These two items include updating the treatment evaluation and alternatives based on the final diluent permit and projected nutrient requirements, and increasing the scope of the infiltration/inllow study. A breakdown of the additional work items and estimated cost are as follows: 1. Facilities Plan Completion A. Update treatment evaluation based on Final Efllucnt limits and projected nutrient requirements. 1. Update cost for alternative plan if in Draft Facilities Plan. 2. Review alternative systems identified in the CH,M Eva]uation including Sequencing Batch Reactor, and conventional activated sludge. B. Present alternatives to Moscow staff and Public Works Committee. C. Prepare Draft Facilities Plan, review with DEQ and City. conduct Public Hearing. D. Prepare Final Facilities Plan including comments from Moscow. Public and DEQ. Total Estimated Cost $7,500 $500 $2,000 $2,000 $12,000 ---PAGE BREAK--- Gregg N. Teasdale Page 2 March 3, 1995 2. Additional lnfiltration/In!1ow Work A. Outline 1/I program, goals, data needs, technique, previous reports, treatment vs. correction. B. Review ll/SSES program with the City staff, !low meter evaluation regarding calibration, and set up procedure, event monitoring and baseline monitoring. C. Identify baseline !1ow monitoring locations and assist the City in installing initial !low meters. Coordinate rental and installation of additional !low monitoring equipment. D. Identify successive location for tlow meter installation. Periodically check manhole water depth visually from the surface during rainfall event. E. Evaluate !low meter data, and determine baseline flows and impact of storm events. Download information and plot. F. Prepare annual summary of data, recommend future monitoring location, and corrective action program. Review with staff and Public Works Committee. Total Estimated Cost $360 $430 $1,100 $4,360 $3,610 $5,100 $14,960 Excessive infiltration/intlow was identified in the draft Facilities Plan triggering the need for more extensive I/I investigation and tlow monitoring. See enclosed hydrographs over the last few years from the wastewater treatment plant. The only III work done under the original scope of work was some smoke testing in the University and downtown areas. While some problems were found and identified with the smoke testing they are not deemed significant enough to account for a major portion of the I/I problem. ---PAGE BREAK--- Gregg N Teasdale Page 3 March 3, 1995 It will probably take two years to determine the extent of the problem and develop a correction plan. This study will identify areas where Ill can he corrected that could offset up to $2,000,000 in treatment plant oversizing. The main benefit would he to reduce the peak tlows which reach four times the average daily !low and severely impact treatment plant performance. These peak tlows may cause partial bypass of untreated sewage to Paradise Creek, causing NPDES permit violations. Please review our proposed addition to the original scope of work for Moscow's grant and let us know if you will support this additional work and subsequent grant increase request. If you have any questions, please do not hesitate to call. Very truly yours, KIMBALL ENGINEERING, P.A.
