SAFETY

Reporting period is

Regulatory Agency Visits occurring in period: = 1

May 2013

Orange County Health Care Agency performed a site visit on 5/8/2013 to observe handling of contaminated soils in the SEFE Area. They were satisfied with compliance to the agreed plan.

There were no Cal-OSHA safety visits made to the construction project site during the month of May.

The CM Team Site Safety Walk was conducted weekly in May 2013.

As of May 31, 2013, the project completed 590 days without a lost-time injury or recordable incident.

Operational incidents: None in May 2013

Health and Safety Plan (HASP) Update:

The Contractor put a new HASP in place for earthwork in the SEFE Area due to pesticide contamination of the upper three feet of soils. By the end of May a Contaminant Reduction Zone was established in the northwest corner of the work area to control ingress/egress and provide a place for workers to take breaks.

CONSTRUCTION CONTRACTOR ACTIVITY/ KEY ACCOMPLISHMENTS IN REPORTING PERIOD

MF Facility: Concrete work for the MF basement expansion advanced throughout May 2013. Four placements were made on train C cell bottoms and shelves. As of May 31, 2013, forms for the first high cell walls were being readied for close-up.

Electrical cable tray and conduit installation continued in the MF basement and in the east and west electrical rooms.

Mechanical piping for the two new Train E cells continued in May and new filtrate pumps were placed. However, on May 14, 2013, the CM discovered that welding on Siemens stainless steel piping delivered in April 2013 was non-compliant. Train E effluent piping was partially disassembled to investigate and several pieces removed for rework.

Backfill to elevation 10.0 was authorized by RFI and commenced May 20, 2013.

RO Building: Steel erection completed at RO on May 21, 2013. Metal roof decking installation commenced May 16, 2013.

Preparation and priming of steel connections by the coatings subcontractor followed behind completed steel framing and preparations for structural coatings followed behind decking installation.

More deliveries of large diameter FRP piping were received and stored on the north side of the new building, awaiting delivery of the pipe supports and access to the basement after structural painting completes.

Electrical cable tray installation began in the RO basement in May 2013.

UV Area: Canopy steel erection commenced May 9, 2013 and completed May 21, 2013. The Steel Subcontractor, Allied Steel, demobilized May 22, 2013.

Touch-up painting of steel connections followed.

SEFE Construction: The SEFE tank pads were completed April 3, 2013. No follow-on tank construction work occurred in April or May 2013, as the Contractor continued to redesign the foundation. On May 1, 2013, the Contractor submitted RFI 0589 requesting a reduced factor-of-safety for pile design based upon the results of the April 15 field re-test. Approval was granted May 2, 2013. The revised tank foundation design was submitted May 17, 2013. On May 30, 2013, the Design Engineer issued review comments that precipitated a teleconference. Supplemental calculations were subsequently submitted May 31, 2013.

From April 29 through May 1, 2013, the second-tier hazardous waste subcontractor, AIS, excavated the upper three feet of the SEFE Tank inlet/outlet piping area so that this area could be deemed uncontaminated. The contaminated spoils were stockpiled in the staging area westerly of Tank No. 1. Three thousand eighty-one (3081) tons of contaminated soils were loaded and hauled off to the Yuma, Arizona landfill from May 7 through May 14, 2013.

On April 27, 2013, excavation for the SEFE Pump Station and Meter Vault began in uncontaminated soils three feet beneath original ground surface. Uncontaminated soils were stockpiled on a PVC liner placed over the SEFE Tank No. 2 pad. These soils were later used for backfill at the MF.

Crushed rock was placed at Meter Vault subgrade May 10, 2013 and on May 28, 2013; the Meter Vault slab-on-grade was placed.

Soldier piles for shoring the SEFE Pump Station were installed May 22 and 23, 2013. Pump station excavation proceeded May 24, 2013; however, groundwater began seeping into the excavation. On May 28, 2013 the excavation was backfilled up to the top of pile elevation to prevent undermining of slopes. The dewatering and shoring systems are being re-evaluated by the Contractor.

