ROLL CALL Commissioners Present: Bill Inge, Doug Keeler, Joe Pishioneri, Peter Ruffier and Faye Stewart Commissioners Absent: George Brown and Walt Meyer Staff in Attendance: Meg Allocco, Jolynn Barker, Katherine Bishop, Dave Breitenstein, Judy Castleman, Amber Fossen, K.C. Huffman (Legal), Tonja Kling, Kevin Kraaz, Shawn Krueger, Caleb Lennon, Barry Mays, Troy McAllister, Brian Millington (Legal), Josh Newman, Anette Spickard, Loralyn Spiro, Matt Stouder, Mark Van Eeckhout, and Greg Watkins CONSENT CALENDAR a. MWMC 6/10/16 Meeting Minutes MOTION: IT WAS MOVED BY COMMISSIONER KEELER WITH A SECOND BY COMMISSIONER STEWART TO APPROVE THE CONSENT CALENDAR. THE MOTION PASSED UNANIMOUSLY 5/0. PUBLIC COMMENT There was no public comment. Matt Stouder, MWMC General Manager, welcomed Peter Ruffier to the Commission. RENEGOTIATION OF CONTRACT WITH THE FRESHWATER TRUST VIA AMENDMENT FOR ECOSYSTEM RESTORATION AND REGULATORY CREDIT SERVICES (P80080) Josh Newman, Managing Civil Engineer, stated staff is requesting an amendment to the existing contract with The Freshwater Trust to add scope and fee that will support the MWMC's thermal load pre-implementation planning efforts. This effort is currently budgeted and represents about a third of FY17 thermal load mitigation pre-implementation budget. The work takes advantage of Eugene Water & Electric Board's (EWEB's) Pure Water Partners Program. EWEB is interested in developing source water protection restoration projects in the McKenzie watershed and in the middle fork Willamette. The existing Freshwater Trust agreement with the MWMC is for the Cedar Creek and Millrace project implementation. What staff is proposing to do is to use that contract as a tool to move MWMC Meeting Minutes August 12, 2016 Page 2 of 9 forward on several elements of thermal load mitigation pre-implementation planning work. The work involves three tasks as outlined in the second attachment on Agenda Item IV. Task 1. Temperature Credit Supply Analysis Task 2. Credit Cost and Opportunities Analysis Task 3. Permit Implementation Assessment and Support K.C. Huffman, MWMC Legal Counsel, clarified that it is not adding new scope to the contract but rather it is refining and updating the scope. What we originally said we are going to do is part of this scope. RESOLUTION 16-11: IN THE MATTER OF RENEGOTIATING THE EXISTING CONTRACT WITH INCUMBENT CONTRACTOR THE FRESHWATER TRUST FOR MWMC PROJECT P80080 — ECOSYSTEM RESTORATION AND REGULATORY CREDIT SERVICES. MOTION: IT WAS MOVED BY COMMISSIONER STEWART WITH A SECOND BY COMMISSIONER KEELER TO APPROVE RESOLUTION 16-11 . THE MOTION PASSED UNANIMOUSLY 5/0. President Pishioneri closed regular session at 7:38 a.m. and opened the executive session. EXECUTIVE SESSION: Hypochlorite Update The Metropolitan Wastewater Management Commission met in Executive Session pursuant to ORS 192.660(2)(h) for the purpose of consulting with legal counsel regarding MWMC's legal rights and duties in regard to current litigation or litigation that is likely to be filed, and to consider information that is exempt from public inspection pursuant to ORS 192.660(2)(f). President Pishioneri asked if any representatives of the news media were present or general public. There were none. Staff was allowed to attend the executive session. President Pishioneri closed the executive session at 8:05 a.m. and opened the regular session. CONSIDERATION OF CONTRACTOR CLAIM FOR P80057 MOTION: IT WAS MOVED BY COMMISSIONER KEELER TO AUTHORIZE STAFF TO CONTINUE WITH SETTLEMENT NEGOTIATIONS WITH EMERY AND SONS RELEVANT TO P80057. IT WAS SECONDED BY COMMISSIONER RUFFIER. THE MOTION PASSED UNANIMOUSLY 5/0. STRATEGIC PLANNING — DRAFT MISSION, VISION, AND VALUES STATEMENTS Loralyn Spiro and Amber Fossen, Communication Coordinators, presented the refined draft mission, vision, and values statements reflecting the feedback they received from the Commission at the June meeting. Ms. Spiro stated a mission statement is a declaration of an organization's core purpose and focus that normally remains unchanged over time. The word "metropolitan" was added to the draft mission statement. MWMC Meeting Minutes August 12, 2016 Page 3 of 9 Proposed Refined Mission Statement: To protect our community's health and the environment by providing high-quality wastewater services to the Eugene-Springfield metropolitan area. Ms. Fossen stated a vision statement is an aspirational description of what an organization would like to achieve or accomplish. The refined statement replaces "is" with "will be." Proposed Refined Vision Statement: The MWMC will be recognized as a leader in protecting water quality through sustainable and fiscally responsible practices. Ms. Spiro explained a values statement tells customers and employees where the organization stands and what it believes in. At the June meeting, the Commission expressed they had no changes to the proposed draft of the Values Statement. Proposed Values Statement: The MWMC is driven to provide high-quality services in a manner that will achieve, sustain, and promote balance between community, environmental, and economic needs while meeting customer service expectations. Values: • Clean Water • Protecting Community Health • Providing Excellent Customer Service • Sustain Environmental Stewardship • Collaboration with Partners • Maintaining Fiscal Responsibility Ms. Fossen said the next steps would be the following: 1. Staff recommends approval of the proposed refined draft mission, vision, and values statements 2. For regional wastewater staff to start implementing statements into project planning and documents such as the annual budget and communication materials; and 3. Continuing the Commission's work on strategic planning by sharing the approved statements with partnership agency elected officials. DISCUSSION: Commissioner Inge stated that he is still concerned about the omission of"Lane County" in the Mission Statement. He referred to MWMC's website (www.mwmcpartners.org) on the "About the MWMC" page. It talks about the community partnership and refers to the cities of Eugene and Springfield and Lane County. He asked if the reason "Lane County" is not being used in the Mission Statement is because it would refer to all of Lane County. Mr. Stouder replied that the Mission Statement is more of a geographic reference than a partnership reference; the Lane County area that is being served is inside the Urban Growth Boundaries of both of cities. Commissioner Ruffier proposed to preface the Mission Statement with "In partnership with Eugene, Springfield, and Lane County." The Commission agreed to change it to say, "In partnership with Eugene, Springfield, and Lane County, to protect our community's health and the MWMC Meeting Minutes August 12, 2016 Page 4 of 9 environment by providing high-quality wastewater services to the Eugene-Springfield metropolitan area. Commissioner Keeler proposed to change the value statement to say, "The MWMC provides high- quality services that achieves, sustains, and promotes balance between community, environmental and economic needs while meeting customer service expectations." Commissioner Ruffier asked if the MWMC is quantifying customer service expectations. Ms. Fossen replied no, it is a challenging thing to do. Mr. Stouder stated that staff is trying to channel the indicators that are in MWMC's budget document and this is a part of Key Outcome #5 ("Achieve and maintain public awareness and understanding of MWMC, the regional wastewater system, and MWMC's objectives of maintaining water quality and a sustainable environment.") Commissioner Ruffier said that the value statement seems to build a commitment that we will somehow quantify it so that we can check against customer service expectations. Commissioner Inge replied that the words, "is driven to" were used for that reason, quantification; "driven to" indicates that it is our aspiration. Mr. Stouder stated that "strives" could be substituted for "driven to." President Pishioneri added that it is our goals not necessarily a statement of fact. He likes it the way it is currently written so that we have room to grow. Ms. Spiro read back the refined Vision Statement: "The MWMC strives to provide high-quality services that will achieve, sustain, and promote balance between community, environmental and economic needs while meeting customer service expectations." The Commission agreed with the revised statements. OPERATIONS & MAINTENANCE BUILDING IMPROVEMENTS PROJECTS (O&M BIP) UPDATE Mark Van Eeckhout, Civil Engineer, stated that this project was started in 2013 with a Pivot Architecture study to look at the space needs of the treatment plant. The Pivot study showed that there were a couple of areas that needed to be addressed with support staff. It was decided to hire a consultant to go through a programing exercise to look at what is really needed for the next 30 years for support staff. Staff went through the programming exercise and came up with three alternatives which were presented to the Commission. Alternative #2 was selected and is currently approaching the 90% design. Alternative #2 includes three distinct work pieces (from a high level). 