Mr . Hirnanshu Mehta, P . E . <br /> 9 April 2011 <br /> Page 2 <br /> PROJECT BACKGROUND <br /> The IRCL facility is located in southern Indian River County , east of Interstate 95 , south of Oslo <br /> Road , and west of Rangeline Road in Vero Beach , Florida . The SWDD administers the <br /> management and operation of the Class I landfill at the IRCL facility . The Class I Landfill <br /> includes Segment 1 , Segment 2 , and an Infill Area located between Segment 1 and Segment 2 . <br /> Segment 1 is approximately 20 acres, unlined , and was initially closed in 1990 with a cover <br /> system that included 8 - to 12 - in . thick compacted clay cap . Segment 2 , which is approximately <br /> 38 acres in total footprint, has a 60 -mil thick high -density polyethylene (HDPE) geomembrane <br /> single liner . The Infill Area has : (i) a single composite liner comprised of a 60 -mil thick HDPE <br /> geomembrane placed on top of 2 - ft thick compacted clay liner over a 5 -acre area between <br /> Segment 1 and Segment 2 ; and (ii) a 60 - mil thick textured HDPE geomembrane single liner over <br /> the 7 . 5 acres of the eastern side slopes of the closed Segment 1 landfill . <br /> In October 2009, the SWDD completed the construction of the vertical expansion and partial <br /> closure of the Class I Landfill . The vertical expansion extends the life of the Class I landfill until <br /> January 2013 , based on current and projected waste acceptance rates . In order to meet the <br /> requirements of the IRC 2030 Comprehensive Plan, SWDD needs to construct another cell to <br /> provide the County with a minimum of five years of disposal capacity at the IRCL facility . <br /> The Segment 3 Expansion is comprised of two previously permitted landfill cells including a 32 - <br /> acre C &D disposal facility, Cell 2 , located east of Segment 2 that was permitted by the Florida <br /> Department of Environmental Protection (FDEP) on 15 June 2007 and a 38 -acre Class I landfill , <br /> Segment 3 , located east of the sedimentation pond and south of Cell 2 , that was also permitted by <br /> FDEP on 25 August 2008 . Because the SWDD has discontinued the practice of separate <br /> disposal of C &D debris in an unlined disposal facility, but rather for co - disposal of C &D debris <br /> in a Class I landfill comingled with municipal solid waste (MSW) , on behalf of SWDD, <br /> Geosyntec submitted to FDEP on March 17 , 2010 a combined 5 -year renewal , and construct and <br /> operate permit application for the Class I Landfill . The permit application also included a design <br /> to convert the 32 -acre Cell 2 C &D disposal area to a Class I Landfill integrated with <br />the <br /> previously permitted Segment 3 as well as a lateral expansion east of Segment 2 . On 9 <br /> December 2010, the FDEP issued the Intent to Issue the Permit for the renewal and expansion of <br /> the Class I Landfill in accordance with the permit application prepared by Geosyntec . SWDD <br /> published the FDEP ' s notice of intent in the Indian River Press Journal on 16 December 2010 , <br /> and Geosyntec submitted a letter on SWDD ' s behalf to FDEP requesting changes to the Draft <br /> Permit on 16 February 2011 . The FDEP responded to this request on 11 March 2011 and issued <br /> the Final Permit on 18 March 2011 . <br /> JL10086 Final <br /> ( 11 inners Sscic ntisis i inllov.nears <br />