Lime/Decarb Area: Change Order work to relocate the Lime Sludge Pig Station was implemented between late April 2013 and May 6, 2013. The cut-over to the new lime sludge alignment was conducted between May 7 and 9, 2013, clearing the way for auger-cast pile installation.

On May 20, 2013, the shoring pile rig mobilized and soldier piles for the new Finished Product Water (FPW) Channel were installed the next day.

On May 23, 2013, the auger-cast pile drill rig mobilized to the Lime Saturator Area. Pile drilling for the new saturator commenced May 30, 2013.

Chemical Storage Facilities: A Non-Conformance Notice was issued for the new SHC Storage Tank on April 30, 2013 due to a crack in the tank and several damaged outlets. The Tank had been damaged in transit to the job site. After an exchange of correspondence regarding repair procedures, the Contractor is planning to have the Tank picked up and returned to the manufacturer for repairs or replacement.

Electrical conduit rough-in advanced in the Sodium Hypochlorite Area 410 throughout May 2013.

Screenings Facility: New water piping for Screen No. 5 was installed.

Startup Planning: A workshop to discuss the overall startup plan for the expanded facility was conducted May 14, 2013.


MAY 2013

SIGNIFICANT SCOPE ITEMS/ISSUES

Contaminated Soils: On December 5, 2012, the Contractor notified the CM of potentially contaminated soils at SEFE and MF. Several months of sampling, testing and coordination with the Orange County Health Care Agency and Regional Water Quality Control Board culminated in the issuance of a Soils Removal Plan on February 7, 2013.

Several meetings to discuss the path forward were conducted in February and March of 2013. On March 22, 2013, the Contractor submitted two cost proposals, referred to as Phase A: one for building the SEFE Tank Pads as a lump sum, and the second for exporting up to 6000 tons of contaminated soils to a properly certified landfill at a unit rate. Two field change orders have been approved in Contract Change Order No. 8, in the amount of $622,739.

On March 25, 2013, a second-tier subcontractor that is licensed to handle and haul hazardous materials mobilized to begin grading the SEFE Area. Tank pads were completed April 3, 2013 and 2100 tons of contaminated soils were removed from the site by April 13, 2013.

On April 23, 2013, a meeting was held to present the Contractor’s proposal for Phase B. That same day, the earthwork subcontractor built an access road to the SEFE pumps station. On April 29, the CM issued a T&M field change order for the Phase B work proposed to be performed by the second-tier hazardous materials subcontractor as excavation of contaminated soils over the tank inlet/outlet piping area. On April 30, 2013, the Contractor issued a change Proposal Request (CPR) for the Phase B work discussed at the April 23, 2013 meeting.

The excavation of contaminated soils from the inlet/outlet piping area and area northerly of SEFE Tank No. 1 was completed May 1, 2013 and 3081 tons of contaminated material was hauled off by May 14, 2013. The General Contractor began setting up a Contaminant Reduction Zone in accordance with their HASP in the last week of May 2013.

MF Scour Air Piping: MF blower piping arrangements were determined to be incompatible with the control scheme for MF cell backwash. As a result, design changes have been made, revising piping, instrumentation and control points. Due to the stainless steel piping materials and the associated programming, the cost for this change will be significant. The Request for Proposal (RFP) was originally issued for this work on March 27, 2013. The Contractor submitted an RFI in regard to the scope in early May and a revised RFP is being prepared by the Design Engineer.

MF Basement East Cable Tray, Ductwork and Pipe Supports: On May 13, 2013, the CM responded to RFI 0579 seeking clarification of conflicts among


MAY 2013

File: 320.05 -2-

existing and proposed arrangements in the existing MF basement corridor that will serve the new Train C. The response provided sketches of changes to be made with notification that and RFP would follow. As of May 31, 2103, the RFP document is remained in development. This change impacts several trades and is complicated by the congestion of infrastructure in the basement.

