Deb Dunn: The Deed restriction that they put on the house, does that cover the garage or would we need to put one on the garage if we agree to this?

Board of Health Meeting March 13, 2017 Meeting was called to order at 6:30pm. Members Present: Debra Dunn Dr. Brian Kelly George Smith Wade Saucier, Health Agent Liz Bugbee, Office Staff Members Absent: MINUTES George Smith: I make a motion to approve minutes of February 27, 2017 Dr. Brian Kelly: I second the motion. The minutes are unanimously accepted. NEW BUSINESS Variance Hearing 65 Lake Street: Ken McKenzie from Dunn McKenzie. I am representing Robin and Jonathan Minkin. We went through Conservation, trying to put the tight tank within the 100 foot buffer. We are looking for a variance. We are trying to put the tank in where the cesspool was. It is a tight lot. We need a 5 foot variance for the tight tank. It is a monolithic tank, it will be a little more than 2 feet under the bottom of the lake. It is 26,000 pounds and you don t need any added weight. They didn t really need a 2,000 gallon tank but that it what Title 5 calls for. This is really the only place that we can put the tank. They would have liked to tie into the original system, because it is only a toilet and a sink. It is a game room for the kids. There is a deed restriction so that this could never be turned into a bedroom. The cesspool was five to six feet from the main water line, the Water Dept. would like us to try and keep the tank ten feet away, if we can t they will work with us. Deb Dunn: The Deed restriction that they put on the house, does that cover the garage or would we need to put one on the garage if we agree to this? Wade Saucier: The restriction is for Title 5, it is a nitrogen restriction. Deb Dunn: We had discussion about this with the Minkins when they were in and we know what their intentions are but I am thinking ahead to the next owners. Ken McKenzie: I have a copy of the restriction. It covers the entire lot. Deb Dunn: Any questions from the Board? George Smith: You are talking about the tank being two feet into the water? Ken McKenzie: When you put the tank in it will be right in the water. It will go right to the bottom. I have done the buoyancy calculations. George Smith: There are no other options so that the tank does not have to be in the water. Ken McKenzie: If we had known they were going to do this when we built the original system they could have tied this into that system but now there are walls and there really is no other way to do it. Dr. Brian Kelly: I make a motion to approve the variance, to allow a tight tank to be 5 feet from the garage floor slab. George Smith: I second the motion. Motion passes unanimously. 1

OLD BUSINESS: DPW Waste Water Treatment Plant Testing Discussion: Doug Valovcin Assistant Superintendent of Public Works Deb Dunn: We are continuing the discussion of the testing parameters for the Waste Water Treatment Plant (WWTP) on Randall Road. Doug Valovcin: At the last meeting we were asking whether we had to continue doing all the testing that the Board requires. MASS DEP has a different set of testing. From the reports, most of the requirements, as far as the metals and all of that have been non-detectable, it is not something required by DEP. So we are asking for a waiver on that, and some of the frequencies are different. And I am wondering if we are allowed with the testing that DEP is looking for as opposed to the local requirements. Wade Saucier: I talked to a few outside resources. The metals have been tested quarterly, although not all of them had been tested. Fluoride, Silver, Arsenic, Barium have not been tested. I mentioned last time that regulations should be reviewed periodically, and this is one of them. Six of the metals are tested quarterly and the BOH requires it annually. I think part of the local requests have been lost over the years. The metals that are being tested are showing no detection at all. They are clean for heavy metals. 2

Doug Valovcin: This is a little cheat sheet for what the Board of Health requires and what DEP requires. There are some differences in weekly, monthly etc. George Smith: Where did this come from? Doug Valovcin: I imagine it came from the Board of Health, it was what was given out in the packet and the DEP ones came from a Mass DEP permit. I put this together as a quick reference sheet for comparison. 3

