Project / Issue Relates To: Collaborate with the City of Portland to make a financially and environmentally responsible long-term investment in a wastewater treatment facility. Issue before Council (Highlight Policy Question): ☒Council Goals/Priorities ☐Adopted Master Plan(s)☐Not Applicable ISSUE BEFORE COUNCIL EPCOR Foothills Water Project (EFWP) has completed the Preliminary Services Agreement (PSA) regarding design and site evaluation for a new wastewater treatment plant, which completes the PSA term. Staff seeks approval for reimbursement to EPCOR for its PSA costs. Staff is also seeking Council direction on the next steps for the Council Initiative to collaborate with the City 4.1 Page 2 503-635-0215 380 A AVENUE PO BOX 369 LAKE OSWEGO, OR 97034 WWW.LAKEOSWEGO.CITY of Portland to make a financially and environmentally responsible long-term investment in a wastewater treatment plant. Staff recommends exploring a competitive procurement (including special procurement and alternative contracting methods) method in lieu of proceeding with EPCOR Foothills Water Project (EFWP), primarily because staff finds it is likely a more economical method of delivering the project. BACKGROUND The existing Tryon Creek Wastewater Treatment Plant (TCWTP) was built in 1964 and is owned and operated by the Portland Bureau of Environmental Services (BES). The plant is reaching the end of its useful life cycle and needs to be upgraded or replaced. Since 2018, the cities of Lake Oswego and Portland have been actively exploring replacement of the existing Tryon Creek plant. Pursuant to Resolution 18-55, the Council approved a special procurement for the design, build, financing, operation, and maintenance (DBFOM) of a new wastewater treatment facility under a public-private partnership. Following a competitive DBFOM solicitation for qualifications and proposals, on May 4, 2021, the City entered into a Preliminary Services Agreement (PSA) for the DBFOM of a new plant with EPCOR Foothills Water Project, Inc. (EFWP). The PSA was originally intended to develop designs to the 60% phase as well as complete a large number of deliverables that include advancing permitting, scoping costs, developing schedule, completing archeological and environmental studies, and many other items. Under the PSA, EFWP advanced about $7.2 million for these costs, to be paid upon completion of the term of the PSA (or included in the Project Agreement financing). In April 2023, the Council authorized Amendment 1, extending the work under the PSA with EFWP for up to one year, during which EFWP advanced designs to a 90% level as well as completed a number of deliverables. EFWP has successfully completed the PSA. The cost for the Amendment 1 work was about $3.7 million, and was paid on an ongoing basis. DISCUSSION PSA Termination / Compensation to EWFP Under the PSA, the term ends upon completion of the Preliminary Services, including Additional Services (90% design) Compensation to EPCOR is due for the Preliminary Services unless the parties execute a Project Agreement. As discussed below, staff does not recommend the City execute a Project Agreement. Accordingly, Staff is recommending payment of the EFWP invoice (Attachment 1) because it accurately represents the amount of reimbursement due for EPCOR’s work (100%) based upon the formula in the termination for convenience clause. Continuation of Project Staff recommends continuing to move forward with the project as the original value proposition was to determine whether it was more beneficial to upgrade the existing Tryon Creek Wastewater Treatment Plant or build a new facility. The life-cycle cost estimate to upgrade the existing 1964 Tryon Creek Wastewater Treatment Plant is between $800 million and $1 billion, and the cost estimate to design (both cost for work done to date and expected to finish design), build, operate, and maintain a new plant with public financing is between Page 3 503-635-0215 380 A AVENUE PO BOX 369 LAKE OSWEGO, OR 97034 WWW.LAKEOSWEGO.CITY $592 and $622 million. In addition, there are a number of benefits to building a new facility as shown below. Visual 1: Project Benefits to Building a New Plant through a Public-Private Partnership (For more in-depth information, see http://www.lakeoswegowastewaterfacility.org/) Explore Competitive Procurement Methods, e.g., Alternative Contracting Methods, Special Procurement Staff recommends exploring a competitive procurement method (inclusive of alternative contracting methods and special procurements) for the next phase of finalizing design and constructing the new facility in lieu of proceeding with EFWP. There are two main reasons for considering a new delivery approach: 1. Financial Considerations: The proposed cost of private financing by EFWP would impose significant burdens on ratepayers. Public financing is more cost-effective and provides a better long-term value to the community. Lake Oswego prioritizes being good stewards of taxpayer and ratepayer dollars. The decision to use public financing and leverage the EPA Water Infrastructure Finance and Innovation Act (WIFIA) loan is a favorable long- term financial option, potentially saving millions of dollars for Lake Oswego ratepayers and, as a major customer, Portland ratepayers. 