Subject:

San Onofre Nuclear Generating Station, Units 2 and 3 - Issuance Of Amendments Re: Elimination Of Requirements For Hydrogen Monitors (TAC NOS. MC5401 AND MC5402)

Dear Sir or Madam:

By Reference 1, Southern Califomia Edison (SCE) requested license amendments for San Onofre Nuclear Generating Station Units 2 and 3 to eliminate requirements for hydrogen monitors from Technical Specification Limiting Condition For Operation 3.3.11, "Post-Accident Monitoring Instrumentation.' By Reference 2, the Nuclear Regulatory Commission (NRC) approved the requested amendments.

Our Reference 1 submittal contained an editorial oversight in the footnotes for Table 3.3.11-1 for both Unit 2 and Unit 3. SCE is resubmitting the enclosed pages, and request that they be reissued.
