Mr. Himanshu H. Mehta, P.E. 11 July 2007 Page 4 Task 2 : Hvdroueological and Geotechnical Site Investigations The site investigation will be performed in accordance with Rule 62-701 .410, FAC to establish geotechnical, geological and hydrogeological characteristics of the proposed 33 acre of Cell 2 area as Class I landfill expansion. The purpose of the investigation is to obtain the site-specific data necessary to address the elements of Rule 62-701 . 410, FAC, and also to support the design, permitting and groundwater monitoring requirements for the proposed Class I landfill lateral Y expansion. The proposed scope of work for Task 2 assumes that sufficient hydrogeological and geotechnical investigations have been performed as part of the design and permitting of the Cell 2 C&D disposal facility. Geosyntec will review previous geologic, hydrogeological and geotechnical investigation reports and documents completed for the design and permitting of C&D Cell 2 and compare them with the corresponding data used for the design and permitting of Class I Segment 3 landfill expansion, to identify additional information needs. Existing site hydrogeological and geotechnical information collected from previous investigations and data collected during the Class I Segment 3 and C&D Cell 2 investigations will be compiled in a relational electronic data base to facilitate data evaluation. Geosyntec will revise the Hydrogeological and Geotechnical Investigation Report (report) for the Class I Segment 3 landfill application to include the results of the additional data from the C&D Cell 2 investigations . The report will address the following hydrogeological investigation requirements of Rule 62-701 .410( 1 ), FAC: • a description of the landfill site geology and hydrogeology and its relationship to the local and regional hydrogeologic patterns; • an inventory of all public and private water wells within one-mile radius of the proposed landfill expansion; and • a map showing the location of all potable wells within 500 feet of the landfill, and locations of all wells serving community water supplies within 1 ,000 feet of the proposed landfill expansion. The report will also address geotechnical investigation requirements of Rule 62-710.410(2), FAC, including the following: • interpretation of the subsurface conditions including soil stratigraphy and ground water table conditions; XL0609MAniendment to Class 1 landfill Design Work Order.doc engineers I scientists I innovators
