Zeolite AnammoxCentral Contra Costa Sanitary District ' BOARD OF DIRECTORS POSITION PAPER Board Meeting Date: October 2, 2014 subject: AUTHORIZE THE GENERAL MANAGER TO REVISE AGREEMENT 041599 WITH COLLISON ENGINEERING FOR PROFESSIONAL ENGINEERING SERVICES BY INCREASING THE COST CEILING FROM $95,000 TO $225,000 TO INCLUDE THE SURFACE AREA METHOD WITH THE ZEOLITE - ANAMMOX PILOT PLANT STUDY AND EXTEND THE AERATED METHODS BY 12 ADDITIONAL MONTHS Submitted By: Initiating Dept. /Div.: Randy Schmidt, PE, Senior Engineer Operations Department REVIEWED AND RECOMMENDED FOR BOARD ACTION: Jean -Marc Petit, Acting Deputy General Manager Edgar Lopez, Provisional Capital Projects Division Manager Roger S. Bailey General Manager ISSUE: Board authorization is required for the General Manager to execute a professional engineering services agreement when aggregated revisions are expected to total more than $100,000. Agreement 041599 with Collison Engineering for $95,000 to construct and operate the Phase 1 of the Zeolite - Anammox Pilot Plant was signed on June 12, 2014. The Phase 1 of the Zeolite - Anammox Pilot Plant consists of building and operating blown aeration and re- circulating trickling filter aeration units mounted in an insulated semi - trailer processing approximately 3,000 gallons per day of final effluent for a period of 12 months, June 2014 to June 2015. There is a third variation of the process called the surface area method which is a non - aerated method with no energy demand. This method could potentially be used as a polishing step for removal of low levels of ammonia. Additional funds are needed to build the surface area pilot plant on a second semi - trailer, operate the surface area pilot plant for 24 months, and operate the aerated pilot plant for an additional 12 months. These additional funds total $130,000. The aggregate amount of the revised contract would therefore be $225,000. RECOMMENDATION: Authorize the General Manager to revise Agreement 041599 with Collison Engineering for professional engineering services by increasing the cost ceiling from $95,000 to $225,000 to add the surface area method to the Zeolite- Anammox Pilot Plant Study and extend the aerated methods by 12 additional months. FINANCIAL IMPACTS: The total estimated cost for Phase 1 of the Zeolite- Anammox Pilot Plant Study, including the Surface Area Method, is $250,000. Adequate funds are available in the Treatment Plant Program of the Fiscal Year (FY) 2014 -15 Capital Improvement Budget (CIB) to cover this contract.

However, doing so would prevent the investigation of the surface area method for ammonia removal as well as limit the time that the aeration method could be tested. BACKGROUND: Robert Collison, PhD, through his company, Collison Engineering, is the researcher doing scale -up on the unique Zeolite - Anammox process to reduce ammonia from a final effluent single vessel, two -stage bio- reactor. Dr. Collison has a pending patent on the Zeolite - Anammox process and is the only local source of Anammox bacteria to convert ammonia to nitrogen and water. Having just completed a pilot test at Union Sanitary District and the Oro Loma Wastewater Treatment Plant, he is now ready to pilot test another pilot plant at CCCSD. This project has been identified and submitted to the Regional Water Quality Control Board (RWQCB) in the 2013 Nutrient Visioning Plan as one of the preferred cutting - edge nitrogen removal technologies to pilot test for meeting future ammonia limits in final effluent and recycled water. In addition, the proposed pilot plant ties directly to two of the goals specified in the draft 2014 Strategic Plan: Goal No. 1 includes an initiative to explore technologies that use less energy and produce less greenhouse gases, and Goal No.4 states the District's strategy to be a leader in the wastewater industry by embracing innovation. This Phase 1 pilot plant would collect data on the blown aeration, trickling filter aeration, and surface area methods of ammonia removal for a larger Phase 2 pilot plant, at approximately 100,000 gallons per day. It would demonstrate process and site - specific viability, generate design data and parameters, determine site - specific nutrient removal performance, and estimate capital and operational expenses for a full -scale treatment for the District. CCCSD entered into an agreement with Collison Engineering in June of 2014 to pilot test the blown aeration and trickling filter aeration methods of zeolite - anammox utilization to removal ammonia. The challenge with either active aeration method is how to meet the energy demand. There is an additional zeolite - anammox method called "surface area method," which utilizes oxygen transfer across the water -air interface over a bed of submerged zeolite. There is no energy demand for aeration. The goal of the addition of the surface area method as polishing tanks is to determine the surface area requirement and optimize Page 3 of 3 POSITION PAPER Board Meeting Date: October 2, 2014 Subject: AUTHORIZE THE GENERAL MANAGER TO REVISE AGREEMENT 041599 WITH COLLISON ENGINEERING FOR PROFESSIONAL ENGINEERING SERVICES BY INCREASING THE COST CEILING FROM $95,000 TO $225,000 TO INCLUDE THE SURFACE AREA METHOD WITH THE ZEOLITE ANAMMOX PILOT PLANT STUDY AND EXTEND THE AERATED METHODS BY 12 ADDITIONAL MONTHS the energy usage in the hope of reducing aeration - related cost in full -scale treatment. Additional funds are needed to build the surface area pilot plant on a second semi- trailer, operate the surface area pilot plant for 24 months, and operate the aerated pilot plant for an additional 12 months. These additional funds total $130,000. The aggregate amount of the revised contract would therefore be $225,000. The total cost of Phase 1 of the Study is estimated at $250,000, which includes $225,000 for the Collison Engineering Contract and $25,000 for purchasing equipment needed for the pilot project. The Zeolite - Anammox Pilot Plant Study is included as part of DP 7315 - Plant of the Future Roadmap project in the FY 2014 -15 CIB on page TP -10. Staff has conducted a cash -flow analysis of the Treatment Plant Program budget and concluded that adequate funds are available for this pilot study, as shown below: FY 2014 -15 Treatment Plant Program Allocation Budget: Authorized Program Allocations $ 4,261,700 Previous FY 14 -15 Allocations to date $ 0 This Allocation for DP 7315 $ 155.000 Remaining Authorization Budget $ 4,106,700 COMMITTEE RECOMMENDATION: The Engineering and Operations Committee reviewed this matter at its September 22, 2014 meeting and recommended that...
