The total tritiwa .4 ease for this reporting period was 1.52E+02 curies.
This included 1 51E+02 curies in processed radioactive waste and primary coolant system letdown, 3.50E-02 curies in Unit 1 steam generator blowdown, 9.58E-01 curien in Unit 2 steam generator blowdown, and 7.55E-02 curies in tne retention pond.
I All r:'dioactiva liquid releases to Lake Michigan were made through the ciredating water discharge system.

9.0 MISCELLANEOUS REPORTING REQUIREMENTS 9.1 Revisions to the PBNP Offsite Dose Calculation Manual (ODCM) and Process Control Program (PCP)
No revisions were made to the PCP during this reporting period.
However, changes were made to the ODCM with the addition of a new section. The new revisions cannot effectively be identified in the Semiannual Report. A complete copy of the ODCH will be forwarded to the Nuclear Regulatory Commission.
f 9.2 Interlaboratory Comparison Program The analytical laboratory contracted to perform the radioanalyses of PBNP environmental samples participated in the EPA Interlaboratory Comparison Program during this reporting period.
9.3 Deviations from Specified Environmental Sample Types, Locations, and Frequencies Two deviations from sampling types, frequencies, and locations specified in Technical Specification 15.7.7 occurred during this reporting period. One air particulate filter was lost in the field due to environmental conditions and a lake water sample was unavailable because of the lake ice.
y.4 Summary of Unachievable Specified Environmental LLDs LLDs listed in Table 15.7.7-2 of the PBNP Technical Specifications were accomplished for all samples during this reporting period.
9.5 Special Circumstances No special circumstances report regarding operation of the explosive gas monitor for the waste gas holdup system were needed during this reporting period.
