L-RAB William H. Regan, Jr., Chief Environmental Projects Branch M L MONTICELLO ENVIR0tNENTAL RADIOLOGICAL MONITORING PROGRAM F. Congel, RA-L, has reviewed the changes in the Radiological Environmental Monitoring Technical Specifications submitted by the Northern States Power Comany for the Monticello Plant. The proposed changes are an igrovement over the original specifications and should be accepted as submitted.
You also requested in your memo of December 26, 1973, that the specifications be reviewed to ensum consistency with applicable guidelines for the pending FTOL. Although no guidelines regarding technical specifications for FTOL's have yet been approved, the latest Appendix I draft states that all light water cooled reactors must consonn with the latest emission requirements within twenty-four months after formal issuance of the doctment.
Since the augmented radwaste system for Monticello is due for cogletion by Summer, it l
would appear that their tecntical specifications could now be rewritten in the fonnat used for new OL's add iglemented by Fall. Thus, the proposed technical specifications should be modified by the applicant to include the reporting requirements msulting from the iglementation of Appendix I.
An exagle of these reporting requirements is attached.
I It is assined that ETSB-L will also require similarly revised effluent monitorigg technical specifications.

j 1.
The semi-annual report, specified in Section 5, shall contain:
.c a.
A narrative summary of the results of off-site airborne environmental surveys performed during the report period.

b.
For each medium sampled during the year, a list of the 3
sampling locations, the total number of samples, and the f
highest, lowest, and the average concentrations for 'the
'l highest location.

2.
In the event that some results are not available within the i
4 60 day period, the report should be submitted noting and explain-
.j ing the reasons for the missing results.
The missing data shall be submitted as soon as possible in a supplementary report.
d 3.
If statistically significant variations of offsite environmental
!j radionuclide concentrations with time are observed, a comparison
'k of these results with effluent releases shall be provided.
4.
Individual samples which show higher than normal _ levels (25%
}
above background for external dose, or twice background for l
radionuclide content) will be noted in the report.
