1.0 RADIOACTIVE LIQUID RELEASES The total radioactive liquid release excluding tritium for this reporting period was 1.53E-01 curies. This included 3.37E-02 curies in processed radioactive waste and primary coolant system letdown, 2.07E-02 curies in Unit 1 steam generator blowdown, 9.86E-02 curies in Unit 2 steam generator blowdown, and 5.16E-05 curies in sewage sludge. There was no detectable activity in the retention pond effluent other than tritium.
The total tritium release for this reporting period was 4.22E+02 curies.
This included 4.21E+02 curies in processed radioactive waste and primary coolant system letdown, 3.02E-02 curies in Unit 1 steam generator blowdown, 5.13E-01 curies in Unit 2 steam generator blowdown, and 1.49E-02 curies in the retention pond effluent.
All radioactive liquid releases to Lake Michigan were made through the circulating water discharge system.
1.1 Circulatina Water Radionuclide Release Summary 1.1.1 Releases During Current Reporting Period Radioactive liquid releases via the circulating water discharge are summarized by individual source, total, and equivalent curie release on a monthly basis and presented in Table 1-1.
1.1.2 Additions to Previous Semiannual Monitoring Report The following information was not available at the time of previous report preparation and should be added to Table 1-1 of the Semiannual Monitoring Report for January 1,1986 through June 30, 1986.

6.0 NON-RADI0 ACTIVE CHEMICAL RELEASES 6.1 Scheduled Chemical Waste Releases
- Scheduled chemical waste releases to the circulating water system from July 1, 1986 to December 31, 1986 included 4.06E+06 gallons of neutralized wastewater. The wastewater contained 5.27E+02 pounds of suspended solids and 4.81E+05 pounds of dissolved solids.
- Scheduled chemical waste releases are based on each neutralizing tank analysis.
6.2 Miscellaneous Chemical Waste Releases
- Miscellaneous chemical waste releases from the retention pond and the sewage plant to the circulating water for July 1,1986 to December 31, 1986, included 1.37E+07 gallons of clear wastewater.
The wastewater contained 6.32E+02 pounds of suspended solids and 6.26E+04 pounds of dissolved solids.
- Miscellaneous chemical waste releases are based on retention pond and sewage plant effluent analysis from July 1,1986 to December 31, 1986.

O 9.0 MISCELLANE0US REPORTING REQUIREMENTS 9.1 Revisions to the PBNP Offsite Dose Calculation Manual (00CM) and Process Control Program (PCP)
No revisions were made to either the ODCM or PCP during this reporting period.
9.2 Interlaboratory Comparison Program The analytical laboratory contracted to perform the radioanalyses of PBNP environmental samples participated in the EPA Interlabora-tory Comparison Program during this reporting period.
9.3 Deviations from Specified Environmental Sample Types, Locations, and Frequencies Deviations from sampling types, frequencies, and locations specified in Technical Specification 15.7.7 occurred during this reporting period. These deviations were as follows:
- 1. On three different occasions power was lost to the air sampler located at sampling station E-08 resulting in a deviation from the requirement to continuously collect the air sample. Plans and arrangements to relocate this sta-tion to a site with a more reliable power source were formulated following the occurrence of the second power loss.
- 2. A fire occurred at sampling station E-08 resulting in the loss of the air sample and the TLD located at this station.
A temporary sampling station was established immediately at this location to permit the continued collection of samples. The loss of the station expedited our plan to relocate the station to a more reliable power source. A permanent replacement site for station E-08 has been established 0.4 miles north of the fire-destroyed location.
9.4 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.

- 10. ERRATUM TO PREVIOUS SEMIANNUAL MONITORING REPORTS The following correction should be made to Section 5 of the Semiannual Monitoring Report for the period of January 1,1986 through June 30, 1986.
Line 2 of page 13 erroneously indicated that the summarized environ-mental monitoring was conducted from July 1,1985 through December 31, 1985. .The dates should be changed to indicate that monitoring was conducted from January 1,1986 through June 30, 1986.
