BOARD OF WATER COMMISSIONERS AGENDA Thursday,January 12, 2006 7.30 pm at 339 King Street, Cohasset 7:30 Rules & Regulations • Update/Reviews 8:15 Maxwell Conservation Trust 0 West End Land 9:00 American Water • Operations Other BOARD OF WATER COMMISSIONERS AGENDA Tuesday,January 24, 2006 7.30 pm at 339 King Street, Cohasset 7:30 Old Business • Sohier Street Wells • Maxwell Conservation Trust • Cedarmere 8:00 American Water 9:00 Town Meeting Articles 9:30 Routine Matters • Abatements • Correspondence Other BOARD OF WATER COMMISSIONERS MARCH 21, 2006 339 KING STREET, 7:30 PM Chairman, Glenn Pratt Vice Chairman—John McNabb Clerk—Nathaniel Palmer Recording Secretary: Brenda Douglas Guests Include: Tom Keeffe, Tutela Engineering, Steve Siegfried, Eileen Commane, Steve May, & Jared Hill of American Water Services Meeting commenced at 7:35 pm. Gary Lipsett & Ken cook of Pond Street attended to speak with the Commission. The first topic to be discussed was the schedule of when the construction would be done. Glenn Pratt stated that DPW won't allow us to do a permanent paving until it has settled for 6 months. The area in which Mr. Lipsett and Cook live needs to be regarded before .the paving can even be done. The other issue is that starting on Monday blasting will begin for the T to move Pond Street. Do we wait until all work is done before regrading? This is an issue that we are looking at. Commissioner Pratt asked what we can do to maybe make this a little more bearable until the completion. The commission agreed to do some cleanup, and do some more temporary pavement. Mr. Lipsett is more concerned about safety due to the fact that there are large dips in the road. Commissioner Pratt also stated that as of Monday the trucks would be leaving the end of Pond due to the T work. Mr. Cooks concern is that when the construction is complete will the area from the street to his stone wall be fixed. The commission assured him that it would be loomed and seeded. It would be up to them to make sure that it is watered. SCADA/PLANT UPGRADES To date a new PLC installed upstairs a lot of equipment in chemical feed area automating places in the plant that never were. Fisher Porter console which is wired to older PLC does not function properly. The scada contractor tried to track down wiring to influent control after 8 hours 2 men were unable to locate and track 1 wire. In order to use the older PLC the man hours would be too numerous. Jared Hill has come up with two options: Either do what Steve describes unable to come up with hours and $$. The other option is to run new wiring from the old PLC to the new existing with a station in the pump room. This would be one wire running upstairs and well and downstairs. Glenn would like to have a tally to date what has been spent by each person involved in the upgrade of the plant. Glenn also want estimates on what is left that will need to be upgraded in the future, not just for scada, but chlorine, lime, etc. Commissioner McNabb asked that a new jockey pump be looked at since we have only one. Steve May stated that something has been order or revamped so we could use the old as a backup. 24 HOUR OPERATIONS Eileen Commane stated that it has come up for several reasons: cost effective to help pay for scada. The full time operators have been stretched to the max. The 24 hour operation was the reason to reduce the DVP. There is no question that the age of the water is a factor as well as tank turnover. The recommendation of AWS is to scale down we suggest that if we run fewer hours and check to see with the plant operations which have changed what will the . The main concern is that the staff is stretch way too thin. Glenn feels that with all the changes that we have done to the plant we should not run 24/7 and see what the effects in the system will be. Steve S also stated that the other thing which made a difference was slowing down the plant and changing the filling material. Jared stated that he is concerned about water age, in the storage tanks. There was a lengthy discussion about fire reserve. Glen would like this looked at again. John supplied AWs with documentation including everything that was discussed. The different areas where water can be drawn from. There may be a way to lower the fire reserve with a new look at what is available. It was agreed to pilot a 12 hour shift 7 days a week. Tom Keeffe suggested that samples be taken prior to the May 20t" deadline so as to make sure that the TTHM levels are still within guidelines. If not, resume 24 hour plant operations. Nathaniel stated that the main drivers are personnel and costs. Steve sig stated that we are still seeking full time employees. The reduced hours in running the plant are going to be reflected in a lower bill from AWS to Town of Cohasset. All Commissioners are in favor. CONSTRUCTION UPDATE See Attached report from Steve May Glenn wants a system dev. Charged set before Paul Barry puts in his new development in Chief Justice Cushing Highway. Eileen and Tom Keeffe will look into. Sohier Street still closed new valve put in and a new sleeve put in under T track. 3A pump station seems to go out during wind storms. It was suggested to look at a new provider other than Comcast. Tom Keeffe sending a letter to conservation regarding Gammons Road. Final comment from Steve May automatic slide gates at Aaron River and Bound brook are wrong ones and new are on order. American Water Report In Eileen's report 50 meters have been changed and 150 or replaced or repaired. The next billing will show a big reduction in estimated bills. Jared handed out list of gates not included is the additional 76 which have been located in past 2 weeks. Jared Hill also presented the Commission with a chart which shows that if we were to draw water directly from the Reservoir rather than the pond the levels are much higher in the Reservoir than the Pond. Abatements Wheelwright Farm—Pat Monahan CAPITAL BUDGET Hand out by Glenn Operating budget is fine and SRF bills are fine. Out of 4 mill appropriation 285,000 left. 150k due from Erickson. 6k still in from T. Connection fees from Cedarmere and highland estates. It was suggested to amend operating budget of 06 at next town meeting. The timing of when these fees are going to be paid as to keeping things going until new fiscal year. The big project of gammons Road cannot be taken off the grid due to the fact of there would be too man repercussions from the contractor. The project is schedule to be $400k not including Police & Engineering. Suggestions as to how to get more money glenn suggested that Eileen take more careful look at what is being purchased by employees. There was a brief discussion regarding the budget. Next meeting will be e-mailed to everyone by Glenn Glenn went to Cap budget the evening before. They wanted to know what the commission plans on doing regarding Tutela. Town counsel wanted to know if an audit was going to happen. John will pull the original contract with Tutela. Commission will check with Town counsel regarding and audit. Next meeting Thursday, March 30"' @ 7:30 pm Meeting adjourned at 10:50 pm. BOARD OF WATER COMMISSIONERS AGENDA i, Thursday, March, 2006 7.30 pm at 339 King Street, Cohasset 7:30 Budget Review 8:15 Plant/Tank Operations 9:00 Rules & Regulations 9:30 Other BOARD OF WATER COMMISSIONERS MARCH 29, 2006 339 KING STREET, 7:30 PM Chairman, Glenn Pratt Vice Chairman—John McNabb Clerk—Nathaniel Palmer Recording Secretary: Tape Recorder Guests Include: Eileen Commane, American Water Services Meeting commenced at 7:35 pm. ANNUAL STATISTICAL REPORT Unaccountable water on the annual statistical report was discussed. This has been reduced from 41% last year 7.2%. Last year is was due to the master meter and this year it has been reported that it is still high due to the raw water pump. Commissioner Pratt acknowledged that even though the percentage has gone down, he would like to know why it is still so high. Commissioner McNabb explained that the cause could be from broken meters as well as leaks which there are always some. The unmetered water is also part of this factor which includes hydrant flushing. Commissioner McNabb stated that the State regulations state that the percentage should not be higher than 15% which Cohasset has met. Copy of the report is available upon request. BUDGET Commissioner Pratt looked back at fiscal year 2004 when Article 18 was approved at Town Meeting. The monies would be appropriated from the mass water abatement trust. It would be up to the Town Treasurer to get the monies via bonds, which would be paid back by water dept. revenues. It states that part or all of monies, which are to be used for the purpose of system improvements, well fields and treatment plant. This being the case the water commission is able to borrow from this fund. Commissioner McNabb stated then when putting this article together he had a discussion with Mike Buckley and he stated that we would be able to borrow from this fund, but he wanted to wait to see what would happen with the SRF Fund. The Commissioners discussed in length the spending for the rest of 2006, and the effect that it would have going into 2007. If the commission borrows from the SRF there is no delay in payment it must begin after the first month. This payment is not factored into the current schedule for 2007. The Commission will look more in depth to this and report back at the next meeting. In order to borrow from SRF the Commission needs to put together a project before the appropriation is requested. Then the issue is how it will be paid back based on the fact that no new large system development charges are expected. The expected annual payback would be $100,000. If the SRF monies are not used then the money will go to someone else. Commissioner McNabb stated that if necessary a possible increase in rates should be looked at. Other options are to meet with the Capital Budget Committee and see if they have any suggestion. Check with Finance Director Mike Buckley again and rerun projections for upcoming years based on interest rates, and possibly look at short term loans, and draft a letter with DEP with a current plan. The Gammons Road project was then discussed and agreed upon that it would continue. There has been an agreement already made, and to send it out to rebid would be too costly. Eileen Commane arrived at 8:45 and Commissioner Pratt asked for an explanation of the calculations of unaccountable water. She explained that the new format of the form has you start with raw water as opposed to water leaving the plant. She then explained how she calculated the percentage. The raw water meter is a venture it needs a straight line pipe so that it is not accurate and never has been, it has always been a higher amount than it is actually. The pump was calibrated 2 times in 2005. It was suggested that in the future replacing the meter with a Mag meter, magnetic meter. This does not need the straight line to meter accurately. At this point there has been a new affluent meter installed and this is more important. Eileen then said that American Water would be conducting a leak detection program. A sound amplifier would be used. Each fire hydrant would be checked and listened on. Commissioner McNabb asked if this was the suggested way. Eileen stated that it has not been defined. It is a reasonable way to start and use our own people as opposed to hiring an outside company to come in. Another option is to start looking at what the water tank is doing between 1:00— 1:30 am. Commissioner McNabb then brought up the fact that he had spoken to Mary Hartwell of Rust Way and she had a leak. When contacting the Water Department Billy went out and stated that the Water Department does not mark out personal services. This being the case her contractor dug for several hours unable to locate leak, when the Water Department came out again and Barry was able to locate the leak. Commissioner McNabb said that as a customer service we should do this. Eileen stated that if this was to be done that a waiver should be signed. There is always a potential for error since this is not an exact science. The Commission then stated that we should offer to bring out the locator and help, but explain that it is no always accurate. They do not want the homeowner to sign a waiver. Commissioner Pratt then stated that this same thing is what has caused the law suit which between Perrina and P.V. Construction which was just delivered to the town. Commissioner Palmer then mentioned a leak at Herzfelders property. The Department is aware of the leak and received a call from Edith Ford whom is off of the Herzfelders line. The Herzfelders want Ms. Ford to pay for a portion of the cost to fix the leaking line. Commissioner Pratt was under the assumption that the full service was replaced years ago when there was a problem. This will be checked out by the distribution team. Plant Operations Water quality since the plant has no longer been running 24 hours has been fine. The turbitimy has been for the last several months maybe because of the winter, but has been extremely low. No spikes have been seen. Samples have been taken since the change. The volume of change in the tanks has been 10%. There was no turnover in the tanks when running 24 hours. Commissioner McNabb would like to know what are the differences in plant operations 24 hours vs. 12 hours regarding water age in tanks. Eileen will have Jared Hill supply the commission with a report at the next meeting. It was discussed to have the ADT alarm set each night now that the plant is no longer running full time. Each employee will be trained on how to use. The booster station on 3A is not alarmed yet. Commissioner Palmer wants to see that the pump station have a backup to Comcast. The way it is right now thru Comcast we are looked at as a residential account and this could cause a huge problem where we could be without service waiting for a service person to show up. Eileen will check to see if Comcast offers a higher level of service. There was a discussion of the monitoring vs. taping of the different sites of cameras. This needs to be checked. There was a fort removed from Ellms meadow. This was removed before pictures were taken. Commissioner Pratt asked that Steve May be given a digital camera to have with him at all times. Eileen then said she received a request to have the school buses stored at the plant. It was agreed by all that this is not a possibility. Meeting adjourned at approximately 10:00 pm. Respectfully Submitted Brenda L. Douglas Recording Secretary BOARD OF WATER COMMISSIONERS AGENDA Tuesday, April 25, 2006 7.30 pm at 339 King Street, Cohasset 7:30 Update • SCADA • Meter Reading/Billing Cycle • Security System 8:00 Construction Issues • SRF Schedule • Update • Sampling 8:30 Plant/Tank Operations 9:30 American Water • Operations 10:00 Other BOARD OF WATER COMMISSIONERS APRIL 25, 2006 339 KING STREET, 7:30 PM Chairman, Glenn Pratt Vice Chairman—John McNabb Clerk—Nathaniel Palmer Recording Secretary: Brenda Douglas Guests Include: Tom Keeffe, Tutela Engineering, Steve Siegfried, Eileen Commane, Steve May, & Jared Hill of American Water Services, Roger Hill from Highland Avenue Meeting commenced at 7:35 pm. Construction Update Most services now connected on Pond Street. Paving, Loam and seed still pending. Cavanaro: Glenn & Steve met with him and letter with services charges were stated in said letter. Ellms Meadow: Punch list is almost complete. The binder and top coat of asphalt is installed and James Lane I paved. Some controls are not installed yet and landscaping is nearly complete. Tom Keeffe stated that chemical feed system still not installed. Start up results look good so far. Glenn asked if the DEP has come down for an inspection yet. Tom will notify them when start up is expected and then the DEP will do a walk through. Tom stated that start up should be in June. Sohier Street is now open and the main is looped. Hydrant on Sohier Street too high and T won't fix so, Commissioner Pratt asked that Steve May take care of this. There are a few services on Sestito Lane which need to be connected. A new hydrant was installed. Cedar