1) Construction of a new Water Quality Lab that sits between the existing Administration office building and the Maintenance building. 2) Upgrades and a substantial expansion to the southern portion of the Maintenance building including new locker space, new breakroom space, more computer space, and some upgrades to offices. As a result of the expansion to the south of the Maintenance Building, there are a number of process pipes that need to be relocated. This includes process piping such as the waste activated sludge lines. 3) Upgrades and expansion to the Administration Operations building, which will mainly be gutting of the inside of the building and relocation of Operations to the existing lab space. Additional conference space will be built in both the center of MWMC Meeting Minutes August 12, 2016 Page 5 of 9 the Administration building and also a new foyer entrance area on the north and west. With this comes, hopefully, the removal of the Industrial Source Control (ISC) trailer. Most of the staff that is currently in the ISC trailer will move into the new lab and a couple of staff will be relocated into the remodeled Admin building. Mr. Van Eeckhout stated that in July, MWA (the consultant) delivered the 90% design package. There were a number of comments on that package and as a result, the consultant is going to do a revised 90% deliverable by the end of August. An updated cost estimated was received at the 90% phase. The construction cost estimate is holding in line with where they were at 50%. Also, some of the soft costs were reviewed and were revised upwards within the complete estimate. Because of an unpredictable bidding climate and some the challenges that have been seen in other projects in the region, staff decided to add two bid alternatives that are deducts to the bid documents. The smaller deduct is the removal of the central conference rooms in the Administrative building (rooms 120 & 121); estimated scope worth, $400,000. The bigger deduct would be the elimination of the Administration Operations building upgrades (-$3.9M). These bid alternatives will allow the Commission at bid time, to either execute the fully programmed scope or to reduce the scope based on the bid results. The next steps are to continue to work on finalizing the 90% design and comment resolutions. In addition, staff will be working with the consultant to make sure they are coordinating with their sub- consultants. Staff recently toured the Lake Oswego Water Plant that was designed by MWA. They learned some lessons from what Lake Oswego had to go through which will help guide staff in MWMC's design. Mr. Van Eeckhout hopes to have the 100% design in fall 2016 and hopes to be in bidding in the winter. The construction project will be phased if the whole scope is done. That means the removal of the processing pipes will happen first then constructions of the Lab and the Maintenance building. Once those are done, staff will be located into those new buildings. The Administration building would be done last. DISCUSSION: Commissioner Keeler asked what the sum of the construction cost and soft costs total. Mr. Van Eeckhout said the sum is $17.5M (that is his best estimate right now). Commissioner Keeler asked if the total included contingency as well. Mr. Van Eeckhout said it includes some contingency within the construction estimate (5%). Commissioner Keeler appreciates the options for deducts but he doesn't like the large deduct option because it takes away a lot of what the Commission is trying to do, especially in terms of Operations and their command center. Commissioner Keeler asked if staff had looked at a deduction for moving from hard offices to cubicles. Mr. Van Eeckhout said it was looked at but was told that there was not a lot of cost savings in that option. He added that the area that would be targeted for that is the NW portion of the Admin building and the savings would be around $200,000. Mr. Stouder said at the 50% design, there was a large increase in the construction cost estimate and it was discussed with the Commission. There was concern but staff was directed to move MWMC Meeting Minutes August 12, 2016 Page 6 of 9 forward to the 90% design and continue in recognition of the bidding climate. The total project cost estimated at $17.5M includes the increase to soft costs. Staff came up with the two deductions and our current budget is at $14.9M. The thinking is that when we go out to bid, the Commission will have the option to decide whether to increase the budget to where the bid is at or incorporate some deduct options and how to do that. There are other factors in play and staff will probably bring a supplemental budget to the Commission soon. There is a savings in the cogeneration project by going with a rebuilt co-generator instead of a new one. The next topic today is about another concern we have with the medium voltage cables at the plant. There are a number of things in flux, but the budget was what we had as a best estimate early on in the project. It has increased and we have the opportunity to make some decisions in the future. Commissioner Ruffier said the buildings are for 30 years, has there been staffing assessments done for 30 years out and is there enough swing space built into the design to accommodate that. Mr. Van Eeckhout replied staffing studies had been done. In terms of swing space, that was not looked at specifically. The staff assessments showed a slight increase. Commissioner Ruffier asked if the proposed modifications and design are based largely on improving existing staffing efficiencies. Mr. Van Eeckhout replied that it does improve existing staffing space and allows for a lot of flex space. The thought being, if there was an increase in staffing you could potentially take some of the flex space and add cubicles to it. President Pishioneri asked what the dimensions are for conference rooms 120 and 121. Mr. Van Eeckhout referred to the floor plan but the dimensions were not on it. He guessed the size of the two rooms was double the size of the Willamette room. President Pishioneri asked if it would save a lot of money if they were done away with or made smaller. Mr. Van Eeckhout replied their purpose was to hold large gatherings such as all employee meetings or public gatherings. MEDIUM VOLTAGE CONDUCTORS Greg Watkins, Project Manager, showed a map of the medium voltage conductors that were installed at the plant in 1981. As part of the digester project, staff was considering some work that would require relocating some of these conductors, and wanted to make sure the conductors could handle that task. Brown and Caldwell looked at the original submittals and identified the type of conductors and went back to the manufacturer to see if there were any issues. The manufacturer indicated this particular cable has seen premature failures due to water treeing. That is basically cracks and splitting of the insulation which then allows for water incurring and shorting, and ultimate failure of the cable. A Portland company was contacted that specializes in testing electrical equipment. That company identified a few tests that could be conducted to better assess the condition of these conductors. They recommend to not test because in their professional opinion it would cause failure of the cables. This triggered discussion with management where it was then decided to assign a task, using the On-Call Engineering Service contract with CH2M Hill, to further investigate and confirm the condition of the conductors and to help staff identify some scoping of what could be a project and how to move forward. Mr. Newman said that CH2M Hill independently verified what Brown and Caldwell and the Portland Company had indicated. Staff was shocked to learn this as it is the backbone to the electrical transmission system. The status right now is that CH2M Hill has dug into all the information (plans, drawings) and knows all the different runs of the conductors. There are 19 different runs that terminate at different points. About one third of these runs are a single feed MWMC