WATER UPDATE
Water Quality
Financial and Operations Update
Fiscal Year 2006-07 Water Fund Financial Reserve balances as of December 31, 2006 are summarized in the following table:
BOU Water Production
BOU production was at 47.48% of plant capacity for December. This is an average flow rate (24/7) of 4,273 gallons per minute (gpm). Lower water production was due to a number of the Liquid Phase Granulated Activated Carbon (LPGAC) filters being down for carbon change out. Carbon change out was completed in 4 of the 12 LPGAC filters. Turn around by the carbon vendor was slowed due to the holidays. The lower production was mitigated by a reduced demand due to cooler weather. All of the Vapor Phase Granulated Activated Carbon (VPGAC) filters were available for service. All water wells were available for service and the water table is still higher than the last few years. Higher water levels may be attributable to a significant reduction in groundwater pumping by the City of Los Angeles through much of this year. Los Angeles has begun to increase their pumping and it�s not clear at this time if the higher production rates from our wells will be able to be sustained for an indefinite period. The BOU is scheduled for a two week shutdown in January due a lack of MWD water for blending. MWD will be performing planned maintenance and will not be able to provide water to the B-5 blending connection. Burbank will purchase treated water from MWD during the shutdown via Burbank�s other MWD connections.
Environmental Protection Agency (EPA)
The EPA has granted conceptual approval of the design for the reconfigured VPGAC filter screens and issued the VPGAC discharge requirements in mid-February 2006. A signed design contract between ECO, the BOU O&M contractor, and MEGTEC, the design and construction contractor for the VPGAC project was in place December 15, 2006. The final design package will include an updated construction cost estimate for the project and should be available for EPA review by the end of January. The EPA�s approval is the controlling feature in proceeding with the project. We are working to get an expedited review and approval from EPA. Construction is projected to take three months and will likely take place during the winter. The Treatment Plant will experience reduced operating capacity during project construction. Consequently, there will be an increased need for purchased water from the Metropolitan Water District (MWD) during construction. These additional water purchases from MWD will significantly impact WCAC expenses and may result in use of a significant portion of the WCAC balance.
San Fernando Basin Groundwater Credits
Burbank, Glendale and Los Angeles are discussing the issue of an over statement of Import Return Groundwater Credits in the San Fernando Basin. The discussion is centered on the calculation of the credits within the context of the 1979 Judgment that adjudicated the basin and is under the administration of the Upper Los Angeles River Area Watermaster. The Cities met again with the Watermaster in November 2006. Burbank and Glendale are in disagreement with the Watermaster as to the proper application of the terms of the Judgment to resolve the imbalance of ground water credits. Discussion continues with the Watermaster and the City of Los Angeles. The parties will meet again in January 2007.
Chromium Contamination in the Groundwater
Drinking water in Burbank does not exceed 5 parts per billion (ppb) chromium by direction of the City Council. This is achieved by blending the BOU produced water with MWD water to obtain the 5 ppb concentration. Current Federal and State limits are 100 ppb and 50 ppb, respectively. Work has been underway for the last four years to develop a new limit for chromium. Work is being done by the National Toxicology Program (NTP) within the EPA. Results are expected within the year. Any limit above 5 ppb will be positive for Burbank. A new limit lower than 5 ppb would limit Burbank�s current operations and increase reliance on imported MWD water, or require additional treatment for removal of Chromium. Either alternative would significantly increase Burbank�s water costs.

ELECTRIC UPDATE
Electric Reliability
There were two, 4 kV feeder outages in December. These outages interrupted service to 1,357 customers for a total of 191 minutes.
Despite the power outage in December, BWP�s overall reliability continues to be strong. As of December 31, 2006, the system-wide average is 0.1611 outages per year, compared to an industry average of 1.2 outages per year. As of December 31, 2006, the average service availability is 99.9955%, exceeding the City goal of 99.99%. The average outage length is 73.48 minutes, compared with the industry average of 80 minutes.
