The 1998 Waste Discharge Requirements (RWQCB Order No. 98-54) issued by the Regional Water Quality Control Board require that the City take measures to increase the plant's ability to remove nitrogen from its effluent. Among the requirements set by the RWQCB is the preparation and submittal of a report discussing how and to what extent the City can improve nitrogen removal, on an interim basis, using minor modifications and operational changes to the existing plant. This report has been filed with and accepted by the RWQCB. As a result, the RWQCB has asked that some of the changes discussed in the report be implemented and their results evaluated. This agreement will provide for the ongoing engineering and operational assistance needed to comply with the RWQCBs requirements and to maximize the nitrogen removal efficiency of the existing facilities. Another requirement of the 1998 Waste Discharge Requirements (WDR) is that the City must submit a plan and schedule indicating how and when the City proposes to comply with the requirement to reduce the total inorganic nitrogen (TIN) content of its effluent to less than 10 mg/L The interim TIN limit is 15 mg/L, and the City has been in compliance. This plan and schedule must be submitted within 30 days of May 31, 1999. It should be noted that the current WDR requires that the City comply with the 10 mg/L TIN limit by May 31, 2001. The above noted plan and schedule will be based on a study and report prepared to evaluate alternative methods for nitrogen removal and the timing and costs of their implementation. Preparation of the report, plan and schedule will be provided under this agreement. One potential means of removing nitrogen is to operate the existing percolation ponds (effluent disposal ponds)east of Alabama Street to maximize natural removal in the underlying soil column. Removal may already be occurring in the soil, but the amount is not known. In order to explore this potentially low cost method of nitrogen removal, a field investigation and demonstration, following a protocol worked out jointly with the RWQCB, is needed. The investigation should provide operational criteria and a removal efficiency acceptable to e RWQCB. Authorization f the riz to assist the City with the investigation will be covered by this agreement. There are various other areas involved with nitrogen removal and permit compliance where operational assistance and design services are, and from time to time will be,required by the City in order to address changing regulations, evaluate new technologies, up grade systems, and help with regulatory and operational difficulties. This agreement is intended to provide for such on going services to the City. S:,CONTRAC'r,Redlart&,F-valAgr.

Intermittent spreading and percolation through a soil column will remove some nitrogen from the spread effluent, and the City may be able to benefit from this removal in meeting its regulatory discharge limitations for nitrogen. If the ponds can be operated to reliably remove some of the effluent nitrogen, the RWQCB may allow a credit such that the requirement for in-plant removal can be reduced. A study, based on a protocol approved by the RWQCB, will be required in order to determine acceptable removal efficiencies and operating parameters for the ponds. The study is meant to demonstrate the effectiveness of percolation to remove effluent nitrogen rather than to be a research project. Scope of Services To assist the City in completing the study, developing protocol and methodology, providing assistance and advice during the study, interpreting the results, documenting the work, and obtaining regulatory acceptance, as outlined in the following tasks, will be necessary. The study covered by this scope is meant to evaluate removal of nitrogen in the soil column under and immediately adjacent to the existing ponds and to determine a fill and drain cycle and other operating criteria consistent with good nitrogen removal. At the option of the City, the scope can be expanded to evaluate other topics such as removal mechanisms, removal of other constituents, area hydrology and other subjects, the need for which may arise during the study. Task 1. Meet with the City to discuss the project and collect available information. Task 2. Develop a tentative protocol for the study and meet with the RWQCB to discuss and finalize it. The protocol will include locations and types of monitoring and sampling systems, sampling schedules, analytical methods, report format and content, and timing. It should be recognized that the need to modify parts the protocol should be expected as the study progresses. Task 3. Assist the City by recommending the selection, location, design, installation, and operation of sampling and monitoring systems. S:\C0NTRAC'RRed1arW%NitT02.v,pd A-1 Task 4. Provide a monthly overview of operation and findings from the project. Meet with the City to discuss the findings and any apparent need to modify the protocol. Task 5. Prepare quarterly reports summarizing the findings for the period for the City to file with the RWQCB. Task 6. Prepare a final report summarizing the work, giving and interpreting findings, and recommending criteria for operating the ponds as a nitrogen removal process. Task 7. After filing the final report, meet with the City and the RWQCB to discuss modifications to the City's waste discharge requirements and any benefits of continuing the monitoring program. Services Provided by City The City will provide the following: 1 All construction including that of monitoring wells, sampling stations, lysimeters, and access roads. 2. Geotechnical investigations, if they become necessary, including hydrogeological studies. 3. Sampling and laboratory analyzes of samples. 4. Operation of treatment, pumping, water transmission and flow control systems and the ponds. 5.
