This is the very type of thing that caused so many problems in getting a workable code passed. I believe that Mr. M, a board member, said it all when he insisted that "common sense" prevail. I have minimal amounts of romex in EMT as well as PVC. As long as the EMT has watertight fittings and boxes there is no valid reason to exclude.
Many of the farms in the county have EMT w/romex, most in WP raceways. They are used for grain dryers, farrow houses, butchering houses, etc and as some are under the county health dept full inspections as to safety are performed.
