Central Contra Costa Sanitary District ` BOARD OF DIRECTORS POSITION PAPER Board Meeting Date: January 21, 2010 No.: = 5.a. Operations Type of Action: ACCEPTANCE OF REPORT Subject: BOARD ACCEPTANCE OF THE 2009 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM ANNUAL REPORT Submitted By: Initiating Dept./Div.: Bhupinder S. Dhaliwal, Plant Operations /Laboratory Laboratory Superintendent REVIEWED AND RECOMMENDED FOR BOARD ACTION: Sl~ L,/ ~ `-% may' B. Dhaliwal Craig James Ily, General M pager ISSUE: The Central Contra Costa Sanitary District's (District) 2009 National Pollutant Discharge Elimination System (NPDES) Annual Report has been prepared for submission to the California Regional Water Quality Control Board (RWOCB), San Francisco Bay Section. This annual report is presented for the District Board of Directors' information and acceptance. The Sewer System Overflow and Recycled Water Annual Reports will be submitted separately at later dates. , RECOMMENDATION: Accept the 2009 NPDES Annual Report. FINANCIAL IMPACTS: None ALTERNATIVES/CONSIDERATIONS: None BACKGROUND: During 2009 the treatment plant received a total of 14.1 .billion gallons of wastewater, which equates to an average flow of 38.6 million gallons per day. This average flow is approximately 6 percent less than year 2008. The treatment plant produced an effluent with annual average carbonaceous biochemical oxygen demand (C-BOD) and total-suspended solids (TSS) concentrations of 6 mg/L and 8 mg/L, respectively. These concentrations are markedly lower than our NPDES permit standards of 25 and 30 mg/L, respectively. C-BOD and TSS removal efficiency for the treatment plant averaged 97 percent and 96 percent, respectively. Approximately 3,900 tons of furnace ash was produced in the District's multiple-hearth furnaces. The ash met regulatory requirements for final disposal throughout the year. Once again this year, more than 15,000 NPDES permit-required tests were completed to comply with the NPDES permit requirements. The treatment plant effluent met all (100 percent) of the NPDES permit requirements throughout the year.

The NPDES report presents yearly totals, averages, and maximum and minimum values of Central Contra Costa Sanitary District's (CCCSD) influent, final effluent, sludge, ash, and receiving water quality parameters. All sampling and analyses were performed in accordance with Regional Water Quality Control Board (RWQCB) Order No. 82-2007- 0008. The final effluent quality remained in compliance with all applicable National Pollutant Discharge Elimination System (NPDES) standards. On July 7, 2009, the effluent sample was tested for the required red abalone chronic toxicity. The contract laboratory reported a toxic unit (TU) of 19.6. The laboratory however, reported an ammonia-N concentration of tested effluent at 34.5 mg/L. Since this concentration was outside the typical effluent concentration range of 24-28 mg/L, the sample was presumed to be contaminated. On July 22 another sample was tested; however, the concurrent reference toxicant data for this sample did not meet the acceptable quality assurance and quality control criteria. Yet another sample was collected on July 29 and tested at another laboratory for red abalone toxicity. However, this test also failed because of unacceptable development abnormalities in the control. Subsequently, the first (routine) contract laboratory reported that they had originally reported ammonia-N concentration erroneously. The corrected ammonia-N was indeed within the expected range. Assuming the first test was valid, the inclusion of 19.6 TU in the database resulted in athree-sample median of 10.6 TU, triggering accelerated monitoring. As a part of an accelerated chronic toxicity monitoring program, the effluent was tested for red abalone chronic toxicity on September 24, October 20, and November 4, 2009. The three-sample median remained greater than 10 TU; consequently, a toxicity identification evaluation (TIE) was initiated. The TIE revealed that the toxicity to red abalone was caused by increased effluent ammonia-N. Since 2007 the effluent ammonia-N concentration during the summer and fall period has steadily increased. This increase is likely due to a combination of water conservation and reduced inflow and infiltration N:\POSUP\Laboratory\Annual Report-2009\Discharge Summary 09-BSD.doc Dischargers Monitoring Program Annual Report Summary of Comments and Significant Events - 2009 Page 2 January 14, 2010 (dilution) resulting from the ongoing drought over the last three years. In the summer and fall of 2009, the effluent ammonia-N concentration exceeded the red abalone toxicity thresholds. A