EN Revision Text: OFFSITE NOTIFICATION DUE TO PCB OIL SPILL
"At 1515 EST on 11/10/21, approximately 89 gallons of PCB oil is unaccounted for from the Substation 'N' Transformer, located in the Owner Controlled Area. Transformer nameplate oil capacity is 569 gallons. Prior to removal of the original Substation 'N' Transformer, approximately 475 gallons of 10-CA-OIL (PCB Oil) was evacuated and stored by HEPACO (a licensee vendor). Approximately 5 gallons of oil is inaccessible to evacuate and remains in the original transformer. Below the transformer was evidence of oil leakage to the ground. The leakage appears to have been occurring over time, not as a result of a catastrophic failure. This condition is reportable to the Virginia Department of Environmental Quality (VA DEQ). The VA DEQ was notified of this condition at 1815 on 11/10/21. Cleanup activities are on-going.
"This event is reportable in accordance with 10CFR50.72(b)(2)(xi) for 'Any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an on-site fatality or inadvertent release of radioactively contaminated materials.'"
The licensee will be notifying the Louisa County administrator and has notified the NRC Resident Inspector.
* * * UPDATE FROM MARC HOFMANN TO DONALD NORWOOD AT 1309 EST ON 11/12/2021 * * *
"Initial, unofficial, field testing performed by HEPACO indicated the oil released to the ground was PCB-Contaminated Oil. The official test results from the lab indicated that the oil is in fact not classified as PCB-Contaminated Oil. Therefore, this update is being made to EN55570 to clarify that the oil released to the environment was not PCB-Contaminated Oil."
The licensee notified the NRC Resident Inspector and the VA DEQ of this update.

EN Revision Text: AGREEMENT STATE REPORT - STUCK SHUTTER
The following was received from the state of Illinois (the Agency) via email:
"The Agency was notified by British Petroleum [BP] (registered as a general licensee under the name CHICAP Pipe Line Company (9152422)), that they had discovered a stuck shutter on a generally licensed fixed gauge at their Lemont, IL location. The shutter, which is normally open, has apparently been broken for many years and was only discovered during removal last week. No personnel exposures resulted and the gauge has been secured pending disposal.
"A specifically licensed service provider was removing a generally licensed fixed gauge on 11/10/21 for planned disposal through a waste broker when it was discovered to have an inoperable shutter. The gauge was a Ronan Engineering Company model SA-1, containing 50 milliCi of Cs-137 (s/n 8333GG). While the shutter was reportedly routinely tested, the arm that moves the shutter was severely corroded. It was only during removal that the registrant discovered the shutter itself was broken. The gauge has been in service for 24 years and was installed at a 12' height with the beam projecting into the process equipment. As the shutter remains in the open position and personnel are not in the beam path, personnel exposure is not a concern. No reported exposures during removal. The gauge has been double locked with the beam facing down into the concrete floor. The shutter is being repaired so it may be properly transported and disposed of through Bionomics (waste broker). A written report detailing remedial action is required within 30 days under 32 Ill. Adm. Code 330.220(a)(3)(E).
"This incident is reportable under 32 Ill. Adm. Code 340.1220. At this time, it does not appear a response to the site by Agency staff will be required. BP's consultant indicated that the gauge manufacturer reports 3-4 of these gauges per year are returned. The issue is reportedly a seal that leaks and gives rise to corrosion - despite being used within the environmental conditions specified in the SSDR [Seal Source Device Registry]. This information is anecdotal but included for NRC's evaluation and trending analysis. This matter will remain open until confirmation of shipping for disposal is received."