lane has four new services installed; there is still one service #33 to be taken care of. Paving and landscaping are still pending. RH White wants to close out pay requisitions, and the 3A pump station punch list is not yet finished. complete. There was a training session which occurred the previous week. Commissioner Pratt asked about the leaks and Tom Keeffe of Tutela Engineering stated it is outside the contract. Commissioner McNabb asked about the Security cameras, and alarm system at 3A station, Eileen Commane of American Water stated that she met with ADT and they stated a phone receptacle is there but there is no phone line for the system. Commissioner Pratt would like the DEP sign removed as well off of the site. Tom Keefe has a video of leaks at the Bound Brook control structure. The fill is not contusive to holding back water it is the damn. It is leaking from the joints in the block. Tom Keeffe stated that the original contract was for $400,000 which would bring the bridge in to construction for $400k this was under contract, but it cannot be done for less than Imillion. Tom Keeffe explained the different kinds of grout which may be used. Rain Gardens on hold Steve unable to get a response from Norfolk Ram (Mike Clark). Steve will send out a letter if no response. Highland Estates: Steve May has still not received any prints. No work to be done until fees received. Steve will update commission as updates come in. Steve May has also made several calls to Cedarmere and Highland Estates projects looking for fees and start dates, both say within a few weeks. No more permits will be issued until water main put in due to the fire hazard. There are two homes already built and a third foundation has been started. Cameras on tank seem to be working now. Joseph's Hardware water main project will be starting in the next week, T. laria will be doing the main work for the Water Department. Gammons Road bypass is complete and bypass testing has been done, one result received by phone has passed waiting for 2°d to pass. Per Tom Keeffe As of may 1 st the grinding will begin. Roger Hill has been given permission from Sewer Department to put sewer in to his barn. His address is 19A Highland Avenue. There are 3 people off of one line and he was asking if the Commission if they would consider coming down to what used to be known as Brown Court and run a new main so as to give water to the barn and also help the other resident so that they all have their own services. Steve May will check into what the residents would like and get back to Mr. Hill and the Commission. Sampling Commissioner Pratt questioned Superintendent Eileen Commane as to why she thought that the Water Department should do the sampling at new construction sites. Eileen was concerned of the procedures that the Engineering service was using as well as making sure that the chlorine residual is a true sample of the system. Tom Keeffe explained the procedures to all. Steve Siegfried of American Water also had concerns that the contractor has a vested interest to get the sample to pass. Eileen would also like HPC testing done as well as Coli form. The Commission agreed to the changes requested by Eileen. SCADA Engineer Jared Hill of American Water Services completed a cost analysis of the amount spent to date for the SCADA project and what it would cost to finish. Commissioner Pratt was concerned that the original quote was for 153k vs what is now being proposed at 400k. There was a lengthy discussion regarding the upgrades which have been done and what is the minimal amount to be done to run unmanned. Commissioner Pratt would like to hold off the discussion until the next meeting and look at this again. Security system Commissioner Palmer spoke in regards to the security cameras — originally it was decided to just use cameras and rely on the police and do not use ADT. Tom Keefe will meet with Chris Volpe and report to Nathaniel. Nathaniel would like to be there as well and suggested that Eileen and Steve May be in attendance. Tank Operations Fire Reserve was discussed first — John McNabb stated that the original calculation was done in the 90's by Tutela. Commissioner McNabb stated that based on Jared's assumptions as well as calculations from the State fire codes, that Jared should get in touch with the ISO, there was a report written about Cohasset2-3 years ago. Tom Keeffe will get Jared the report and he will contact them directly and report back to the commission. Water age: Water demand was looked at first, then the tank levels & storage as well as rollover of water. Commissioner McNabb was very concerned about the TTHM levels with older water getting into the system. Jared explained that the way the plant is currently running only 10+% is getting turned over in the tank. Commissioner McNabb wants to know what other options would be to keep the TTHM levels low and still turn the tanks over. Commissioner Palmer suggested that if the hours of running are to be reduced then TTHM samples should be taken for the next 3 weeks to check to see what effects this will have on the TTHM results. The real TTHM samples need to by run by May 15t". Commissioner Pratt with Barbara Cook of Weston & Sampson and Tom Keeffe of Tutela Engineering will be meeting with DEP on Thursday to see about borrowing more money. Glenn was finally able to get the most current list of debt from the finance director for the Water Department. Fiscal year 2006 year to date shows that the Department is 189k in the red. Commissioner Pratt would like the h20 bills to go out asap and then do another mailing at the end of June. After further discussion it was agreed that only one billing would be done and that would be done and the end of June no later than June 301", this should allow the Department to have enough funding for 2006. There is still the other option of borrowing, but there is the issue as to how it will be paid back. The options for this were possible rate increase, maybe a betterment charge. The commission needs to take a closer look at fees for inspections and other things that the dept offers free of charge. It was voted to reorganize the Board of Water Commissioners as follows: Chairman: Glenn Pratt Vice Chair: Nathaniel Palmer Clerk: John McNabb The Commission requested that Secretary, Brenda Douglas put together an announcement to notify all Departments. Comments: Commissioner McNabb. received a letter from Mary Hartwell requesting reimbursement for the extra time it cost to locate her service because the Water Department did not get out to her property. John wanted her to be reimbursing 600+. It was agreed to pay her $618.75. John moved to pay all in favor 3-0. Selectman, Ralph Dormitzer spoke to Commissioner McNabb and asked that the Commission consider trying to put money together for Cook Estate purchase. Commissioner Pratt asked that John have him come and speak to all Commissioners. Commissioner Pratt stated that the property owned by Ethel Gormley would be purchased since Mrs. Gormley passed last week. Glenn also stated that David Cogill of Church Street was willing to sell property behind his house, the property was appraised at $60K. Next meeting will be possibly May 2"d Commissioner Pratt will notify all, and Brenda will post meeting. Meeting adjourned at 11:21 BOARD OF WATER COMMISSIONERS MAY 2, 2006 339 KING STREET, 7:30 PM Chairman, Glenn Pratt Vice Chairman—Nathaniel Palmer Recording Secretary: Brenda Douglas Guests Include: Tom Keeffe, Tutela Engineering, Eileen Commane, Steve May & Barbara Cook, Weston& Sampson Meeting commenced at 7:35 pm. Construction Report The Gammons Road project and begun and the street has been ground down. Biszko has laid the temporary bypass and some homes have been hooked up to bypass. Ellms meadow no change a punch list needs to be put together for completion. Cedar Lane last service to be done tomorrow. Rain Gardens are still on hold. Highland Estates: The owner is looking for a 90 day delay in paying the $46,200 fee. Steve May talked to the Building Commissioner and he will not sign off on any permits until the Water Department signs off. There was a brief discussion and it was decided that a letter be sent with the bill that monies be paid prior to construction. There are still two cameras out, the ones at each water tank, due to interference. The lack of capability is due to the interfaces in the SCADA program. The commission would like a motion sensor that when there is motion the cameras will be turned on and an alarm will then be sent to the Police Dept. Other things that have to be looked at are a list of contacts if there is a problem and also who will have access on there home computers to view each site. Commissioner Palmer still needs to meet with Chris Volpe and Steve May, they will look into these options. Joseph's Hardware project will be done by Tony Iaria. He has been given the permits and has been told that the Water Department will supply the pipe. The Standards Sheet was discussed this was put together by Tom Keeffe and Commissioner Pratt wanted to know when this would be used. Commissioner Palmer will review. Once everyone agrees with the format of the sheet it will be given out to all developers to follow. SRF/DEP Tom Barber and Commissioner Pratt went to DEP last week. They were advised to use the money that had been appropriated for the town or it will be given to another town. Glenn then explained how the SRF monies work. He feels that the Commission would be safe to receive 3 million. Barbara Cook then spoke regarding there is still the approval for the original SRF approval. Barbara stated that the following should be put together. Rehab sludge lagoon and possibly add an additional 1 Raw water meter Filter Medias Replace airs cower It was decided that doing the raw water pumps at this time would not be a good idea. Rapid mix motors and shafts Intake improvement: grating would be repaired, sluce gates, run chemical feed lines Motor control center—this should be looked at more closely Approx $826k Barbara Cook will put together a bid for DEP so that the work can be done in the winter FY2007. Tom Keeffe then reported on the construction portion of the SRF. Nichols Little Harbor North Main Whitehead Stockbridge List N. Main as an alternate Buttonwood, Bailey and Ridgetop could also be an alternate Dredging fall of 09 Tom Keeffe will put together bid for DEP. TTHM It was suggested that the site on Whitehead be eliminated from the testing list since it is not lived in in the winter. Levels at the police station were high and Glenn would like the Distribution team to check to make sure that no gates are closed. There could be a possibility that something was left shut due to all the construction. Flushing will be conducted before the final testing is needed. Sed basins are being cleaned out on Thursday Nathaniel has been looking into getting a tower on the Scituate Hill tank for Sprint as opposed to Bear Hill. It was suggested that the zoning and planning board needs to be involved and approve of such an on taking. Tom suggested putting in Scituate hill as an option and putting it in as $3,000 a month charge. Tom will send out the offer to Sprint, Nextel, Verizon etc. Tom will get the list from DTE and see who may be interested. Next meeting scheduled for 6:00 pm, Tuesday, May 30t". Meeting adjourned at 10:20 pm all in favor 2-0. Respectfully Submitted, Brenda Douglas Recording Secretary BOARD OF WATER COMMISSIONERS MAY 31,2006 339 KING STREET, 7:30 PM Chairman, Glenn Pratt Vice Chairman—John McNabb Clerk—Nathaniel Palmer Recording Secretary: Brenda Douglas Guests Include: Eileen Commane, Steve May, Jared Hill, Steve Siegfried of American Water Services, and John Ings and Tom Keeffe of Tutela Engineering Meeting commenced at 6:00 pm Fire Reserve Engineer, Jared Hill for American Water Services reported these findings to the board: The current fire reserve level of 53' in Bear Hill tank was determined from a combination of the 1996 TEA Water System Report and a 2002 Tank Operations Report. TEA recommended that we keep a reserve of 435,000 gallons based on population projections for 2016,plant production, and a fire flow of 3000 gpm. This value was used in 2002 to set the fire reserve level to 53' in this manner: 46.5' = 20 PSI minimum 435,000 gal/66,000 gal/ft(in both tanks)= 6.5' 46.5' + 6.5' = 53' There are several problems with this assumption: 1. The TEA 1996 report was conducted before Scituate Hill tank was designed or constructed. 2. The formula used to calculate 435,000 gallons uses a daily demand of 2 MGD, when our current average demand is 0.7 MGD. 3. The needed fire flow of 3000 gpm for 3 hours is overestimated. After speaking with ISO in detail about various aspects of fire reserve and consulting the Cohasset Fire Department, it is clear that in this case, it is up to the water department to set a fire reserve level for the town. ISO does not provide a recommendation for fire reserve levels or flows, and the quantity of fire reserve does not directly impact the ISO score that is received. Whether or not there is adequate water flow at the particular hydrant being flow tested, is the only fire reserve parameter that impacts ISO scoring. That is more a result of pressure then quantity of reserve, as hydrant flow testing is not conducted for a significant period of time. The AWWA "storage supply required" equation includes plant production capacity as a variable. When the plant is at full capacity (2.8 MGD)the supply required in the equation goes to zero. This is because the plant capacity out weighs the daily demand and fire flow required significantly, regardless of additional sources such as Elms Meadow and Hingham water. However, the plant is not always operating at full capacity and in certain cases may take some time to achieve that production. This is where the fire reserve is critical. The largest water main size in most areas of town is 12 inches. The maximum flow that can travel in a 12" water main is just over 1700 gpm. This is only achievable with several open hydrants at the same time. Assuming that the maximum time it would take to bring the plant up to capacity would be 2 hours, a flow rate of 2500 gpm/2 hours would be more than enough fire flow to last until that time. This would require a reserve of 300,000 gallons or 4.6 feet in each tank. 46.6' = 20 PSI Minimum 4.6' in both tanks = 300,000 gal of storage (2500gpm/2hrs) 46.6' +4.6 = 51.2' in Bear Hill tank (44.7 in Scituate Hill) There was a lengthy conversation with the Commissioners. Commissioner McNabb was very concerned where exactly the formula came from that the fire flow be 2500 gpm. 300,000 gallons of fire reserve. After the explanation was made it was agreed by all Commissions that the fire reserve would be set as follows: 51.2' in Bear Hill tank. Water Age/24 Hour Operations Option#1: 24-Hour Operation Pros: • Water age is lower in the distribution piping. THM results Lower Is'quarter— 2006 compared to 2"d quarter 2006— 53 to 72 respectively. • Facility would be staffed around the clock, leaving an operator on duty in the event of an emergency. Cons: • From the lack of significant turnover this operation creates, the retention times in the storage tanks are long, dropping chlorine residual levels to a point where it is no longer protective of microbiological contamination. • Water age is only lower during the time period when the tank levels have not decreased. Operation cost is increased. • Plant was not designed to run at low flow rates, making operations challenging, especially during months of low demand. Resolving the low flow issue will require Capitol Investment. Option#2: Maximum Tank Turnover Operation Pros: • The storage tanks would be allowed to fill during production and drain when the plant is offline. The hours of operation would be dictated by demand, creating a system where the maximum tank turnover occurs on a daily basis. • The significant amount of fresh water entering the tank on a daily basis allows for the chlorine residual to be maintained preventing a microbiological outbreak. • In the event of a water main break or fire, the sudden tank drain would not fill the