detailed TIE report was submitted to the Regional Water Quality Control Board separately. For dioxin analyses, CCCSD split its samples between two laboratories. The results reported herein are the average reported values from the two laboratories. In the case where one laboratory reported a numerical value and the other reported "Not Detected" (ND), the reported value was the average of the numerical value and detection level of the laboratory reporting the ND. In the case where the detection level of the laboratory reporting ND was higher than the numerical value, only the numerical value was reported. All analyses reported herein were conducted at CCCSD's laboratory, except the pesticides, dioxin, polynuclear aromatic hydrocarbons (PAHs), and chronic toxicity. These analyses were performed at CCCSD-contracted laboratories. These laboratories are certified by the Department of Health to perform these analyses. Operations and Maintenance Procedures The NPDES Permit, Section VI, paragraphs 5.b.(2) and (3), Operations and Maintenance Manual, states, "The Dischargers shall regularly review, revise or update, as necessary, its operations and maintenance manual...." CCCSD's operations and maintenance procedures, known as the Plant Information Management System (PIMS), continues to be updated including the addition of new features. The in-house managed site continues to be expanded in content and complexity in 2009. The overall content of PIMS is 160 GB, with over 100 GB of that being video. The treatment plant-specific training videos pertain to treatment plant system upgrades, equipment upgrades and modifications, and mandatory treatment plant training material used for plant operator certification. Procedures and guidelines continue to be updated as changes occurr, usually in the form of text illustrated with embedded photos or video clips. A new 360-degree panoramic feature has been added to PIMS, allowing a virtual display of various location within the treatment plant. After a comprehensive review of all training videos, a process has begun to upgrade outdated videos and their associated certification tests. This process, filmed in high quality HD, incorporates the changes that have taken place since the original videos were first filmed. PIMS also links to the administrative portion of the District Intranet and to the treatment plant geographic data interface (GDI) site, which contains information on plant construction. The website also links directly to the Internet to provide information such as real time weather data, treatment plant operator certification requirements, and treatment plant remote camera displays.

FREITAS, HUMAN RESOURCES MANAGER~/j DEBORAH RATCLIFF, CONTROLLER ~,L SUBJECT: CCCERA JANUARY 11, 2010 BOARD MEETING UPDATE (Agenda Item 7.a.1.a) The Contra Costa County Employees' Retirement Association (CCCERA) met in open session from 9 a.m. to 1 p.m. at the Concord Hilton on January 11, 2010. There were approximately five hundred attendees, most of whom were retirees, current employees and staffs of the sixteen member agencies in the retirement system. The Central Contra Costa Sanitary District (District) had about ten retirees, six employees and four staff. Board President Michael McGill also attended the meeting. Attached are several documents for your review: 1. Attachment A is the hand-out from the Legal Counsel's PowerPoint presentation 2. Attachment B is the official description from the CCCERA website of their role and function 3. Attachment C is the list of CCCERA Board Members 4. Attachment D is the January 12, 2010 Contra Costa Times article about the meeting Meeting Summary The first hour and a half was devoted to Reed Smith Counsel Harvey Liederman's presentation. (Mr. Lieberman wrote the October 2009 legal opinion to CCCERA which addressed the vacation accumulation pay-off being counted twice during the final year.) His main points were: • There have been four court cases (not on vacation leave payouts) which suggest that "'distortions' caused by inclusion of terminal pay and final year conversions of non-cash items to cash" can be eliminated. • CCCERA should consider if final year conversions and incentives are payable only at termination, how much leave accruals paid at termination should be included, and should "straddling" two fiscal years be allowed. • CCCERA could determine that they made an error in 1998, when they took Board action to allow the pay-offs. • If an error was made, retirees and employees would not have vested rights to the additional compensation resulting from the error. • CCCERA is responsible for determining what is a lawful benefit to be included in final