George Smith: How will this make a difference in your bid? Personally I am conservative as far as looking at these things. However if we have a history and it shows that they are not there, it would be foolhardy to keep testing. I don t think it is necessary to change our regulations. Could we give a waiver or do we need to hold a hearing for a variance? Deb Dunn: We can amend the permit as part of the permitting process. We can amend the permit at this meeting tonight, depending on the pleasure of the Board. I notice from this that some of the things we are looking for the state is more stringent. I notice ph, since these are commercial buildings. Floor strippers and all types of cleaning products can affect the ph. I wouldn t want to change the requirement for ph. Wade Saucier: The ph grab would be a DEP requirement and the Board of Health is asking for less. Doug has it backwards on his chart. It is a good example of the same parameters but different frequencies. You want to be sure that the plants are running properly. I have done a comparison chart also, only it is not as nice as yours. Doug Valovcin: I took the list from this permit. How this came to light is that the contract is expiring soon for the plant that handles the school, public safety and town hall. DPW is just managing the company that does all the monitoring. When the contract went out we realized that there was a difference and since it has gone out to bid it can make a big difference on how someone bids this. They may be able to streamline their bid by doing what DEP requires. We have extended the deadline a couple of times but we can t keep delaying the bid process. We are looking for a vote or some consistency with what needs to be tested for, this is what we have to tell the bidders. George Smith: What induced you to come here? Doug Valovcin: As I said this is going out to bid, and we are looking at this and noticing the difference between what the Board requires and what the State requires. Deb Dunn: Given what we have done with another plant, how does the board feel about, since there are no detectable limits of the heavy metals? Arsenic, Barium, Cadmium, Chromium, Copper, Lead, Mercury, and Zinc, we released that other plant from having to do that annual testing. Did we release on the monitoring wells as well or just the plant? Wade Saucier: I think it was pretty generic. Deb Dunn: It was for both. George Smith: Is that a permanent change? Wade Saucier: You can add them or take them off at your leisure, annually if you like. George Smith: I am conservative when things come to public health, I wouldn t want to this to be forever, if something were to change Deb Dunn: A use could change. We can modify the permit to release them from the heavy metals and to clear up the frequency issues, they can use the DEP requirements unless Wrentham is more stringent. So you will use the more stringent of the regulations between the two it should be worked out. For example BOD5. The State wants it weekly, Wrentham wants it monthly so in this case the State is more stringent. Total Nitrogen the State wants it weekly, we want it monthly. So you will use State DEP unless Wrentham is more stringent. Doug Valovcin: So we will receive relief for the effluent and the monitoring wells? Deb Dunn: Yes, assuming the Board is in agreement when we vote. You will receive relief from Arsenic, Barium, Cadmium, Chromium, Copper, Lead, Mercury, and Zinc, not Total Phosphorus or Orthophosphate. Doug Valovcin: Wade mentioned fluoride and a couple others which I did not see in the DEP requirements. Wade Saucier: They are quarterly testing the heavy metals. That is part of the review of this regulation. Fluoride is on the local list. Doug Valovcin: My question is if there are additional things. I imagine this list came from the BOH that were in the bid packet and some of the things you just mentioned were not on the list, so if they need to be added, maybe this is an outdated list. Deb Dunn: I have never seen that list. (Wade hands out the regulation) 4

George Smith: You get documents and you have no idea where they come from, there is no heading on it. I think even between ourselves we have to know where things came from. Doug Valovcin: It just says Wrentham Board of Health. Wade Saucier: There are also no parameters on it. George Smith: I know on the DEP regulations there are a ton of things that we can t override. I wouldn t want to change the regulations. So, it would be good to modify the permit but not changing the regulation. Wade Saucier: The testing is so that the technicians can monitor the plants and make sure they are running properly. If you asking for too much you aren t helping the plant in the long run. George Smith: Well there is always a starting point and then you go from there. If might give a little bit of history, we were treating metals. We had companies that came in that wanted to do zinc plating, so I wouldn t want to change the regulation. Wade Saucier: I think that is reasonable. You can look at what the plant is going to produce, so arsenic may not be coming out of the school but they are paying for this to be tested. Dr. Brian Kelly: One size does not fit all. Deb Dunn: I think it was written to encompass everything, with the option to take things out. You can take things out but you cannot add them if they are not in the regulation, but we can remove certain things if they are not appropriate. George Smith: I think it is important to take into account the history so we know why these things