The fuel at this Facility is sold to the public. The Environmental Protection Agency's Facility records indicate that the Facility has two fiberglass reinforced plastic (FRP) underground storage tanks (USTs) installed in 1994. Tank 1 has capacity of 15,000 gallons for regular unleaded fuel. Tank 2 has a capacity of 12,000 gallons for premium unleaded fuel. Records indicate that the piping is pressurized and constructed of flexible plastic materials. The USTs are currently in temporary closure while the owners upgrade the convenience store. Inspection Narrative On June 10, 2025, the EPA conducted an inspection at Utter Stop in Belcourt, North Dakota. The EPA last inspected the Facility on May 16, 2023, and it was selected for routine re-inspection. The EPA inspector spoke with the Facility representative and sent a follow-up email on May 15, 2025, to schedule the inspection and provide inspection details (see Attachment A). The EPA inspector arrived at the Facility at 9:25 a.m. CDT and was met by the Facility representative. The EPA inspector introduced herself and presented inspector credentials. The Facility representative consented to the inspection. The EPA inspector conducted a physical inspection of the UST system as 3050005 Utter Stop Page 1 of 3 6/10/2025 UST Inspection well as a review of Facility records. Photographs of UST system components taken during the inspection are in Attachment D. Copies of operation and maintenance records are in Attachment B. Tank Leak Detection Tank leak detection equipment consists of an automatic tank gauge (ATG), which conducts monthly static tests. The EPA was provided 8 months of passing release detection monitoring for the USTs. The Facility representative explained that a new leasee had been in place for most of the past year who was not maintaining the property or the fuel system properly. The USTs still contain fuel but have not been operating since January 2025. The owner is planning on finding new tenants and will have the required testing of the system performed prior to selling fuel again. No record of an annual test of the ATG system was present at the time of the inspection, but the Facility representative stated that testing was scheduled for the last week of June. Piping Leak Detection The piping does not currently contain any fuel. Annual testing of the line leak detectors and line tightness was scheduled for the last week of June 2025. Records from the testing were still pending at the time of this report. Cathodic Protection The UST system is a non-corrosive material, and therefore, cathodic protection testing is not required. Periodic Testing/Inspection of Spill and Overfill Prevention Equipment Triennial testing records of spill buckets was provided via email prior to the inspection. The spill buckets were tested on May 8, 2024. Tank 2 (Premium) spill bucket failed the test and is scheduled for replacement in June 2025. According to EPA records, the overfill prevention (high level alarm) was last tested in October 2022 and passed. The operator had a quote to install flapper valves in each tank. EPA noted that the high-level alarm can be used for overfill prevention but should be re-tested before October 2025. Periodic Operation & Maintenance (O&M) Walkthrough Inspections Records of monthly and annual walkthrough inspections for the last twelve months were provided at the time of inspection. The EPA noted that the monthly walkthrough inspections were blank for release detection records since January 2025. The leasee (temporary operator) did not maintain these properly and no longer operates the Facility. Operator Training A certificate for Class A and B operator training was maintained onsite at the time of inspection. The operator stated that all new operators will be trained when they re-open for fuel sales in July 2025. Financial Responsibility The Facility uses the North Dakota Department of Environmental Quality Petroleum Tank Release Compensation Fund (fund) for financial responsibility coverage. The EPA observed a certificate of registration (Number 1306) for the fund onsite. 3050005 Utter Stop Page 2 of 3 6/10/2025 UST Inspection Physical Observations The EPA inspector viewed the spill buckets, tank top sumps, fill ports, lines, and dispensers. The spill buckets appeared clean. The premium spill bucket was loose. There was an exterior annunciator for the overfill alarm, but there was no test button to confirm the sound. Inspection Conclusions and Recommendations At the end of the inspection, Ms. Person filled out an Onsite Deficiency Identification Form (see Attachment C). Prior to departing the Facility, Ms. Person stated that a full inspection report would be forthcoming, which includes the inspection checklist (see Attachment D). Inspection Report Attachments A.
