008getting the funding so um I think I hope that Source uh needs to be could be reconsidered nonetheless a resolution to support city council funding a phase 2 feasibility study on municipalization is a positive step forward on the road toward possible municipalization so I support it and hope you will also thank you very much thank you thank you a are there any other callers I don't see any other cols with their hands raised great um with that I'm going to move on to um what we have labeled as new business but it's actually very very old um and we're fortunate to have two speakers who are very qualified in addressing the issue of the galman plume um which has um a status as being close to being listed on the national priorities list of the

009EPA I'd like to introduce first um Dan bnell who's president of Global Environmental Alliance who discovered the contamination 40 years ago um and whom the environmental commission has plotted with um recognition for his ongoing work to support clean water for the city of an arbor and surrounding communities um so Dan thank you for being with us tonight and um I would be very interested in hearing your comments sure um maybe eron we could pull up part of the presentation or the presentation sure yep I imp PDF so let me um we can get started and I will I'll pull up the uh the PowerPoint yeah the PDF would be fine oh okay sure um well maybe it's best to start with uh you know what is super fun we've all talked about uh how the

010federal government can come in and help us with this Gilman dioxine plume that's been moving around um if we go to the next slide please um what you see is that um the comprehensive environmental response compensation and liability act which is commonly called cira and known as superf fund was enacted by Congress and it was about 1980 when they had problems with Love Canal and the uh cira was there to address the dangers of abandoned and uncontrolled sites but the the law does is it creates attacks on chemical and petroleum Industries and provides very broad Federal authority to respond directly to releases or threaten releases of hazardous substances that could endanger Public Health in the environment and in the federal superf fund program where this money is used there's two components of it there's the

011side that actually has the money the super fund and it's used to clean up a toxic waste site where there's not a viable polluter who caused the contamination however there's a second side of it and that's where probably Gman would end up and that side of the program is super fun enforcement where the requirements of cira are placed upon the polluter they're called the potentially responsible party and they then uh are required to spend their money to do a cleanup and the Superfund program in the enforcement Branch works with the Department of Justice the US EPA office of Regional Council and they require that the potentially responsible person enter into an order with them like a consent judgment if you will to perform the work to US EPA criteria currently about 70% of all the

012Superfund sites are super fund enforcement lead sites where the government works with the industry uh through this administrative order to have the industry clean up the site if we go to the next slide um what happens however is if this potential responsible party does not agree to expend their funds and enter into a Circa administrative order on consent the government will issue them a unilateral order in other words telling them this is what you must do and if they refuse to do it then the superf fund money will be spent on the cleanup and at the end of that process the US EPA will bring a circle cost recovery action against the polluter uh and recover the money spent on super fund as well as the administrative costs incurred by the agency uh currently uh

013they have obtained about7 billion in cost recovery actions against polluters who refuse to do what is asking them to do for us at the Gilman site uh we have a viable potentially responsible party who can pay for the remediation Gilman was acquired by Paul Life Sciences which is now a subsidiary of danaher Corporation and as you all I think know danaher is a multi-billion dollar corporation uh cira holds current and past owners responsible for mediation of the site so it's quite clear that Gman is responsible underneath uh circles underneath the Superfund program to remediate this site if this becomes a uscpa Superfund Site um if we go to the next slide a little bit of background uh this Gelman site has been a listed Michigan contaminated site since 1988 unfortunately the dioxine plume continues to

014move in high concentrations toward sco Township residential Wells and Arbor Township residential Wells the city old west side City West Park and Barton Pond which as most people know uh is where we get about 85% of the city drinking water the eagle has made numerous Promises to the community to improve the remedy but that's not been able to occur in court and currently we have a 2023 fourth amended consent judgment in other words it's been changed four times from originally back around 1990s uh and it still is not constructive recent studies in Scio Township and anber Township have shown that the plume has now polluted approximately 43 residential Wells and it's getting closer to the hon river which again supplies about 85% of the city drinking water the Plum's moving in Northern western eastern and

015southern directions and it doesn't really have any effective offsite control I have a figure here which shows where the plume is uh you can see uh the nice colors thanks to Roger rails uh figure here and I've put uh some indications of where the sciot township areas are where the an arbor Charter Township areas are that have residential Wells and the plume is again moving in a north and an Eastern Direction currently it's about four miles long and two miles wide and as you can see there are very high concentrations in this plume the drinking water criteria for the state of Michigan is 7.2 uh but uh the plume has you know a th to 2,000 parts per per per billion in it uh which is which is not good for any of us if

016you look at the second figure that I've provided this shows again the plume but it shows the fourth amended consent judgment extraction wells in yellow where they're located but importantly it shows in these blue arrow indicated areas where the dioxine plum is already past these very limited uh extraction Wells and moving freely to the north and to the east which is again towards the S Township and arter Charter Township and Barton pun uh so this is not a good situation these Wells have been uh there for quite some time but they're very ineffective and that's what allows the dioxine plume to continue to migrate uh further away from its core areas if we go to the next slide again what we're under is a state order currently and that's the four amended consent judgment and

017it was entered into in 2 after much discussions however it allows still the migration of the dioxine plume in all Direction uh stopping this plume from expanding and that presents again a risk of Municipal Water Supply hover private water drinking water wells building occupants from Dio Vapor intrusion and workers in a trench who are in contact with this shallow polluted groundwater uh the amended consent judgment essentially allows for the taking of private property owner rights to use their well rather than halt the dioxine plume and preserving the aquifer so the land owner can use their well what happens mechanically is because this consent judgment does not stop the plume from migrating towards the township and residential Wells it is contaminating these cont these Township Wells and leaving them with no real alternate water supply uh

018what should really be done in these cases uh is that uh the plume should be stopped and therefore preserve the ability of the property owner to use their uh well for drinking water if you go to the next one please and this speaks really to what uh we're here about this is the status of how us where USPA is um to give a quick history uh the townships and Sierra Club filed a petition with usca to conduct a preliminary assessment in 2016 the objective of that was to determine whether the Gilman site may be able to qualify as a US EPA superfunds site uh and what was found in their conclusion in November 2017 is that it does qualify however uh we had to wait a while uh to get a concurrence letter from the

019governor saying that she would support in this case a US EPA super fund fight and that occurred on April 12th 2021 on December 23rd 2023 uh EPA completed some of their important work which is which includes a site inspection and the site inspection and a hazardous ranking score concluded that the Gman site does qualify to continue the process to be designated as a USA superf fund site in fact on March 7th uh they announced in the Federal Register that USA intends to make the Gman site into a US EPA super fund site commonly called the national priorities list site and they requested that we provide comments as a community on whether this should occur or not currently there's a 60-day public comment period that's open it closes on May 6th um and what will happen

020is when the USA receives these public comments they'll review them and make then a final determination on whether the Gman site should be a USA super fund site or not if uh people are inclined to make comments one way or the other uh this is the link that they could uh use and if you just look under the browse document tab you'll see uh where you can add your comments this should be a designated USPA Superfund C or not some of the questions that come up are what's the benefits of a US EPA Superfund Site and in the next slide uh you see that what uscpa will do is from similar USPA sites where they've had these type of solent problems is they would actively restore the aquifer to drinking water criteria they would at

021first extend the municipal drinking water supply to any Resident who may be potentially impacted by the plume they would halt the expansion of the plume and do and by doing so they'd prevent contamination of Barton P they would require a full monitoring Well Network to establish the breadth of the dioxine plume which is not known at this time well and they would establish a comprehensive drinking water well sampling and analysis program using the best uh scientific analytical method that they have at the time if this becomes a uscpa super fun site they'd also offer a community Grant so we could have input into the Superfund Site cleanup process they would use the technical administrative and legal resources uh to EST protective administrative order again restoring the aquafer pting the plume and this would uh be

022overseen by the United States Department of Justice and the office of Regional Council U importantly this United States administrative order which would be the federal order that they would give to G would replace the current state fended consent judgment so essentially the US EPA would start with a clean sheet of paper uh work with Gilman to establish an administrative order for Gilman to do the work which would be overseen by uscpa the Department of Justice and officer Regional councel and they would in that administrative order ask Gilman to restore the aquifer uh provide a municipal water where is appropriate and take active to the aler uh to drinking water criteria so that's kind of the Seven Mile High view of what Superfund circle is all about and the benefits that one would have if this

023was a Superfund Site this is a flow diagram of uh what we've been going through for the last eight years here since the preliminary assessment in 2016 uh you see on the left that a preliminary assessment is done is the Hazardous ranking score over 285 it has been you do a site inspection which looks at soil groundwater issues you then revise the Hazardous ranking score and if it's over 285 then you go on as usepa excuse me has done to say that yeah this qualifies to become a super fund site and we're seeking your public comment on it it should be noted that the Hazardous ranking score is was 50 which is the highest you can have for groundwater because of all the potential receptors we have here to this dioxine contamination so that's that's

