          - 40 CFR Part 52
          - [EPA-R07-OAR-2017-0477; FRL-9967-94-Region 7]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from the State of Nebraska addressing the applicable requirements of Clean Air Act (CAA) section 110 for the 2010 Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS), and the 2012 Fine Particulate Matter (PM2.5) NAAQS, which requires that each state adopt and submit a SIP to support implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by EPA. These SIPs are commonly referred to as “infrastructure” SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. EPA is proposing approval of the infrastructure submissions as meeting the applicable requirements of CAA section 110, for all three submittals. EPA is proposing to approve elements of the 2010 NO2                         and SO2                         infrastructure SIP submissions from the State of Nebraska received on February 7, 2013, and August 22, 2013, respectively. EPA is also proposing to approve the 2012 PM2.5                         infrastructure submittal received on February 22, 2016. In the “Rules and Regulations” section of this                         **Federal Register**                        , we are approving the state's SIP revisions as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.

# SUPPLEMENTARY INFORMATION:

                    This document proposes to take action on the 2010 NO2                     and SO2                     NAAQS and the 2012 PM2.5                     NAAQS Infrastructure SIP submittals. We have published a direct final rule approving the State's SIP revision (s) in the “Rules and Regulations” section of this                     **Federal Register**                    , because we view this as a noncontroversial action and anticipate no relevant adverse comment. We have explained our reasons for this action in the preamble to the direct final rule. If we receive no adverse comment, we will not take further action on this proposed rule. If we receive adverse comment, we will withdraw the direct final rule and it will not take effect. We would address all public comments in any subsequent final rule based on this proposed rule. We do not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information, please see the information provided in the                     **ADDRESSES**                     section of this document.