were being required in the first place. We have a brown spot at the town dump from dumping that took place there years ago that has never been cleaned up properly. Deb Dunn: That is an important discussion but it is for another day. Wade, trihalomethanes? Can you help me out with that one? Wade Saucier: They break down chlorine that is found in water. Deb Dunn: So if we don t have a pool there? Wade Saucier: Or even if your water is chlorinated Doug Valovcin: The water is chlorinated. We will be testing for trihalomethanes, they are not a problem at the present time. Wade Saucier: You test right from the pipes itself? Doug Valovcin: We do sample at the source but we also test at random locations throughout the town. Wade Saucier: Do you think there would be such a buildup that it would show up in waste water? Doug Valovcin: I have never seen that. Deb Dunn: At the other plant we looked at pesticides and radio activity on the five year. Wade Saucier: You are looking at the plant and what they are producing. On pesticides, it would depend on the plant and what they are producing. I think it would be site specific. Deb Dunn: Radioactivity, I would imagine you are in the same Wade Saucier: Radioactivity, maybe Doug could help us out with that. If there is high radioactivity in the water source. Deb Dunn: I know we have to have wells in the southern end of town tested for radioactivity at point of sale. It s the rocks, it is the geology, we have zones in Wrentham and not everyone is in them. 6

Doug Valovcin: Some of these tests like the radioactivity they are on the drinking water side. If it is nonexistent on the drinking water side, I can t imagine it would be in the waste water. Every one of these things is hit within that three year cycle. I don t believe Pesticides are not part of the drinking water, not radioactivity but tests along those lines that are done on the drinking water. Deb Dunn: I make a motion that we allow the treatment plant run by the town of Wrentham that services the school, the public safety building and the town hall, to modify the permit to delete from the effluent and monitoring wells testing for Arsenic, Barium, Cadmium, Chromium, Copper, Lead, Mercury, and Zinc, Silver, Selenium, Fluoride, Total Trihalomethanes and to remove the five year requirement for Pesticides and Radioactivity. Also, as regard the testing frequencies the DEP testing frequencies will be followed unless the Town of Wrentham s in more stringent. So the more stringent testing will be followed whether it be Wrentham s or DEP s. Dr. Brian Kelly: I second the motion. The motion passes unanimously. The permit is amended. Doug Valovcin: You had said effluent as far as heavy metals. Deb Dunn: Effluent and Monitoring Wells. George Smith: The Board should send a letter to the DPW outlining what we have agreed to. Doug Valovcin: We can amend the bid package and get it out knowing that there is a letter coming from the Board. 730 Madison Street Deb Dunn: I did fill out a form that I have watched the last meeting on the internet. I am up to date, I have filed the paperwork with the Clerk s office and am able to fully participate in the conversation. Kevin Erikson: We had met before this board looking for four variance and we are now down to three. One was for the percolation testing pertaining to the time of year that testing was done but we have withdrawn that request and done the testing according to your regulations. We did make some changes to the design since the last meeting. I do apologize if I sound like an ignoramus when it comes to this stuff, I am a lawyer, and I am not an engineer. Mr. Peznola had an unavoidable conflict. We did increase the area and changed the type of unit, we are now using stone trenches, which I understand it preferred by DEP and this relates to the LTR effluent loading rates, so to supplement the justification for that variance. We have increased the size and number of grease traps and proposed a more aggressive venting system. One was designed by Hancock and one was recommended by Mr. Saucier. Those all go towards the effluent loading rates variance requests. The other two variances have to do with the maximum depth, DEP doesn t have a corresponding requirement. It is my understanding that these are big systems. The narrow tanks that could comply with the bylaws, are not as structurally favorable, and it is my understanding that some of the manufacturers won t even warrant them long term, we are proposing what we see as a better system overall but it does require variance relief. And then the spacing we are looking for six feet, where ten is required. Wade Saucier: Here is a set of plans. I was talking to Ed Cullen one of the design engineers. I said you are going for Board of Health variances so I will do a light review on the plan in case the variances are not approved. We will go with the concept in case the variances go through. They did change the leaching facility, because