One way to neuter the EPA is to require them to provide reports on the human and economic impacts of any proposed policy, and then get approval from Congress before implementing it.
As it is, they are specifically excluded from economic impact requirements before dictating environmental policy.
It's an organization that benefits be creating more rules and programs that destroy jobs and competitiveness. They are mostly useless and point to trivial garbage as testaments to their success and need. They hop on every populist bandwagon, they are politicized and they are redundant because this is a function federal law enforcement and states should handle. The EPA is a bunch of GS11 - 14s plus executive schedule paid folks that make their money generating papers and keeping records that mean little in the grand scheme of things. Another 11 billion in tax dollars to people that create no wealth! The EPA has no product or service, rather they deliver this abstract notion of environmental security/safety and the 11 billion they cost the tax payer is the tip of the iceberg. The real cost is in the form of restrictions and delays as well as burdensome administrative garbage that still costs man-hours they cost those people that do create wealth. The very existence of this agency was a political expedient action to benefit political careers (Nixon and some others) in a time of growing environmentalist concerns. It's another centralized approach where you have Washington decide, thousands of special rules, government initiatives and programs, social experiments, exemptions and statuses and games being played so that winners and losers are decided politically rather than in a free market place.

That's a capital idea! It's high time for the EPA to produce economic impact statements for any new regulations that they propose, at the least, cap their budget and then require them to produce economic impact statements for all of their regulations already in effect.
