CITY OF COLTON AGENDA REPORT For Council Meeting of September 4, 1990 TO: Honorable Mayor and City Council FROM: John C. Hutton, Director of Public Works SUBJECT: Proposals to Remove Sludge Material from Date: August 30, 1990 the Sewer Treatment Plant nnrurtxv TMn . The City's Sewer Treatment Plant generates approximately 5 tons of solid waste (sludge) material per day. This material is dried and stored at the plant and eventually must be removed in order to provide room for additional material. STATEMENT OF PROBLEM: The State Regional Quality Control Board allows for only so much material to be stored onsite by permit and then it is required to be removed to an acceptable location, which there are very few of. Landfills are no longer a viable disposal point for sludge due to the cost per ton to dispose, the stringent regulations regarding contents within the sludge, and most of all available space at landfills, which are becoming fewer. ALTERNATIVES: Two proposals have been received, one just prior to the last Council meeting. The late proposal submitted by L. Curti Company did not allow for sufficient time for review by staff in order to provide a recommendation to Council at their last meeting when Council was considering the proposal from Varela Industries. Both proposals have now been reviewed by both staff and the City's consulting engineer, Krieger and Stewart (report attached). FINANCIAL IMPACT: The removal of the sludge from the Sewer Treatment Plant is a funded maintenance item within the budget. The estimated volume of material to be removed form the Sewer Treatment Plant is 3200 cubic yards (equivalent to approximately 2800 tons). Based upon the approximate tonnage to be removed, and the unit price per ton submitted in the two proposals (considering tonnage increases daily) the following would reflect cost for removal.
