SUPPLEMENTARY INFORMATION: Throughout this document wherever ``we,'' 
``us,'' or ``our'' is used, we mean the EPA.
    On October 11, 2018 (83 FR 51403), we published in the Federal 
Register a proposed rule pertaining to revisions to the regional haze 
SIP and FIP for Wyoming and requested comment by November 13, 2018. 
Specifically, the SIP revisions modify the sulfur dioxide 
(SO2) emissions reporting requirements for Laramie River 
Station Units 1 and 2. The revisions to the FIP revise the nitrogen 
oxides (NOX) best available retrofit technology (BART) 
emission limits for Laramie River Units 1--3 and establish a 
SO2 emission limit averaged annually across both Laramie 
River Station Units 1 and 2.
    We received a request from several organizations to extend the 
comment period and, in response, we are extending the comment period to 
December 10, 2018.\1\
