Mr. Himanshu H . Mehta, P . E . 8 March 2011 Page 3 Phase 2 — Meetings/Response to Comments Under this task, Geosyntec has included budget for preparation and attendance (by two Geosyntec personnel) at one meeting with IRC . The budget includes 20 hours for preparation for and attendance at the meeting for Mr. Jim Langenbach and 12 hours for these activities for Ms . Nandra Weeks . Under this task, Geosyntec will also provide a response to FDEP comments dated 28 January 2011 . Phase 3 — Implement FDEP-Required Activities Under this task, Geosyntec will implement the activities outlined in the 28 January 2011 letter from FDEP . These activities will include : (i) preparation of a RAPM Addendum No . 2 to propose additional bioremediation remedial activities in the vicinity of GR-MW30 ; ( ii ) installation , development, surveying and sampling of up to six requested additional monitoring wells in the vicinity of GR-MW17 and GR-MW30 ; and ( iii) reporting . It is anticipated that the RAPM Addendum No . 2 will also outline a plan to re -dose the existing biobarriers at the site . Installation of the monitoring wells requested by FDEP may require brush clearing to provide access to the area in the vicinity of GR-MW17 , as well as potential coordination and/or approval for access onto the airport property . (Note : Budget has not been included for additional bioremediation injection activities which will be proposed in the RAPM or the re- dosing of the biobarrier) . Phase 4 — Field Activities Under this task, Geosyntec will perform all field activities related to the plume groundwater monitoring, as discussed herein . The field activities will include field preparation , groundwater sampling, and water level measurements . Field preparation activities will include scheduling and staffing, subcontracting, field equipment preparation , and notifying FDEP of the field schedule . In addition, we will coordinate with Environmental Conservation Laboratories , Inc . (ENCO) , the analytical laboratory contracted with IRC , regarding laboratory analyses required by FDEP . Geosyntec will perform the groundwater sampling activities associated with the CVOC plume monitoring wells . Groundwater sampling activities will be executed using a two -person sampling crew and will be performed in general accordance with the FDEP Standard Operating Procedures ( SOPS) . The proposed annual field event will be conducted in the summer of 2011 (tentatively in June) and will include sampling of 56 monitoring wells . The proposed semi - annual field event will be conducted in winter 2011 (tentatively in December) and will include sampling of 23 monitoring wells . The annual and semi -annual field events are budgeted to be completed with a two -person team within approximately five days and three days, respectively . Consistent field documentation and field protocols will be utilized to develop reliable data to support the natural attenuation of the groundwater plume . It is anticipated that purge water (IDW) will be treated in the existing air stripper sump and discharged to the sanitary sewer following treatment . No costs are included herein for IDW disposal .
