c. Daily Operations. All solid waste accepted at the landfill sites shall be thoroughly spread and compacted by repeated passage of equipment of sufficient weight and capacity to meet the requirements of the operational plan and permit. The Contractor is required to achieve a minimum density of 1400 lbs./cubic yard for the solid waste fraction. This does not include the borrow used for cover. Monthly estimates of cover used will be supplied to the Owner. The unit weight of soil used as cover will be assumed to be 2700 lbs./cubic yard. The density will be based on an annual survey performed in July of each year. If the Contractor fails to meet the historical density of 1400 lbs./cubic yard, a penalty will be assessed at the end of each fiscal year according to the following schedule. Density Range Mon 1350 to 1399 lb/CY 0.50 1300 to 1349 lb/CY 1.00 1250 to 12991b/CY 1.50 1200 to 1249 lb/CY 2.00 The number of tons used in the penalty calculations will be the tonnage placed in the Class I landfill during the preceding July 1 to June 30 period. Volume calculations will be performed by the Engineer, and copies of the previous and present year's survey plus the calculations will be provided to the Contractor by September 1 of each calendar year. The first lift of waste shall be compacted in accordance with the operations to reach a maximum density of 1000 LBS/CY. The first year's density requirements will be adjusted according to the total tonnage of waste placed and the percentage of waste represented by the first lift. Beginning the second full year of operation the density of 1400 LBS/CY will be required. No bonus will be given for densities exceeding 1400 LBS/CY. The Contractor is responsible for obtaining his own borrow material from offsite or onsite sources for maintenance and/or for use as cover material. All soil materials available at the existing landfill site within designated future borrow or future stormwater lake areas may be available for excavation and use by the Contractor for a fee which may be negotiated with the Owner. d. Closure of Class I Landfill. Upon the completion of disposal operations to final contours, the top surface will be contoured and finished in accordance with the permit as it exists at the time of this Contract. Future final closure phases (after the initial closure of Segment II to elevation 55 NGVD) will be built as a new construction project and may be competitively bid at the County's option.
