Dear Ms. Fliss:

As per Supplement to Master Agreement For hazardous Substance Or Petroleum Response Services between the Indiana Department of Environmental Management and Earth Tech, please find the Monthly Report of Operations of the Illinois Central Spring Treatment Plant, Bloomington Indiana for the reporting period of December 2002.

Operational Status - Plant operations for the month of December were for the most part normal. Highlights of the month are as follows:

Precipitation recorded for the month was 3.95 inches. The National Weather Service records show that the historical average rainfall for the month is 3.38 inches. During this reporting period the ICS rainfall schedule was corrected to reflect the 30-year average values as posted by the NWS and NOAA. The maximum rainfall during a 24-hour period was on December 19 with 0.68 inches recorded. Approximately 1,308,568 gallons of spring water was taken to storage with 988,928 gallons drained and processed through the treatment facility during the month of December. Some 319,640 gallons of spring water remained in storage at the month's end.

A total of 11,258,428 gallons of water was processed through the facility for the month of December. No overflows of the SRS Tanks or the SRS Sump were recorded for the period.

Portable samplers (ISCO) have been placed at the overflows of the SRS Tanks since October 2002. As of this date there has been no overflows of the SRS tanks since the samplers were placed. The samplers are set with automatic triggers that will initiate the sampling sequence during the next overflow event. This program is designed to measure certain parameters they are indicative of the water quality that overflows the tanks. Measurements are primarily limited to TSS & PCB. The results will be compared to the SRS influent for the same time frames.

Corrective Measures Taken or Planned in the Month of December.

a. Internal discussions are on going concerning the stability of the electric supply to the site. The most recent failures of equipment may be due in part to over or under voltage, lightning, or spikes. Equipment to partially rectify these problems is being considered. A secondary benefit to correcting these problems would be an increase or correction to the facilities power factor. An increase in the power factor would provide cost savings in the use of energy and may pay for itself in less than three years without any consideration for the longevity of the equipment.

b. An infrared red temperature gauge was obtained during the month. Baseline temperatures of bearings, panels, and other electrical / mechanical pieces of equipment are now being monitored. The tool may allow the operator to find problems prior to the equipment failing. Though we have not been experiencing any measurable downtime or equipment failures, this tool will help with the continued success of the preventive maintenance program.

c. Access for maintenance to the high bay ventilation units is very limited. Quotes are to be obtained for the placement of dedicated ladders to access the units.

d. Heating elements were replaced in the space heater within the SRS Building.

Unexpected Maintenance Requirements

No unexpected maintenance or operational problems were experienced during the reporting period.

Analytical Results - A summary of the analytical results for the reporting period are attached to this report (See "Event Sampling Analysis"). Results for the month in review that are not currently available will be shown on the report without the test result. The log will be updated each month.

Evidence Of Trespassing

Report from Visitors Log / Plant Access

The Visitor's Log is available for inspection at the ICS office. Copies of this log are available to authorized personnel upon request and authorization of the IDEM Project Manager. There were no telephone calls requesting tours from the general public. A request was received from Tom Alcamo of the U.S. EPA to have their legal counsel tour the facility on 12/3/02. Ken Theisen of the U.S. EPA also requested access to the site on 12/19/02 for Richard Carl of the U.S. EPA to review the site. Viacom had requested and was granted general access to the spring side of the project during the month for various sampling events. Access by Viacom is recorded on the Visitor's Log.

Summary of Costs

Total costs for the reporting period of December 2002 (11/23/02 to 12/20/02) were $25,833.84. Project cost for the Fiscal Year to date is $122,312.79 with a cumulative project cost of $373925.22 since August 1, 2001 less any expenditure that have not been approved by the agency. This accounts for approximately 33.81% of the fiscal years project costs as of the reporting date.