Sulfuric Acid Piping: As a result of operational issues with the current sulfuric acid feed system, the Water District has requested changes to the suction piping design. The valves required for this change will take several months to procure and the cost associated with this change will be significant. The RFP for this change was issued March 12, 2013, and no proposal has been received as of May 31, 2013.

UV Electrical Building Conduit Routing: It was documented through RFI’s in April 2013 that existing underground electrical arrangements accessing the UV Electrical Building do not match those anticipated in the design. RFP 0118 was issued April 23, 2013, to revise the design. It was subsequently determined that the congestion of underground conduits complicates the proposed scope of RFP 0118. Currently, the CM and Contractor are investigating conditions to identify workable arrangements.

Energy Recovery System (ERS) Programming: On May 17, 2013, an RFP was issued for changes to the programming of the ERS to accommodate the external backpressure control valve recommended by the Energy Recovery Device manufacturer. This change in scope was identified through the submittal process and accepted as an improvement to the reliability of the specified system. Additional programming effort, documentation and testing is required of the Process Controls System Integrator, KDC.

QUALITY ASSURANCE/QUALITY CONTROL

Non-Compliances (NCN’s)

NCNs #11 -13 for low 28-day strength of concrete were issued in April 2013. By the end of May samples from the two of the deficient placements achieved design strength and the third was accepted by the Design Engineer as adequate for the actual load conditions. Concrete testing of adjusted mixes are breaking much higher, and the concrete quality issues have been closed.

NCN #14 was issued 4/30/13 for damage incurred by the new SHC Tank prior to its delivery April 17, 2013. As of the end of May, the manufacturer has agreed to recall the tank to its plant and evaluate for repairs. Tank removal is scheduled for early June 2013.

Deficiency Notice (DN) #7 was issued 5/16/13 for inadequate fabrication welding of Siemens’ stainless steel piping. As of the end of May, Train E piping was inspected and deficient spools were disassembled and removed from the gallery. Several pieces were taken to a local fabricator, Duhig, where the repair procedure is being developed.

DN #8 was issued 5/28/13 for enclosure damage to the new RO Transfer Pump Isolation Transformer.

In February 2013, certain restrictions on time constraints between adjacent concrete placements were eased providing schedule savings. Based on the May 2013 schedule update work in MF has 4 working days of float, indicating that pre-startup activities could begin in late January 2014.

RO Feed Pumps: Substitution of the RO Feed Pump supplier was agreed to by the Water District for Contractor’s convenience in April 2012, subject to review and approval of an equivalent submittal. The substitution RO Feed Pump submittal was received October 22, 2012. On December 4, 2012, the CM issued Bulletin No. 021 to revise the RO Feed Pump operating parameters due to new membrane performance projections as a result of the Water District-directed change to the RO membranes. In February 2013, several teleconferences were conducted to discuss the critical vibration frequencies occurring at low speeds when the membranes are new. On March 8, 2013 the RO Feed Pumps were approved for fabrication.

Based upon the May 2013 schedule update, RO Feed Pump installation will occur in late November 2013, with 12 days of float.

Energy Recovery Device: The configuration of the RO System Energy Recovery Device (ERD) has been subject to coordination teleconferences commencing in April 2012. Bulletin 29 was issued February 5, 2013, directing the Contractor to furnish an internal variable area nozzle to enhance the performance of the ERD in low pressure conditions. The ERD prototype was tested and approved in May 2013. The ERD installation has slipped to September 2013. Currently, there is no assertion of delay attributable to the ERD; however, it is being tracked as a potential issue.

SEFE Progress: The Contractor noted at the Preconstruction Conference and in the Baseline Construction Schedule narrative that the completing of SEFE area work in the time provided was challenging. The District turned the SEFE area over to the Contractor by Field Change Order 0041 on July 31, 2012, four months prior to the specified date.