024where we are in the status of US EPA uh working towards making this into a national priorities list super fund site thank thank you Dan um I'll ask the commission and just say that we're we're g to try and keep on track for time just want to call that out but if there are questions that the commission would like to ask um Dan bnell at this point I would like you to ask them m Curtis So after the public comment is closed do we know when a decision would be made it'll take probably three or four months commissioner for them to make a decision because what they'll have to do is they'll have to look at every comment and they'll have to provide a response to every comment and then they'll have to make a

025final determination of whether yes this should or should not be a uscpa Superfund Site Mr Brown yeah thanks Dan um it's long overdue but um I just had one question and that is is there are there any current examples of contamination sites um that are undergoing cira treatment for dioxine one4 dioxine and um does that do they give us any indication of how long it might take to um to amend uh amend the plume as it's uh progressed so far yeah there there are many sites that that have solid and contamination like the dioxine all about including forign Michigan and the classical technology that they've been using is really to its groundwater extraction and treatment which we have out here very limitedly so if EPA came in likely what they would do is they would

026expand the number of extraction Wells to capture control this plume uh because the plume is so big uh it will take a long time it'll take 20 years you know for this to be halted and remediated to drinking water criteria at least if not there are larger sites this are dioxine contaminated matter of fact there's one out in Beth New York that's about eight times as big and they're doing groundwater extraction and treatment the other thing that they are talking about is com metabolistic U where sorry to be overly technical but bior remediation where you inject a chemical which will be easily biodegraded and part of its biodegration it will start chewing up bits of the dioxine they call that com metabolistic bio remediation because it's two things working together but that's not uh coste

027effective uh in a situation like this this the most costeffective and this has been going on this is nothing new you know when I worked with the agency back in 84 we were doing groundwater extraction and treatment classically so this is a classical problem unfortunately we have a polluter who refuses to do the proper thing and after 40 years uh find I think we're going to be able to get some federal support to help push them along or if they refuse to do it just uh spend the super for money and do it in assing cost recovery yeah thank you missioner nadri uh if you're speaking Sarah we I think you're muted that's so funny sorry hi thank you Dan that was really interesting um I just was um wanted to take a step back

028and think a little bit more about like the amount of Technology involved in taking such a massive groundwater plume down to drinking water level um from what I've seen that is a really really challenging thing to do um and it also is you know very very expensive so I just kind of wanted to I guess put out there that you know what I've seen as far as EPA and super fund um is yes they can they can require more cleanup out of a liable party but to get down to that drinking water level that is going to be really hard um and it also you know I think a more reasonable goal is to prevent the plume from expanding which it currently is as far as we know doing um and preventing it from getting

029it to Barton um so just kind of setting sort of like a realistic expectation I think is important um and I guess another question I have is um what happens legally um to the consent decree when super fund takes over I'm assuming that consent decree doesn't just disappear because it's you know it's based in the courts um has the city like looked into that or are you involved in those conversations Dan do you have any knowledge of that yes Sarah um the on your first question actually it is quite easy to get down to the drinking water criteria 7.2 and it's done all over the place including the four sites in Michigan um it just takes time it takes time to do that and so again the USA objective is to Halt the plume migration

030and restore to drinking water and they been able to do that uh all over the place using groundwater extraction and treatment when I was a US EPA super fund enforcement officer and in underneath the circular program in 1984 to 85 we did this all the time and it continues on it's just classical treatment technology that can easily be done it just takes time and money um what happens with this consent judgment it's a state consent judgment and what we'll be doing is we'll be going for a federal administrative order and the federal administrative order will will if you will Trump the state consent judgment so the state consent judgment goes away there's no uh requirements for Gman once they are receiving and agree to an administrative order uh that they have to follow under underneath

031the state consent judgment it is set aside okay well I I definitely hope that right and um I love your optimism um thank you for that response but it's not but but but it's not optimism those are the facts uh the the federal the federal government uh administrative order will supersede the state consent judgment now a lot of the elements that are there right now such as continuing with the groundwater extraction and treatment that's being done underneath the state order will be probably included in the administrative order that the federal government gives them under under Circle okay so they're not just going to tell Gilman well just wait around you don't need to do anything there will be a a seamless interaction between the work that the consent judgement under that the state is asking

032them and what the federal government will ask so there won't be any laps in time when nothing is going on at the site or no active remediation is going on at the site that active remediation even though it's very limited would continue underneath a a US EPA administrative order makes sense thank you welcome all right thank you all um any other questions if not I would like to introduce Roger rail who's the chair of um citizens act active for remediation of dioxane or card and is also chair of the Scio residents for Safe Water we've as an environmental commission have also um commended Roger for his long dedication to following the data and speaking up for clean water in the community um not only in his immediate area but outside in the whole city of

033an arbor and the townships so um Roger thank you for your ongoing work as well and um I know that you have a a short presentation for us and I'll appreciate viewing that thank you and hello all uh couple people on the screen I haven't seen in a while so that's good to see you um it turns out that the way this uh Zoom is set up I can't can't share my uh my screen I can share uh windows so I'm going to have to switch Windows I'm starting off with the the one that I use to create a lot of the images this is a Google Earth matchup but I'm going to switch to um what's basically a set of slides that I had uh prepared so let me get this ready to go

034and didn't do my switch over here on new share here's my screen mine's going to be really quick uh thanks Dan for the excellent overview of the super fun and and and the Cirus uh process and and what's going to happen uh as this proceeds and and this can be cleaned up it like Dan said it's going to take a while so this is what's happened uh over the last uh 31 years um we've got a map by the way these maps that I produce any of the colored portion except for the yellow is is based on Gilman Maps themselves so you can see my cursor all right I presume yes so this is the plume in 1992 the first one of the first uh total plumes that we Mar that we had and you

035can see the size of that it was already expanded into the Evergreen area which was at that time in s Township and sense had to be annexed to the city order to provide water and this is where it all came from the Gman property in this lower corner here and then we jump to 2023 this is where the plum has expanded over those years because it hasn't been first defined enough to uh know where all the dioxine is to go and intercept it but also because of the the amount of cleanup was not what was needed so uh 31 years of cleanup we went from this to this so it's really time for an EPA enforced cleanup because the EPA has the enforcement capability and uh something that the state hasn't been able to do

036all these years this is a close up of the two 2023 and um this offshoot to the north is a surprise this is these are the sampling that s Township did and even there's one hit that was brief at an arber Township and then the orange Donuts are where the state came in and resampled those sites and found most of them they would have found all but the state doesn't use the same uh best available uh analysis method that the township used so like Dan said there's about 40 some hits some of them are a lot of them are right here to the north right out of the Evergreen uh offshoot uh near 465 dep Pont there's some that are in uh Elizabeth Street that have been going on for years there's a new hit

037here next to the KFC property that's going to be developed and there's one over here on in breezwood that uh is now solid hit these other Donuts are where dioxine has been found over the years uh this on Google Earth is actually a four-dimensional display where you can watch the hits as they occur over time now this is a similar uh map but overlaid on it is Eagle's rockworks model that they created in uh 2020 and the area that they were studying is shown by the white rectangle and it pretty much matches the high concentrations that were shown on the Gman maps in the previous one here again these uh everything the yellow is where I've outlined where dioxine has been found and everything uh the tan and all going to red and purple those

038are actually from gan's own maps that I extruded up to show the 3d effect etc etc in the I've superimposed on here uh Eagle's rockworks map to show that it's you know that covers pretty much the whole area there's a few places where there's not enough data to show the model can't really say what's going to happen in those areas and that again points to the lack of good data to know where the dioxine ends which way it's going and this part here ites completely missed this is almost a mile north of the boundary and it's only less than a half a mile from my house right here so I can see this coming and I'm in the same aquifer as these Wells are so after 30 years um it's time to get the proper

039cleanup done so there's more information at srswor and at this point I will stop my we stop my share briefly if we need to go back to anything else I can bring it back up again and then we'll take questions thank you Roger that was great I I think there's nothing like really seeing it in a in a diagram in that way so I appreciate that it's even better when you look at it interactively two or three fours right yeah so um Commissioners are there additional questions for Roger okay well I just want to say that when I see the the comparison from the 1992 to what is it 2023 it is really as standing the um expansion and during that time there has been treatment going on and so um it's really frustrating to

040see that and to know that things could have been done um so with that um I want to just ask Erin um to put that slide up that we talked about that for anyone who wants to uh capture this information and we can send it certainly to the commission as well um the which um Dan had displayed earlier this is how to write to the EPA on the um website and I highly encourage you to do so and to share with people um you can use the link that's displayed and there's an arrow that shows that you're supposed to go down to a box that's called comment on the on the there's a a page gosh I can't even see that um called browse documents and then click on a comment button Ain was pointing

041those out um I think it's really important that we show the EPA that the community has um concerns and um we have information that we can give them as well and um I want to just really thank the um um Roger and Dan and all of the volunteer people in our community as well as the professionals who have tracked this issue for years and years um and stuck with it it's been a really hard problem and um prevention is like our best friend um so we need to keep that going um Roger I see your hand what's up yeah just a couple more things um uh I'll share my screen again here so on srw um you can go to this feature section and you can click some of the links here and get some

