Does anyone know of a specific NRC or DOE reg that prohibits this?
The site I am currently contracted at has double posting all over the place, and in one instance even has triple posting (a boundary fence, an temporary fence inside that, then a storage building inside that--each posted as an RMA and radiation area). Their explanation is basically: "You can't be docked for too much posting, only insufficient posting".
The site is NRC-licensed, but is also audited by the DOE due to WIPP-designated waste packaging and shipments. The NRC auditor has been here once since I started 4 months ago, and the DOE auditors are coming in 6 weeks for my project. (The triple-posted area is part of the DOE work under my contract.) The site has been around for fifty years, so maybe it's just "let it be as it always has been".
Thanks in advance for any info.
