CONSENT CALENDAR 6 SUBJECT AUlHORIZE lHE SUBCONTRACTING OF A PORTION OF lHE WORK ON lHE HALL DRIVE SEWER IMPROVEMENTS, PHASE-l PROJ ECT (DP 4331A) DATE March 2, 1990 TYPE OF ACTION AUlHORIZE ADDING OF SUBCONTRACTOR SUBMITTED BY Henry B. Than Associate Engineer INITIATING DEPT/DIV. Engineering Department/ Construction Division ISSUE: Board authorization is required for adding a subcontractor to perform work in excess of one-half of one percent of the prime contractor's total bid where no subcontractor was designated in the original bid. BACKGROUND: The Contractor, Ranger Pi peli nes, Inc., is proposi ng to bore and jack a 500 (+) foot section of the deepest portion of the pipeline along Hall Drive in 1 ieu of the original open trench excavation design. The subcontractor being proposed for the work is Pacific Boring, Inc. (PBI) from Caruthers, California. PBI has performed satisfactorily in a recent District project. Under Public Contract Code Section 4109, the subcontracting of a portion of the work in excess of one-half of one percent of the total original bid is permitted only in cases of emergency or necessity. In the present instance, the alternative construction method being proposed by the Contractor will significantly reduce the traffic congestion in the Hall Drive area and, therefore, is in the best interest of the public and, in staff's judgment, "necessary." Staff concludes that the change of work method and the consent to such change by the Board is appropriate. Staff has negotiated a no cost change order to perform the work. The change order requires the Contractor to perform additional so11s investigation and to assume liability for the suitability of the subsurface soils condition for the operation.

Engineering Department/ Construction Division ISSUE: All work has been completed on the installation of the Influent Gate Operators Project (District Project 20070) and the project can now be closed out. BACKGROUND: The contract work included the installation of two new gate operators to control influent flow to the treatment plant with electrical and instrumentation modifications for both local and remote control (see attached map). The two gate operators were prepurchased by the District in August, 1988. This project is described in more detail in the 1988-89 Capital Improvement Budget on page TP-82. Amelco Electric was issued a Notice to Proceed on January 23, 1989. The original contract completion date was April 24, 1989. All work was completed and the District was able to take beneficial use on May 10, 1989. Time extensions were granted to establish a new contract completion date of May 10, 1989. Amelco Electric's contract was for $66,302.00. There was one no cost Change Order issued on the project resulting in a total payment of $66,302.00 to Amelco Electric. The total budget for the project was $145,400. The total completed project cost is $144,800 which is $600 less than the budget. Staff is closing out the project which will result in $600 being returned to the Treatment Plant Program. RECOMMENDATION: This item is presented to the Board for information.

Case Associate Engineer INITIATING DEPT/DIV. Engineering Department/ Planning Division ISSUE: Separate projects are no longer required for collection system planning in the District's 21 watershed areas, and these projects can now be closed out. BACKGROUND: The capital projects 1 isted on Attachment I were establ ished for planning trunk and pumping station facilities that were constructed in each of the Di stri ct' s 21 watershed areas. The pl anni ng, desi gn, and constructi on of facilities were funded by the watershed fees for each area. The District changed the connecti on fee system in 1989 and el imi nated Watershed Fees. The new fee system replaced the 21 watershed fees with a single fee for the entire collection system with a surcharge fee for areas served by pumpi ng stati ons. The new fee system allowed the 21 watershed projects to be replaced by one project; the new project has been established so the watershed planning projects may now be closed out. This will result in a return of $114,469 in unexpended funds to the Collection System Program of the Capital Improvement Budget.

Ken Roan, V&E Maintenance Supervisor Collection System Operations Department ISSUE: Board Authorization is required by the State of California prior to purchasing under the state's Cooperative Purchase Program. BACKGROUND: Each year the State of Cal ifornia solicits public bids for automobil es and trucks to meet thei r operati ng needs. The bi ds are solicited from potential suppliers by area within the state. For a minor fee, other government agencies can purchase vehicles under the state's contract at the price submitted by the lowest responsible bidder. The prices are below the local market due to the large volume of vehicles being purchased. Additionally, purchasing vehicles through the state contract saves the cost and labor involved in soliciting bids. The Board approved the purchase of ni ne vehicl es as part of the 1989/90 Equipment Budget. Six of the vehicles are available through the state's Cooperative Purchase Program. They are: 1 Light Utility Vehicle 1 Standard Pickup Truck 1 4-Wheel Drive Pickup Truck 3 Small Pickup Trucks These vehicles can be purchased for $71,403 under the state contract which is within the 1989/90 Equipment Budget.

