2005 NEC Residential Grounding

I'm upgrading the electrical service in my Minneapolis home from 60 amp to 200 amp. The service entrance, from weatherhead to the main panel, is installed. The next step is grounding the system. The 2005 NEC is unavailable in my library and I can't find a Minnesota Code resource and I want to know what is required for this step. The inspector's office has been short, unprofessional, and unwilling to answer my questions. All of the books I'm referencing (including Wiring Simplified and Rex Cauldwell's Wiring a House) seem to have variations.

I think I'm supposed to ground from the neutral bus bar to a water pipe within 5 feet of where it enters the house, and supplement it with a grounding rod. This would entail running 6 AWG copper from the main panel approximately 30 feet to a point near the water meter, then bonding to a grounding rod that's already in place a few feet away in a

sump pit.

Does anyone know the code requirements for grounding according to the

Thank you, Alan
