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...
EPA is taking direct final action on additional revisions to the final Transport Rule (Federal Implementation Plans: Interstate Transport of Fine Particulate Matter and Ozone and Correction of SIP Approvals published August 8, 2011). In the proposed , published October 14, 2011, EPA sought additional comment on unit-level operational information similar to the information supporting the proposed revisions, which specifically addressed post-combustion pollution control equipment and immediate- term operational requirements necessitating non-economic generation based on verifiable data. Based on comments received, EPA is finalizing adjustments that result in revisions to 2012 and 2...
EPA is proposing to approve, with one condition, State Implementation Plan (SIP) revisions submitted by the Pennsylvania Department of Environmental Protection (PADEP) on June 17, 2011. These revisions include the 1997 fine particulate matter (PM) National Ambient Air Quality Standard (NAAQS) attainment plan for the Liberty-Clairton nonattainment area (Liberty-Clairton Area) including a request for EPA to make a determination that the appropriate attainment deadline for this nonattainment area is April 5, 2015. EPA is proposing to approve the attainment plan for the Liberty-Clairton Area that includes the emissions inventories, the reasonably available control measures/reasonably available control technology (RACM/RACT), reasonable further progress (RFP), and contingency measures portio...
EPA is proposing to approve a State Implementation Plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions pertaining to Pennsylvania's nonattainment New Source Review (NSR) program incorporate preconstruction permitting regulations for fine particulate matter (PM<INF>2.5</INF>) into the Pennsylvania SIP. EPA is approving these revisions in accordance with the requirements of the Clean Air Act (CAA).
EPA is taking direct final action to approve the fine particulate matter (PM<INF>2.5</INF>) 2002 base year emissions inventory portion of the State Implementation Plan (SIP) revision submitted by the State of Georgia on October 27, 2009. The emissions inventory is part of the Rome, Georgia (hereafter referred to as ``the Rome Area'' or ``Area''), PM<INF>2.5</INF> attainment demonstration that was submitted for the 1997 annual PM<INF>2.5</INF> National Ambient Air Quality Standards (NAAQS). This action is being taken pursuant to section 110 of the Clean Air Act (CAA).
EPA is taking direct final action to approve the fine particulate matter (PM<INF>2.5</INF>) 2002 base year emissions inventory, portion of the State Implementation Plan (SIP) revision submitted by the State of Georgia on July 6, 2010. The emissions inventory is part of the Atlanta, Georgia (hereafter referred to as ``the Atlanta Area'' or ``Area''), PM<INF>2.5</INF> attainment demonstration that was submitted for the 1997 annual PM<INF>2.5</INF> National Ambient Air Quality Standards (NAAQS). This action is being taken pursuant to section 110 of the Clean Air Act (CAA).
On June 17, 2010, the State of Alabama, through the Alabama Department of Environmental Management (ADEM), Air Division, submitted a request for EPA to redesignate the Birmingham fine particulate matter (PM) nonattainment area (hereafter referred to as the ``Birmingham Area'' or ``Area'') to attainment for the 2006 24-hour PM National Ambient Air Quality Standards (NAAQS); and to approve a State Implementation Plan (SIP) revision containing a maintenance plan for the Area. The Birmingham 2006 24-hour PM nonattainment area is comprised of Jefferson and Shelby Counties in their entireties and a portion of Walker County. EPA is proposing to approve the redesignation request for the Birmingham Area, along with the related SIP revision, including Alabama's 2009 emissions inventory for the Ar...