Collection System Operations Department ISSUE: Approval of the Board of Directors is required for unbudgeted travel outside of California and/or where the expense will exceed $500. BACKGRCllND: The District's collection system is aging. Many of the small diameter sewers, installed early in the District's history, are in need of replacement or rehabilitation in order to control rapidly escalating maintenance requirements, structural failures, and high rates of inflow/infiltration. Joye Lynn Kurasaki, Associate Engineer at CSOD, is responsible for many decisions regardi ng the operati onal aspects of new sewers and the repl acement of the 01 der sewers. The ASCE Conference on Pipeline Design and Installation to be held on March 25-27, 1990, in Las Vegas, Nevada, will provide an excellent opportunity to gain insight into the latest information. The conference technical sessions include pipe material performance, current research on methods and materials, soil loads on buried pipelines, and cost analysis. The cost of attendance at this conference would be $815 for travel, lodging, and registration. The cost of this conference was not included in the 1989/90 O&M budget. There are adequate funds in the CSOD Technical Training, Conferences, and Meetings Account to cover the cost of this conference.

BAa<GROOND: State 1 egi sl ati on, 18 939, mandates stri ngent source reducti on and recycl i ng goal s by the years 1995 and 2000. Specifically, 25 percent of all sol i d waste must be diverted from landfills or transformation facil ities by January 1, 1995 and 50 percent by 2000. In 1989, the District, through the Regional Recycling Advisory Committee, implemented curbside recycling programs throughout our refuse collection franchise area. To date, all of the recycling programs are nearing full-scale implementation. At the Regional Recycling Advisory Committee meeting of February 21, 1990, a proposal was presented to undertake commerci al recycl ing programs as the next proj ect for the committee. There was a general consensus to move forward on commercial recycling, which will cover solid waste from multi-family residences and busi nesses, and represents 26.9 percent of the Contra Costa County Waste Stream, according to the 1989 CoSWMP (final revision). At this juncture in the committee's activities, it is apparent that specific commercial recycling plans to expand the existing single-family residential curbside recycling programs are needed to help achieve the State-mandated goals of 18 939. As our franchise agreements require that notification be given by the Board of Di rectors to i ni ti ate the desi gn of recycl i ng pl ans by the refuse coll ectors, a Board resol uti on has been prepared and is presented as an attachment to th i s Position Paper. The resolution requires that the refuse collectors develop their commercial recycling plans in concert with, and under the direction of, the Committee and District staff. Although the franchise agreement provides for 180 days for development of a recycling plan, the resolution requests that the refuse COllectors submit plans as soon as practicable to permit consideration of the financial effects of commercial recycling in the next refuse collection rate-setting process. REVIEWED AND RECOMMENDED FOR BOARD ACTION INITIATING DEPT.lDIV. 1302A-9/85 PM SUBJECT ADOPT A RESOLUTION DIRECTING THE DEVELOPMENT OF COMMERCIAL RECYQING PLANS BY THE DISTRICT'S FRANQ-nSED REFUSE COLLECTORS FOR THEIR SERV ICE AREAS POSITION PAPER PAGE 2 OF 2 DATE March 7, 1990 District staff recognizes that program implementation for commercial recycling is more involved than the programs for single-family curbside programs. Commercial recycling involves placing a variety of large recycling containers in a central location that is convenient to all participants at each multi-family residential establishment. In addition, specific efforts may have to be put in place to provide recycling service to local businesses. Moreover, commercial recycling may require more frequent pickups and more individualized communication efforts, as each establishment will have different requirements. To this end, upon receipt of an approved plan, the District would allow until June 30, 1991, for the franchised refuse coll ectors to compl ete full-seal e impl ementati on of commerci al recycl i ng in their respective areas. RECXMENDATION: Adopt a resolution to initiate the development of commercial recycling plans by the franchised refuse collectors for their respective service areas under the direction of the Central Contra Costa Sanitary District's staff and Regional Recycling Advisory Committee.