042background information as well as direct link to make your comments that's just another way they did it and all the same images that I showed are over here on the right if you want to look at it in more detail that's great so you can have reference information at your fingertips and pull that into that's right we try to keep this up to date with breaking news and there's a lot of history too you can always go up here to the the search button and look for certain terms and find things from 20 30 years ago okay great so that's srswor right srswor um right there yeah um thank you but I I I got to give you some other news because um I I got the all the references sent to me today for

043this npl listing um and it's very good it's very complete I'm really impressed with how complete the EPA has put together all this stuff in what's really considered to be a short period of time uh it doesn't have it all because we have some locally here that you know needs to be contributed but we can do that over time so it's it's really good that we have better information and better organization of the information and the whole idea of card was to help with that to have all the local stakeholders contribute what they know about this site and keep everything up to date so that all of the decision makers have access to all of the relevant information instead of having to go and dig for so that that's the last point I want to

044make and that and it's going to make this Superfund Site easier to clean up because of that because we have a lot of active people on the ground and and concerned and and the local governments and all the all the player all the stakeholders are on board with this so let's get this done and uh and Beyond with it so thank you thank you both Roger and Dan for your long service to the community to our water that's so important all right so I think we will move on with our agenda um and our next speakers are from the Michigan Department of Great Lakes uh oh Eagle the first one environment Great Lakes and energy please excuse me um we have Andrea Munoz Hernandez the district supervisor of remediation and redevelop re remediation and Redevelopment

045division from the Jackson office um and she has um finally um gathered information to talk with us about groundwater contamination other than the Gman Flume um here in an arbor and these are important things that are are part of our community and certainly I appreciate the work of eagle in in addressing them and it's really um helpful to know what's happening right outside our doors thank you Andrea and staff who are with you and I hope you'll introduce them so as you mentioned my name ises I work for the Michigan Department of environment rels and energy I'm the remediation and Redevelopment supervisor of the Jackson office so we cover five different counties washt is one of them and I have with me several project managers I mean they are the experts they today people that

046are working on these projects so if you have questions they are actually like people that can be you have more details about the questions that you may have I also have with me the project manager of the calan sit r b so if any of you have any questions or any clarifications associated with this side we're more than happy to provide any additional information um and with being set so my the size will be presenting and even though this theme is associated with one contamination there are other Pathways associated with Vaper intrustion they will be actually covered by different projects in here so we will have um Chris matthewson he will be presenting about articles Ashley leser will be presenting about the a former MGP uh then why will'll be talking about Armen and again

047Chris is here if anybody has any questions associated with thanks and quick question so Erin are you gonna be like sharing your screen with the slides or should we just kind of like each individual project manager share theirs yeah happy to do whatever it is easier for you guys is that okay with you Chris asley and then or I don't know how to share my screen here F by we use teams guess that answers our question yeah happy share sorry I probably could figure it out but I I am I am slow to the zoom crowd as well but I am semi functional so here we go got get that Zoom training uh yeah hello everyone my name is Chris Matthews I am a Environmental Quality analysis here at Eagle uh I'm the project manager

048for Argus I should say I'm overseeing this this site as it is a liable party site uh so Eagle isn't doing the investigation directly but uh I uh you know look at all the reports and talk to the liable party and their consultant uh next slide so this is a little overview here uh we call it the Argus buildings facility uh because there's two buildings associated with the source uh Argus one and Argus 2 uh this is located in the old west side of an arbor uh as you can see it's mainly residential in the area uh there is a elementary school Bach Elementary School to the South here though I will Point that's like upgradient of groundwater flow uh and it was uh sort of investigated early on uh you can go to the

049next slide so a little background here on Argus uh they manufactured Optical and photographic equipment uh between 1931 and 1963 uh they actually had a variety of industrial processes using lots of different chemicals however the main uh processes associated with the soil and groundw contamination we are seeing in the area uh were Vapor degreasing uh and chrome plating and that's mainly chlorinated solvents and then additional to that uh they had some underground storage tanks which were which contained fuel oil uh that was used up until 1982 and so we're also seeing some petroleum impacts in soil and groundwater next slide thanks um this is kind of just overview of the area again uh uh these green lines here represent uh the Allen Creek drain uh so it's just kind of an illustration that there is

050a storm water convence underneath Argus one I'm sorry Argus 2 uh and there's also sanitary lines and things like that that sort of run parallel so those are some of the preferential Pathways we're looking at or the liable part he looking at um you can go to the next slide so a little bit here on the chemicals of concern uh for chlorinated solvents uh we have pce tce carbon tetrachloride and they sort of breakdown products and then there's also petroleum uh products which are related to the fuel oil tanks next slide thank you um so the current status of the investigation uh as I mentioned uh there's liable party here it's ozam salvania uh there consulted as Geo Tech um and they uh so initially soil and groundwater contamination was found on Argus 2 uh

051Argus 2 is actually owned by U ofm and so they were doing investigation related to the fuel oil tanks because they are the reliable party for that particular contamination but at that time they also discovered coronated uh contamination and that sort of brought in the new liable party uh and then more recent sampling by geosync has confirmed that uh Argus one is a source of contamination uh previously it was kind of unclear if it was migrating from Argus 2 or not but there is extensive soil and groundw contamination on Argus one and so there it's also a source uh and the ground contamination has migrated off site though the extent of that contamination uh is not currently delineated so we don't really know how far it's gone uh that investigation is still ongoing uh so

052when we think about health risks we usually think about it as exposure Pathways exposure pathway is the way a person may come in contact with the contaminant uh so in this case Vapor intrusion is sort of the main pathway of concern uh so the chemicals uh that or the contamination we're seeing here uh has a potential to volatilize or turn into vapor and uh enter buildings or homes uh that's both the chlorinated uh contamination and the petroleum contamination though petroleum contamination tends not to travel as far uh there have been some mitigation systems installed in homes in the area um north of Argus 2 and uh currently uh east of Argus one some mitigation systems are uh being um they haven't been installed yet but they're in the process of being installed uh so the

053drinking water pathway uh the city of an arbor is uh supplies municipal water in the area so that's not directly an issue uh here um and uh there's also the groundwater surface water interface pathway otherwise known as GSI um it's sort of uh you know under investigation I mean the Heron river is about a mile north of here uh and as I mentioned the alen creek drain does I put Argus one here but Allen Creek drain does run under Argus 2 uh however it does the groundw does not intercept that drain it's probably the groundwater maximum depth or yeah the highest depth is about six feet from the drain so it doesn't mean the drain could not be a prenal path prefer sorry preferential pathway but it uh the the groundwater not an intercepted it

054means that ground mon was not likely to enter enter the drain at least at Argus one and Argus 2 uh next slide so uh the current status uh we at Eagle here uh received a groundwater investigation plan um which was submitted in January or I'm sorry it was approved in January um and then there was also a GSI professional pathway component to that uh as a separate plan which is approved in March and uh Vapor intrusion investigation ongoing so the vapor intrusion investigation's been ongoing since like 2019 so it's been it's been going on for quite a while and this is just some figures from the most recent uh some midles we received from GEOS uh I just wanted to point out to show where like sort of the groundwater sampling Wells are at uh

055these green ones are the proposed Wells uh they're going to be at varying depths uh you know one thing to point out with coronated solvents as they tend to dive because they're heavier than water uh so these will be uh nested Wells which have shallow and deep uh sampling areas um the red the red uh Wells are what have previously been installed so they've mainly just been on site uh so uh we're looking forward to seeing more data offsite and uh you know dilating the extent of this contamination next slide uh and then for the preferential Pathways this is kind of hard to see I think but uh they plan to do passive sampling uh in the manholes on on uh sort of along West Williams Street here and also upgradient on Fifth Street uh

056so they'll be do that's that's Vapor sampling so they'll be doing passive Vapor sampling uh in the uh sort of storm storm holes storm conveyances here then they also will do some uh soil temporary groundwater Wells and soil gas sampling along here in the right of way sort of near the uh storm storm sand lines in West William Street and that is it for Argus uh went pretty quick so I probably got some time for questions all right Commissioners questions Comm Curtis So for the new wells is there an expected time frame when the wells would go in and how long there yeah so um I don't have so they're they've they have permits pending with the city so they're in those City rights away I think that's kind of what's mostly been uh they've

057been waiting on recently uh and then they also added some additional like the preferential pathway investigation was not previously from the January report uh in their permitting that they were asking for so they had to amend that uh so I believe you know uh as far as I know it'll be sort of like this summer is kind of when the uh time frame is but uh I don't know for sure if they've gotten their permits yet missioner Brown yeah so yeah thanks uh Chris um is um I mean that deadline that that time is the expectation for monitoring weals but um it's not clear to me what the goal of the remediation project is what's the goal just to prevent Vapor improve in in people's basements or will this will there be some kind of

058groundwater treatment uh well I mean there is no sort of the you know the the program is that is a risk based so as long as they manage the risk they you know whatever the remedy is for that uh you know if it does manage the risk then it's acceptable so treatment could be one thing I know they've talked about Source removal on Argus one uh I guess some of the issue is uh Argus 2 and Argus one are both you know take up the whole parcel essentially uh except for some part you know where the at least where the majority of contamination is so it's difficult to access with the building on top um you know there are ways obvious or you know that's there are ways that could be done but yeah I

