230kV UG cable termination pothead and surge arrester support structure

Does 230kV UG cable termination pothead and surge arrester support structure needs to be IEEE 693 seismic qualification in California? or ASCE 113 will be sufficient?

At this stage, no vendor has been selected for either piece of equipment, and as such, it is unclear whether the final products will include prior seismic qualification, such as shake table testing or static pull testing. We are trying to avoid potential delays in the design and trying to find out whether we can proceed with ASCE 113. Please provide if there is references on this. Thanks.