2. Increased Competition: A request for proposals to the engineering, construction, and wastewater operations industries would result in market-driven, competitive pricing. This approach is expected to reduce costs compared to the initial private financing DBFOM proposal. This method also will increase confidence that Lake Oswego received the best price possible as it will be reflective of current market conditions. Accomplishments and Products from Phase 1 Several achievements and products resulting from phase 1 can be applied to phase 2. These include: • Detailed facility design, environmental studies, and geotechnical reports. • Cost estimates and financial structuring. Page 4 503-635-0215 380 A AVENUE PO BOX 369 LAKE OSWEGO, OR 97034 WWW.LAKEOSWEGO.CITY • WIFIA loan approval. • Preliminary draft of Oregon DEQ discharge permit. • Intergovernmental Agreement (IGA) between Portland and Lake Oswego. • Public engagement and input. • Progress in property acquisition. EFWP Project Financing and Costs The below table shows how the costs have evolved from the start of the project until now. Note: The original proposal estimate was based on other projects within the market conditions of 2019 and 2020. The estimated cost for phase 2 under the DBFOM with EFWP was $704 million in November. Detailed information is available in Attachment 2, “Final Project Submittal Design-Build- Finance-Operate-Maintain (P3) New Wastewater Treatment Facility for the City of Lake Oswego.” Attachment 2 includes detailed information regarding the deliverables and EFWP’s cost estimates for the next phase. The EFWP costs for $704 million are summarized as follows: • Design-Build the New Plant: $189 million • Misc. Construction Items: $2.8 million • Operations & Maintenance for 30-years: $191.9 million • Cost for Private Financing net of Equity Contribution of $37.8 million: $138.8 million • Cost for Public Financing of $151.2 million (including WIFIA): $98 million • Land Acquisition & Demolition/Remediation of the Existing Plant: $53 million Cost Evolution for the Wastewater Treatment Facility Project Feb. 2021 Dec. 2022 Nov. 2023 Attachment 2 Dec. 2023 Dec. 2023 Staff’s Estimated Procurement Option Original Proposal EPCOR's Proposal at 60% Design EPCOR's Proposal at 90% Design City's Proposal (Rejected by EPCOR) EPCOR’s Final Offer Design-Build- Operate- Maintain w/ 90% Designs Design, Build, Finance, Operate and Maintain a New Plant for 30-Years $485 Million $724 Million $651 Million $561 Million $621 Million $539-$569 Million Land Acquisition & Demo/Remediate the Existing Plant w/financing $53 Million $53 Million $53 Million $53 Million $53 Million $53 Million Total Project Cost $538 Million $777 Million $704 Million $614 Million $674 Million $592-$622 Million Page 5 503-635-0215 380 A AVENUE PO BOX 369 LAKE OSWEGO, OR 97034 WWW.LAKEOSWEGO.CITY • Design Costs: $10.8 million • Consultant Costs: $4 million ($3.1 million spent so far) • City Insurance (30-years): $15.7 million Total: $704 million In further discussions with EFWP, staff received indications that private financing cost could be lowered from $138.8 million to $100.4 million based on a contribution of $15.3 million of EPCOR funds instead of the original $37.8 million investment. This may have reduced the overall project cost down by about $30 million to a project total of about $674 million. Next Steps and Schedule Staff recommends that the project continue to move forward with building a new facility, instead of Portland upgrading the existing Tryon Creek plant (with the attendant costs to Lake Oswego ratepayers, as Lake Oswego is the major customer). The next phase involves exploring a competitive procurement, such as a DBOM delivery method. This will extend the procurement timeline, and adjustments to the current design are likely. The City would conduct a thorough market outreach to identify potential DBOM entities (firms and teams) that would consider proposing on the project, with the ultimate solicitation methods including publication and direct outreach. Estimated DBOM Costs Staff believes that public financing will reduce costs to be between $592 and $622 million. Additionally, using a competitive procurement process will help the City get the most competitive construction and operations costs, factoring in performance reliability. A detailed cost estimate will be known after competitive submissions are received. The project team believes that the DBOM cost will remain within the planned Lake Oswego rate structure of 3.9% increase per year. Property Acquisition The acquisition of properties at 99, 101, and 113 Foothills Road is ongoing, unaffected by the change in project financing. The selected site was chosen based on its size, safety from flooding, and proximity to existing infrastructure. Relationship with EPCOR EPCOR responded respectfully to Lake Oswego's decision not to proceed with them for phase 2. While disappointed, EPCOR understood the city's fiscal responsibility and wished Lake Oswego success in its chosen path. Lake Oswego staff would like to acknowledge EPCOR for their work in planning and designing the facility, providing a solid foundation for the upcoming phases. Page 6 503-635-0215 380 A AVENUE PO BOX 369 LAKE OSWEGO, OR 97034 WWW.LAKEOSWEGO.CITY FISCAL IMPACT On May 4, 2021, the Council authorized the PSA. The preliminary services were performed and EFWP has advanced $7,171,092.12 to get to 60% design. The City now needs to reimburse EFWP for this amount (Attachment 1) so as to purchase the designs and deliverables. The City will need to make this approximately $7.2 million payment out of the Sewer Fund, which was not anticipated to be paid out of fund balance as this amount was originally envisioned to be covered under a bond issuance. However, there are funds available to make this payment. This payment will put pressure on the fund and may necessitate issuing a full faith & credit bond in the near future to pay for upcoming project costs. For all costs, Portland is responsible for 31% and Lake Oswego is accountable for 69%. All Payments since Project Start Category Cost EFWP: 0 to 60% Design* $7,171,000* EFWP: 60 to 90% Design $3,669,000 Consultant Spending $3,105,000 Property Acquisition and Relocation $1,473,000 WIFIA Application Fee $284,000 Total $15,702,000 *EFWP to be reimbursed upon Council’s approval. All of these costs resulted in deliverables that can be leveraged and reused in the final design and construction phase. The consultant spending table (Attachment 3) shows that about $3.1 million has been expended so far in the project, and there is a remaining $808,000 left on the contracts as a whole. Depending on the ultimate timeline and strategy the City chooses, the existing contract limits should be sufficient to get us most of the way to ground breaking.; however, depending on the timeline and strategy, there may be more money needed.

