EXHIBIT 1 <br /> SCOPE OF WORK <br /> INDIAN RIVER RCOUNTY <br /> BIOSOLIDS DEWATERING FACILITY AT INDIAN RIVER COUNTY LANDFILL <br /> ADMENDMENT NO. 2 - ADDITIONAL DESIGN AND PERMITTING SERVICES <br /> BACKGROUND <br /> Indian River County (IRC) Utility Services Department currently operates a centralized <br /> dewatering facility located at the Central Region Wastewater Treatment Plant. The close <br /> proximity of the existing dewatering facility to neighboring developments led IRC to explore <br /> moving the operation to the IRC Landfill. The IRC Landfill is the current recipient of the sludge <br /> dewatered at the existing facility. Given the age of the existing dewatering facility' s equipment, <br /> a new facility was proposed to be located at the landfill. The new Biosolids Dewatering Facility <br /> (BDF) would be designed to have the necessary sludge receiving, pumping, and tankage to <br /> meet IRC's needs as well as the needs of the private grease and septage haulers in IRC. The <br /> facility would be designed for a twenty year equipment life cycle. Dewatering equipment <br /> would be provided by a private contract operator with a five year operating contract with <br /> renewal options in accordance with IRC policy. <br /> The current design of the BDF places the facility on a 180-foot wide strip of landfill property <br /> between the permitted construction and demolition (C&D) debris cell and the Class I cell <br /> located to the west. Siting of the BDF in its present location does not allow use of the infill <br /> volume between the two landfill cells. In August 2007, IRC considered the potential use and <br /> value of the infill volume between the two cells and requested CDM to perform a conceptual <br /> level evaluation of the area. The evaluation indicated that use of the infill volume for disposal <br /> of C&D debris, could result in a potential $44.3 million of future incoming revenue to IRC and <br /> could extend the landfill useful life by approximately 13 additional years. <br /> Based on the above, IRC staff determined that the potential beneficial use of the infill volume <br /> between the two cells warranted the relocation of the BDF to an alternate location within the <br /> landfill property boundary. With relocation of the BDF, the infill volume between the C&D <br /> debris cell and the Class I landfill cell will remain available for future use. The alternate <br /> location, the area of second lateral expansion of the existing C&D debris landfill, located south <br /> of the administration area and along the 74thAvenue, was selected based on discussions and <br /> review by CDM and IRC of various potential sites within the landfill property. <br /> Revision of the current design to relocate the BDF to the selected alternate location will <br /> maintain the current internal layout and footprint of the facility as much as is practically <br /> feasible, but will require surveying and subsurface investigation of the new facility location, <br /> additional permitting services, and additional engineering services related to final design. <br /> The intent of this Amendment is to provide additional funding for the upper limit of Tasks 1, 2, <br /> and 3 . <br /> 1 ieia 7 c <br />