the first one, the unit wasn t made yet. We took another unit, because the other one was not going to be available. Deb Dunn: If I recall the manufacturer was making promises. Wade Saucier: They came up with another unit, and also with this unit there is an elaborate venting system. I called the Cultex salesman to ask about the specs on it. He (the design engineer) wants to use this hole, it looks like it is 4 to 6 inches (points to the plan) for the entrance of two pipes, I thought he was going to drill a hole in it and ruin the integrity of the unit. These are the small details that they are trying to work out. They want to use this plastic unit to increase the oxygen into the field. George Smith: Is this what they were planning to do or is this per this plan I have in front of me. Wade Saucier: This is per this plan. This is a different Cultex unit, which has an H Twenty rating, the other one did not have that. George Smith: How wide is it? I don t think that is on here. Wade Saucier: I think it is on there. The width of it is sixteen inches. 7

Deb Dunn: But it is rated for under the parking lot, for vehicle traffic. Wade Saucier: Those are just the small details, but if you would like to go through each variance and we can discuss them. I will give you an objective viewpoint. I am not on the applicant s side, I am right in the middle. I am here to advise the Board of Health, it is odd that the design engineer is not here to present his work. Deb Dunn: (To Kevin Erikson) You should let Mr. Peznola know that the Board was disappointed that he was not here this evening. George Smith: I don t think that this Board should be designing anything. Wade Saucier: I agree with you, I am not designing, I am discussing the variance requests with you. Deb Dunn: If Wade can work with an applicant and get them from five or six variances down to two or three then we are better off. I value Wade s opinion and I want to hear it, even if it differs from my own. Wade Saucier: The variance letter was originally written December 23 rd and then revised January 23 rd, the first one they wanted less test holes and perc tests than required. Kevin Erikson: We withdrew that one Wade. Wade Saucier: I realize that but I am just going over everything. Deb Dunn: We will reflect it as withdrawn. Wade Saucier: Septic Tanks, Section 7.3 septic tanks. The local regulations require tanks of certain sizes to have a certain depths. Applicant is seeking to have regular title 5 tanks on site with the depths that are provided by the size of the tanks. Not being the original author on this regulation there might have been a concern regarding depth but there is no explanation to the regulation so I am not sure what that concern might have been. The tanks have their volume retention times, but the depths of the tanks, I m not sure why. These tanks have their own depths. I don t know why the depths were shortened. There is an advantage to having a deeper tank it that the sludge can accumulate at the bottom and the sludge can be independent of the water and the grease. You have less total suspended solids. Deb Dunn: Will this keep it a monolithic tank? Wade Saucier: A monolithic tank is like a box with a top in it. There is no seam so it is more water tight. These tanks are large, I didn t get to review it to see if it is sitting in groundwater, if it is the best thing to do is have a monolithic tank, because it s heavy and Title 5 requires that the water be at least 12 inches below the outlet tee. Deb Dunn: I remember hearing that there was potential for uneven groundwater, but that was corrected. George Smith: How was that corrected? There are pipes out there that are supposed to be monitored. Wade Saucier: We were seeing variations on groundwater. But we went out there and did our own observations. I was there when the pipes were originally installed, sometimes they can be at a slant, they could be dirt fallen in them. I am not a fan on pipes, that s why we went out there during high groundwater season. I did drop a tape into them and we did find water in the pipes, but I think deep groundwater observation holes is a better analysis. We have numerous observation holes that we observed and then closed up. George Smith: But you usually put a pipe in them. Deb Dunn: Not necessarily. Wade Saucier: There was no reason to do that because we saw the groundwater at that time. George Smith: Well the reason I say that is because that is what our regulations call for and I would think we would be working from them, unless we waivered that. 8