Meeting Minutes August 12, 2016 Page 7 of 9 which means if it failed that process would be out of power. The other two thirds are dual fed meaning if one side fails, it can be powered from the other side. Those are lower priority. Then among those two thirds, it was prioritized down further, depending on what kind of construction contingency would be required and how complex it would be to take it out of service and provide temporary power and so forth. Mr. Newman said that staff had received some cost information from CH2M Hill; around $5M to do the work. The work would be done in stages with the highest priority being completed first. Mr. Stouder added that there is flexibility on working it into the CIP five-year-plan starting with this year's budget cycle. Commissioner Keeler asked how many linear feet and is it underground. The reply was that it is all underground. Commissioner Keeler asked if it could go aerial, would that save money. Mr. Watkins said that the traffic routes would dictate that the aerial would have to be pretty tall for the equipment to pass through. It might trip into some of the conditional use as far as the neighboring areas. Commissioner Keeler asked if the excavation would involve a lot of work around the process pipes and countless interference. Mr. Watkins said that this is the opportunity to ask if the routes are the most strategic routes. Assuming they are, staff would more or less lay new conduit adjacent to the old; that way interferences and conflicts would be minimal. Mr. Newman added that the cable lubricant that was used for pulling the conductors during construction has apparently hardened over the years with the result that the conductors are locked into the conduits and removal will be difficult if not impossible. To the degree that there are spare conduits in the ground staff would use it otherwise staff would need to provide new duct banks. The duct banks are about two feet below the surface but not as deep as the process piping. Commissioner Ruffier asked if the secondary feed only powers part of the plant in case of loss of power. The answer was yes. Commissioner Ruffier asked is there any thought of upgrading to power the entire plant. Mr. Newman replied there could be an opportunity here to do a more comprehensive plan for redundancy. It was talked about but it is not part of the scope that is being presented. We are limited in how much work we can do within the confines of this contract. There are a couple places where there are receptacles to plug in to for emergency power generation. We don't have that coverage throughout the plant and it is something staff would like to expand to have that ability and it helps with the response time and the ease of getting the emergency power set up. Mr. Watkins said that if staff were to do a larger master electrical plan, the main switchgear and transformers that were installed at the same time would also be evaluated. Mr. Watkins thinks that they can be tested so a better condition assessment could be done to find out whether they will last 5, 10, or 15 years. This would wrap a more holistic scope of what staff needs to do and how to phase it. Commissioner Ruffier asked if there is a contingency plan in event of failure. Dave Breitenstein, AIC Wastewater Director, replied that the critical process treatment units throughout the plant have redundancy which is driven by the EPA requirements. Not all process areas have the redundancy. Mr. Watkins added that where there are not dual feeds, some have generator plugs MWMC Meeting Minutes August 12, 2016 Page 8 of 9 that staff can directly connect to. If there is an area that doesn't have redundancy or plugs, staff would be pulling a generator out and running cable across the ground. Commissioner Inge asked how bad the problem is. Is it like asbestos, you know it is bad but if you leave it alone you don't have much of a problem. Mr. Stouder said that it is different than asbestos; if you leave the cable, eventually it will fail. Mr. Watkins replied it is hard to say when it will fail; it could fail today or in 20 years. BUSINESS FROM COMMISSION, GENERAL MANAGER, AND WASTEWATER DIRECTOR Commission: • President Pishioneri said he learned a lot from the ACWA conference in July and appreciates getting to attend. He felt that he learned a lot of background information that would also help him as City Councilor. • Commissioner Keeler said that the ACWA conference is one of the best. It helps him with vision, to look ahead and what is important. • Commissioner Ruffier expressed his appreciation for being able to attend the conference on behalf of the Commission. He said the presentation on the Willamette River Partnership was depressing and it indicates that there are significant challenges ahead with regards to the regulatory environment and MWMC's potential permit renewal. • Commissioner Inge asked if anything had come about regarding the property that was for sale. Mr. Stouder replied no, but in October there will be an Executive Session on different pieces of property that may be of interest to the Commission. General Manager: • Mr. Stouder stated the ACWA conference was successful and the MWMC had four Commissioners attend this year. There was a lot of interesting conservations on water as well as on biosolids. One of the things he took away from the biosolids presentation was about exposures. A professor from the University of Washington presented the studies they did on land applications and biosolids. They studied to see what the exposure would be to a person who was spreading biosolids on a daily basis for twenty years or a career. They also studied the effect of drinking water every day that was running off a field (that had biosolids applied to it), into a stream, and was not filtered. The studies showed that there is not a lot there in regards to exposure; super low risk as in comparison to ibuprofen, acetaminophen, or the stuff in your tooth paste. One of the calculations was, if you were breathing in the biosolids every day, how that would compare to taking ibuprofen for a headache. To receive an equivalent dosage, you would have to be exposed 150,000 years to the biosolids. The detection levels are very small, the risk is super low. There is a perception issue and communication issue about how we communicate and the public's concern that if you can detect it, it must be bad. Science is starting to show otherwise. There were also good presentations on resiliency and earthquakes. • Janet Gillaspie, ACWA's Director, is retiring and she was given a nice send off at the conference. There will be a retirement party for Ms. Gillaspie on September 29th in Portland. • Commissioner Inge had asked about the Biocycle Farm's sign; it was taken down because it didn't meet ODOT's requirements on billboards. Staff looked into what temporary sign MWMC Meeting Minutes August 12, 2016 Page 9 of 9 requirements are. A temporary sign can be up for 60 days, 12 square feet is the size allowed without a variance and with a variance, 30 square foot. Thirty square feet would essentially be the size of a sheet of plywood. Mr. Stouder recommends doing the 30 square foot size as there is no cost for the variance and it would be more visible. If the Commission is interested in doing a temporary sign, it can be done. President Pishioneri asked if the temporary status is once a year or something else. Mr. Stouder replied he believes it is 60 days a year. President Pishioneri wasn't sure it was worth doing for 60 days. Commissioner Inge said he feels for the small cost it was worth doing —there is a benefit. The little bit of exposure here and there all connects. Mr. Stouder said that he would follow-up with Ms. Spiro and talk to ODOT to see if it will be something that will be fairly easy to do. If so, we can go ahead and do it. Ms. Spiro mentioned that we can put up a "V" shaped sign so there are actually two signs so you can see it from both directions. A discussion on what to put on the sign came out that less is more. If there is too much on the sign people can't read it as they go by on the road. • Commissioner Stewart asked why ODOT is telling us what to do on Lane County property. The answer was because it is visible from State Highway 99. Commissioner Stewart said there are signs down in Cottage Grove that are right on I-5. Ms. Fossen replied that she made the mistake of asking ODOT. Mr. Stouder said it also has to do with commercial versus non-commercial. Commissioner Stewart wants to challenge it; he said he could talk to a County Planner to see if there is some overlay. Mr. Huffman said he would look over