook lengths shorten as shown onAttachment A and similar to Detail AB on Sheet S-5.6 atthe Primary Clairifiers.

Thank you,

OPN00032 WESTWATR HARRIS Cantilevered ParapetReinforcement

1/31/2008 2/6/2008On sheet M-9.5 of the drawings typical detail S200 notesthat concrete will be chipped and hammered out anoversized hole in order to recover existing rebar andplace and grout a wall spool for the 16 inch 3 water pipeline to pass through the existing Chorine Contact TankWalls.

We propose to core drill a 20 inch hole for the 16 inchpipe. For each of the three interior walls we propose touse 1 link seal grouted in on both sides with 10,000 lbsgrout. For each of the two exterior walls we propose touse 2 link seals grouted in on both sides and betweenusing 10,000lbs grout. This is our recommendation.

Thank you
