WATER UPDATE
Water Quality
Financial and Operations Update
BOU Water Production
Burbank Operable Unit (BOU) production was at 85.36% of plant capacity for May. This is an average flow rate (24/7) of 7,682 gallons per minute (gpm). Plant production was only constrained by reservoir capacity as the system filled. Six of the eight water wells were available for service with five wells providing the required flow. The pumps and motors from the two wells out of service are being repaired or replaced. New power conductors, or wire, are being pulled through existing conduits for both wells. The pumps should be ready for service by the end of June.
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. Plans were submitted to BWP and were returned to MEGTEC for revision and correction. A revised set of plans should be ready for EPA review by early July. EPA�s approval is then the controlling feature in proceeding with this project. We are working to get an expedited review and approval from the EPA. EPA also requested a full scale test of utilizing virgin carbon in the VPGAC filter vessels and deleting on-site carbon regeneration. A test is being set up but will have to run a minimum of 60 days. Lockheed Martin has agreed they bear the cost of all of this work. In the meantime, the MEGTEC design will be completed so that a decision on the project alternate can be made as soon as possible. This testing will delay the start of the project which probably can�t start now until October. Construction is projected to take 18 weeks and will likely be completed by the end of February 2008. The Treatment Plant will experience reduced operating capacity during project construction. There will be an increased need for purchased water from the Metropolitan Water District (MWD) during construction however, the timing of the construction will now reduce the water volumes that will be purchased. 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. 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. Los Angeles, Glendale and Burbank have continued to meet since January, and have tentatively reached an agreement with each other and the Watermaster. Work on a final document for a 10-year program of interim replenishment and enhanced water storage in the San Fernando Basin is being developed for presentation to the Court.
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 of the study were released May 16, 2007. The study concluded that Chromium VI is a carcinogen when ingested. The study used high concentrations of chromium, the lowest being 5,000 ppb. The promulgation of a Public Health Goal (PHG) [none currently in place] and a new MCL are the next steps and 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
Safety
We had one lost time incident in the line section involving a Line Mechanic Apprentice, who has recently been returned to light duty.
Electric Reliability
There were four, 4 kV feeder outages, one, 12 kV feeder outage, and two customer station outages in May. These outages interrupted service to 1,001 customers for a total of 339 minutes.
Despite the power outages in May, BWP�s overall reliability continues to be strong. As of May 31, 2007, the system-wide average is 0.3059 outages per year, compared to an industry average of 1.2 outages per year. The average service availability is 99.9955%, exceeding the City goal of 99.99%. The average outage length is 70.62 minutes, compared with the industry average of 80 minutes.
The following table shows the system-wide reliability statistics for Fiscal Year 2006-07 through May 31, 2007, as compared to the same time period for Fiscal Year 2005-06:

Renewable Energy Update
Utah Wind Development. Preparation of the power sales agreements between SCPPA and its members that will receive energy from the facility was very nearly finalized. It is currently expected that this agreement between SCPPA and the off-takers Burbank, Glendale, and LADWP, will be completed in June 2007. Burbank has a ten (10) MW interest in this resource.
Pacific Northwest Wind Development. During the month of May, negotiations continued with the developer of a wind facility located in the Pacific Northwest. Word got out from the seller�s negotiator that their new corporate owner�s business model precluded the sale of the facility to SCPPA. Due to a demand in the region for renewable energy, and other states adopting higher or new renewable portfolio standards, there has been increased demand for renewable energy. They are now only interested in negotiating a power sales agreement. How this development might affect negotiations, and whether SCPPA will proceed with a power purchase agreement isn�t clear. Burbank has a twenty (20) MW interest in this resource.
Imperial County Geothermal Development. SCPPA continues with preliminary planning work on a geothermal facility in Imperial County. The in-service date is currently anticipated to be in late 2011, or early 2012. Nine (9) MW in the initial phase would supply 6% of BWP energy requirements. Energy would be delivered to BWP via the proposed Greenpath Transmission Project for which an update can be found below.
Greenpath Transmission Project. Planning work continues on this project by LADWP/LA, the project manager, with a currently anticipated in-service date of late 2010, or early 2011. Current plans are for 1200 MW transfer capability. However, ultimately this may be increased to 1600 MW.
Work continues on getting the project licensed. Recently there has been improved cooperation from the Bureau of Land Management and the U.S. Forest Service in coordinating the licensing effort. As well, LADWP, the project manager, continues to work directly with environmental groups and the public, hosting community meetings to address concerns regarding potential project impacts.
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. Calculations were added to the master SCADA station to determine feeder imbalance between phases. Alarms were set to alert the dispatchers when imbalances were getting near the trip point of the feeder so that short-term remedial action can prevent outages due to feeder imbalances. This action was triggered by the Burbank B-24 outage on May 7th due to imbalances in the feeder phases.
