Appendix B, Section 2.6.2.D:
Add footnote to read; The last sentence in specification 2.6.2.D is replaced by the following paragraph during the period June 6, 1981 through June 30, 1981; "If these monitors are inoperable for a period exceeding 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, tank discharges may be continued up to 14 days provided that discharges are collected in a retention basin. The mixed retention basin will be sampled and analyzed.
Retention basin valving will be verified to prevent further addi-tions to the basin and diluted discharges from the retention basin will be sampled and analyzed every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> during release.
Review of the above sampling technique does not increase the proba-bility of an unmonitored radiological release to the environment.
The sampling and valving will provide additional serification and confidence that 10 CFR 20 concentrations are noi. exceeded.
