notification of, and documentation to regulatory agencies . Indian River County shall be immediately notified of any spill . ARTICLE II —DEWATERING 1 . CONTRACTOR shall process Indian River County sludge generated at Indian River County- owned wastewater treatment facilities . Indian River County sludge is anticipated to total approximately 30 million gallons per year with a feed percent solids range 2 percent to 3 percent . This figure is an estimate , and the actual Indian River County sludge , which is a mixture of septage and grease , generated may vary . The feed percent solids range is estimated and may increase or decrease depending on the operations of the Indian River County- owned wastewater treatment facilities . The CONTRACTOR shall be responsible for accepting and dewatering the sludge regardless of solids percentage . NOTE : CONTRACTOR shall assume all responsibility for the proper disposition of all Indian River County sludge once it is accepted by the CONTRACTOR . 2 . CONTRACTOR shall mobilized within 7 days of the Notice to Proceed . The contract start dated is subject to construction completion of the new Indian River County Biosolids Dewatering Facility . 3 .

CONTRACTOR shall utilize centrifuge equipment for the dewatering operations . 5 . CONTRACTOR shall dewater Indian River County sludge to a minimum Total Solids Percent of 17 percent solids , and guarantee that the sludge will pass a paint filter test upon final disposition . 6 . CONTRACTOR shall perform daily Total Solids Percent testing and submit the test reports to Indian River County on a weekly basis . Grab samples of the sludge feed, centrate , and cake shall be taken each hour for each operating centrifuge . Each grab sample shall be combined in equal portions into daily composites for the sludge feed , centrate and cake . Each composite sample shall be analyzed for Total Solids Percent. These samples are in addition to any other parameters that may be required by the permit . The CONTRACTOR shall provide an operational log sheet, which will be provided by Indian River County , that shows the time and operating conditions at the time that each grab sample is taken . The operating conditions on the log shall include but not be limited to centrifuge speed, drive amps , torque , feed rate , totalizer flow number, polymer rate , polymer setting , holding tank feeding centrifuge , holding tank level ) . 7 . In the event the Total Solids Percent test shows that the minimum Total Solids Percent ( 17 percent) was not met, payment for that day will not be approved . 8 . Indian River County sludge volume calculations shall be based on dry tons produced , or other mutually acceptable methods , yielding a net price per dry ton produced . Page 18 of 47
