Good catch. Reagan always said: take what we can now, and come back for the rest later.
This may come as a shock to you, but I believe that some gasses deplete the ozone, and should be restricted. You'll notice that the restrictions were not outrageously expensive and did not give the Environmentalists that much ammunition.
Furthermore, and I guess this is the stuff you want me to get into: Reagan had proven himself to be a Conservative at heart. Nearly all of his actions advanced the cause, or at least didn't do anything to hinder it. Bush has taken on liberal issue after liberal issue, signing laws that were clearly unconstitutional, and refusing to use his veto over anything: his dedication to conservative and small-government issues is in question, maybe not to you, but to many on the Right.
At a time when we are seeing government power expand by leaps and bounds, this report comes to light, which will eventually be used to expand the government further via new regulations, laws, taxes, and policies.
This report will energize large portions of the Left, and the administration inaction in the face of its own admition will infuriate and galvanize them, even if they are hypocrites about the whole thing.
IMO, Reagan would never have let this report see the light of day.
