{{#Wiki_filter:UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August 17, 2009 Mr. Edward D. Halpin Chief Nuclear Officer STP Nuclear Operating Company South Texas Project P.O. Box 289 VVadsworth, TX 77483 SUB~IECT: SOUTH TEXAS PRO~IECT, UNITS 1 AND 2 - CORRECTION TO CORRECTION LETTER DATED DECEMBER 2,2008, REGARDING AMENDMENTS 188 AND 175 TO RELOCATE SURVEILLANCE TEST INTERVALS TO LICENSEE-CONTROLLED SURVEILLANCE FREQUENCY CONTROL PROGRAM (RISK-INFORMED INITIATIVE 5-b), ISSUED ON OCTOBER 31,2008 (TAC NOS. MD7058 AND MD7059)
Dear Mr. Halpin:
On October 31, 2008, the Nuclear Regulatory Commission (NRC) issued Amendment No. 188 to Facility Operating License No. NPF-76 and Amendment No. 175 to Facility Operating License No. NPF-80 for South Texas Project (STP), Units 1 and 2, respectively, in response to your application dated October 23,2007. That document was e-mailed to you on October 31,2008, and declared in the NRC Agencywide Documents Access and Management System (ADAMS) at ADAMS Accession No. ML082830172. The amendments revised the Technical Specifications (TS) by relocating the surveillance frequencies of most of the surveillance tests from the TS to a licensee-controlled surveillance frequency control program. The distribution of the amendments was performed by the then newly developed electronic distribution (Listserv) process. The distribution was accomplished by scanning the document in ADAMS, and e-mailing it to recipients on the STP Listserv e-mail distribution list (plant mailing list). A scanning error was rectified in the correction letter dated November 17, 2008 (ADAMS Accession No. ML083170477); however, that correction letter inadvertently omitted TS page 3/42-2 from the TS pages issued as an enclosure to the November 17, 2008, correction letter. That error was corrected by letter dated December 2, 2008, by restoring the TS page 3/4 2-2 which was inadvertently omitted from the November 17, 2008, letter. On February 4, 2009, STP Nuclear Operating Company (STPNOC) informed the NRC staff that TS pages 3/4 3-44,3/43-49,3/45-1, 3/45-4, and 3/4 8-13a, sent to the NRC staff, were not updated to reflect the changes on those pages approved in the intervening amendments, because those amendments had not been implemented at the time when STPNOC forwarded them to NRC. This administrative error affected only TS pages 3/4 3-44, 3/43-49, 3/45-1, 3/4 5-4, and 3/4 8-13a of Amendment Nos. 188 and 175, dated October 31, 2008, and does not change the staff's conclusions regarding Amendment Nos. 188 and 175. Enclosed are
E. Halpin - 2 corrected pages 3/4 3-44, 3/4 3-49, 3/45-1, 3/45-4, and 3/4 8-13a for Amendment Nos. 188 and 175; please replace them in the amendment issued on October 31,2008. Sincerely, bO\\-'w~ 'L&,~~ ---Pv Mohan C.
