The new GWM wells will be installed <br />in Caltrans right-of-way, in accordance with the project's work plan. Caltrans has signed a memorandum of <br />understanding (MOU) allowing the County to install the new GWM wells on their property. <br />As described in the revised EMP plan, we first intend to drill with an 8" auger, then push a hydropunch probe <br />into the aquifer to take a ground water sample and elevation measurement. After two weeks or so, when the <br />result of the groundwater analysis is evaluated, we will install a permanent well at that location, or abandon <br />it. Installing a permanent well will involve drilling through the existing borehole with a 10" auger, and then <br />installing the well. The well installation phase will take approximately ten (10) working days. <br />I anticipate that EHD inspection will be needed for well installation, but not before. With that in mind, we <br />plan to give EHD the five-day notice prior to drilling the 10" hole. Please let us know if this is satisfactory. <br />As in the past, our Contractor (Gregg Drilling) understands that EHD inspection can be from 9:00 am to <br />3:30 pm Monday to Friday. <br />The Water Board requires us to submit a GWM installation report for the new wells by December 15, 2011. <br />We plan to start this project soon upon EHD's approval of the drilling permit. Please expedite the permit <br />application process to meet the deadline. Payment for all permits and inspections for this project will be <br />made through Inter County Departmental Transfer. Please submit permit and inspection fee invoices for this <br />project to Lori Brown in your accounting division for processing.
