Dear Ms.Fliss:

Operational Status - A storm event occurred on September 9, 2001 with a duration of 11 hours and a total recorded rainfall of 1.51 inches. Peak facility flow rate was 1093 8pm. A total of 60,134 gallons of water was diverted to storage during this storm event. Stored water was treated on September 10, 2001. No bypass of treatment occurred during this storm event.

There were four incidents during the reporting period that impacted facility operations. None of the incidents were considered significant and as such did not impact overall facilty performance. Complete incident reports are attached to this report.

• On August 24, during a download of flow data from the Isco data recorder, the COM Port on the office computer failed. A service technician from PC Max determined that the COM Port failure was on the computer mother board and was not repairable. An auxiliary COM Port was installed and configured for downloading flow data. On August 28, 2001, a lightening strike burned out the auxiliary COM Port. This auxiliary COM Port was replaced and is now functioning properly.
• On September 7th and 9th, storms caused power outages and /or fluctuations at the facility. As a result, the automatic samplers did not operate continuously.
• On September 19, 2001, the operator received a level II alarm on the plant air compressor. Troubleshooting using the O & M Manuals and Ingersoll-Rand Tech services did not clear the problem. Ingersoll-Rand sent a service technician, who was able to correct the problem.
• On September 10th, the operator received a Level I alarm for power loss. The auto start of the generator functioned properly, however, Pump P-107 showed "Failure" and pump P108 showed "Voltage Overload". Pump P-107 was reset and successfully restarted. Pump P-108 required additional troubleshooting to clear the alarm condition.

Corrective Measure Taken or Planned

• The connection from the COM Port to the data recorder will be kept unplugged except during times of downloading flow data.
• The automatic sampler will be monitored during power losses or fluctuation and reset as required.
• The probable cause for the air compressor fault was due to an improper setting or stray under voltage with the power supply. Operator will monitor situation to identify future problems.
• Pumps P107 and P-108 will be monitored to identify additional problems.

Analytical Results - Analytical results for the reporting period are attached to this report on the Event Sampling Analysis Log.

Unexpected Maintenance Requirements - There are no unexpected maintenance requirements listed in the attached Incident Reports.

Evidence Of Trespassing - There was no evidence of trespassing at the facility during the reporting period.

Report from Visitors Log - Copies ofthe Visitor's Log are attached. There were no telephone calls or requests for tours received from the public.

Summary of Costs - Total costs for this Project for the month of September 2001 was $16, 475.21. The summary of cumulative project costs and comparisons to the project budget are attached to this report.

Incident Reports

• On August 24, 2001, Mr. Doug Gripp of Gripp, Inc. on site to download data from Isco data recorder to troubleshoot problem with the flow measurement data. Was not able to connect office computer with remote location. Mr. Gripp and the project Engineer troubleshoot problem with connection to the computer. Determined that the problem is with COM port of the office computer. Due to the time of day and it being Friday, will call PC Max on Monday.

  Contact PC Max on Monday, August 27, 2001 and they send a service technician to the site and confirm that COM port #2 on the motherboard is not working. This is not repairable. Computer does however have a connection to add an auxiliary COM port. Insert new card and reconfigure computer to use new port.

  On August 28, 2001, the Bloomington area experienced a severe thunderstorm with the ICS plant having a close by lightening strike. This strike caused the of fice computer screen to go black and it would not restart. The storm occurred late in the day, so PC Max will be called in the morning.

  Contact PC Max the morning of August 29, 20GI. Service tech is sent to site. Troubleshoots problem and finds that new auxiliary COM port replaced on August 27th has burned out. It had evidence of blisters due to stray voltage on the integrated circuit chip. Replace with new board and it works.

  To prevent this from happening, Earth Tech is going to leave the remote connection to the Isco data recorder unplugged and will only make the connection when downloading data.

• On September 19, 2001 the operator on call received a level II call-out for an alarm on the plant air compressor. Used operations and maintenance manual to try and trouble shoot problem. Manual outlined 4 possible causes, and operator was able to eliminate two. The remaining required more technical support.

  The next morning, September 20, 2001, the operator called tech support at Ingersoll-Rand. Service manager walks through remaining 2 causes, but could not get compressor to reset. Ingersoll-Rand sends tech to site. Trouble was with an adjustable circuit breaker that was set improperly. Adjusts breaker and compressor then would reset and run. Tech checked voltages and currents for all other components. All set correctly.

  Probable cause of fault due to improper setting or stray under volt or over volt with power supplies. Will monitor for any future problems.

• On September 10, 2001 the operator on duty received a Level I alarm due to a power loss at the plant. Auto start of generator successful, but received another alarm due to pump P-107 failure and pump P-108 "Voltage Overload".

  Reset and restart pump P-107 to continue processing water. Try to reset pump P-108, it will not reset. Contact Project Engineer and he makes trip to site. Use Operations and Maintenance manual to troubleshoot problem. Shut down power and take electrical measurements with multi-meter to confirm electrical continuity. Measurements are good. Re-power pump P-108 and now able to reset for operations. Later, pump P-108 auto started and operated as normal.

  Reason for alarm must have been when power failed, pump P-107 was in operation and shut down. Pump P-108 must have tried to start while the back-up generator was still starting, thus not supplying full power.

  Will monitor pumps P-107 and P-108 for any other possible troubles.
