A plan the federal Environmental Protection Agency says is needed to reduce air pollution in Oklahoma is being called “an attack on affordable electricity” by Republican U.S. Sen. Jim Inhofe.

The EPA says a new clean air proposal would reduce sulfur dioxide emissions from three Oklahoma coal-fired power plants by 95 percent.

The trio of generation facilities contributes more than one-third of the SO2 pollution from the hundreds of sources in Oklahoma.

Inhofe, who is the top Republican on the Senate environment committee, criticized the federal agency for rejecting a state plan to reduce air pollution.

The EPA has opened a 60-day public comment period on its proposal to have the three power plants either add scrubbers or to stop using coal and switch to natural gas.

THREE POWER PLANTS:

OG&E Muskogee

OG&E Sooner Plant (Red Rock)

PSO Oologah

A public hearing on the proposal is scheduled for April 13 from 4-6 p.m. at Metro Tech’s Springlake Campus in the Business Conference Center.
