2.  PARA B0204C(5) WAS INTENDED TO BE IN HARMONY WITH THE KEY 
REQUIREMENTS SPECIFIED IN THE PARA B0204C(5)(A) AND (B).  THE 
WORDING IN PARA B0204C(5) IMPLIES A FOLLOW-ON WBGT SURVEY

PUT, PARA B0204C(5) WOULD BE BETTER WRITTEN AS, "ONCE A HEAT 
STRESS SURVEY HAS BEEN CONDUCTED, FOLLOW-ON SURVEYS FOR THE 
REMAINDER OF THAT DAY AND FOR SUBSEQUENT DAYS SHALL BE 
ACCOMPLISHED AS IDENTIFIED BELOW IN PARAGRAPH B0204(5)A."
