But in any case, the text is wrong. This does not say that the EPA is requesting this—it says that the EPA is properly and legally handling requests of groups petitioning them.
The EPA perfected this trick under Carol Browner in the Clinton nineties. The usual Big Enviro suspects would take them to court, demanding that they do this or that, then the EPA would “lose” to them, pay their legal fees with a wink and a grin and do as demanded.
It’s an old trick. Quite a few of the local and municipal governments and school districts that “settle” with the ACLU have no intention of fighting them and probably arrange under-the-table to be sued by them.
