Default Gas meter clearance

Where in the NEC does it state that a meterbase must be at least 5' from a natural gas meter ?

It doesn't. You may find it in your local power company requirements manual though. Perhaps its a NESC requirement, or maybe just a desirement.

The gas company may have a distance requirement---I know some State Electrical inspectors here are enforcing the distance requirements per gas utility requirements in some areas.

If it's a single utility company that serves the house or building, then they are definitely enforcing their own code. I can say with certainty that it's 3-5 feet between a gas meter vent and an above ground transformer. Then it's 5 feet between the edge of an LP gas tank, and a meter base. Yeah, it depends on the serving utility.

This is directly from one of our serving utility companies:
Minimum clearances from structures, building openings, and gas meters
A minimum clearance of 3 feet is required between electric service lines and
windows, doors, porches, fire escapes, or similar openings.
A minimum horizontal clearance of 3 feet is required between electric service
equipment and natural gas meter pressure relief vent
(see Figure 14).
Service lines passing over the roof of another structure (but not attached to that
structure) must maintain the minimum clearances (see Figure 14).
Service lines passing over a deck must maintain a minimum clearance of 11 feet
(see Figure 14).

Reason I asked is because it is hard to prove it is not in the Code. To my knowledge it was not in the NEC. However this 6' clearance idea has popped up now and then for decades. If anyone has a International Gas Fuel Code I would appreciate it if they would look to see if such a rule is in that code. To my knowledge of that code I remember it being there but only if the gas meter has a vent on the meter. I received a call from a past student that was hit with this rule today on the job site. The power company called to clarify why the gas meter was within 6' of a new commercial building electrical meter. Problem is the electrician installed the meterbase and had it inspected waiting for the power company to connect. By the time the power company came to connect they found the gas meter installed by the gas company after the electrical meter was installed to be within 6' of the electrical meter. I get those type calls to confirm if there is or is not a code. Hard to open a codebook and say see that rule is not there.

Frustrating

I searched the 2008 code book (preliminary edition, so its not 100%) for "gas" and didn't see anything relevant. It was annoying in the chapters dealing with gas spacer cable and hazardous locations (flammable gases) because there we so many hits.