SUBMITTAL 1. INTRODUCTION AND BACKGROUND 1 | P a g e 1 Introduction and Background 1.1 Project Background The Cities of Lake Oswego and Portland are seeking a new and more efficient wastewater treatment facility to replace wastewater treatment service provided by the existing Tryon Creek Wastewater Treatment Plant (“TCWTP”), located in the City of Lake Oswego (“City”). The existing TCWTP, owned by the City of Portland and located at the confluence of Tryon Creek and the Willamette River, was constructed in 1964, expanded in 1976, and treats sewage collected from parts of southwest Portland, unincorporated areas of Multnomah and Clackamas Counties, and the City. As an alternative to upgrading the existing facility, the Cities are investigating the replacement of the existing plant with a new wastewater treatment facility (“WWTF”) that would treat current and projected flows and comply with all environmental and permit requirements on a reduced footprint. EPCOR Foothills Water Partners (“EFWP”) was selected to provide a definitive project submittal that includes the design, construction, equity financing, and long-term operation, maintenance, repair, replacement and management of a new wastewater treatment facility that will be owned by the City of Lake Oswego. 1.2 EFWP Preliminary Services Process and Deliverables In May 2019, EFWP was shortlisted along with two other teams in pursuit of the Progressive P3 delivery of a new wastewater treatment facility for the City of Lake Oswego, Oregon. In March 2021, EFWP was selected as the preferred proponent, and the parties signed a Preliminary Services Agreement (“PSA”) in May 2021. As part of the progressive P3 delivery model, the PSA allowed the project to progress to a 60% design and fixed price submission, after which the City would make a decision whether to award the final design, construction, financing and long-term operations of the project to EFWP. Between May 2021 and October 2022, EFWP completed Task 1 (Initial Development and Basis of Design Report), Task 2 (30% Design), Task 3 (60% Design), and Task 4 (Definitive Project Submittal – submitted in draft form). At the time of the Definitive Project Submittal (October 2022), it was anticipated that EFWP would be providing financing for the entire project, through equity, Water Infrastructure Finance and Innovation Act (“WIFIA”) loan, and privately-financed debt. This was at a time of rising commodity prices, supply chain issues, inflationary pressures and increasing interest rates. In early 2023, it was agreed-to between the City and EFWP to amend the PSA to advance the project to a 90% design level and delay the Go/No-Go decision on the project by one year, anticipating that market uncertainties and interest rates would improve over that time. Additionally at this time, the City agreed to transfer the WIFIA loan (49% of design-build costs) from EFWP to the City as well as replacing EFWP’s private placement debt (31% of design-build costs) with public financing through the City in order to realize savings from the lower rates of municipal bonds. PSA Amendment #1 was executed on April 10, 2023. Highlights during Task 5 included:  Preparation of 90% designs and specifications  Aqua Aerobic 90% design completed  Prepared updates to 3D model  Preparation of materials for the Sustainability Advisory Board  Prepared pre-application package for the Land Use Application  Participated in the Neighborhood Meeting on June 22, 2023  Submitted Land Use Approval application EPCOR FOOTHILLS WATER PARTNERS | LAKE OSWEGO WASTEWATER TREATEMENT FACLITIY P3 | FINAL PROJECT SUBMITTAL 1. INTRODUCTION AND BACKGROUND 2 | P a g e  ESA Phase I Refresh  Archeological Permit received and completed associated investigation work  Completion of Hazardous Material Building Survey at all 3 properties  Completed Solar Study and Recommendations  Information provided to DEQ to support NPDES permit transfer  Project Agreement redlines to reflect updated financing arrangement  Coordination with Portland General Electric to confirm design details  Inclusion of additional scope items including Lake Oswego Sewer Upgrade, Reclaimed Water Project, Solar Panels  Meeting with Oregon Energy Trust  Update to Operations and Maintenance plans  Update to Commissioning Plan and Interface Protocol Plan  Update to Permitting Plan  Update to Equity, Inclusion and Diversity Plan  Update to Project Quality Plan EFWP has solicited updated quotes from major equipment vendors. The entire open book estimate has been revised with the most up to date capital costs for the City’s consideration. At the same time, EFWP has updated and confirmed pricing in regards to Operations and Maintenance and Repair and Replacement costs. The market is still experiencing inflationary pressures and wage escalations, although there is less uncertainty than in October 2022. EFWP has worked collaboratively internally as well as with both the City as well as the City of Portland to provide the most cost-effective solution for the WWTF, while still ensuring optimum safety, reliability, redundancy and sustainability measures are in place. EFWP, with this Final Project Submittal is providing a commercial offer for the City’s consideration to award to EFWP the completed design, construction and long term operations of the project. This Final Project Submittal includes all the requirements set out in the PSA Amendment #1 and includes a 90% Design Submittal, Cost Submittal, Commercial Submittal, Technical Submittal, Additional Information Submittal, and Final Price Submittal.

