RULES

Approval and Promulgation of Air Quality Implementation Plans; States of Michigan and Minnesota;
Regional Haze [FR DOC# 2013-23394] SUMMARY: In this notice of final rulemaking, EPA is disapproving in
part the Michigan and Minnesota regional haze State Implementation Plans (SIPs) for failure to mandate
best available retrofit technology (BART) for taconite facilities within these states. This final rule
supplements a February 6, 2013, action that established Federal emission limits representing BART for
these facilities.

Approval and Promulgation of Air Quality Implementation Plans; West Virginia; West Virginia’s
Redesignation Request for the Wheeling, WV-OH 1997 Annual Fine Particulate Matter Nonattainment Area
to Attainment and Approval of the Associated Maintenance Plan [FR DOC# 2013-23691] SUMMARY: EPA is
approving a redesignation request and State Implementation Plan (SIP) revision submitted by the State of
West Virginia. The West Virginia Department of Environmental Protection (WVDEP) requested that the
West Virginia portion of the Wheeling, WV-OH fine particulate matter (PM<INF>2.5</INF>) nonattainment
area (“Wheeling Area” or “Area”) be redesignated as attainment for the 1997 annual PM<INF>2.5</INF>
national ambient air quality standard (NAAQS). In this rulemaking action, EPA is approving the 1997 annual
PM<INF>2.5</INF> redesignation request for the West Virginia portion of the Area. EPA is also approving
the maintenance plan SIP revision that the State submitted in conjunction with its redesignation request.
The maintenance plan provides for continued attainment of the 1997 annual PM<INF>2.5</INF> NAAQS
for 10 years after redesignation of the West Virginia portion of the Area. The maintenance plan includes a
comprehensive emissions inventory that EPA is approving in this rulemaking. The maintenance plan also
includes an insignificance determination for the onroad motor vehicle contribution of PM<INF>2.5</INF>,
nitrogen oxides (NO<INF>X</INF>), and sulfur dioxide (SO<INF>2</INF>) for the West Virginia portion of
the Area for purposes of transportation conformity. EPA is also approving West Virginia’s insignificance
determination for transportation conformity. In addition, EPA is also finding that the Area continues to attain
the standard. This rulemaking action approving the 1997 annual PM<INF>2.5</INF> NAAQS redesignation
request, maintenance plan, comprehensive emissions inventory, and insignificance determination for
transportation conformity for the West Virginia portion of the Area is based on EPA’s determination that the
Area has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA).

Revisions to the California State Implementation Plan, Antelope Valley Air Quality Management District [FR
DOC# 2013-23247] SUMMARY: EPA is finalizing approval of revisions to the Antelope Valley portion of the
California State Implementation Plan (SIP). This action was proposed in the Federal Register on July 26,
2013 and concerns standards for continuous emissions monitoring systems and oxides of sulfur (SOx)
emissions. We are approving local rules that regulate continuous emissions monitoring systems and
standards for gaseous sulfur emission sources under the Clean Air Act (CAA or the Act).
