Britta- Here are the rates that we were discussing earlier. This is daily rates for ACE' S involvement and then the ratesheet for Thompson Pump showing the monthly, weekly and daily rate. As you can see, the longer the system is in usethe cheaper it is.

Charles- I still need to get us covered for the machine and operator time for installing the temp influent wet well pumps

that we pulled out of PCO 25.

I will also need to get the plug reinstallation cost covered but that isn' t a daily rate so it isn' t included in the attached. Should I do a separate PCO to get those two costs covered? How do you guys want to handle this?

Britta- Each of the bypass pumps that have not run in a 24 hour period must be started and run for approximately 30minutes in order to maintain battery. This is especially true for cold weather months as cold weather will sap a batteryand freeze the volute and vacuum priming chamber if left too long without running. So every day that the system is notonline all 6 pumps must be started up, primed and run. We also have a sheet that gets filled out during working hours, once first thing in the morning and once at night to review things like, fuel level, battery level, coolant level. We checkthings such as looking for leaking air releases or piping, cleaning of transducers.

The monitoring cost is a level cost per day and would cover if we had to come in at night and address a problem, brokendown pump etc. You would not get charged a separate cost for those items.

Sampler and plug rental back up attached.

The fuel rate listed is based on the OPIS average plus the fuel suppliers handling fee. It does not include tax.

Regarding only utilizing half of the bypass system, I am not sure if that is a good idea. The purpose behind having it onsite would be for failures at the new PS or if the new pump station needed to come off line for additional cleaning in thewet well. If you only have half of the system and the plant is putting out more flow then that half can handle, you wouldbe in real trouble. I will ask Thompson for a half system rental rate though.

Wendy,

I have a few questions in regards to the ' Bypass Monitoring PCOs':

Non -Fuel Option:

The PCOs lists 3 total man hours each day to monitor the system although the system isn' t running. Isthat a carryover from the other PCO? If not, please clarify in further detail what this monitoringconsists of. Did you have somebody come out last Saturday and Sunday to perform this monitoring?

Please provide back -up for the plug rental and sampler.

Fuel Option:

Is your unit cost for the fuel pre -tax or already taxed? Please provide back -up for the plug rental and sampler. The PCO lists a total of 4.5 man hours to monitor and maintain the system. Is this an average number

to cover days that require more maintenance than others and off -hours maintenance? Do you monitor

the system only during regular working hours?

I am not able to come to todays meeting but Charles will be there. I had a good conversation with Stephen

yesterday and he suggested a few cost savings options to the County in regards to the water quality and pumpperformance issue. He suggested to keep only half of the bypass pumps at this time (our Utilities group wouldhave to agree to that first). In the meantime, could you ask Thompson for a rate sheet if we utilized only half

of the existing bypass?

Thank you,

Britta
