15. The system should be operated such that the capture and containment of the contaminated groundwater plume is maximized The system should be operated such that the discharge limits established for the NPDES permit and the final Record of Decision ROD are not exceeded To achieve these performance requirements the FE PWO system was designed to operate with two Production Wells PW operating at 600 gpm each and two Focused Extraction FE wells operating at 20 gpm each running in conjunction The construction of the production wells in the water bearing zone consists of perforated pipe without a filter pack in a sandy formation As such it is recommended that the production wells not be operated at a flow rate higher than their historic operating flow rate so as not to over stress the formation The historic high flow rates were limited by system pressures of approximately 45 psi Therefore do not operate the production wells with less than 45 psi backpressure If wear has reduced the capacity of the pump the backpressure may be reduced further in order to keep capacity at a minimum of 600 gpm Currently the production wells are operating with 55 psi backpressure at approximately 800 gpm Production well backpressure can be adjusted by opening or closing the gate valve adjacent to the production well and observing the upstream pressure gauge The FE well construction consists of a filter packed well screen in the target

28. PURPOSE A Signet 8150 battery powered flow totalizer provides the measure of flow rate and total flow from each of the focus extraction well pumps e This flow totalizer is a paddle wheel type recorder Operating experience has shown that scale periodically builds up on the paddle wheel and piping enough to stop operation of the flow totalizer and indicate zero flow e Scale also builds up on the throttle isolation valves which require maintenance in order to gain complete shut off of the valve and isolate the affected piping system e Following is a procedure for determining if the flow meter is plugged and the steps necessary to clean the flow meter SEQUENCE OF OPERATION Determine If Flow Meter Is Plugged 1 If the FE flow meter is indicating zero flow slowly close the throttle valve downstream of the flow meter 2 Observe for increased pressure at the pump discharge pressure gauge and listen for increased noise coming from the throttle valve 3 If pressure and noise increase and the flow meter remains at zero the meter is likely plugged Follow the steps below to clean the meter 4 If the pressure does not increase above line pressure verify that the pump is on 5 If the pump is on but not able to exceed line pressure then repair replacement of the pump is indicated Clean FE Flow Meter 1 Complete the Focused Extraction Well Pump System Line Breaking Procedure MP 02 2 Carefully unscrew the sensor cap mountin
