The motion carried by a vote of 3 to 0 with three commissioners abstaining (Yingling, Schreiner and Johannessen). V. UNFINISHED BUSINESS a. Wetland Ordinance Planner Flnwali gave a brief summary of the public testimony from tria last meeting. Discussioll on Mobile Nome Park Issue: Chair Yingling wondered if there should be some reference in the wetland ordinance regarding Minnesota statute discussed by Planner Finwall which would allow manufactured homes to be rebuilt with their existing setbacks. 2 Discussion on Nonconforming Single Family Homes.' Chair Yingling asked what is done about a home that is destroyed such as by fire or a natural disaster when it is a nonconforming property. If the plan is to rebuild on the existing foundation how does that apply the wetland ordinance? Is it prohibited because it is nonconforming structure or is there and exemption? Planner Finwall responded that if an ordinance is adopted and the structure becomes nonconforming and is destroyed to more than 50 percent of its fair market value then it could not be rebuilt without a variance. Planner Finwall commented that if homes within wetland buffers are damaged by a natural disaster and the property owner wants to rebuild, then the city would have the opportunity to review the request and make improvements such as increasing or improving the buffer through the variance process. She asked if it commission wanted to review language that would allow those homes to be rebuilt without a variance if the met a minimum setback and if improvements were made to the buffer? Commissioner Trippler stated that the variance process would allow the city controls over the new house's location and conditions to improve on tl;I,e buffer. '" Commissioner Schreiner commented that from~{:hghn, owner's perspective he would like to see some kind of language that would protect thE'l,fibrneo ."

Ome kind of language such as if the home is totally destroyed that nothing gets an'y:..i::loser to the buffer than the existing foundation was.

" H,'"\,,., it' Chair Yingling sugg~'~t~2Iang, go' that would provide people with some level of comfort regarding what they can. it\f,puil,d on their property. Commissioner Trippler cOn1mented that we need to put together a wetland ordinance that protects the wetlands and if there is a disaster that people will be reasonable enough to work out a compromise so that everyone is satisfied. Council member Kathleen Juenemann approached the podium and suggested standards for allowing rebuilding of homos within the buffer' Sharcn Sandeen, resident at 1748 Guidon Place, approached the podium and made some suggestions and comments: . The more restriction you impose by an ordinance the more issues YOLl have affecting property owners. . For some property owners existing buffers are being tripled. . The whole width of buffer zones is an impOliant component to this because if the recommended widths aren't adopted then the result will be the tripling and doubling of buffers. . You have to consider the existing setback requirements for homes. . If the city's current buffer widths currently exceed the states guidelines what is the rational and the basis for going beyond that? ., .' Chair Yingling stated that she would like to see language which would allow homeowners to rebuild as long as they were a minimum of 50 feet to the wetland. Commissioner Trlppler would like a clear distinction made between setback and buffer requirements on a lake versus a wetland. A setback to the lake as required in the shoreland ordinance refers to how far a structure can be built from the lake and offers protection to the water quality of the lake. Buffers are areas which cannot be mowed or cut in addition to areas where structures cannot be built. They are intended to protect water quality and to provide some passage way, living space, etc., for wildlife. That is why our proposed wetland buffers exceed the shoreland setbacks. If a property is within the 50 foot setback and It gets destroyed it is up to the ruling body whether a variance is issued. He would not like to see language in the ordinance which would allow those properties to be rebuilt. Chair Yingling suggested that there be a minimum setback of 50 feet to be able to rebuild without a variance. Chairperson Trippler asked what happens if they are in an area that has a 100-foot buffer? He feels if they are in a setback or buffer then they should be required to come in for a variance. Chair Yingling made a motion to put in language to homeowners some assurances. Commissioner Mason Sherrill suggested that wetland working with the city for the same g be an opportunity to enhance the Commissioner Trippler will second the motio develop best management practices tgjmprov ,:".:!:,::,::" ,: ";;"/Hy . 