The Facility is currently in temporary closure. The Environmental Protection Agency's Facility records indicate that the Facility has two 1,000-gallon, cathodically protected steel underground storage tanks(USTs) installed in 1998. Records indicate that the piping is safe suction and constructed of fiberglass reinforced plastic (FRP). Inspection Narrative On June 10, 2025, the EPA conducted an inspection at Former Azure Store 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 attempted to speak with the owner and sent an email on May 16, 2025, to schedule the inspection and provide inspection details (see Attachment A). The EPA inspector arrived at the Facility at 8:15 a.m. CDT and was met by the Facility owner. The EPA inspector introduced herself and presented inspector credentials. The Facility owner consented to the inspection. The EPA inspector conducted a physical inspection of the UST system as well as a review of Facility records. Photographs of UST system components taken during the inspection are in Attachment C. Tank Leak Detection Tank leak detection is not being conducted. The owner was informed that the USTs should be monitored weekly, using the manual tank gauging method for release detection, or be emptied. Piping Leak Detection The system piping is safe-suction, therefore piping leak detection is not required. Cathodic Protection According to EPA records, both tanks are single-walled STI-P3 tanks with FRP piping. The last galvanic cathodic protection system evaluation was performed on July 29, 2021, and should have been retested by August 2024. 3050005 Former Azure Store Page 1 of 2 6/10/2025 UST Inspection Periodic Testing/Inspection of Spill and Overfill Prevention Equipment Triennial testing records of spill buckets and overfill prevention devices (flapper valves) are not required while the system is in temporary closure.

The EPA observed a certificate of registration for the fund onsite. Physical Observations The EPA inspector viewed the spill buckets and fill ports. The spill buckets were clean and the fill ports securely locked. The EPA inspector measured liquid levels in each UST. The west tank had approximately 12 inches of liquid, which is equivalent to 140 gallons. The east tank had approximately two (2) inches of liquid, which is equivalent to 14 gallons. The EPA inspector explained how manual tank gauging could be performed. The owner indicated that he intended to remove the fuel.
