EN Revision Text: AGREEMENT STATE REPORT - DAMAGED PORTABLE GAUGE

The following information was provided by the Maryland Department of Environment via email:

"On August 24, 2022, at about 1840 EDT the Maryland Department of the Environment Radiological Health Program (MDE/RHP) was contacted via telephone from the Emergency Response Department (ERD) staff that the ECS Mid-Atlantic, LLC, Troxler nuclear moisture/density gauge was run over and damaged by an excavator in the project jobsite at the Grosvenor-Strathmore Metro Station project. MDE/RHP inspector immediately called and contacted the RSO of the licensee and preliminary information about the accident and measures taken. The MDE/RHP inspection team responded on August 25, 2022 and August 26, 2022 went to the licensee office and conducted investigations.

"On the day of the accident, at about 1503 EDT the Technician moved the gauge to the side, on the curb beside the trench, and the excavator operator that moved the arm (bucket) down the trench hit the gauge. The source rod of the gauge was in its safe (parking) position and the top of the gauge was damaged. The Troxler gauge is Model 3440, with device serial number 31969 which contain Cesium - 137 sealed source with estimated nominal activities of 8 milliCuries, and Am-241:Be with estimated nominal activities of 44 milliCuries.

"The gauge was later locked and put into the transportation case and the technician took it to the ECS Mid-Atlantic. Surveys conducted at the surfaces of the gauge are normal; and leak test results are expected. The case has been reported to the Nuclear Material Events Database (NMED) on 8/26/2022."