distribution system with old tank water, lacking chlorine residual. • Operation cost is decreased. • A tank mixing system would allow for optimal tank turnover by creating perfect mixing within the tank. Cons: • The size of the distribution system (4.6 MG) and storage tanks compared to the average demand (0.7 MG), creates a situation where the water age in the distribution piping at most locations would be greater then the maximum time that it takes for THMs to be fully formed. A tank mixing system would ensure the purpose behind this operation by ensuring that the small amount of water that does leave the tank by fully mixed with older tank water instead of being the last water that entered the tank. Then there was a lengthy discussion regarding having mixers put in the storage tanks. Then maybe not both tanks but at least one. Then if it causes a problem with the THM levels then the tank can be taken off line. The Commission then agreed that Maximum Tank Turnover should be the guide for plant operations. The Commission then agreed that it was imperative to get the plant upgrades done. It was agreed to have the mixers put in both tanks. Tom Keeffe will contact the contractor who originally won the bid to see if they are interested in doing the job this summer. The Commission agreed that the town would run on one tank during the summer if the contractor agrees. Tom Keeffe asked that before he proceeds he would like to sample each tank to see THM levels as well as HAA5's It was also suggested that a HPC sample be done at each tank, which is a bacteria sample. Ellms Meadow Commissioner Pratt wanted to know when it was going to be up and running, also can it be run from the plant. Tom Keeffe explained that the site needed to be manned. Glenn would like Jared to look closely at the way it was to be run as well as what will happen to water quality when mixed with regular water. Manganese, Iron, etc is to be looked at. The tracer study will be looked at again to begin in approximately 4 weeks. The DEP and Board of Health will have to be notified before the fluoride is shut off. Tom Keeffe will begin the process. Leak Detection Eileen has contacted a company by the name of Distribution Solutions and they will be working on the leak detection in the month of June. GIS vs GPS Commissioner Pratt would like the Water Department to take the lead in the town. Commissioner Palmer will take the lead in checking into the best way to proceed. Construction Pond Street - Water pip installation is complete. A leveling coat of asphalt was installed and the topcoat should be installed in a few weeks. The MBTA crossing is underway with water pipe to be installed by R.M. Pacella. Some curbs still need to be installed as well as final grading, loam and seed. Highland Avenue - The Commission agreed to proceed with the project of running a 6" main down what used to be known as Brown Court. This new main will allow the residents to have there own services. Currently 3 homes are off of one line, which runs under one of the owner's basements. Boiler—It was agreed to have the boiler replaced right away since the insurance company condemned it and said it needed to be either fixed, again, or replaced with new. 10 Norfolk Road—Mr, Cingari filed a complaint that the road was put in too high and is now flooding the basement. The berm was removed by a plow truck which made the water drain down the driveway, but the Water Department replaced the berm. Glenn Pratt will contact him directly. Commissioner Pratt reported that the PV construction lawsuit has been settled. Eileen Commane announced that the department received a Notice of noncompliance for 1 S` quarter, the testing was done but the results were not sent to DEP in time. Eileen sent in a letter to DEP and received a response from SE region that we report to know and we were told that if we were under their jurisdiction at the time they would not enforce the non. At the time of the test we were under the NE region so it is necessary or us to supply the town within one year of the non. If it is put in the CCR then it needs to be on a separate form, but it was suggested to send out a single letter. CCR - Karen Quigley is working on the Consumer Confidence Report which will be mailed out in July. Bear Hill Tank - Cameras are still not working American Water has been told that the antenna needs to be higher. American will look into and report back to the commission. Superintendent, Eileen Commane signed with Protection One a contract for the 3A pump station for both fire and alarm system. Engineer, Jared Hill supplied the commission with a cost comparison for which needs to be upgraded in the plant. This also gives a list of what has been done to date to the system. SCADA It was discussed to have the T3 line run, as well as the removal of the Fisher Price Panel so that the plant can run unmanned for 8 hours. This upgrade will be sufficient when the plant expands as well. Waterproofing the control structure—Tom Keeffe of Tutela Engineering will contact Erickson to finish the job and report back to commission. Bottled Water- Eileen Commane will check again with the company to have bottled water done up again. We have been allowed to store water at the Deer Hill School. They would like some of the water donated to sports events. Commissioner McNabb reported that he spoke at a seminar and discussed our buying of land as well as our CCR. He received a great response. Next meeting is scheduled for Monday June 12"' @ 7:30. Commissioner Palmer would like the service agreement looked at for Comcast. Jared Hill and Steve May will look at the agreement and give suggestions to Nathaniel. They will also give any complaints or problems we have had. The commission signed the warrants and they are available upon request. Meeting adjourned at 10:40 pm Respectfully Submitted, Brenda L. Douglas Recording Secretary COHASSET BOARD OF WATER COMMISSIONERS JUNE 12, 2006 7:30 PM, 339 KING STREET Chairman, Glenn Pratt Vice Chairman—John McNabb Clerk—Nathaniel Palmer Recording Secretary: Brenda Douglas Guests Include: Eileen Commane, Steve May, Mike Clark, Kevin Kline & Mark Bartlett of Norfolk Ram, Karen Quigley of Harbor Health, Peter Pratt of the Planning Board & Jim Kinch, Chairman of the Water Resource Committee Meeting commenced at 7:30 pm Avalon Norfolk Ram Group submitted a draft letter to Stephen Pritchard, Secretary of the Executive Office of Environmental Affairs. This was an Environmental Notification for the Residential Development known as "Avalon of Cohasset". The letter must be sent by tomorrow regarding the ENF comment letter (letter available upon request). John has a copy for review for the Commission. Kevin Kline spoke regarding what has been going on the past year. In the past year Avalon has progressed in regards to the treatment plant and excavated a leaching area. The Water Dept. did allow them to use the town water, but since have shut them down due to the fact that they were using the hydrant without permission. Some test pits have been done. Kevin discussed the type of system that they are planning to put in. To date no plans have been received by anyone in town. The membrane treatment system, which is planned, will reduce nitrates. This was a question that Superintendent Eileen Commane had. Now that Cohasset is in the SE region Norfolk Ram feels it will be easier to process. The specs have been sent out for Avalon to proceed and Commission Pratt wanted to know what happens next? Kevin Kline reported that the discharge permit has been filed, but has not been finalized. He will look into further and report back. Kevin Kline then stated that if Avalon does go with a membrane filtration system, which is probably the best treatment process. The big thing that Kevin would want to fight for is that weekly testing be done for influent/effluent VOC bacteria, viruses etc. Commissioner McNabb wanted to know what are the chances the DEP would not give them approval. Kevin stated that there does not seem to be any chance that they will be denied. Nathaniel asked that all of the points regarding things that have happened on the property be written down and document. For instance the fact that no one had been informed of grinding down stumps and field-testing. Commissioner Palmer stated that Avalon has come across that they are doing everything to accommodate the town, and from what is being said they are doing the bare minimum. 21 E Process —Mark Bartlett put together a 2 '/z page conceptual model. The four points are as follows: • Deeper bedrock well should be installed in the vicinity of EMP-11. The well should be extended at least 10 feet into competent rock or to a major fracture set separate from the contact zone by at least 5 feet of relatively competent rock. However, setting he well somewhat deeper would be appropriate and would increase the chances of completing the vertical delineation without any further wells at this location. • A deeper bedrock well should be installed on Howe's Road somewhere near EMP-10, west of the wetland. The well should be extended to approximately 90 feet below grade. • A deeper bedrock well should be installed on Boulder Lane approximately 150- 200 feet southwest of EMP-21. The purpose of this well should be to either confirm that the mafic dike identified by SAIC extends into this area and assess groundwater conditions within the structure or to show that the dike does not extend into this area and provide a groundwater monitoring well more representative of conditions in the "competent" granite bedrock. If granite is encountered the well should be extended at least 10 feet into competent rock or to a major fracture set separated from the contact zone by at least 5 feet of relatively competent rock. However, setting the well somewhat deeper would be appropriate and would increase the chances of completing the vertical delineation without any further wells at this location. If mafic rock is encountered it may be appropriate to install the well in relatively shallow fractured rock. • A deep and shallow well pair should be installed in the "lower parking area" to delineate potential CVOC impacts in groundwater in this area. The Commission as well as Norfolk Ram felt that the impacts of the contaminants on the site should be looked at closer. The report is available upon request and filed under Avalon as well as Norfolk Conveyor Sampling Commissioner Pratt wants an employee of the Water Department to go out with Norfolk Ram next time they do sampling to see where the stream gauges are. The plant is receiving the information, but Tom Keeffe still needs to calibrate the readings. Glenn wants Eileen to check and see what the status is on this. Surface water sampling samples were submitted to lab and should be back in 2-3 weeks. Norfolk Ram reported a change in parameters — they have cut way back on the bacteria sampling also there will be no testing done in the dead of winter. This was done to cut back on cost. This round of samples were the same as last fall, but Kevin will relook at what the patterns are and then relook at the frequency for testing. Bedrock well testing has been postponed; no testing has been done for over a year and a half. Commissioner McNabb wanted Norfolk Ram to test again. The Commission on the Trustees of the Reservation property put in the wells. Glenn asked that Norfolk have 2 employees from the Water Department with them next time around for sampling. Peter Pratt of the Planning Board stated that one of the main reasons for the Planning Board not wanting Avalon was because it deprives Cohasset of business space. Stormwater Regulation Commissioner McNabb would like to put together a workgroup with the Water Protection Committee, Planning Board, Harbor Health Committee, Water Resource Protection Committee, Gulf River Assoc., Little Harbor Watershed Group, Straights Pond Watershed Group, etc. to put together a unified strategy to better control stormwater and runoff in the entire town. Karen Quigley stated that at a Selectman's meeting on 22nd that it was requested to the selectmen that a stormwater committee be put together. Mark Bartlett stated that Cohasset is in good shape as to be in compliance. The first step is the GIS storm water drain locator. Mark suggested that new bylaws or adopt bylaws be implemented. There is a GIS storm water drain locator which the Board of Health has. Peter Pratt suggested that they take the Phase II guidelines and put together a guideline down to a parcel making Peter Pratt wanted to know if it is possible to take the state practices and bring it down to the lot level. He suggested getting in touch with town Counsel. Mark Bartlett suggested if possible coming up with a bylaw Kevin Kline made a suggestion that the bylaw needs to be directed not only to new development but also remedial issues. Raingardens Steve May stated that the garden at the plant was in need of more cuttings as well as modifications to where it is not growing coming down the hill at the plant. Five gardens and a vegetative swale have been put in. There is a schedule to have 50 more raingardens put in around town. There was an extremely lengthy conversation as to the effects of the raingardens. Mike Clark met with Mass highway last month regarding having the raingardens put in on 3A at the intersection of Pond is one site. Mike showed a chart listing where the raingardens would be put. He explained why he decided to do many smaller sites, as explained it gives the town more for the buck. Mike Clark will submit the permit to Mass Highway. The Commission agreed to have Norfolk Ram proceed with the bid process so that the work can be started in the fall. Surface Water Supply Protection Plan Mark Bartlett gave an estimated cost as to what it would cost to revisit and prioritize the changes. See attached memorandum project 651.007.01. The commission requested that Norfolk relook at an update to the SWAP. The commission will have Norfolk back at a meeting to go over all requests from them. Mark Bartlett then submitted a recent 303D list that listed three sites in Cohasset. This could affect future borrowing from the state. Warrant was signed and approved total was $72,000.00 Lagoons Superintendent Eileen Commane presented 4 separate prices for the cleaning of the lagoons. Two of the companies do not have capability of removal. Synagro came in as the low bidder. Eileen supplied a contract that the commission signed off on. American Water Eileen also reported that Simpson Spring can not bottle our water in gallon jugs. The commission decided on getting the 17oz sports size and they would like to have 25 pallets. Eileen needs to check to see where the price break is on the quantity and report back to the Commission. Superintendent Commane also requested of the Commission that electrical work be done to the pumps that have corroded. The Commission agreed that Eileen should proceed with the work. Commissioner Pratt asked that Eileen contact Barbara Cook of Weston & Sampson to see where she is with the SRF project regarding the intake structure as well as the repair of the lagoons. Superintendent Commane discussed the training session that was given last week to the employees regarding the video system. Commissioner Palmer said that the system has the capability to do what we want; we just need to decide exactly what is needed. Currently the system is not connected directly to SCADA. Commissioner Palmer will spear head getting the system up to where it needs to be. Next meeting scheduled for July 5t" @ 7:30 pm Meeting adjourned at 11:00 pm Motion to adjourn made by Glenn all approved 3-0 John McNabb, Clerk Date BOARD OF WATER COMMISSIONERS AGENDA Wednesday,July 19, 2006 7.30 pm at 339 King Street, Cohasset 7:30 Norfolk RAM — Mike Clark 8:00 American Water • Operations • Construction 9:00 Rules & Regulations Other BOARD OF WATER COMMISSIONERS AGENDA Wednesday,July 19, 2006 7.30 pm at 339 King Street, Cohasset 7:30 Norfolk RAM — Mike Clark 8:00 American Water • Operations • Construction 9:00 Rules & Regulations Other Agenda Water Commissioners Meeting August 9, 2006 6:00 pm 6:00 Sohier Street Wells - Hoffman 6:15 Rain Gardens - M.