'it'lncludes staff working with homeowners to the buffer. l:'".,J Commissioner Schreiner stated that the language should cover destruction of homes by natural disaster only, so that we are not creating a loophole for someone to destroy their home by tearing it down just to rebuild. The motion carried by a vote of 5 to 0 with Commissioner Johannessen abstaining. Staff will draft language and bring it back for the commission's review. Discussioll on Issues Raised by l'?esident Bruce Olsen in his May 7, 2008, Memorandum: Chair Yingling suggested taking a look at sOllie of the r-ecommendatlons that were submitted by Bruce Olsen. Cllalr Yingling suggested adopting the chan<;jes in language as follows. 1. Page 2, second paragraph, Item three. 2. Change in language as suggested on page 3, item 7. 3. Change in language as suggested in Item 8. 4. Change in language as suggested in Item 9. 5. Change in language as suggested in Item 10. 4 6 Items 12 and 14. 7. Item 20 Chair Yingling made a motion to adopt the changes as specified, seconded by Commissioner Trippler. The motion passed by a vote of 5 to 0 with Commissioner Johannessen abstaining. Commissioner Yingling suggested that the commission take a look at the memo from Sharon Sandeen. She also proposed that time is set aside to have a workshop. She reviewed the issues that were brought up in the memo. She feels it is worth looking at exemptions of what people can do within their existing mowed lawn. What practical things we can suggest for exemptions for activities on properties that are already developed. Commissioner Trippler stated that the purpose of having the buffer is to provide wildlife for an area to move from one wetland to another and to create habitat. He feels that common sense would dictate what a homeowner can do within the buffer as long as it allows wildlife the freedom to move about. He is hoping that staff can come up with suggestions. Planner Finwall stated that maybe there needs to be some clarification regarding what a homeowner can do with their mowed yard that is in a buffer versus what is allowed within a naturalized buffer. gives people clarification that there Chair Yingling feels there needs to be some are activities in that maintained lawn area. n',,_'1 Naturalist Gaynor stated that we are talking~bquipeople who are grandfathered in with their lawn. We need to be clear about lawq;> that a~l!\',gr9ndfathered in. \:""" -".-",1;:< Commissioner Trippler would li~yto se&'th~2itystaff work with property owners who have mowed lawns within a wetla dHUfI'er abdyt installing a rain garden. ':~~~tOr;;mission needs a definition of what is meant by yard Naturalist Gaynor asked activities. , "i-"f' "'i"'" ''''0' ,"" .'. ,',' f'i.. ;.:< Chair Yingling commentad.,thal\ve need to differentiate between the lawn areas versus, naturalized areas, versus ri'l)tive areas. Ginny Gaynor stated that what she is hearing is that gardens and temporary structures should be okay in an existing lawn area that is grandfathered in. But a patio with a foundation would not be okay in a buffer. Would a bench, fire pit, or compost pile be okay in the buffer? Commissioner Lynne thinks that portable objects are Fine but not something permanent on the propel1y. Commissioner' Schreiner is concerned wilh sheds in the buffer. Commissioners directed staff to come up with language for specific items and to sclleclule a wetland workshop in August to complete the review. b, Comprehensive Plan" Suslainabl!ity Chapter Commissioner Mason Sherrill wanted to add two points. Under tree issue, goals, number 5, adopt urban tree program, down under implementation strategies there is nothing mentioned on trees. She wants to add something under the education, partnership, implementation and strategies "to establish and maintain our urban tree program" we need to implement the USDA ) forest research service program and tools. Under polices ordinances and programs she would like to see a point stating that we will enforce our current tree ordinance, she doesn't feel it is being enforced well. Commissioner Schreiner suggested under goals item 4, he would like to see the word encourage be replaced with the word require. Commissioner Schreiner under education partnerships, he wants to change the wording to "coordinate with mass transit providers." Commissioner Schreiner would like to see one item added; a requirement that any and all new developments provide access to available mass transit. Commissioner Lynne under page three on the top the wording is not strong enough. It does not mention how you would have efficient trash hauling. IX. STAFF PRESENTATIONS Planner Finwall mentioned the following:- o National Night Out is August 5. o Alternate dates for the next Commission meeting. o Recycling bin distribution by Eureka during o Maplewood nature center programs - which is scheduled for August 23.