Wade Saucier: It is a debatable thing, I am not sure if it is the health agent s call or not, I would have to read the regulation. But during groundwater season I m not sure that you need to put a pipe in it to monitor, how many times are you going to monitor it. If you do it during groundwater season. I would like to talk to the Board about groundwater season. Deb Dunn: and also you observed no modling. George Smith: I was there. Wade Saucier: And the state was out there in August, so we have that on the plans. We have groundwater in February and August. We were looking for high groundwater and we found it. George Smith: Was there any mounding? There are usually adjustments. Wade Saucier: Yes, and it it s in there. The groundwater mounding for anything over 2,000 gallons per day. George Smith: Are the percs on the plan? Deb Dunn: We are not approving the plans we are approving the variances so the plans can be tightened up and submitted for approval. George Smith: I was concerned when we are doing the drainage and the septic and that we are following the regulations and that the tests were observed by this board as per our regulations. I think that is very important, so we have a standard. I understand that DEP did some and we did not get a chance to do them, or maybe we did..did you do the other ones outback? Wade Saucier: No, I did not do the ones outback. George Smith: Well our agents engineer is the one responsible for that according to our regulations. So that is my concern but I am not saying that it is something that we can t deal with. Deb Dunn: It s also on another parcel. Wade Saucier: And another application all together. George Smith: Well drainage is drainage. Wade Saucier: Effluent loading rates. This is a tough one, this is probably why Joe isn t here. Locally the loading rates, because it s a restaurant, nursing home, the waste water is at a higher demand. When these regulations were written bods were not really looked upon. The Board of Health can through effluent loading rates require different perc rate or a higher perc rate so the system would get larger, you have a stronger effluent the concept is that you need more square footage which is dealing with oxygen. The local regulation requires the field to be bigger, almost three times bigger. George Smith: If we use this Cultex, you are going to run a pipe down through it that will provide the air? Wade Saucier: I am not doing anything. This is why I am not appreciative of the applicant not being here because he cannot explain it himself. Deb Dunn: He is running the risk of our understanding, of not getting our understanding. Kevin Erikson: Mr. Peznola has done a ton of work for us, fantastic engineer, he would have been here if he could have been. I apologize for that. And I do think there was a lot of discussion about this particular variance at the last meeting and I believe he has supplemented that as well. George Smith: Well some things have changed since then. Isn t that right? Wade Saucier: The venting system has actually changed. George Smith: Are we spinning our wheels here? Should we wait for Mr. Peznola, so when we ask the questions he could answer them. 9

Wade Saucier: It is up to you. I can explain what he is proposing. What they are doing is providing more oxygen in the field. So you won t have to make the square footage larger to provide more oxygen. George Smith: That was suggested and I kind of like that particular idea, you don t have to make something to mechanical but science wise is it going to work? Who determines that? Wade Saucier: Looking at the variances and talking to the engineer, it was difficult for him to understand the regulations on how not to exceed the bod versus pounds per square foot. The original author isn t here and the regulations don t have an explanation. George Smith: If he were here I would be asking him how it works. I think it is important for me to understand, Wade Saucier: No one is expecting anyone to really know this, it is a complicated regulation. I called another town to see if they could explain the regulation. They gave a really professional response, saying that they rely on the design engineer and they trust their calculations and I take from that they don t know how to do it either. Talking to Joe, I don t know the mathematics, but it is done with bod, so another way of doing this is to increase oxygen in the field. And how would they accomplish that? He proposed one way involving two pipes but I said the Board of Health might like it if you have two venting systems. I am just giving advice to applicants that come into town for what the town might like. With the technology we have had over the years we have a high low vent that some companies may use. With the high and the low vent you have a flow. That is what they are proposing. We were going back and forth on the style. They came up with different options so that is where I got into helping with the design. George Smith: I was also looking at the distribution of these lines and it says in our regulations and they are supposed to have separate lines for each of these trenches, according to our regulations. Wade Saucier: This is a pressure dosing system. The field that you see on the plan is incorrect. This is not a complete plan. So there are a lot of design details in it but I am not going to spend any time