average salary. Directly following Mr. Liederman, CCCERA Retirement Chief Executive Officer Marilyn Leedom spoke about CCCERA's practices and policies. She acknowledged that in 1998, CCCERA adopted a policy which permits the enhancement of final average salary (FAS) with the payment of two vacation accumulations, and vacation and sick leave paid at termination during the last twelve months of employment. Furthermore, she stated that it has been the practice of CCCERA to inform its members of this practice on the web and in annual member statements, the employee handbook, twelve retirement planning seminars held each year, and individual counseling sessions. Various CCCERA Board Members took the position that CCCERA is merely a trustee for funds contributed by the member agencies. 'Some CCCERA Board Members opined that it is up to the member agencies, not CCCERA, to change any benefits received by their employees. Additionally, some CCCERA Board Members believe that the current retirees and employees have vested rights to the CCCERA policy established in 1998; changes to the policy could only be made for future employees. One previous CCCERA Board Member, Bill Cullen (a twenty-four year veteran of the CCCERA Board) spoke for the record saying that no errors had been made by the previous CCCERA Board. They had legal and actuarial opinions and numerous Board meetings where the subject was deliberated. Moreover, for the past thirteen years, member agencies and employees have been charged in their rates for the financial impact of the policy. The attorney who represented the plaintiffs in Paulsen also attended the meeting and stated that.the law prevents current retirees from being touched by any change in policy and pension benefits are fixed on hiring for current employees, unless a comparable benefit is given. The retirement benefits have been earned and paid for. Christine Hunt, Executive Director of the Contra Costa Taxpayers, asked if the policy was a mistake. She believes current retirees and employees should be affected by an immediate change in policy. The next discussion will take place in Closed Session at the CCCERA Board meeting on January 27, 2010. It is unclear vvhat action, if any, CCCERA will take.

Monday implored their. pension board. riot to change, established rules governing pension calculations.,- . The pleas came at a Contra Costa Employee Retirement Association meeting that drew 500 people, many of whom expressed indignation at board attorney Harvey Leiderman's waminga about the legality of the calculations. He reviewed court rulings that said pension boards are not required to permit end-of-career salary enhancements -such as selling back vacation time - to calculate highest annual salary in determining ension payouts ,, - ~ '- 'This board is responsifile to the retirees, riot to the general public," said Rollie Katz, business agent of Public Employees Local 1, the county's largest union. 'These are vested rights, and we've, relied on what we've been told about what we are owed:'. However, theJeader ofa Contra Costa taxpayer advocacy groupsaid that the pen§ion board, and" system might be liable for"a lainrsuit.from taxpayers or the county if nothing is done. "Leiderman laid out things very clearly that things have changed based on these judicial decisions," said Kris Hunt, executive director of the Contra Costa Taxpayer Association. "He was telling them that there could be a problem if they don't take corrective action." At issue is whether the board can rescind pension benefits and perhaps even attempt to recover money paid out over the past decade. Leiderman invoked attorney-client privilege in response to a question over the possibility of the association being a target of a lawsuit, and the board also declined to discuss that issue. Attachment D One of the key policies questioned gives.employees the' right to lake pension credit for as much as two years of paid,vacation duririg,theirhlghest-paid, year. Leidermah told the board and"retirees that' ~, '~ appeals coorf rulings Have changed the, rules that . 'required assoaations fo_allow that and other things. A policy based on a mistake iri interpreting the law could be challenged in court, he said. Leiderman has recommended that the board determine if association policies should be changed to reflect current law and decide whether benefits should be recalculated. If the pension board acts on Leiderman's analysis, it could.ask employees,to refund; extra.pensiom, ,. payments they,,have receroed sirice 1997 basedom. revised credits: It also'couid,r`egise projected payments for current workers or establish different rules for new workers. Several speakers said it would be unfair to reverse ' pension.commitments based'on court`decisionsi r_. `. made in 2003:and 2004 that were not recognized at the time They said they had made a choice to retire. " at the time they did based on what they were told:`" they would receive: '~ -~ "If you change the policy, that would be a mistake,' said Bill Cullen, a retiree and fanner pension board member. "The money was paid during the final 12 months of service, then it should be included." The board may schedule another open meeting to discuss the issue further. 