ENVIRONMENTAL AND NATURAL RESOURCES COMMISSION MINUTES TUESDAY, JUNE 24, 2008 COUNCIL CHAMBERS .- MAPLEWOOD CITY HALL 1830 COUNTY ROAD BEAST I. CALL TO ORDER Chairperson Yingling called the meeting to order at 5:15 p.m. II.

APPROVAL OF AGENDA Commissioner Musgrave would like to discuss what Depot is doing with recycling of CFL bulbs. Commissioner Trippler made a request to presentations a suggestion on Tyvek envelopes. Commissioner Trippler made a mo agenda as amended, seconded by Carol Mason Sherrill. The motion carried IV. APPROVAL OF a. May 20, 2008 Commissioner Musgrave stated that she has several issues to discuss concerning the minutes. Commissioner Trippler made a motion to table the minutes in order to review Commissioner Musgrave's comments during the next meeting, seconded by Commissioner Mason Sherrill. The motion passed by a vote of 6 to O. UNFINISHED BUSiNESS a. Wetland Ordinance Planner Finwali discllssed the staff report and discussed several issues to include: 1. If a yard is maintained as turf grass adjacent to a wetland and the ordinance Is adopted wltl, increased buffers can a resident still maintain this area as turf grass? Also, what other activities can take place within this area of the buffer? There is a need to clarify temporary and permanent structures in the definitions as well as added uses. 2. The edges of Wakefield Lake are currently classified as a Class 4. The watershed districts new classification would upgrade the wetland to a Manage B. The proposed wetland c, L ordinance would require a 75 foot buffer from a Manage B wetland Wakefield Lake is also located within the shoreland overlay district. Sc there Is also a 50-foot building setback from the ordinary high water mark of Wakefield Lake within this district. 3. The City of Maplewood had four manufactured homes that are adjacent wetland buffers. The way the current wetland ordinance is written, the removal and replacement of one of these manufactured homes within a required buffer would require a variance. COMMENTS AND CONCERNS FROM MEMBERS OF THE PUBLIC REGARDING THE ORDINANCE: 1. Sharon Sandeen, 1748 Gulden Place, Maplewood: Her main concern relates to Ms. Sandeen's opinion that Maplewood as a city does not have the authority to regulate the edges of Wakefield Lake as wetland when the lake is defined as a public water. Also, Ms. Sandeen recommends that the ENR commission review language in the ordinance to ensure less ambiguity and allow for more active uses within buffer zones. 2. Steve Bryan, 1752 Gulden Place, Maplewood: He has concerns with water quality and current management practices of Wakefield Lake. 3. Linda Bryan, 1752 Gulden Place, Maplewood: She has concerns with water quality and current management practices of Wakefield Lake. 4. Tom Devnick, Attorney representing Gary PearsqQ, manager of the Beaver Lake Manufactured Home Park: Proposed langua~\7'!,~ the nonconforming portion of the wetland ordinance to allow manufactured homes to.Q\7 reiili}Slved and replaced if located within a buffer without a variance (Attachment 6),.' ,:" . 5.