EPCOR FOOTHILLS WATER PARTNERS | LAKE OSWEGO WASTEWATER TREATEMENT FACLITIY P3 | FINAL PROJECT SUBMITTAL 2. 90% DESIGN SUBMITTAL 7 | P a g e 2.2.3 Additional Preliminary Services (e) The need for any subsequent modifications or development of the final design beyond the 90% level will be determined by the City. If the City directs the Project Company to advanc e the final design beyond the 90% level, the Project Company shall be compensated for such advancement as an Additional Preliminary Service. If agreed to by the City, it is proposed that EFWP continue the design modifications and necessary site investigations to further develop the Portland sewer tie-in option proposed by the City and the City of Portland. EFWP currently estimates the additional capital cost to incorporate this design change is $1.0M (Class-5 estimate). It is also proposed that EFWP continue discussions with the City and its advisors in determining the level of alkalinity addition necessary for successful operation of the WWTF. Currently, alkalinity addition has not been included in either the Design-Build Price or Operations Charge. EFWP currently estimates the additional capital cost to incorporate this design change is $1.8M (Class-5 estimate). 2.3 Site Investigations 5.1.2 The following Site Investigations will be completed as part of Task 5: (a) Biological Assessment; (b) Archeological Assessment; (c) Solar Study; (d) Additional survey at the river and bathymetry for the HRLO; and (e) Phase 1 ESA (not necessarily needed but if not done again then new owner would most likely not qualify for federal grant opportunities such as for clean-up assistance if something is found). Refer to 90% Design Submittal – Attachments – 2.3 Site Investigations for the completed upland biological assessment. Refer to 90% Design Submittal – Attachments – 2.3 Site Investigations for a drawing outlining the archeological assessment field results. The archeological assessment field work was completed in October 2023 and the final report is expected in November 2023. Note that additional archeological investigations will be required to accommodate the revised design for the Portland Sewer Tie-ins. Refer to 90% Design Submittal – Attachments – 2.3 Site Investigations for the completed solar study and associated EFWP recommendations. Refer to 90% Design Submittal – Attachments – 2.3 Site Investigations for the topographical and bathymetry survey file for the high river level outfall (HRLO).

Refer to 90% Design Submittal – Attachments – 2.3 Site Investigations for the completed hazardous building material survey reports completed for all three properties. 2.4 Permitting Applications 5.1.3 The following permit applications will be submitted at or before completion of the 90% design as agre ed between Project Company and the City: (a) Land Use Application; (b) NPDES Permit; (c) USACE/DSL/DEQ Joint permit application; and (d) CLOMR-F application to FEMA (Necessary for WIFIA). (e) Demolition Permit; and (f) Building Permit. EPCOR FOOTHILLS WATER PARTNERS | LAKE OSWEGO WASTEWATER TREATEMENT FACLITIY P3 | FINAL PROJECT SUBMITTAL 2. 90% DESIGN SUBMITTAL 8 | P a g e The City will pay application and other fees charged by the permitting agency associated with the above permits. Note that site access is required for the Hazardous Building Material Survey, which is an input into the Demolition Permit (item e). This will be dependent on the land acquisition process by the City. Additionally, the Demolition Permit is a pre-requisite to the Building Permit (item f). Refer to 90% Design Submittal – Attachments – 2.4 Permit Applications for letter deeming the Land Use Application complete. All other documents associated with the Land Use Approval process, including the Pre- Application, Pre-Application Mailing, Pre-Application Meeting, Neighborhood Meeting and the Land Use Approval application (including information re-submittal), can be found on SharePoint (Task 5 – 90% Design  5.2 Permitting). It is currently assumed that a new National Pollutant Discharge Elimination System (“NPDES”) Permit is not required for the WWTF, and therefore an application has not been made. The City and the City of Portland are discussions with the Oregon Department of Environmental Quality to support the facilitation of a NPDES Permit transfer from the TCWTP to the WWTF. Refer to Table 5-2 in Section 5-3 for the anticipated permit application and approval dates for the USACE/DSL/DEQ Joint Permit Application (JPA), anticipated for March 2024, after the City Council Go/No-Go decision. For the CLOMR-F application to FEMA, this application can only be submitted once and the cut/fill information needs to be updated for the revised Portland sewer tie-in prior to submittal. EFWP has had discussions with the City of Lake Oswego Building Department and it was advised to apply for the Demolition Permit and Building Permit upon completion of the Land Use Process, so as not to incur additional review time and associated costs. These activities have been scheduled for after the Land Use Application Approval as well as after the City Council Go/No-Go decision.

