2.0 RADIOACTIVE AIRBORNE RELEASES Radioactive airborne releases during normal plant operation are reported by total release in Table 2-1, and sumh.arized by isotope in Table 2-2. The release paths contributing to radioactive airborne releases during this reporting period were the auxiliary building vent stack, Unit 1 containment purge stack, Unit 2 containment purge stack, drumming area vent stack, gas stripper building ventilation exhaust, combined air ejector decay exhaust and turbine building ventilation exhaust.
There was one gas decay tank release during this report period.

6.0 NON-RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM In accordance with Amendment Nos. 29 and 33 to Facility Operating Licenses DPR-24 and DPR-27, respectively, dated November 4, 1977, the Environmental Technical Specifications for the Point Beach Nuclear Plant, Units 1 and 2, were modified to allow temporary suspension of the non-radiological envi-ronmental monitoring program pending NRC review of the summary report of the five years of monitoring. As a result, the semiannual report speci-fied by Item 16.6.2.a of the Technical Specification is not applicable.

7.0 NON-RADIOACTIVE CHEMICAL RELEASES 7.1 Scheduled Chemical Waste Releases Scheduled chemical waste releases to the circulating water system for the period of July 1, 1983, to December 31, 1983, included 5,451,047 gallons of neutralized clear water waste. The waste water contained 697 pounds of suspended solids and 284,912 pounds of dissolved solids.*
The concentration increases of chemical waste in the circulating water system during the period of chemical releases ranged from 0.126 to 17.298 ppm dissolved solids and from 0.001 to 0.046 ppm suspended solids.**
Plant chemical records indicated that the following amounts of chemicals were released in the form of neutralized waste:
Sodium 57,523 pounds Sulfate 156,046 pounds
- Chemical releases calculated are based upon neutralized tank analysis prior to discharge.
- Based on calculations during times of actual discharges for each individual neutralizing tank.
7.2 Miscellaneous Chemical Waste Releases Miscellaneous chemical waste releases to the circulating water system from the retention pond for the period of July 1,1983 to December 31, 1983, included 17,629,000 gallons of clear water waste. The waste water contained 1,143 pounds of suspended solids and 77,229 pounds of dissolved solids.*
Retention pond analysis and plant chemical records indicate that the following chemicals were released in the form of clear water waste from the retention pcad.
Sodium 8,833 pounds Chloride 13,631 pounds Phosphate 114 pounds The balance of the dissolved solids were in the form of soluble calcium and magnesium compounds resulting from the plant makeup water cold lime softening process.
- Chemical release calculations are based on retention pond analyses during the period July 1, 1983 to December 31, 1983.
8.0 CIRCULATING WATER SYSTEM OPERATIONS The circulating water system operation during this reporting period for periods of plant operation is described in Table 8-1.
