 more apt to crack and save steel. I can't speak to the engineer, but I can't speak to him just that. When the tank arrives and is placed in the hull, the fire department will inspect. And then we do tightness testing at that time. And then we tightness test all, or witness all the testing of all the piping. And then when it's buried, we retest and test again after it's buried so that as ground is compacted around it, to the extent that we would expect it to move, we test again to make sure that nothing has moved. Once you get beyond that, I think you're talking possibly a cataclysmic event of some sort. A cataclysmic event? A cataclysmic event? Oh, yeah. When you're shifting the soil, all bets are going to be off. Ultimately, although you might be able to speak better to this, some tanks do move through events to floods like that and do not rupture and do not leak. Okay. The other thing is, you said a leak was detected. Was that contained within the outer wall? Or is there going to be contaminated soil too? No, that leak was they found water in the space between the two tanks. Okay. Two walls of the tank. Okay. I'm done. Thank you. So if you could speak kind of generally to the increased incapacity and whether that would represent a particular new safety threat or not. I don't think it would represent any more of a safety event than was currently there. It increases the amount of product there. There would probably be fewer deliveries. Correct. Decrease the amount of, the real hazard is really driving the truck down the road and putting that product in the ground. So if you decrease the number of times that that occurs over time, you're actually decreasing the possibility of some kind of incident when that product is moving from the truck to the ground. Thank you. Other questions or comments from Select Board? Mr. Hayden. Yeah, a whole bunch of stuff. I mean, clearly, you know, this seems like it's ginormous and then there are kinds of concerns that we might have. I'm very familiar with this double wall system, having installed a number of them over at my place of work. I don't know if you could briefly explain how it's built so that, for instance, if the ground were to shift, that it has no impact at all on the inner tank because of the interstitial space between them. Number one, number two, how that space works to, you know, pick up monitoring and other problems with all the sensors on the bottom. And third. Check, check, check, check, check. All right. It works. Planning board and places. Check, check, check, check. Oh, it's fine. But do you sit here? I thought you'd check. Yeah, I will. I'll give you basically a five-hour-long dissertation on the safety equipment. But basically, these are, to really simplify it, a double-wall tank system. And what it is is exactly what it sounds like. It's a fiberglass tank wrapped by another fiberglass tank. And there is a space in between those two tanks. It's called the interstitial space. Hess prefers a hydrostatic interstitial space. And what that means is that there's a brine in between the two tanks. It's bright green. And when they set the tanks level into the ground, what they do is there's a reservoir on the top of the tank. And the brine is basically set. That doesn't change. And that's monitored 24 hours a day, seven days a week, 365 days a year. And what that does is if their brine level shifts in any way, whether it goes up or whether it goes down, those monitors are very sensitive. They will pick up the shift in the brine, which means a couple of different things. It can mean that you have a breach in the inner wall of the tank and that can mean either brine from the interstitial space is making its way into the inner tank or it could mean product that is in the tank and the inner tank is making its way into the interstitial space, which would make the brine rise. What we think happened at the tank today was that groundwater was making its way into the interstitial space. And the same thing would happen if that happened with the new tanks. So brine and the reservoir would rise because you'd have groundwater making its way in. Or if there was no groundwater present, the brine would leave the interstitial space and that reservoir would shrink. So that will basically detect any release of product or any breach in the inner or outer wall of the tank. You also have overfill prevention devices on the tanks, basically set at 90% capacity and another one at 95%. So gone are the days of your fuel delivery vehicle driver comes, hooks his hose up to the tank, he's dropping his product and he goes and decides to have a conversation with the attendant. The next thing you know you've got product making its way out of the tank onto the ground and ultimately to wherever it goes. At 90%, what will end up happening is some valves inside the tank will start to shut off the ability for the driver to drop product into the tank. Alarms will begin to sound. There's an audio alarm, individual alarm at the area where they're fueling. You also have a 95% sensor on the tank so that basically what that will do is whenever the driver's dropping product they also have to take the vent or the vapors out of the tank back into the truck. At 95%, there's a valve that keeps the vapors from being able to be displaced from the tank and obviously you won't be able to put more product in if you can't get the vapor out. So there are fail-saves in place regular to being able to overfill the tank. You also have other devices, buckets on the ports where product is either being introduced to the tank or vents or vapors are being taken out to help again any condensate that may be created will make its way back into the tank. There are bells and whistles on the product piping so that if there's a breach in the product piping basically that's the line going from the tank to the dispenser. The product will be shut off. You won't be able to get product from the tank to the dispensers. It'll first slow the distribution of product but if there's a big enough breach it'll shut it off completely. The dispensers are fit with protection devices so that again you've probably all seen in movies so if he drives in and hits a dispenser knocks it over and you get product shooting out of the ground you don't have that anymore. You have sheer valves both on the dispenser and the island so that in the event the dispensers displace the piping is sheared off and basically you get very little product that'll make its way into the environment. The hoses are fit with similar protection devices so that in the event someone happens to drive off with the hose instead of getting a major release of product all they get is a bill when they're picked up on the video camera but really it's a state of the art system and the chief or assistant chief's office will have an opportunity to review the entire set of plans if we're approved we have to submit underground storage tank installation permits and removal permit applications with the fire department and that's where we'll submit I think it's about an eight page set of plans that outlines all the bells and whistles and to your point relative to a major event if you had an earthquake never been asked a question I wouldn't vouch for anything if you had a shift in the soils like that these tanks are designed they've