There are plans to revamp the field as well as do some drainage work. Glenn asked that Mike contact BSC group who is in charge of the renovations. Mike supplied a list of potential areas for future gardens, (list attached). Mike would like to have one or two meetings possibly splitting up the group. Some of the areas are on personal properties with easements. Mike was asking how the Commission would like him to proceed with contacting each homeowner. There was a brief discussion and it was decided who and how they would be advised. A letter from the Commission will be sent first stating that Norfolk Ram will contact them directly and come out to see them. The Commission asked that Mike get the bid out by the end of next week. This will include the large gardens on 3A and Pond Street. Commissioner McNabb reported that he is getting great feedback from many groups regarding the gardens. Reservoir: Commissioner Pratt read a report from the Fire Department regarding the incident which occurred at the Reservoir on July 31, 2006. The report states that on 7/31 dispatched to Aaron River Road to a woman screaming for help from the water. Report stated that she went into water to get her dog and was unable to get out. Fire rescue showed up and got the woman out and brought her back to her vehicle that was on Mt. Blue Street on the Norwell side. Resident David Stover of 533 Beechwood Street stated that if the Fire Department had got into the Reservoir in a different way it would not have taken them 20 minutes to get the boat in the water. Another resident, Martha Narten of 20 Church Street, stated that she wanted the Commission to consider opening up the end of Beechwood as well. After a discussion with the residents that attended all Commissioners were in agreement that the reservoir gate at Aaron River will again be opened. The residents then tried to get the Commission to open up the gate at the end of Beechwood. The Commission was not willing to open up the gate at the end of Beechwood. Commissioner Pratt asked that Steve May open the gate at the end of the meeting. Construction Update (Steve May, Construction ManalZer) Pond Street- Awaiting paving to be done. Sestito Lane is complete and it is being rechlorinated once it passes it will be turned no. Cedar Lane is also complete Gammons Road is about 90% complete. Construction has ceased at this time due to the fact that a resident is having a wedding. Cedarmere: Planning Board meeting scheduled next Wednesday which Steve May is planning on attending. Glenn would like Steve May to write a letter on behalf of the Commission stating that they do not want construction to continue until fees are paid. Ellms Meadow Pump Station: The floor has been painted, locks are in and the new shelving has been order. Eileen stated that she needs an O & M manual for the station. She has spoken to Tom Keeffe of Tutela Engineering Services on numerous occasions. Once the staff has been given direction as to the way that the station is to run, Eileen will put a report together for the Commission as to the planned operation. 3A tap to Joseph Hardware: Tapping Sleeve has to be specially made. None of the companies, which have been contacted, have the appropriate size. Plant Upgrades: Steve will put together a cost analysis on the savings that the new boiler will give to the plant. Superintendent Commane will set up a meeting with the Board of Sewer Commissioners and Dan Coughlin to let them know that the Water Department is planning on putting in new water main on Little Harbor and to see if the Sewer Department would like to put in their main at the same time. This would alleviate digging up the road twice. Video surveillance meeting: Commissioner Palmer said that the problem lies with the installation done by LeFleur Electric. Nathaniel stated that there were several changes made to the surveillance cameras. He will work to get things up and running properly. American Water Operations: Superintendent Eileen Commane reported the following: Flushing was completed in mid July. An order was received the office of dam safety for an updated inspection of Aaron River Reservoir Dam by September 30"' along with an Emergency Action plan. Weston & Sampson Engineer, Mark Mitsch, will start the work in a few weeks. Manganese levels rose dramatically in July causing 38 discolored water complaint s to the office between July 11`h to date. Electrical interlock installed between finish water pump motors and Golden Anderson Control valves. Chlorinator system broke down, cleaned out and preventative maintenance performed. Erickison/Aquarion — Interconnect pumping is being matched at a rate of 60,000 gallons per day effective 8/8/06. This is an increase from 40,000 gallons per day when we trued up with Aquarion three months ago. SCADA — We have received pricing from two contractors, LaFleur and HiVoltage, we continue to wait for estimates from another electrical firm: Fall River. Ellms Meadow—Work progressing. Video feedback is now established. Phosphate Corrosion Control — Weston & Sampson will be submitting permit application to DEP for polyphosphate addition, which has more suitability for manganese control. GPS kickoff meeting was held on August 3rd with Commission Palmer, the staff and Environmental Partners, Tutela and Norfolk Ram Group. Video/connectivity meeting was held on August 8 with Commissioner Palmer, staff, tom Keeffe, Chris Volpe, John deWaal, Paul Oullette and Craig Finley. Kevin Klein of Norfolk Ram reports that levels of a metal, Thallium were detected at one of the Trustees wells. They are planning on retesting the site. A request was sent to DEP to change the THM sampling locations from the current location to Police Station, Starbucks, Deer Hill School and Cohasset Harbor Inn. Testing for a pesticide, Benefenthrin, recently used at the Beechwood Cemetery, did not get detected on any of the material. Massachusetts adopted new regulations for prechlorate, setting an MCL of 2 ppb. Prechlorate is often found in explosives and can cause thyroid problems. Eileen also reported that Caren Wheelwright, the part time administrative assistant resigned on August 3Td after only two months. The position has been posted again and she expects to have it filled shortly. In the meantime a time will fill in until someone is hired. Bruce Meehan, Plant operator has started full time, and part time meter reader Barry Bennett is back. Eileen explained that the chlorinators have been causing problems. The commission wants Eileen to replace the system using gas. The manganese war water levels escaladed during July and remain elevated. The DBP's have been in compliance for the last two quarters of 2005 and first quarter of 2006. Results continue to be good. The levels of TOC and UV are a current concern. The pilot study continues and the date is being compiled. Summer sampling began this week and will conclude the last week of August. Intermediate ozone/BAC pilot started in February and concluded in early April. To reduce the manganese the plan is to switch to sodium permanganate. Weston & Sampson will be submitting plans and a permit application to the Southeast DEP Region. Commission wants the plant to run 24 hours a day for several days to help with the TTHM levels. Once this is done run the non reg tests in the system if all looks good then run the regulatory testing. Lime feed proposal: Suggestion from Jared Hill and Eileen Commane is to go with R.H. White. Commissioner McNabb would like more discussion regarding this project. It will be brought back up at a future meeting. Erickson: Eileen reported that 20000 being sold a day. Tank mixers: Hemi will install the original price to install the mixers was $73,000 after waiting 2 year he now wants $88,000. Hemi is the contractor. Steve May stated that he would contact the contractor to schedule a date to start. The town wanted Old Road abandoned which has been done and Glenn had the order of taking for the Boards signatures. All commissioners signed. Commissioner Palmer spoke about GIS vs GPS, he has Environmental Partners looking at getting a rough draft of a workable GIS system. Commissioner Palmer is also looking at the evolution into GPS. Nathaniel made a motion for all future and outstanding work be withheld until we receive as built drawings and electronic format. This will be specified and voted on at the next meeting. Change orders were submitted for the Gammons Road project that the Commission signed off on. This was for the addition of 3 homes to be added. Warrant: Capital Projects: $451,753.89 Various General Expenses: $108,688.53 SRF2: $111,804.58 General Operating Expenses: $14,983.49 All were signed off on and approved for payment. Abatements: A total of$24,757.47 was signed off on and approved for abatement. Next meeting scheduled for 8/23 @ 6:00. Adjourned at 9:35 pm John McNabb, Clerk Date Minutes of the Water Commission Meeting August 23, 2006 339 King Street Glenn Pratt, Chairman Nathaniel Palmer,Vice Chairman John McNabb, Clerk Recording Secretary: Brenda Douglas Guests Include: Eileen Commane, Steve May, Jared Hill,Kevin Klein of Norfolk Ram, Tom Keeffe and John Ings of Tutela Engineering and Barbara Cook of Weston& Sampson Meeting commenced at 6:00 pm Manganese Commissioner Pratt asked that everyone give ideas on how and what is Manganese. Kevin stated that it is another form of iron. It is naturally occurring. Coming in 3 forms soluble particulate and semi oxide. Usually in a plant that does some sort of oxidation it will remove it. Usual ways to remove would be sand filter or permanganate. The organics need to be removed. Barbara Cook stated that a lot of plants which draw from the same type of water find a higher manganese level in the summer do to the warm weather. Oxidizing the water will make the manganese more soluble so that it would be able to be filtered before leaving the plant. Terbitemy has risen with the manganese level. The reservoir turns over with the change of weather, whether it is winter or summer. This could account for the high levels in winter as well as in summer. The plant does not have the capability to have enough contact time to remove all manganese. Barbara Cook submitted a report on defused air system. The town of Danvers had this installed. What it does is add oxygen to the pond prior to in going in the intake. The Commission wanted Barbara to get more information ie, will this disrupt the bottom of the pond since it is so shallow. Barbara also plans on checking with other town whom have implemented this system to see if it really works and what might be some repercussions to this system or negative effects The commission then wanted to know how the MIAX study was looking in regards to removing the Manganese. Barbara Cook and Jared Hill stated that it did reduce it a lot more that what was currently being removed. There was a brief discussion regarding green sand. This would require a new filter bed, but it would remove all iron and manganese. Barbara Cook stated that the cost would be at least 1 million dollars. Glenn then asked is there is one treatment process to alleviate all problems what would it be. Barbara Cook stated that there is not one treatment that would take care of all with the exception of nano. This would remove all,but it is extremely expensive. The commission requested that Barbara get names of other towns, which have used the defused air system. She will make sure that there are other towns that have used the system and will ask if what exactly it helped with and if it had any negative effects. TTHM Jared Hill presented the board with extensive breakdown of levels from 2004 till now. There was a lengthy discussion on how to lower the levels again. Jared is going to run different scenarios on the treatment side to try and lower the manganese. He will run jar tests to see if the PACI and Ferric Chloride. Avalon The Commission asked Kevin to send a letter to the DEP to get a copy of review the soil reports from the site. Kevin spoke with a person from Avalon and they said that they would not supply one. Kevin stated that this is a public record and there should be no reason for a copy to be given. Commissioner Pratt spoke of a meeting that he and Commissioner Palmer had with the Sewer Commission today. John Beck was the only member there but Dan Coughlin was in attendance. The Commission would like to work in conjunction with the Sewer Commission putting in their pipe when we replace the water main down on Little Harbor Road. This will alleviate digging up the road twice. Commissioner McNabb stated that he got a call back from the Globe and they stated that they would rescind the report of Cohasset being out of water. Commissioner McNabb also reported that on Monday night at the Selectman's meeting they were going to see about putting together a committee. A motion was made by Nathaniel Palmer to abandoned Sohier Street well was made by this was seconded by Glenn Pratt all in favor 3-0. (John was sad). American Water presented an agreement to do the plant upgrades to the Lime system. A copy is available upon request. The commission all agreed and signed off on the contract. Next meeting September 7, 2006, 6:00 pm . Meeting adjourned at 9:15 John McNabb, Clerk Date BOARD OF WATER COMMISSIONERS AGENDA Thursday, September 7, 2006 6:00 pm at 339 King Street, Cohasset 6:00 TTHM Results 6:30 Update GIS/SCADA 6:45 Rules & Regulations 8:00 Operations/Construction Reports 9:00 Other Board of Water Commissioners Meeting September 7, 2006 339 King Street Members Present: Glenn Pratt, Chairman Nathaniel Palmer, Vice Chairman Recording Secretary: Brenda Douglas Guests: Jeff McIntyre, Eileen Commane, Steve May all of American Water Services