Scoping and Screening RAI 2.3.3.6-2 and 2.3.3.18-2 By letters dated August 17 and September 7, 2010, the applicant responded to RAIs 2.3.3.6-2 and 2.3.3.18-2, and provided a description of how seismic endpoints were established at various panels. The staff was unclear how the applicant designated the endpoints as base-mounted equipment.
Discussion:
PG&E agreed to supplement its responses to RAIs 2.3.3.6-2 and 2.3.3.18-2 to address how endpoints at base-mounted equipment were established.

Discussion:
PG&E agreed to supplement its response to RAI 2.3.3.7-3 to clarify the oil filter on the abov elicense renewal boundary drawing and provide clarification on whether failure of the water traps described above could affect safety-related equipment.