the memo that was done by his firm on this subject to renew his memory. He thinks we already have some answers on file; he would just have to get back to Mr. Stouder about it. Wastewater Director: • Mr. Breitenstein stated that the MWMC was recognized by the National Association of Clean Water Agencies last month's at their major conference in Colorado with the Peak Performance Award Platinum 9. The award is for meeting all the permit requirements with effluent discharge for nine consecutive years. • Trail Smith, lead operator, was recognized by the West Coast Central Section of the PNCWA as Operator of the Year. • Earlier this year the Commission decided to rebuild the co-generator. All the quotes have come in and staff is getting ready to place the order. It takes about six months lead time and co-generator's 60,000 hours will occur near the end of February. Everything is on schedule. • The annual field application of biosolids will start on Monday, August 15, 2016. There are three sites planned for application, they are: the Biocycle Farm, Hofers farm on Meadowview, and a field just north of Junction City on Highway 99. ADJOURNMENT President Pishioneri adjourned the meeting at 9:20 a.m. AGENDA ITEM IV. Metropolitan Wastewater Management Commission SPRINGFIELD OREGON partners in wastewater management MEMORANDUM DATE: September 1, 2016 TO: Metropolitan Wastewater Management Commission (MWMC) FROM: Meg Allocco, MWMC Accountant SUBJECT: FY 2016-17 Supplemental Budget #1 ACTION REQUESTED: Approve Resolution 16-12 ISSUE The purpose of this memo is to request approval of Resolution 16-12 authorizing proposed supplemental budget requests for FY 2016-17. This is the first of three supplemental budgets processed each year to adjust for corrections and new information. DISCUSSION Fiscal year 2016-17 wastewater rates and budget amounts were based upon estimates derived from FY 2015-16 estimated expenditures, inflationary factors, projected debt and other considerations identified during the FY 2016-17 budget development process. Actual amounts often differ from estimates used during the budget process, principally because the budget development process takes place mid-year. Consequently, estimates for the future year are based on approximately six months' actual experience. As a result, certain adjustments are necessary at the beginning of a new fiscal year in order to reconcile actual prior year ending balances with budgeted beginning balances for the subsequent year. Staff now has final capital project costs and ending cash amounts for FY 2015-16. Below are recommendations regarding the unspent amounts to be carried forward to the current fiscal year budget, as well as adjustments to beginning cash balances. Operating Fund: • The Commission is requested to approve the increase to the Operating Reserve in the amount of$1,304,682 to adjust Beginning Cash. This transfer will align the FY 2016-17 Beginning Cash balance with the actual cash balance at June 30, 2016. • The Commission is requested to approve the carryover of$129,400 in Eugene Wastewater Operations. This request includes expenses for the fuel station stormwater containment system, water quality lab consulting, United States Memo: FY 2016-17 Supplemental Budget #1 September 1, 2016 Page 2 of 3 Geological Survey (USGS) water quality monitoring, asbestos/hazardous material inspections, water information management system (WIMS), and poplar planting cuttings that were budgeted for, but not completed in FY 2015-16. Capital Funds: • The Commission is requested to approve the transfer of$4,634,815 to the Capital and Equipment Replacement Reserves from Beginning Cash. This transfer will align the FY 2016-17 Beginning Cash balance with the actual cash balance at June 30, 2016. • The Commission is requested to approve the carryover of$116,529 unexpended FY 2015-16 Capital Projects funding to FY 2016-17. Capital projects are fully budgeted in the year contracts are entered into, with the understanding that the cash flow will, in many cases, span one or more fiscal years. Unspent budgeted funds for such projects are carried over to the following fiscal year. These carryover items include: Project Amount WPCF Lagoon Removal Decommissioning 89,650 Thermal Load Implementation I 59,550 Biosolids Force Main Rehabilitation 50,000 Sodium Hypochlorite Conversion 50,000 Thermal Load Pre-Implementation 47,527 Facilities Plan Engineering Services 31,172 Poplar Harvesting 26,712 Wet Weather Flow CMOM 15,000 Offsets for expenses that exceeded estimated actuals include: Digestion Capacity Increase (156,335) Operations Building Improvements (96,747) • In addition $489,626 is being returned to reserves for projects that were complete and/or did not need to carryover remaining budget. • The budget for Capital Outlay is being reduced from $5,670,000 in the adopted FY16-17 budget, to a revised $2,262,979. This budget includes the Biogas Cogeneration System project that is made up of the Engine Rebuild ($480,979), Digester related value added improvements such as switchgear, low pressure blower and waste heat radiators ($972,000) and engineering services for the Digester improvements ($200,000). Also in the capital outlay budget is the Residuals Aerator Tractor replacement ($410,000) and the Distributed Control system upgrade ($200,000). • The Commission is requested to approve the carryover of$81,042 in unexpended FY 2015-16 Major Rehabilitation funding to FY 2016-17. This carryover is for the Willakenzie Owosso force main air relief. Memo: FY 2016-17 Supplemental Budget #1 September 1, 2016 Page 3 of 3 • The Commission is requested to approve the carryover of$116,098 in unexpended FY 2015-16 Equipment Replacement funding to FY 2016-17. This carryover is for equipment items budgeted and in progress, but not purchased prior to June 30, 2016, including secondary screw pumps (2) and a 1 ton utility truck. System Development Charge Funds: • The Commission is requested to approve the transfer of$1 ,204,469 to the SDC Reserves from Beginning Cash. This transfer will align the FY 2016-17 Beginning Cash balance with the actual cash balance at June 30, 2016.

Metropolitan Wastewater Management Commission ^—A-k SPRINGFIELD - y.. OREGON partners in wastewater management MEMORANDUM DATE: September 1, 2016 TO: Metropolitan Wastewater Management Commission (MWMC) FROM: Josh Newman, Managing Civil Engineer SUBJECT: Glenwood Pump Station Update ACTION REQUESTED: Information Only ISSUE The 2004 Facilities Plan (and associated Capital Program project list) includes a project to increase the Glenwood Pump Station hydraulic capacity originally slated for FY 10/11. The timing of that project was re-evaluated as part of the 2014 MWMC Facilities Plan Update and pushed out to FY 18/19. However, the 2014 analysis recommended testing to verify the pump station's actual existing firm capacity (capacity with the largest pump off line). Accordingly, staff issued Task Order No. 2 under the Facilities Planning Engineering Services contract (P80090) for engineering support to verify the firm capacity and to better plan how and when the upgrades should occur. At the September 9th Commission meeting, staff will present the preliminary findings and discuss next steps. BACKGROUND The Glenwood Pump Station was constructed in 1995 with the expectation that it would receive build out peak flows from the sub-basins listed in Table 1 below. The sum of these flows added to a design peak flow capacity of 12.9 million gallons per day (mgd). The predesign report upon which the design criteria were based does not provide an estimate of the time required to reach build out. The largest peak flow (4.1 mgd) was estimated to come from the Lane Community College (LLC) sub-basin. However, the LLC sub-basin flow is outside of the current Urban Growth Boundary (UGB) of both Eugene and Springfield, and therefore, not included in current MWMC planning targets. Removing the LCC subbasin peak flow yields a total build out peak design flow value of 8.8 mgd. The pump station was designed with bays for four pumps. At the time of construction, two of the four pumps were installed with the expectation that the remaining two bays would allow for future expansion. The pumps discharge through a header and valve vault to two force mains; one 12-inch and one 20-inch. These force mains convey the Memo: Glenwood Pump Station Update September 1, 2016 Page 2 of 4 flow under the Willamette River and discharge to the East Bank Interceptor (EBI). Here, the Glenwood flow joins the rest of Springfield's flow and is conveyed by gravity to the Willakenzie Pump Station in Eugene.