Meeting commenced at 6:00 pm. TTHM Results Eileen reported with a spread sheet of the TTHM current running annual basis. Average this quarter was 83. Last year was 69, so the 69 was dropped and the 83 was put in. American tried to lower the Ph but it was difficult to do that and get good coagulation. American also ran out of ferric chloride, but that did not seem to make any difference in the removal of the manganese. Superintendent Commane consulted with Barbara Cook of Weston& Sampson and Oran Snyder of AWS. Neither had any more suggestions of how to reduce manganese using the combination of Pac and Ferric. The approval of the change in testing sites has been agreed with the DEP but the Deer Hill and Osgood will be on the list, but the Deer Hill being the regulatory site. The Cohasset Harbor Inn will replace 100 Whitehead. Commissioner Pratt questioned the areas which are the sample sites. He wanted to know why the two sites of the Police Station and Cohasset Harbor Inn. Commissioner Pratt suggested doing some testing at Forest Avenue and Jerusalem Road. Commissioner Pratt would also like samples done at Red Lion Inn and Bates Lane. Commissioner Pratt wanted to know if putting Ellms meadow on line might help with the results at the school. Eileen explained that there was no ability to put Ph into the system and this is an issue. There was a brief discussion and Commissioner Pratt wants the pump station to be used and see what it will take to get it running with the Ph in place. Preventative maintenance was discussed, Commissioner Pratt would like some sort of maintenance program for the plant put into place. The Commission requested that Brenda get the bill stuffer for the upcoming water bills be put on glossy paper. This should give it more attention with the bills. Jeff suggested that the Board of Health Agent put in something that states ie. This is not a heath issue..... Commissioner Pratt said that in the future they would look to contact Joe Godzik, of the Board of Health for some possible insight. GIS/GPS Commissioner Palmer and Steve May suggested that Environmental Partners oversee the GIS system they will keep the information off site. The start up cost was 25,000-30,000. Commissioner Palmer suggested investing in GIS system. We would buy access to a system. Environmental partners would host the system. This would be at a one time cost. We would pay a fee for updates to the system. An example of how this would be done is if we had a completed set of as- builds we would send it onto Environmental Partners and they would update. Commissioner Pratt wanted to know how much it would take to put what we currently have and put it with Environmental Partners. Commissioner Palmer stated that Norfolk Ram might want money to release what they currently have which may or might not be useful. It might be advantageous to simply have Environmental Partners come in and start from scratch. Commissioner Pratt stated that what Norfolk had done a few years ago was completely useless. Glenn suggested telling Norfolk Ram that Environmental Partners would be doing the GIS and simply send us the information which they have currently. Once GIS is implemented then GPS would be implemented. There is equipment which is associated to GPS. The equipment would require someone to go to each service, valve, shutoff and key in the information. This would then be downloaded/uploaded. Environmental Partners said that it was possible to do 100 a day. Environmental Partners would train the person or persons on the GPS unit. Commissioner Pratt requested that Commission Palmer contact Environmental Partners tomorrow and get project going. SCADA Superintendent Eileen Commane supplied a project report with the status of SCADA. It was suggested to get an electronic engineer who can oversee the programming. Jeff McIntyre will get a list of names to Commissioner Palmer of contractors who might be able to oversee the project. What the Commission is looking for is "an owner's engineer review". Rules &Regulations The discussion has been put off until Commissioner McNabb can attend. A copy will be sent to Jeff McIntyre. The commission has requested that Jeff give any suggestions that he may have. Operations/Construction Reports Superintendent Commane reported the following: Flushing was conducted on Friday, September 1 in response to numerous discolored water complaints. There were 90 discolored water complaints between August 1 to present. Finish water manganese levels have dropped considerably over the last two weeks. Presently at 0.08 mg/l. THM sampling on August 30 resulted in an increase of the running annual average to 65.5. An order was received from the Office of Dam Safety for an updated inspection of the Aaron Reservoir Dam by September 30 and Bound Brook Control Structure by December 15th, along with an Emergency Action Plan. Weston and Sampson engineer, Mark Mitsch will perform the work. Filter#3 valve was out of service for two weeks. After rewinding the motor and having an electrician check out the wiring, Jim Law, an instrumentation technician traced the problem to a contactor that was part of the Fischer Porter panel. He replaced the part with a dual relay/electronic contactor. The filter is currently being disinfected and will be returned to service tomorrow. There was an operator error which resulted in addition of chlorine to the plant effluent line after the high lift pump was shut off on 8/30. The chlorinator must be manually shut off when the pump is shut off. The problem was discovered and the pipeline flushed out. The interconnect to Erickson/Aquarion is being matched at a rate of 60,000 gallons per day effective 8/8/06. This is an increase from 40,000 gallons per day when trued up with Aquarion three months ago. A rate increase will be tied to MWRA rates in November. There was a training session at Ellms Meadow on 8/23. The vacuum priming system was not operating properly. Weston& Sampson will be submitting a permit application to the DEP for polyphosphate as an addition to treatment for the plant. This should be more suitable for manganese control. Steve May, Construction Manager reported the following: Pond Street is ready to pave and RM Pacella will put in new water main with the MBTA this week. On Gammons Road most of the services are installed. Road grindings were installed on the Genovese branch of the Road (130 Gammons Road). The Cedarmere project has stopped. Commissioner Pratt and Steve went to a meeting with the Planning Board and explained that no fees have been paid by the project. The fees need to be paid prior to water being given to the project. Steve May sent a letter out regarding Highland Estates regarding the water main not going all the way to Castle Lane, copies were sent to the Planning Board. Highland Estates: Glenn spoke with Town Counsel Rod Hoffman to see about having something typed up to the fact that a lien would be put on one of the properties if they are not willing to extend the main back to Castle Road. The lien would be removed once work is complete. Joseph's Hardware new line is complete and the line to the Village Greenery also on 3A is waiting for the service connection. The new boilers have been installed in the plant and the old boiler has been removed. The installer should start up and test by Friday. The new garage doors are installed and the electric has been complete. A pre bid meeting was held for the Rain Gardens with only one bidder picking up documents and plans, (Chad Sumner from ComCo). Richard Keith from DEP was in attendance. The Town of Cohasset is trying to extend the Northern Construction contract to include Elm and Brook Street. Steve suggested that the commission should consider replacing all services on those streets prior to the start of construction by the town. Steve is also getting prices for replacement of water main and will call for more quotes on water services. A meeting was held on 8/8/06 regarding cameras on communications. Attended by Steve May, Eileen Commane, Paul Ouellette, Jared Hill, Tom Keeffe, Craig Finley, John DeWahl, Chris Volpe, and Nathaniel Palmer. Items discussed were communication issues, PIR vs Pixel motion, modems and routers, insects in the cameras, night vision, cable, phone lines, and wireless connectivity. There was an agreement made to repair, replace components and solve the issues at hand. RH White is scheduled to start installation of the new lime feeder on September 11, 2006. The exterior plant light was fixed. All exterior bulbs were replaced and four wall packs were replaced as seven lights were not working or burned out. This should help with the camera situation and the limited lighting. 3A pump station. Trees are being installed due to the fact that the trustees which the land was taken from stated that a green lawn will not suffice. The monies from the Ellms Meadow yard care is being brought over to 3a pump station and Sestito will put in trees. The commission wants Karen Quigley to put together a kid's friendly flyer. Eileen will contact her directly. Brenda requested that the commission credit the 90 residents who complained of dirty h20 over the past 2 weeks 100 c/f on the next billing. Brenda suggested that it would be good pr as well as people did have to run excessive water to clear the lines to their homes. Both commissioners were in favor. Beechwood Street Bridge: This must be fixed to meet with our water withdrawal permit. Glenn wanted to know if Erickson should be held accountable or should we fix the bridge at the cost which was quoted by Tom Keeffe of Tutela of$85,000. Steve May and Commissioner Pratt attempted to work with the Sewer Department in regards to the new water main going in on Little Harbor Road. The Sewer Department is planning on eventually putting everyone on town sewer. The Commissioners thought it might be a good idea to work together so as to only dig up the road once. The meeting did not seem to go so well. Dan Coughlin, engineer for the Sewer Department totally against working with the Water Department. One reason he gave was that it will increase the betterment 150.00 a year. So it looks like they will not work with us in regards to putting in new main. Land Purchases Glenn supplied everyone with a copy of a spread sheet listing parcels which have been bought; second sheet is parcels which the owners cannot be located. So Glenn stated that the land will be taken. The third page is a listing of parcels pending, (a copy is attached).

Glenn and Steve met with them and they stated that they wanted to pay as at they go. Glenn stated no, possibly in a phase stay. They stated that they wanted to line to go up to Castle Road. After they met with Glenn and Steve they also went to the planning board and said that the Water Department said it was ok when it was not. This was also put in the papers. Scituate CPC The Robbins are stating that they want another 25,000 from the Department. They suggested giving it to Maxwell Conservation. Highland Estates: Glenn recapped to John what has happened in the past couple of weeks. Ie: they wanted water, Steve said where's my extension of main. This created several problems. Before you get water for the last two houses. Everyday Steve has received calls requesting the water to be turned on. Two nights ago Steve and Billy found a truck on the property and also found a hose from the house next door and was supplying the main with water for a pressure test. Billy shut it down again. On 9/21 both Glenn and Steve went to lawyers office to file against the contractor. They then agreed to hold back on water on the last 2 properties until the extension is done. Cali Glenn met this week with Cali Corp. and Cali called in DEP (Jack Ham). Glenn ended up signing off on the change order and Cali will be paid the $3,000 as requested. Lime feeder project is underway and they will continue on Monday Grinding of the roads to start next week and paving the next. Bound brook bridge: they said get the proposals in for the suggestions on how to fix and then send it out for bid. Ellms meadow: There is still the concern of he ph. Right now the levels are fine, 6.5, but if it lowers there may be some concern. Eileen feels that 6.5 would be the lowest. The water in the system is 7.5. This is raised with lime. How much would it cost to put a third system in, the commission wants it looked at. John Hallan arrived regarding something?????This included the P&S and the Conservation Restriction. This was for the review of the commission. The town of Scituate delegated 595,000 and the Cohasset h20 commission stated that they would give 100,000. Glenn suggested that Scituates town counsel contact our counsel directly and let them figure out the correct writing of the contact. He also wanted to know if there was an additional 25k available to help out with the closing cost. He wanted to know if there was additional funds available to give to Scituate. He felt that there was an agreement that if there was a shortfall that Cohasset would give additional funds. Glenn said that they would take it under consideration. John stated that none of the monies would be going to the town directly that the monies would go directly to the Maxwell Conservation trust. The selectmen as well as residents feel that Cohasset did not get involved with Scituate but only to the trust. DEP Update SRF Settlements Change Order for rock blasting on Gammons road for contractor L. Perrina was signed and approved by both commissioners. Warrant Signed and approved—Copy available. Planning Board is holding up the committee for the stormwater mgmt. All other boards have appointed their individual people. John stated that the board wanted Bob Sturdy and not Peter Pratt.

