It has been found appropriate to diange the Radiological Environnental Honitoring Section of the im', Al RETS by the incorporation of a number of sections of the Radiological Assessment Branch Technical Position, Revision 1, Novo-ber 1979.

These interim changes will be included in the next revision of NUREG-0472 and flVREG-0473.

The changes, as recorded on the enclosed sheets, should be used as guidance for the present and future RETs reviews for both ors and OLs.

l 3/4.12.1 MONITORING PROGRAM The radiological environmental monitoring program required by this specification provides representative measurements of radiation _and of radio- l

' active materials in those exposurt pathways and for those radionuclides that

lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix ! to 10 CFR Part 50 and thereby supplements the i radiological affluent monitoring program by verifying that the measurable

} concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of-the environmental exposure pathways. The initially specified monitoring program will be effective for at least the first three years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The required detection capabilities for environmental sample analyses are-tabulated in terms of the lower limits of detection (LL0s). The LL0s required by Table 4.12-1 are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLO is defined as an a priori (before the fact) limit representing the capa-bility of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement, Detailed discussion of the LLO, and other detection limits, can he found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L. A.. " Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry" Anal. Chem. 40, 586-93 (1968), and Hartwell, J.
