WATER UPDATE
Water Quality
Financial and Operations Update
BOU Water Production
BOU production was at 58.45% of plant capacity for March. This is an average flow rate (24/7) of 5,260 gallons per minute (gpm). Plant production was limited because of cooler weather and one Vapor Phase Granulated Activated Carbon (VPGAC) filter train was down due to a broken carbon retention screen. This reduced the plant to half capacity for a total of 14 days through the end of the month. All LPGAC filters were in service. Six of the eight water wells were available for service. The pumps from the two wells out of service are being repaired and should be reinstalled by the early part of May.
Environmental Protection Agency (EPA)
A signed design contract between ECO, the BOU O&M contractor, and MEGTEC, the design and construction contractor for the VPGAC carbon retention screen replacement 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 May, 2007. EPA�s approval is then 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 18 weeks and will likely be completed by the end of summer. 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 the 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. 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. The parties met in January, February and March. Discussion continues with the Watermaster and the City of Los Angeles.
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 Maximum Contaminant Limits (MCL) 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. The promulgation of a Public Health Goal (PHG) [none currently in place] or a new MCL will come from the California Department of Health Services. Water Industry speculation places the anticipated PHG between 3-30 ppb. A PHG lower than 5 ppb, if adopted by the City Council, 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 thirteen, 4 kV feeder outages and six, 12kV feeder outages in March. These outages interrupted service to 5,317 customers for a total of 1,759 minutes. These were all due to high winds.
Despite the power outages in March, BWP�s overall reliability continues to be strong. As of March 31, 2007, the system-wide average is 0.2544 outages per year, compared to an industry average of 1.2 outages per year. The average service availability is 99.9948%, exceeding the City goal of 99.99%. The average outage length is 80.75 minutes, compared with the industry average of 80 minutes.
The following table shows the system-wide reliability statistics for Fiscal Year 2006-07 through March 31, 2007 as compared to the same time period for Fiscal Year 2005-06:

Renewable Energy Update
Utah Wind Development. During the month of March, negotiations were finalized with the developer of the wind project located in Utah. The next step is to develop power sales agreements between SCPPA and its members who are going to receive energy from the facility. LADWP is taking 92.5% of the project, and Burbank and Glendale are taking 5% and 2.5% respectively. No significant impediments are expected as we negotiate the power sales agreements between SCPPA and its members. The resource would provide about 2% of BWP�s energy requirements.
Pacific Northwest Wind Development. During the month of March, several negotiating sessions on a power sales agreement were held with the developer of a wind facility located in the Pacific Northwest. As part of the sales agreement, SCPPA is negotiating an option to purchase the facility when in comes on-line in late 2008. 20 MW from this resource would provide 4% of BWP�s energy requirements.
Imperial County Geothermal Development. Negotiations began for the energy associated with 9 MW from a geothermal facility located in the Imperial Valley in California. The in-service date of energy from the geothermal project is anticipated to be in late 2011, and would supply 6% of BWP�s energy requirements. Energy would be delivered to BWP via the proposed Greenpath Transmission Project when it is completed in 2010.
Greenpath Transmission Project. LADWP/LA, the project manager, reported that they are undertaking studies on the line configuration. The studies are looking at 1,200 MW transfer capability which should be complete in June of this year. However, the project may ultimately be changed to 1,600 MW.
The Bureau of Land Management (BLM) has been requested to provide their screening criteria for the preferred alignment of the line. The preferred alignment has the line moving up the eastern side of the San Gabriel range and then moving westward into Hesperia, north of the range. The BLM has asked L.A. to consider an alternate southern alignment, however L.A. has said that due to rampant land development that alignment is unfeasible. L.A. has an alternate northern alignment which juts further north than the preferred alignment and comes through an existing transmission corridor on its way down to Hesperia. That, however, may require an additional 15 miles of line and is not L.A.�s preferred alignment.