Engineering Department Engineering Division ISSUE: Authori zat i on by the Board of Di rectors is requ i red for the General Manager-Chief Engineer to execute professional engineering services agreements for amounts greater than $50,000. BACKGROUND: The Air Toxics "Hot Spots" Information and Assessment Act of 1987 inacted by the California legislature became effective July 1, 1988. The Act requires facilities meeting certain regulatory criteria to prepare and submit comprehensive air emission inventory plans and reports once every two years. The California Air Resources Board (CARB) has published regulations required by the Air Toxics "Hot Spots" Act. Under these regulations, affected facilities must submit an Air Toxic Emission Inventory Plan to their local Air Quality Management District or Air Pollution Control District. The plans outline how toxic air emissions from the facilities will be estimated. The Air Toxic Emission Inventory Report for each facil ity must then be submitted to the local Ai r District approximately ten months later. The report discloses the quantities of toxic emissions from each facility. Central San submitted its Emission Inventory Plan in August 1989. In order to prepare the Emission Inventory Report, a significant amount of data on toxic air emissions needs to be generated. On January 25, 1990, the Board approved the District's participation in the Pooled Emission Estimating Plan (PEEP) Program. The PEEP Program will provide a large portion of the data required for submission of the Emission Inventory Report. At that time the Board was also notified that the District's total cost for compliance with AB 2588 during the first two years of the act was estimated to be between $250,000 and $300,000. This cost included not only the costs for the PEEP Program but also the cost for the development of the Emission Inventory Plan, conducting specific source testing not covered by the PEEP Program, plus preparation of the Emission Inventory Report to be submitted to the Bay Area Air Quality Management District (BAAQMD). Funding for compliance with AB 2588 will come from the plant's Technical Services budget. An agreement has been negotiated with CH2M Hill Consulting Engineers to complete specific source testing not covered by the PEEP Program plus prepare the District's Emission Inventory Report. CH2M Hill was selected to do this work based on their familiarity with AB 2588, their experience in doing the same type of work for several other publicly-owned treatment works in the Bay area, plus their past performance in assisting staff in submitting the Emission Inventory Plan to the BAAQMD. The agreement for the work has a cost ceiling of $109,600.

TREATMENT PLANT 1 SUBJECT DATE BOARD ACCEPTANCE OF THE 1989 SELF-MONITORING PROGRAM REPORT Ma rch 9, 1990 TYPE OF ACTION ACCEPTANCE OF REPORT SUBMITTED BY Charl es W. Batts Plant Operations Department Manager INITIATING DEPT./DIV. Plant Operations Department ISSUE: The Central Contra Costa Sanitary District's Self-Monitoring Program annual report for 1989 has been prepared for submission to the California Regional Water Quality Control Board, San Franci sco Bay Secti on. Thi s report is presented to the Board at this time for its information and acceptance. BACKGROUND: The treatment plant continued to meet all effl uent requi rements throughout the year, with the exception of total coliform violations during five episodes and one settleable solids violation. The reason for the coliform violations is not fully understood. In each case there were no process upset conditions, and the chlorine dose and residual indicated that good effluent di si nfaction shoul d have occurred. Research was done on several potenti al causes but with no clear cause and effect results. There was one bioassay toxicity test where it is believed that chlorinated water entered the test chamber during system maintenance. The bioassay test was immedi ately restarted with new fish and showed no effl uent toxi ci ty. There were also 30 non-zero ch 1 ori ne resi dua 1 vi 01 ati ons. However, only six exceeded the Regional Water Qual ity Control Board's guidel ine concentrations. The majority of these violations over the last several years was related to problems of process control. Plant Operations Department staff is presently working on several projects to improve both the residual detection i nstrumentati on and computer dech 1 ori nati on programs and reduce future viol ati ons. The District performed routine monitoring of selected organic and metallic contaminants as requested by the Regional Water Qual ity Control Board. In 1989 additional monitoring in terms of both the frequency and the type of tests was added to the requi rements of the District. The results of these tests show that these contaminants were not detected in the treatment plant effluent in any significant concentrations and met all National Pollutant Discharge Elimination System (NPDES) permit standards. There was a total of 13,688 mill ion gallons of wastewater treated for an average daily flow of 37.5 million gallons. This flow is approximately the same as for 1988 and 5 percent lower than 1987 due to the recent dry winters. The treatment plant operated throughout the year and produced an effluent with an average BOD and total suspended solids concentration of 5 mg/l and 9 