059sort of I guess at this point that hasn't been discussed very much um and that uh right now they're just sort of investigating to see if you know if there's receptors for the contamination and if there are risks to those receptors mitigating those risks so hopefully that answer the question um yeah okay I mean so with the vapor intrusion treatments I guess it's captured um the uh usually so if there's a vapor trusion issue the solutions usually a mitigation system installed in the home like a radon mitigation system that kind of system uh so it's not it's not treating the contamination it's just preventing the vapors from entering the home yeah yeah or it's just dispersing them outside yeah right okay and there are sort of like air quality things that are involved with that

060but oh so I just want to say I'm very familiar with this area it's very close to my home um and I would like to know um if there's ongoing monitoring of those homes that have the VAP for intrusion systems yeah they commission them for at least a year so they there is a commissioning process when they install mination system uh it is eventually handed over to the homeowner um but uh yeah so usually it's uh up to a year of uh sort of making sure the the proper uh vacuum isene in the mitigation system and then after that it's handed over to the home number so um those are terms that are not exactly familiar to me so um do you mean that um there's something that the resident can look at some kind

061of monitor that says this is an X level and things are good yeah so they uh what when there's not uh across the board always the same thing but geosc uh there is a visual uh sort of Mag or Magna helix or magnetometer so it tells you like if there's pressure in the system or in this case negative pressure in the system and then there's also an alarm uh so if the if the uh fan stops or the fan loses power for sets of great of time and like the geosync is alerted through like a remote sensing um but yeah the home owners the homeowner also given sort of a operation and maintenance uh sort of manual uh to go along with it uh once once it's handed over so it's really all about air

062flow not about what actually comes into the house so we don't know the chemical content or what yeah so the the idea the mitigation system is nothing enters from below the slab because it it creates a vacuum so uh yeah there should be no you know like the air underneath the the slab over the basement would not uh would be sort of vented out rather than being able to uh sort of exchange with the basement ER right so I'm just wondering I guess when I think of monitoring I want to make sure that the people in the house are are okay so is there there's nothing more than just the pressure monitoring that that we know of yeah uh yeah the you know the idea is if you have the negative pressure nothing like that

063nothing from the subsurface can enter the home so yeah as long we're not usually not measuring specifically there may be some indoor air uh measurements if there was previously indoor air um samples taken to show that the system's working like if you had previous prior to the installation um sampling done and then post installation sampling done you can kind of show that you know indoor concentrations have decreased but in general if the mitigation system is properly commissioned and installed uh it just prevents those Vapors from entering the homes so they're sort of like not more sampling as far as like the concentrations of contaminants and one last question for me anyway is um the um the responsible party are they going to continue to track and identify the um the plume as it moves because

064it seems like there's some unknowns yeah I mean they they have responsibilities under the statute to define the contamination so that's kind of part of it so they have to manage the risk and they have to you know well maybe first is divine the cination then manage the risk so uh yeah they haven't done that yet so and we've uh I guess that's been kind of a point uh between us that we've been uh sort of hammering on them so uh as I as I showed they have submitted some work plans now that they're um working towards that so once we have more information you know things can change but at this point we're just looking to see how far from Argus it goes and then we could kind of figure it out from there

065right and and do you provide reporting regularly to um our office of um Environmental Management uh I mean not directly I mean uh everything is pable but uh yeah I mean I know uh for some of this the work done in the right way the city has received some reports from GEOS synx since they got um you know that was part of their permitting process um but other than that I guess yeah I'm not sure okay thank you anyone else okay thank you Chris yep hi everybody I'm Dan I give it a me sorry I'm on it uh Dan wild uh another eqa project manager I manag the north half of Wasa County uh that's my area so I the project manager for arm and cleaners we're we're doing some work out there right now

066uh let see Arma cleaners is a former dry cleaner uh was active commercial dry cleaner located in downtown an arbor Primary Residential area in 1985 improper handling of dry cleaning waste was documented and a release of tetrachloro ethine pce or perk in soil and groundwater was first discovered uh pce is a non-flammable colorless liquid and a known carcinogen mainly used as a dry cleaning agent and metal degreasing solvent a lot of work has been completed since 1985 as you can well this is more recent on this map uh but included a limited soil excavation in the northwest corner of the property that was completed by the owner under Eagle supervision and many off-site investigations to develop a conceptual site model of the source area and migrating plume every house in the migrating pathway has been

067sampled for potential Vapor intrusion but only one home was identified needing a mitigation system and three of them are and the three of them are sampled quarterly to monitor for air quality and subsurface conditions so those are the three uh directly touching the arm and cleaner site boundary there next slide please we're completed December 2021 the building was abated uh then we demolish the building in January 2022 February 20 22 we did waste characterization sampling uh the slab of the building was left in place so we are looking to sample for future disposal and then we were delayed until 2023 due to some issues on site and with a RightWay permitting next slide please so our sampling plan to characterize for Waste we separated out our hazardous non-hazardous soil disposal we split the property into

068five separate areas collected samples from the 0 to 4 4 to 8 8 to 12 and 12 to 18t intervals like a big old layer cake uh you can't see it but everything highlighted in yellow is was determined to be hazardous for disposal so that's a big increase in cost but we were able to save money by separating those out uh Sarah nedrich was kind of the the leader of that push before she left us all right uh next slide please so we had to re-engineer our remedial actions uh so we decided to do insitu soil mixing so we the property was split into 25 cells with six to9 columns in each to mix the top five feet of the site was excavated and disposed of to account for swelling during the mixing an excavator

069with a 12-ft arm and rotating augers on the head of it was used to mix the soil down to about 20 feet below grade across the site and during during soil mixing sodium persulfate and Portland cement amendments were injected injected from the mixing head to oxidize contaminants and then solidify the soil to the appropriate compression and compaction requirements next slide please current status uh this was taken about a week ago uh they should have the straw thatched down now with this with the grass seat and but remedia activities were completed this month uh damage sidewalk we just got the go-ahead for the permit on that that should be poured this week and the site will be restored with top seed and soil top soil and seed mix that one up all right uh next slide

070please and so future work uh Pathways that remain are still potential are vapor intrusion groundwater surface water interface and drinking water protection so I think the biggest concern right now for us is the vapor intrusion pathway uh based on the most recent sample results future work will include verification sampling on the arm and cleaner's property to determine the effectiveness of our remedial mixing uh other sites with similar contaminant levels have seen a 90 to 94% reduction in contamination so I'm pretty excited to see our results we're currently working on that work plan now uh following that to address the low-level residual contamin contamination in soil and groundwater offsite uh we plan to develop and Implement two phases of offsite remedial injections um within the offsite plumes at 220 West Mosley and 628 South of Ashley

071uh that'll include uh monitoring on the site and off the site um and that should also prevent contamination from um back flowing back onto the Armic cleer property as well that's all I have any questions course it's Sarah the former project manager all right go ahead hi Dan thanks I guess I thought it might be kind of fun to share um so this is like a state funded project all the money for this where did it come from and how much have you spent doing the remediation that's more of a u question actually uh since you secured plenty of funding for this before you left um so a million dollar is from squi funding um I don't know what that acronym means off the top of my hand I apologize uh and I can Google

072it Sarah you know it off the top of your head anymore have you forgotten that all it's surface water quality protection fund thank you there go thank you I don't know the exact acronym but that's more or less it's for protection of surface water yeah I haven't thought about that in a while um so that's where a good chunk of the funding came from rest of it estate uh from our normal funding sources um I would say that's tough so we essentially had to fire our contractor that was previously hired they were not able to complete the work per our specifications so we parted ways with uh we had issues with dewatering due to the soil quality or a lot of silty silty soils they were not able to dewater enough for our engineering controls

073to prevent volatilization uh prior to dewatering and excavation um so we kind of went back and forth with them on that the problem was they weren't dewatering so therefore our engineering controls wouldn't work uh we had misters in place and it only works on desaturated soil so since there's still water in the soil we couldn't uh prevent volatilization um so their dewatering method was ineffective um we're also delayed due to the uh water I think the water M being redone on West Mosley so I think we're around the $ three and5 million range for State funding um and that doesn't include the approved 700,000 for the offsite injections that was approved last year as well I think that's more than I had budgeted for three years ago uh disposal two or three thanks thanks to

074co and corporations uh costs have gone up for not only disposal but uh everything else uh new Michigan funding as the other source Thank You Cher well um I have a question about um across the street on Ashley there appears to be some work being done is that related to this cleanup there's a a large apartment building and uh to the northeast of the site to the direct east across actually yep uh that's that's been done hasn't it that was built a couple years ago yeah the building is built but right now there's some activity oh yeah yes uh yeah they asked if they could use our area as kind of a lie down yard uh and we said no for liability reasons uh I can get you that information that's buried in my emails