The board was on a fact-finding mission. Due to the fact that we are not lacking water, we have open space, as well as the commission has taken a stand in regards to Avalon. 40b requires 10% or 280 units. Tom stated that with Cedarmere, Avalon, 3A project they will be pretty close. Tom asked about the property out back of the plant, which the commission has purchased for development. Commissioner Pratt explained that because the monies used to purchase the property was grant monies that the land would not nor could be developed on. Tom also asked about the land across from the Gold Star mothers memorial as well as the land behind Fox run and back up the memorial school. The land across from gold star mother's memorial is cemetery property and there were issues in the past that the town did not want to get involved in selling or swap the land. The other does have some issues one of which is watershed land affiliated with it. The commission would not stop development but would be cautious when developing. After a lengthy discussion the Housing Partnership thought that the town land behind the Memorial School would be best to be looked at for development. Mrs.Erdman—439 King Street Brought in samples of her water and wanted the commission to give the type and name of a filtration system which will remove the manganese from the water. Commissioner Pratt asked if Mrs. Erdman would be willing to let us install a filtration system and test it out. If possible maybe several. She was very willing to help out. Steve May will go to her home the next day and set up a time to come by and check the pipe. Anthony Nader—Highland Estates Nadir said he contacted steve in regards to putting water in the main. Steve said that the water needed to be certified. They went back and forth it was a pissing contest. Glenn stated that there was a violation and the fine is $1500. There was no need for any discussion. Technology - Nathaniel GIS/GPS Environmental Partners (check out print out) Agree to move to fist phase which is to get basic requirements which allows us to find out what we have and find out what we want. This would be the most cost effective way. Nahtaniel is very comfortable on moving forward Phase 2 Nathaniel has not spoken to Norfolk or Tutela yet and he will wait until phase is complete Phase 3 Glenn requested that the gps unit be purchased so that we can start gathering the information needed such as: services, shut offs etc. SCADA: Several proposals have been received regarding having someone look at and evaluate what we have projected. Security system: met with volpe again. Final proposal includes clean up and pir additions.. Steve told him that the quote for 15K included some things which should have been completed before, but is still not done. Steve is looking for a revised quote. Meters: John will have Margaret McCarthy come in and give the information regarding the new meter reading systems. Drew is gone. And our new chief operator is Bruce Meehan Eileen told the Commission that American Water tried to coat the filter media with PAC. We followed the procedure explicitly and it had no impact what so ever. American was very hopeful t hat it would give a reduction but it didn't. Eileen stated that next Tuesday the 17`h a meeting with the SE DEP, and DEM will be held at the plant to discuss all permit requirements. Steves Report See Attached There is a Stormwater committee meeting tomorrow night. Estimate from Mike Clark of Norfolk Ram Group for the cost from now till may what the engineering costs will be and how the monies will be divided up.

Still working on curb for the end of Pond St. and replacing side walk. This is being paved this week. The Town of Cohasset is trying to extend the Northern Construction contract to include Elm and Brook St. We should consider replacing all services on those streets prior to the start of construction by the town. This has now been approved and we are getting prices on changing the services on those streets from the main to the curb boxes. Also I am getting price for replacement water main. Elm and Brook St. services are done. A meeting was held on 8-8-06 regarding cameras and communications.

Jared P Hill/AAET/AWWSC To Stephen C May/AAET/AWWSC@a AWW 1 0/1 1/2006 09:37 AM cc bcc Subject WTP Sewage/Drainage System Steve, I wanted to share with you a few of my thoughts about our meeting with Ross Rosano regarding the plant sewage/drainage system. The current system that we have is not acceptable for this main reason: all of the drains in the treatment plant,floor, analyzer, and laboratory, eventually drain to the sump under the stairs which is the same location as the bathrooms drain. This is mixing process drain water with sewage. In the event of a sump backup,from either a pump failure or a flood in the plant, this cross connection would lead to sewage on the pump room floor,with a possible contamination of the clearwell. This was brought to our attention when the sewer line that connects to the street was broken. Disabling of the pumps lead to a back up of the floor drains on the treatment plant floor. New pumps were installed as one of the old pumps was beyond repair and the other had electrical issues. The new pumps, while the same size as the old ones, provided more force on the discharge line (which had been improperly labeled drain)and caused the line to rupture. This line runs the length of the pump room, directly over the clearwell hatch, and outside into what was an old leeching field. There is now an Interon pump outside, but this is the last line holding back all of the sewage from the street. If the check valve failed on that pump the area outside would become flooded with sewage. Seeing as we do not want to move these plant drains to the wastewell, as this creates more liquid sludge outside, costing more to remove,we need it to continue to feed the sewer. Ross had some very good ideas about putting new sumps outside and obviously seperating the sewage from the plant drains. This would eliminate the back up risk on the pump room floor and abandon the pipe that runs the length of the pump room. Not sure why it was designed that way in the first place. While I do not know of any specific DEP regulation off the top of my head, I would assume that this would be something that they would make us fix if they were aware of it, and it could be something that they address on future Sanitary Surveys. I will look up specific regulations when I get a chance. Thanks. Jared Hill Operations Engineer American Water Services 781-383-0057 x104 Suggested Discussion Points Cohasset Boards&Committees ♦ How much emphasis should Cohasset place on creating affordable housing that counts on the Chapter 40B Subsidized Housing Inventory?(See next page for current HUD Income Limits and estimated affordable sale prices.) Should the Town focus on "affordable"for somewhat higher income groups that have been priced out of Cohasset,or on creating units that help the Town progress toward the 10%statutory minimum? Or both? ♦ What do other town boards consider to be realistic options for creating affordable housing in Cohasset? Realistic for: ♦ Chapter 40B affordable units ♦ Other affordable units ♦ What would constitute the"ideal"affordable housing development in Cohasset? (For example: small developments,upper-story units in commercial buildings, homeownership units,rental units, developments of any size that pay careful attention to architectural design, etc.) ♦ .What locations make the most sense to consider for affordable housing, given that a mixed-income development will most likely involve greater density than allowed under Cohasset's present zoning? ♦ In most towns,Housing Partnerships typically serve as the initial point of contact for developers interested in proposing an affordable housing development. From your board's point of view,what should we be communicating to prospective developers? What is the most important message you would want them to hear? ♦ What kinds of public information or public education strategies should the Housing Partnership consider to build support for providing affordable housing? ♦ If the legislature decided to rescind Chapter 40B, should Cohasset still pay attention to affordable housing needs or is the main goal to reach 10% (if possible)?

It was agreed to abate $450.00 Water Management Permit/Regorting Eileen received a call from Leslie O'Shea from DEP looking for 2005 report from stream gauges. Eileen pulled out permit and found there was a requir4ement but Eileen was not aware of it. Eileen said some of the data was done but not until April or may was it written down. Reservoir is now being tracked. Bound Brook: It is now being field measured. Glenn wanted to know if the stream gauge that Norfolk ram has in place at Bound Brook and does this do what we need. Eileen says no. Glenn conveyed his aggravation due to the fact he was under the understanding that all sites were working. Eileen stated that Doane Street is working, Bound brook not working will be working once Comcast is hooked up Peppermint Brook no working due to the fact that the radio antenna is facing the wrong way. Brass Kettle does not work due to the fact that the battery went down and they are looking for a solution to only transmit once a day to save on the battery. Glenn wanted to know why we can't put phone or cable out at the site. Tom stated that the site is too remote to do so. Glenn wants a letter to go out the DEP and told Eileen and Tom to give them what we currently have and then show them then tell them in order of things getting fixed. Tom Keeffe presented to the Board a draft of a letter to Leslie O'Shea from the DEP. Eileen stated another thing that needs to be done is a letter needs to be sent out to surrounding towns regarding permitting around the reservoir. Eileen will get he letter template and give it to Commissioner McNabb who will intern get the letters out on behalf of the commission. Tom Keeffe also submitted to the Board another Condition: the Water Audit of Public Buildings: Out of all that were inspected Tom reported that he had no information on the Water Department. Glenn suggested having the toilets replaced with low flow. Both reports are attached GIS/GPS & Scada Nathaniel is meeting here on October 31S`at 9:00 am it should run approx. 2 hours. Nathaniel requested that 2 member of AWS attend. Eileen will contact AWS and find out what there suggested GIS/GPS system would be. Security: Steve reported to having several more meetings with Volpe. Volpe has submitted another proposal for$14K to fix all the problems with the cameras we are having. This would include more lighting and not the replacement of new cameras. Glenn wanted to be advised if the commission should go back to Volpe and salvage what we currently have or simply start from scratch. Everyone in the room gave their suggestions and it was agreed by the Commission to "check with the school system to see how they like their system. With that getting something in writing including getting rid of pixels. Jared suggested that each site be looked at individually ie: the reservoir has one sensor and that will just look at the intake. If additional areas are to be looked at additional sensors will be needed. All were in agreement. This will be brought back up at the next meeting American Water Operations Report (Eileen Commane)—Report Attached Manganese: Glenn brought up the issue of the manganese. In the packet this week was a letter from Mr. &Mrs. Curran of Beechwood Street, which stated what the consensus was throughout the entire town. People are unable to use the water but are forced to pay for it. It is staining clothing as well as stained toilets and tubs. The Curran's have just renovated their home and their new toilets and tubs have been stained. Glenn stated that he looked closely at his laundry and found that he was having the same problems at his time. He stated that this is unsatisfactory at this time. John wants a list to be compiled from Jared with what we have done and what are possibilities, pro &cons. The commission suggested that Eileen go to the Curran's home and look at their filtration system then The new procedure is that when a DW call comes in to send someone directly out. Steve's report: Egg beaters: john wants to see sample points within the tank. Jared and jeff suggested a chlorine analyzer at the input and output lines in the chamber. The commission had a discussion regarding send of money of 25,000 to the Town of Scituate to help with the sale of the Maxwell property if this is done then 25,000 will need to be sent to $25,000. This will be tabled until next meeting. Due to the fact that there is another property, which is coming up for, sale and the commission would like to help out with this as well. The original amount given at town meeting was $250K and the commission felt that they would give 125K for each sale in Scituate.

Norfolk Ram and our office. At the meeting, various issues were discussed and it was agreed that a letter would be prepared and submitted to describe the Cohasset Water System's status and plans regarding select reporting requirements of the May 20, 2005 (commented and revised July 27, 2005) Water Management Act Permit /#9P4-3'21'O65.U1\ that are related to fish ladder and stream gauge stations, land use control and public building. The Cohasset Water System is also subject to other permit reporting requirements beyond those that are described hereafter. The meeting also provided 8D opportunity tO assist iOthe transfer Of information regarding the COhBssetVV8ter System from the [}EP Northeast Office to the Southeast Office. The permit issues discussed 8t the meeting included the following: * Special Condition #5 Surface Water Protection. The Water System shall submit any existing land use control. ° Special Condition #7 Seasonal Flow Releases and Drought Management Plan. The Water System shall maintain releases indicated and implement the drought management actions based on the conditions present. The Water System shall also implement stream flow monitoring plan. ~ Special Condition #10 Water Conservation/Plumbing/second bullet item. The Water System shall address and report the status of water saving devices in public buildings and implement a retrofit program, if needed. ° Special Condition #11 VVotmr Use Restrictions. The Water System shall institute water use restrictions indicated in the [}[Ought Management Plan and report all actions taken. The Water System shall also document actions taken to improve the efficiency of its municipal irrigation practices. = Special Condition #12 General Reporting Requirements. The Water System shall report the depth of flow over the weir gates at the Bound Brook Control Structure (BBCS) and the Aaron River Reservoir, and flow measurements at four stream gauging stations. TheWater System shall also describe the presence of river herring using the fish ladders. Ms. Leslie O'Shea November 15, 2006 Page 2 Following the meeting, the Cohasset Water System has met to review its current status with respect to the permit requirements of the various special conditions listed above. If additional efforts were determined to be required by the Water System, a proposed action or approach was developed. Please find below an outline of the permit requirements, the current status, and if necessary, the proposed steps to be taken by the Water System. 