Cope Avenue - Vacant Property Owner: Concerns with upgraded classification of wetland on his vacant property and a 75-foot buffer which may cause the property to be unbuildable. COMMISSIONEF? COMMENTS REGARDING PUBLIC INPUT The commissioners thanked the public for tlleir input. Planner Finwall ccmmented tbat many of these concerns can be addressed at the July '15 meeting. Chair Yingling commented that this ordinance will continue to be revised with improvements in language. Slle also mentioned that tbe goal is to find a balanced approach. stated that the Commission appreciates the input the public provided Chair Yingling made a motion to table further wetland ordinance discussion to the July '15 meeting, Carol Mason Sherrill seconded. The motion carried by a vote of 5-1, with Commission Trippler voting against the motion. 'l b. Comprehensive Plan ~ Sustainability Chapter Planner Finwall asked for Commissioner comments on the draft plan: Commissioner Trippler had a question on page 3, 5th bullet down - why is "boulevard" crossed out from the tree goal? Commissioner Mason Sherrill commented that boulevards are not the best place to plant trees so the goal should just specified trees, not boulevard trees. She feels the sentence stating "new subdivisions are required to plant boulevard trees" should have been revised to also say just "trees.ll Commissioner Trippler is wondering what does "development review" mean in next bullet down? Planner Finwall responded that it is referring to the review of developments through the land use review process. We could clarify the language by stating 'land use permits." Commissioner Musgrave is concerned that regarding the development reviews the city uses consultants to review these. She said it seems like a loophole for approvals to spend money. ,<h Naturalist Gaynor briefly reviewed the land use d\l~~lopment process saying that when these applications are submitted staff reviews them ~Il? bri~,~s them through the process. There are some occasion were a consultant is hired to)dbk at th~:Rlan but in general staff, Commissioners, and the City Council revi",. 1 .', . ~pdorse the use of alternative modes of .~i than through the development review Commissioner Musgrave suggested transportation when reviewing develo process. Chair Yingling suggested th~irL process to actively prol1)qt'?Jhe' g~,a~e' should read "use the existing development review ('alternative modes of transportation." ',;;' . 'it':' :; ''iii,!';, Planner Finwall will ~Iso add pefle rian as a mode of transportation. Commissioner Musgrave cqtTimented that she does not see a reference to trails. Chair Yingling suggested on item number 6, page 2 under goals, she feels we should not be providing transportation just for citizens without cars but instead it should just state provide transportation "for citizens by promoting and integrated transportation system that is accessibie, safe efficient... etc." This language will promote the reduction of air pollution and connection of pedestrian and bike trails. Commissioner Musgrave recommended that the word citizens be changed to public. Commissioner Lynne referred to a concern regard'ng garbage collection; the damage from multiple haulers is 8S heavy as the buses that are on White Bear Avenue. Where should this be addressed? Naturalist Gaynor responded that people have a strong feeling about being able 10 choose their own trash haulers. It could be in the chapter as encouraging practices thatllelp reduce pollution in our neighborhoods and wear on our roads. 4 Commissionsr Musgrave commented on f, a statement couid be added such as "promote low- impact environmentally sensitive practices by business and residents or the public." This could be done through education and survey of public. Planner Finwall stated the intent of the goal is to ensure there are not so many trash hauling trucks traveling down the same road which pollutes the air and puts wear on the roads. Commissioner Musgrave commented that she doesn't see any reference to agriculture, people growing their own crops, or encouraging smaller businesses. She stated that at one time there was discussion regarding setting aside land in Maplewood for people to do their own farming. Naturalist Gaynor responded that the city has looked into having a community garden and finding an area that works. This issue is addressed in the overall comprehensive plan. Commissioner Mason-Sherrill would like to see something on education and encouragement of homeowners that states we need space to rent for vegetable gardening. Commissioner Musgrave would like to encourage sustainable farming and community gardens. Chair Yingling commented on sustainability. We arEi,missing the notion of studying and developing reports or proposals to the city and coming up with priorities for things that need to be done. Is there more of a comprehensive approa6P"Jo look at the kinds of opportunities and developing programs like St. Paul has done,16''become'ill,sustainable city? She recommended that someone work with staff to look for oppi;lrturlities for '.(::ommunity gardens. <''<'" ,';'"--''' Planner Finwall commented that in thi'~i'9~aPtefib,Qi?lOr education there is an annual report to the city council where the commission can.ifilid,ijip opportunity to report on areas of need.