075somewhere okay that's curious so it's unrelated to unrelated to us yeah thank you yep so um now that this property has been remediated who is the owner and what's the long-term plan for the property do you know so the owner no I don't know uh short answer the owner Remains the Same they're non-liable party they allowed us access uh to this site we had to kick out the the dry cleaning tenant prior to the work starting uh they will remain the owners and they will most likely sell it uh to a developer this area does remain in the historic district so they have to comply with the hor historic district uh rules and regulations so they would have to go to that board uh so I could see it only being you know single family

076residential houses that are built here uh they're not going to get a giant high-rise in this location unless the historic district approves that one right and what's the risk of um Vapor intrusion or whatever in the adjacent sites ones where you have the Stars so the property to the north already has a mitigation system that had been installed years ago um and then we're those three houses on this figure they're the ones undergoing quarterly monitoring for subslab and indoor air um following our injections I have two different contractors that are working on this they're going to work together uh following the injections to monitor the air quality and subslab air quality for all these properties um the houses Beyond this have already been screened out for Vapor intrusion uh the vapor pins remain in most

077of them so we could go back and Sample them if necessary um so I'm sure there's going to be a post-closure monitoring plan in place maybe monitor for a couple years if levels are the same uh we'll probably cease that or reduce the frequency of monitoring maybe maybe an annual event or something okay okay thank you anyone else problem okay also near my house in quite the area get out of an arbor right thank you very much for your presentation not problem thank you everyone all right if we're ready hi uh good evening everyone um my name is Ashley ler I am an environmental engineer project manager in the dist Jackson district office and I'm going to talk about the Broadway Park West site uh next slide yeah so uh you may know this uh

078if you don't know it is Broadway Park West you may know it as the manufactured gas plant uh long the hiran River on the north side of Ann Arbor uh former mishcon site it was originally built by Ann Arbor gas company later reincorporated as Wasau gas company uh and then uh it came to Michigan during consolidation in 1938 it continued to operate um until the late uh 1940s and was formally decommissioned in late 1950s um after that that uh mishon developed a service center on the property and uh from all of this former um coal gas manufacturing uh there's a number of contaminants characteristic of of those types of activities uh volatile compounds like Benzene toine ethylene and xylin that we call betex uh semivolatile organic compounds uh polynuclear aromatic hydrocarbons those are your like

079heavier petroleum compounds and you know tar oily materials then you've got a number of heavy metals and also cyanide um various uh environmental investigations uh by mishon began in the mid1 1980s and they've investigated remediated and stabilized various uh areas of the site over the years um there were some underground storage tanks and structures they removed obviously stained surface soils um they ran some pilot studies uh and so on but for today's presentation I'm going to focus on the most recent remedial actions so roughly what's happened over the previous decade uh as well as the current plans for redevelopment there's a number of different parties involved um DTE Energy is the successor to mishan and the party responsible for the environmental remediation overall and I have their most uh recent groundwater monitoring results um over

080the last 10 years to share the current owner is lower toown Partners LLC they're a single purpose entity to hold the real estate Roxbury group will be the developer of this property and I've been in close communication through uh the process with their uh consultant smme they have also formed a nonprofit called the lowertown riverfront conservancy and uh that was formed to manage the proposed public use areas of the site um the developers activities specifically the developer is of course a non non-liable owner completed a baseline environmental assessment on the property when they took ownership uh so they've been able to receive some Brownfield funding uh through Eagle uh and I can provide an update on their site preparation activities so the site uh which you see here um I'm sorry the text is so

081small but I'll I'll try to walk you through it um it's 11 um 11.38 Acre Site and the Western portion that you kind of see in green there um was historically uh undeveloped although it had uh stock piles in storage the Eastern portion where you see those circles you know those were like the gas holders that were part of the MGP operation um you see in the gray there's a big foundation that's where the service center was so the Eastern side of the property was much more heavily developed um by by mishan uh to the north of the site you have the hiron river uh main Channel and then just uh just above that just north of that the uh Argo Cascades uh and its outlin into the hon River uh just off of the

082map on the very Northwest uh upper leftand corner uh that's where uh Argo dam is and this property know way back a century ago uh was was filled there was a former River channel that was filled in through the central portion of the property uh but even though the area is in a flood plane uh water levels here are are well controlled by Argo dam being immediately Upstream uh so getting a little bit into the development plans for this site uh in 2018 Eagle uh received and approved a response activity plan uh from Lower Town Partners the current owner of the site um you know through their developer and consultant and their plan involves dividing the property into three areas that will each be addressed um according to its use so you have the um

083Western portion of the site um extending over into the riverfront toward the East and that will be the public use area um focused on you know recreational use open to the public uh then there will be on the Eastern portion of the site uh commercial building I believe they're planning a small hotel uh and on the uh Southern portion of the site uh Residential Properties so town homes or Condominiums and there are appropriate uh site specific criteria selected for each um the specific environmental response activities uh will report the proposed uses of the property so on the public use areas because those will be green space uh they have done a lot of excavation of contaminated soils um in areas where they have not uh done excavation there will be exposure barriers either uh composed

084of clean soil or uh parking areas Pavements building foundations um to prevent direct contact then for the buildings um because the petroleum volatile compounds there will be Vapor mitigation systems designed for the buildings at the time of construction and then there will be restrictive covenants placed on the property to restrict the use of Wells uh for extracting groundwater and that will preserve the elements of the development that are protective of Public Health in the environment next slide so um back in 20 9 uh DTE Energy uh conducted some remedial investigations uh that identified uh oily materials and tar materials in the shallow subsurface soil along the shoreline of the hiron river as well as in the central portion of the property near the former uh gas holders and tank structures um in response to you

085know this information uh they submitted a response activity plan Eagle in 2012 and conducted um we approved that and they went forward with the work which consisted of uh dredging nearly 50,000 tons of sediment and Shor loin Shoreline soil uh and then they installed uh what you see here this uh schematic shows their uh napple trapping cap system uh on almost a thousand feet of the hon River Frontage what this does um napple is non aquous phase liquid uh it's pretty much I'm calling it oily material just for uh just to get away from the jargon um but essentially that's that's what it is it's um oils that are either that are you know their own phase within the groundwater so sometimes you know floating on top potentially or if they're denser than water um

086sinking as a as a body of contamination um so this cap uh installed on the shoreline uh helps these materials from reaching the hon River uh groundwater at the site is relatively shallow um as you might expect being next to the uh next to the hon River it's between two and 2 and 10 ft uh below ground surface in uh sandy soil flowing toward the Northeast uh but there's a hard silty clay layer below 10 ft so the napple that we're seeing is is isolated behind the cap both both by the cap itself and the geological materials beneath it um the the trapping cap was constructed with sumps uh which allow um DTE to monitor this the function of the cap and note whether there's any you know oils accumulating behind the cab next slide

087so this is a schematic of the site in 2013 post construction again I apologize it's so small um but you can kind of see the gray um gray stone line along the hon River that is the cap itself um and in 2014 uh based on the completion of this cap uh mdq granted no further action status for this Nearshore area of the property um and the sediment between Argo Dam and Broadway Street Bridge next slide they have continued to uh monitor though uh over the last 10 years when we talk about managing environmental risks we think of them in terms of exposure Pathways as you've heard from Chris and Dan so where there's a potential for contaminated groundwater to vent into surface water we are using water quality criteria that cover all uses so protective

088of Aquatic Life Fisheries drinking water sources and people who may be using the water bodies recreationally as we know uh next to the next to the Cascades with all kayaks um our criteria cover all of those uh potential uses um we specifically uh approved um site specific mixing Zone criteria for the site back in 2010 and those were updated um based on the proposed use of the property in um 2019 I believe also to uh to cover acute um acute risks to uh Aquatic Life after they installed the napple trapping cap uh DTE committed to a 10-year monitoring period for the GSI pathway and we just received their final round of monitoring uh like last week um they have continued to be below criteria um there is still contamination present on the interior portions of

089the property um but those sumps I said where they could monitor if um if those oily materials were actually reaching the cap uh DTE hasn't seen napple in any of those sumps over the full 10 years of monitoring uh nor have there been any exceedances of criteria at the compliance Wells placed between the interior portions of the property and the river uh that 10-year monitoring period uh is actually based on a conservative estimate of groundwater flow rate um so it takes 8 to 10 years at most for groundwater on the Eastern portion of the property where that contamination is uh to reach the hon River if it were going to um so at this time you know I just got this data but based on a preliminary look at it um it seems that they

090will will not need to continue monitoring and at that time those Wells and sumps will be removed next slide so uh moving on to the uh to the current of the property Redevelopment um I got to rewind to 2017 um as they were preparing for redevelopment uh they conducted a shallow soil data Gap investigation on the western portion of the property I believe this was done by lower toown Partners Roxbury group um but it was focused on the uh what will be the public use areas of the property uh historically part of the coal gasification process involved removing corrosive compounds by passing the gas over trays of iron oxide and that was to capture contaminants um sulfur and cyanide that that would make the gas unusable but then those waste materials were deposited um on

