Leslie Crittenden, Deputy Town Clerk To: cc: From: Date: Subject: TETRA TECH TECHNICAL MEMO Michael Brack, Fraser Town Manager Joe Fuqua, Paul Johnson, Logan Wray, Jim Fox, Buff Boreas, Ben Miller, PE, Mark Maxwell, PE Jenna Barker, PE November 1, 2023 Upper Fraser Valley Wastewater Treatment Plant Management of Influent High -Strength Load Wastewater The Upper Fraser Valley WWTP (WWTP) received a Compliance Inspection Report from the Colorado Department of Public Health and Environment (CDPHE) in June 2023. The inspection findings indicate that, "local industrial pretreatment user standards have not been developed or enforced". Based on the Discharge Monitoring Reports (DMRs), the WWTP has reported multiple instances of influent TSS and effluent ammonia concentrations in exceedance of the permit limits since 2021. A follow-up inspection is tentatively planned for summer of 2026. Based on conversations with the EPA Region 8 and CDPHE, it is recommended that a Commercial Pretreatment Program (CPP) is implemented prior to this date to avoid future infractions and state or federal intervention. Effluent concentrations of ammonia in exceedance of the permit limit were recorded in two instances, February 2021 and December 2022. Ammonia concentrations from collection system composite samples, collected during the December 2022 noncompliance event, exceeded the influent average by more than three times. As documented in the Response to Upper Fraser Valley WWTP Evaluation Recommendation (Tetra Tech, 2023), acute high -strength ammonia loads were received at the WWTP during this event. Ammonia -oxidizing bacteria (AOBs), responsible for the reduction of wastewater ammonia concentrations, are relatively slow -growing and less -diverse than the remaining heterotrophic, nutrient reducing bacteria. AOB growth rates inhibit the WWTP from treating rapid increases in ammonia loading, which resulted in challenging and reactive plant operations to mitigate impacts, and in some instances, noncompliance with effluent limits (Feb 2021 and Dec 2022). Mitigation of acute, high -strength discharges to the collection system and WWTP will reduce the likelihood for future violations. BOD5, or biochemical oxygen demand, is the summation of nBOD, nitrogenous biochemical oxygen demand, and cBOD, carbonaceous biochemical oxygen demand. nBOD is the BOD that ammonia exerts on the wastewater. Increases, or a sudden influx of ammonia concentrations result in an overall increase of nBOD further increasing the overall BOD of the wastewater quality. The 2001 JFOC Agreement states that an equivalent residential unit (EQR) "represents a maximum day load of 270 gallons and 0.6 lbs BOD5". Table summarizes the reported EQRs sold by each district/town (EQR Summary Report - 15t Quarter 2023) and their calculated BOD loading based on the EQR allocation of the JFOC Agreement.

The WWTP is responsible for reporting the 30 -day average influent BOD concentrations. One influent sample is collected per 7 -day week. Table 2 summarizes the minimum, maximum, and average values for the 7 -Day (weekly) BOD concentrations in 2022 and the resulting, calculated EQRs (0.6 lb BOD/day per EQR). Table 2. 2022 Calculated EQRs Average 1,190 1,983 Maximum J 4,624 7,706 Results of this analysis suggest that the Upper Fraser Valley WWTP is receiving maximum daily BOD loading in excess of the reported EQRs sold by each district/town (EQR Summary Report -1St Quarter 2023). In other words, the maximum influent loading reported at the WWTP in 2022 was equivalent to 7,706 EQRs, if using the JFOC allocation of 0.6 lbs BOD/day per EQR. This is 1,512 more EQRs than reported as sold in the 1st Quarter 2023. The number of EQRs calculated from the maximum BOD loading received at the WWTP, indicates that during these high -loading events, approximately 90% of its initial reserve capacity (8,518 EQRs) is being reached. On average, approximately 23% of the initial reserve capacity is being reached indicating that management of the high -strength discharges to the collection system, via a Commercial Pretreatment Program, may reduce the noncompliance events experienced at the WWTP and resolve the discontinuity between reported EQRs and calculated EQRs. The implementation of a Commercial Pretreatment Program may lead to one or a combination of the following actions: 1. Commercial dischargers implementing best management practices to manage and limit discharge of high strength waste into the collection system. 2. Town of Fraser -enforced municipal ordinance that may restrict the high -strength loading discharges of commercial users (CUs). 3. CUs and WWTP collaboration in management of wastes. 4. Reallocation of EQRs between the towns/districts of the JFOC to better plan for necessary infrastructure expansions or modifications to accommodate the peak loading concentrations. It is recommended that a Commercial Pretreatment Program be developed and implemented prior to the tentative 2026 CDPHE facility inspection in an effort avoid further violations and to reduce the peak loading concentrations experienced at the WWTP. To maintain treatability, protect existing infrastructure, and adequately plan for future WWTP expansion, it is critical to quantify the number EQRs currently discharging to the WWTP. CDPHE suggests plant expansion planning to begin when a facility reaches 80% of its maximum month rating. It is recommended that the JFOC consider reallocating the number of EQRs initially reserved for each town/district to accurately reflect the maximum loading received by each jurisdiction at the WWTP. Table 3 depicts the Initial Reserve Capacity in EQRs for each district/town belonging to the JFOC and the calculated percent of allocation reported as of the 1st Quarter of 2023. Table 3.

