He described the positioning of the fence according to concentrations of PCBs, the characteristics of the fence as well as all the activities related to it. He also explained the problems encountered. Diane Henshel asked Dan Hopkins if any congener analysis were done. Dan Hopkins answered no, because the literature is referencing Aroclor analysis and not congener specific. Diane Henshel added that studies have been presenting congener analysis for years. Dan Hopkins said that he would welcome any more recent research done on that. Dan Hopkins said that all the contaminated material contained the liner system at ABB had been removed and transported, the gravel lining underneath the first liner has been removed and the places where there were tares will be sampled. To that date 24695 tons or about 268 railcars had been removed. Dave Porter asked what the average concentration was. Dan Hopkins answered that they didn't know the precise number but each truckload was sampled. He said that the average could be between 100-400 ppm, but that the range was wider. Diane Henshel asked why the spills were not handled outside the consent degree. Hopkins answered that they were not handled as consent degree sites, and that it had not been cleaned because they did not think that by doing so it would prevent the migration of the PCBs and that removing the sediments could be worst. George Hegeman asked that given the fact that the PCBs were migrating and if they are a threat to human health, it is important that whatever is done in Lemon Lane should be done as soon as possible. Dan Hopkins said he agreed with that. Melissa Valentin asked if there were any guidelines for evaluating where the point is when an action should be taken. Dan Hopkins answered that a risk based analysis is done. Melissa Valentin asked what the risk was. Hopkins answered that the risk was in the order of ten to the minus fourth or fifth and that they not only looked at the concentration but at the exposure scenario, and that the area was not somebody's backyard and the access was difficult. Melissa Valentin asked if Hopkins said that during the May Storm Sampling Event for Illinois Central and the Packinghouse/Slaughterhouse Springs. He said that they did not find any PCBs at Slaughterhouse but the results at Illinois Central were a completely different story, they just blew it out all over the place. Valentin asked if this was a one time event or if another large storm event could cause contamination to be released through the storm system again. Hopkins said that this is not a one time event. Hopkins said that they have always had PCBs come out of that spring system and the issue has not been whether or not it comes through but it has always been a matter of how much comes through. Hopkins said that he has not drawn a conclusion about what action should be taken. Hopkins said that if they build a wall to divert the water from the swallow hole that they could create another swallow hole in the process. He said that it is not a straightforward problem. Rice asked if EPA is aware of the stream across from Fell Iron and Metal site, on the east side of Rogers and the North side of the railroad tracks. Hopkins said EPA has sampled there but the levels were either non detect or very low. Is it possible that you could use the fact that it is forming a funnel, to filter it artificially at the swallowable. Hopkins said that he feels that it is possible to do that but he will have to talk to his geologist about that. Porter said that EPA says that they are putting out a fire by putting up a fence. Porter said that EPA says that there are pounds of PCBs coming through and every time there is a storm event the PCBs are going to flush through. Porter said that a fence is not going to stop the PCBs. Hopkins said that the lion's share is not getting to Quarry Springs because it is being stopped up in the bermed area by the railroad tracks. Valentin said that she thought that at the same time they put up the fence at Illinois Central that they could also put in a filter. Hopkins said that he would look into that. Foster asked what is it going to take to call this a point source and to get a spring treatment system installed. Hopkins said that a spring treatment facility is not necessary. Hopkins said that during a storm event in May that PCBs came through with a high volume of water. He said that it would be difficult to assess what size spring treatment facility would be needed to handle the volume of water. He said it's like at Neal's Landfill. Foster wants to know if the water at Illinois Central is ever going to be collected and treated or if it is going to be allowed to go wherever. Hopkins said that he has consulted with his geologist on this issue and that it would be difficult to build a treatment facility large enough to handle the volume of water. He said that it would be difficult to find a place to put it also. Hopkins said that he does not think that something else should be done that could exacerbate the problem. Valentin said she is troubled by the idea that the problem is so large that EPA is just going to leave it alone. She said does this mean that if the problem were smaller that EPA would do something. Hopkins said that if you did not have to deal with a storm then you could have a spring treatment facility to handle the water but there are storms. Cartmell asked why you couldn't have a lagoon to collect water during storm events. Hopkins said that would not be an attractive proposition for this area. Porter said that leaving a continuous discharge is not attractive either. List said that he thinks that EPA needs to do something to keep the PCBs from leaving the swallowhole but that it is all the more reason why something needs to be done at Lemon Lane. Hopkins said that he agrees with List. Foster asked if an NPDES permit was required? Hopkins said that requiring a permit would not solve the problem. Valentin said that requiring a permit would ensure that certain standards were attained. Ramsey asked who would be required to obtain the permit. Valentin said that determining who is required to obtain their permit should not be the problem. Hopkins said that not having a plant is a lot different than having a discharge from the mouth of a spring. Hopkins said that maybe an interim solution is necessary. List asked if there were a time frame associated with the cleanup remedy if that would put enough pressure on Westinghouse to arrive at a solution and if they did not then this point source would have to be dealt