091the undeveloped portions of the site primarily the Western um Western portion um these soils are actually like visually characteristic they're they're bright blue like Prussian Blue like the paint pigment um they're not particularly Mobile in the environment so they're less of a groundwater issue uh but they are a direct contact Hazard and needed to be removed prior to the Redevelopment so the 2018 response activity plan proposed by the developer consisted of uh proposed Excavating all of the blue soils to a depth to the maximum depth um where they'd found them of 8.5 ft and then everywhere else in the uh where they had previously identified um petroleum compounds heavy metals and coal tars those areas were excavated uh the upper two feet um as a you know reasonable distance where somebody might encounter them uh

092who's using the property ultimately the goal is to have 2 feet of clean soil cover in o over the entire public use area uh whether that was existing uncontaminated soil or soil that was imported as clean backfill everywhere else um buildings and parking lots would be used as as the cover um so this excavation work was completed uh this past fall and winter and we just received the results of verification sampling uh which is kind what you're looking at is is the map of the public use areas and where the sampling was completed all of the verification samples were collected within the top two feet uh which would be that Clean Cover um exposure barrier Zone using a method known as incremental sampling so you've got the site divided into 18 units and grided out

093and from each of those units um 30 increments of soil were collected and composited so that significantly improves the quality of data that you get versus a single discret sample um then you then they also took a triplicate sample which they could use to compare um to compare statistically to ensure that the data was actually representative of the material which is always a challenge when you're uh when you're trying to um assess materials for direct contact the decision units outlined in lime green are the areas that were excavated and backfilled and in those areas the verification sampling was mainly to confirm that the soil brought onto the site was not contaminated so you see a slightly lower uh sampling density there like in six in the central portion of the um of the West half

094of the site the based on past investigation soils in the remaining decision units those are the ones outlined in magenta uh were already believed to be below criteria based on previous data uh either because there was no contamination present or because they were part of previously remediated areas and in those cases the verification sampling was conducted to confirm um to confirm that with better data quality all right next slide um I just want to go over what's next um we're still uh looking over this data it's very recently the last couple of weeks and uh the the next step for the site is for um I believe Lower Town Partners intends to submit an NFA for the property they're going to have to get some data from DTE to complete that process um but in

095order to qualify for an NFA they have to have all of the different exposure Pathways covered so they would need to have the restrictive covenant in place and they would need to have the vapor mitigation in place and obviously these buildings have not been built yet um so that's coming down the road and we're currently uh in discussions with them about the the best way to way to achieve that uh that's all I have at this time happy to answer any questions you may have right Commissioners you had a lot of information provided to us today commissioner dish council member dish it's mine either way um thank you for all of that information information um this project is an eagerly awaited project in my ward um and people are wondering why it is taking so

096long for them to get started and so it's you've told me a story about indeed they have started and there has been a lot of Labor and they have finally cleaned the house and now they'll be able to build so that's that that sounds really really great I mean pending you know your review of these latest St samples but I think everyone can really feel good that this has been an extensive cleanup I don't know Rita if you want to raise the issues around um uh um erosion that yeah yeah thanks um once when dis and I were at a meeting just last night and a neighbor of this area um said that he observed in the recent rainstorms some flooding in the westmost area that that the water kind of came into its natural

097path um in that floodway area I saw some ducks um and I my concern when in thinking about that was what happens to that surface layer that's been placed there um is it going to erode is it going to result in some contamination of the hon River um and will there be some um placement of grass or other green ways to prevent erosion of all this work yes yes um absolutely that would that is something that uh was proposed in the 2018 response activity plan obviously they're you know in the middle of site work so um ultimately yes a vegetated cover will be needed to stabilize the soil um as far as you know contamination of the river we're we're mostly focused on um those those surface soils being a direct contact Hazard and not

098necessar a concern um to to the river itself not a concern to to groundwater so um right now the site is fenced people shouldn't you know shouldn't be accessing that site so they have a little bit of time to to get that in place as part of the development okay but do you expect it sometime perhaps this season this growing season it's all there right now that's a good question I don't have that that information for the developer right now okay than anyone else Brown yeah yeah thanks um thanks Ashley I have a few questions um out of all the contaminants that have been um detected so far on this site um which ones are expected to migrate the fastest or easiest in groundwater wouldn't that be like Cyanide and the metals uh that would

099be the purpose uh primarily the napple trapping cap um dissolved uh dissolved petroleum related compounds um the cyanide actually is not a particularly mobile form that's also why it's still here after decades and decades oh okay and um and so what's the estimated lifetime of that nap cap and why are they why are they going to remove the wells and the sumps because wouldn't that remove um opportunity for you know testing in the future because as we all we've all heard about landfills uh caps and about there's no landfill that's been successfully capped for more than a decade in my know to my knowledge so I'm just wondering what what precautions there are in terms of um figuring out when uh when that cap has been breached through natural processes or flooding or something else

100and how would that be tested if it were if there were a breach so what what we're seeing based on the data is they haven't actually seen an apple move from the interior of the property to the um to the sumps it has not reached the cap itself so while the cap is capable of trapping those materials the the materials are are less mobile than um than I think was originally feared granted I I've been um my experience with the site is relatively recent um I just got involved with it about a year ago so a lot of the decisions associated with the um with an apple trapping cap I'm I'm still learning about myself yeah I'm just a little concerned that they've decided that 10 years is long enough to decide that it's it's

101done for Infinity you know so I hope that there's some kind of a plan and they're leaving means in place uh such as sumps and Wells I'm not sure what the rationale is for removing the sumps and the wells and um because it does kind of reduce the opportunity of detecting whatever contamination that might show up and I don't see any reason why it can't be tested um over various periods of time in the future just to make sure that you know the theoretical um the theoretical success of the tree of the containment has actually been achieved or not but certainly something I'll be keeping in mind my understanding is that it was um has been approved by eagle was approved by eagle in the past and that was based on um Based on transmissivity

102data um based on the the groundwater flow rate so in a sense that 10year per period has been the test that's that's my current understanding okay thank you Steve good question I guess my question associated with that it seems like it's a no cost issue to retain those sums and and so why not um yeah uh anyone else all right well um I want to thank um Andrea and your staff everyone for joining us and providing this information it's in our backyards nearby everyone and um your efforts to track and keep us safe are very much appreciated you're welcome Rita thank you so much for heing us here thank you for hear the opportunity for the project man here to present some of the work they have several projects some of them are state funded

103so we're constantly working trying to protect based on our regulations um like you say will be maybe nice if anybody has any questions said with Alma Chris is here like Chris information is available or I can provide that information to you um or any project manager for additional information happy yeah thank you all right um all right I want to thank everybody for hanging in this has been a another packed uh agenda um and I will move us along to our next item which is um it has to do with the green streets um program that we discussed last month with Jen Lawson and Jerry Hancock and um the the issue has to do with now we were presented with um a resolution to consider um advancing forward with our support um and I guess

104I would like to know um if anyone has any questions or comments about it or if we'd like to put it up for review um and figure out our next steps on this um yeah for you right thanks Aaron thanks bringing that up um is it okay if I just unmute and say some of my my thoughts yeah please do okay um well admittedly I was not at the meeting to hear the presentation although I I did watch it um as well as the discussion for the recording and um I feel like even with the the Q Q Anda you know the questions and things that were answered written later that I still have a lot of questions um before I would personally feel like I wanted to vote in favor of it um it

105was it was on the environmental commission at least when this conversation started what 10 12 years ago a little bit longer than that um and I I from what I what I understand about the proposed changes there are some things that seems like it makes a lot of sense um like I I understand why we'd want to maybe change the title um from Green streets to to just something that's more specifically about storm water because it's not necessarily green although I have other questions around that too um you know I I appreciate the um that this would go not just from Curb to curb uh but essentially widen through the right of way and be essentially sidewalk to sidewalk and so there there are a lot of things of about this that I think you

106know factoring in underground utility projects and stuff like that um requiring the maintenance plans to be reviewed I think all of those things make a lot of sense but there are some things that I have questions around and some things that give me a little bit of pause um and one of them is um if we I understand it's not always possible to have the the green portion but um you know if we're looking at the other potential benefits of the vegetation portion of what was the intent of the green streets projects I mean these are things that are addressing heat island effect and other things so I think if one of my questions is if if that is not explicitly being encouraged by this to the same degree than it was before I'm wondering

107if that's also going to be um addressed in other infrastructure projects you know is is that part of um you know Landscaping ordinances or or something else is there is there other stuff in place that's going to make sure there's as much vegetation as possible for the other benefits so that's one thing um something around the um you know the addition of bike Lanes being a challenge to implementing the green streets policy as it's written so I just have you know questions around that like the bike Lanes I can think of the the additions are not widening the streets so I I was a little lost in why that is um a challenge to implementing the policy um you know and and some things just about in general changing even if you have to tweak

108something changing something from a policy to a guideline I think it it weakens it and I and I'm not sure how I feel about that you know if I if there are some changes that need to be put into place so that things can be implemented um then I then I understand that but the switch from policy to guideline makes makes me pause a little bit those are some initial thoughts I have others but I don't want to totally dominate I want to open up for other people's thoughts on this yeah thanks Anna um well I'm really glad to see Jerry Hancock here oh my gosh you're still here that's great um are do you feel um that you can jump in and address some of these questions because I also have another idea of

