1 I WOODBORER STUD 1 ASSOCIATED WITil TIIE OYSTER CREEK GENERATING STATION by B.R. Richards, C.I. Belmore, and R.E. Ilillman INTRODUCTION The William F. Clapp Laboratories of Battelle's Columbus Laboratories is conducting an investigation to determine whether the I

generating station is affecting the resident marine borer population in Oyster Creek to the extent that that population is contributing significantly to marine borer-caused damage in Barnegat Bay.

A description of the program and procedures used may be found in the First Quarterly Report on Woodborer Study Associated with 1; the Oyster Creek Generating Station, Report No. 14647, dated October 31, 1975, with the exception that the marine borer larvae program was discontinued in November, 1977.

This report presents the summary data for the fourteenth quarterly period from August 11 through November 10, 1978.

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 weeks of September 5-8, October 2-4, and November 7-10.

1978. Long-term and short-term panels at all stations were retrieved I and replaced.

I 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.
