REGION 5 inspector Jake Berger joined me for the inspection and we both presented our credentials to the Water and Wastewater Manager Jonas Wilcox ("Manager") and informed him that this was a REGION 5 inspection to determine compliance with the Clean Water Act (CWA) and the National Pollutant Discharge Elimination System (NPDES) permit program. The inspection was conducted under the authority of the Federal CWA (Section 308). The table above identifies the attendees that participated in the inspection. This report is based on information supplied by Facility representatives, observations made by the Region 5 inspectors, and records and reports maintained by the permittee and the Region 5 inspectors, including: direct observations made by the Region 5 inspectors, photographs taken by Region 5 inspectors, physical evidence collected by the Region 5 inspectors, verbal or written statements made by or information supplied by Facility representatives (the permittee) during or subsequent to the on-site inspection, and materials, processes, data, photographs, or documents shown, demonstrated, or submitted to the Region 5 inspectors by Facility representatives during or subsequent to the on - site Inspection. In addition, information gathered prior to or subsequent to the inspection from a review of USEPA, State, and public records may be included in this report. After opening introductions, we went over the inspection plan for the day. I asked if there were any questions. The Manager had no questions. Facility/Site Description I began by asking about the Facility information provided in the latest NPDES permit. The Manager confirmed the following (Manager responses are in italics): There are three influent pumps that send the water to a 2mm fine screen. Correct an automatic sampler is located in between the pumps and drum screen. Correct Wastewater is then gravity fed into one of two membrane bioreactor (MBR) units. Correct. Collection system is all gravity. The water is then pumped through the three chambers located in the MBR unit where Aluminum Sulfate is added for phosphorus removal. Correct. Mixed liquor is then pumped into the filter unit located at the head of the MBR where it is filtered out at approximately 75 gallons per minute. Correct. (50-75 gpm) Treated water then flows through a UV disinfection unit where an automatic sampler is located. Correct. Water can be diverted into ponds around the building and/or has the option of discharging through Outfall 001 (Lat: 43.921478; Long: -83.906254) to an unnamed tributary to Saginaw Bay of Lake Huron. Correct. The plant has a design flow of 0.4 million gallons per day (mgd). At this time, the plant only processes approximately .025 mgd with an average of 1500 gallons of sludge wasted. Now up to about 0.058 mgd. The sludge is wasted from the filter area of the MBR with storage tanks located outside. The sludge is allowed to settle and the decant is brought back into the headworks. We try to decant as best as possible, return to head of the plant influent wet well. The sludge is ultimately taken to the Saginaw Chippewa Indian Tribe of Michigan's Isabella Reservation WWTP for treatment followed by land application. Correct, but currently looking to haul to City of Bay City. Any lift stations? One lift station at the head of the plant. Is a copy of the current permit onsite? Yes. 2 of 92 SAGANING WWTP Inspection Date: 08/25/2022 Facility/Site Information Responses below provided by the Manager.

Unit: Interview/DMR Review Observation #: DM1-OB-001 Contains CBI: No Date: 08/25/2022 According to NetDMR, no monthly discharge monitoring reports ("DMRs") have been submitted to EPA for the Saganing WWTP since September 2020. On May 18, I sent an email to the Manager asking to please submit all late DMRs as soon as possible. The Manager said he will try to submit the overdue DMRs by the end of the week after the inspection. In lieu of DMRs, I asked for copies of the last six months of sampling reports. The Manager provided copies of monthly sampling reports for January thru July 2022. Unit: Interview/Other Permit Reports Observation #: DM1-OB-002 Contains CBI: No Date: 08/25/2022 We reviewed non-DMR Permit reporting. The Manager provided the responses below. 1) Pollutant Minimization Program for Mercury Status Report due by January 31, each year (Part l.A.4). Status: The Manager was not aware of submitting the Mercury Status Report by January 31, 2022. 2) Operation and Maintenance Plan Report due by January 31, each year (Part I.A.7.b). Status: The Manager was not aware of submitting the O&M Report by January 31, 2022. 3) Sewage Sludge Removal Report by January 31, each year (Part I.C). Status: The Manager was not aware of submitting Sewage Sludge Removal Report by January 31, 2022. 