The BLM is the lead National Environmental Protection Act (NEPA) agency. L.A. is waiting on a Memorandum of Agreement and Cost Recovery agreement from the BLM. L.A. needs the local BLM and United States Forest Service (USFS) offices to participate in the process, however, their attitudes towards the project are somewhat ambivalent and cooperation has not yet been forthcoming. To get the project moving L.A. is considering attempting to get action at the regional or State and Federal levels where they believe they can garner support for the project, hoping to have the transmission corridor designated as a Federal utility corridor through the Department of Energy (DOE).
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 to connect the RTU CPU card directly using Ethernet instead of the device server that was originally installed is complete. The original RTU CPU could not be networked, but the new units were designed to be networked. In March, field crews implemented this for the remaining 11 RTUs.
Telecom
Engineering developed fiber optic service proposals for Ascent Media to connect the following facilities:
Engineering developed fiber optic service proposals for SohoNet to connect the following facilities:
Engineering developed the following additional fiber optic service proposals:
BWP field personnel completed a fiber optic job for the Public Works Traffic Department to re-splice/connect fiber on Hollywood Way to connect back to Public Works Yard.
Engineering personnel issued, and operations personnel completed, fiber optic jobs for Disney to connect the following locations:
Engineering personnel issued, and BWP field personnel completed, a fiber optic job for Craig Murray Production to connect 2717 W. Olive Ave. to 2401 W. Olive Ave.
BWP Facility Improvements
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.
Re-closing is especially important for BWP's overhead 12,470-volt circuits, which serve two to three times as many customers than the older, 4,160-volt feeders. Before this coming summer, BWP is going to add the re-closing feature to five, 12,470-volt distribution circuits (Keystone-6, Keystone-13, and Hollywood Way-4, 6, and 7) that are prone to transient faults from squirrels and wind-borne objects. Engineering work to add the re-closing feature to Keystone-6 and Keystone-13 was completed and issued for construction in February 2007. The remaining three circuits (Hollywood Way-4, 6 and 7) will be issued for construction in early May 2007.
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, Town-21, Winona -11 and Flower-3.
In September 2006, a job order was issued to re-conductor 124 spans of Victory-13 and Victory-14 feeders and primary conductors. This job is complete except for one primary lateral of Victory-13 at Evergreen St. north of Burbank Blvd. A job to re-conductor 135 spans of Victory-1 and Victory-7 feeders was issued in October, 2006. This is estimated to be complete by April 30, 2007. A job to re-conductor 28 spans of Victory-3 feeder will be completed in April as well. Currently, one crew is working on re-conductoring Town-21, and another crew will begin re-conductoring Town-4 in May 2007. BWP Engineering is working on re-conductoring Naomi-21 and Naomi-17 feeders.
Replacement of the underground cable for Victory-13, Victory-14, Town-19, Winona-11, Flower-3, Pacific-15 and Pacific-17 is complete. While re-conductoring the overhead portion of Victory-3, it was discovered that the underground cable in the riser pole was damaged and needs to be replaced. This will be replaced as soon as the cable order is received. 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.
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. Doble Engineering Company will review 30 critical transformers this fiscal year. The remaining transformers will be reviewed next fiscal year. Doble Engineering has started the preliminary work for this project. The final report is expected in July 2007.
BWP Administration Building - Phase III Interior Remodel
Icon West, Inc. has completed demolition work in the basement of the Administration Building, and has begun construction work. The project completion date for the entire building remodel is December 31, 2007.
BWP Service Center and Warehouse Project
BWP is negotiating a contract with McCormick Construction Company guided by the bridging documents by Kennard Design Group. If BWP and McCormick agree on a first lump sum price and terms and conditions, it would be scheduled for City Council approval by June 30, 2007.
Construction is scheduled to begin in January 2008 with an anticipated completion of July 2008. The next phase will demolish the existing Warehouse and the Line Section field offices, covered storage and parking. This area will be converted to employee vehicle parking. The next phase will also demolish the existing Water Maintenance Building along with the Guard House and install landscaping and additional employee parking. A new Security Office of approximately 600 square feet will be constructed on Lake Street at the intersection of Palm Ave. that will control ingress/egress to the entire BWP campus. A vehicle wash rack will also be added. Completion of the aforementioned phases is anticipated for January 2009. 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 equipment will be removed from the existing substation, the site will be scraped and the area converted into a courtyard.
