and Particulates (Enclosure 1).

Celi "anagcment meeting of May 23, 1979.
2.
'G e n reporting analytical data for HPR and AM1-5 samples, both the activity of the radionuclides identified on the charcoal filter and the particulate filter will be reported separately on the data sheet.
3.
RMC will count the filter paper for gross beta.
RMC will retain the results and identify by both TMI and sample coodinator's numbers.

2.
Per agrcc=ent with Ms.
M. Reilly, PA, BRH it is permissible to discharge sewage without prior approval of SRH provi g the concentration is less than 3E -8 Ci/al which is 0.1 (MPC)w for I for unrestricted areas.
least lE -11 3.
For HPR and AM l-5 charcoals say.ge we need on MDL or at p<i/cc which is 0.1 (MPC)a for I for unrestricted areas.
s 4.
For HPR and AM l-5 filter paper sa ples we need an MDL of at least SE 1" cri/cc for particulate gross beta a -tivity.
5 Then this should go through PORC for a rev sion to appropriate TMI SOP's.
