**40 CFR Part 52**

**[EPA–R03–OAR–2014–0759; FRL–9930–95– Region–3]** 

**Approval and Promulgation of Air Quality Implementation Plans; District**  **of Columbia, Maryland, and Virginia; 2011 Base Year Emissions Inventories**  **for the Washington, DC–MD–VA Nonattainment Area for the 2008**  **Ozone National Ambient Air Quality Standard** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) proposes to approve State Implementation Plan (SIP) revisions submitted by the District of Columbia, the State of Maryland, and the Commonwealth of Virginia (collectively, the States). The submittals are comprised of the 2011 base year carbon monoxide (CO) emissions inventories for the Washington, DC–MD–VA nonattainment area for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). In the Rules and Regulations section of this Federal Register, EPA is approving the States’ SIP submittals 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 and EPA’s Technical Support Document (TSD) prepared in support of this rulemaking action. The TSD is available in the Docket for this rulemaking action. If no adverse comments are received in response to this action, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

**DATES :**  Comments must be received in writing by August 24, 2015.

The petitioners request that NHTSA require underride guards on vehicles not currently required by the FMVSSs to have guards, notably, single unit trucks, and improve the standards’ requirements for all guards, including guards now required for heavy trailers and semitrailers.
