On August 29, 1979 E. Shum and T. Decker of flRC, and Dr. D. Kalkwarf, flP.C consultant from Bf UL, met with the staff of Allied Chemical at the Allied Chemical Plant at tietropolis, Illinois, (Allied Chemical attendees:
R. liewman, A. Riley, R. Yates and J. Thomas) to discuss the procedure for the establishment of a monitoring program to demonstrate future compliance with the nuclear fuel cycle environmental standards as specified in 40 CFR Part 190. Allied Chemical (the licensee) proposed to collect environ =
mental air samples at sampling station flo.11 which is near the closest resident to the plant and to analyze the sample for uranium solubility clas-sification following the method established by BriWL., The licensee has already set up environmental air sampling stations around the plant site to collect air samples continuously to analyze them for uranium concen-trations in air. The result of the licensee's analysis of uranium solub'lity classification in the air sample will provide flRC with preliminary data to complete the radiological impact assessment due to radiological releases from routine plant operation.
In order to provide confirmatory information on the solubility classification in the collected air sample, flRC has contracted BilWL, under the direction of Dr. D. Kalkwarf, to conduct a similar study.
It was agreed that the BilWL will bring in their pumping equipment to collect independent air samples at station flo.11 and it is expected that the sampling period will be about two weeks dependir. on the weather conditions. The samples will be split between Allied Chemical and BriUL for solubility analyses.
If the results agree between both partici, Allied Chemical will conduct their own sampling and analysis in the future.
If the results disagree, Allied Chemical will have to resolve the technical differences between their analytical technique and BilWL's.
To do this Allied Chemical will have to provide additional split air samples to Bf4WL for further confirmatory analysis.
It is expected that the BilWL air sampling will be started in mid-September and the first comparative results from Bilill. and Allied Chemical will be available about two months after the completion of air sampling by BilWL.

The NRC staff and consultant also toured the plant, the environmental air monitoring stations and inspected the site cavironment at the nearest residence.