Refer to Cost Submittal – Attachments – 3.1 Design Build Cost Documents for the detailed breakdown comparing the Design-Build Price in previous tasks to current. 3.1.1 Construction Cost Refer to Cost Submittal – Attachments – 3.1 Design Build Cost Documents for all subcontractor and supplier quotes. There have been several updates to the Design-Build Price which are now reflected in this Final Project Submittal. Pricing has been refreshed with current quotes, schedule has been refined to address any changes in scope, and the design has been updated to address the City’s feedback on the 60% and 90% designs. The Final Project Submittal also includes an updated design and corresponding estimate to address the outstanding technical issues as reviewed with the City and detailed in the following document, ‘Lake Oswego Wastewater Treatment Replacement Project - Outstanding technical items [Nov 3 2023]’. All items have been closed out except the following, which require additional investigation and effort to close out: • Updates to the generator sizing report require the vendor to update their model and reissue the report. Updated information has been provided to the generator supplier, the model is scheduled for the week of November 13, 2023 and will be provided to the City upon completion. • Relocation of the Portland sewer main tie-in to the North-West corner of the Tryon Creek lot is underway. Provided in Section 2.2.3 is a Class-5 capital estimate for this redesign. Additionally, but not found with the outstanding technical issues identified by the City, a design solution is currently being developed to address the influent alkalinity concerns. A Class-5 capital estimate has been provided in Section 2.2.3 for a make-down soda ash feed system with an integrated silo storage tank. The soda ash system and silo is currently anticipated to be located on the north boundary of the site adjacent the trash bins. To finalize the design, additional influent testing for alkalinity and TKN will be required to determine the appropriate and optimal sizing and for the chemical system.

COST SUBMITTAL 10 | P a g e Construction Pricing Update from 90% Design The culmination of changes from Task 4 to Task 5 has resulted in an increase of 7.7% to the total Design-Build Price. A review of the main changes driving this increase are summarized in the table below, the identified costs include 5% for Contingency and 15% for Mark-up. The table below is not meant to capture all changes but highlight the significant items incorporated over the period. Further details can be found in the sections below to explain some of the other Design-Build Price fluctuations. The following sections review the Final Project Submittal as it compares to the Task 4 Submission. The comparison is made between the divisional breakouts for each specified area (e.g., Treatment Area, Administration, and Workshop) and a detailed review is provided for any fluctuations or variance greater than $250,000.00. This Final Project Submittal is based on the information submitted with the updated 90% Design Drawings & Specifications, coupled with construction and design-based assumptions required to execute the work. The level of estimate, found below, varies throughout the work-breakdown-structure from a Class 2 estimate to a Class 1 estimate where more detailed information is available. This round of pricing has seen increased stability in line-material pricing, with moderate increase in equipment pricing and labor rates. The average increase to labor was close to 5% which equates to $2.5M increase to the project.

COST SUBMITTAL 11 | P a g e Contingency, Indirects, Design and General Directs The following section focuses on the Contingency, Indirects, Design, and General Directs. Contingency The Risk Register has continued to evolve throughout the Preliminary Services as more information becomes available and the severity or probability of risks have become better understood. There have been fluctuations up and down in the individual risk items over the period; however, with additional design development has realized an overall reduction in the risk exposure from the previous version. The current risk register, found in Cost Submittal – Attachments – 3.1 Design Build Cost Documents has assessed the risk between the lower allowance of $4.9M and the upper allowance of $10.5M. The current contingency value of $7.4M represents a savings of $2.3M from the previous iteration and falls within the risk register lower and upper allowances provided above. Indirects The indirects for the Project have had some significant changes since Task 4. The following provides a summary and rough order of magnitude for the three significant changes found within the Indirects section: • Letter of Credit – the letter of credit has been removed from the Project requirements providing a savings of $550K at the Design-Build cost level. • Insurance – the current market for Professional Indemnity and Project Specific Professional Liability (PSPL) insurance is strained. The PSPL market, for water and wastewater treatment facilities specifically, is limited in capacity and identified as a poor risk category for insurers – this is indicated in the pricing received. Insurance has provided the largest increase to the costs, adding $4.75M to the Project (at the cost level) and accounting for just over 35% of the total increase from Task 4 to current. The team reviewed options with Marsh to see if a better solution was available but any adjustments to the extended reporting period or the deductible provided little improvement. EFWP open to discussing other solutions for the Project and will continue to review options with the insurance broker to see if any other opportunities exist. • Escalation – consistent with industry forecasts, the escalation has been reduced to 4.5% for the first year and down to 3.5% for every subsequent year after that. The escalation percentages have been consistently applied to each labor, material, equipment, and subcontracts, for a total reduction of $1.2M from the previous submission.