Perhaps the gardens could fall under this area. AlsQican theli\51 bullets be placed in chronological order or placed according to v~u~ ." " , ", ;,;,_, d Commissioner Musgrave'~ug~ested the need to put something about identifying visions. Chair Yingling mentioned that a goal is to promote local production and consumption of locally produced goods and produce. We want the communities to become more self sustaining. Commissioner Musgrave suggested that there could be somethin,J here on addressing health issues by using the parks. Commissioner Mason Sherrill suggested that under education and partnerships she would like to add "city cOllncil and community." Also regarding the tree section" where it says to create ordinances, we shouid change "create tc update." There is nothing in there about Tree City USA; she is concerned that we are not fulfilling the requirements of this. Naturalist objectives. said that if we Ilave strong goals then maybe our work becomes Commissioner Mason Sherrill is concerned about E.merald Ash Barer and stated that we need to be proactive. 5 Cllair Yingling suggesled that under educaton and partnerships there is something on encouraging individual and residential cemposting. Chair Yingling had a question on page four, the second bullet; she wondered why we went from using bio diesel to alternative fuels. Planner Finwall responded that there were concerns about the energy needed to create bio- diesel fuel. Chair Yingling stated that her concern was opening it up to alternative fuels which people could interpret as ethanol. She would like it to read something like environmentally sustainable alternative fuels. She would also like to add that we encourage transit bike and walking for employees. Metro Transit does a nice job of working with employees. Commissioner Musgrave has the following concerns: 1. Page 2, educational partnerships. She is wondering if it is necessary to create so many newsletters and brochures and asked if there is a way to keep the cost down. 2. The section "Work with Other Government Upi!s" only refers to noise and doesn't mention pollution. She would like to see cl}nention of air and water pollution along with noise pollution. . ,';:U,.,\ '\:::;,:!,., 3. Page 4 City budget - she feels the cbrten!.is too general.

The motion carried by a vote of 5 to 1 with Commissioner Musgrave voting against the motion 8~cause she would prefer having staff make the suggested changes and then bring it back before the commission once again for approval. Viii. COMMISSION PRESENTATIONS a. Commissioner Musgrave commented on CFI. bulb recycling: She read an article regarding compact florescent light bulbs which indicated that Home Depot is starting free recycling for these light bulbs. b Commissioner Trippler commented on recycling Tyvek envelopes: I-Ie stated that for years the pollut;on control agency has been recycling tlleir Tyvek envelopes. Tyvek is a practically indestructible material, and he it seems wasteful that we are getting our material In these envelopes and throwing them away. We could recommend 2nd encourage city cOllncil and all the other committees to save their envelopes and leave them here before the commissioners leave and the envelopes could go back to the secretaries to be reused. 6 IX. STAFF PRESENTATIONS a. Planner Finwall commented on New Member Orientation and welcomed Bill Schreiner b.

MEMORANDUM TO: Environmental and Natural Resources Commission FROM: Shann Finwall, AICP, Environmental Planner SUBJECT: St. Paul Regional Water Services - Zebra Mussel and Other Invasive Species Management Plan DATE: August 14, 2008 for the August 19 ENR Meeting BACKGROUND The St. Paul Regional Water Services (SPRWS) provides water service to the majority of Maplewood's residential and commercial properties. The SPRWS McCarrons Water Treatment Plant, located at 1900 Rice Street in Maplewood, is supplied with water which is pumped from the Mississippi River by the Fridley Pump Station and discharged to the Vadnais Chain of Lakes in Shoreview. Zebra mussels have spread throughout the Great Lakes into the Mississippi River and its tributaries. Zebra mussel infestation can cause a range of environmental impacts that affect biological organisms and have also been known to cause hydraulic problems on infrastructure such as plant intake pipes, screens, and pump stations. The presence of zebra mussels in the Mississippi River and the recent discovery of adult mussels in Vadnais, Sucker and Pleasant Lakes prompted SPRWS to evaluate the infestation potential, subsequent impacts of zebra mussels on the watershed and supply system, and zebra mussel management strategies (refer to executive summary of the management plan - Attachment 1). DISCUSSION Potential Spread of Zebra Mussels One of the objectives of the plan is to minimize the potential spread of zebra mussels and other exotic