Project Understanding IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII The development of a formal pretreatment program was requested to proactively manage commercial and industrial discharges and comply with the state/federal regulations set forth in the discharge permit held by the Upper Fraser Valley Wastewater Treatment Plant (WWTP). To mitigate future violations and assist the Joint Facilities Oversight Committee (JFOC) and the WWTP in their responsibility to protect existing infrastructure and the Fraser River water quality, a Commercial Pretreatment Program (Program) will be developed and implemented over the next few years, prior to 2026. The Program will aim to: • Educate commercial users (CUs) within the JFOC service area while establishing a strong relationship between the CUs and JFOC for successful program implementation and acceptance. • Document CU's processes, discharge practices, and discharge water quality that will influence the development of a practical and successful pretreatment solution. • Using this collected data, perform alternatives analyses and assessments that will identify ways to proactively manage the industrial discharges. • Reduce impacts to the collection system and WWTP infrastructure caused by discharges received by known CUs within the JFOC service area. • Draft Pretreatment Ordinances to be amended into the Town of Fraser Municipal Code and accepted by the JFOC in the Upper Fraser Valley Wastewater Treatment Agreement. • Maintain established relationships with the CUs, best management practices for discharge reduction or water quality improvement, required record keeping and reporting as recognized ordinances amended into the Municipal Code. Implementation and development of the Program has been divided into three phases: 1. Phase 1: Outreach and Data Collection 2. Phase 2: Process Solution and Pretreatment Ordinance Development 3. Phase 3: Record Keeping and Administration Due to the potential variability in the outcomes of each Program Phase, this scope of services will be amended, as desired by the JFOC, following the completion of each phase. The anticipated scope of services for each phase is described herein and will be updated following the completion of each Phase. This scope of work is for Phase 1 tasks only. Scope of Services IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII The Program implementation Scope of Services has been separated into the three phases as presented in the Commercial Pretreatment Program Development and Implementation Recommendation (attached). For the successful completion of each phase, the following high-level tasks have been identified. Task 0: Project Management Project management services associated with executing the Program, including project initiation, project coordination, and project administration will be conducted throughout the duration of Program implementation. Tetra Tech's Project Manager will monitor team performance for scope, budget, and schedule. Tetra Tech will submit monthly invoices detailing expenditures incurred in conjunction with the Program implementation. Each invoice will cover a period of one calendar month (a four -week or five -week duration) and will be submitted within thirty days after the end of each billing cycle. Phase 1 Meetings: 1. Virtual Program kick-off, 1 -hour Phase 1 Deliverables: 1. Monthly invoices 2. Meeting agenda and minutes for Program Kick-off PHASE 1: OUTREACH AND DATA COLLECTION Task 1: Commercial User Identification and Categorization Existing CUs within the service areas of the JFOC districts will be identified and categorized on type of discharge and anticipated WWTP process impacts. Tetra Tech will utilize JFOC district records on current Equivalent Residential (EQR) or business records, and desktop available resources to identify CUs. CUs will be mapped using GIS. Tetra Tech will create educational materials consisting of a brochure or flier to provide each CU based on the categories of CUs identified. The informational material will be drafted and delivered to the JFOC for comment and revision prior to finalization. Tetra Tech will categorize identified CUs on type of discharge as well as willingness to partner with the JFOC on the development and implementation of this Program. CUs that have the ability to pilot best management practices (BMPs) as part of the Program development, will be identified in their categorization record. Tetra Tech will develop a standard questionnaire, record keeping method, and approach for communicating with the CUs. Task 2: Commercial User Outreach and Education Tetra Tech will conduct initial, in -person communications with CU's identified to have critical discharges. Tetra Tech will provide educational materials completed in Task 1. During initial communications, Tetra Tech will aim to capture any concerns of the CUs and to learn of processes that may potentially impact the collection and treatment processes operated by the JFOC. During the initial visit Tetra Tech will schedule a second follow-up visit with each of the critical CUs. The follow-up visit will be performed to better understand processes and potential functional BMPs that should be explored further to benefit the discharge water quality. The JFOC will be notified of the outreach dates and times but are not expected to be in attendance. Task 3: Water Quality Sampling Plan Tetra Tech will produce a sampling plan and coordinate with the WWTP staff to perform collection system samples at a designated time of discharge from these CUs. It is anticipated that several samples will be necessary for each critical CU connection. The JFOC staff will have an opportunity to review the plan prior to executing as part of Phase 2. Phase 1 Meetings: 1) Bi-weekly progress meetings (1 -hour each) held virtually or in person as described under Assumptions. 