I WOODBORER STUDY ASSOCIATED WITH THE OYSTER CREEK GENERATING STATION by B.R. Richards, N.J. Maciolek, C.I. Belmore, and R.E. Hillman INTRODUCTION The William F. Clapp Laboratories of Battelle's Columbus Laboratories is conducting an investigation to determine whether the generating station is affecting the resident marine borer population in Oyster Creek to tha extent that that population is contributing significantly to marine borcr-caused damage in Barnegat Bay.

A description of the program and procedures used may be found in the Draf t Annual Report on Woodborer Stely Associated with the Oyster Creek Generating Station, Report 14968, dated February 9, 1980.

This report presents the summary data for the nineteenth quarterly period from November 9, 1979 through February 8, 1980.

I PROCEDURES AND INTERIM DATA Exposure Panels The long-term and short-term exposure panels were retrieved and replaced with new untreated pre-soaked (for two weeks) panels at the 20 exposure sites in Barnegat Bay and adjacent waters (Figure 1) during the periods of December 12-13, 1979, January 7-9, and Febrtiary 5-6, 1.980.

]

Long-term and short-term panels at all stations were retrieved and replaced.

Table 1 describes the geographical locations of the exposure sites. The summary data for the laboratory examination of the panels may be found in Tables 2 through 5.
