Dear Commissioners and Staff:

805.545.3242 E*Mail: James. Welsch@pge.com 10 CFR 50.54 10 CFR 72.32 10 CFR 72.44(f)

In accordance with the requirements of 10 CFR 50.54, 10 CFR 72.32, and 10 CFR 72.44(f), Pacific Gas and Electric Company (PG&E) is providing a summary of the analysis of changes to the Emergency Plan in the associated enclosures listed below:

  • - Summary of the Analysis of Changes in Emergency Plan Section 1, Revision 4.08, "Definitions & Abbreviations"
  • - Summary of the Analysis of Changes in Emergency Plan Appendix A, Revision 4.08, "Procedures" PG&E evaluated the changes for a reduction in effectiveness, as defined in 10 CFR 50.54(q), and concluded that the changes do not reduce the effectiveness of the E-Pian. TheE-Pian continues to meet the requirements in Appendix E of 10 CFR Part 50 and the planning standards of 10 CFR 50.47(b). Therefore, PG&E concluded that prior NRC approval of the associated changes was not required.

five nautical miles.

The proposed activity does not result in any changes to emergency response planning area boundaries. The proposed activity continues to meet the intent of the regulatory definition of the LPZ.

There will be no differences in how the E-Pian is implemented. The proposed activity does not remove or alter any PARs or alter the ETE analysis in any way. The proposed activity aligns Section 1 of the E-Pian with every other section of the E-Pian as the LPZ will be consistently described as PAZs 1 and 2 with the outer boundary being 6 miles.

The change to update the LPZ distance in section 1 of the E-Pian was evaluated under 50.54(q) effectiveness evaluation 2018-02, which concluded that prior NRC approval was not required.