got couplings of one that they are designed to fluctuate a little bit there's going to be some settling or you might get a little bit of lift in the tanks but these things are set with dead men which are basically concrete pie or pier a lot better term laid on their side so I hold the tanks down there's an eight inch concrete mat over the top of the entire tank field so these things are designed with the intent that they are empty and set in water so they're not going to basically move once they're set they're pretty much where they're going to be again maybe some microscopic movement but nothing that should result in an issue where we need to worry about the differences between steel and fiberglass fiberglass reinforced plastic tanks which are what are being installed here basically again the industry standard and since 1994 I've probably I would guess designed and permitted probably well over 500 gas stations throughout New England and that's pretty much what everybody's using is not only here but across the country as well thank you you're welcome any further questions Mr. Heen? maybe one so we're increasing the capacity by 70% that's just to me that if delivery can't be made we have 70% more capacity to deliver if the road should be closed for whatever reason would you say the road should be closed yeah I can see what you're saying and to further review the system Chief said that is one of the benefits of increasing capacity the site is you are going to limit the amount of fuel deliveries on site and every site is different it's based on demand but this is a fairly low demand station compared to others in the chain and also has indicated your biggest opportunity to have a problem is when the fuel delivery time is on site drop the product so reducing the amount of times that tanker is on site ultimately reduces the amount of times you can have a problem any questions or comments from the select point? I would just note for the record that the application has been reviewed by both the fire department and the inspection services department and recommended for approval thank you any other questions or comments before we go to public questions or comments? alright anyone from the public like to comment on the application? alright then thanks for reading I'd move to close to public hearing is there a second? second one say aye alright this unanimous then deliberation by select board very easy Miss Stein would you like to make a motion? sure I move that the select board approve the application of test corporation Woodbridge New Jersey relative to the removal of three existing single walls steel underground storage tanks USTs an installation of two new 20,000 gallon double wall fiberglass underground storage tanks at their express gasoline facility located at 468 West Street Amherst MA granting an amended fuel storage license increasing maximum capacity underground from 24,000 gallons to 40,000 application presented by LMD Stefano from Bowler Engineering second for the discussion I would just note that I appreciate very much the information that you gave tonight as well as all the information in the packet I appreciate very much Assistant Chief BK attending and talking about safety issues with us support us good questions and the fact that this has been all reviewed previously by our inspections department and the fire department is much appreciated and the recommendation is appreciated I will note for folks at home that a butter notices did go out to everyone in the neighborhood everyone required so and no one did show up to express any concerns about this nor did we receive comment previously and by email or call us to select our office so that's all I have to say other comments all in favor say hi hi hi hi hi that is unanimous thank you very much for coming in thank you you will we'll leave those a few minutes thank you very much appreciate it probably mentioned at the beginning when I wasn't here but it was incredibly helpful to have that information that town staff asked thank you all right so the other items on our agenda just so select where it notes the housing study summer meeting schedule were carried over from last meeting just in case we didn't get to them at that time because the agenda was posted prior to that so we're done with that we do have on our amended motion sheet or rather our revised motion sheet a couple of new issues a special license as well as some committee appointments this time I'd like to make the motion I moved at the select board through the application of Denver snow on behalf of new parent restaurant catering 1-1-2 north main street Sunderland MA for a wine and all special license for a rehearsal dinner to be held at Eric Hall Museum in Amherst Saturday May 12th 2012 from 6-9 p.m. Kendra Nielsen event manager contingent on approval of the Amherst lead department we can actually strike the last part because we have since received the approval of the police department so it's no longer contingent there's second they were saying why we have appointment I move that the select board approve the appointments of Greg Studsman and Aaron Blodgett to the housing and shelter committee for a term to expire June 30th 2015 second for the discussion I just want to note that it's not unusual to have folks serve on committees who live out of town as is the case here that's a good point, thank you very much Ms. Brewer and have resided, especially that have resided here in town previously and I also just wanted to say clearly people do occasionally listen to our meetings because both of these met the criteria that we were looking for to fill those final two slots thank you to everyone who talked to everyone and who listened to our meetings from the discussion all in favor say aye aye all right other issues the only other thing we have to do tonight is to have an executive session so and we are going to be meeting again Monday night so I don't think we have any logistical issues related to town meeting currently Mr. McSanthe actually want to give us an update on article 29 and the status of that I have received from council a draft version of modifying the petition as submitted into a resolution form and that is going out to the petitioners and expect to be getting good dialogue and feedback and be in a position to have something in your packet before the weekend for your Monday meeting we hope you can take a position on this and I will be back to you other key information updates from town manager or select board nothing that can't wait until Monday okay I want to make sure is this gentleman here for anything on the agenda that I'm not expecting you can come to this but thank you so much for volunteering to be part of that so we appreciate your service very much alright anything else before we adjourn to executive session I'll make the motion I may have to go into executive session per chapter 30a section 21a section 3 to discuss strategy with respect to litigation regarding the landfill solar project lawsuit as an open meeting may have a detrimental effect on the litigating position of this public body and open session will not reconvene at the conclusion of the executive session I will call vote Mr. Wall Stein I Keith I Hayden I and thus the open session of this meeting adjourns at 6.57pm and we'll see you again on Monday thank you
