You're asking for an example of an environmental disaster of the type the regulation is intended to prevent that happened since the regulation came into effect, with the implication that there aren't any is evidence that the regulation is bad? I'd argue there's no way to differentiate between perfectly calibrated regulation and regulation that's too onerous by the metric you're giving, so your conclusion isn't supported without more evidence.
