Ruth, General Manager Originator: Ed Torres, Director of Operations and Maintenance SUBJECT: CATIONIC POLYMER CONTRACT UNIT COST AMENDMENT GENERAL MANAGER'S RECOMMENDATION A. Approve Change Order No. 4 to Purchase Order No. 103615-OB, Specification No. C-2008-39513D, with Polydyne, Inc., to add the purchase of emulsion cationic polymer for thickening, for a unit price of $2.738 per active pound delivered, plus applicable sales tax; and for dewatering, for a unit price of $2.881 per active pound delivered, plus applicable sales tax, for an estimated annual contract amount of $2,282,500 for the period July 1, 2012 through June 30, 2013, and subsequent renewal periods; and, B. Approve a 10% annual unit price contingency. SUMMARY Cationic polymer is a critical chemical used in dewatering and secondary solids thickening. The Chemical Sustainability Study recommendation for on-site emergency storage of this chemical has been implemented. Emulsion polymer is more concentrated than solution polymer, and, therefore, provides more polymer storage for every gallon of storage tank capacity. This contract change order with Polydyne will continue to provide not only the daily solution of Mannich polymer for solids processing at Plant No.1 and Plant No.2 dewatering facilities, it will also provide emergency back- up emulsion polymer when regular Mannich polymer deliveries may be unavailable. Capital improvement project No. P2-89, Solids Thickening and Processing Upgrades, will rehabilitate the existing dissolved air flotation thickeners (DAFTs) and polymer system at Plant No. 2. The project will upgrade the existing solution polymer system with equipment to mix and feed emulsion polymer to the DAFTs. During construction of P2-89, a temporary emulsion polymer system will be used to supply the DAFTs with polymer instead of solution polymer provided by the existing polymer system. This contract change order will provide the emulsion polymer for the temporary system. Page 1 of 2 PRIOR COMMITTEE/BOARD ACTIONS May 20, 2009 — Award a contract to Polydyne, Inc., for the Purchase of Liquid Cationic Polymer, Specification No. C-2008-395BD, for a unit price of $1.975 per active pound delivered for Solution Polymer plus applicable sales tax, and $1.85 per active pound delivered for Mannich Polymer plus applicable sales tax, for an estimated annual amount of$2,282,500 for the period July 1, 2009 through June 30, 2010, with four one- year renewal options; and, Approve a 10% annual unit price contingency.

Ruth, General Manager Originator: Nick Arhontes, P.E., Director of Facilities Support Services Engineering Manager: Mark Esquer, P.E., Facilities Support Services SUBJECT: RENEWAL OF SERVICE AGREEMENT FOR CENTRAL GENERATION AUTOMATION/CONTINUOUS EMISSIONS MONITORING SYSTEMS (CEMS), CONTRACT NO. J-79-lA GENERAL MANAGER'S RECOMMENDATION A. Approve renewal of a Sole Source Service Agreement with CEMTEK Environmental for maintenance services of the Central Generation automation/continuous emissions monitoring systems at both Central Generation facilities for a five-year period, for a total amount not to exceed $257,500; and B. Approve a contingency of$25,750 (10%); and C. Approve a budget increase of$66,250 for a total budget of$283,250. SUMMARY Eight Continuous Emission Monitoring Systems, (CEMS) units monitor the exhaust gases of each operational cogeneration engine as required by permits from the South Coast Air Quality Management District, (SCAQMD). The CEMS units and supporting Data Acquisition and Handling Software (DAHS) were procured from CEMTEK Environmental. CEMTEK Environmental has been successfully servicing and maintaining the units, and providing calibration verification reports to SCAQMD for the last three years. As SCAQMD continues to impose more stringent emissions limits, the CEMS and DAHS will require reprograming and calibration to meet the new requirements. Also as part of the upcoming Project J-111, the Central Generation Emissions Controls, each of the remaining seven cogeneration engines will be retrofitted with new emission control equipment similar to the one test unit and will require reprograming of the CEMS and the DAHS. CEMTEK is the sole service provider familiar with the original code and programing language that OCSD requires to support our Modicon programmable logic controllers (PLCs). Staff recommends that the contract for CEMS