2) Two JFOC Board meetings, to be attended in person. Phase 1 Assumptions: 1. Bi-weekly meetings will occur for the duration of this phase between the Tetra Tech Project Manager and members of the JFOC. These will occur virtually unless site visits are planned, in which case in person progress meetings can be arranged. It is assumed that no more than 18, 1 -hour progress meetings will occur. 2. Communications between Tetra Tech and critical CUs will occur in person. a. EQR and tap connection records, documentation, and maps will be provided to Tetra Tech from the JFOC districts upon request to identify/categorize CUs. If the District's maintain records for ongoing Fats, Oils and Grease (FOG) and amalgam pretreatment, these will also be provided to Tetra Tech for review and record keeping. b. Non -brewing or distilling CUs will not require in -person meetings, email/phone correspondence is assumed sufficient for these CUs throughout the duration of this phase. Based on a preliminary record search, Tetra Tech anticipates that there are no more than 40 total CUs existing throughout the service areas of the JFOC Districts. c. At the request of the JFOC, one open house can be scheduled inviting the CUs to attend an informational session regarding the WWTP and challenges faced with high concentration wastewater quality. Tetra Tech will facilitate the presentation for the open house at one of the JFOC offices. d. Communications with the non -brewery and non -distillery CUs will not require additional in person visits. Any follow-up communications performed via email or mail. 3. Communications with the critical CUs (no more than nine total CUs) will require in person, follow-up, and maintenance communications. It is assumed that no more than five visits per CU will occur prior to the next phase of the Program. Each visit is estimated as follows: a. Initial: One visit, 1 hour per CU (9 hours total) b. Follow-up: One visit, 2 -hours per CU (18 hours total) c. Maintenance: Three visits, 1 hour per CU (27 hours total) d. It is estimated that half of the CUs will require additional time for outreach and education to ensure that there is positive communication and to establish a strong partnership. An additional 30 hours is estimated to be designated for any of the initial, follow-up or maintenance visits. 4. The WWTP staff will conduct water quality sampling for each of the critical CU collection system connection points based on the approved Sampling Plan. The Sampling Plan will outline the number of samples per connection point recommended to understand the impacts of the CUs. Phase 1 Deliverables: 1. Meeting agenda and minutes for progress meetings (assumed 18 total) 2. Map of identified CUs (Task 1) 3. Educational brochure or flier (one) to be delivered to the CUs (Task 1). 4. Draft and Final versions of the CU questionnaire (Task 1), to be modified based on JFOC feedback 5. Compiled CU records including (Task 1, 2, 3) a. Finalized questionnaire b. CU identification (discharge and willingness to partner) c. Photo logs d. Summary of CU processes e. Summary of CU limitations f. Summary of outreach communication per CU 6. Sampling Plan (Task3) ENGINEERING FEE Tetra Tech proposes a time and materials engineering fee for Phase 1 of the Program development and implementation. The initial Phase has been estimated to include Tasks 1 through 3, with associated Project Management (Task 0). This Scope of Services may be amended at the completion of Phase 1 for Phase 2/3 services and fees. This will allow Tetra Tech and the Town to better understand the level of effort for Phase 2 and 3 tasks, and for better scoping and budgeting for these phases to occur. Tetra Tech's engineering fee associated with the Phase 1 scope of services is provided on the attached fee proposal. Work will be invoiced monthly on a time and materials basis with NET 30 payment terms. A detained fee breakdown and billing rate schedule is attached.

The Town anticipates a hospital to come into the District service area within the coming years. Tetra Tech will include provisions for this additional discharge within the Municipal Code ordinance changes as part of Phase 2, if requested by the JFOC. Tetra Tech assumes that some of the CUs may require additional partnering efforts. While Tetra Tech has made an effort to account for this in their fee and scope, if additional effort is required above and beyond the basic assumptions documented throughout this Scope of Services, a cost change may be discussed and arranged. AUTHORIZATION Tetra Tech is prepared to initiate this work upon notice to proceed from the Town. Authorization to proceed can be made by an approved agent of the District in the form of a signed Purchase Order. Additional services that are not included within this Scope of Work can be provided under a separate or amended purchase order, as directed by the Town. We appreciate the opportunity to participate in this exciting project and offer our services to the District.
