The statement in question is this:
SEPP (or Fred Singer) has also commented on the question of [[Ozone
depletion]], making the clearly false assertion that the statement "CFCs
with lifetimes of decades and longer become well-mixed in the atmosphere,
percolate into the stratosphere, and there release chlorine." is
controversial [

This seems unobjectionable. There is certainly no credible evidence to the
contrary.
Huh? If there is no evidence to the contrary, how can he say that it's
clearly false?
