A state regulatory board Thursday approved Gov. Ed Rendell's proposal to make deeper cuts in mercury emissions from Pennsylvania's coal-fired power plants, despite opposition from power plants and mining companies.
The vote by the Independent Regulatory Review Commission came just a day before a deadline for the state to submit a mercury-regulation plan to the federal government.
If the rule becomes final, Pennsylvania will be the first major coal-producing state to require a tougher-than-federal limit on mercury emissions from power plants. Pennsylvania is second only to Texas in its level of mercury emissions.

The commission voted 3-2 along party lines, with Democrats supporting it. The Republican-controlled Legislature could still stop the rule from going forward, but any measure would have to be signed by the Democratic governor.