109how we could approach tonight but let's go yeah just just a couple thing so um the idea of changing from policy to guideline it's it's not changing it's it's called a a policy statement and the previous version was a guideline and it's still a guideline um and then as far as taking out the green um the green streets we were doing that because of the expectation of the public with the green named the green streets policy and we weren't able to um put in as much green as we had hoped over the last 10 years so this is just kind of acknowledging the reality of doing infiltration in the right of way that more often than that it's probably going to be underground but certainly where there's um where there's space we prefer to do

110green um and sometimes it uh would coincide with some of the um uh like pedestrian and bicycle changes where you're making um intersections more pedestrian friendly introducing Islands um that could be the green storm water component so the changes aren't uh encouraging or discouraging any any of the green it's just kind of to set the expectation that um more often than that it's probably not going to be green because of the space constraints and that and that just kind of reflects the last 10 years of us implementing it Mr Brown I'm sorry Chris had his hand up first oh I'm sorry I missed that I'm sorry Chris please Pro see Stephen you can go first anytime Jerry I presume the ultimate repository of these guidelines and standards will be the orange book correct which um

111is no longer called the Orange book but you are correct thank you I'm glad to see him in there very good yeah they're they're ref now that is a live document instead of a paper document and so if this change goes into effect we it will be inserted into um the live document on the web very good thank you yeah so so let's see okay are you done Chris yeah um I'll um I was just you know I am a bit confused just as Anna is I didn't I wasn't attending the last meeting but I did look at the presentations and it's certainly a complicated topic but one thing that immediately comes to my mind is that there's two aspects to storm water there's the runoff the flooding Hazard and then there's the uh contamination

112of the river you know that comes from and we the city is under a consent judgment you know to reduce its phosphorus pollution and um I'm not sure what the exact numbers here for Ann Arbor but traditionally maybe about half of the phosphorus pollution comes from storm water runoff and other communities in the in in the Great Lakes region so I was wondering the Green Street policies don't seem to address this aspect of it they're mostly trying to address the uh storm water management uh in terms of flooding is that correct Jerry it's it's the opposite it but infiltration um par all right so the standard if you notice there's three different standards and but the minimum standard is the first flush well 90% of all pollutants and runoff occur in the first flush so

113that is our minimum standard so um in it primarily is a W uh is a water quality issue infiltrating though the more we can infiltrate then then you do start to get into controlling volume um so first and foremost it is a water quality treatment and but we this policy exceeds the infiltration standards in the washing count the rules of the Washington County Water Resource commissioner so we're basically trying to um infiltrate even more than what the the normal standard is um and base it on the site conditions basically like if the site conditions allow we're going we're going to exceed the county standards that's that's that's sort of the the Baseline of what this policy does sure um but you know what I've seen most of the major projects I've seen to control the

114flood involve large underground reservoirs like you know near Pioneer High School and like at the University campus uh near where the irion sculpture is some and so in that in that sense you're just you're storing a lot of that first flush in those tanks so I was wondering how how that um how those T what's the plan for um you know for maintaining those tanks to you know to control the the contaminants that might be in the sediment that's accumulating in them so for example the the tanks that are under the under Pioneer they there is such a large Watershed draining to that point that that even though that's a large facility it is only treating the first flush from it's it's like 200 some Acres of developed neighborhoods it's very it's very large area

115so um we worked on that project with the county but the city has maintenance responsibility and that particular one and so our uh Public Works staff uh have uh periodically gone into it um they're very deep and they have to go in there people have to go in there to to clean it out and they and so it has been cleaned out so we we use City Works to put it on a maintenance schedule um I don't know the specific number of years how often we're going in but um it is on our maintenance schedule and city um crews are doing that okay do you know where that settlement goes it's well it's removed from there and out at the out at Wheeler we have um containment areas they take it to and then they

116dispose of it after that oh yeah I'm just wondering where it goes I'll ultimately um I'm not sure what I assume that it's landfilled yeah most like yeah but it's first decanted at the at Wheeler okay uh commissioner Dale yeah um first I I appreciate you coming and I I trust that you know all the answers all the questions I might have and I still have an awful lot um and so you know and some of them I think might involve probably more conversations we might have time for this today so um you know some of them around some of the um you know how the city and the county and the DDA and how everybody works on these projects and um and how involved the city is with the designers and the maintenance plans

117and you know sort of how this all RS into the cost of Maintenance and um and I think some of you know some of the concerns that sounds like it may have made it difficult to implement in all the cases that otherwise people would have wanted to and so I I I think I I feel like I have a lot of questions that are sort of big questions and it this I think this is a really important issue um and so I'm wondering you know I know that people want to move this along but I'm also wondering if there might be an opportunity for us to push back voting on this here until the main meeting so that maybe there could be some conversation like a a you know a work group where we could

118have some conversation with Commissioners who are interested in learning more and having sort of you know talk to with you more and and maybe some other so that we can fully understand the proposed changes from from the original to now because I I'm also I probably could use refreshing and looking at the last policy or guidelines better as well MH I mean it's fine with me um but your your opening statements you did pick up on the most significant changes I would say that um so you already have a pretty good a pretty good um handle on what we what areas we changed I think you mentioned like three three things and they were the top the three biggest changes so um I have to say that this is one of the situations where um

119I appreciate that um the city staff have brought something to our commission for discussion and um it would be great and in my opinion for us to take the time to consider a little deliberately unless there is some Rush some reason reason for moving forward quickly if we could have um one more month to have the kind of discussion that Ana described is is that anything that you can comment on Jerry in terms of timing um I can um the timing is that I am going to retire from the city and on July 10th I won't be a city employee anymore all right okay I'm not happy about that but Jen Lawson was hoping that I could get this as far as long as possible before retiring that's that's the timing right okay um but

120there's not any City administrative issue and I don't hear from Anya that there would necessarily be something that would be a huge change but I think it would be a level of confidence um for a vote and um I would like to propose that we do that that we identify some um members of the commission who would be interested in um joining with I assume commissioner Dale would like to do this um and if there are others who would like to join in and um have an opportunity to talk with staff about this particular change in the goals I feel like given the discussion or the inclusion of the reference to vegetation that that's one of those things that um kind of clicks with me with respect to our our natural features and incorporating that

121as all of this process um so I'd like to make sure that that even if the title green streets doesn't remain that there is a green component that we can rely on council member dish thanks uh thanks chair Mitchell um yeah I just want to ask a clarifying question um if I understood you correctly Mr Hancock your statement was that it is due to space constraints and not budgetary constraints that it is not always is possible to um to have a vegetation component for infiltration primarily yeah I mean just if you think about a road RightWay it's not just what's on the surface it's what's below the surface you know if you you have water sanitary storm sometimes multiple other private utilities um and that's that's really the driver behind um how much um storm

122water control we can do is usually it's more well the the the site conditions that are laid out in the policy about slope flood plane and soils those are first but then then after that it's how much space do you have in the RightWay to put controls in yep that's really helpful I I appreciate you're saying that um now I granted I read it quickly so I'm not sure if I caught everything that's in there but what you said when you were talking to us about about this is that where there is space there vegetation would be the preferred method of infiltration is that spelled out in the new guidelines it's not but there is a reference to um a a manual in there and most of the examples in the manual are green okay

123sorry I'm just trying to take understand this because if it I don't know if it's coming to council but I don't want to be I want to be able to be clear about it so yeah it sounds like a great idea a to have um another session with Mr Hancock if he is willing to do this if he has the time um so that we can air everyone's questions and I don't know if there would be any ability to make language changes but oh yeah in view of the fact that the title is changing in a way that makes that that um invites a concern about the city backing away from a commitment to Green um it might be great to add a sentence that that kind of emphasizes that that remains the preferred method

124but that you know as with everything else you know we're going to go drill some holes too for geothermal and we're going to find that there's a lot going on under our roads and so you know we can't always have it so I wonder if in the language of the guidelines um themselves there there could be just a little bit more reassurance for people so that's that's all um you know that's all I wanted to say and I would love to be included in this meeting if it can be scheduled at a time where I can be free sure um just one clarification the T the title didn't have green streets in it before but the body body of it did mention Green Street so um and we and we have kind of scrubbed that

125out of of there a little bit in this [Music] version right thank you I think um I would like to proceed with that um approach to set a meeting within the next um let's say three weeks so that there's some preparation time actually two weeks would be better if possible um so we can prepare whatever material for this for our May meeting um um and so um I see that um uh council member dish and commissioner Dale are interested who else may be interested in joining this group Mr Brown Brown Curtis anyone else okay I'll consider myself a maybe and put myself in the list but I may not okay um thank you um so let's consider this um is it all right do we I don't think we need to vote on anything let's

