The FDEP correspondence was generated based upon a review of Geosyntec ' s 21 September 2009 report, Site Assessment Report; North RO Plant, Facility 99600729 . Based upon a review of the Site Assessment Report ( SAR) , FDEP approved the Natural Attenuation (NAM ) Plan proposed in the September 2009 SAR for the above reference Site with the following specific conditions : • The NAM Plan shall include "ells MW01, A4-W02, MW03, MW059 MW06, PZ10, PZ19, PZ20, and PZ22 . • Groundivater monitoring shall be completed on a quarterly basis 17) i1h quarters being January through March, April through June, .July through September and October through December. • If sodium concentrations increase above the current concentration of 213 milligrams per liter reported in the groundwater samples fi°om well MW06 then the Department shall require additional assessment activities near ivell MW06 as needed to define the extent of horizontal contamination.

Terry Southard 24 March 2010 Page 2 • The Manager of the Indian River Counly Department that resides on the property to the west and north of the Indian River Count) North RO facility must be notified in writing that the sodium plume has been partially defined and may extend onto the property west of the site and that groundwater monitoring with specific conditions has been approved instead of further assessment at this time . In addition, the Indian River County Board must be notified in writing that the sodium plume may extend onto an adjacent Indian River County property and that monitoring with specific conditions rather than further assessment has been granted at this time . A copy of this letter shall be provided to both parties. Please provide copies of your letters to the Department. If either party requests that the plume be defined further, then the Department will require the extent of the sodium plume to be defined completely. • The parameters of analysis shall be total dissolved solids, chloride, sodium and sulfate for groundwater samples. The field measurements during purging shall be temperature, pH, specific conductance, turbidity and dissolved oxygen. Purging and sampling methods in the Department 's Standard Operating Procedures shall be followed. • Reports for each groundwater monitoring event shall include a cumulative summary table of all groundwater monitoring results including from assessment phases. The parameters reported in the table shall be pH, turbidity, total dissolved solids, chloride, sulfate and sodium. Reports shall contain a map depicting the direction of groundwater flow and maps depicting plumes . Reports shall contain copies offield sampling logs and laboratory reports. • The number of wells and monitoring ftequency of the groundwater monitoring plan may be reduced in the fixture after a sufficient number of reszxlts are reported and a request is submitted. The proposed scope of work summarized below is intended to only provide reporting documentation regarding the implementation of the NAM Plan for quarterly monitoring (four monitoring events total ) for a duration of one year at the Site and respond to FDEP comments in a cost effective manner . Please note that IRC has indicated that they will subcontract the sampling activities and provide Geosyntec with documentation from the sampling efforts that will be compliant with all applicable FDEP guidance and standard operating procedures ( SOPs ) . PROPOSED SCOPE OF WORK Task 1 through Task 4 — NAM Report Preparation (4 Quarterly Submittals) For each event, upon receipt from IRC of the final data package of the field activities and the laboratory results of the groundwater sampling effort, Geosyntec will evaluate the data and incorporate these findings into a quarterly report for submission to FDEP within approximately 60 days from the date of sample collection , as proposed in the NAM Plan . As a contingency required in the 21 December 2009 FDEP letter, if sodium concentrations increase above the XR10051 /XR10051 IRC North RO NAM Reporting Proposal . Doc engineers I scientists I innovators Mr . Terry Southard 24 March 2010 Page 3 current concentration of 213 milligrams per liter ( mg/ L) in the groundwater samples from MW06 then additional assessment and /or reporting may be required to evaluate the extent of horizontal contamination in groundwater near MW06 . If we find during completion of this task that additional sampling and /or reporting work, is necessary , we will discuss our recommendations with you and seek approval prior to proceeding . For each of the proposed quarterly NAM monitoring events , Geosyntec ' s Findings obtained through the evaluation of the sampling documentation provided by TRC will be presented in a report for submission to FDEP . Please note that Geosyntec has included budget in this task for the review and evaluation of data package by IRC 's subcontractor of the field activities and the laboratory results of the groundwater sampling effort. This report will provide details of the work performed by IRC ' s sampling subcontractor including sample locations , sampling methodology , analytical results and groundwater elevations . A draft report will be provided to You for review and comment before the final version is submitted to FDEP . Geosyntec will submit one hard copy and one electronic copy of each final quarterly groundwater NAM report to the FDEP and one hard copy and a PDF on CD will be provided to you . ASSUMPTIONS In addition to the above , the following assumptions were made in developing this scope and cost estimate : ® As IRC requested be done , IRC will address all related issues regarding the following text contained in FDEP ' s letter dated 21 December 2009 and provide Geosyntec the related documentation : The Manager of the Indian River County Department that resides on the property to the west and north of the Indian River County North RO facility must be notified in writing that the sodium plume has been partially defined and may extend onto the property west of the site and that groundwater monitoring with specific conditions has been approved instead of further assessment at this time.
