Grounding the electrical Panel

I have asked this before but I need to get a more specific answer.
I am adding new circuits to the electrical panel.
currently there is one ground rod with a #6 solid wire coming from the ground rod to the coldwater to the circuit panel.
Local codes require a second ground rod, in which I have installed, it is 8 ft long and 5/8" diameter, 6 and 1/2 ft from first ground rod.
What I need to know is as I run a new continuous #6 wire from the second ground rod to the first ground rod, does it got directly to the grounding bar in the circuit panel or does it go to the water supply first then the circuit panel.
I ask this because I also am required to have a ground wire also, which I am not sure of, but i believe it is to be a #4, I am using stranded, from the circuit panel ground bar to the cold water, to the hot water to the gasline.
does this sound correct?
Let me reiterate
1st wire #6 from second ground rod to first ground rod to circuit panel grounding bar.
2nd wire #4 from circuit panel grounding bar to cold, to hot to gas.

Correct with exceptions.

The #4 to the cold water. If it is metal pipe in contact with the ground outside for 10 feet or more you need to connect to that pipe within 5 feet of entering the building. You also have to jump out the meter and any softner/filters which use unions or plastic manifolds.

Is the hot and gas a local thing? I know bonding gas piping is in the NEC but MANY local codes over ride that and don't want you to do it.
I have never heard of bonding the hot piping.

the hot water thing is local code, I have an hvac contractor that had an inspection on his house and he said this is what needed to be done, just verifying. I think I got it. thanks

Petey,

Don't you bond the cold water to the hot water in your area?

250.104(A)(1) requires the water pipe system(s) to be bonded. This includes both the hot and cold piping systems. In many cases this requires a jumper between the hot and cold water piping at the water heater because many water heaters have dielectric fittings.

This is correct i believe in my local, that it needs to be at the water heater. also

Thing is nowhere does it mention hot or cold. It does mention meters and similar equipment which will break the bond.

It's never been brought up by our AHJ or POCO and I have had inspectors look right at the water bond and not question it. If there were to be a heater which broke the bond I would jump it out.