126consider it sort of tabled temporarily or however whatever term might be yeah actually I considered this the first reading because um the actual um policy wasn't included the first time so that works out well because gonna have the second reading in May anyway so that's great yeah thanks Erin do you think you a went to meet or something Erin would that be possible or or what's that oh yes yep yeah scheduling like a when to meet or yeah I I find those the easiest actually but other people have their own preferences for those things yeah that would be really helpful yep I can do that great thank you all thank you Jerry thanks for coming this two in a row um Aaron would you be coordinating that meeting or um is that something you would

127like me and Jennifer Lawson to do yes I one of at least one of you would be helpful I think to help answer those questions but we can touch Pace after okay okay yeah thank you Jerry that was a surprise um me promoting Jerry to panelist so um I don't think you expecting to answer question I really appreciate that you were here because I think it really helped us get to this point so um thanks Jerry and I I anticipate that we'll be able to move forward next month but great better to be confident I think yes okay great um so with that I'd like to bring up and um you all it's 909 I know that we're past our usual meeting and time but I would like to consider the last final item um

128the feasibility study res resolution that was in your packet um and um I know that there was some in some information that came late um which included some notes from the office of sustain ability and Innovations um commenting on the original version of it and so I kind of put together um a version that kind of in that included sort of a Redline version um that shows the changes um and is that something Erin we could look at right now yes um I'm gonna um can you remind me I I'll just yeah if you want to tell me which um okay document here I can pull it go ahead and pull it up thank you um if we could do the let's do the one that's called the redline version two so people can see

129yeah okay oops I see it that one doesn't look like it no um that looks like the npl thing isn't it yeah that's not it oh it is sorry but I can't see the resolution oh my goodness okay so we need this is my email to you okay so if we can click I don't know what we'll open right now um let's do the PDF of Redline version to up in the upper right corner yeah this one okay yep that work I don't see it yet oh it's not sharing I know no I see the email oh oh I wonder if I shared the document sorry it's okay there we go Mr dish yeah while we're getting technically oriented I just wanted to respond there had been a comment from the public about um a

130concern it sounded like about the funding source for the $1 million for the phase two study there that funding source is Rock Solid and there is a million dollars in the budget for the phase two study just wanted to great news that's great news yeah so really what we're doing is is supporting the what the council has done or what's proposed in the budget right um and so this says red line but it's really green line um I um inserted some corrections that were identified um and so you can see the actual cross outs and the insertions um and I would say that everything um that we see here we see that um we're looking at a feasibility study um we've got climate change going on just a simple kind of a typo about a20

131um I accepted the comment about achieving a just transition for CommunityWide um carbon neutrality um it just acknowledges that our current electricity is from Dirty power um we have power outages next one down then the short um whereas Claus um accepted the note that says um that under some scenarios both Municipal and sustainability utility um electric utility are feasible um and then the biggest change um crossed out most of the um last big whereas CL so whereas a phase 2 study of municipalization would provide a comprehensive and authoritative estimate of the likely total cost to the city and would support the Public's informed decision making there let's go forward with the feasibility study so the language that I um included in that is not exactly as um was recommended by staff but I think it

132it is allows us some flexibility and still supports the the concept so I offer those um changes and ask for any comments commissioner dish yes so I have a comment on the um the the final whereas Clause now my understanding is that the phase two study will not provide an estimate of the total cost to the city of municipalization because the goal of a phase 2 study is to better assess and value dte's assets but it would not provide an estimate of what and therefore it's very important because clearly we want to go into court DTE is going to say our assets are you know worth 100 pounds of gold and we want to be able to say no they're not they're worth 50 cents you know so obviously I'm exaggerating but but but the

133phase two study will not tell us what it takes us um what it would take us to what investments need to be made in order to make the dte's equipment reliable so I either taking out total or just making it clearer um I mean well I think total just doesn't work there because it it connotes that we're talking about the or it can it invites the under the um interpretation that so I don't we just take out the word total let's do how about that uh uh well um I would say possibly authoritative as estimate of the value of dte's assets um and of course I'm not entirely confident of that language but but um yeah yeah because this I mean the phase two study is a valuation study is it not that's my understanding

134of it but but I think so what what here's my intent um and and maybe we can clarify with this um the intent is to um support whatever the scope will be of the yet to be written RFP that's all um and not to overly constrain that um at this point but the no matter how it's written the phase two study is not going to include the cost of making dte's equipment reliable yeah but we're not talking about reliability in this statement at least that word doesn't appear but when you say total cost okay but if we take out total we'll just say the cost or the value the value it's value right value and cost are not the same so R can I interject because Dr stz answerers some of those questions in the

135Q&A the the first one the the phase two is only going to be the value of the dte's assets the polls the things like that there's also going to be a cost that the phase two study won't address which is how much do we have to pay to to basically buy out DTE to not have allow DTE to sell Power in within an arbor that's a cost that gets decided by the judge right and then but but that's still you know when you say phase two cost they're going to have to do that's going to be the total of we're going to have to pay so I think you know what what the OSI wrote is probably more accurate and more you know the reliability comes even later after that that's another one further down

136the road let's look at the um last statement on this that shows on the screen with what Erin shows phase two study provide appraisal of the system's value which would be necessary to provide the public so it can make an informed decision about next steps condemnation proceedings right I think that um you could just put that statement in there right all right is that so would we like to vote on that as a group because I think I don't feel totally confident of that but go ahead we we could put that to a vote to include or not include that as an amendment you mean to substitute yeah yeah yeah would so I'll just ask the group is that a motion yeah I'm G to move that we um include the statement as indicated by

137Dr stals so it's stated in a positive in place of the in place of the green out y uh I second it okay uh all in favor of that change five two three five is that 100% except for me I'm going to vote on no okay all right um the eyes have it um yeah I I was trying to avoid including the condemnation word but that's okay um okay so here we go and then um if that is the amended version of our resolution um can we proceed to vote on the resolution I have one other question Rita yeah um I think it's the fourth paragraph it talks about uh less than 133% um of clean Renewable Power when I was looking at the executive summary I thought it was 19% % as on page

138three of the executive summary I think that might have been updated you know so I probably took this from an earlier document so we could put 19 in okay with that yeah okay so that's here yes okay okay and then the 87 would change to 80 81 also right okay there have does someone want to read me the language I can put it in or I will okay okay here it is um whereas a phase two study M done for number four okay here it is sorry um whereas a phase two study of [Music] municipalization would provide an appraisal of the system's value comma which would be necessary to provide the public so they can make an informed decision about next steps regarding a condemnation proceeding and Total Takeover of dte's assets is this like

139apostrophe yeah I think so okay yeah because I don't think systems value I I I think it does mean possessive yeah and there is a typo in the next sentence as well uh in the next resolve Clause sorry sorry if you scroll I can't see um probably it should be either advises that the Anarbor city council pursue a phase study phase two study or yeah or advises the annarbor city council to pursue a phase two study whichever you want but but without either one of those it doesn't make sense okay right that looks good to me and maybe just do the paragraph on the resolved at the very last it's really the last sentence there it'll all go on one page once all the changes are accepted okay accept all changes I me to unbold

140these acceptable to everyone looks like there's some Bolding I put in up above I was trying to make it so people could see right um and with that I would appreciate a motion to approve the resolution moved council member dish second council member C commissioner cith thank you and um all in favor raise your hand I'm done looking like uh all but one anyone opposed D all right believe this past so thank you all thanks for your patience now we've got another couple of pieces of the meeting to do and that is um I would like to ask your um preference as a group do we want to go through the um reports by the um it's getting late so I asked you you whether you wish to do our reports out report outs as

141we usually do or move further no one cares no you're saying no everybody saying no okay I'm actually okay with doing that um we need to okay I will ask you all to um let me know items for the next agenda certainly one will be a report back on the um storm water management um for that group that will be meeting our next scheduled meeting is um Thursday May 23rd 7 o'clock Zoom um and just a note for you all this is the um I see a c commissioner Curtis um this is the uh time of our um appointments for election of officers so I have served um and I certainly welcome anyone approaching um and stepping up to uh chair the meeting or run for vice chair your your choices um commiss Curtis yeah

142the energy commission voted on the seu to support that should we have the similar thing from the environmental commission [Music] um um and I so I think that needs to be a little bit investigated because I um I know that this particular one that um I was interested in presenting this to the group because of the budget coming up and wanted to make sure that we had our support and advice to council um and so I don't know if that's the status with the seu but we can find out yeah the seu was to support the vote of the people in language right right well not really the ballot language but just to put it on the ballot right okay okay um let's look into that and um anything else so that would be a

143future agenda item thank you um okay we have a second public comments session this is an opportunity for persons to speak up to three minutes please call 888 78899 and enter meeting ID 962 6453 City staff will select callers that have raised their hand by calling out the last three digits of your phone number um in order to electronically raise your hand please press star n on your phone you'll hear an automated announcement that the host is allowing you to speak press star six to unmute your phone and when speaking please move to a quiet area and mute any television or background sounds so that we may hear you clearly please state your name and address at the beginning of your comments thanks aarin um and do you see anyone who's raised their hand no

144no one all right I will entertain a motion to adjourn commissioner Curtis second commissioner dish thank you all we are adjourned good night thank you thank you bye
