ELI O O 19. A survey drawing must be submitted within sixty (60) days following monitor well installation showing the location of all monitor wells (active and abandoned), water bodies and waste filled areas. The location of features on the survey drawing must be horizontally located by standard surveying techniques. The survey drawing shall include the monitor well name and identification number as well as location and elevation, referenced to NGVD, of all wells, permanent benchmark(s) and/or corner monument marker(s) at the site. The survey shall be conducted and certified by a Florida Registered Surveyor. Prior to installing the monitoring wells, a pilot standard penetration test (SPT) boring will be drilled at each location. CDM will review the soil boring log prepared by the driller and visually classified in the lab according to the United Soil Classification System to select a preliminary screen interval for each monitoring well. CDM will then specify where the grain size analysis should be completed to properly size the sand pack and screen slot size for each monitoring well. During construction of the monitor wells, CDM will provide oversight of the drilling and classification of soil types from the pilot soil borings. CDM will also provide construction oversight during monitor well installation. After the monitoring wells are constructed, they will be developed by pumping until a clear water sample is obtained. After all of the new monitoring wells are installed, a registered professional land surveyor will i locate each monitoring well relative to the State of Florida Plane Coordinate System (NAD 1983). The land surface elevation and top of casing elevation for the five additional wells will be tied into the National Geodetic Vertical Datum (NGVD) of 1929 by a professional land surveyor. The surveyor under contract to the Indian River County SWDD will perform this work, as directed by Indian River County. IV 11:0 MM After the monitoring wells have been installed, developed and surveyed, CDM will prepare a summary letter report for Indian River County to submit to FDEP. CDM will combine the results of the monitoring well installation with the results of the survey work. The report will include a map showing the final location of the five additional monitoring wells. A FDEP completion report will be developed for the monitoring wells. Additionally, the coordinates and reference point elevation for each monitoring well will be listed in a table. wm�It is estimated that it will take approximately six weeks from the time that CDM receives notice W I to proceed to complete the work outlined in Tasks 100 and 200. k0169ural B-2
