The EPA is proposing to revise the definition ``regulated NSR pollutant'' contained in two sets of Prevention of Significant Deterioration (PSD) regulations and in the EPA's Emission Offset Interpretative Ruling. This revision would correct an inadvertent error made in 2008 when the EPA issued its final rule to implement the new source review (NSR) program for fine particles with an aerodynamic diameter of less than or equal to 2.5 micrometers (PM<INF>2.5</INF>). Effectively, this revision would reestablish the interpretation that for measurement of ``particulate matter emissions'' in the context of the PSD and NSR regulations there is no explicit requirement to include measurement of condensable PM. However, the condensable portion would continue to be required for emission...

I'm not going to rule out any options," he says, "but right now I'm just focused on getting reengaged in the community here, and I honestly don't know what I'm going to do next after working with Sen. [Barbara Boxer] on the [climate change] reports for the next president. There's a wide range of opportunities, I'm sure. I'd rather net speculate as to what comes next before I figure that out.
"I left in part because I was disturbed with the policy choice that was made," Burnett says. Plus, he says he wanted to work on climate change. And then on April 2, 2007, in Massachusetts vs. EPA, the U.S. Supreme Court ruled that "greenhouse gases fit well within the Clean Air Act's capacious definition of 'air pollutant,' " and must be regulated if they endanger public health.
"It's a profound d...

EPA is approving portions of a State Implementation Plan (SIP) revision submitted by the State of Colorado for the purpose of addressing the ``good neighbor'' provisions of Clean Air Act (``Act'' or ``CAA'') section 110(a)(2)(D)(i) for the 1997 8-hour ozone National Ambient Air Quality Standards (``NAAQS'' or ``standards'') and the 1997 fine particulate matter (``PM<INF>2.5</INF>'') NAAQS. This SIP revision addresses the requirement that the State of Colorado's SIP (``Interstate Transport SIP'') have adequate provisions to prohibit air emissions from adversely affecting another state's air quality through interstate transport. In this action, EPA is approving the Colorado Interstate Transport SIP provisions that address the requirement of section 110(a)(2)(D)(i) that emissio...
