INDIANAPOLIS (AP) — Republican Gov. Mike Pence is praising the Supreme Court ruling against the Obama administration’s attempt to limit power plant emissions of hazardous air pollutants including mercury.

Indiana was among the state petitioners in one of three appeals that the court ruled on Monday.

Pence says the administration’s approach of placing environmental concerns above all others has been costly to Indiana.

However, an environmentalist says the ruling may have only a limited impact in Indiana.

Jodi Perras (PEHR‘-es), Indiana representative for the Sierra Club’s Beyond Coal Campaign, says most Indiana utilities already have decided how they’ll meet the pollution rule and only a few coal-powered plants operate without such pollution controls.

Perras says the Obama administration needs to propose a revised rule that restores at least the same level of protections.