Telecom
Engineering developed a fiber optic service proposal for Warner Brothers to connect the Warner Lot through the Warner Station Power House to Ascent Media at 2130 Hollywood Way.
Engineering developed an additional fiber optic service proposal for Disney to connect 500 S. Buena Vista to Disney at 1201 S. Flower in Glendale.
Engineering developed a fiber optic service proposal for Ascent Media to connect the following facilities:
BWP Field personnel completed a fiber optic job for Warner Brothers to connect the Warner Ranch (CW) to The Switch at 3400 Motor Ave. in Culver City.
Engineering released four (4) fiber optic service jobs related to the Olive Ave. underground project. Jobs are to re-route fiber links affected by the project:
BWP Field personnel completed fiber optic jobs for Disney, connecting the following locations:
BWP Facility Improvements
Implement Automatic Reclosing of Distribution Circuits
Often, an object causes a short circuit on an overhead 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 six, mostly-overhead 12,470-volt (12 kV) circuits, which serve two to three times as many customers than the older, 4,160-volt feeders. BWP will add the re-closing feature to two, 12 kV distribution circuits (Keystone-6, Keystone-13) before August 31, 2007 and to four circuits (Hollywood Way-4, 5, 6, and 7) before January 2008. BWP is currently modifying its procedures to assure that reclosing does not endanger electrical workers who may be working on these lines and will meet and share the new procedures with the International Brotherhood of Electrical Workers (IBEW) before implementing.
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 carefully reviewed the loading of those circuits and identified 12 distribution circuits that needed reconductoring with larger lines that can safely carry heavier currents:
The re-conductoring work was not a part of the Fiscal Year 2006/07 CIP Budget as the need for it did not become apparent until after the July 2006 heat wave. When completed, this work will have cost $1.7 million ($1.1 million for labor/overhead and $600,000 for conductor, cable and other materials). The impact on the Fiscal Year 2006/07 CIP Budget will be minor due to delays in three budgeted capital projects: Olive-Valley No. 2, Replacement Burbank Station, and Olive Avenue Underground Utility District 1.
Substation power transformers serve a neighborhood, or a very large customer like a major studio. Even during the 2006 heat wave, all substation transformers were loaded well under their rated capacity because every substation has two or three substation transformers. If one of the substation transformers should fail during a heat wave, the remaining transformer(s) will be able to handle the other transformer�s load as well as its own with minimal overload. Nevertheless, BWP believes it is prudent to assess the remaining useful life of its substation transformers so that it can replace them well in advance of a crisis situation. The average age of those station transformers is 45 years, with some as old as 66 years.
Doble Engineering Company is assessing 30 critical transformers, and are currently making visual inspections and analyzing available records. Analysis and review of maintenance records and past loading history of station transformers will continue through June, with the final report in July. (Other critical transformers will be reviewed next fiscal year.)
BWP Administration Building - Phase III Interior Remodel
Icon West, Inc. completed construction work in the basement-level of the Administration Building. Construction work has begun on the first floor (east wing), second floor (east and west wing) and third floor. The project completion date for the entire building remodel is January 2008.
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 St. 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.
Communication Shop Relocation
Work has begun to provide a new home for the Communication Shop. McLean & Schultz completed and submitted the final construction documents and technical specification package. Tenant improvement work on the Communication Shop will begin June 2007, and is planned for completion in December 2007. Communication Shop staff can then be relocated, allowing for the construction of the Replacement Service Center/Warehouse in January 2008.
Electrical Distribution
Construct a New Olive-Valley #2 Line
Olive Station Portion: Most of the work such as equipment pads and setting breakers and disconnects is done except for structures and devices to terminate new underground cable from the newly installed duct system which is underway along Olive Ave. Engineering for relays and panel work is currently underway and will be issued to the field crews.
Olive Underground Portion: Duct and maintenance vault construction is underway along Olive Ave. and completed from the Olive and Lake intersection to the Olive and Victory intersection, and north and south of the intersection to the new riser pole. Duct work remains in the block between Lake St. and the west edge of the Olive Ave. Bridge. Work will be completed by July 31, including the final street paving.
North-South Victory Portion: Not yet begun. May not require replacement of poles, just reconductoring. This project was delayed to allocate field resources to complete the re-conductoring jobs originated as a result of the July 2006 heat wave.
Five Points Underground Portion: Ducts and maintenance vaults installed at time of Five Points project.
East-West Victory Portion: 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 has been delayed to Fall 2007 in order to utilize the field crews on re-conductoring jobs.