The following table shows the system-wide reliability statistics for Fiscal Year 2006-07 through December 31, 2006 as compared to the same time period for Fiscal Year 2005-06:

Renewable Energy Procurement Update for December 2006
During the month of December, negotiations continued on the wind project located in Utah. It continues to take considerable time to develop contract language that will enable SCPPA participants to prepay for the energy from the project (to get a discounted price), and buy the project from the developer at some time in the future and not run afoul of IRS regulations. The participants remain optimistic that a definitive agreement can be worked out in the next several months based on an arrangement where we would prepay for a specified amount of energy each year with the right to purchase the project outright from the developer after 10 years.
Work also continued on the potential solar development. The participants remain concerned about the potential cost of the project and are continuing to work with the developer on ways to lower the cost. At this point the cost of the project remains high and the developer is unwilling to grant us the right to acquire the project from them. In view of this, it seems likely that SCPPA will not be proceeding with the project but no formal decision to that effect has been made.
The work plan is to continue working with the Utah developer on the wind project, the solar developer, and commence negotiations with a wind developer for a project located in the Pacific Northwest. Work also continues by URS on the feasibility study of green-waste to energy facilities in the LA Basin with an expected completion date later this spring.
SCADA/EMS
BWP engineering staff continues to work with Siemens New Energy to implement the New Energy Scheduling software that is being used for Magnolia.
Engineering work was started to connect the RTU CPU card directly using Ethernet instead of the device server that was originally installed. The original RTU CPU could not be networked but the new units were designed to be networked.
Telecom
Engineering personnel developed a fiber optic service proposal for Disney to connect 2323 Brighton St. to the following locations: the Team Disney Building at 500 S. Buena Vista St., the Frank G. Wells Building at 500 S. Buena Vista St., and the Disney ABC Building at 2300 Riverside Drive.
BWP Facility Improvements
BWP Administration Building - Phase III Interior Remodel
Thirty-three contractors attended the mandatory pre-bid job walk conducted on September 13, 2006. The bid opening was held on October 3, 2006. Five contractors submitted bids ranging from $2,765,500 to $2,980,700. Staff received approval at the November 2, 2006, BWP Board meeting to award the contract to Icon West, Inc., who submitted the second lowest bid of $2,858,730. A pre-construction meeting was held on Friday, December 8, 2006. The construction fence will go up on Saturday, January 6, 2007. The contractor�s trailer will be on-site January 8, 2007, and work will begin in the basement of the Administration Building. The project completion date for the entire building remodel is December 31, 2007. An updated project schedule is displayed throughout the Administration Building.
BWP Service Center and Warehouse Project
All requested documents (MPP Service and Control Building as-builds, Electric Shop Building as-builds, sub-structure drawings, topographical site survey, etc.) were provided to the Kennard Design Group (KDG) who is the bridging architect developing the design development and detailed specifications. The resulting deliverable will accompany the RFP for a design/build team. A geotechnical report was completed by Arroyo Geotechnical and sent to KDG. BWP developed a draft Statement of Qualifications (SOQ) which was reviewed and approved by Purchasing and the City Attorney. This SOQ was advertised December 6 and December 9, 2006, and will be used to select the design/build team. The City Council approved the design/build concept via Resolution No. 27,311 on September 19, 2006. KDG is awaiting the approval of both the space allocation plan and conceptual design from BWP for the Service Center. Construction is scheduled to begin in June 2007, with an anticipated completion date of July 1, 2008. The next phase will demolish the existing 13,000 square foot Warehouse and the Line Section field offices, lockers and covered storage and parking. This area will be converted to employee vehicle parking. The next phase will demolish the existing 5,000 square foot, two-level Water Maintenance Building along with the Guard House, and will install extensive landscaping and additional employee parking. An approximately 600 square foot Security Office will be constructed on Lake Street at the intersection of Palm Ave. which will control ingress/egress to the entire BWP yard. A new vehicle wash rack will also be added. The final phase of the project constructs a replacement Burbank Substation with a state-of-the-art GIS substation which will be built at the southwest corner of the campus on a footprint one-third the size of the existing Burbank Substation. All of the equipment will be removed from the existing substation, the site will be scraped, and the area will be converted into a staff courtyard/park.