4) As a condition of this permit, the permittee shall monitor the discharge from monitoring point 001 for the constituents listed below. Testing shall be conducted in September 2020, March 2021, May 2022 and July 2023. Status: The Manager said they probably haven't collected additional samples per this requirement. Total Kjeldahl Nitrogen (TKN) Total Dissolved Solids (TDS) Nitrate plus Nitrite Nitrogen Oil and Grease The Manager confirmed that records and reports are maintained for at least 3 years. Unit: Interview/Flow Measurement Contains CBI: No Observation #: DM1-OB-003 Date: 08/25/2022 The Manager answered the following flow measurement questions (responses in italics): 1) How do you measure daily influent and effluent flow (Permit Part I.1 and I.2)? Influent flow is measured by a mag meter; effluent flow is measured by a mag meter after each of the two MBR units. 2) Are influent and effluent flow measuring devices professionally calibrated, at least once per year? (40CFR122.41(e). Yes, they are calibrated every year. However, the last calibration was at the end of 2020, due to COVID. The Manager hopes to reschedule calibration for October 2022. 4 of 92 SAGANING WWTP Inspection Date: 08/25/2022 3) Do facility personnel check the calibration of the flow measuring device(s), between the annual professional calibrations, at least three times per year? (Recommendation only) If no, explain frequency. No. Unit: Interview/Self Monitoring Observation #: DM1-OB-004 Contains CBI: No Date: 08/25/2022 Unless noted otherwise, the Manager provided the responses (in italics) to the self-monitoring questions below: Are the influent and effluent sampling locations as specified in permit representative of the waste stream? Influent samples are collected at the head of plant at the pump control room. Effluent samples are collected after each of the MBR units. One autosampler (MBR #2) is out of service (approximately 1.5 years). Currently, for compliance sampling they collect composite samples from MBR #1 and grab samples from MBR #2. Stacy Ancel added that for DMR reporting for effluent parameters requiring 24-composite samples, they use only composite samples from MBR #1, which has the only working composite sampler. Required effluent grab samples are collected from one MBR train or the other on any given day. They usually alternate. Conduct sampling and analysis in frequency specified by permit? Yes. Are the correct effluent sample types (grab or composite) taken? Not currently, they cannot collect composite samples from MBR #2. If composite samples are required, are they flow proportioned (note permit allows time or volume flow proportioning)? flow proportioned. Are composite samples cooled to <4C to properly preserve them during the compositing period? Composite samplers are refrigerated. a) If the composite sample is cooled with ice or gel packs, do you measure the final composite sample temperature to make sure that the cooling is sufficient? Yes. b) Do you record these results? The facility does not keep logs of temperatures within each composite sampler. If a refrigerator is used for preserving composite samples, is there a thermometer in the refrigerator? Yes, and they maintain a temperature log. Are all grab samples cooled with ice, gel packs or refrigerated to <6 C from the time of collection until analysis including shipping time, if applicable? E.coli - 100ml sterile container, sample collected right from container. Samples are processed immediately so no need for cooling. Are all samples which require preservation properly preserved? Most samples analyzed immediately, so no need. Unless they are samples sent out to lab, then yes. Are pH and DO readings collected within 15 minutes of sample collection and is this documented? Samples are collected and analyzed in the on-site laboratory within 15 minutes. I commented about the consistent record of 0 E.coli/100ml for effluent samples. Stacy Ancel said they also consistently measure "0" E.coli/100ml before UV disinfection. I asked if they could collect an E.coli sample preMBR, just to confirm that their E.coli laboratory analysis procedures are able to detect E.coli. Stacy Ancel agreed to collect the sample and provide the results. 