7, a, ~ b~ Central Contra Costa Sanitary District January 15, 2010 TO: HONORABLE BOARD OF DIRECTORS FROM: JAMES M. KELLY, GENERAL MANAGER /~~~ SUBJECT:- CCCERA LETTER ILLUSTRATING IMPACT OF DE-POOLING (Agenda Item 7.a.1.b) In October, the Contra Costa County Employees' Retirement Association (CCCERA) took action to de-pool their assets, Unfunded Actuarial Accrued Liability (UAAL) and liability by employer, for determining employer contribution rates. CCCERA's actuary, The Segal Company, prepared the attached letter analysis (dated January 6, 2010) to illustrate the effect of de-pooling on employers' contribution rate. Segal used last year's rates for the illustration, and they did not show the impact on safety contributions. A discussion of de- pooling and this letter was on the agenda for CCCERA's January 13, 2010 meeting; staff attended this meeting. In sum, the illustration showed the District's employer contribution rate would go up 3.94% of salary costs or about 13% total retirement contribution ($1,000,000 more per year). This would not be implemented until 2011-12 at the earliest. Staff is seeking more detailed data supporting the calculations in an effort to understand the actuary's calculations and ensure fairness to the District. Staff will update the Board at the Financial Workshop on January 21, 2010, if new information is available.

Appendix II shows the employer contribution rates from the December 31, 2008 actuarial valuation both before and after depooling. The rest of this letter contains background information on the action taken by the Board and how the illustrative employer contribution rates after depooling have been determined. At this time we are only showing the impact on the General contribution rates" This is due to the prior inclusion of various fire districts data in County payroll. We are working with CCCERA to verify the accuracy of the data that was provided for nonactive Safety members. The Safety results will be determined and released once this process has been completed. Background At its October 14, 2009 meeting, the Board took action to depool CCCERA's assets, AAL and Normal Cost by employer for determining employer contribution rates" However, the smaller employers (those with less than 50 active members) will be pooled with the applicable County tier.

We also understand that they had 48 active Safety members as of December 31, 2009. Therefore, we have pooled this employer with the County Safety Tier A Enhanced cost group and will continue to monitor the number of active Safety members at this employer to see if creating a separate cost group would be justified in the future. Due to a statutory requirement, the Superior Court will continue to be pooled with the County regardless of how many members the Court has. The three employers that terminated participation with CCCERA in the last decade and still have nonactive members in CCCERA were pooled with the applicable County tier. These employers are subject to additional contributions depending on their funded status that is measured every, three years. Overall, there is little impact on employer contribution rates either way (pooled or not pooled) due to the small size of the assets and liabilities associated with these employers. Appendix I shows the resulting twelve cost groups and the employers included in each cost group. The Board action also included a retroactive application of the depooling back to December 31, 2002. This retroactive approach would not involve recalculation of employer rates prior to December 31, 2008. However, it would involve reflecting the separate experience of the employers in each individual cost group back to December 31, 2002. Note that in these calculations we have used an implementation date of December 31, 2008 to illustrate the effect of this depooling as if it were implemented on that date, on a retroactive basis. In practice, the implementation date will be December 31, 2009, so as to avoid changing the rates that were already adopted based on the already completed December 31, 2008 valuation. The first actual employer