When I was discussing Emergency Preparedness with the owner of a local gas station, I suggested that all gas stations should have backup generators, possibly subsidized by FEMA. But the gas station owner said that in a far-reaching power failure, gas stations probably would not even be receiving gasoline - due to non-working pumps at the gasoline distributors, non-functioning traffic signals on the trucks' routes, etc.
So it seems that the gasoline-distribution system would enjoy much-improved resilience, if at least some selected gas stations were supplied by pipeline, instead of by trucks. These might just be a handful of stations that are already nearby the existing fuel pipelines. And/or stations that are along heavily-traveled truck routes, such as I-5 and I-95.
