RE: Grease Release

[glen.vickers@EXELONCORP.COM]

Dave,



We would analyze grease with the liquid LLD's.  We leaned to the

conservative side on this issue.  Sampling a drum of grease might not be the

easiest, but we certainly fill up the marinelli container for counting just

like a can of Crisco.  How large are the drums you're sampling?  We keep

minimum volumes of grease in the RPA and in the end minimize the amount of

sampling.  



If we have a tube of grease that is too small to achieve the appropriate

LLD's, then we would perform a qualitative analysis with a Ge counter (~10

min) in addition to a survey of the external surfaces of the tube.  Be

careful about combining small volumes of different materials into a larger

volume, you might create something that you can't get rid of later on the

EPA side of the house.