COST SUBMITTAL 13 | P a g e Division 2 – Site Works The updates to the 60% design included the addition of the Lake Oswego sewer upgrades, significant increases to the underground potable water scope, additional underground work for the primary electrical, and additional excavation for the structural changes and utility realignments. Coupled with the additional earthwork quantities required for the change to scope, a detailed volumetric analysis was completed by the modelling team to properly sequence the excavation and backfill activities required on site. The volumetric analysis identified the total quantity of earthwork at 90,000 cubic yards, an increase of 32% from the previous submission. One of the main reasons for this increase, outside of the noted design changes is the space constraints on site, the limited space requires significant double handling of material (e.g., backfilling areas to allow the course of construction to continue, that then must be re-excavated again later) with almost all material having to be trucked offsite, stored, and eventually returned for backfill. Multiple bids were solicited for the earthwork; however, only one proponent provided a price for this scope, representing an increase of $3.6M. The outfall scope has been modified from the 60% design which accounted for a savings of $700K. The primary reason for the change was the removal of the pneumatic pinch valve for an electric butterfly valve which allowed for a smaller chamber at the edge of the river and eliminated the compressor building and equipment. The volumetric analysis also revealed additional bedrock excavation and cutback slopes that encroached on existing structures and into the steep hill on the west side the property towards State Street. To account for these clashes and mitigate against undermining concerns, shoring was added to the budget for an additional cost of $500k. Additional bedrock removal was required for the new waste activated sludge (WAS) and Reuse tanks and adjusted for quantities under the solids building. The improvements in the underground electrical price were primarily attributed to redesign and elimination of the underground ductbank. The modifications represent a savings of $600K. The following provides a breakout and rough order of magnitude associated with the changes provided above: 1. Scope & Supply Increase for all Earthwork (includes trenching for utilities) – $3.7M 2. Scope & Supply Increase for rock blasting – $360K 3. Scope & Supply increase for underground utility yard piping - $500K 4. Scope decrease for outfall upgrades - $700K 5. Scope increases for Shoring – $470k 6. Scope decreases for underground electrical – $600k Division 3 – Concrete From the 60% submission to the 90% submission the concrete design increased rebar densities to account for the new structural code changes, incorporated two additional process tanks and increased the depth of the screened influent channels. The increased rebar quantities of 412,000 lbs were offset by more competitive supply/install rates of $1.03/lbs versus the previous quote of $1.21/lbs. With everything else largely remaining the same the additional costs were found in concrete supply and the additional concrete required for the WAS and Reuse Tanks. The following provides a breakout and rough order of magnitude associated with the changes provided above: 1. Supply decrease for Rebar – $200K 2. Supply increases for concrete – $200K 3. Scope increase for WAS and Water Reuse Tanks – $550K EPCOR FOOTHILLS WATER PARTNERS | LAKE OSWEGO WASTEWATER TREATEMENT FACLITIY P3 | FINAL PROJECT SUBMITTAL 3. COST SUBMITTAL 14 | P a g e Division 8 – Openings Division 8 remained largely the same from Task 4 to Task 5 except for the retractable openings on the AGS basin. The previous design contemplated removable hollow core panel for maintenance access to the basins; however, further discussions with the hollow core suppliers persuaded against using hollow core for this application. The retractable cover provides everyday access to instrumentation for the operations team, and provides easy access for maintenance (i.e. does not require a crane to remove the panel). The additional costs for the retractable covers is partially offset by the savings to the hollow core panels (~$80K). The following provides a breakout and rough order of magnitude associated with the changes provided above: 1. Scope increase for retractable covers – $480K Division 11 – Process Equipment In general, the supply of process equipment continued to see moderate increases across the market from the previous Task 4 submission, with larger increases for the supply of the UVs, grit removal equipment, and the odor control equipment. AquaNerada and AquaStorm pricing held firm from the previous submission. The current 90% design added an intermediary WAS tank to provide a more consistent feed through to the rotary drum thickeners to improve the overall operability of the thickening system; the addition included 4 more mixers, and two additional RDT feed pumps. With the added scope, the larger supply increases noted above, the general increase across the board for the equipment supply, and increases to the labor rates, Division 11 experienced an increase of $1.6M in the period. The following provides a breakout (of the largest fluctuations) and rough order of magnitude associated with the changes provided above: 1. Scope increase for WAS Mixers and RDT Pumps – $180k 2. Supply cost increase for the UV System – $400k 3. Supply cost savings for the Perforated Screens - $240K 4. Supply cost increase for the Grit Removal System – $130k 5. Supply cost increase for the Odor Control System – $100k 6. Supply increase for Labor (Filanc quote) - $900K Division 15 – Mechanical / Plumbing The updated Division 15 Mechanical design experienced modest scope increases from 60% to 90% design. Overall, the Mechanical price increased $740K which is mostly attributed to a modest increase in the HVAC supply costs as well as an increase to the supply and install costs for the remainder of the work within the division. The following provides a breakout and rough order of magnitude associated with the changes provided above: 1. Supply cost increase for HVAC – $150k 2. Scope and supply increase Mechanical (Filanc Quote) – $600K Division 16 – Electrical, Instrumentation and Controls Division 16 experienced a large increase in the period which was the result of a number of smaller scope increases, with the exception of the solar for $390K which is now included in the overall pricing. The following provides a breakout and rough order of magnitude associated with the changes provided above: 1.