However, the plan, which focused specifically on the needed improvements to the MWMC's treatment facilities, did not provide a basis for the timing of the project. That said, the Glenwood Pump Station Upgrade project, valued at $500,000 (2004 dollars) was listed to be constructed in the period FY 10/11. Since that time, the project has been deferred due to slower than anticipated redevelopment in the Glenwood basin. 2014 Glenwood Refinement Plan The City of Springfield has recently revised development planning for the Glenwood area. Accordingly, City planners have produced the Glenwood Refinement Plan with revised zoning designations and associated design codes, which have been adopted by the Springfield City Council. The planned capacity expansion upgrades (addition of pumps three and four) are necessary to support redevelopment of the Glenwood Area per these code changes. 2014 MWMC Partial Facilities Plan Update In the 2014 MWMC Partial Facilities Plan Update (PFPU), staff estimated the project delivery schedule for the Glenwood Pump Station. The assessment took into account Springfield's new Glenwood development code and anticipated rate of development. Based on the assessment, pump station upgrades were scheduled for implementation in FY 18-19. The estimated value of the project was $926,000. The PFPU also made the following recommendations: • Field testing of pump station to verify capacity • Further analysis of current peak wet weather inflow conditions • Addition of smaller pump to better fit the current inflow conditions • Replacement of existing variable frequency drives 1 Glenwood rate of development was based on Springfield planning staff estimates. The assessment details can be found in the 2014 MWMC Facilities Plan Update report. Memo: Glenwood Pump Station Update September 1, 2016 Page 3 of 4 Facilities Plan Engineering Services Contract (P80090) In January 2016, the Commission approved Resolution 16-04 allowing staff to negotiate a three-year contract amendment with CH2M for Facilities Plan (On-Call) Engineering Services with a not-to-exceed value of$210,000. The contract amendment was executed in February 2016. Task Order No. 2 of the contract amendment provides consulting services to evaluate the Glenwood Pump Station including field testing to verify firm capacity and model the system hydraulics. The system hydraulic model will be used to develop capacity improvement alternatives for the upgrades project. Field testing (wet well draw down tests) were completed in July 2016. DISCUSSION CH2M has issued their preliminary analysis of the field tests performed in July 2016 on the Glenwood Pump Station. The preliminary analysis is presented in Attachment 1. Five tests were conducted, which are described in Table 2. Key findings include: Table 2. Summary of Drawdown Tests Performed for the Glenwood Pump Station Test No. Pumps/Speed Force main configuration 1 1 Pump @ 80% Speed Both force mains open 2 1 Pump @ 100% Speed Both force mains open 3 2 Pumps @ 100% Speed Both force mains open 4 1 Pump @ 100% Speed 20" only 5 1 Pump @ 100% Speed 12" only In addition, CH2M used the available as-built drawings and information gained through discussions with staff to develop a hydraulic model of the system. These "system curves" plotted along with the manufacturers pump performance curves and the test results show how theoretical performance differed from actual performance. The following was concluded: • The pumps are performing in close agreement with the manufacturer's performance curves indicating that wear and tear on the pumps has been minimal reflecting good operations and maintenance practices. • Flow through the 12" and 20" lines (both open) with 1 pump running, and the 20" line alone with a single pump seem to match model predictions within a reasonable level of accuracy. • Flow through the 12" line alone, and the combined 12" and 20" lines with both pumps running, falls well below the estimated values of the model. This may be a result of some obstruction in the 12" line, incorrectly labeled pipe diameters reflected in the as built drawings, or a combination thereof. The pumps are normally operated with both force mains open. However, this results in pump operation at a relatively low efficiency. This is partly because the pumps were sized for substantially higher flows than are currently experienced under all but the most severe storm conditions. For this reason, there may be an advantage to adding more appropriately sized pumps in remaining pump stalls. In time, these could be replaced with larger pumps as the flows in the Glenwood area reach substantially higher levels. Memo: Glenwood Pump Station Update September 1, 2016 Page 4of4 NEXT STEPS Based on the preliminary results described above, staff recommends the following: • Investigate the 12-inch force main using closed circuit television (if practicable). • If corrective actions are deemed necessary and performed, repeat this same testing plan to reestablish firm capacity, and recalibrate the system model. If no action is required or achievable, the model can be calibrated based upon the previously run tests and used to evaluate pump station upgrade alternatives • Investigate current wet weather flows. While the pumps lack flow meters, historical hourly flow may be estimated through data available with the data logging and telemetry system implemented in 2014. This information was not available when the 2014 Facilities Plan Update analysis was completed. • Propose recommendations for timing and scope of upgrades to be performed at the Glenwood pump station to best serve the ongoing development of the Glenwood area.

Pump Performance Test and Evaluation (CH2M) Glenwood Pump Station Performance Test and Evaluation Technical Memorandum PREPARED FOR: Josh Newman/MWMC Todd Anderson/City of Eugene PREPARED BY: Brad Eagleson/CH2M REVIEWED BY: Dave Brunkow/CH2M, Alan Chang/CH2M DATE: 09/01/2016 PROJECT: Glenwood Pump Station Evaluation PROJECT NUMBER: 676897 Introduction The current firm capacity of the Glenwood Pump Station in Springfield Oregon is not known by Metropolitan Wastewater Management Commission (MWMC) and the City of Eugene maintenance (City) staff. Historical references are inconsistent, indicating that the capacity of each pump is between 3,472 and 4,800 gpm. The first value is from the vendor provided pump curve, while the second is written in city documentation. MWMC and the City are interested in understanding the firm capacity of the current configuration to help understand the timeline for future expansion. This memorandum summarizes the pump tests conducted at the Glenwood Pump Station and the hydraulic model developed to assist in predicting effects to the pump station's firm capacity if and when the system is modified (i.e. piping configuration changes or pipe size changes). Background The Glenwood pump station consists of two Ingersoll-Dresser dry pit pumps with 18" fabricated steel suction pipes and 12"fabricated steel discharge pipes that combine and eventually transition to ductile iron (DI) pipe.The pump discharge pipes connect to a 12"fabricated steel header that splits flow between 12" and 24"fabricated steel force mains that exit the building below grade. Both the 12" and 24" steel force mains transition to DI at the elbow where the pipe turns horizontal to exit the pump station. The 24" pipe transitions to 20" DI after exiting the building, and upstream of the valve box. Downstream of the valve vault,the 12" and 20" DI pipes transition to 14" OD SDR 17 and 24" OD SDR 19 high density polyethylene (HDPE) pipes, respectively, and cross underneath the Willamette River to an existing gravity discharge structure on the opposite bank.The 24"discharge pipe was originally designed for full build out, but early on in the history of the station it was believed that pumps were not able to keep up with flows and the 24"future line was tied in to increase the capacity of the station. The pump station has open spaces for 2 additional pumps. Hydraulic Model of Glenwood Pump Station Model Development Hydraulic Modeling software (AFT Fathom) was used to develop the hydraulic model of the Glenwood Pump Station and associated piping system. AFT Fathom is fluid dynamic simulation software package ATTACHMENT 1 Page 1 of 17 for used with incompressible fluids to calculate pressure loss (headloss) and flow distribution in piping systems. The pump station model is based upon the 1994 as-built design drawings by KCM that show pipe size, fittings, valves, lengths and elevations, and known pipe, valve, and fitting hydraulic characteristics. The model was used to develop theoretical system curves for the installed pumps, which were then used as the baseline for evaluating the pump test data. Using pump test data, the model was calibrated and used to estimate pump station performance for future flow conditions. System Curves The following theoretical system curves were generated from the model for the following scenarios, and are presented in Figure 1.1. • 12" force main with 1 pump in service • 20" force main with 1 pump in service • 12" and 20"force main with 1 pump