Security Wall Construction
McClean & Schultz, Principal Architect, completed a structural review including engineering signatures/stamp on the drawings prepared by Bibb. Once the final construction documents are 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 January 2008, and be completed in March 2008.
Auxiliary Warehouse
BWP conducted a final job walk, generated a punch list and received the keys to the new auxiliary warehouse from Gonzales Construction. BWP personnel are in the process of performing the tenant improvements, electrical, lighting, and bathrooms in preparation for moving BTORA into the building. BTORA will be completely moved in May 14, 2007.
Communication Shop Relocation
After relocating BTORA to the float barn/former small fleet building, tenant improvement work will begin to provide a new home for the Communications Shop. Staff received BWP Board approval and contracted with McLean & Schultz, Principal Architect, on December 11, 2006. McLean & Schultz completed and submitted the final construction documents and technical specification package. Tenant improvement work on the Communications Shop is planned for completion in August 2007. Communications 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 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 or the spring of 2008, 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. Heat wave related work 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.
Replacement Burbank Station Project.
A contract was awarded to ABB Inc. in the amount of $17,247,260. A purchase order was issued on January 8, 2007. A kick-off meeting was held and the design work has started. All major pieces of equipment with a long lead time have been ordered. Potholing work was started and completed in February 2007. Construction of the duct system on the BWP campus has started and will be completed by June 30, 2007. Duct work outside the BWP campus will start during the summer of 2007, and will be completed by December 31, 2007. The foundation and equipment pad construction will start in June 2007, and will continue until November of 2007. Major equipment delivery is estimated between November 2007, and January 2008. The Station will be partially energized by June 2008. Most of the 34,500- volt network will be transferred to the new station by June 30, 2009.
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 involved 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. This work was completed in March 2007. It 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 work is in progress. On the Catalina site, 2 padmount switches and 4 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. 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. On January 26, 2007, Krismar Construction Company, on behalf of M. David Paul, paid $1.2 million as a reimbursement for the system improvement for Phase-1, and paid $300,000 as a first installment of the direct cost of service. Krismar Construction is scheduled to pay another installment of $300,000 in April 2007 and will pay the remaining $455,000 by June 30, 2007. The official name of this project is � The Pointe �.
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. The City Council approved this work at its meeting of March 13, 2007.
12,470-Volt Distribution System
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, all but one customer station as been 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 2006, to reconductor 37 spans of feeder conductors in preparation of the 12 kV conversions. Reconductoring of the overhead portion of the A-8 and A-96 feeders are complete.
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.
Customer Transformer Stations
Since July, Engineering has responded to 101 written 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.
Two new pad-mount transformers were energized in March.
Undergrounding
The City Council approved the establishment of the first Underground Utility District within the City of Burbank for Olive Ave. between Victory on the I-5 overpass. Construction started in early March.
BWP Engineering completed 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. Caltrans awarded the contract for the SR-134 Project and requested a Utility Agreement be approved. The City Council approved the agreement on March 13, 2007, and extended the contract with Bock Company for the duct work. Bock Company will start work at Riverside Dr. between Olive Ave. and Hollywood Way on April 16, and will continue to support BWP as needed to meet the schedule of the Caltrans Project.
Streetlighting System
Fiscal year-to-date, 69 streetlight standards and 17 lights on power poles have been installed. Out of these, 52 streetlight standards were installed as a part of the South San Fernando Blvd. Street Improvement Project, and three streetlight standards were installed as a part of the Carmax Project. One series circuit was converted to low voltage in February, 2007. Two more streetlight standard installations were issued to Operations in March. Engineering is working on a BWP Streetlighting Master Plan and new street/traffic improvement projects with Public Works and the Traffic Signal Division (several Burbank Blvd. intersections, Main/Victory, Third/Verdugo, Hollywood Way/Winona, and Hollywood Way/Thornton). Construction continues on Olive Ave. and Empire Ave. Undergrounding of the streetlight system on Olive Ave. is almost complete.
