If so, the feeder neutral conductor should be insulated, the feeder cable should include an equipment grounding conductor that runs from the pole service equipment grounding lug or neutral bar in to the basement panel equipment grounding bar (not neutral bar), the structure’s metal water system AND at least one ground rod should be bonded to the basement panel equipment grounding bar (not neutral bar) and the basement panel neutral bar should be left unbonded. Circuits fed by the panel should be wired with neutrals on the neutral bar and EGCs on the ground bar. In some cases you may be permitted to omit the grounding conductor from the feeder, bond the basement panel neutral and treat it as a service disconnect. That is up to the local AHJ.

I think that 250.28 exception no.1
applies here.
Where more than one service disconecting means is located in an assembly listed for use as service equipment, an unspliced main bonding jumper shall bond the grounded conductor(s) to the assembly enclosure.