rates affected by depooling would be those in the December 31, 2009 valuation. There were also two specific cost sharing adjustments that will be removed as of the implementation date of December 31, 2009. These adjustments are for General Tier 1 and Safety Tier A as follows: > Non-enhanced General Tier 1 and Non-enhanced Safety Tier A members shared their combined member COLA normal costs in proportion to their basic member contribution rates > General Tier 1 and Safety Tier A employers shared COLA normal cost in the same way that member COLA contributions are shared (i.e., by allocating COLA normal costs in 5063391v1/05337.001 _~ Ms. Marilyn Leedom January 6, 2010 Page 3 proportion to basic normal costs). These costs were shared equally among member classifications with comparable benefit levels (i.e., enhanced versus non-enhanced) Note that the first adjustment affects member contribution rates and has not been determined as part of this study. However, this will only impact the fewer than 30 active members that are in either Non-enhanced General Tier 1 orNon-enhanced Safety Tier A. Closed Cost Groups and Pooling of Unfunded Actuarial Accrued Liability (UAAL) There are two cost groups that currently have active members, but are generally closed to new members. As listed in Appendix I, these are cost groups number 1 (County General Tier 1 Enhanced) and number 7 (County Safety Tier A Enhanced). If the UAAL for these two cost groups is not pooled with another cost group that is open to new active members then the UAAL rate for these generally closed cost groups would increase substantially in future years. This is because the UAAL for CCCERA is amortized as a level percent of payroll and the payroll growth for the generally closed cost group would be less than the payroll growth assumption (currently 4.25%). For County General Tier 1 Enhanced this would ultimately lead to large UAAL rates being borne by the very small district employers in that Tier. This is due to the payroll growth issue mentioned above caused by the closed group nature of the County in Tier 1. However, the small district employers in that tier still continue to add new active members and eventually will represent the bulk of the active members in that tier. Combining this with the large retired member liability in that tier that is mostly from former County employees leads to the impractical result that the small district employers would bear the potential impact of the volatility in rates associated with the large County retiree liability. In order to avoid associating a large County retiree liability with the small district payroll, we have pooled the UAAL for County General Tier 1 Enhanced and County General Tier 3 Enhanced (cost groups 1 and 2) in the determination of the employer contribution rates (in the after depooling scenario). Normal Cost rates for these cost groups will not be pooled since they will not be affected as much by the issues mentioned above. Note that the benefit formulas for General Tier 1 Enhanced and General Tier 3 Enhanced differ only because of the disability benefit paid. Therefore, there will be a small amount of cross- subsidization occurring because of this pooling. For County Safety Tier A Enhanced, there is only one other small employer in that cost group (East Contra Costa Fire Protection District) and there are very few new active members entering this tier. The County Safety Tier C cost group only has the County as an employer. Therefore, in order to produce more stable UAAL rates for the County Safety Tier A Enhanced cost group, we have pooled the UAAL for County Safety Tier A Enhanced and County Safety 5063391v1/05337.001 Ms. Marilyn Leedom January 6, 2010 Page 4 Tier C.Enhanced (cost groups 7 and 9). Normal Cost rates for those cost groups will not be pooled. There are some substantial differences between the Safety Tier A Enhanced and Safety Tier C Enhanced benefits, such as the period over which final average salaries are determined and the COLA. However, since the County is by far the largest employer in these two cost groups, they will be the employer affected by this particular pooling. In addition, the East Contra Costa Fire Protection District will benefit from the more stable "pooled" UAAL rates. Process Used in Determining Illustrative Employer Contribution Rates (After Depooling) There are three key stages in the process used to determine the illustrative employer contribution rates as of December 31, 2008 after depooling. Those stages are as follows: > Initial allocation of assets by employer at December 31, 2002 . > Roll forward of assets for each employer from December 31, 2002 through