mg/l, respectively. This is markedly lower than our NPDES permit standards of 25/30 mg/l and an 89 percent removal efficiency. The BOD and total suspended solids removal efficiency for the plant averaged 97 and 95 percent, respectively. INIT REVIEWED AND RECOMMENDED FOR BOARD ACTION 1302A-9/85 CENlRAL CONTRA COSTA SANITARY DISTRICT DISatARGERS MONITORING PROGRAM REPORT REPORTING DISCHARGER Central Contra Costa Sanitary District DATE OF REPORT: February 14, 1990 RESOLUTION: 84-77 and 89-170 REPORTING PERIOD: January - December 1989 CO~ENTS : Enclosed is the 1989 annual report. The report presents yearly totals, averages, maximum and minimum values of the District's influent, final effluent, sludge, ash, and receiving water quality parameters. Important data are also presented graphically. All sampling analyses were performed in accordance with the Regional Water Qual ity Control Board's (RWQ(B) Reso1 ution No. 84-77 and 89-170. The final effluent quality remained in compliance with applicable NPDES standards except for 30 non-zero chlorine residual, one settleable solids, one fish bioassay and 24 total coliform violations. The maximum and minimum chlorine residual readings recorded were 9.5 and 0.4 mg/1, respectively. The total duration of the violations was 3.7 hours out of 8,760 hours (0.042 percent) of continuous monitoring by on-line chlorine residual analyzers. Most of the violations were caused by sudden and temporary dechlorination process control problems. It should be noted that the intensity and duration of most of these violations were so small that considering the 3.5 miles in length of the outfall, the chlorine residual probably never reached Suisun Bay to cause any harmful effects. The settleable solids violation occurred on September 18. This violation was caused by a sudden filamentous bacterial overgrowth in the activated sludge. Consequently, the sludge volume index (SVI> jumped to 600. This, in turn, caused the mixed liquor to overflow the secondary clarifier weir at peak flow, causing the violation. On March 8,1989, all 20 fathead minnows died in the effluent test chamber of the flow-through bioassay. On this day treatment plant Maintenance Division personnel were working on the sulfur dioxide injector. Because of low sulfur dioxide flow, the final effluent was diverted to the holding basins for a short time. However, some chlorinated effluent remained in the outfall and was accidentally pumped into the test chamber. Therefore, it is believed that a brief sl ug of chlorine in the effl uent to which the fish were exposed caused this toxicity. The test was restarted the same day with new fish and indicated no toxicity. The total col iform violations occurred at five times during the year. Two violations each occurred in March, April, and July. Five violations occurred in August, and eleven occurred in November. Except for one violation in November, which we believe was caused by insufficient chlorine residual, the causes of all other violations are not fully understood. All violations in March, April, July, August, and November, except for the one mentioned above, occurred under similar circumstances. Under each episode of these violations, the chlorine dosage to the effluent was normal, as was the case with the effluent chlorine residual. As a matter of fact, the chlorine residual was, in some cases, higher than the previous several days during which time the total coliform count was in compliance. Additionally, there were no apparent upsets in the secondary process, and the final effluent TSS and BOD concentrations were all nonnal (same as the previous several days when the coliform count was in control). For example, Figure A (page 1) shows the relationship of the final effluent total coliform count with the chlorine dose and residual from October 1 through December 15, 1989. As is evident from the figure for November 7 through 16, the average chlorine dosage and residual were about the same for the period of October 1 through November 6. However, the colifonn count was much higher. On December 2 the ch 1 ori ne dosage and ch 1 ori ne resi dual were dropped to a 1 evel well below the October 1 through November 6 period. To the contrary, the colifonn count actually dropped. Figure B (page 2) shows the relationship of total coliform with effluent TSS and BOD concentrations. As is evident from the figure, the final effluent TSS and BOD concentrations during the period of November 7 through November 16 were not significantly higher, as compared to the period of October 1 through October 30 or December 1 through December 15. This i ndi cates that there was no evi dent trea"bnent process upset that mi ght have contributed to this short period of poor effluent disinfection. Therefore, it appears that there are other vari abl e(s) that are yet unknown other than chlorine residual or BOD and TSS concentrations that contributed to the high coliform counts from November 7 through 16. Several potenti al causes were researched. contamination from the Filter Plant forebay. effluent into the Filter Plant forebay. One potential cause was outfall The District routinely diverts its There exi sts a chance of a val ve (connecting the forebay drain into the outfall) leak resulting in a reverse flow from the forebay to the outfall. It was believed that if the forebay water could have been enriched