Federal Register / Vol. 86, No. 138 / Thursday, July 22, 2021 / Proposed Rules partially disapproved Oklahomas Regional Haze SIP and partially approved and partially disapproved Oklahomas SIP submission addressing its prong 4 visibility transport requirements for the 1997 8-hour Ozone NAAQS and the 1997 PM2.5 NAAQS on December 28, 2011. Oklahoma noted that in the same action, EPA
promulgated a FIP addressing the disapproved portions of Oklahomas 2010 Regional Haze SIP and the interstate visibility transport SIP
revisions for the 1997 8-hour Ozone NAAQS and the 1997 PM2.5 NAAQS, and that EPA found that the controls under this FIP, in combination with the controls required by the portion of the Oklahoma Regional Haze SIP submittal approved by EPA, will serve to prevent sources in Oklahoma from emitting pollutants in amounts that will interfere with efforts to protect visibility in other states. Oklahoma also noted that it submitted a revision to its regional haze and interstate visibility transport SIPs 2013 Oklahoma Regional Haze SIP
Revision on June 14, 2013, to replace the FIP as it relates to the AEP/PSO
Northeastern Units 3 and 4, and that EPA approved this revision effective April 7, 2014. Oklahoma asserted that any contribution to visibility impairment or interference with any other states measures to protect visibility attributable to SO2 emissions are addressed through Oklahomas 2010
Regional Haze SIP as revised in the 2013
Oklahoma Regional Haze SIP Revision and through EPAs related regional haze actions in Oklahoma. This includes EPAs FIP action that currently addresses the OG&E Sooner Units 1 and 2 and the OG&E Muskogee Units 4 and 5. Oklahoma also noted that although no additional visibility protection obligations are anticipated on Oklahomas part as a result of the revised 2010 1-hour SO2 NAAQ, other program actions taken to ensure maintenance of the revised SO2 NAAQS
will indirectly assist in avoiding interference with any other states measures to protect visibility.
On June 16, 2016, Oklahoma submitted a SIP revision to address the infrastructure requirements for the 2012
PM2.5 NAAQS, including the transport requirements. In its evaluation, Oklahoma stated that the 2010 Regional Haze SIP describes Oklahomas measures to protect visibility and ensure that emissions do not interfere with any other states measures to protect visibility. Oklahoma stated that these measures include provisions in the Oklahoma Administrative Code 252:1008, Part 11. Oklahoma noted

In its evaluation, Oklahoma asserted that any contribution to visibility impairment or interference with any other states measures to protect visibility attributable to emission of PM2.5 or its precursors e.g., SO2 are addressed through Oklahomas 2010
Regional Haze SIP as revised in the 2013
Oklahoma Regional Haze SIP Revision and through EPAs related regional haze actions in Oklahoma.

On October 25, 2018, Oklahoma submitted a SIP revision to address the CAA section 110a1 and 110a2

Oklahoma Administrative Code 252:1008, Part 11. Oklahoma noted that EPA partially approved and partially disapproved Oklahomas Regional Haze SIP and partially approved and partially disapproved Oklahomas SIP submission addressing the visibility prong of interstate transport for the 1997 8-hour Ozone NAAQS and the 1997 PM2.5 NAAQS on December 28, 2011. Oklahoma noted that in the same action, EPA
promulgated a FIP addressing the disapproved portions of Oklahomas 2010 Regional Haze SIP and the interstate visibility transport SIP
submittals for the 1997 8-hour Ozone NAAQS and the 1997 PM2.5 NAAQS, and that EPA found that the controls under this FIP, in combination with the controls required by the portion of the Oklahoma Regional Haze SIP submittal approved by EPA, will serve to prevent sources in Oklahoma from emitting pollutants in amounts that will interfere with efforts to protect visibility in other states. Oklahoma also noted that it submitted a revision to its regional haze and interstate visibility transport SIPs on June 14, 2013, to replace the FIP as it relates to the AEP/PSO Northeastern Units 3 and 4, and that EPA approved this revision effective April 7, 2014. In its evaluation, Oklahoma asserted that ozone from ozone precursor emissions are not believed to contribute significantly to visibility impairment and that Oklahomas 2010 Regional Haze SIP demonstrates that Oklahomas PM2.5 emissions do not interfere with any other states measures to protect visibility. Oklahoma noted that this portion of the 2010 Regional Haze SIP
was approved by EPA on December 28, 2011. Additionally, the submission includes a technical support document TSD 16 intended to address the requirements of CAA section 110a2DiI, which requires a states SIP to contain adequate provisions prohibiting any source or other type of emissions activity within the state from emitting any air pollutant in amounts which will contribute significantly to nonattainment in, or interfere with maintenance by, any other state with respect to any such national primary or secondary ambient air quality standard i.e., prongs 1 and 2. In that document, Oklahoma asserted that the Oklahoma Department of Environmental Quality ODEQ has determined that Oklahoma meets the 16 See Oklahoma Demonstration of Compliance with the Good Neighbor Requirements of Clean Air Act Section 110a2DiI for the 2015 Ozone National Ambient Air Quality Standard, which is part of Oklahomas October 25, 2018 Infrastructure SIP submittal for the 2015 Ozone NAAQS.