1. Special Condition #5 Surface Water Protection. The Water System shall submit any existing land use control. Attached please find enclosed the following items regarding the existing land use control measures that have been put in place by the Cohasset Water Dept • XXXXXXXXXXXXXXXX • YYYYYYYYY • ZZZZZZZZZZZZZ 2. Special Condition #7 Seasonal Flow Releases and Drought Management Plan. This section of the permit does not include any reporting requirements regarding flow releases and drought management issues. Other sections of the permit address these reporting requirements. This section indicates the minimal and seasonal reservoir releases from the BBCS and Aaron River Dam. A table in the permit outlines the schedule of releases. This permit requires the Water System to implement the stream flow monitoring plan, as amended in Exhibit "L" of the July 29, 2004 response to DEP and WRC comments. Exhibit "L" requires the operators to conduct the following: a) Weekly inspections of the Fish Ladders, year round. b) More frequent inspections (3 to 5 days per week on weekdays) as Spring and Fall fish-run periods approach. c) Monitor air and water temperatures daily (river herring generally migrate when water temperatures reach 500F). d) At 48°F, operators should increase monitoring the activity of migrating fish at the BBCS. e) As the first river herring are observed at the BBCS, the operator should consult with the Cohasset Conservation Commission to confirm the conditions are in place and the River Herring are present. f) After consultation, the operator will adjust the mode of operation of the weir gate system to allow for sufficient flows (6 CFS in daylight hours) in order to provide attractive flow conditions and to allow the fish to pass. g) The operators will also be in communication with, and request assistance from, other local organizations that are interested and active in monitoring fish runs. This action by Ms. Leslie O'Shea November 15, 2006 Page 3 the operator will occur when the water temperature reaches 480F and observation activities at the BBCS increase. 3. Special Condition #10 Water Conservation/Plumbing/second bullet item. In 2004, an inspection of town buildings listed on the meter reading documents was conducted. Town buildings were equipped with water saving devices (such as low flow toilets or faucet aerators) because the building was either recently built or rehabilitated/retrofitted. The Water System was to submit an account of water saving devices in public buildings as part of the 2005 Annual Statistical Report. A review of the report submitted indicates that the report was not included in the 2005 annual report. Please find attached.. a report summarizing the inspection of town buildings. A retrofit plan and schedule is not proposed because public buildings in the water system have been upgraded to comply with the May 1, 1989 Plumbing Code. The Cohasset Water System continues to support the application of water saving devices in all structures, and will play a role as new public buildings and facilities are built or rehabilitated to support water conservation devices and management. 4. Special Condition #11 Water Use Restrictions. The Water System shall institute water use restrictions indicated in the Drought Management Plan and report all actions taken. A review of the Water System operational records indicates that the department did not require customers to limit the use of water in calendar year 2005 and 2006 (to date). If any efforts are taken in 2006, they will be included in the Annual Statistical Report. The Water System shall also document actions taken to improve the efficiency of its municipal irrigation practices. The Water Department will include, in its 2006 annual report, steps taken to reduce the impact of municipal irrigation systems on the Water System. In 2006, the Water System worked with the Little League Association to convert the supply of water for irrigation purposes from the distribution system to one of the abandoned Sohier Street wells. The Sohier Street Wells (#1 and #2)were included on the systems original registration but dropped as a supply to the Cohasset Water System when the Water Management Act Permit was issued. The wells are located adjacent to the MBTA Greenbush Railroad right-of-way. 5. Special Condition #12 General Reporting Requirements The Water System is required to report various information regarding the two (2) fish ladders/weir gates and four (4) stream gauging stations as part of the Annual Statistical Report. The information to be reported is related to reservoir releases/stream flow and the presence of river herring at the fish ladders. The fish ladders/weir gates are located at the following locations; • Bound Brook Control Structure • Aaron River Reservoir Dam The stream gauging stations are located at the following locations: • Peppermint Brook (#1) • Brass Kettle Brook (#2) • Bound Brook (#4) dmeehan@ci.lexington.t-na.usdmeehan@ci.lexington.ma.us • Aaron River (#5) The Cohasset Water System, with the assistance of a 319 Grant, installed these stream gauging stations in calendar year 2003. These "non-connected" stations are composed of a pressure transducer (to Ms. Leslie O'Shea November 15, 2006 Page 4 measure level) and a datalogger. The stations are generally downloaded on a quarterly basis to retrieve the level information, and the level information is converted to flow, based on the stage:discharge relationship that has been determined for each site. In 2005, the Cohasset Water System upgraded the weir gates and stream gauging stations with automation and telemetry. In the case of Peppermint Brook, Brass Kettle Brook and Bound Brook, the "connected" stations were move close to the street to either gain access to needed electrical power or to locate the station in a culverted section of defined geometry. Due to the location (either close to the Cohasset WTP or remotely located in the woods) and operating costs, radio systems were selected for use to convey data from the weir gates and stream gauging station to the Cohasset WTP. The fish ladders also transmit digital video from security cameras installed at the remote sites. All the remote sites mentioned above use radio as a telemetry system, with the exception of the Aaron River Reservoir weir gate which use Comcast Cable lines. The Cohasset Water System plans to operate the "non-connected" and "connected" stations for a period of about a year of overlapping data. With the overlapping data and periodic flow measurements at the new sites, the stage:discharge relationship can be transferred from "non-connected" to "connected" stations, or developed. Since 2005, the radio system has operated sporadically. The Water System has called in the manufacturer's representatives several times to address the situation. Several steps have been taken including: (1) replacing the majority of the electrical and antennae connections, (2) tightening the connections, (3) changing radio frequencies, (4) raising the repeater antennae on the Bear Hill tank, (5) raising the master antennae at the Cohasset WTP, and (6) verifying signal to noise strength ratios while re-aligning antennas. The Cohasset Water System is presently taking interim steps to convert the stream gauging station and weir gate control system at the Bound Brook Control Structure from a radio connection to a Comcast Cable line connection. This is being done to improve the reliability of the telemetry from the BBCS to the WTP. The radio manufacturer has been instructed to continue to provide a reliable system at the BBCS. The cable line connection will be temporary if the radio system has been found to operate in a reliable manner to transfer information back to the operators at the WTP for reporting. The SCADA system at the Cohasset WTP as related to the operation of the remote weir gates and fish ladders has also been upgraded to record and trend operating parameters. The Cohasset WTP is also undergoing a complete SCADA system upgrade which includes reporting and tabulation software to assist the operators in developing operational reports for various components of the system. The permit requires a submission as part of the Annual Statistical Report to include the following operating data: • Daily depth, water temperature, and release of flow at Aaron River Reservoir Dam • Daily depth, water temperature. and release of flow at Bound Brook Control Structure • Daily and flow measurement at Stream Stations (#1, 2. 4 & 5) • Observations regarding presence and activity of river herring using the fish ladders during the four (4) week Spring (during April to June) and Fall (during September to November) seasons Ms. Leslie O'Shea November 15, 2006 Page 5 Appendix "J" of the March 2004 "Aaron River Reservoir Dam and Bound Brook Control Structure Flow Release and Operational Plan" provided the Cohasset Water System with samples of a log sheet/spreadsheet to record some of the operating data regarding the weir gate for reporting purposes. Since November 2005, the Water Department has not utilized the log sheets to record the operating data. In September 2006, the Water Department began using the log sheets for submission with the Annual Statistical Report, and when necessary, began manually measuring the needed daily data. To provide information when the log sheet was not used, additional sources will be used to supplement the data for submission with the 2006 annual report. Theses sources will likely include those listed below (by parameter): • Daily depth, water temperature, and release of flow at Aaron River Reservoir Dam and BBCS- information will be collected from levels/flows from the "non-connected" and `connected" stream gauge station, the Cohasset WTP daily operations log sheets, daily laboratory log sheets, daily release log sheets, operator records and field notes • Daily and flow measurement at Stream Stations (#1, 2, 4 & 5) - information will be collected from the available "non-connected" and "connected" stations • Observations regarding presence and activity of river herring using the fish ladders during Spring and Fall seasons — information will be collected by the operators records developed and maintained as described above by the requirements of Exhibit "L" The Cohasset Water System has begun the task of summarizing the available information for the above reporting as part of the February 2007 submission of the 2006 Annual Statistical Report. In general, the Cohasset Water System will use the stage:discharge level and flow values from the As stated above the Cohasset Water System is making various changes to improve the operational issues related to releases and stream flows. The proposed changes in the Cohasset Water System includes following the procedures to monitor the activity of river herring (Exhibit "L"), participating in promoting water conservation in new public buildings and facilities that are built or rehabilitated, assessing monthly drought conditions, recording drought action tasks taken, upgrading the operation record keeping (SCADA trending and log sheet entries), Ms. Leslie O'Shea November 15, 2006 Page 6 If you have any questions regarding this matter please do not hesitate to contact the undersigned or Ms. Eileen Commane.

Meeting commenced at 6:55 pm CEDARMERE Mahmood Mahmi and Ginny Messinger of Leggat McCall Properties spoke to the Commission regarding the Cedarmere Project off of Beechwood Street and 3A. The issue is when to pay the fee for instance on a house by house basis or all up front for the project. The concern that Mahmood Mahni has is that the project is currently on hold. One suggestion was to split it not on a house by house or a lump sum paycheck, but a phase by phase basis. Commissioner Pratt asked when they thought that the project will get back under way and Mr. Mahmi stated that this winter he is hoping site work and starting construction in the spring. Glenn explained that whatever the planning board approves that is what we get a system development charge for. There was a lengthy discussion about how the commission wants the main to run and loop up to Castle Road. Mr. Mahmi stated that to include the additional line out to Castle Road, but he will need to take the information back to the Capital Project committee and it will probably take an additional 2 months for a definitive answer. Commissioner McNabb and Commissioner Pratt agreed to let Leggat McCall Properties write up an agreement which states that once the first occupancy permit is pulled then a check would be generated 3300 X 10 X 1.5. Both were in agreement. The agreement will be written up and sent for the Commissions review. GREENSCAPES Julie submitted a report of what happened in 2006 through Greenscapes. Julie has taken over for Wendy Garpow. A proposed scope was left for review for the upcoming year. The flagship of the program is the flyer which is sent to 7000 people on Earth Day. The two bones of contention the program are pesticides and irrigation systems. Last year the 12 communities which are involved gave Greenscapes 100 of the top water users and offered to do a check of their irrigation system. Julie stated that only 10 people out of 1200 responded. They will not do this project again next year. Commissioner McNabb explained how important it is to back the Greenscapes program. First of all it educates the public regarding good practices, but also the Greenscapes people handle all mailings. METER TECHNOLOGY Margaret presented what a fixed network system will do. This allows daily reads, it has a 1 square mile radius. You would need to have antennas throughout the town to be able to read the high and lows of the town. The other option is a Mobil program. This entails a computer in each truck and driving around town getting the readings through a radio read. The commission stated that they were no longer interested in the Mobil program due to the fact that it seems to be outdated. The commission requested that Margaret contact Nathaniel Palmer since he is the commissioner in charge of new technology. The commissioners requested that Margaret contact Keith Moscow of Gammons Road be approached for the architectural part of the intake structure building. DEP Tom Keeffe of Tutela Engineering was present to discuss the draft letter which he wrote to Leslie O'Shea of the DEP S. E. Region regarding issues brought up at the 10/17/06 meeting with the DEP. The Commissioner Pratt and McNabb, Tom Keeffe, Eileen Commane and Steve May reviewed the entire letter Tom Keeffe will make changes and get the letter out by Wednesday November 151n OPERATIONS See attached report by Steve May, Construction Manager, AWS In regards to Brass kettle Brook Glenn wants Tom and Steve to spearhead getting this site fixed. Steve suggested going back to the original person who was in charge of getting the system working. Glenn suggested rip out what is there and put in the new. Glenn also stated he does not want Norfolk Ram involved. That was the end of the discussion Commissioner McNabb then stated he found some over the counter gauges that can be put inside the tank to monitor what is going on in the tank. Tom Keeffe will look into it more, Eileen is concerned because the tank will be back on line in a few weeks. The commission voted on and approved the "Cohasset Water Department Requirements for Construction of Water Lines and Services"—See Attached Eileen requested that the Commission approve Weston & Sampson to look into Chlorine tablets. The cost for the research is $3800. It was approved by the Commission for Eileen to proceed. The next meeting is scheduled for November 21St, Tuesday @ 6:00 pm. Commission McNabb requested that I post this meeting as well as post for the town meeting for both Water and Stormwater Committee. Commissioner Pratt suggested that before the spring town meeting that the commission get together and put something together for the warrant to purchase land and request somewhere around 2million. Commissioner McNabb was in agreement. The commission voted to approve stormwater grant on the warrant. All in favor 2-0.