species to other water bodies as a direct result of SPRWS actions. Control points represent the locations within the SPRWS system that are potential points of entrance or spread for zebra mussels and other invasive species. The Vadnais conduit drain control point allows water to drain from the conduits and flow through natural drainagways to I_ake Gervais or Trout Brook. It is used periodically for inspection and maintenance. The management plan states that zebra Il1lissel spread in this location must be prevented eluring the periodic draining of the facilities. Tile pian offers solutions to this problem including operational (pumping water to the other conduit rather than to the lake), filtration (draining water through a filtration bag that would trap adult and veiigor state mussols), or chemical additions (portable ozone facilities used to disinfect the water drained). Each solution offers varying degrees of success and expense as specified in the estimated costs assessment (Attachment 2). Department of Natural Resources Review The Department of Natural Resources (DNR) reviewed the management plan and submitted a letter of concern to SPRWS (Attachment 3). The DNR found that the plan did not identify ideal solutions for addressing the issue and encouraged SPRWS to continue to look for long-term solutions through planning and evaluation of new technologies. Impacts to Maplewood Zebra mussels can have a large environmental impact on Maplewood's water bodies by fouling beaches with their shells, interfering with the existing food web, smothering native mussels, and they have also been connected to other fish and wildlife die offs. Management of zebra mussels would also cause an economic impact on the city. As such, the City of Maplewood has a vested interest in ensuring that SPRWS' operations do not cause the spread of zebra mussels or other invasive species into our water bodies. Board of Water Commissioners The SPRWS is governed by the Board of Water Commissioners, which consists of three members of the Saint Paul City Council, two Saint Paul citizens, and two representatives for the suburbs served by SPRWS. The Board will review and discuss the management plan and finalize recommendations during their September 9, 2008, meeting. RECOMMENDA liON The Environmental and Natural Resources Commission recommends that the St. Paul Regional Water Services work with the Department of Natural Resources on long-term solutions to the spread of invasive species through water operations. Until an ideal solution is created that will ensure no spread of invasive species by water operations, the Environmental and Natural Resources Commission makes a strong recommendation to the city council and the St. Paul Regional Water Services that the draining of water which may contain zebra mussels or other invasive species from SPRWS conduits into drainage ways which will enter Maplewood's Lakes and streams is unacceptable.

Since then they have spread throughout tile Great Lakes and into the Mississippi River and its tributaries. TI1e continuous flow of water and nu trients in water intakes, pump stations, and water transmission lines provide favorable breeding grounds for mussels. The mussel's high reproductive rate and ability to firmly attach to hard surfaces can result in significant reduction of hydraulic capacity. Mechanical equipment may also be damaged or rendered inoperable if obstructed by large quantities of mussel shells. In addition, taste and odor problems may occur when the mussels die or when dead mussels accumulate in treatment process areas. The presence of zebra mussels in the Mississippi River and recent discovery of adult mussels in Vadnais, Sucker and Pleasant Lakes prompted Saint Paul Regional Water Services (SPRWS) to evaluate the infestation potential, subsequent impacts of zebra mussels on their watershed and supply system, and zebra mussel management strategies. In addition to zebra mussels, the management plan was expanded to address transfer of other invasive species into or out of the SPRWS reservoir system. Objectives The three primary objectives that SPRWS developed for this Plan are: Objective 1: Effectively manage SPRWS infrastructure to minimize operational impacts caused by zebra mussels. This objective involves actively monitoring existing facilities for the presence of zebra mussels and then implementing necessary measures to keep the facility operating efficiently if and when it becomes apparent that the mussels are likely to cause operational problems. Objective 2: Minimize the potential spread of zebra mussels and other exotic species to other water bodies as a direct result of SPRWS actions. This objective involves minimizing the opportunity for zebra mussels and other exotic species alread~y present in the SPI-<_VV5 reservoir systern to illigrate to adjacent \vater bodies as H direct rt-;sult