5 of 92 SAGANING WWTP Inspection Date: 08/25/2022 Unit: Interview/Operations and Maintenance Observation #: DM1-OB-005 Contains CBI: No Date: 08/25/2022 The Manager answered (in italics) the following O&M-related questions: Maintenance record system exists and include: a. As-built drawings - yes b. Shop drawings -yes c. Construction specifications- yes d. Maintenance history- daily log book. No other maintenance tracking. e. Repair history- also daily log book. Each MBR has a maintenance record. f. Records of equipment repair and timely return to service - no g. instruction files for operation and maintenance of each item of major equipment. Yes. h. Operation and maintenance manual is available? Other than manufacturers manuals, they are working on a comprehensive O&M plan. Does the facility have an adequate, qualified operating staff to carry out the operations at the facility? The Manager is the only certified wastewater operator (Class C&D, Michigan). The two other non-certified operators are trying to work on wastewater certificates. According to the Manager, they could use "2 or 3 more wastewater operators" to help stay on top of maintenance, recordkeeping, and reporting requirements. Operators conduct settleability tests 3x/week, and they need to get back to daily testing. They collect samples from mixed liquor after the MBR bio tank and filters. Any Bypasses over the last three years? No bypasses. Does the wastewater treatment facility have an alarm system for all essential equipment? Yes, they have a Sensaphone application that alerts operators if generator runs, influent is high level, or MBR is high level. Alarm capability will be upgraded with a new SCADA system (approx. 2023). Are alarms sent to qualified personnel who can respond immediately to remedy the problem? Yes, alarm sent in series and to all operators. Does the facility maintain written procedures for responding to emergencies such as power failures, floods, fires, and other natural disasters? Yes, follow an emergency plan. Is a logbook kept which documents all plant activities on a daily basis? Yes. Does the facility maintain an inventory of spare parts, either at the facility or close by, sufficient to keep all of its treatment units operational? Not currently, but working on it. Does the facility have standby power for all treatment units? ((40CFR122.41(e). Yes Is the standby power regularly exercised under load? ((40CFR122.41(e). Yes, monthly. Diesel generator. The Manager provided copies of the MBR Maintenance Procedure Plan, and the Saganing Water and Wastewater Improvements presentation (see Appendix 2, Inspection Documents).

Pages from Saganing Inspection_Records Received_OM Records.pdf Unit: Interview/Sanitary Sewer Overflows Observation #: DM1-OB-006 Contains CBI: No Date: 08/25/2022 I asked if there had been any backups or overflows in the sanitary sewer collection system, including pump stations, manholes and piping over the last three years? The Manager said that they have not experienced any backups or overflows in the collection system. Unit: Physical Inspection/Laboratory Observation #: DM1-OB-007 Contains CBI: No Date: 08/25/2022 We began the physical inspection of the Facility at 12:05 pm ET. We started in the laboratory. Stacy Ancel and Cory Berk represented the Facility to start the lab inspection. The Manager arrived shortly after we began. I asked Stacy Ancel to review the sample analysis procedures for E.coli, BOD, Ammonia, Phosphorus, pH, and TSS. Some observations are provided below: E.coli: I noted that one of the E.coli M-Coliblue 24 sample broths was expired (5/31/2019). Some of the MColiblue 24 sample broth packages were still within expiration dates. Facility representatives could not locate the written procedure currently used for E.coli analysis. I noted several instances where "dates received" and "dates opened" were left blank on opened laboratory chemical and standards containers. Before concluding the laboratory review, I asked for copies of the SOPs for Phosphorus and Ammonia-Nitrogen analyses (see Appendix 2, Inspection Documents). I also received copies of a lab equipment list and an analytical methods summary (see Appendix 2, Inspection Documents). Document(s): Saganing Inspection_Records Received_Lab SOPs_EquipList_Methods.pdf Unit: Physical Inspection/Headworks Observation #: DM1-OB-008 Contains CBI: No Date: 08/25/2022 The Manager led the tour of the wastewater plant, along with Cody Berk. We started at the influent wet well (see Photo Log image SAGA0100). The influent wet well has a basket/rag screen at the bottom of the rail (see Photo Log image SAGA0101). The Manager pointed out where the sludge decant flows returned to the influent wet well and noted that they estimate the amount of return flows and subtract from influent flow totals to avoid double counting of flows. We then entered the treatment plant building and stopped in the influent room to observe the influent flow meter (see Photo Log image SAGA0102) and ISCO influent composite sampler. I noted a thermometer in the ISCO sampler (see Photo Log image SAGA0103). Next we entered the fine screen room and observed the twin fine screen units (see Photo Log image SAGA0104). The Manager said the fine screens are working well. 7 of 92 SAGANING WWTP Inspection Date: 08/25/2022 Photo(s) 1. SAGA0101.JPG 2. SAGA0102.JPG 3. SAGA0103.JPG 4. SAGA0100.JPG 5. SAGA0104.JPG Unit: Physical Inspection/MBR Observation #: DM1-OB-009 Contains CBI: No Date: 08/25/2022 We observed the twin MBR units from the upstairs balcony (see Photo Log image SAGA0105). The Manager explained that flows go from the fine screens and split to each of the two MBR units, MBR #1 and MBR #2. Each MBR unit has three tanks (aerated anoxic 1, aerated anoxic 2, and aerobic). From the tanks, flows go to the MBR membrane units. Each MBR membrane unit consists of two tanks, each with four racks. Each rack has five filters. So each MBR membrane unit has a total of 40 membrane filters. The inside of one of the tanks is shown in Photo Log image SAGA0106. We walked down to floor level and observed the MBR control panel and screen (see Photo Log image SAGA0107). Last, I observed the composite sampler for MBR #2, which is currently out of service (see Photo Log image SAGA0108). The Manager showed us the port where they are currently collecting grab samples in lieu of composite samples for the MBR #2 treatment train. Photo(s) 1. SAGA0106.JPG 2. SAGA0107.JPG 3. SAGA0108.JPG 4. SAGA0105.JPG Unit: Physical Inspection/UV Observation #: DM1-OB-010 Contains CBI: No Date: 08/25/2022 I observed the ultraviolet light (UV) disinfection units for MBR #1 (see Photo Log image SAGA0109), and MBR #2 (see Photo Log image SAGA0110). Photo(s) 1. SAGA0110.JPG 2. SAGA0109.JPG Unit: Physical Inspection/Outfall Contains CBI: No Observation #: DM1-OB-011 Date: 08/25/2022 After viewing the UV systems, we left the building and headed to final outfall 001. First, we stopped at the manhole used to control the direction of treated flow to the ponds or the final outfall (see Photo Log image SAGA0111). At the time of the inspection, treated flows in the manhole were clear and were directed to the final outfall. We then walked to final outfall 001, where I observed a turbid discharge into the receiving water (see Photo Log image SAGA0112). The Manager attributed the turbidity to muskrat activity within outfall piping. 8 of 92 SAGANING WWTP Inspection Date: 08/25/2022 He said they will install a screen to keep muskrats from entering the outfall. Before leaving the outfall, I recorded the coordinates 4355'17"N; 8354'23"W. Photo(s) 1. SAGA0112.JPG 2. SAGA0111.JPG Unit: Physical Inspection/Chemical Room Observation #: DM1-OB-012 Contains CBI: No Date: 08/25/2022 We returned to the treatment building and viewed the Chemical Room. I observed the areas where MBR cleaning chemical are stored, including the sodium hypochlorite area (see Photo Log image SAGA0113), and 50% citric acid area (see Photo Log image SAGA0114). I also observed the aluminum sulfate storage area (see Photo Log image SAGA0115). Aluminum sulfate is used for phosphorus removal. I asked about the cleaning schedule for the MBR units. The Manager explained that each MBR is cleaned with chlorine once every two weeks, and with citric acid once a month. Photo(s) 1. SAGA0114.JPG 2. SAGA0115.JPG 3. SAGA0113.JPG Unit: Physical Inspection/Generator Observation #: DM1-OB-013 Contains CBI: No Date: 08/25/2022 I observed the diesel Caterpillar generator which provides backup power for the Facility (see Photo Log image SAGA0116).

The recommended wastewater treatment improvements presented in the study are as follows. SCIT Tribal Council and Tribal Administration has committed to developing these ftch recommendations. Ftch expects to complete the WWTP improvement design by 9-30-22. Finally, SCIT has an agreement with Kennedy Industries for headwork's pump replacement those improvements should be completed soon. Influent Pumping Station/Screen Building Provide an odor control system at the location of the onsite WBSA junction manhole. Install a new bar screen or influent chopper pumps to handle excessive solids and rags in the influent wastewater. Replace the combustible gas detection system in the Screen Building. Influent Equalization Construct a new 100,000-gallon above grade equalization tank. Fishbeck will consider steel versus concrete and present advantages of each alternative. MBR System Add a third EVOQUA Xpress membrane bioreactor (MBR) unit. Install overflow pipes on bioreactor tanks and route to equalization tank. Effluent Discharge and Disinfection System Install a new effluent sampler on common effluent discharge piping from all MBR systems. Install redundant ultraviolet (UV) disinfection units on each MBR system, or provide a centralized UV disinfection system with an appropriate level of redundancy. Biosolids Storage and Treatment Evaluate biosolids stabilization systems and current biosolids storage capacity. Design the selected biosolids stabilization system. Remote Monitoring System Provide a SCADA system to be able to remotely monitor and control lift stations. Upgrade the WWTP SCADA system to include remote monitoring and control capabilities, and an alarm callout system.