December 31, 2008 > Calculation of illustrative employer contribution rates at December 31, 2008 Information on each of the stages is described below. Initial Allocation of Assets by Employer at December 31, 2002 To determine the initial allocation of assets for each employer as of December 31, 2002 we had to first determine the December 31, 2002 liabilities as of that date for every employer. This required obtaining data from the Retirement Association that denotes the employer for each retired member as this data did not exist in the original December 31, 2002 data used for that valuation. We then used our valuation software to determine liabilities for each employer as of December 31, 2002 consistent with the liabilities determined in the December 31, 2002 actuarial valuation. Once the December 31, 2002 liabilities by employer were determined, we then allocated enough assets to each cost group in such a way as to result in the same UAAL contribution rate that was already determined in the December 31, 2002 valuation for every employer. Roll forward of assets for each employer from December 31, 2002 through December 31, 2008 506339Iv1/05337.001 _; Ms. Marilyn Leedom January 6,.2010 Page 5 The assets that were allocated to each employer at December 31, 2002 were then "rolled forward" by adding in contributions and allocated investment income and subtracting benefit payments., This was done on an annual basis for the 2003 through 2008 calendar years. The contribution and benefit payment information was provided by the Retirement Association and accepted by Segal without audit. Calculation of employer contribution rates at December 31, 2008 The assets as of December 31, 2008 for each employer were then combined into the twelve cost groups. Liabilities as of the same date were also separated in the twelve cost groups based on the actual current members in each group. Employer contribution rates were then calculated for each cost group following substantially the same process used in the annual actuarial valuation. Any change in the December 31, 2008 UAAL due to depooling was amortized over 18 years. Please note that district contribution rates still reflect the fact that they did not issue pension obligation bonds (POBs) when the County did. The contribution rates for the Moraga-Orinda Fire District or the Contra Costa County Fire Protection District also reflect any POBs or special contributions that were deposited in prior years by those employers. Summary of Results Appendix II shows the employer contribution rate from the December 31, 2008 actuarial valuation and the illustrative employer contribution rate determined on the same valuation date after depooling. The rates are shown for each employer in CCCERA. As noted above, in these calculations we have used an implementation date of December 31, 2008 to illustrate the effect of this depooling as if it were implemented on that date, on a retroactive basis. In practice the implementation date will be December 31, 2009, so as to avoid changing the rates that were already adopted based on the already completed December 31, 2008 valuation. It is important to note that the results of depooling depend critically on the employer by employer contribution and benefit payment data, and on the employer by employer member data reported as of December 31, 2002 and December 31, 2008. Due to the prior inclusion of various fire districts data in County payroll, we are working with CCCERA to verify the accuracy of some of the data that was provided (mainly employer codes for nonactive Safety members). The results shown in Appendix II can be used to estimate the impact that depooling will have once it is implemented in the December 31, 2009 actuarial valuation. However, the actual impact of depooling will not be known until it is implemented in that actuarial valuation. 5063391 v 005337.001 4, Ms. Marilyn Leedom January 6, 2010 Page 6 Note that this "retroactive" approach did not require or involve recalculation of employer rates prior to December 31, 2008. Only employer contribution rates on and after the implementation date would be affected, but now those rates reflect the separate experience of the cost groups back to December 31, 2002. These calculations were based on the December 31, 2008 actuarial valuation for CCCERA, member data as of December 31, 2002 and December 31, 2008 provided by CCCERA and contribution and benefit payment information from January 1, 2003 through December 31, 2008 that was also provided by CCCERA. The December 31, 2008 actuarial valuation and these calculations were completed under the supervision of John Monroe, ASA, MAAA, Enrolled Actuary.

