Up to 500 wet tons of the biosolids will be Class A and have a moisture content of about 14%. The remaining biosolids are Class B with a moisture content of about 50%. Upon loading into trucks, the volume may be expected to expand by about 10%. The biosolids will be stockpiled on asphalt-paved drying beds at the Water Pollution Control Plant. There is good access and egress from the biosolids storage area. There is a sand drainage area within the mid-section of each bed. This drainage area must not be driven upon or crossed with heavy equipment. The beds or City property must not be damaged in any way. The Laboratory analysis will be made available upon request. These biosolids will meet EPA Part 503 Biosolids Rule for CLASS A or CLASS B BIOSOLIDS. The stockpiled biosolids might have areas within the stockpile that are hot, smoking and/ or smoldering. All loads must be covered; therefore, the Contractor will be responsible for cooling any hot spots to prevent possible damage to covers, tarps, etc. Disposal options must be approved by the Contract Administrator for the City of San Leandro and positively confirmed. If the biosolids are to be spread on land, they must be applied at appropriate agronomic rates and the Contractor must obtain the necessary certifications and permits. The City will provide analysis for the material. The Contractor must select a disposal option and provide verification of that option prior to submitting their bid to the City. It is the Contractor’s responsibility to select an option that conforms to applicable Federal, State, and local criteria for this particular material. Copies of all transportation and disposal documents are required by the City of San Leandro. The Project and/or other City employees may request to witness the placement of biosolids for land application. Biosolids Removal Strategy The Contractor shall load, haul, and legally dispose of the biosolids. The biosolids may be hauled up to four times over the term of the contract. Contractor shall pay for all equipment rental, permits, receiving facility fees, tariffs, and personnel costs incurred in legally disposing of the biosolids. Any negligence on the Contractor’s part shall be rectified by the Contractor. The contract is on a per ton basis. Tonnage may be determined by field- site scales supplied by the contractor; or by an off-site certified scale approved by the Contract Administrator prior to use, with documentation of each load required to be submitted to the Contract Administrator. Dust control shall be the responsibility of the Contractor during the loading and hauling operation. Plant effluent water (No. 3 water) is available for use by the Contractor if the Contractor wishes to lightly water down the loaded material to assist in dust control. Said practice shall be performed after each load weight has been determined. All trucks shall be tarped. Documentation The Contractor shall supply copies of transportation manifests for each load. The Contractor is solely responsible for cleanup of any spills on public or private streets or properties. The costs of any fines from improper management or accidental spillage shall be borne by the Contractor in its entirety. LIQUIDATED DAMAGES: Failure to start and complete all work specified within the time allowed shall constitute material breach of contract. The "time allowed" will be calculated from the date of the Notice to Proceed through the end date indicated by the City in the Non-Professional Services Agreement. Failure of successful Bidder to complete the work or deliver the goods within the time allowed will result in damages, and for each consecutive day in excess, the contractor shall pay to the City the sum of $250 per calendar day.
