GeoSyntec <br /> Ms . Polly Kratman Consultants <br /> 7 October 2005 <br /> Page 2 of 8 <br /> Oslo Road , and Rangeline Road in southern Indian River County , Florida . The Class I <br /> landfill includes Segment 1 , Segment 2, and an Infill Area under FDEP Operations <br /> Permit No . 5031 -0128769 -005 . Segment 1 is unlined and was closed in 1990 . <br /> Segment 2 is a lined Class I landfill located east of Segment 1 . The Infill Area is also a <br /> lined Class I landfill located between Segment 1 and Segment 2 that includes a liner <br /> system over the east sideslopes of the previously-closed Segment 1 . <br /> The permitted liner system for the Segment 1 east sideslopes consists of a 60 -mil <br /> thick textured high-density polyethylene (HDPE ) geomembrane overlain by a 24- inch <br /> thick leachate collection system ( LCS ) sand drainage layer. The geomembrane liner for <br /> the Segment 1 east sideslopes was installed as part of the overall Infill Area <br /> construction in 1997 . The LCS sand drainage layer however had to be incrementally <br /> placed during waste placement to ensure stability . The SWDD has the upper third of <br /> the east sideslopes remaining to be covered with sand prior to waste placement . Due to <br /> the difficulty in finding the sand meeting the specifications , SWDD would like to <br /> substitute the 24 - inch thick LCS sand drainage layer with a geocomposite drainage <br /> layer overlain by 24 -inch thick protective soil layer . <br /> PROPOSED SCOPE OF WORK <br /> Task 1 — Project Management/Meetings <br /> Under this task, GeoSyntec will perform project planning and management <br /> responsibilities , such as correspondence with IRC and FDEP , invoice review , project <br /> coordination, and project administration . GeoSyntec has also included budget for <br /> preparation of and attendance at two meetings with SWDD and/or FDEP , as needed . <br /> Task 2 — Minor Modification Permit Application <br /> GeoSyntec will prepare a minor modification permit application (Application) for <br /> the Segment 1 east sideslopes LCS for submittal to FDEP . The Application will <br /> consist of. ( i) FDEP form ( 62 - 701 . 900( 6) ) ; (ii) narrative description of the proposed <br /> revisions to the permitted LCS , including supporting calculations ; ( iii) one to two sheets <br /> of permit drawings showing the limits and cross sections of the proposed LCS ; and ( iv) <br /> technical specifications for the proposed LCS geocomposite drainage layer and <br /> protective soil materials . The Application will be signed and sealed by a registered <br /> professional engineer in the State of Florida . <br /> XLOS 154/XL05094 <br />