Security Wall Construction
Staff received BWP Board approval for a PSA with McLean & Schultz, Principal Architect for structural review and engineering signatures/stamp on the drawings prepared by Bibb. Once completed, a bid package will be assembled and submitted to Purchasing for the competitive bid process to hire a contractor. Work is anticipated to begin in March 2007, and will be completed by May 2007.
Auxiliary Warehouse
The former float shed was disassembled and removed. The remaining concrete support piers and foundations were demolished by the contractor. Canvas was rolled up and stored for BTORA use. Cargo containers were relocated. New welding circuits and electrical outlets were established. Soil borings were completed for a geotechnical analysis and report. BWP Board approved awarding a contract to Gonzales Construction for assembling the auxiliary warehouse. Purchasing sent the award letter to Gonzales Construction on June 9, 2006. Gonzales submitted all required documents, including bonding and insurance, back to Purchasing on June 26, 2006. Following a review by the City Attorney�s Office and Risk Management, and approval signatures from BWP, a purchase order was issued on July 7, 2006. Butler Buildings completed the design and BWP reviewed and approved the design. The building was fabricated and delivered on-site October 24, 2006. Site preparation work is complete, the concrete slab will be poured the week of January 8, 2007, and construction will follow. Building erection will take four to six-weeks and the fire sprinklers another week. BWP personnel will perform the tenant improvements including electrical, lighting, bathrooms and kitchen. All construction work is now scheduled for completion at the end of February 2007. BTORA has an anticipated move-in date of March 2007.
Communication Shop Relocation
Staff received BWP Board approval for a PSA with McLean & Schultz, Principal Architect. The 90% completed space allocation and design drawings were reviewed and approved by BWP staff. McLean & Schultz received formal approval to proceed with finalizing the construction document and technical specification package for the competitive bid process. Tenant improvement work on the Communication Shop is planned for completion mid-June 2007. Communication Shop staff can then be relocated, allowing for the construction of the Replacement Service Center/Warehouse.
Electrical Distribution
Construct a New Olive-Valley #2 Line
The consultant, ORSA, completed the design for pads and underground power conduits for the extension of the ring bus at the Valley Switching Station. Bock Company completed the duct work inside the substation and in the direction of Ralph Foy Park. They also completed all duct work required on Victory Blvd. up to Fairview, except for the small underground conduits to the new riser pole. The final design for ground grid and equipment pads was completed and issued for construction. Construction work for the control and communication conduits is in progress. Pouring the equipment pads, and related civil work, is also in progress and expected to be completed by the end of January 2007. Steel fabrication is underway and will be galvanized before being delivered on-site in January 2007 for installation. Construction of the overhead portion of this line along Victory Blvd. from the Costco area to Victory Blvd. and Fairview St. will include the replacement of 30 poles, upgrading 3,000 circuit feet of overhead conductor, adding new polymer insulators and changing the insulators from porcelain to polymer. This work may have to be delayed from Spring until the Fall of 2007 due to the need to upgrade the capacity of the 4,160 volt overhead lines identified as a result of the heat wave in July 2006. This needs to be completed before the summer of 2007 in order to prevent circuit overloads and potential power outages. Olive-Valley #2 needs to be completed before June 2008.
34,500-Volt Sub-transmission System
Field crews upgraded the underground cable, and upgraded the relay protection between the Olive Switching Station and the Burbank Substation to increase the capacity of the Burbank-Olive #2 line. The remaining underground cable work including termination, cable support, cable enclosure, and protection work was started on June 2, 2006 and completed by June 9, 2006. The line was energized by June 16, 2006 along with the A-5 transformer bank at the Olive Switching Station. ABB finished the remaining small bus upgrade related to the A-4 transformer bank at the Olive Switching Station as well as all related drawing as-builds. A Notice of Completion for ABB�s contract in the amount of $3,911,988 was recorded at the L.A. County Offices on August 14, 2006. All work related to undergrounding the 34,500-volt cable is completed until construction starts on the Replacement Burbank Station Project. Ten percent retention of the ABB contract will be released in March of 2007.
Replacement Burbank Station Project.
