z Landfill staff has previously evaluated pumping the leachate. The costs were prohibitive because of the distance to the nearest OWASA manhole. The Town of Chapel Hill will soon be installing a sewer manhole at the northeast corner of Eubanks Road and Millhouse Road to serve the new Chapel Hill Operations Center on Millhouse Road, This provides a new opportunity for a landfill sewer connection, Installation of a landfill pump station/gravity sewer will eliminate the requirement of a tank truck to haul the leachate to an OWASA manhole or the treatment plant. Staff is also examining the feasibility of connecting the new Solid Waste Operations Center to the landfill sewer line, At their April 12, 2005 meeting, the Board of Commissioners indicated a preference to have the new building to be connected to sewer rather than to rely on an on-site septic system or alternative treatment system. Therefore, the engineer has been asked to provide an alternative design scope of work and fee estimate that would include this additional design element, The agreement will be modified to allow Orange County the option to also include the design of a sewer extension to the Solid Waste Operations Center parcel, should the Board make such a determination. Request for Proposals were sent to Philip Post & Associates, Ballentine Associates, PA, Mitchell Westendorf, PA, and The .lohn McAdams Company, Inc., all who have done similar work for OWASA, Philip Past & Associates submitted the only proposah FINANCIAL IMPACT: Funds for the engineering project are available in the FY2004-05 Solid Waste Department budget, Engineering fees for the landfill leachate design scope are estimated at $65,475. If the alternative Solid Waste Operations Center sewer extension were included, the total design cost would increase by $11,125 for a total of $76,600. These two estimates are a guaranteed maximum, An estimated additional $20,400 in direct expenses is also anticipated. RECOMMENDATION(S): The Manager recommends that the Board approve the Agreement with Phillip Past & Associates, and authorize the Chair to sign the Agreement, subject to final review by staff and the County Attorney.
