anyone aware of any way of supporting those organizations? Monetary assistance aside?

Perhaps.

I think the elephant in the room is the fact this is a last minute "oh shit" action. Since the current council didn't push for anything to get done for 6 years (I think). So it may just be rushed honestly.

That's a good question. I guess it depends what the details written down are.

The Federal Clear Air Act mentions "Major sources" which would cover any similar areas. But hard to say with what Wolf put out.

I have no doubt it's all still milk toast and should be beefed up for actual environmental hard prevention. I think the most charitable position is Wolf is possibly improving emissions control slightly, while also preventing PA from losing a huge payout needed for improving infrastructure (mainly highways so it's meh).

From the article:

"The emergency rulemaking was undertaken after the House Environmental Resources and Energy Committee voted to review the final-omitted version of the regulation, causing a delay in the regulatory process that would extend beyond the December 16 deadline."
