, Attention: Document-Control Desk Mail Station Pl-137 I Washington, D. C. 20555 Gentlemen Subject - Oyster Creek Nuclear Generating Station Docket No. 50-219 N.J. - DEP comments on Draft FTOL SER-Due to an admistrative error, GPUN's letter of January.16, 1990, regarding the'-

above subject, omitted attachments one (1) and two (2). -Please find attached' the ommitted pages.

It must also be noted that a clarification is necessary.in our: submittal concerning the New Seismic Floor Response Spectra.' The fourth paragraph on' page ten (10), states: .

"An independent seismic evaluation of OCNGS and other l

nuclear plants in the eastern and central'U.S; was done-by the seismicity Owner's Group (SOG)-and EPRI. The study.

evaluated seismic hazards at 57. sites with the objective of.

resolving the Charleston Earthquake Issue. 'The study has been documented in EPRI.NP-6395-D,: April 1989. The USNRC and its advicer, USGS has reviewed this document: and issued a Safety Evaluation Report (SER) on. September 20, 1988." I

-The last sentence in the quotation should" read: "The USNRCland its-advisor, USGS have reviewed ~the seismic hazard methodology'.that was utilized.in.the-study and issued a Safety Evaluation Report'(SER) on. September 20, 1988."
