PURPOSE AND HISTORY OF CODE CLEARING
An IAEI Code Clearing Committee is a term not used very often these days. This committee is sometimes
referred to by our Sections, Chapters, or Divisions as the "Codes and Standards Committee."
On the International Office (IO) level, the Codes and Standards Committee is responsible for reviewing
proposed changes to the National Electrical Code(r) as well as other electrical codes and standards
that may be submitted to IAEI for the purpose of establishing an official IAEI position. The C & S
Committee also reviews public inputs and public comments submitted to it by the International Board
of Directors, CEO or committee representatives for the purpose of establishing an IAEI voting position
and giving direction or guidance to IAEI committee representatives on those public inputs or comments.
In looking at the IAEI Genesee Chapter by-laws, Article IX, Section 1f references the "Code Clearing
Committee" as a "Standing Committee." Section 2 states that, "the scopes of the Standing Committees
shall be as approved by the Chapter Board of Directors." That is all your by-laws state about the
"Code Clearing Committee." It will be up to your Genesee Chapter Board of Directors to come up with
a scope for the committee.
In years past, I was the Secretary of the IAEI Texas Chapter for over a decade. We had a "Code
Clearing Committee" as well. In the Texas Chapter, this committee was similar to the Codes and
Standards Committee described at the International level. This committee was not as much for
"answering Code questions" as it was reviewing and developing good Code proposals to be forwarded
to the IAEI Section level (today, public inputs can be sent directly to the IO Codes and Standards
Committee). In our Chapter, the Code Clearing Committee was also responsible for nominating
candidates from the Texas Chapter to the IO for consideration to represent IAEI on an NEC Code
Making Panel (CMP).
Hope this helps you in your pursuit to figure out what you got yourself appointed to!

DO WE USE 2 GROUND RODS OR 1?
In looking at your question(s), you stated the following:
Looking for some clarification of the code reorganization in the 2011 NEC....is a second supplementary ground rod required when using the metal water pipe as your GEC when 25 ohms or less can not be proven???
Your question gets a little confusing with "as your GEC when 25 ohms or less can not be proven." I will do my best to answer your question(s) based on the 2011 NEC.
An underground metal water pipe is always required to be supplemented by an additional grounding electrode, but it does not have to be a ground rod or rods. As stated at 250.53(D)(2), a metal underground water pipe must be supplemented, but it can be supplemented by ANY of the additional electrodes specified in 250.52(A)(2) through (A)(8) (concrete-encased electrode, building steel, rise, pipe, plate, etc.). IF (by choice) the supplemental electrode is a rod, pipe, or plate type, that rod, pipe, or plate must comply with 250.53(A).
Beginning with the 2011 NEC, all rod, pipe, or plate grounding electrodes were required to be supplemented as well as underground metal water piping type electrodes. A closer look at 250.53(A)(2) will reveal that a single rod, pipe, or plate electrode must be supplemented, but again, it can be supplemented by ANY of the additional electrodes specified in 250.52(A)(2) through (A)(8) (concrete-encased electrode, building steel, ride, pipe, plate etc.). Notice that this DOES NOT include 250.52(A)(1) (underground metal water pipe).
If you choose to supplement the underground metal water piping with a ground rod, the ground rod would need to comply with 250.53(A)(1) through (A)(3), which means that yes, the single rod would need to be supplemented by an additional electrode (other than underground metal water piping). Does the Code demand that one rod be supplemented by an additional (or second) ground rod? The answer to that one is NO, the single ground rod can be supplemented by ANY of the additional electrodes specified in 250.52(A)(2) through (A)(8) (concrete-encased electrode, building steel, ride, pipe, plate, etc.). What is the cheapest, easiest way to comply with this requirement.....install a second ground rod!
Sooooooo, if you choose to supplement the underground metal water pipe with a ground rod, YES, a second grounding electrode is required (most folks choose a second ground rod) to supplement the first ground rod.
