survey report in support of a ' requesti for. a - confirmatory -

survey of afgroup of laboratories in GA's: Building 2? (Ref~

v 1).

That group of science laboratories was referredEto as-

" Group 3."

Subsequent;to that request,1GA< requested that three additional laboratory rooms and-'an affected office'in Building 2 be added to " Group 3."

'The affected! office was included.because a trench had to.be dug in'itsifloor to

~

remove an underground drain line.

In support of:this'later-request,oGA. transmitted to your office, by FAX, a brieff description of'the areas to be added.and some-associated survey.information.

The' Group 3 areas, including.theiadded rooms and affected' office, were surveyed by the Oak Ridge-Associated Universities' EnvironmentalLSurvey'and~ Site' Assessment ~ Team-(ORAU) during'their visit'to GA's site-March 114-23,-1989.

and rooms-1 and-2 of-lab 309)1and the affected: office (room
