MEMORANDUM

To: Service List (attached) USEPA, Underground Injection Control Branch (WU-16J) Alan Tenenbaum, U.S. Department of Justice Mary Ann Habeeb, State of Indiana

From: Ronald E. Hutchens, P.E.

Subject: Progress Report No. 148 August 1 through August 31, 2004 Remedial Design/Remedial Action Midco I and II Sites, Gary, Indiana

PROGRESS TOWARD IMPLEMENTING THE CONSENT DECREE

• Continued operation of the Midco I and II Sites' ground water extraction and treatment systems (GWETS) and injection of treated ground water.

• Collected the monthly effluent samples from the Midco I and II Sites' ground water treatment system (GWTS) on August 26, 2004.

• Continued the review of the validated analytical results received to date for the Midco I and II Sites annual ground water monitoring.

• Continued dewatering at the Midco I Site within the containment/barrier wall.

MIDCO DEEP INJECTION WELL OPERATING CONDITIONS

• Table 1 summarizes the daily maximum injection pressure, sight glass levels, and minimum differential between injection pressure and annuius pressure. Figures 1 and 2 present the operating flow rates at the Midco I and Midco II Sites' GWTS, respectively. Figure 3 presents the daily maximum injection pressures and flow rates. The daily sight glass levels are shown in Figure 4.

SYSTEM SHUTDOWNS

• Table 2 details the Midco I and Midco II Sites' non-GWETS-related shutdowns and scheduled and non-scheduled GWETS-related shutdowns.

• The Midco I and Midco II Sites had one non-GWETS-related shutdown. On August 23, at 7:27 A.M., an Indiana Department of Transportation (INDOT) vehicle heavily damaged the injection well facility power and communication lines shutting down both sites. The Midco I Site was shut down for 4,508 minutes and the Midco II Site was shut down for 3,168 minutes.

SAMPLING AND TEST RESULTS

• The analytical results for the quarterly influent and monthly effluent samples collected on June 23, 2004 at the Midco I and II Sites were received on August 12, 2004 from the data validator. The validated analytical results are presented in Table 3 through Table 10. The effluent samples met the required Maximum Allowable Concentrations (MACs).

• The analytical results for the monthly effluent samples collected on July 14, 2004 at the Midco I and II Sites were received on August 12, 2004 from the data validator. The validated analytical results are presented in Tables 11 and 12. The effluent samples met the required MACs.

PLANS AND PROCEDURES COMPLETED UNDER THE RD/RA PROJECT PLAN

• None during this reporting period.

ACTIVITIES TO BE CONDUCTED DURING SEPTEMBER 2004

• Continue operation of the Midco I and II Sites' GWETS and injection of treated ground water.

Continued dewatering at the Midco I Site within the containment barrier wall.

PROBLEMS ENCOUNTERED AND THEIR SOLUTION

• On August 23 at 7:27 A.M., a worker for INDOT pulled down the power and communication lines as he unloaded a street sweeper. The utility pole was torn in half and several electrical components were damaged. Both Midco I and II were shut down for several days as the repairs took place. Midco II was shut down for 3,168 minutes from August 23 at 7:27 A.M. to August 25 at 12:15 P.M. As operators started Midco I at this time, additional damage was found at extraction wells 7 and 2. Midco I was shut down for one additional day until repairs could be made. Midco I was shut down for 4,508 minutes from August 23 at 7:27 A.M. to August 26 at 12:15 P.M. Custom signs will be ordered and will be placed in locations where drivers are reminded to lower booms and dumps.

Key: HP/UV = Hydrogen peroxide/ultraviolet light GWETS = Ground water extraction and treatment system gpm = Gallons per minute N/A = Not applicable ND = Not detected

Notes:

' HP/UV flow rate is the flow rate that goes through the HP/UV.

^ The upper range of methylene chloride detections at the Midco II Site is due to peak shifting within the GC caused by elevated

ambient temperatures. The actual methylene chloride concentrations are lower. ' Total treated water volume is obtained from the site treated water flow totalizer. ^ Design average flow rate is the model-predicted flow rates of 32.0 or 50.6 gpm, respectively for the Midco 1 and Midco II Sites.

The design average flow rates changed on January 28, 2002 from 16.5 to 32.0 gpm for Midco I and on February 24, 2003 from 24.5 to 50.6 gpm for Midco II.

' Average monthly operating flow rate is the total treated water volume divided by the operating time excluding all non-GWETS related shutdowns. This value is different from the HP/UV flow rate because of the flow recycled during the tube cleaning.

' Average monthly flow rate is the totalized volume of treated water divided by the number of minutes for that month.

U* = This compound should be considered "non-detected" since it was detected in a blank at a similar level N/A = Not applicable; no Maximum Allowable Concentration (MAC) has been established for that analyte

The laboratory reported the results of the original sample and a dilution. The results shown are either the highest positive results or the

lowest detection limit. Higher estimated positive results were disregarded if accurate positive results were detected.

" Blank spaces indicate that no MAC has been established for that analyte.

The MAC shown is for 1,3-dichloropropene. The sum of detected 1,3-dichloropropene isomer concentrations is below the MAC.

The concentration is approximate due to the limitations identified during the quality assurance review Compound was analyzed for but was not detected at or above the associated numerical value The compound was not detected, but the quantitation limit should be considered estimated due to a bias identified during the quality assurance review The results were considered unusable during the quality assurance review; analyte may or may not be

present in the sample

The laboratory reported the results of the original sample and a dilution. The results shown are either the I

positive results or the lowest detection limit.

Blank spaces indicate that no Ma.ximum Allowable Concentration (MAC) has been established for that are

The approved detection limit (as listed in the Quality Assurance Project Plan for the Midco Sites) is above

The concentration shown for this compound in sample 1EAM074D is likely the result of contamination di use of phthalate-containing gloves during collection.

The MAC shown is for total dinitrotoluene.

U* = This compound should be considered "non-detected" since it was detected in a blank at a similar level

N/A = Not applicable; no Maximum Allowable Concentration (MAC) has been established for that analyte

The laboratory reported the results of the original sample and a dilution. The results shown are either the highest positive

results or the lowest detection limit. Higher estimated positive results were disregarded if accurate positive results were detected.

^ Blank spaces indicate that no MAC has been established for that analyte.

' The MAC shown is for 1,3-dichloropropene. The sum of detected 1,3-dichloropropene isomer concentrations is below the MAC.
