(j)(1) EPA is disapproving a narrow portion of West Virginia's August 31, 2011 submittal because it does not satisfy the requirement that emissions of PM_2.5 and PM_10 shall include gaseous emissions which condense to form particulate matter at ambient temperatures. This disapproval extends only to the lack of condensable emissions within the definition of “regulated NSR pollutant,” found at 45CSR14 section 2.66, and does not alter EPA's October 17, 2012 (77 FR 63736 https://www.federalregister.gov/citation/77-FR-63736) approval of the remaining portions of West Virginia's August 2011 SIP submittal.
(2) EPA is disapproving specific portions of West Virginia's infrastructure SIP submissions dated December 3, 2007, December 11, 2007, April 3, 2008, October 1, 2009, October 26, 2011, and February 17, 2012 which address certain obligations set forth at CAA sections 110(a)(2)(C), (D)(i)(II) and (J) relating to the West Virginia PSD permit program. Because West Virginia's definition of “regulated NSR pollutant” in 45CSR14 does not address condensables for PM_2.5 and PM_10 emissions, EPA is determining that West Virginia's infrastructure SIP submissions do not meet certain statutory and regulatory obligations relating to a PSD permit program set forth at CAA sections 110(a)(2)(C), (D)(i)(II) and (J) for the narrow issue of condensables as set forth in the following table.
Submittal dates NAAQS Infrastructure element(s) disapproved in this action December 11, 2007; April 3, 2008 1997 PM_2.5 110(a)(2)(D)(i)(II). December 3, 2007; December 11, 2007 1997 ozone 110(a)(2)(D)(i)(II). October 1, 2009 2006 PM_2.5 110(a)(2)(D)(i)(II). October 26, 2011 2008 lead 110(a)(2)(D)(i)(II), (C), and (J). February 17, 2012 2008 ozone 110(a)(2)(D)(i)(II), (C), and (J).
