O ATTACHMENT II Reporting Recuirements Environmental Radiological Monitoring 1.
Results for all sacples taken shall be reported to the Commission twice a year-within 60 calendar days cf January 1 and July 1.
The data shall be summarized on a quarterly basis, following the format of Table I.
In the event that some results are not available within the 60 day period, the report should be submitted noting and explain-ing the reasons for the missing results. The missing data shall be submitted in a supplementary report as soon as possible.
2.
If levels of radioactive materials in environmental media indicate that the resultant dose to an individual from these levels could equal or exceed 10 mrem /yr, estimates of the resultant doses to individuals and critical population groups, and the assumptions upon which the estimates are based shall be provided.
If levels of radioactivity in an environmental medium sample indicate that the resultant dose to an individual from these levels could equal or exceed 40 mrem /yr, a report will be made to the appropriate Connis-sion Regulatory Operations Office within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by telephone or telegraph, and a plan will be submitted within one week to determine the cause of the elevated levels and to reduce the doses to the design objective. For example, if individual charcoal filters show I-131 con-centrations in air of 2.6 x 10 12 pCi/cm3 3
(2.6 pCi/m ) or greater (1.1 x 10-14 pCi/cm3 if the milk pathway is involved), or if indi-vidual milk samples show I-131 concentrations of 6 x 10-9 pC1/cm3 (6 pCi/1) or grea;er, the results will be reported within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />

along with a plan to determine the cause of and to reduce these levels submitted as above.
3.
If samples of environmental media collected over a calendar quarter show total levels of radioactivity that could result in accumulated doses to an individual of 2.5 mrem for that quarter, the results shall be reported and a plan submitted and implemented within 30 days to limit conditions so that the annual dose to an individual will not exceed the design objective.

m
< If samples of environmental media collected over any two calendar quarters show total levels of radioactivity that would result in accumulated doses to an individual of 3.8 mrem in those two quarters, the results shall be reported and a plan submitted and implemented within 30 days to limit conditions so that the annual dose to an individual will not exceed the design objective.
4.
If such levels as discussed in (2) and (3) can be definitely shown to result from sources other than the licensed plant (e.g., from testing of nuclear devices) by similar concentrations found in
" background samples" - i.e., samples that could not be affected by emissions from the licensed plant, this reporting action need not be taken. J1stification for assigning high levels of radioactivity to sources other than the Crystal River plant must be provided in the report.
5.
If statistically significant variations of off-site environmental radionuclide concentrations with time are observed, a comparison of these results with effluent releases shall be provided.
6.
Individual samples which show higher than normal levels (25% above background for external dose, or twice background for radionuclide content) should be noted in the reports.