On June 27, 2006 the City Council approved the Request for Proposal (RFP) for Replacement Burbank Station under RFP No. 1216. After completing all technical specifications, preliminary drawings and terms and conditions, the RFP went out on August 9, 2006. A pre-bid conference was held on August 30, 2006. The last date to submit proposals was October 10, 2006. Evaluation of the proposals was done between October 11, 2006 and November 17, 2006. The oral presentations were scheduled for November 14, 2006. The evaluation was completed and the award of contract was approved by the City Council at its meeting on December 12, 2006. The contract was awarded to ABB Inc in the amount of $17,247,260. A Purchase Order was issued on January 8, 2007. The construction will start in May 2007, and the completion date is June 30, 2009. 34,500-Volt Distribution System
At the Winona Distributing Station, field crews upgraded relay and control switches for the Winona Industrial Circuit in preparation for reconfiguring the line.
Compliance with NBC Master Plan - Planned Development 96-1
BWP staff provided comments to the Community Development Department regarding the compliance with Planned Development 96-1, expanding the parking under LADWP�s 230 kV high voltage lines near NBC, and the method of service for M. David Paul Development on the Catalina property. Providing electric service for this development involves an extension of the 34,500-volt line (ducts and cable) from Willow St. along Fredrick St. to Alameda Ave., and along Alameda Ave. from Fredrick St. to Naomi St. The related duct work has been completed. The related cable work is expected to be completed by March 15, 2007. The work also involves adding a new 34,500-volt line position at Naomi Station, as well as a small amount of work at Capon Switching Station. This too is in progress at this time. On the Catalina site, two padmount switches and four padmount transformers will be required to transform power to utilization voltage for the parking structure and both office buildings. Under the current BWP Rules and Regulations, M. David Paul will pay 100 percent of the cost of the work directly related to its service as aid-in-construction charges, and will also reimburse BWP its prorated share of system improvements completed since July 2001 in the amount of $30 million. The M. David Paul service will not have a negative fiscal impact on BWP customers nor impact reliability of service to existing customers. Staff energized temporary construction power for this project after CDD-Planning�s approval.
Reliability of the Golden State Distributing Station
In most of BWP�s substations, BWP can restore power by making use of a direct connection to the station transfer bus, or by transferring load to other stations. These options are not available at the Golden State substation, which had experienced switchgear problems in 2005. Working with its engineering consultant, Power Engineers Inc., BWP has found a way to make a direct connection between Golden State�s transfer bus and the power transformers, while also adding a substation capacitor bank. Staff will be reviewing this solution with the BWP General Manager and determining the next steps needed to implement it.
12,470-Volt Distribution System
The engineering and construction work to rebuild the 4 kV feeder areas A-8, A-96, and A-97 is in progress. This will ultimately convert the area to 12 kV service from the new Hollywood Way Station (HW-4 and HW-6). As a part of this effort, customer stations will be rebuilt to 12 kV. Alameda Feeders A-8, A-96 and A-97 will be physically removed from the Alameda Distributing Station after the conversion is complete. This goes along with BWP�s plan to transfer load to a new state-of-the-art substation like the Hollywood Way Station, and will eliminate the 50 year old plus substations like Alameda. This work is also required as a part of the Caltrans SR-134 project. Two work orders were issued in September to reconductor 37 spans of feeder conductors in preparation of the 12 kV conversions. Reconductoring of the overhead portion of the A-8 feeder was completed in November and the overhead portion of the A-96 feeder was completed in December. Progress continues on rebuilding deteriorated pole lines and single pole replacements.
The Keystone and Golden State Distributing Stations were included in the under-frequency load shedding scheme to provide better capability to automatically shed load and balance load with generation. This addition will help to stabilize and restore the system much faster in the event of the loss of a big generation source such as the tie with LADWP or MPP.
Implement Automatic Reclosing of Distribution Circuits
Often, an object causes a short circuit on a power line for only an instant (technical term: transient fault), and does not damage the line. For example, a branch may fall between two conductors, touching them only briefly; or a kite tail may instantly vaporize as soon as it touches two conductors. The utility industry has responded to these situations by using reclosers, which closes a line back in very soon after it has been short circuited. If the cause of the short circuit is no longer present, the line stays in service; if the cause is still present, the line relays out soon enough to avoid damage to the line.