SCIT recently opened a 148-room hotel and signed an agreement with Standish Township to provide water and wastewater services to the nearby Whites Beach Service Area (WBSA). In July of 2020, a report was prepared entitled "Saga ning Casino Water and Wastewater Treatment System Evaluation" Fishbeck evaluated the existing water demands and I wastewater flows, estimated the impact of the future demand and flow associated with the Whites Beach Service Area, and then determined if the SCIT facilities could reliably handle the projected future water demand and wastewater flow ', J _____ Saganing WWTP Inspection Report Appendix 2 page 64 of 92 Background In 2018 the SCIT signed an agreement with Standish Township to provide potable water and wastewater treatment services to a defined area in the Township identified as the Whites Beach Service Area (WBSA). A 2016 Master Plan prepared by Rowe Engineering is the planning document that projected demands from the Casino and from the 240 acres adjacent to the casino that may be developed. Fishbeck has prepared drawings and specifications for Phase 1 improvements at the Water Wastewater Plant in Sagan ing. The project is out for bids currently. Fishbeck is also finishing a Scoping Study for a Phase 2 Expansion at the Saganing plant that will establish future treatment and facilities for the demands on the system over a 20-year planning period. Short Term Phase 1 Improvements are intended to cover a 4-year timeline. Fishbeck has prepared a Water System Evaluation Study which looked at the water system, future water system demands, and the location of a possible elevated storage tank. Fish beck will proceed with the design of the elevated storage tank upon authorization from the SCIT. Upon completion of the Scoping Phase Fishbeck will proceed with the design of the selected improvements and facilities for the Phase 2 improvements.

Filtered water is disinfected and stored in clear wells in the building until it is pumped out to the distribution system that services the casino, hotel, and tribal facilities. Medium and high flow pumps deliver treated water to the distribution system. S Pumps are running continuously to maintain pressure on the system, and a pressure sustaining valve vents water back into the clear wells if not needed in the system.

Test preparation Reagent storage pHlTemperature Before starting Storage temperature: 2-8 C (35-46 F) The pH of the water sample must be between pH 4-8. The temperature of the water sample and reagents must be between 20-23 C (68-73.4 F). In case of not working at the correct recommended temperature an incorrect resultrnay be obtained. Analyze the samples as soon as possible for best results. Time dependency: The final absorbance is reached after a reaction time of 15 minutes and then remains constant fora further 15 minutes. Review safety information and expiration date on the package. Review the Safety Data Sheets (MSDS/SDS) for the chemicals that are used. Use the recommended personal protective equipment. Dispose of reacted solutions according to local, state and federal regulations. Refer to the Safety Data Sheets for disposal information for unused reagents. Refer to the environmental, health and safety staff for your facility and/or local regulatory agencies for further disposal information. Procedure 1.

Interferences Interference level 1000 mg/L 500 mg/L 50 mg/L 25 mg/L 10 mg/L 5 mg/L 2 mg/L The ions listed in the table have been individually checked against the given concentrations and do not cause interference. The cumulative effects and the influence of other ions have not been determined. Primary amines are also determined and cause high-bias results. A 10,000-fold excess of urea does not interfere. All reducing agents interfere and cause low-bias results. A large excess of ammonium can cause result displays within the measuring range. It is advisable to carry out a plausibility check by making dilutions. The measurement results must be subjected to plausibility checks (dilute and/or spike the sample).

L[I1 Test preparation Reagent storage pH/Temperature Before starting Storage temperature: 15-25 C (59-77 F) The pH of the water sample must be between pH 2-10. The temperature of the water sample and reagents must be between 15-25 C (59-77 F). ATTENTION-Important information for the evaluation! Without hydrolysis, onlythe (dissolved) orthophosphate is measured. The result of the orthophosphate measurement can be expressed as: mg/L P04-P (for example,process,analysis), mg/L P04 (for example, drinking water or boiler water analysis), mg/L P205 (for example, soil analysis). With hydrolysis, all of the phosphorus (Total-P, Ptotal) is measured. The result of the total phosphorus measurement can be expressed as: mg/L Ptot = Display mg/L P04-P (for example,for monitoring threshold values in wastewater), mg/L P04 (for example, drinking water or boiler water analysis), mg/L P205 (for example, soil analysis). Inverting the vial after hydrolysis improves the reliability of the result.
