Association to extend the public comment period an additional 120 days 
from the closing date of November 23, 2015 and from the Fond du Lac 
Band of Lake Superior Chippewa for an unspecified period of time. EPA 
is, therefore, reopening the comment period for an additional 30 days 
after November 23, 2015.

SUPPLEMENTARY INFORMATION: On October 22, 2015, EPA proposed revisions 
to a Federal implementation plan (FIP) addressing the requirement for 
best available retrofit technology (BART) for taconite plants in 
Minnesota and Michigan. In response to petitions for reconsideration, 
we proposed to revise the nitrogen oxides (NOX) limits for 
taconite furnaces at facilities owned and operated by Cliffs Natural 
Resources (Cliffs) and ArcelorMittal USA LLC (ArcelorMittal). We also 
proposed to revise the sulfur dioxide (SO2) requirements at 
two of Cliffs' facilities. We proposed these changes because new 
information had come to light that was not available when we originally 
promulgated the FIP on February 6, 2013.

    Dated: December 4, 2015.

Regional Administrator, Region 5.