Supply increase for Labor - $230K Administration Area The following section focuses on the Administration Area of the facility, by division. Division 2 – Site Works The largest increase to the Administration Area costs is attributed to the addition of the rammed aggregate piers required under the foundation of the building. While there have been small movements within the various cost breakouts, the rammed aggregate piers account for most of the increase to Division 2. Division 7 – Thermal & Moisture Protection Quotes received back for Division 7 provided some savings in the roofing for about $130K but the wall cladding quotes came back substantially higher for an increase of $400k. Overall, the Division 7 costs increased by $270K.

These costs allow EFWP to operate within the guidelines outlined in Technical Submittal - Attachments. Refer to Cost Submittal – Attachments – 3.3 Operations Services Cost Documents for details associated with determining the operations and maintenance component of the Operations Charge. The Fixed O&M Worksheet provides a summary of cost categories or “accounts” in the “Summary” tab with a breakdown of number of employees, quantities and unit costs detailed in the “Detailed O&M” tab. All costs, quotes, and estimates are provided within the attachment on an open book basis. The “Summary” tab also provides the updates made since Task 4. The most notable changes in this budget is the removal of sludge hauling as this is now proposed to be performed on a per-unit basis (see Section 3.3.5) as well as the inclusion of external laboratory costs, after a detailed analysis was performed as outlined in the “Sampling and Analysis” tab. The Variable O&M Worksheet provides all non-routine replacements and overhauls less than the $50,000 threshold for Repair and Replacements. Based on the latest insurance team revisions to the draft Project Agreement in Commercial Submittal - Attachments – 4.1 Draft Project Agreement, EPCOR has provided the costing for the necessary insurance coverages during the operations period. This includes worker’s compensation, professional liability, and automotive liability. The Operations and Maintenance costs are marked up by the Operations Subcontractor Fee of 10% and escalated annually. EPCOR FOOTHILLS WATER PARTNERS | LAKE OSWEGO WASTEWATER TREATEMENT FACLITIY P3 | FINAL PROJECT SUBMITTAL 3. COST SUBMITTAL 20 | P a g e 3.3.2 Repair and Replacement Refer to Cost Submittal – Attachments – 3.3 Operations Services Cost Documents for the worksheet associated with determining the repair and replacement component of the Operations Charge. This worksheet contains the updated major equipment and asset list, based on the 90% design. The list also contains critical asset details, equipment criticality and equipment redundancy. Each line has been assessed to determine overhaul and replacement frequencies. These frequencies are based on equipment manufacturers, EPCOR Weibull data from similar facilities and EPCOR operator experience. Additionally, the cost (equipment, materials and labor) for overhaul and replacements are listed for each line and is based on the design-build installation estimate as well as equipment and activities at similar EPCOR facilities. For select and specialized replacements (i.e. blower overhaul, diffuser membrane replacement and filter media cloth), budgetary quotes have been obtained by the suppliers and are provided in this attachment. As the draft Project Agreement defines Major Maintenance, Repair and Replacement to be activities greater than $50,000, the sheet was then filtered to only include replacements or overhauls equal to or above this threshold amount. All other activities have been included in a variable component to the Operations and Maintenance costing. For further information on how the Repair and Replacement will be managed over the 30-year operating term, refer to the Repair and Replacement Plan in Technical Submittal - Attachments. The Repair and Replacement costs are marked up by the Operations Subcontractor Fee of 10% and escalated annually. 3.3.3 Electricity Passthrough Refer to Cost Submittal – Attachments – 3.3 Electrical Use Estimate, in which EFWP has provided details of its annual Guaranteed Maximum Electricity utilization costs, which will be incorporated into the Project Agreement. The cost of electricity will be paid as a passthrough by the City to the Project Company and not subject to a markup. The pass-through electricity component shall be equal to the actual amount paid by EFWP to its electric utility provider for electricity supplied to the WWTF and added to the Operations Charge during each billing period. The electrical usage by the WWTF will increase as the flow capacity increases from 2025 (7,117,116 kWh/year) to 2055 (8,060,008 kWh/year) as shown in the Electrical Use Estimate. For modelling purposes, the consumption was put on a straighline between 2025 and 2055, increasing by approximately 32,000 kWh each year. The 2055 electricity quantity to be used as the guaranteed amount is 8,060,008 kWh/year. 3.3.4 Natural Gas Passthrough Based on analysis completed by WSP, the annual natural gas usage of the WWTF is expected to not exceed 12,000 therms. The administration building is expected to consume 650 therms annually and the process buildings are expected to consume approximately 10,000 therms annually, assuming a set temperature 55 degrees Fahrenheit. The cost of natural will be paid as a passthrough by the City to the Project Company and not subject to a markup. The pass-through natural gas component shall be equal to the actual amount paid by EFWP to its natural gas utility provider for natural gas supplied to the WWTF and added to the Operations Charge during each billing period. The natural gas consumption is not expected to vary over the 30-year term and as such is held at 12,000 therms annually as the guaranteed amount. 