The gloves are off in Harrisburg. We previously told you about Gov. Wolf’s plan to have PA join with northeastern states in the so-called Regional Greenhouse Gas Initiative (RGGI), a regional alliance to slap a carbon tax on natural gas-fired electric plants (see Gov. Wolf Goes Bonkers: EO Destroying Gas-Fired Elec, Carbon Tax). PA Rep. Daryl Metcalfe (Republican from Butler County, PA), Majority Chair of the House Environmental Resources and Energy Committee, sent a letter yesterday to the RGGI Executive Committee saying PA has a “rogue Governor” (his exact words) who lacks the authority to force PA to participate in RGGI without legislative approval.
