Badum 949 - 644 -3311 or sbadum @city.newport- beach.ca.us SUBJECT: Newport Terrace Landfill Gas Collection and Control System — Completion and Acceptance of Contract No. 3651 and Approval of Amendment No. 3 with SCS Engineers- International, LLC, for Start- up Support Services Relative to Operation and Maintenance of the Completed System Recommendations: 1. Accept the construction work performed and completed by Innovative Construction Solutions, Inc. under Contract No. 3651. 2. Authorize the City Clerk to file a Notice of Completion.. 3. Authorize the City Clerk to release the Labor and Materials bond 35 days after the Notice of Completion has been recorded in accordance with applicable portions of the Civil Code. 4. Release the Faithful Performance Bond one year after City Council acceptance. 5. Approve Amendment No. 3 to the Professional Services Agreement with SCS Engineers - International, LLC for start-up support services relative to the operation and maintenance of the completed landfill gas collection and control system. 6. Approve a Budget Amendment transferring $235,110 from the Environmental Liability Fund to Account No. 7292- C5100735 for the construction of the Newport Terrace Landfill Gas Collection and Control System. Background: In accordance with the terms of the Settlement and License Agreement between the City of Newport Beach and the Newport Condominium Association (NCA), the City has administered the design and construction contracts for the improvements identified as the "Newport Terrace Landfill Gas Collection and Control System ". The firm of SCS Engineers - International, LLC (SCS) from Long Beach, California was hired to prepare plans, specifications, and cost estimates for the scope of work referenced in the Newport Terrace Landfill Gas Collection and Control System — Completion and Acceptance of Contract No. 3651 and Approval of Amendment No. 3 to Professional Services Agreement with SCS Engineers - International, LLC May 27, 2008 Page 2 Settlement Agreement. A Professional Services Agreement with SCS was entered into on December 31, 2006, to assist the City in pre - qualifying construction contractors for competitive bidding on the work and to handle permit processing with regulatory agencies. The not -to- exceed fee amount for this Agreement was $17,000. By June 2007, four contractors had been pre - qualified and the project was ready for bidding. Three of the four contractors submitted bids on June 27, 2007. The low bid of $818,800 was submitted by Innovative Construction Solution, Inc. (ICS). On July 10, 2007, the City Council awarded Contract No. 3651 to ICS for $818,800 and established an amount of $80,000 to cover the cost of unforeseen construction expenses. In addition to awarding the construction contract to ICS, the City Council approved Amendment No. 1 to the December 31, 2006, Professional Services Agreement with SCS in the amount of $83,162 to provide observation and support services during construction of the improvements by ICS. SCS began construction support services in August 2007 and was expected to continue until January 2008. On January 22, 2008, the City Council approved Amendment No. 2 to the Agreement with SCS in the amount of $32,838 for additional and extended construction support services continuing into March 2008. Discussion: ICS has completed the work covered by Contract No. 3651 to the satisfaction of the Public Works Department and the Newport Condominium Association and is recommended for acceptance. The Settlement and License Agreement provides for the City to be responsible for operating and maintaining the landfill gas collection and control system upon completion of its construction. Operation and maintenance costs are to be shared between the City and NCA. The City's Utilities Department is best suited for assuming the responsibility to operate and maintain (O &M) the landfill gas collection and control system. To assist in this responsibility, SCS proposes to prepare an O &M manual and to provide training and consultation to the Utilities Department staff during a "start -up and balancing" period of approximately 60 days. A proposal letter from SCS dated April 22, 2008, describes the services to be provided for a not to exceed amount of $44,925. During this 60 -day period, a determination can be made to have continuing O &M performed by City staff or by a private contractor. A report will be made to the City Council this summer to recommend an operating budget for ongoing maintenance costs for the system. Based on the explanation described above, staff recommends approval of Amendment No. 3 to the Professional Services Agreement with SCS authorizing additional consulting services for a not to exceed amount of $44,925. The proposed Amendment No. 3 is attached for reference. Newport Terrace Landfill Gas Collection and Control System — Completion and Acceptance of Contract No. 3651 and Approval of Amendment No. 3 to Professional Services Agreement with SCS Engineers - International, LLC May 27. 2008 Page 3 Construction Contract Costs: The contract awarded to ICS was based on an amount of $818,800. Progress payments have been made to ISC from a City National Bank escrow account created by $500,000 contributions from each the City and NCA. The final payment amounts under the initial contract total $814,000. In addition, 14 change orders to the contract were approved for a total of $68,840 which is equivalent to an increase of approximately 8.41% over the initial contract amount. Payments to ICS for the initial contract items and the change orders were made from the escrow account in equal amounts from the City and NCA deposits. A summary listing of the 14 contract change orders is enclosed with this report. The initial contract completion date of January 23, 2008, was extended to May 23, 2008, due to the combination of rain days, additional change order work, and waiting for Southern California Edison to install conductors and a new electric meter. The last ten weeks of the contract extension time was the consequence of adding alarm monitoring equipment for communication to the SCADA system in the City Utilities Yard. Overall, ICS performed its work in a timely and responsible manner and staff would recommend them for similar future work. Environmental Review This project is Categorically Exempt from provisions of the California Environmental Quality Act (CEAQ) pursuant to Section 15301, Class 1 of the CEQA Implementing Guidelines. This exemption covers operation, repair, maintenance, minor alteration, etc., of existing structures, facilities, mechanical equipment, etc., involving no expansion of use of that existing at the time of the City's determination. A Notice of Determination has been filed with the Orange County Clerk's Office. Geotechnical / Survey Services: Surveying and construction staking services were provided by a private firm hired by ICS as a part of the construction contract. Construction and Project Management: SCS provided observation and support services during construction as previously described in this staff report. Project management and contract administration on behalf of the Public Works Department was provided by Gail P. Pickart, P.E. under an On -Call Professional Services Agreement approved by the City Council on July 10, 2007.