with them until they can design for this particular lot, between the two zones. George Smith: Give us an overview of it but I would like to have the engineer. We need our professional people to oversee for the Board of Health. If we also have the engineer, he becomes the expert. We would like to have both experts here. Deb Dunn: I agree with that to a degree. Wade is our expert and it is his opinion that I will hold above the applicant because he is looking out for the town. The applicant s engineer provides the best face and product for the applicant. So the applicant has decided to move forward at their own peril, if their engineer cannot refute what our expert says, and we make a ruling on it then they own it. Evidently they were confident with what they provided, so the fact that the applicants engineer is not here is the applicant s peril, not the town of Wrentham s. Wade Saucier: I can explain what they are looking for relief, some kind of logical explanation. Deb Dunn: I don t think for a minute that Wade is trying to convince us to do something for the benefit of the applicant. He is not speaking for the applicant. Dr. Brian Kelly: Right, he is advising us because it is very technical. George Smith: The applicant comes forward with their plans, we have our expert review it, we look very highly on our expert to make sure that the health issues are being satisfied. Deb Dunn: One of the things I have seen that is positive from the last meeting is that you (George) had some serious concerns about air flow in the cultex chamber. Wade has had conversations with their engineer to alleviate the concerns of a member of the Board of Health. And I think that is a very positive interaction between the two engineers. George Smith: Do you talk to the engineers in your firm about this too Wade? Wade Saucier: Yes. Deb Dunn: He has a team. Let s hear about the grease traps. Kevin Erikson: The only variance we are looking for had to do with the width, the separation. 10

Wade Saucier: They increased the size of the grease traps, they want to cut down on the grease and the total suspended solids. They did this by choice. Deb Dunn: Now we are down to expansion area trench spacing. Wade Saucier: Title 5 requires 3 times the effective width or the depth whatever id greater for the reserve between the primaries. The local board wants ten feet and if you look at practically, at that site, if there is a failed system they are not getting into cutting up the tar, they will have to destroy the whole thing. The advantage of the extra four feet, I don t think is a major concern at least public health wise. Deb Dunn: any questions George Smith: when you say take the pavement. I want them to do this and I want it to last. Wade Saucier: Look at the plan, look at the leaching area and picture them replacing it. Deb Dunn: They are not going to do a surgical strike if this field goes bad. They are going to have to rip this whole thing up. They will have to rebuild, because it will be twice as fast. Wade Saucier: The reason why they are doing this, it s not that they don t like the ten feet, they are so tight with the Zone A on both sides, if the BOH likes, I am not here defending this plan I am just telling you whether or not this would work. I am not here pushing it on you I am describing what they are trying to do and saying yes its real, it s logical, it s a real concern. They are trying to put nine pounds of tomatoes in a ten pound bag. It is not the applicant s choice. Deb Dunn: They are constricted by the Zone A. Wade Saucier: If they didn t have a Zone A this whole thing would be tied into the treatment plant. They need to develop this lot because it s a grab lot, they need to use all the space and that is why they are here. But it does meet the state standard. George Smith: That venting system that they are using. Can it be vented in such a way so that they can reduce some of this Wade Saucier: That venting system is to placate the local board, because it s a commercial wastewater. If they use what Title 5 requires then it will fit but they are looking at the local requirement, which would require the system to be larger. If look at Title 5 the regulation is the same, the local regulation is a redundancy. With a larger system you get more breakdowns of organics. Another way of dealing with it because they are stuck with this area, is to add more venting. George Smith: We talked about the elevations, the elevations to groundwater. Where is that at? Wade Saucier: That I didn t even look at but it s on the plan. George Smith: What is your feeling about the ground water and the bottom of the soil absorption system? Wade Saucier: It should be five feet. George Smith: Five feet with a 2 minute perc, it has got to be five feet. Wade Saucier: Of course. George Smith: Has that been reviewed yet? Wade Saucier: I didn t even go that far with it because there is no need for it at this time. Deb Dunn: This is a concept that tells them that they need these variances. Wade does not have hard fast numbers until the variances are approved. Once they design it, if it fails to meet our regulations Wade will send them back to us. There is no way we grant these tonight and they get out of anything to do with Title 5 or anything with the local regulation that we haven t given them to right to do. We are only talking about variances for these issues only. George Smith: If these are the variances you are looking for why can t you engineer it to comply with our regulations? They are over building for this lot. Whether it is a signature lot or whatever it is very very tight. 11

