AGREEMENT STATE REPORT - DAMAGED GAUGE
The following information was provided by the Oklahoma Department of Environmental Quality via email:
"The Oklahoma Department of Environmental Quality (DEQ) received a report from Kleinfelder, Inc. that a nuclear gauge [incident] occurred on November 4, 2025, at approximately [1430 CST] at the Atoka Pump Station Vault Pit Excavation Site.
"During site operations, a Kleinfelder vehicle struck a Humboldt nuclear gauge (serial number: 3753) when moving the vehicle to avoid a collision with an on-site excavator. At the time, the gauge was positioned behind the vehicle. The impact caused the source rod to break while in the retracted position.
"Immediate safety protocols were enacted as follows:
"The vehicle was left in place.
"All personnel were evacuated from the area.
"A 15-foot perimeter was established around the source using caution tape.
"Radiation survey meter readings were completed at the four cardinal points surrounding the portable nuclear gauge.
"At the truck perimeter: 0.00 mR/hr
"After the truck was moved (approximately 3 feet from the source): 0.02 mR/hr
"The gauge and broken source rod (in the retracted position) have been safely packed into the transport case and are currently stored [at a location in Oklahoma City].
"In accordance with regulatory requirements, the incident was reported to the Oklahoma DEQ via their Incident Line (1-800-522-0206) at [1753 CST] on November 4, 2025.
"A leak test was conducted on November 5, 2025, and is currently being processed."
