The plaintiffs, 101 self-described enviro groups, had petitioned the EPA to promulgate rules relating to spent lead ammo, arguing that the Toxic Substances Control Act required them. The EPA declined, the groups sued, lost in the trial court, and now lose on appeal.
The groups had earlier petitioned ESA to ban lead ammo, and EPA replied that TSCA has an exemption for things taxed under Pittman-Robertson, which imposes an excise tax on ammunition. So this time they came back and sought a regulation of fired projectiles, arguing that they were not subject to Pittman-Robertson.
