Note that the Plan is dated December 18 and that testing is scheduled to begin this Monday, January 6. I find the state's behavior in providing the Plan for revie"v at this late time both discourteous and disrespectful I reject the entire Plan and advise the Working Group to r~ject the study for the following reasons: TI.1e key stated premise of the Plan is "it is n.ot believed that there are uncontrolled PCB emissions." And the stated objective of the study "is to test this premise by determining if there are uncontrolled PCB emissions." In other words, the "scientific" position of the state is that there are uo emissions and their study will prove this. In fact, tb.e Plan states t11at "Generally the vapor pressure of PCBs under normal conditions in the PCB landfill in Wanen County is too low for volatilization and cannot be emitted directly into the air surrounding the landfill." If this position was scientifically correct, then why did EPA conduct its study to measure PCB emissions and why did EPA actua1ly measure PCB emissions? The Working Group and concerned citizens should reject this biased state study from the outset. There is absolutely no reason to trust the study. With this kind of bias the public should not accept a state agency au.d state personnel conducting the sampling and the laboratory testing. An independent contractor and au iudependeut laboratory should be used, and the Science Ad,isors should be given adequate time to fully examine and review the details of the sampling an.d testing methods. Technically: I do not believe that the planned sampling methods are acceptable~ nor do they fully conform with the recommendations of the EPA study. It seems as if the state is committed to use any tactic to attack the previous work on PCB air emissions in the past. Even if sound sampling and testing found no PCB emissions today, it would not in any logical or scientific sense prove that there were no significant PCB air emissions in the past. Tile planned study is to include a risk assessment, but this too should not be considered objective or reliab.le by the public. ·-. P. I From: To: Subject: Ron, BOB-DR LEWIS intemet."hitesr@indiana.edu" N. C. PCB Landfill Post-It"' brand fax transmittal memo 7671 ,, of pages ► / Co. Co. Dept. Phone ;, Fax# 6 / -J ,) Z / I was sorry to hear that you are unable to help us refute the criticisms lodged against me and the EPA in connec:ion with the PCB monitoring we did at the Warren County landfill. Perhaps the package that the State sent to you was a bit overwhelming, especially at this time of the year. In brief, we monitored the landfill shortly after it was closed in 1983 using low-volume PUF air samplers and GC/ECD both for within vent measurements and ambient air measurements. We found only very low PCB concentrations in the vents, except for the main vent, where we found 120 ug/m3 of Aroclor 1242 and 2 ug/m3 of Aroclor 1242. Over two days of monitoring, all ambient air samples were found to be negative for 1242 (LOO 6 ng/m3) and below or near the limits of detection for 1260 (10 ng/m3), except for 4 of 39 samples, including two at 50 and 70 ng/m3 at the fence line (98 m from the main vent) and two {11 and 12 ng/m3) near the main vent (one upwind). We published this data, along with results from the Bloomington landfill in ES&T in 1985 {19. 986-991). In the paper I stated that these measurements did not appear to correlate with proximity to the main vent. {Note: In Table II of the paper, we erroneously listed one of the measurements near the vent as being at a nearby house. Location A-7 for the main vent was adjacent to A-8 for the house on the data·-sheet. In fact, nothing was ever detected at the house, 1000 m away.) We concluded that emissions of PCB from a well-designed chemical waste landfill were found to be negligible. Dr. Hirshhom has harshly criticized our conclusions, and somehow equated what we found in Warren County to the high emissions we found in Bloomington. In my rebuttals, pointed out that since the PCB detected in ambient air did not correlate with proximity to the main vent (and main source), i.e., concentrations were higher at 98 m than 1 m, ao_g since the more volatile PCB mixture (1242) was the dominant component in the vent as contrasted with 1260 being the only component detected in air, the ambient air detects may have been false positives. Given that we were using ECO and pattern recognition, this likelihood is high. Do you agree that (1) based on our results, PCB emissions from the landfill appear to have been negligible, (2) little or nothing was found in ambient air, (3) the ambient air results were likely false positives, and (4) the main vent was not likely the source of the PCB found in air even if the air measurements were real? If you could respond to these questions in a brief letter to William Meyer, I would be grateful. You might also add that you know of my work and have confidence in the quality of my interpretations.
