Mike Nixon , Roadway Production Manager Engineering Division Indian River County 1801 27th Street (Bldg A) Vero Beach , FL 32960 - 3388 Subject : Professional Services Proposal — Amendment No . 1 to Work Order 24 Site Assessment Activities Former Cattle Dip Site 925593 d Street on County Road 510 Parcel #31392600000002000001 . 0 Vero Beach, Florida Dear Mr . Nixon : Geosyntec Consultants (Geosyntec) is pleased to submit this fee proposal to Indian River County (IRC) for professional services associated with the completion of a site assessment addendum at the referenced Former Cattle Dip site . The site assessment activities are based on the Florida Department of Environmental Protection ' s (FDEP) Review of the Interim Groundwater Sampling Report, which recommended supplemental groundwater assessment activities to delineate the extent of the arsenic groundwater impacts with the submittal of a Site Assessment Report Addendum ( SARA) . The arsenic groundwater impacts must be delineated to the FDEP Groundwater Cleanup Target Level of 10 micrograms per liter ( µg/L) . The proposed scope of work for the services anticipated to delineate and monitor the arsenic groundwater impacts has been broken down into five separate tasks as described below . Task 1 — Preliminary Activities Task I includes project management for the entire project, as well as all preliminary activities associated with securing project costs from subcontractors and updating the Site - Specific Health and Safety Plan to cover the additional assessment activities . Specific activities include : • Updating the existing OSHA -required , Site - Specific Health and Safety Plan ; • scheduling a utility locate , acquiring field equipment (pumps , water quality meters , calibration solutions , sampling containers , etc . ) , subcontracting ; and XR 11191 /CCR11063 . DOC engineers I scientists innovators Mr. Mike Nixon Geosyntec ' 3 August 2011 consultants Page 2 • project planning and management responsibilities, invoice review, project coordination , and project administration . Task 2 — Off- Site Access and Right of Way (ROW) Notification Packages The four monitoring wells proposed to be installed under Task 3 (below) are located off property (to the north and west of the site) . Two of the monitoring wells are located in a Florida Department of Transportation ROW, on the north and south side of State Road 510 (to the north of the site) . Obtaining access to install two monitoring wells along this roadway and two monitoring wells to the west of the site will involve a search on the Indian River County Property Appraiser website to identify ownership (State , County , City , private , etc . ) ; completing an access agreement between the owners and the county ; and most likely submission of a fee for permitting . We assume we will have to work with only two entities to get access for off- site well installations and that the effort will only involve submittal of a written request ; we have not budgeted for negotiation of access agreement terms , meetings , multiple submittals , provision of insurance, etc . Please note that as part of accessing public thoroughfares for drilling, a Maintenance of traffic (MOT) plan and barricades may be needed as part of satisfying an access agreement. A traffic plan helps address worker safety and may include flagmen and signage to warn vehicles and pedestrians of work in the area . Geosyntec can arrange for the preparation of a traffic plan , however, until off- site access can be arranged , Geosyntec cannot reliably estimate the amount of effort , and we have not included a budget for a traffic plan or flagmen and signage ( if needed) in this proposal (typically this costs less than $ 2 , 500) . Geosyntec anticipates that if an MOT is required that index 4602 for the FDOT design standards will be reference and that the duration will be less than 60 minutes , which will preclude the requirement for signs and channeling devices . Task 3 — Monitoring Well Installation Task 3 consists of mobilizing to the site and installing monitoring wells . Geosyntec proposes to install four monitoring wells using direct push technology (DPT) drilling techniques at the locations presented in Figure 1 . The monitoring wells will be constructed of 14nch PVC and will be installed to a maximum depth of 15 feet below land surface (ft BLS ) with 10 -ft of 0 . 006 - inch slotted screens with a 30/65 pre -packed sand filter. The monitoring wells located near the roadway will be completed with a 244nch by 244nch concrete pad with an 84nch manhole . The monitoring wells located in the wooded area will be completed with the 244nch by 24- inch concrete pad with a 44nch PVC casing that is approximately 34eet tall (instead of the 8 - inch manhole) . Once installed , the monitoring wells will be developed until visibly free of particulate XR11191 /CCR11063 . DOC engineers I scientists innovators Mr. Mike Nixon Geosyntec ' 3 August 2011 consultants Page 3 matter . Geosyntec assumes one day of oversight for the monitoring well installation and development. Surveying (location , top-of-casing and ground elevations) by a licensed professional land surveyor of the newly - installed monitoring wells will be also completed . Task 4 — Monitoring Well Sampling Following installation , the newly installed monitoring wells will be purged and sampled in general accordance with FDEP Standard Operating Procedures ( SOPS) . The collected groundwater samples will laboratory analyzed for arsenic by EPA Method 6010 . In addition , water levels will be collected from the newly installed monitoring wells and the existing site monitoring wells to document the groundwater elevations and flow direction at the site . The current cost breakdown of the monitoring well installation assumes only four monitoring wells will be required to document delineation of the arsenic groundwater impacts . An additional 100% contingency has been added to Task 3 and Task 4 to cover any additional monitoring well installations and sampling required to achieve arsenic groundwater delineation . Geosyntec will notify IRC and secure approval for any activities that may require access to contingency fees . Geosyntec assumes the monitoring well sampling and collection of water levels can be completed in one day . Task 5 — Site Assessment Report Addendum No . 2 Geosyntec will prepare a SARA No . 2 as a letter report after completion of the monitoring well sampling event . It is anticipated that the Letter Report will include : • brief description of field activities ; • summary tables of the groundwater sampling results and groundwater elevations ; • maps that provide a summary of the groundwater sampling results and provide a summary of the groundwater elevations ; and • recommendations . ASSUMPTIONS The following assumptions were made in developing this fee proposal : • All site work can be performed in Level D personal protective equipment . XR 11191 /CCR 11063 . DOC engineers I scientists I innovators Mr . Mike Nixon Geosyntec ' 3 August 2011 consultants Page 4 • Geosyntec will be able to work unimpeded Monday through Friday from 7 am to 7 pm . • Geosyntec has assumed that liquids generated during the monitoring well purging and sampling will be discharged directly onto the ground adjacent to the monitoring well (for percolation or evaporation) . • Geosyntec assumes that all monitoring well installation activities will be completed during one mobilization . SCHEDULE Geosyntec anticipates that upon approval from IRC , site assessment activities will be initiated within four weeks . It is anticipated that the monitoring well sampling results will be available approximately two weeks after completion of the sampling . The draft SARA No . 2 will be provided to IRC within four weeks of completion of field activities . ESTIMATED BUDGET The fee proposal is provided as Attachment B . The total estimated budget to complete the work described in the fee proposal is $25 ,759 . CLOSURE Geosyntec appreciates the opportunity to submit to IRC the attached fee proposal (Attachment B) for services at the site .