with. List said this would give a sense of urgency. Hopkins said that he thinks that a great deal of urgency has been placed on this site and the findings. Hopkins said that the PCB contamination could have worked its way into the fractured bedrock so that no matter how much digging is done, the PCBs may not come out for a thousand years. Foster said that he has documentation showing EPA sampled that area in 1982 and found it coming through then and here it is 1995 and EPA is still saying that it is coming out today. Hegeman said that this is pointing out that this is one of the most pressing cases where there are routes of exposure and residences near the site. Hegeman said that this really puts the screws to the process. Hopkins said that EPA is diligent about getting the conceptual plan started at Lemon Lane. Lemon Lane Conceptual Sampling Plan Hopkins presented a draft of the results of the geophysical survey that was done about the 20th of June at Lemon Lane. Cartmell said that the PCBs would not necessarily be found in the same place as the capacitors, because scavengers could have placed the insides of the capacitors in other places. Hopkins said he agreed with that, and that the geophysical survey was not perfect and that the idea was to find the hot spots. Cartmell said that with geophysics they would not be able to locate all hot spots because of the scavenging. Hopkins added that is one of the reasons why they were planning the boring. Melissa Valentin asked what would happen if they put a boring where there is a lot of metals and they don't find a hot spot. Hopkins answered that they knew where some hot spots were and that the geophysics helped confirm that. He also said that the hot spots showed in exhibit seven of the consent decree will be investigated. And that aerial photographs together with the geophysical survey data was the best way to locate hot spots. He added that they would put borings were the instability of the site was greater, like the sink holes. Foster asked how deep the borings would go. Hopkins said that the borings would go down to the soil but not further than that. Foster asked if the boreholes were going to be filled with anything. Hopkins answered that they might put the trash back in the hole. Diane Henshel asked if they were going to place the trash back in the boreholes before they new what levels of PCBs they contained. Hopkins answered that they would use field measuring equipment. Henshel asked if it was a good idea to put back materials with high PCBs concentrations. Hopkins answered that it depended on what it was. Valentin said that the immunoassay test had not been used before for landfill materials and that laboratory analysis should be used. Diane Henshel and Melissa Valentin were concerned by the fact that the sampling would not include dioxin. Hopkins said that it could not be done because of economic limitations. Foster asked what the result of the sampling was if they already knew what was there. Hopkins answered that the objective was the removal of the hot spots. EPA Budget Hopkins said that there had been a hundred million rescinsion from Superfund on a National level and 8.5 million dollars from Region 5. Hopkins said that this affected the fourth quarter funding and resulted in a significant decrease in the community relations budget. He also stated that there is no funding for the ground water sampling planned for all the sites. He added that there was no funding for the Lemon Lane Landfill exploration. He continued that what was emphasized was emergency type threats, construction completion, and what was deemphasized was responsible party oversight, the beginning of new efforts. He said that everything that is being done in Bloomington falls into the latter category. Hopkins also said that although that decision affected EPA, they will emphasize these types of efforts. Ramsey said that she is asking her department head about the possibility of IDEM picking up some of this effort but believes that they will say no. Hopkins said that the nineteenth of July he made a visit to Winston Thomas and Lemon Lane with an ecologist from EPAs Edison NY office, and ecologist from their office and Dan Spargo to familiarize the ecologists with the sites to develop sampling plans. He said that it seemed that the Emergency Response Team (ERT) in Edison, NJ had money. Foster asked what the additional testing at Winston Thomas was going to tell them. Hopkins answered that it would provide a lot of information from the ecological point of view. He also said that the information was important because it would determine if the situation could be handled outside the consent decree as a time critical scenario. List asked how far they were from taking any action at Winston Thomas. Hopkins said that something should be done as soon as possible and that he has been trying to get money and communicating with the neighbors. Hegeman said that it was the easiest site to handle and the ideal target to emergency action. Hopkins said he had problems with the threshold of getting into an emergency action, that they were working as a group and that he thought that it would happen. Henshel asked if emergency responses were defined only on humans effects or on also on wildlife effects. Hopkins answered that both, but human were a stronger case. Foster asked if there had been any sampling done outside the fence of the treatment plant. Hopkins said that they did some in ninety one and that John Langley had recently done some more. List asked what was been done to fill the gap of knowledge. Hopkins said that the biggest thing was being able to get to it. List asked if there had been anything done about notifying the school kids about Illinois Central Novak answered that what they had was in the planning stages and that they were thinking of preparing a fact sheet for kids K-6 that Sona Chambers had a draft of it. He said that they would notify the schools and provide copies. He added that when Fell is finally approved the entire situation would be addressed. Novak said that they were discussing getting a mime to communicate with the kids. Valentin asked if there were going to be responsiveness summary regarding ABB and Fell comments. Hopkins said that ABB's had already been distributed. Novak said that everybody who submitted a comment got a copy. Valentin asked about the QAPP. Hopkins answered that he had brought a copy of it. He also said that Westinghouse and EPA had different QAPPs. Adjournment The meeting was adjourned by Michael List at 9:32 pm.