PRATT, CHAIRMAN DATE: JANUARY 10, 2006 JOHN K. McNABB, JR. - TUTELA ENGINEERING ASSOCIATES, INC. NATHANIEL G. PALMER 12 BAY STREET WILMINGTON_ MA Manganese Treatment Options for Cohasset, MA Background The Cohasset, MA WTP has periodically been faced with consumer complaints due to the presence presence of manganese in the finished water. The manganese_had typically been controlled by the addition of chlorine prior to filtrations. However, due to the very high formation of disinfection byproducts (DBPs), the point of chlorination was moved at after the filters. When this was done, the formation of DBPs was lowered to meet primary standards, but no effective oxidant existed to treat the manganese. During summer 2004, the sand and anthracite media in the filters was replaced with new media; any manganese oxide coating that existed and may have acted as a manganese adsorbent was lost. Following this media replacement, the number of customer complaints increased. In order to deal with the manganese, a procedure was carried out to create a manganese oxide coating on the media. While the procedure was apparently successful, the oxide coating could not be successfully contained. The purpose of this memorandum is to outline the possible fixes to improve manganese removal and to recommend a short-term fix for the problem. Water Quality The raw water in Lily Pond is typical of many shallow New England ponds. The water has high levels of organics (average of 9.8 mg/L with a maximum of 17 mg/L), has a low alkalinity, and moderate to high levels of manganese (average of 0.09 mg/L with a maximum of 2.00 mg/L). This combination of high organic matter and low alkalinity results in a water that is very difficult to treat by conventional coagulation. Treatment Plant Description Raw water from the Lily Pond flows through a 24-inch gravity raw water main into a wet well. Potassium permanganate andand lime are fed into the raw water well at the entrance to wet well. Raw water is pumped out of the wet well by three raw water pumps into two rapid mix tanks. Ferric Chloride is fed into the raw water pump discharge line before the rapid mix tanks, where polyaluminum chloride and polymer are fed. There is also the ability to feed chlorine into the rapid mix tanks; however, at this time, it is not being used do to its drastic effect on disinfection by-products. Water flows from the rapid mix tanks into two flocculation tanks. The flocculated water is collected in the settling tank influent channel, which has stop gates to direct the flow into one or both settling tanks. Flocculated water flows through the settling tanks to settle the sludge. The settling tanks are equipped with inclined tubes to assist in clarification. A sludge rake collects settled sludge in each of the settling tanks and the sludge flows by gravity to the two sludge and waste water lagoons. Settled water is collected in a common filter influent header water flows into one of three box filters. Each of the three filters contains 34 inches of dual media, 16.5 inches of anthracite and 17.5 inches of sand and a rotating surface wash system. Filter effluent is collected in a common header which flows into the clearwell. Chlorine is added to the combined filter effluent just before the clearwell.Two pumps are used to backwash the filters with the backwash waste flowing into a waste water sump, where two pumps will send the waste water to the two sludge and waste water lagoons. There are not any provisions for filter- to-waste or air wash although installation is scheduled for next year.. Three high service pumps deliver water to the distribution system from the 150,000- _ _ gallon clearwell. Fluoride, lime, and chlorine are added after the high service pumps into the 14-inch high service distribution main. At present, permanganate is being fed into the raw water at a dose of 3.5 mg/L. Because the coagulants are fed shortly after the permanganate there is not enough contact time for effective oxidation of the manganese. While it is likely that some of the manganese is oxidized, these particles are probably colloidal in nature and not effectively coagulated and filtered. Pilot Testing Pilot testing has been conducted in order to upgrade the treatment plant; option for upgrades include MIEX ion exchange resin, intermediate ozonation with GAC media in the existing filter beds, or post-filtration ozonation with new GAC contactors. The testing has shown that these options will significantly reduce the formation of DBPs as well as remove manganese. Because the long-term solution for the disinfection by-product issue that will be designed and built will also effectively treat manganese (based on pilot testing), a shorter term, low capital option is desired to improve removal of manganese and reduce customer complaints. Treatment Options General Manganese is typically removed from water by either precipitating it using strong oxidants with subsequent particle removal (clarification and filtration) or by a catalytic reaction on manganese dioxide-coated filter media (typically filter media or greensand zeolite). Oxidation/precipitation can be carried out at any location upstream of the filters. Catalytic reactions are carried out in the filters themselves. Detailed discussion of these removal methods follows. Oxidation/Precipitation Dissolved manganese typically exists in nature in the reduced +2 oxidation or manganous state. Under anoxic conditions, such as in lake sediments or in stratified water columns, the +2 state is stable. In this form, manganese does not complex strongly with organic matter, unlike dissolved iron. However, when an oxidant is introduced, the manganese can be converted to the +4 oxidation state. In these oxidized states, the metal will tend to precipitate, first as colloids, and then agglomerate into settleable solids. If sufficient dissolved oxygen is present, the solids tend to be MnO2, but other solid forms exist, including chloride and sulfate salts. For—manganese,—another oxidation state exists;-the +7 or—permanganate—ion.—In—this state, the manganese is again in the dissolved form. Very strong oxidants such as ozone can "over oxidize" precipitated manganese and re-dissolve the manganese. In the dissolved +2 oxidation state, some manganese can be removed by coagulation. However, most will pass through the treatment process. If chlorine is used for primary or residual disinfection, the metals will precipitate and deposit, leading to consumer complaints. This illustrates the importance of proper oxidation and removal by clarification or filtration. The logical places where an oxidant for effective oxidation could be located in a water treatment plant are at the raw water source,after flocculation (prior to clarification),_and__ prior to filtration. Four oxidants are commonly available to oxidize manganese: chlorine (in the form of gaseous chlorine or sodium hypochlorite), chlorine dioxide, potassium or sodium permanganate, and ozone. Unlike iron, oxygen (in the form of aeration) is not an effective oxidant for manganese. Does this mean that the planned aeration of the pond will not provide manganese reduction? The planned aeration in the pond will be an attempt to add oxygen to the pond water, keeping manganese deposits in the soil and preventing them from rising into the water column. This aeration will not precipitate the manganese like a normal oxidizer would in the plant due to the fact that they pond pH is too low. To effectively oxidize the manganese in the water, some dedicated contact time will be needed. Typically, the oxidation of manganese to settleable solids is slow (on the order of minutes to hours) for the four oxidants mentioned above in the pH range experienced for many raw waters. Because of the nature of the pond, a significant additional oxidant demand due to organic matter exists. In order to effectively treat manganese, two distinct steps are required — the first to oxidize the dissolved metal into a particulate form and a second step to remove the particulates. The first step requires chemical feed(s) and a contact basin to provide reaction time. The second step may, depending on the oxidant used, require coagulant addition and clarification. The ultimate particle removal is accomplished by filtration using conventional gravity filters, pressure filters, or low pressure membranes. Because Cohasset already has clarification and filtration in place, these would be used to remove that particulate manganese. Therefore, only the addition of an oxidant will. be required. The following lists details options for oxidation of manganese. Oxidation •Chlorine Chlorine is capable of oxidizing manganese; however, the reaction tends to be slow, except at elevated pH. Under acidic or near neutral conditions, it is common to use large contactors. According to Susumu Kawamura's book "Integrated Design of Water Treatment Facilities", at pH 8.5, manganese oxidation by chlorine will take 2-3 hr. The stoichiometry for manganese oxidation is approximately 1.3 mg C12/ mg Mn2' excluding the chlorine demand due to the organic matter in the water. Because of the high level of disinfection byproduct formation, even prior to filtration, chlorination is not a viable alternative for Cohasset. It would be possible to oxidize the manganese with chlorine prior to filtration and then create chloramines in the clearwell to prevent high levels of disinfection by-products forming. However, a chloramine conversion takes significant planning and notification for the community. Additionally, because of the interconnection with Hingham (which uses free chlorine), the use of chloramines as a secondary disinfectant is not a viable option. • Permanganate _ ___Using permanganate is another_ effective oxidant to-remove manganese. The oxidation_ of dissolved manganese by permanganate is rapid across a wide range of pH. However, if an overdose occurs, excess permanganate can pass through clarifiers and filters into the finished water and produce a characteristic pink color, leading to consumer complaints. Typically, because of the possible creation of pink water in an overdose situation, permanganate addition in the plant is usually not pursued for direct oxidation and precipitation unless no other options exist. According to stoichiometry, a dose of 1.92 mg KMnO4/mg Mn2+ is required (1.72 for liquid sodium permanganate). However, because of the high levels of organics, the actual permanganate dose will like be significantly higher than the stoichiometric dose. . Chlorine Dioxide Chlorine dioxide is a much stronger and more specific oxidant for iron and manganese than chlorine. Because it is unstable, it can only be generated on-site. There are two primary generation methods - one based on sodium hypochlorite, and the other based on chlorine gas. Current standards limit the maximum chlorine dioxide residual concentration to 0.8 mg/I and the MCL for chlorite (the by-product of chlorine dioxide reactions) to 1.0 mg/I. The advantage of the gas-based generation is that no chlorite is present in the feed solution (chlorite is often a contaminant in the hypochlorite-based generation systems formed by the degradation of the hypochlorite). The use of chlorine dioxide will speed up oxidation compared to chlorination - above pH 7, the stoichiometry is 1.2 mg C1O2/mg Fe and 2.4 mg C1O2/mg Mn. This reaction will take place in 5-10 minutes. Because of the high levels of manganese in the water, the dose requirements for chlorine dioxide would result in chlorite levels greater than the MCL. Because no chlorite removal mechanisms (such as GAC filters) currently exist in the plant, chlorine dioxide is not a viable option for Cohasset. •Ozone Ozone is the strongest oxidant typically used in water treatment. Ozone readily oxidizes dissolved manganese. The kinetics of manganese oxidation by ozone are rapid under most pH conditions. According to the stoichiometry, a dose of 0.87 mg 03/mg Mn2+ is required. Possible drawbacks to using ozone for iron and manganese oxidation are the high capital and O&M costs, system complexity, and regulatory impacts. In normal operation, - - ozone-will oxidize-the dissolved-manganousion (Mn 2+), to-insoluble MnO2. If excessive — ozone is added, the insoluble MnO2 can further be oxidized to the soluble permanganate ion (MnO4-) causing pink water. Ozonation is one of the options that has been piloted for Cohasset. Due to the equipment required to generate ozone, it is not a short-term solution for the manganese issues. Catalytic Removal When manganese dioxide deposits as a coating, it can act as a catalyst for further oxidation of reduced manganese. This process works in much the same way as _ _greensand zeolites. When used in filters,_the oxide-coated media- is _a_ very efficient _ method for removing reduced metals. As long as an active oxide coating exists, this autocatalytic oxidation will take place and more oxide coating will build up. The method is effective when limited contact time exists for conventional oxidation and precipitation. The mechanism occurs when dissolved manganese is adsorbed to the surface of the oxide coating the media grains. Previously precipitated manganese then oxidizes the dissolved metal to the solid form. Because an adsorption/surface mechanism is occurring, the process is optimized by increasing the surface area for adsorption. This is best done by using small filter media grains. Therefore, it is most often seen in sand filters, although the mechanisms also will take place on anthracite grains and possibly membrane surfaces. Because the manganese dioxide coating is black, however, the coating is more easily observed on sand than on anthracite. The oxide coating can be created in several ways. If an oxidant is continuously added to water containing manganese, over a long period of time, a coating will deposit naturally. Many treatment plants have oxide-coated media and may be unaware of its presence. A second method of creating the oxide coating is to "seed" the filter media with a percentage of media that has already been coated. This seed will begin the autocatalytic process and the oxide coating will expand to uncoated media grains. The most common way of creating an oxide coating by allowing the filter media to soak in a high concentration of potassium permanganate (typically up to 100 mg/I for 12-24 hours under proper pH conditions). The permanganate will precipitate on the media grains as manganese dioxide and the coating will be created. As with greensand filters, an active oxide coating must be maintained using an oxidant. This maintenance can be done either with a continuous feed or intermittent regeneration. If a continuous feed is used, an oxidant residual should be carried through the filter. The residual required is site specific, but can range up to 1 mg/I for free chlorine. Previous testing with intermittent regeneration indicated that this method did not work at Cohasset. Therefore a continuous oxidant feed will be required. As with conventional filtration, when the headloss across the bed becomes too great, the filter is backwashed to remove solids prior to returning it to service. Summary Because of the high concentration of organics and manganese in the water, the choice of oxidant is limited to permanganate unless significant changes are made for the inclusion of a removal mechanism for chlorite or an agreement can be reached with Hingham to allow the use of chloramines. Because the treatment plant will be upgraded with fixes for the DBP and manganese issues in the long-term, a short-term, low capital cost option is desired to treat manganese without causing an increase in disinfection by-product formation. The only oxidant that might be logically used is permanganate. Based on the stoichiometry of sodium permanganate and manganese, a dose of in excess of 2.1 mg/L can be expected based on a maximum raw water manganese of 1.2 mg/L. For planning purposes, in order to meet the oxidant demand of the raw water, a dose of 2.5 mg/L might be anticipated. The dose will need to be confirmed by bench testing. I would anticipate a much higher permanganate dose then predicted due to the _ massive amounts of organic material that will be oxidized. We currently feeding 3.5 ppm of Kmn04 and do not even have the slightest hint of pink water right at the injection point. Permanganate could be added in several places in the plant. As previously mentioned, permanganate is added at the beginning of the raw well. Due to a lack of mixing and very little detention time before the concurrent addition of coagulant, the chemical appears to be ineffective at this point (or dose). In order to increase its effectiveness, .(It is already there, Alternatively, the permanganate feed could be moved further downstream and added to the filter influent header. The filter influent header would only allow for a minute or two of detention time before contacting the media depending on the filter flowrate Dosing Control If the permanganate is added to the raw water (either at the intakes or into the wet well), the dose would be determined based on the raw water manganese and demand due to organics in the raw water. Dosing will be controlled based on finished water manganese. Because no standard method exists for measurement of permanganate ion separate from manganese, in order to determine if finished water manganese is in the permanganate (dissolved) form or particulate form, the use of both typical manganese testing (via a Hach or similar test kit) and Oxidation Reduction Potential (ORP) probe will be required. Finished water samples should be monitored for total manganese and ORP every shift until a better operational history is developed. During periods of rapidly changing water quality, more frequent manganese measurements may be required. If the permanganate was added to the settled water, the dose would be determined by the settled water manganese and organic demand. The dose could be controlled either using an ORP probe or amperometric titration to determine the oxidant residual above the filters. Because some continuous oxidant will be necessary to maintain an oxide coating on the media, a small amount of permanganate is desirable; however, too much will result in pink water and subsequent customer complaints. Because of this, a delicate balance is required. Therefore it is suggested that a permanganate residual of no more than 0.2 mg/L as Mn04 be allowed in the filter influent. Additionally, manganese levels above and below the filters should be monitored every shift until a better operational history is developed. During periods of rapidly changing water quality, more frequent manganese measurements may be required.
