Telco ground: meter panel vs service panel
This is OK, as long as Dominion's happy, which they seem to be
Meter sockets upstream of the service disconnect generally pick up ground by being bonded to the neutral.  (This is OK because you haven't hit the service disconnect yet, so there is no separation between neutral and ground at this point.)  As a result, NEC 250.94(A) point 4 permits the Intersystem Bonding Termination (IBT) to be connected to the meter enclosure or to a bonding jumper connected to the meter enclosure.
However, since this is the meter enclosure we're dealing with, the NEC doesn't have the last word here.  Utilities can and do set rules about the treatment of their cash register that go above and beyond what the NEC has to say about the topic, and some utilities indeed prohibit attaching grounding conductors or devices to meter sockets.  In the case of Dominion, Section 240.11 of their Blue Book requires that bonding connections to the meter be made using an appropriate watertight (compression) fitting (&quot;Kenny&quot; clamp or equivalent) in a ½&quot; KO to bring the bond wire into the meter base, where it can land on a dedicated terminal screw there.