The excavation plan for the pump station was not approved until January 29, 2013, and the SEFE tank foundations, which were initially approved in October 2012, are being redesigned by the Contractor to capture savings. This redesign was rejected in January 2013 for providing an inadequate safety factor. The Contractor continued to explore potential redesign to reduce the number of piles required, and on March 25, 2013 a teleconference was conducted at which the Design Engineer agreed that, subject to proper results, a re-test of the in-situ test

piles would justify reducing the factor of safety per applicable standards. The in-situ test piles were re-tested on April 15, 2013. The redesigned foundation was resubmitted May 17, 2013. A conference call regarding the calculations was conducted May 30, 2013 and supplemental calculations were submitted May 31, 2013.

The SEFE schedule concerns noted above have been compounded by the discovery of unforeseen contaminated soils. Pesticide concentrations in SEFE top soils were found in December 2012 by the earthwork subcontractor. Subsequent to investigation, the Water District’s Soils Removal Plan was sent to the Contractor on February 7, 2013. On March 25, 2013, the Contractor mobilized a hazardous materials subcontractor to commence grading operations is SEFE. The SEFE Tank Pads were completed in early April. However, further advancement of the SEFE tanks continues to be pending the Contractor’s redesign of the foundations.

The initial February 2013 schedule update inserted a delay activity for determination of the means and methods of handling the contaminated soils, with a projected end date of March 29, 2013. The delay was an estimate only and has not been justified by the Contractor. Only after the Contractor submits a time impact analysis and it has been approved, can time can by inserted into the schedule. The activity was removed from the schedule for the record.

Subsequent March, April and May updates reflected a nearly day-for-day slip due to SEFE inactivity. The April 2013 update has a forecast completion date of April 17, 2015, including recovery of three weeks due to a change being discussed to reduce the number of tank slab placements.

Operation of the Groundwater Replenishment System (GWRS) commenced on January 10, 2008. An update on operation of GWRS is provided below.

RECOMMENDATION

Informational

DISCUSSION

GWRS continues to produce water that meets all regulatory requirements. The OCSD new secondary treatment process has been operating efficiently in the nitrified/denitrified (NDN) mode of operation. As a result of OCSD process change the microfiltration (MF) and reverse osmosis (RO) processes continue to benefit with lower operating pressures and reduced solids loading compared when OCSD operated in the Carbonaceous Biochemical Oxygen Demand (CBOD) mode. With the completing of MF backwash storage project in June of 2012, where MF backwash water is stored in primary storage basins at OCSD, the GWRS has been able to process an addition 2.5 million gallons per day. Water stored in the primary basins is pump back into OCSD secondary process during the low diurnal flow period and is then treated by GWRS. Personnel from OCWD and OCSD are jointly operating these basins in addition to working together to inspect pumps and basins for solids buildup. The new Mira Loma spreading basin in Anaheim has been on line since July 26, 2012 along with Kraemer/ Miller basins. The ability to recharge GWRS water at Mira Loma has been outstanding. The basin has been able to recharge up to 50 mgd without any issues of the roughly 68 mgd produced by GWRS. Having this additional recharge capacity provides a significant amount of flexibility during winter storm event and being able to meet OCSD storm event requirements. For OCWD’s 2012/2013 fiscal year GWRS produced 72,674.40 acre feet which is 2,674.40 acre feet above our target production of 70,000 acre feet. The design

production for GWRS is 72,000 acre feet; however the target production of 70,000 acre feet was set because of expected downtime for the construction of the GWRS initial expansion project. However; staff achieved a 98.3% on line factor which allowed for the higher production and to also makeup for the lower diurnal flows at night. Another factor in being able to achieve a higher production is attributed to having Mira Loma spreading basin and not having to lower production due to spreading basins being full or down for cleaning. The GWRS effluent production for the months of April, May and June 2013 is shown in the following tables:
