Oklahoma Attorney General Scott Pruitt has asked the state's environmental agency to delay a hearing Monday on a new plan by Tulsa-based utility Public Service Co. of Oklahoma to deal with regional haze.
But Oklahoma Department of Environmental Quality officials said the hearing will proceed as planned at 1 p.m. Monday in Oklahoma City.
Pruitt sent a letter to the department on Wednesday outlining his concerns over a revised state implementation plan for limiting power plant emissions affecting visibility at federal parks and wilderness areas.
In his letter, Pruitt said new information about PSO's future power requirements could affect cost estimates for its revised implementation plan for regional haze. PSO wants to phase out the last two coal units at its Northeastern Station plant by 2026.
PSO earlier estimated the plan would cost more than $350 million and increase customer rates by at least 11 percent starting in 2016. A group of large industrial consumers estimates PSO's plan could cost as much as six times more than a federal implementation plan for regional haze.
The utility has more than 530,000 electricity customers in eastern and southwestern Oklahoma.
The Department of Environmental Quality has been taking public comments on PSO's revised regional haze plan since the hearing was announced April 18. The comment period will close at 3 p.m. Monday.
The plan came out of a settlement reached last year by PSO, the Environmental Protection Agency, the Sierra Club and Oklahoma Environment Secretary Gary Sherrer.