Valley Station Portion: 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 and to the new riser pole. The final design for ground grid and equipment pads was completed and issued for construction. All equipment pads, control/communication conduit work along with the ground grid work in the extended ring-bus area is completed. All breakers and disconnect switches are set on the pads and structures. Most of the bus work is finished and the remaining bus work is to be completed by June 30, 2007. The remaining ground-grid, control/communication wiring work, and relay panel work is estimated to be completed by January 2008.
Replacement Burbank Station Project.
A contract was awarded to ABB Inc. in the amount of $17,247,260. All major pieces of equipment with a long lead time have been ordered. Construction of the duct system on the BWP campus started on April 23, 2007 and will be completed by July 16, 2007. Duct work outside the BWP campus along Lake St. from the security gate to Magnolia Blvd., along Magnolia Blvd from Lake to Moss St. and the alley south of Magnolia Blvd. between Lake and Victory will start during the summer of 2007. The work will be completed by December 31, 2007, including all station getaways at Lake St. between Olive Ave. and Orange Grove Ave. The foundation and equipment pad construction will start in late June or early July 2007, and will continue until December 2007. Major equipment delivery is estimated between December 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. All 4,160-volt load directly served from Burbank Station will be transferred and de-energized, all station equipment physically removed, and the station demolished by June 30, 2010.
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.
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 work is in progress.
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. 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 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 March 13, 2007 meeting. BWP has negotiated the price, terms and conditions of the agreement with ABB Inc. During negotiations ABB suggested we further improve the design of the direct connection between the transfer bus and low side of power transformers by adding disconnect switches. That will greatly improve the restoration time. As of May 31, 2007, the contract has been signed by both ABB and BWP and been submitted to the Purchasing Division with bonds and insurance for review and issuing of the purchase order. After the purchase order is issued, ABB will order a capacitor bank, circuit breakers, disconnect switches and other long lead items. Construction is expected to start in late Fall 2007 or early Winter 2008, and be completed before May 1, 2008.
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, all customer stations have 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. Reconductoring of the overhead portion of the A-8 and A-96 feeders are complete. We are planning to convert Feeder A-8 and a portion of the Feeder A-96 load to Hollywood Way-4 in June 2007.
Progress continues on single pole replacements. Rebuilding deteriorated pole lines will start as soon as the reconductoring work is complete.
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 we lose a big generation source such as the tie with LADWP or MPP.
Customer Transformer Stations
Since July, Engineering has responded to 137 written requests for review and comments from the Community Development Department and other City Departments.
New business, and a strong residential real estate market, has created a demand for new customer stations.
Two vault-type customer stations have been removed and will be replaced by padmount switch/padmount transformer services. Both designs will contribute to the expansion of the underground loop system.
Undergrounding
The City Council approved the establishment of the first Underground Utility District within the City of Burbank for Olive Ave. between Victory and the I-5 overpass. Construction started in early April and is progressing very well. Except for final paving, J Fletcher Creamer has completed most of the underground conduit work at Lake St. between Olive Ave. and Orange Grove Ave., and along Orange Grove Ave. except for a small crossing. They also completed underground conduit work in the alley north of Olive Ave. and east of Victory Blvd. behind the 7-11 store. They installed manholes at Victory Blvd., both north and south of the Olive Ave. intersection, and are currently working on conduit installation in three separate locations in order to complete the work on schedule. In the mean time, the Okonite Company has delivered all of the 69,000-volt cable to the BWP Campus. The undergrounding for Phase-1 will be complete by October 31, 2007.
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 started work at Riverside Dr., between Olive Ave. and Hollywood Way, and modified the communication pull box in front of the Alameda Distributing Station to allow space for adding an east bound right hand lane between Hollywood Way and the proposed on-ramp. Bock Company will continue to support BWP as needed to meet the schedule of the Caltrans Project. As of June 8, 2007 Bock Company has completed most of the work along Riverside Dr. between Olive Ave. and Hollywood Way.
Streetlighting System
Fiscal year-to-date, 69 streetlight standards and 19 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. In April, Engineering issued a work order to replace five rusted out streetlight standards. 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 is almost complete on Empire Ave. Undergrounding of the streetlight system on Olive Ave. is complete.
Customer Service
Water Festival
On May 12, 2007, Burbank Water and Power celebrated its first ever Water Festival in conjunction with the Burbank Fire Department�s Fire Service Day. Over 700 Burbank residents of all ages came to see and learn about water, water conservation, special rebate programs and other water related booths and exhibits. Special water-saving items such as buckets, drip irrigation kits, low-flow shower heads and aerators were given to attendees as well as a variety of water-related literature. Special performances by the National Theatre for Children taught children the value and importance of water conservation. A packed 40x30 foot canopy echoed with the excitement and enthusiasm of children who watched the performances. Also at the Water Festival was a recruitment booth with job applications and information for entry-level opportunities at BWP. At least 15 BWP staff, and over 18 volunteers, participated in making the 2007 Water Festival a success!