in service 45 40 35 oN 30 25 U co 20 C 0 15 10 12"&20"Modeled Curve 20" Modeled Curve 5 0 12" Modeled Curve 0 0 1000 2000 3000 4000 5000 6000 7000 Flow Rate(gpm) Figure 1.1 Theoretical System Curves for 12",20",and 12" and 20"in Parallel Scenario Pump Testing Planning A comprehensive test plan was developed to understand the current capacity of the Glenwood Pump Station (see Appendix A). The test plan was designed to collect data points to develop the actual system curve for the 12"force main, the 20"force main and the combined 12" and 20"force main in service. ATTACHMENT 1 Page 2 of 17 Collecting data at shutoff head for one pump running at 100%, was used to verify the operating point on the pump manufacturer's pump curves. Prior to the conducting the pump tests, MWMC, the City of Eugene, and CH2M agreed to a more simplified testing approach focusing on the performance of the two force mains in operation together. This focused the study to the current firm capacity with a goal of developing a calibrated model for predicting pump performance or selecting future pumps when considering increasing firm capacity of the station. For this reason only tests 1, 2, 3,4, 5 and 6 of the original test plan were completed. The purpose of each test is provided below. • Tests 1, 2, and 3, provides data to develop the system curve for the combined 12" and 20" by looking at typical pump operating conditions, 80%speed. • Test 2 establishes the firm capacity of the pump station as it is currently operated by collecting data for one pump operating at 100%speed discharging into both 12" and 20" force mains. • Test 3 establishes the maximum capacity of the pump station by operating both pumps at 100% speed, discharging into both 12" and 20"force mains in service. This is the largest volume the pump station is capable of moving with both pumps in service. • Tests 4 and 5 establishes the firm capacity of the pump station as it is currently operated by collecting data for one pump operating at 100%speed discharging into 12" and 20"force mains, Test 4 and Test 5 respectively. The data was used to calibrate the hydraulic model. • Test 6 established the shut off head for each pump and was used as a final point to verify that over time the pumps have not lost capacity, and are still operating on their curves. Note that with the exception of Test 6, shutoff head, all other tests were conducted with isolation valves in the valve vault at 100% OPEN. The city installed pressure gauges on the suction side (0 to 15 psi), and on the discharge line (0 to 30 psi) of each pump and Doppler flow meters on both the 24" and 12" lines exiting the building. Flow meters were located on the second floor of the pump station. Pump shaft RPM was measured using a tachometer, and the control and VFD panels provided information regarding motor operating frequency, and water surface level in the wet well. The approximate working volume of the wetwell from the invert of the 36" influent sewer to the pump suction centerline approximately three feet above the wet well floor, is 20,800 gallons. Each foot of water depth above the elevation of the fillets contains approximately 2,600 gallons of water. Pump Test Observations Every time a pump is shut down, the force mains drain slightly as the hydraulic gradeline equilibrates to match the invert on the far side river embankment. The elevation of the invert on the near shore is approximately 430.17 ft, and the elevation of the invert at the discharge structure on the far shore at 427.32 ft. Once the combination air valve closes after pumps restart, the force main was assumed to be full and data collection commenced. To allow time for the air to be pushed out and the air relief valve to close, a period of 1 minute was allowed to pass before data was recorded. Values for flow rate, pressure, revolutions per minute, and wet well level were recorded in 15 second intervals As there was grating between the levels the start of data collection was coordinated by the person watching the speed of the pumps on the top level by synchronizing the timing of the activities on the levels below. Generally data was collected for a period of about 2 minutes. Results and raw data have been tabulated in Appendix B. ATTACHMENT 1 Page 3 of 17 Total dynamic head was then calculated using the equation below. (Gauge readings corrected to pump centerline elevation) Pump Head = (Discharge Gauge + Discharge Velocity Head) — (Suction Gauge +Suction Velocity Head). Pump Test Results Pump Performance Table 1.1 presents a summary of pump performance results and system operating conditions for each test.

The data points for each test are close to the manufacturer's published pump curves. The field measured value for shut off head is similar to the value on the manufacturer's published pump curve. These results suggest that the pumps are in good operating condition with minimal wear and likely reflects good maintenance practices.

Test 5 yielded a measured pump station firm capacity of 2,603 gpm through the 12" force main. The hydraulic model of this scenario estimates a flowrate of 3,380 gpm. The observed flowrate is 23% lower than the predicted flowrate and indicates there may be some kind of obstruction or restriction reducing the capacity of the 12"force main. System Curves Theoretical pump station system curves from the uncalibrated hydraulic model for the 12"force main, 20" force main, and 12" and 20"force main in parallel with one pump in operation are shown in Figures 1.3, 1.4, and 1.5. As expected the test data do not fall on the respective theoretical system curve. The difference is because the hydraulic model was based solely on as-built drawings,which does not reflect actual operating conditions such as solids buildup in pipelines, increased pipe roughness as a result of aging, air entrapment in high spots, modifications since the as-builts, and inaccuracies in as-built drawings. The model needs to be calibrated using test data to more accurately reflect actual conditions. Figure 1.3 is the theoretical 12"force main system curve assuming one pump in operation based on the uncalibrated system hydraulic model and Test 5 data.

Hydraulic System Model Calibration The developed hydraulic model estimates the theoretical behavior of the piping system. If the system was built according to the 1994 construction drawings the uncalibrated model should represent the piping system performance typically within 10%deviation from actual values, in this case flow rates. Large deviations between predicted and observed values indicate some issue with the installed piping systems. Reasons for deviation could include blockages in the line, increased internal pipe roughness, or elements that were not built according to the original construction drawings. Several items are worth noting in regards to deviation of the actual system performance from the predicted system performance. • Table 1.2 shows the 12" force main alone,Test 4, deviates the greatest from the model (23%). • Two pumps discharging through the combined 12" and 20" force mains (Test 3) deviated from the model by 18%. • The difference between the predicted flow and observed flow for the 20" force main (Test 4) is 10%. These results indicate that there may be some issues with the 12"force main.

Other modifications were also made to each pump's discharge piping. Conclusions and Recommendations The pumps appear to be in good working order and are operating close to the published manufacturer's pump curve. The firm capacity of the pump station is 4,048 gpm as currently operated with both 12" and 20"force main in service. With only the 12"force main in service, the firm capacity is 2,603 gpm. Test data on the 12" header results in a flow that is 23% lower than the predicted flow, and shows flow characteristics of a smaller diameter pipe. Additional investigation of the 12" force main is recommended to check for obstructions. The following activities are suggested: • At a period when there are greater flows into the pump station, run both pumps into the 12" header alone to increase line velocity and see if there is a reduction in operating pressure over the duration of the test indicating a possible clearing of an obstruction or accumulated sediment. • Although the line would require dewatering, the line should be inspected with a camera to see if there is any line collapse or accumulated debris. Modifications to the piping would need to be made to isolate the 12" pipe from the 20" pipe so that the pump station can be kept in service. Rerun Test 4 to see if the resulting flow is closer to the theoretical flow following the flushing and visual and inspection and cleaning activities. If a significant change is observed and is similar to the theoretical flow, redevelop the system curves for the 12" and 12" and 20" combined piping system. • The hydraulic model should be recalibrated using the future 12"force main data and updated calibrated system curves generated. These updated curves can be used as a basis for selection of a different size pump which might permit operating at a higher efficiency point for more of the pumping year.

