ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 70

[EPA-R07-OAR-2014-0468; FRL-9914-51-Region 7]

Approval and Promulgation of Implementation Plans; State of 
Nebraska; Fine Particulate Matter New Source Review Requirements.

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) proposes to approve 
the State Implementation Plan (SIP) revision submitted by the State of 
Nebraska. This proposed action will amend the SIP to include revisions 
to Nebraska's Air Quality Regulations ``Definitions'', ``Construction 
Permits--When Required'', and ``Prevention of Significant Deterioration 
of Air Quality'' to make the state regulations consistent with the 
Federal regulations for the fine Particulate Matter (PM2.5) 
Prevention of Significant Deterioration (PSD) program. This proposed 
revision will amend the state minor source construction permitting 
program including the addition of a minor source permitting threshold 
for PM2.5. These revisions are necessary to properly manage 
the increment requirements (maximum allowable deterioration to the air 
quality) of the PSD program and assure continued attainment with the 
PM2.5 National Ambient Air Quality Standards (NAAQS). This 
proposed action also recognizes the state's request to not include, 
into the SIP, provisions relating to Significant Impact Levels (SILs) 
and Significant Monitoring Concentrations (SMCs). These provisions were 
vacated and remanded by the U.S. Court of Appeals for the District of 
Columbia on January 22, 2013.

DATES: Comments on this proposed action must be received in writing by 
September 3, 2014.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2014-0468, by mail to Greg Crable, Environmental Protection Agency, 
Air Planning and Development Branch, 11201 Renner Boulevard, Lenexa, 
Kansas 66219. Comments may also be submitted electronically or through 
hand delivery/courier by following the detailed instructions in the 
ADDRESSES section of the direct final rule located in the rules section 
of this Federal Register.

FOR FURTHER INFORMATION CONTACT: Greg Crable, Environmental Protection 
Agency, Air Planning and Development Branch, 11201 Renner Boulevard, 
Lenexa, Kansas 66219 at (913) 551-7391, or by email at 
crable.gregory@epa.gov.

SUPPLEMENTARY INFORMATION: In the final rules section of the Federal 
Register, EPA is approving the state's SIP revision as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial revision amendment and anticipates no relevant adverse 
comments to this action. A detailed rationale for the approval is set 
forth in the direct final rule. If no relevant adverse comments are 
received in response to this action, no further activity is 
contemplated in relation to this action. If EPA receives relevant 
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 action. EPA will not institute a second comment 
period on this action. Any parties interested in commenting on this 
action should do so at this time. Please note that if EPA receives 
adverse comment on part of this rule and if that part can be severed 
from the remainder of the rule, EPA may adopt as final those parts 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: July 21, 2014.

Acting Regional Administrator, Region 7.
