Finishing up a service installation in a house in the country which is under the 2005 code, there is no copper water line coming into the house for a second source of ground. The outside currently has one 8-foot ground rod installed with a number two copper ground wire going to a 365 amp panel. There are two 200-amp main panels coming off as a service, my question is do I need to run a extra ground wire from each panel into the meter base to connect to the ground wire going to the ground rod which will have to have another ground rod installed 6 feet away from ita55
 
Something doesn't make sense in your post, you say there is a 365 amp panel(?) and two 200 amp service panels, please clarify, is the 365A (most likely a 320/400 A) actually the service equipment?

The basics are you would most likely need two 8' rods and a #6 to the service equipment assuming the main bonding jumper is there.

My apologies,320 amp meter base.utility required a #2 copper ground wire
Since the home has all plastic plumbing i will need to put in a second ground rod 6 feet away from other rod.so my question is whether i need to pull a grounding conductor from each inside panel to the meter base,or am i good with just the neutrals between the two,conduit is pvc.area is under 2005 code.thanks for input.

Yep, Op had to run a #2 because POCO does not read 250.66. Ugh.

Don't see that its under the POCOs jurisdiction.
Install a second ground rod, #6 to the first, install a second clamp on the first. GEC does not have to be continuous. Wire to second rod is a bonding jumper. 2017 NEC is very clear on this.

OP said POCO required it. They can ask for most anything they want and if you don't comply they don't have to connect service, even if NEC allows otherwise.

It was a utility requirement, OP said in some post, per NEC the above applies.

At this point he pounds in a second rod, #6 jumper connecting them, and is done. No?
 
I work in area with 3 utilitie companies,200 amp service requires #4 gec,the 320/400 amp service i installed is required to have a #2 copper gec,by the utitity supplying power.so I am planning on installing the second rod to match,just to avoid any later issue with the ahd which is a seperate entity.all thoughts are appreciated.I

Second rod meets code.

As long as AHJ and POCO agree on the termination point,no prob.

#2 to second rod, again, overkill.