The fire training will involve firemen in complete fire fighting gear, breaking through closed doors and walls, and using charged hoses within the structure. Hazardous materials are currently being abated and once this has been completed, the building will be ready for training. Training will occur the last week in January. Awards b) San Francisco Bay Section of the California Water Environment Association Awards At the 60th Annual Awards and Installation Banquet on Friday, January 8, 2010, the District received three achievement awards. Maintenance Supervisor Paul Louis received the Special-Service Award in recognition of his long-term dedication and special service; the mercury pilot study received the Research Achievement Award which was spearheaded by Associate Engineer Craig Mizutani; and Senior Engineer Ba Than received the Supervisor of the Year Award. The Research Achievement and Supervisor of the Year Awards will be competed at the State level. These awards will be presented to the Board of Directors at a future meeting. General Information/Updates c) Public Records Act Request for Employee Salaries On January 7, 2010, the District received a Public Records Act request from Thomas Peele, Bay Area News Group, asking for a list of all full and part-time employees by name, their base salaries for 2009, overtime, other payments that contribute to taxable gross pay, and total gross salary. This is the same information that he requested of public agencies last year, but at that time the District was not included in his request. If Mr. Peele proceeds as he did last year, the list will be made available through a link on the Contra Costa Times website. He also graded agencies on their response (see attached article). Staff has confirmed with legal counsel that all of the requested data is public record. The data is being assembled and will be provided to Mr. Peele within the ten-day period legally permitted for response to public records requests (no later than Friday, January 15). All employees will be informed that this information has been released to the press. d) GroupWise Email System Update The District GroupWise email system was down from Tuesday morning, January 5 through Thursday afternoon, January 7, 2010. Since that time, the email system has been functioning properly and all incoming Internet emails sent to the District during the downtime were processed and received. System improvement suggestions will be presented to the Board at a future meeting after the matter is brought to a future Budget and Finance Committee meeting.

CON~'RA C~STATI~~ES CvntraCostaTlmos.cam ~, a BANG Watchdog: Some Bay Area governments were stubborn with releasing their records By Thomas Peele Watchdog columnist Posted: 12/27/2009 12:00:00 AM-PST Updated: 12/29/2009 10:59:16 AM PST Database . • Browse our public employee salary database IN 2009, we managed to gather salary data on more than 188,000 local public employees from 96 Bay Area government agencies, posting the information on our online site at www.contracostatimes. com/publ is-em ployee-salaries. The vast majority of governments quickly and efficiently provided the information. A few didn't. Some complained about the format I had requested from them. I asked for the data in a spreadsheet in order to easilydisplay it to taxpayers: ', If we had graded governments on how they responded to the Public Records Act requests, Alameda County, Walnut Creek; Oakland, BART and San Francisco were among the entities that would have gotten A's. Alameda (the city), San' Ramon; Albariy and ~ . Campbell were among those that would have been graded F. Reasons for these harsh assessments vary from a failure to respond to a letter asking for the data within the required 10 days to balking over the format. Then there was Redwood City -the last government to cough up 2008 salaries. City officials there finally backed down after months of recalciUance and provided an Excel spreadsheet of workers' 2008 salaries two weeks ago. I had first asked for it in early October after officials refused to provide the data to the San Mateo County Times. Given the responses to my routine Public Records Act request, ohe might have the thought.Redwdod City was the CIA and 1 wanted the names of covert agents.. When I pointed out to then-Mayor Rosanrie FousYthat the city wasn't releasing the data, she' didn't do anything to help. Other council members didn't even answer a-mails about it. Neither did City Manager Peter Ingram. All City Clerk Silvia Vonderlinden would say is that the . city wanted money, claiming it would cost nearly $300 to prepare the data. Redwood City already had the data and has no right to charge for it. Clearly, the city knew the names of its employees, their job titles, their departments, their base pay, overtime and any other pay they received in 2008: Voriderlinden even claimed the city could charge.fees just to let me look at the data . in the electronic format ih which it is kept. All I asked the governments to do was put existing salary records in a spreadsheet so it could be easily uriderstood and displayed. All this takes is cutting and pasting.: Trust me, iYs sd simple even I can do it.

