ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2017-0081; FRL-9964-50-Region 5]


Air Plan Approval; Wisconsin; Site-Specific Sulfur Dioxide 
Requirements for USG Interiors, LLC

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve under the Clean Air Act a State Implementation Plan (SIP) 
revision submitted by Wisconsin on January 31, 2017, and supplemented 
on March 20, 2017. This SIP submittal consists of Wisconsin 
Administrative Order AM-16-01, which imposes a requirement for a taller 
cupola exhaust stack, a sulfur dioxide (SO2) emission limit 
in conjunction with a minimum cupola stack flue gas flow rate, and 
associated requirements on the mineral wool production process at the 
USG Interiors LLC facility located in Walworth, Wisconsin (USG-
Walworth). Wisconsin submitted this SIP revision to enable the area 
near USG-Walworth to qualify for being designated ``attainment'' of the 
2010 primary SO2 National Ambient Air Quality Standards, a 
matter that will be addressed in a separate future rulemaking. EPA is 
approving AM-16-01 into the Wisconsin SIP, which makes the AM-16-01 
requirements federally enforceable.

DATES: Comments must be received on or before August 7, 2017.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R05-
OAR-2017-0081 at http://www.regulations.gov, or via email to 
Aburano.Douglas@epa.gov. For comments submitted at Regulations.gov, 
follow the online instructions for submitting comments. Once submitted, 
comments cannot be edited or removed from Regulations.gov. For either 
manner of submission, EPA may publish any comment received to its 
public docket. Do not submit electronically any information you 
consider to be Confidential Business Information (CBI) or other 
information whose disclosure is restricted by statute. Multimedia 
submissions (audio, video, etc.) must be accompanied by a written 
comment. The written comment is considered the official comment and 
should include discussion of all points you wish to make. EPA will 
generally not consider comments or comment contents located outside of 
the primary submission (i.e. on the web, cloud, or other file sharing 
system). For additional submission methods, please contact the person 
identified in the FOR FURTHER INFORMATION CONTACT section. For the full 
EPA public comment policy, information about CBI or multimedia

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal

[[Page 31547]]

Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to this rule, no 
further activity is contemplated. If EPA receives adverse comments, the 
direct final rule will be withdrawn and all public comments received 
will be addressed in a subsequent final rule based on this proposed 
rule. EPA will not institute a second comment period. Any parties 
interested in commenting on this action should do so at this time. 
Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment. For 
additional information, see the direct final rule which is located in 
the Rules section of this Federal Register.

    Dated: June 20, 2017.
Robert A. Kaplan,
Acting Regional Administrator, Region 5.