Pump discharge pipes connect to a 12" ductile iron header that splits flow between ductile iron 12" and 24" force mains that exit the building below grade. The 24" pipe transitions to 20" after exiting the building, and upstream of the valve box. Downstream of the valve vault, the 12" and 24" pipes transition to SDR 17 and SDR 19 high density polyethylene (HDPE) pipes, respectively, and cross underneath the Willamette River to an existing gravity discharge structure on the opposite bank. The 24"discharge pipe was originally designed for full build out, but early on in the history of the station it was believed that pumps were not able to keep up with flows and the 24" future line was tied in to increase the capacity of the station. The pump station has open spaces for 2 additional pumps. MWMC and City of Eugene maintenance (City) staff do not know the firm capacity of the Glenwood pump station in Springfield Oregon. Historical references are inconsistent and states that the capacity of each pump is between 3472 and 4800 gpm. The later value is from the vendor provided pump curve. MWMC and the City are interested in understanding the capabilities of the current configuration to help understand the timeline for future expansion. A theoretical model of the system has been created in Fathom based upon the as-built design drawings created by KCM.This model will be used in the effort to help troubleshoot and understand the system based upon collected data. Site visit On June 16, 2016 CH2M engineers (Brad Eagleson and Dave Brunkow) met with the City to visually inspect and gather data for the analysis of the Glenwood pump station. From the piping and valves that could be seen it appears that the station has been built according to the design drawings. Several items were noted and are described below based upon conversations, observations and comparison to the theoretical model. Each pump has a 12" APCO cushioned swing check valve (part no. 6012-1)on the discharge line. The operators expressed concern that these check valves do not appear to fully open when the pump is on. ATTACHMENT 1 Page 10 of 17 One of the operators showed that the weighted arm could be pulled into the fully open position, but the current flow rate does not seem to be sufficient to fully open the valve. V The valve box for the effluent piping contains a sewage air release valve for each of the 12" and 20" lines. When the pumps turn on air can be heard exiting this valve.This is to be expected as drawings show the piping in the valve box being 3.7 feet higher than the discharge piping to the gravity discharge structure on the other side of the river. Air is expelled as the pipe is filled from this high point down to the at-rest water surface in the inverted run of piping below the river. When the pumps shut down, air is pulled into the line thru the valve as the water level falls to meet the invert level on the far side of the river. While the station was designed to maintain a setpoint wetwell water surface using VFDs and PLC control, it is currently being operated in an ON/OFF duty/standby configuration. This change is mainly to prevent the pumps from ragging up as the slower speeds can be a source of clogging. There was some question as to whether the VFD is currently being used or not. The operators seemed to be under the impression that they were running the pumps as full speed (60 Hz), but the data coming into the VFD package indicated that they were running at 53 Hz (88%). From their experience the operators suggested keeping pump speeds at greater than 70% (42 Hz) to prevent clogging. The pressure gauge on the discharge line of the pumps appear to read between 12 psi and 17 psi. This is significantly higher than indicated in the model. The theoretical model shows the discharge pressure closer to 10.8 psi. This higher discharge psi seems to match well with "Pump Test Results" provided by the city of Eugene, but may be an indication that there is some blockage in the line or some unknown added head loss in the system.There is a plugged tap for an additional gauge on the suction side, but there is currently no gage installed. ATTACHMENT 1 Page 11 of 17 80 80 bid � 100 60 f �0 ra 40 11 1� 140 ? 160 16 The control system is currently set to turn on when the level in the wetwell is 110" and to turn off when the level reaches 85". It is not clear whether the reference point for this water level is from the bottom of the pump suction line or from the bottom of the wetwell itself. It was not possible to observe the HDPE piping at the outlet of the valve vault, but it may be useful to verify its size and specification as it is a common error in hydraulic calculations to assume a nominal ID based upon the OD line size without considering the relatively thick wall thickness of HDPE piping. With one pump operating,through both the 12" and 24" discharge lines, velocities in the 24" line could be as low as 1.8 ft/s at the original design criteria of 3500 gpm.There is a potential risk for sedimentation when velocities are less than 1.5 ft/s. Sedimentation is of particular concern because it decreases the flow area of the pipe, which would decrease pipe capacity. The low point of the force mains is underneath the Willamette River. Sedimentation will slowly reduce the cross sectional area over time, which would result in a gradual reduction in flow. At the low velocities with one pump running, sedimentation may have little impact. However, as flows increase and approach design velocities, sedimentation could have a significant impact on the line capacity. As neither pump makes excessive noise there are no initial indications that there is cavitation in either of the pumps, and based upon the 85" low set point for the wetwell it is unlikely that vortexing is an issue. The pump crew noted that the water level could be pulled down to a point close to the inlet elevation of the pump suction bells before loss of prime. Testing Procedures: Testing will require the city to install pressure gauges on the suction side (-3 to 15 psi), and on the discharge line (0 to 30 psi) of the pumps and transit time flow meter on either or both the 24" and 12" lines exiting the building. There is an available tap for the pressure gauges that can be utilized. The ideal location for the flow meter would be at least 5 diameters of pipe away from the wye connection in the vertical position.There is a possible location for the flow meter on the second floor of the pump station. Liquid temperature can be taken with a thermometer in the wetwell. ATTACHMENT 1 Page 12 of 17 Pump shaft RPM will be measured using a tachometer, and the VFD panel should be able to provide information regarding power, and operating frequency.The VFDs can be adjusted to several different speeds if necessary to get more complete understanding of the system. The approximate working volume of the wetwell is 24,000 gallons, from the invert of the 36" influent sewer to the pump suction centerline approximately three feet above the wet well floor. Each foot of water depth above the elevation of the fillets contains about 3000 gallons of water.The duration of the overall test effort will largely be a function of how quickly the wet well refills after a drawdown. Every time a pump is shut down,the force main drains slightly as the column of water falls to match the invert on the far side river embankment. Once the combination valve in the valve box closes after pump restart,the force main should be full and data collection can commence. Pump Testing The pump tests are designed to collect data points to develop the system curve for the 12"force main, the 20" force main and the combined 12" and 20" force main in service. In addition, by collecting data at shutoff for one pump running at 100%, a check can be made on previously collected data verifying the pump curves. See the sketch attached showing how these points should work together to develop both the force main system curves as well as the pump curves. Data points 1, 8, 9 and 10a form the pump curve for two pumps running at same time while data points 2,7,10 and 10a are the points that should agree with the manufacturer's performance curve for a pump. The sequence of the test points presupposes that it is more time efficient to change the number of pumps in service or their speed than it is to switch between force mains in service. The proposed test conditions are as follows: Note that with the exception of 10a, shutoff head, all other tests are conducted with isolation valves at 100%OPEN. Data will be collected in a table similar to that shown below. 12" and 20"force main • Test 1: Maximum capacity of the pump station discharging into the 12" and 20"force main. Both pumps operating at 100% speed. • Test 2: Firm capacity for the pump station discharging into the 12" and 20" force main. One pump operating at 100% speed. (Note: this test could be repeated with the other pump to confirm that the two pumps are operating similarly). • Test 3: Data point on system curve for the 12" and 20" force mains with one pump operating at 90% speed. • Test 4: Data point on system curve for the 12" and 20" force mains with one pump operating at 80% speed. 20"force main • Test 5: Data point on system curve for 20" main with one pump operating at 80% speed. • Test 6: Data point on system curve for 20" main with one pump operating at 90% speed. • Test 7: Firm capacity for the pump station discharging into the 20" force main. One pump operating at 100% speed. • Test 8: Maximum capacity of the pump station discharging into the 20"force main. Both pumps operating at 100% speed. 12"force main ATTACHMENT 1 Page 13 of 17 • Test 9: Maximum capacity of the pump station discharging into the 12" force main. Both pumps running at 100%speed. • Test 10: Firm capacity for the pump station discharging into the 12" force main. One pump operating at 100% speed. • Test 10a: Shut off head for one pump. Slowly close discharge isolation valve with one pump running at 100% until flow goes to zero. Repeat for other pump to check similarity in operating performance. • Test 11: Data point on system curve for 12" main with one pump operating at 90%speed. • Test 12: Data point on system curve for 12" main with one pump operating at 80%speed.

