The Baseball Guru - Fans Speak to Joe Mock, Ballpark Dimensions
This is a pretty good answer regarding the waiver of Rule 1.04. The year was actually 1958 and it was probably due to the 250 foot line at the LA Coliseum with the high screen that Wally Moon took advantage of with his "Moon Shots". The article said Cincy got a waiver, I am not sure if the Great American Ballpark was mentioned in the list. Not meaning to be argumentative, it's just that the rule brings up a lot of wonderful baseball history.