CA 90806 -6816 www.scsengineers.com SCS ENGINEERS April 22, 2008 File No. 01201221.07 Mr. Gail Pickart, PE City of Newport Beach 3300 Newport Boulevard Newport Beach, CA 92658 -8915 Subject: Proposal to Perform Initial Operations for Newport Terrace Landfill Gas System Modifications Dear Mr. Pickart: This letter constitutes a proposal (revised from original January 31 version sent to Aaron Harp) for SCS Engineers (SCS) to assist the City of Newport Beach in the initial start-up operations of the modified landfill gas (LFG) control system at the Newport Terrace Condominiums. Construction of the system modifications, including new collection piping, a number of new extraction wells, and a completely re- outfitted gas treatment facility, although largely complete, is now expected to be accepted by the city in May. At that point, the contractor will have demonstrated mechanical completion — that the equipment installed is capable of meeting the performance specifications (e.g., flow rates, applied vacuum and discharge pressure, functionality of mechanical and electrical equipment). After the system is accepted by its owner (the City and/or NCA) it will need to be operated, maintained, and monitored. There will be an initial period of relatively intense operations, probably about 60 days, during which the extraction of gas from the landfill (applied vacuum) is balanced to achieve the objectives of the system, i.e., the reduction of methane concentrations in compliance monitoring probes to acceptable levels (below 5% by volume, per state regulations). In addition, a "source test' would be performed pursuant to the SCAQMD Permit, whereby samples of treated gas are collected and analyzed to demonstrate that permit conditions (adsorption of non - methane organic compounds, NMOCs) are being met. After the initial operations the long -term operation, maintenance, and monitoring (OM &M) may begin. This letter presents our proposal for the initial operations. SCS would also be interested in performing the longer term OM &M, and can prepare a proposal for those services at a later date. SCOPE OF WORK During the initial operations, SCS would (in general) do the following: • Perform background (pre- startup) monitoring: methane and pressure in monitoring probes; static pressures and gas concentrations in extraction wells. Offices Nationwide q0 Mr. Gail Pickart April 22, 2008 Page 2 • Initiate system operation with all flow control valves in full open position. • Start up the collection system (blowers). • Monitor flow rates achieved and distribution of applied vacuum throughout wellheads. • Begin closing extraction well control valves to achieve a balance of applied vacuums through the well -field. • Routinely monitor NMOC and sulfur removal in the treatment units. • Perform lab analysis of gas samples from treatment system inlet and outlet (required monthly per conditions of AQMD Permit). • Monitor operation of automated condensate management system (pneumatic sumps, pumps). • Modify condensate trap risers to make them flush with surface. Prepare Operation and Maintenance Manual. This document would compile all available system construction and equipment information and permit conditions, and provide operations and troubleshooting guidance for future system operators. We would provide forms for future reporting of monitoring and operating data. The immediate operational goal will be to reduce methane concentrations in compliance monitoring probes to be below 5% by volume (several probes have had higher methane concentrations in recent months). Once that has been accomplished, a secondary goal will be to reduce the long -term cost of operation by reducing the flow rate of collected gas, and to potentially reduce the hours of operation of the system. (The system is controlled by a 7 -day, 24 -hour timer, allowing less- than -full -time operation.) These measures would hopefully reduce the rate of carbon consumption in the treatment system, and also reduce power consumption. ESTIMATED COST AND SCHEDULE We estimate the following level of effort and cost: Scope Item Estimated Cost Week 1 Two full -time technicians, 3 days at site (each 24 hours @ $80) $3,840 Weeks 2 to 4 One tech, twice weekly, full -day visits (48 hours @ $80) $3,840 Weeks 5 to 9 Twice weekly, half -day visits (50 hours @$80) $4,000 Modification of four condensate risers $2,800 Preparation of O &M Manual, lump sum $7,500 Vehicles and equipment (1 1 days @ $295) $3,245 Mr. Gail Pickart April 22, 2008 Page 3 Note that we have not allowed for costs related to replacement (regeneration) of carbon in the adsorption units, or for the Sulfa -Treat system. We believe it unlikely that this would be needed within the first few months. This also does not address costs such as electrical power, condensate disposal (to the city sewer system) or any other internal city costs. This scope envisions a 2 -month schedule for this initial operations project. If this proposal is acceptable, we assume the City will process the appropriate contracting instrument. We look forward to our continuing relationship with the City of Newport Beach. If you have any questions about this proposal, please call the undersigned. Sincerely, Mark B. Beizer, P ' Senior Vice President SCS ENGINEERS MBB /jml Scope Item Estimated Cost AQMD source test $6,000 Laboratory (gas analyses): 2 months (sulfur and VOC $1,200 analyses) Management and coordination, liaison to LEA, SCAQMD $12,500 Total Estimate $44,925 Note that we have not allowed for costs related to replacement (regeneration) of carbon in the adsorption units, or for the Sulfa -Treat system.
