OGE Energy reports Supreme Court declines to hear Regional Haze case The U.S. Supreme Court denied a petition filed by Oklahoma Gas and Electric and Oklahoma Attorney General Scott Pruitt asking the high court to review a 10th Circuit Court of Appeals decision on Regional Haze. The question that the Supreme Court declined to review is whether the Environmental Protection Agency acted appropriately in rejecting Oklahoma's plan to address visibility at national parks and wildlife areas. OG&E previously estimated that compliance with the EPA's plan would require an investment of more than $1B. "We are disappointed on behalf of our customers," said OG&E spokesman Paul Renfrow. "We still believe that the Oklahoma State Implementation Plan would have enabled us to meet the Regional Haze requirements at a much lower cost. However, we accept the Court's ruling and now turn our attention to meeting the 55-month compliance deadline." Renfrow added that the company would soon announce how it would comply with the EPA's mandates.