3.3.5 Residuals Transportation Upon suggestion from the City, EFWP is proposing that the cost of transportation of residuals (sludge) be paid for on a per dry ton unit price of $190.00. The unit price methodology ensures no additional risk or costs are EPCOR FOOTHILLS WATER PARTNERS | LAKE OSWEGO WASTEWATER TREATEMENT FACLITIY P3 | FINAL PROJECT SUBMITTAL 3. COST SUBMITTAL 21 | P a g e built into this component of the Operations Charge and it incentivizes EPCOR to be efficient which has benefits to both the City and the City of Portland Columbia Boulevard Wastewater Treatment Plant. EPCOR intends to maintain a fleet of trucks and tanker trailers to perform the sludge hauling internally. At the beginning of the term, two complete truck and trailer units will be purchased using the Repair and Replacement budget. These units are estimated and budgeted to last approximately 10 years and will be replaced twice during the term of the 30-year term. A third unit is expected to be added to the fleet approximately ten years into the term. As per discussions with the City, new units will not be provided at the end of the contract but EPCOR will be required to ensure the units are in good working order. Purchase of the fleet is included in the Repair and Replacement budget. The unit price of sludge transported includes the labor, fuel and maintenance of the fleet. The unit price also covers the three full time equivalent employees that are required for the duration of the term to operate the fleet and provide the necessary coverage and reliability. The following assumptions were used in developing this unit price proposal:  Tanker size of 6,000 gallons  A round trip drive time of 70 minutes  30 minutes of loading time and 30 minutes of unloading time  Drivers would work a 10 hour shift that will include evenings and nights to avoid high traffic times of the day  The trucks and trailers will be stored on site along the west fence line when not in use Based on experience and advice from the City of Portland, it has been assumed the optimal concentration will be 4.5%. EPCOR intends to work with staff at the Columbia Boulevard Wastewater Treatment Plant to look for truck unloading efficiencies. Although a 7% density is permitted in the draft Project Agreement, it has been advised that this thickness is not feasible at this time. A 7% density level was assumed in the Task 4 submittal. The more the sludge is thickened, the fewer truck loads will be required and the lower the hydraulic loading on the Columbia Boulevard Facility. EPCOR looks forward to ongoing discussions through the term with the intent of finding mutual benefits that improve sustainability and reduce the overall environmental footprint. For modelling purposes, the sludge production values was put on a straighline between 2025 and 2055 contract values, from 2,383 dry tons in 2025 to 3,003 dry tons in 2055, increasing by approximately 21 dry tons each year. In comparing to expected sludge production values, EFWP believes these values to be conservative and have the potential to artificially inflate the price provided by the financial model. The detailed analysis worksheet on how this unit price has been derived can be found in Cost Submittal – Attachments – 3.3 Operations Services Cost Documents. Due to the reduced level of risk associated with the unit price approach to residuals hauling, EFWP is proposing to reduce the Operations Subcontractor Fee to 5% for this component of the Operations Charge. 3.4 List of Any Proposed Allowance Items 5.1.4 (d) If applicable and requested by the City, a list of any proposed allowance items, alternat e prices and unit prices; and As noted above in Section 3.3.5, the City and EFWP have proposed to price residual (sludge) transportation utilizing a unit price methodology.

The Capital Charge is calculated to allow EFWP to earn an after-tax Return on Equity of 10.54%. The relevant taxation assumptions used in preparing the Equity Financing Plan include: 1) Corporate Activity Tax (CAT) will be payable on all gross receipts/revenues of EFWP during the Term of the Project Agreement and includes construction revenue, Capital Charge, Operation and Maintenance Charge and the Repair and Replacement Charge. CAT is at the current rate of 0.57% on these gross receipts and is calculated after the annual $1 million exemption. 2) Metro Supportive Housing Services Tax (MSHT) will be payable on taxable income of EFWP during the Term of the Project Agreement as EFWP’s annual gross receipts will be in excess of $5 million. The current MSHT rate is 1%. 3) State Income Tax is payable on all taxable income of EFWP during the Term of the Project Agreement. Taxable income for each period during the Term will be reduced by the amount of CAT and MSHT for that period, as CAT and MSHT will be deductions from State Taxable income. State Income Tax is included at a rate of 7.6%. 4) Federal Income Tax is payable on all taxable income of EFWP during the Term of the Project Agreement. Taxable income for each period during the Term will be reduced by the amount of CAT, MSHT and State Income Tax for that period, as CAT, MSHT and State Income Tax will be deductions from Federal Taxable income. Federal Income Tax is included at a rate of 21.0%. Taxable income for both Federal and State Income Tax purposes is calculated based on taxable income for entire Term of the Project Agreement. For the operating period, taxable income is effectively the return on financing which EFWP will earn on its equity contribution (less allowable deductions for CAT, MSHT and Statement Income Tax as noted above). Accounting rules will require EFWP to recognize margin on construction activity during the construction period, even though no construction margin is contemplated in the Project Agreement. Based on similar transactions which EFWP’s affiliates have entered into historically, EFWP has included a deemed 3% non-cash construction margin during the construction period.
