Inspection Narrative and Site Description
1.0 Introduction
The inspection was conducted at the City of Belcourt wastewater treatment facility (facility; WWTF) located in Rolette County, North Dakota, to evaluate compliance with the facility's National Pollutant Discharge Elimination System (NPDES) permit. The EPA is responsible for implementing the NPDES program in Indian Country within the State of North Dakota. The inspection was announced approximately one month prior to the inspection to coordinate logistics for the inspection.
On the morning of August 22, 2023, U.S Environmental Protection Agency (EPA) inspectors Brit Rustad and Akash Johnson (collectively, "we") met with Turtle Mountain Public Utilities Commission (TMPUC) representatives Kenny Azure, Director, and with Harold Bruce and Eric Thomas, Operators. We were also joined by Indian Health Service (IHS) representative Tyler Timmons, Tribal Utility Consultant. We presented our credentials and had an opening conference in the TMPUC office where we explained the purpose of the inspection and discussed the design, operation, and CWA and NPDES compliance of multiple WWTFs operated by the TMPUC, including the subject facility. After the opening conference, we proceeded to conduct site reviews of the WWTFs operating by the TMPUC, including the subject facility, for the remainder of August 22, 2023 and part of August 23, 2023. Throughout the inspection, we noted our observations in bound checklists. Photographs taken during the inspection are included in the attached photo log.
2.0 TMPUC Operations
During the opening conference when discussing all facilities, representatives indicated that daily checks on all lift stations are performed but that lagoon cells were not inspected on at least a weekly basis. They also stated that weekly inspection logs are not being kept. Facility representatives stated that some grease accumulation had been noted in the collection system and that the suspected source was the hospital. On a call that occurred on November 8, 2023, Harold Bruce indicated that a sanitary sewer overflow (SSO) had occurred several days prior from a junction box in the collection system. Further information related to this can be found in the findings, corrective actions and recommendations section, under finding #7. Lastly, there has not been any sludge removal or depth testing done recently at any of the lagoons operated by TMPUC.
The TMPUC operates a regional water treatment plant and distribution system which provides water to multiple communities and users across the region. At the time of the inspection, the TMPUC employed eight operators and various managerial and administrative support staff. The majority of TMPUC operations are dedicated to the provision of potable water, but all operators perform both water and wastewater duties as needed.
TMPUC customers, rates, and finances were briefly discussed during the opening conference. Water and wastewater fees were collected separately, and different flat fees were assessed for regular residential, Tribal elder residential, and commercial users. Kenny indicated a portion of TMPUC's annual budget was subsidized by federal and/or Tribal sources.

3.0 Facility Description and Site Review
The facility is permitted as a discharge facility, under the EPA Region 8 Lagoon General Permit (Permit) for North Dakota. According to the Notice of Intent (NOI) for Permit coverage:
x The facility serves a community of roughly 2,702 people, as well as food service establishments, gas stations, car washes, the hospital, dental facility and retirement home.
x The average design flow to the facility is 0.202 million gallons per day (MGD) and the peak design flow is 0.253 MGD.
x The average design organic treatment capacity is 318 lbs BOD5 per day and the peak design organic treatment capacity is 397 lbs BOD5 per day.
x The facility is a five-cell lagoon system. The table below has the operating volume for all five cells as indicated in the NOI.
Cell ID Cell 1 Cell 2 Cell 3 Cell 4 Cell 5 Total
Area (acres) 3.0 3.0 4.6 6.27 6.27 23.14
Operating Volume (MG) 4.9 4.9 7.5 10.2 10.2 37.7
Between the opening conference and inspection of the subject facility, we inspected several other WWTFs operated by the TMPUC. The facility includes two lift stations, the "South Cluster" lift station, located in the collection system, and the "Lagoon" lift station, which pumped wastewater from cell 3 to cell 4 of the lagoon. Before arriving at the lagoon, we inspected the South Cluster lift station. Only one pump, #2, was operational/ installed at the time of the inspection and the seal fail light was illuminated for that pump (photo 456). When we arrived at the lagoon the gate was closed and locked. We proceeded to drive and walk around the interior of the lagoon enclosure to evaluate berm integrity and general conditions of the cells. Vegetation and cattails had reached a height greater than six inches in several areas, specifically around cells 1-3 where the berm was too close to the perimeter for the mowing tractor to access. We proceeded to inspect the Belcourt Lagoon lift station which is situated between cells 1-3 and 4-5. Only one pump was installed/ operational at the time of the inspection.
At the end of our inspections on August 23, 2023, we held a brief closing conference with Eric Thomas, Harold Bruce and Tyler Timmons where preliminary findings were discussed. Later in the day on August 23, 2023, the EPA sent an email to Kenny Azure with the preliminary findings from the inspection and some resources for using NetDMR.
Findings, Corrective Actions and Recommendations
Finding #1: Weekly lagoon inspections were not being conducted. Weekly lagoon inspections were not being conducted.