maintenance of hardware and software and reporting services be renewed with CEMTEK Environmental for an additional five- year term. This will help ensure reliability, regulatory compliance, and continual support services. Page 1 of 2 PRIOR COMMITTEE/BOARD ACTIONS September 2008 — Approval of Contract No. J-79-1A, Continuous Emissions Monitoring System (GEMS). The original maintenance contract was awarded as part of project that installed the CEMS. February 2005 — Approval of Professional Design Services Agreement with Black & Veatch Corporation to prepare plans and specifications for the Central Generation Automation, Project No. J-79-1. ADDITIONAL INFORMATION The current contract will expire on October 31, 2012. If continual monitoring services as required by our permits are nonoperational, the SCAQMD could consider the facility out of compliance and could request a shutdown or impose fines. During Contract No. J-79-1A, the project that installed the CEMS, the District's standard for Modicon PLC equipment was enforced. The Modicon PI-Cs require custom code to be written by CEMTEK that is held to be proprietary to them. Maintenance or capital projects involving changes to the code require their involvement. CEQA N/A BUDGET/ DELEGATION OF AUTHORITY COMPLIANCE This request complies with authority levels of the Sanitation District's Delegation of Authority. This item has been budgeted for FY 2012-13 and FY 2013-14 (section 5, page 11). Date of Approval Contract Amount Contingency 10/24/12 $257,500.00 10 Page 2 of 2 8/5/2012 h b MEMORANDUM 10: Ed Torres Director, Operations &Maintenance FROM- Don van Worst Plant Power Supervisor THROUGFL• Dave Halverson Manager,Division 860 SIVECE Sole Source Justification for Continuous Emission Monitoring system, (CEMS) Maintenance Contract Purchase requisition#77442-ORhas been entered in the amount of$257,500.00 add the details. Bad and OCSD uses eight CEMS units continually monitor the exhaust gases of each engine as required by permits as per the South Coast Air Quality Management Districts, (SCAQMD). The CEMS units and supporting Data Acquisition and Handling Software (DAHS) were procured from CEMTEK Environmental and they have been servicing and maintaining them for the last three years. Beyond monitoring the emissions, the CEMS units send real time data to the urea injection panel that controls the nitrous oxide (NOX) emissions treatment of the engine. This is critical so the right amount of urea is injected to control the NOX but not too much to cause Ammonia slip out the stack to stay in compliance with or SCAQMD permit. The DAHS program will need to be modified for each of the eight CEMS units as the J-111 project comes on line. During the project that installed the CEMS the District's standard for Modicon PLC equipment was enforced even though it is not a normal standard for any of the manufacturers. Justification The purpose of this memorandum is to provide the justification for sole-source procurement of a one year plus four renewals maintenance contract agreement for the Cogeneration CEMS. CEMTEK environmental has been very successful in maintaining the equipment and their support will be critical during the implementation of the emissions control systems in project J-111. The previous attempt by the District to use continuous air monitors was unsuccessful because of high maintenance costs and poor reliability. The positive experience of the present implementation of CEMS is believed to OCSD , P.O.Box B12r , Fauna Valla ,CA 9272"127 , (716)M-W1 be in large part because of the superior maintenance services of the manufacturer, CEMTEK. The Modicon PLC's required custom code to be written by CEMTEK that was held to be proprietary to them. Maintenance or capital projects involving changes to the code will require their involvement. also Recommendation Because CEMTEK is the manufacturer of this specialized item and the supporting software they are uniquely qualified to maintain it. They have been successfully providing the service for three years. Other vendors would require difficult training to learn the CEMTEK equipment and would have to hire programing staff to interact with the Modicon PLC's. For these reasons and the critical need to properly maintain these systems for regulatory compliance , district staff recommends sole-sourcing the CEMS maintenance contract to CEMTEK Environmental.