Reclosing is especially important for BWP's overhead 12,470-volt circuits, which serve two to three times more customers than the older, 4,000-volt feeders. Before this summer, BWP is going to add the reclosing feature to five, 12,470-volt distribution circuits (Keystone-6, Keystone-13, Hollywood Way-4, 6, and 7), that are prone to transient faults from squirrels and wind-borne objects.
4,160-Volt Distribution System- Impacts of heat wave and follow up action plan
After the July 2006 heat wave, the Energy Control Center (ECC) initially reported 32 distribution circuits showing overloads. BWP Electrical Engineering carefully reviewed the loading of those circuits and identified 11 distribution circuits where corrective measures are required to prevent future outages. It was determined there is a need to upgrade and replace underground cable with a larger size cable, and to replace overhead conductors with a larger size that will increase capacity in neighborhoods where the circuit loads went beyond the emergency rating of the conductors. This may have possibly shortened the life of the conductors. In order to maintain reliability of service and proper voltage, these upgrades must be completed before next summer. Those circuits include Victory-13, Victory-14, Victory-1, Victory-3, Victory-7, Town-19, Town-4, Winona -11 and Flower-3.
In September, a job order was issued to reconductor 124 spans of Victory-13 and Victory-14 feeders and primary conductors. This job is currently under construction. A job order to reconductor 135 spans of Victory-1 and Victory-7 feeders was issued in October. The job order to reconductor Victory-3 was engineered in November, and the job order to reconductor 46 spans of Town-4 was engineered in December. The reconductoring of Town-21 will be issued in the winter of 2007. Replacement of underground cable for Victory-13 and Victory-14 was completed in October 2006. Replacement of the underground cable for Town-19 was completed in November. The cable replacement for Winona-11 and Flower-3 is expected to be completed by December 31, 2006. Although necessary, this work will have an impact on the budget and resources. It will have a financial impact of $1.7 million ($1.1 million for labor/overhead and $600,000 for cable and other materials). It will also add approximately 10,800 man-hours of field crew work, 10,000 of which will be the overhead line construction crews. These additional man-hours have a major impact on other planned projects such as pole line rebuilds, 12 kV conversion jobs, and other customer service related work. Staff is reviewing options for the best possible solution. A shortage of resources is not a unique problem for BWP, and the neighboring utilities have the same challenge.
Although our substations are well maintained and loading has been light in the past, some substation loads exceeded the N-1 contingency rating of substation power transformers during the heat wave. Most of our substations are 50 plus years old, with some as old as 66 years. The age of the transformers is a concern to staff, specifically if we lose one of the substation power transformers during the summer. If that were to happen the remaining one or two would have to carry the load and would become overloaded. Loss of a station power transformer may have a more serious impact on customer reliability than losing one distribution circuit. It could have a cascading outage impact and cause the whole substation to go down. Staff has completed an analysis of the loading on the substation power transformers and has considered two consulting firms (ABB Inc. and Doble Engineering Company) to further study the Condition Assessment and Potential Risk of Failure in order to forecast the remaining life of the power transformers. BWP Staff has determined that although this study may not predict the remaining life and risk of failure of the power transformers with 100 percent accuracy, it will assist in preventing sudden failures as well as the potential for cascading power outages. Because the cost of this study is more than $75,000 and was not budgeted this fiscal year, it will need City Council approval. BWP Staff is preparing a recommendation to Council to be considered for award on January 30, 2007.
Secondary Voltage System and Electric Metering
Remote read meters installed in November:
Engineering is working with AT&T on providing services to 127 fiber optic nodes for Project Lightspeed. By the end of December, 113 excavation permits had been processed by Engineering for this project. Customer Transformer Stations
Since July, Engineering has responded to 47 requests for review and comments from the Community Development Dept.
New business, and a strong residential real estate market, has created a demand for new customer stations.