CUN~CRA CO~J u 1~C~[NI~S Cont-aCostaTimos.cam expect of local government. Still, Redwood City officials refused. It took phone calls and a letter from our lawyer, Karl Olson, to finally convince them to back down. Given that he has argued the public nature of govemment salaries before 11 judges and all 11 agreed with this reasoning, telling Olson no on salary access is like invading Russia in winter: A major defeat is inevitable. But what does the need to involve lawyers over something this simple mean about cultures of transparency in local govemment? The California , Constitution, amehded by voters through - ., -, Proposition 59, requires that the default position of government officials sho2ild.tie to disclose information. People went to the ballot box and . ordered their governments to take down the " shrouds. Starting next month, we will begin collecting 2008 pay totals for all govemment agencies across the region, including school districts, and posting the information as quickly as possible. We also are planning to grade each entity on how well it complies with our requests and post those grades online and print them in our newspapers. You havearight to know. how7eadily the city '', . county and special districts that tax-you are willing to make public where your money goes. When a government balks over a release of expenditure records, especially electronic records, you have to ask why. .. Recently, the American Federation of State, County ;' ,' and Municipal Employees, or AFSCME, asked the _ ~' University of California for electronic records of the , .' expenditures of university officials,-contracts and vendor payments. University officials have demanded thousands of dollars in fees. AFSCME sued in June; the case is pending in Alameda County Superior Court. Given the fiscal crisis and rising tuition, one might think that UC officials would be happy to open the books. It is also quite curious that UC apparently has no central way of tracking expenditures -the reason officials cite for needing lots of time and money to fulfill AFSCME's request. AFSCME - or anyone else -should not have to pay for the government to provide sending data in a sensible way. The public should be demanding more accountability about how its money is spent = accountability carYonly rise from detailed disclosure. That's why the resistance to the release of electronic records from huge entities like UC and small ones like Redwood City is so troubling. There's only one question to ask when they claim they can't readily show where the money goes: What are they trying to hide?

The plant experienced a peak flow on Tuesday, January 19, of 121 MGD and a peak flow on Wednesday, January 20, of 142 MGD. On Tuesday, 6 million gallons of primary effluent were bypassed to the holding basins. This diverted flow was drained back and processed on Tuesday night. On Wednesday, more than 6 million gallons of primary effluent were bypassed to the holding basins. All of this diverted flow was drained back by Thursday morning. The total influent flow for the three days was about 197 million gallons, or 66 MGD. On Wednesday, the flow through the ultraviolet (UV) disinfection system approached 120 MGD for a short time. This is the maximum flow we have processed through the UV system to date. During this peak flow period, Engineering and Operations staff observed the water surface elevations throughout the plant to determine if a flow rate of 120 MGD is sustainable for an extended period of time. It appears that some hydraulic issues may need to be. addressed. Collection System Total rainfall through 01/20/10 • Orinda Crossroads - 5.70 inches • Moraga - 4.70 inches • San Ramon -3.6 inches • Martinez - 4.5 inches In Pumping Stations West, most equipment performed to expectations; however, there were several control issues at Orinda Crossroads that were dealt with by Pumping Station Operations staff. Lower Orinda and Orinda Crossroads were in wet weather mode January 20, 2010. There was also some minor flooding along Camino Pablo, making access to the Flushkleen Station difficult. A Roto-Rooter hydro contracted by the Ciry of Orinda unplugged the storm drain, alleviating the problem. For Pumping Stations North, the Martinez Pump Station has operated in wet weather most of the week and at times, we have had two pumps running at various stations elsewhere in PS North. A short term power outage was experienced at Maltby, due to fuses popping on power poles leading to the station. The generator ran for approximately 4 hours and performed as expected. On January 20, there was asystem-wide problem with the SCADA system which disabled the normal automatic call function that alerts the on-call operator that there is an alarm condition. This required the shift supervisor to notify the PS staff of alarm conditions. The balance of the SCADA system continued to work. This problem was corrected at approximately 8:30 a.m. on January 21, 2010. Since the start of the storm through January 20, there have been four service calls regarding the Collection System; three during the day and one for the on-call crew. One of these was an overflow with a volume of 500 gallons in Orinda, with minimal property damage.
