Palisades 1986 Environmental Annual Report Addendum A.
Introduction This supplement to the Palisades 1984 Environmental Monitoring Annual Report incorporates a total of twenty-five (25) pieces of analytical data that were unavailable during initial report preparation. The following sampling media types affected by the additional data are: _1) crops, 2) sediment and 3) aquatic biota. There were no significant changes in data interpretation with the incorporation of the completed results.
Sampling media data changes in the Environmental Monitoring Program are detailed in Table RSD-E-03A.
Table RSD-E-03D tabulates the high, low and average annual concentration of isotopes per sampling location. All data changes are noted in the right-hand margin.
B.
Discussion and Interpretation of Results 1.
Sediment Ten (10) previously unavailable sample results (5-Sr89 and 5-Sr90) were incorporated into the 1984 Environmental Monitoring Annual Report. With the additional data, one (1) reporting location was changed. The highest concentration of Sr89 shifted from the South Haven beach location to the plant discharge. All other reporting locations (per specified isotope) remained the same; although there was a slight increase in reporting average for Sr-90.
No reportable levels of Sr-89 or Sr-90 were reached.
2.
Fish Initially, ten (10) previously unavailable analyses (5-Sr89 and 5-Sr90) were to be incorporated into the Palisades supplemental Environmental Annual Report. However, due to some analytical errors and lack of enough remaining sample quantities to complete any reanalyses; only eight (8) sample results (4-Sr89 and 4-Sr90) could be used. There were no changes in highest reporting locations for either Sr89 or Sr90 concentrations. Loss of the two (2) data results did not appear to adversaly affect the Environmental Monitor-ing Program. No reportable limits for Sr-89 or Sr-90 were exceeded.
3.
Crops Again, twelve (12) previously unavailable analyses (2-gross beta, 5-Sr89 and 5-Sr90) were to be incorporated into the supplemental Environmental Annual Report. However, due to some analytical errors and limited sample quantities for the reanalyses; only seven (7) sample results (1-gross beta, 3-Sr89 and 3-Sr90) could be used.
With the additional data, both the Sr-89 and Sr-90 highest reporting locations were changed to location JS (3.5 mi SE of Palisades). The isotopic averages for Sr-89 and Sr-90 also increased. The missing IC0985-0223A-HP01
-: t data appeared to have minimal impact on the Environmental Sampling locations. No Sr-89 or Sr-90 limits were exceeded.
C.
Summary No required Technical Specification analyses were missed in 1984.
Seven (7) analytical results (1 gross beta, 3-Sr89 and 3-Sr90) were missing because of the unavailability of adequate sample quantities (per spec-ified media) for reanalysis. The missing. results did not constitute a significant reduction in the overall Env: ronmental Program. No re' port-ing levels of Sr-89 or Sr-90 were exceeded.