of SPR\-'VS actions, ho\,vevpJ', transfer of zebra rnussds or other exotic species frcnn the SPF.VVS reservoir cannot bi::: conh'olled by SPl\\NS alone., Tn\rasi.vp species could be trm1.sferred ouL of 1:1.1.2 SPRVVS resen/olr s.ystprn by the general p-ubhc tllfOUgh activities such as boating or fishing, Objective 3: the potential SPRWS w of other as a SPRWS adions, Sirrti.lar to Objecti'/f: 2, this ubjecb\re also requires the ,.dentiJication of any Clurel1t SPRvVS operations and 111a1.ntcnan.ce activities that cou ld facilitate the inh'oductiOl1 of exotic species not currently in the SPRWS water bodies. Feasible means of altering ES-1 , I I I I I I I I I I I I I I CDIII r::xecutiv9 Summary these acth.rities to rninirnizc the pOl:enUal for introduction of exotic sl')ecles should be ernploy'ect hnwever, entry of other exotic species into the SFRVVS reservoir s:ystern cannot be conti'ollc,d by SPRvVS alone. lnvasive species could be trat1sfcrred into the SPRWS reservoir system by the general public through activities such as boati-ng or fishing. Control Points In order to implement the Plan, control points were identified at critical locations witbin the SPRWS system that are 1) potential points of entrance or spread for zebra mussels and! or other invasive species, 2) potential points for the spread of zebra mussels to water bodies outside of the SPRWS system, or 3) facilities that are likely to require zebra mussel management as they are susceptible to impacts from infestation. The criteria used to detennine areas susceptible to zebra mussel infestation include: · Continuous exposure to currents that provides nutrients to feed zebra mussel populations; ~ Availability of firm surface(s) for zebra mussels to attach to; and . Presence of upstream impoundments with residence times sufficient to continuously provide settlement stage mussels. TIle control points that are critical to SPRWS' ability to meet its management objectives for zebra mussels and other invasive species are shown on Figure ES -1. Recommended Management Plan The Management Plan recommended for SPRWS incl udes three distinct components; monitoring for the presence and degree of infestation, education of the public and specific improvements for each management objective and conti'ol point. Monitoring SPR WS currently collects a considerable amount of data from the existing reservoir system, and should continue to collect and analyze the water quality data. In addition, SPR\IVS should consider rnaintainiIlg lTIOlutoring stations for zebra mussels in Pleasant, Suckcx and Vad~1ais Lakes ind.efin.i.telYI or at least l1J.l.til the infestatioTl reaches a steady. state to gauge changes to the level of in fes [:8 Lion.

Education of the Public Public education and notification has been a critical component of the DNR's invasive species programs. Coordination with the DNR, Ramsey County an.d the various communities surrounding th~ SPRWS reservoir system can be an effective component of SPRWS's zebra mussels and other invasive species management program and a valuable asset in assisting the DNR with their overall efforts. SPRWS should continue workin.g with the DNR and other interested parties to educate the public regarding potential transfer of zebra mussels and other invasive species into or out of the SPRWS reservoir system.

This has been a subject of joint interest of the St. Paul Regional Water Services (SPRWS) and Department of Natural Resources (DNR) ever since the designation of the upper Mississippi River with zebra mussels in 2005. SPRWS and DN"R have a good working relationship as we have worked through the issues associated with the zebra mussel infestation. The DNR is concerned that the study did not recommend a course of action to prevent the SPRWS from transferring new invasive species that will undoubtedly show up in the vicinity of your pumping operation. In particular, Asian carp are currently making their way upstream from Iowa. This species is not easily spread by recreational use, but would likely be transferred to the lakes used for water storage by the SPRWS operation. Additional invasive species and fish pathogens will likely present challenges in the future. The DNR fully understands that modifying the SPRWS operations to prevent future spread of invasive species will be an expensive undertaking and that the current evaluation did not identify ideal solutions. Nevertheless, we encourage SPRWS to continue to look fur long-term solutions through planning and evaluation of new technologies. The DNR is willing to provide staff support as needed in these efforts and would be willing to work with you to explore options for funding. We appreciate your interest in preventing the spread of invasive species. Please feel free to contact our Ecological Resources staff as they are. committed to continuing to work with you on these issues.
