SUBJECT:
ENVIR0TENTAL REVIEW OF LICENSEE'S AMEt'D"ENT APPLICATION DATED FEBRUARY 28, 1980
- s I.
Background
On January 28, 1980 an order was issued to Combustion Engineering, Inc.
(CE) which modified its Materials License No. SNM-1067 to assure compliance with 40 CFR 190. The order specified that CE shall take action if the radio-active contaminants in the gaseous effluents exceed 3 pCi per calendar quarter.
This action level was based on the CE semiannual effluent release reports for the past few years.
CE was not notifled in advance of this action level.
After receiving and evaluating the order, CE found the action level was below its current release rate.
CE notified the staff informally that the gaseous
=:~
effluent releases reported over the past few years were left because the stack effluent samples taken were not representative.
A new sampling system was installed in 1978 and samples taken since January 1979 indicated larger gaseous efflue';ts than previously reported. Accordingly, by letter dated February 28, 1980, CE requested the Commission to increase the action level fron 3 pCi per calendar quarter to a level more consistent with its current emissions as measured from January 1979 through January 1980.

Discussion

+
In the January 28, 1980 order, the staff set an action level for gaseous effluents at 3 pC1 per quarter, which was approximately equal to CE's reported se tiannual release rate. This action level is equivalent to less than 0.2%
of the EPA's 25 mrem /yr. standard spect fied in 40 CFR 190.
Data submitted by CE in their February 28, 1980 request indicates that the 3.w.u average emission level for calendar year 1979 was approxicately 33pC1. Based on these new. data, the staff proposes an action level of 18 pCi per calendar quarter which would result in a lung dose to a critical individual at the