Wade Saucier: You are correct but I am not the applicant. They chose to design a system that requires variances. George Smith: I am wondering how much of this tank will be in the water or are they going to build that up? That is why I am looking at the overall plan. Wade Saucier: I didn t look at that close, it is not above the road. How much fill they put in there, I am not sure. There s no break out, everything is flat. It is not a high system. George Smith: I was concerned because there was a house there at one time. The septic system was in a particular area. I know there was water flowing though it and it was an issue. Wade Saucier: I don t want you to feel like I am working for the applicant. I speak to homeowners, commercial applicants, and I give them advice on how their permit should be addressed to help them through the process. I am not pushing this plan through. I can explain regulations and then he says what the next best thing is. I am not here to push these plans through. George Smith: I find it difficult when you recognize situations for what it is. I know how important it is to get the most of every square footage there is. Having traffic problems, having more buildings on the lot, I understand. I have worked on the other side of these things, and I am probably going to go to the next Planning Board meeting. Deb Dunn: We are here to discuss septic variances for the project. George Smith: Well what do you want to do? Go ahead. Deb Dunn: I want to find out if the applicant would like to give a closing statement and we will close the hearing, we will discuss it some more and have a vote. I respect your opinion, It is very hard to take your focus away from the big picture to the section of the picture that we have the authority and the trust of the people to work on. I am not saying that those two don t overlap from time to time but I think we are going a little far afield. Would you like to continue? George Smith: It s your meeting. Kevin Erikson: I appreciate the board listening this evening. These variances inform the next steps, so that we can move forward with the design, we are working with a tight site, and the Zone A is an issue for us. I think we have worked hard to mitigate to the extent that we can the impact of these variances. I apologize that the engineer is not here, it is not in his character to skip a meeting to avoid a hard discussion Deb Dunn: I close the public hearing. Dr. Brian Kelly: Wade could you summarize what your recommendations are? Wade Saucier: The variances are for local regulations only, the system meets Title 5. The depth and the tank size will give you the hydraulic retention that is required by the state. The 300% is there, which is a local regulation. The field is a Title 5 field, it does not address the commercial waste, but he did double vent the leaching facility to see if the BOH would agree to that. Also, I think he is encroaching a drainage less than fifty feet but that is not encroaching groundwater. George Smith: Where is the drainage? Wade Saucier: 11 o clock up on the plan. Deb Dunn: They were going to encase the drainage, so it s not a leaching basin. They are going to seal it, they are going to tar it. It is piped drainage, it s not a leaching basin. It is going into the rest of the drainage. Wade Saucier: I am not sure where the drainage is because I am not part of it. George Smith: The drainage is part of the whole process. Deb Dunn: It is being done by PSC, which is the company Wade works for, it is not carted out to different groups that aren t speaking to each other. 12

Dr. Brian Kelly: I make a motion to allow liquid levels of 8.5 feet for a 9,000 gallon tank and 11.2 feet for a 12,000 gallon tank. The second is on the effluent loading rates, the variance request is from the LTAR loading requirements. Also, a variance is requested to allow spacing of 6 feet in accordance with the provisions of 31-CMR 15.251(4). Deb Dunn: Would you also include the withdrawal of the perc test variance. Dr. Brian Kelly: Yes, also withdraw the first variance on percolation and water table data. Deb Dunn: I second the motion. Two affirmative votes, one negative vote. The motion passes. George Smith: I want it on the record why I voted no. It needs additional information. There is not enough information.