with coliform and leaked into the effluent, it might have contributed to these high coliform counts in the effluent. To test this hypothesis, water samples from the forebay were collected on several occasions. Each time the total coliform count in the forebay was less than 100 MAN/100 ml. Therefore, it was concluded that the forebay was not the source of these high coliform counts. Another potential cause was the contamination of final effluent by primary effl uent. The treatment pl ant flow schemati c, Fi gure C, (page 3) shows that there is a chance of a primary effluent leak into the final effluent by way of Valve 52-FE07. This valve separates the primary effluent from the final effluent and is locked shut. The likelihood of this leak is very minimal. A dye test is pl anned to test thi s hypothesi s. In the meantime we performed a simple bench test to test this hypothesis. A chlorinated final effluent sample from the effluent channel immediately downstream of the effluent chlorination was spiked with primary chlorinated effluent in 50:1 and 100:1 ratios (l part primary effluent and 50 or 100 parts chlorinated effluent). The spiked samples were held on the bench for 30 minutes. They were then dechlorinated and tested for total coliform. The results in the Table A (page 4) show that the addition of primary effluent (10 ml to 50 ml of chlorinated effluent) did not increase the total coliform of the effluent. This experiment shows that a 1 MGD leak of primary effl uent at the peak flow (50 MGD) usual sampl e time for effl uent coliform testing would not cause any significant increase in the effluent total coliform count. It is highly unlikely that Valve 52-FE07 would leak more than 1 MGD. Additional experiments are being conducted to del ineate the col iform problem. The data will be made available in the near future. The District has carried out the Regional Water Quality Control Board's special quarterly exploratory monitoring program on selected organic and metallic pollutants. The results of the last four quarterly samples are presented in Tables 28 through 33. To the best of my knowledge, the information contained herein is true and correct. ~s,[)hM~~ Laboratory Superintendent BSD:pk Attachments POD/BSD/*Anl Dis Rpt INDEX PART I - ANNUAL WASTE DlARACTERISTICS AND LOADING Page No. Figure A - Coliform, TOR, and Chlorine Dose................................. 1 Figure B - Coliform, TSS, and BOD........................................... 2 Figure C - Treatment Plant Flow Schematic - Figure C........................ 3 Total Coliform Comparison of Final Effluent Spiked with Final Effluent- Table A 4 Requirement Compliance Summary, Effluent - Table 1.......................... 5 Annual Average Waste Characteristics and Loading Summary, Effluent - Table 2 6 Annual Average Waste Characteristics and Loading Summary, Influent- Waste (A-001) - Table 3 7 Figure 1 - Monthly Average - Influent Flow MGD.............................. 8 Figure 2 - Influent Total Suspended Solids and BOD Loadings................. 9 Figure 3 - Influent Oil and Grease Loading.................................. 10 Figure 4 - Final Effluent Suspended Solids Concentration and Mass Emission.. 11 Figure 5 - Final Effluent Biochemical Oxygen Demand Concentration and Mass Emission......... 12 Figure 6 - Final Effluent Oil and Grease Concentration and Mass Emission.... 13 Figure 7 - Total Suspended Solids and BOD Removal Efficiency................ 14 Figure 8 - Final Effluent Total Coliform MPN/l00 ml......................... 15 Figure 9 - Final Effluent pH................................................ 16 Final Effluent Fish Toxicity - 96-Hour Bioassay Results - Table 4........... 17 Figure 10 - Final Effluent Fish Toxicity.................................... 18 Annual Average Waste Characteristics and Loading Summary, Effluent Nutrients - Table 5.... 19 Figure 11 - Final Effluent Ammonia and Nitrate-Nitrogen Concentration....... 20 Figure 12 - Final Effluent Organic Nitrogen, Nitrite Nitrogen, and Total Phosphorus Concentration.......... 21 INDEX PART I - ANNUAl WASTE atARACTERISTICS AND LOADING (Conti nued) Page No. Annual Average Waste Characteristics and Loading Summary, Effluent - Trace Metals - Table 6. 22 Annual Average Waste Characteristics and Loading Summary, Effluent - Trace Metals - Table 6A. 23 Annual Average Waste Characteristics and Loadi ng Summary, Effl uent - Trace Metals - Table 7.. 24 An n ua 1 Average Waste Characteristics and Loadi ng Summary, Effluent - Trace Metals - Table 7A. 25 Annual Average Waste Characteristics and Loading Summary, Effluent - Trace Metals - Table 7B. 26 Annual Average Waste Characteristics and Loading Summary, Effluent - Trace Metals - Table 7C. 27 Final Effluent Suspended Solids, Monthly Maximum, Minimum, and Average - Table 8........... 28 Final Effluent BOD, Monthly Maximum, Minimum, and Average - Table 9........................ 29 Final Effluent Oil and Grease, Monthly Maximum, Minimum, and Average - Table 10............ 30 Final Effluent pH, Monthly Maximum, Minimum, and Average - Table 11......... 31 Final Effluent Settleable Matter, Monthly Maximum, Minimum, and Average - Table 12......... 32 Final Effluent Total Coliform, Monthly Maximum, Minimum, and Average - Table 13......... 33 Final Effluent Organic Nitrogen, Monthly Maximum, Minimum, and Average - Table 14.........