Metropolitan Wastewater Management Commission ^—A-k SPRINGFIELD - y.. OREGON partners in wastewater management MEMORANDUM DATE: September 1, 2016 TO: Metropolitan Wastewater Management Commission (MWMC) FROM: Katherine Bishop, Environmental Services Program Manager SUBJECT: System Development Charges Review ACTION REQUESTED: Informational ISSUE A review of the MWMC System Development Charges (SDCs) is in progress to evaluate and refresh the data inputs that result in the SDC fee amounts to ensure equity and fairness. BACKGROUND AND DISCUSSION SDCs are impact fees that are generally collected when expansion, new development or intensification of use occurs on a property served by municipal infrastructure (wastewater, stormwater, transportation, etc.). SDCs allow for the accumulation of capital funding needed to provide sufficient capacity in infrastructure systems to accommodate the growth associated with development/redevelopment. SDCs also provide the ability to recoup a portion of the community's investment in existing infrastructure. On September 11 , 2009, following a 90-day public notification process and public hearing, the Commission adopted the 2009 MWMC SDC Methodology via Resolution 09-15 for the MWMC Regional Wastewater System serving the Eugene-Springfield metropolitan area. Each year thereafter, the MWMC SDCs are adjusted for inflation based on the Engineering News Record (ENR) Cost of Construction Index (CCI). The 2009 MWMC SDC Methodology (46 pages in length; located at http://www.mwmcpartners.org/AboutMWMC/Documents/2009-SDCupdate.pdf) continues to meet Oregon Law requirements and was developed with the guidance of a Citizen Advisory Committee appointed by the MWMC. As such, the current evaluation is focused on refreshing the data inputs using the established 2009 MWMC SDC Methodology. For example: Memo: System Development Charges Review September 1, 2016 Page 2 of 2 1. Financing and interest charges associated with revenue bonds and the Clean Water State Revolving (SRF) loans will be refreshed to reflect current data. 2. Prior analyses have updated the original 20-year project list, established with the 2004 MWMC Facilities Plan, with actual costs for capital projects completed through 2009. This review will update the project list to reflect actual project costs (for completed projects) through fiscal year 2016. 3. This review will capture planned capital projects with current cost estimates and will add any new capital projects to the SDC project list to incorporate into the SDC calculation. With assistance from Galardi Consulting modifications, if needed, to the SDC model will be made to integrate the new data into the SDC calculations using the model developed in 2009 (and updated to 2016 for inflationary adjustments). The current SDC fee schedule is attached. At the September Commission meeting, staff plans to discuss the SDC review currently in process, and will return to the Commission this fall with more detailed information. ACTION REQUESTED Information for discussion purposes, with no formal action requested.

Metropolitan Wastewater Management Commission ^—A-k SPRINGFIELD - y.. OREGON partners in wastewater management MEMORANDUM DATE: September 1, 2016 TO: Metropolitan Wastewater Management Commission (MWMC) FROM: Todd Miller, Environmental Management Analyst SUBJECT: Pure Water Partners Update ACTION REQUESTED: Information only ISSUE The MWMC is positioned to formalize its collaboration with the Eugene Water and Electric Board's (EWEB's) "Pure Water Partners" program through an intergovernmental agreement (IGA). The IGA would define the administrative and funding relationships between the MWMC and EWEB for future development of temperature mitigation credits in the McKenzie and upper Willamette watersheds. EWEB staff plans to seek Board approval for funding the Pure Water Partners program over the next six months. Therefore, MWMC staff will be seeking Commission approval of the IGA in early 2017. This memo provides an update on the Pure Water Partners opportunity and benefits. BACKGROUND Under Oregon's revised temperature standard (adopted in 2002), the MWMC will be required to reduce or mitigate its temperature impact on the Willamette River by at least 93 million kilocalories per day (MKcal/day) of thermal load. That number is expected to increase should the DEQ impose stricter applications of the numeric criteria. The three-phase recycled water/thermal load mitigation planning studies (started in 2011) recognize that water quality trading credits (i.e. riparian shade projects) are a key strategy for the MWMC's thermal load mitigation portfolio. The Phase 2 study concluded that trading credits appear to be the most scalable and cost-effective option for thermal load compliance. The MWMC has been piloting riparian shade sponsorship projects with landowners along Cedar Creek as well as the Springfield Mill Race project. The Mill Race planting project started in 2013 and the Cedar Creek projects were planted in 2015/16. The Memo: Pure Water Partners Update September 1, 2016 Page 2 of 3 Freshwater Trust (project contractor) calculates these 20-year pilot projects will result in the credit equivalent of 10 MKcal/day. EWEB's Pure Water Partners program, initially piloted as the McKenzie Voluntary Incentives Program (VIP) for drinking water protection, presents an outreach opportunity in the McKenzie and upper Willamette watersheds whereby landowners may participate in riparian shade projects to generate temperature offset credits for the MWMC. In 2014-15, The Freshwater Trust evaluated EWEB's pilot VIP project for alignment with MWMC needs and determined one of the suitable pilot sites had a shade credit potential of 20 MKcal/day. To better understand the opportunity to identify landowners with high capacity to generate temperature offset credits, in January 2015 the MWMC entered into a memorandum of understanding (MOU) with EWEB to collaborate on developing the logistics of the partnership. The MWMC entered into the MOU recognizing that, upon positive developments of the program, the next step would be a formal IGA with EWEB to define scope, jurisdictional responsibilities and project administration needs. In August 2016, the Commission authorized a contract amendment with The Freshwater Trust to evaluate the credit production potential in the Pure Water Partners service area, the probable cost of implementation, and the regulatory crediting pathway under the Pure Water Partners framework. The intent of this amendment is to provide needed technical evaluation for developing the Pure Water Partners IGA. DISCUSSION This November, EWEB staff will be presenting a draft proposal to their Board to fund the Pure Water Partners program for the next 10 years. Pending Board feedback and discussion, EWEB staff would return to their Board in February 2017 for final approval. The MWMC has been an ongoing participant in collaborative planning of the Pure Water Partners program, and our interests are identified in work to date. The partnership work group is currently identifying the funding and administrative framework under which the program would be facilitated. The fiscal management structure currently proposed by the work group designates Cascade Pacific Resource Conservation & Development agency2 to manage partner funds and reimburse program expenses related to each partner. While the IGA would not need to commit the MWMC to a specific level of riparian restoration work at this time, staff expects that a certain level of cost-sharing will be needed to ensure the MWMC's interests are maintained throughout EWEB's initial landowner outreach efforts Credit value is calculated at a 2:1 ratio (i.e. 50% of the modeled shade value is creditable). Incentives for better trading ratios may be agreed to with the DEQ under its Internal Management Directive for trading. 2 Resource Conservation & Development agencies (RC&D's) were formed by the United States Department of Agriculture (USDA) in the 1960's to help aid and empower rural communities. Cascade Pacific was one of the first ten RC&D's in the nation. Cascade Pacific provides fiscal sponsorship and non-profit management services for groups, agencies, organizations, and other non-profits. Memo: Pure Water Partners Update September 1, 2016 Page 3 of 3 and site characterizations. Fiscal details will be firmed up as staff negotiates the draft IGA with EWEB. The Freshwater Trust is currently finishing its initial evaluation of credit potential and implementation costs in the Pure Water Partners service area, and staff will present updates on those findings at the September 9, 2016 commission meeting. RECOMMENDATION Staff recommends negotiating a draft IGA with EWEB to formalize the MWMC's role in the Pure Water Partners program. Staff intends to bring the proposed IGA to the commission for approval in early 2017. ACTION REQUESTED No action is required of the commission at this time. Staff welcomes any input on negotiating the draft IGA with EWEB.
