Administrative, environment
Plaintiff has standing, as he lives near a mine, and regulations would incentivize reduced emissions and mean quicker cleanups.
Other plaintiffs have standing due to living near rivers.
Putative intervenors do no have Article III standing, as the order merely sets a date for rulemaking, and there is no showing that notice and comment would be insufficient. No statutory standing, as there's no impairment of interests.
Putative intervenors' arguments construed as amici, rejected.