Five new pad-mount transformers were energized in November. BWP Engineering continues working with the Burbank-Glendale-Pasadena Airport and its consultant, KSG, on improving the reliability and back-up of its existing service for the main terminal building located at Empire Ave. The airport will pay all BWP aid-in-construction charges currently applicable under the Rules and Regulations.
In November, the customer station at the shopping center on Pass Ave. was rebuilt to 12 kV.
Undergrounding
BWP has worked with the City Attorney�s Office, the Public Works Dept., and the Community Development Dept. in forming Underground Utility District 1 (UUD1) to underground all overhead lines (power and communications) along Olive Ave. from the I-5 Bridge to Victory Blvd., and along Lake St. from Olive Ave. to Magnolia Blvd. BWP has been successfully working with SBC, Charter Communications, and other affected communication companies as well as the affected customers. On May 30, 2006, the City Council passed a Resolution of Intention. After a public hearing on June 20, 2006, the City Council voted and approved to establish the first Underground Utility District within the City of Burbank. BWP Engineering proceeded with the final design of the conduit system and went out to solicit bids on July 18, 2006. The pre-bid meeting was held on August 9, 2006. Nine companies attended the pre-bid meeting but only two submitted bids on the day of the bid opening, September 5, 2006. Both bids were greater than the engineer�s estimate. Most of the major contractors such as Bock Co., W.A. Rasic, Irish Construction and Doty Bros. did not submit bids. On September 15, 2006, BWP requested the City Manager reject both bids with the intention to solicit new bids. The City Manager accepted our request and rejected both bids. The submitted bids have been re-analyzed and discussed with the Public Works Dept. A few changes have been made including allowing more time for completion, working hours, and the amount of paving required. Three major contracting companies, Pouk and Steinle Inc., PAR Electrical, and Contra Costa Electric, have shown an interest. The new bids are out and the pre-bid meeting was held on October 31, 2006. Seventeen companies attended the pre-bid meeting. The last date to submit bids is December 5, 2006. In spite of BWP�s best efforts to attract more bidders, only one bid from J Fletcher Creamer and Son was received at the bid opening. Fortunately, the bid amount is close to the engineer�s estimate and within the overall budget of the project. BWP is scheduled to present this to Council on January 23, 2007.
BWP Engineering is working on two projects related to Caltrans. One project involves the Alameda, Hollywood Way and Pass Ave. bridge widening on the SR-134, and a new on-ramp at Hollywood Way. The second project involves the I-5 freeway, Empire Exchange, and San Fernando Realignment. Staff is working with consultants and Caltrans on conceptual design work that requires the relocation of existing underground and overhead facilities as well as a cost estimate.
BWP Engineering is working with the consulting firm of Black and Veatch to place all projects on MS Projects. This is tentatively scheduled to be completed during Fiscal Year 2006/07, and will help with the assessment of resources and improve the planning process.
In anticipation of the new work order and asset management system, BWP has assigned engineering and field personnel to work with Black and Veatch on construction standards, bills of material, compatible units, and developing tools for quicker and better cost estimates for in-house pole line rebuilds and 12 kV conversion jobs. That concept will be extended to other areas of construction such as underground, customer station installation, streetlight, and substation work.
Streetlighting System
In response to customer requests in December, Engineering issued work orders to install 1 streetlight standard and 3 lights on power poles. Since July, 6 streetlight standards and 12 lights have been installed on power poles. A work order to replace rusted octaflute standards on Victory Blvd. was engineered in December. Engineering is working on a BWP Streetlighting Master Plan and new street/traffic improvement projects with Public Works and the Traffic Signal Division (Burbank Blvd., Main/Victory, Third/Verdugo). Construction continues on Olive Ave., South San Fernando Blvd., and Empire Ave.
Parks, Recreation and Community Services and Public Works were issued portable radios in December and moved onto the new system. The entire city is now on the new system.
A bid was awarded for the new Police mobile data terminal (MDT).
Phones and Miscellaneous
All phone systems are working.
The ongoing voicemail problem was addressed with AT&T. AT&T has ordered spare parts and will keep them on site at the central office. Legislative Update:
