text: Statutory and constitutional reasons also counsel EPA not to finalize the Endangerment Proposal. An endangerment finding will trigger a regulatory cascade with potentially devastating economic impacts that Congress never intended or approved when it enacted 202. Regulatory litigation rather than legislative deliberation will determine the direction of public policy and the extent of the burdens imposed on the private sector, vitiating our democratic system. We could end up with a Mega-Kyoto system without the people's elected representatives ever casting a vote. Moreover, the only way EPA can regulate greenhouse gases under the CAA without risk of administrative chaos and economic disaster is to flout statutory language, play lawmaker, and effectively "amend" the statute, violating the separation of powers.
