Approval and Promulgation of Air 

Quality Implementation Plans; State of 

Colorado Second Ten-Year PM10

Maintenance Plan for Aspen 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing approval of 

the State Implementation Plan (SIP) 

revisions submitted by the State of 

Colorado. On May 25, 2011, the 

Governor of Colorado’s designee 

submitted to EPA a revised maintenance 

plan for the Aspen area for the National 

Ambient Air Quality Standards 

(NAAQS) for particulate matter with an 

aerodynamic diameter less than or equal 

to 10 microns (PM10), which was 

adopted by the State on December 16, 

2010. As required by Clean Air Act 

(CAA) section 175A(b), this revised 

maintenance plan addresses 

maintenance of the PM10 standard for a 

second 10-year period beyond the area’s 

original redesignation to attainment for 

the PM10 NAAQS. In addition, EPA is 

proposing approval of the revised 

maintenance plan’s 2023 transportation 

conformity motor vehicle emissions 

budget for PM10. This action is being 

taken under sections 110 and 175A of 

the CAA.

SUPPLEMENTARY INFORMATION: In the 

Rules section of this Federal Register, 

EPA is approving the State’s SIP 

revision through a direct final rule 

without prior proposal because the 

Agency views this as a noncontroversial 

SIP revision and anticipates no adverse 

comments. A detailed rationale for the 

approval is set forth in the preamble to 

the direct final rule. If EPA receives no 

adverse comments, EPA will not take 

further action on this proposed rule. If 

EPA receives adverse comments, EPA 

will withdraw the direct final rule and 

it will not take effect. Then, EPA will 

address all public comments in a 

subsequent final rule based on this 

proposed rule. EPA will not institute a 

second comment period on this action. 

Any parties interested in commenting 

must 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. See the information 

provided in the Direct Final action of 

the same title which is located in the 

Rules section of this Federal Register.

Approval and Promulgation of Air 

Quality Implementation Plans; 

Delaware; Attainment Plan for the 

Philadelphia-Wilmington, 

Pennsylvania-New Jersey-Delaware 

Nonattainment Area for the 1997 

Annual Fine Particulate Matter 

Standard 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed Rule; Supplemental. 

SUMMARY: EPA is issuing a supplement 

to its proposed approval of Delaware’s 

state implementation plan (SIP) 

published in the Federal Register on 

November 19, 2012. The SIP revision 

demonstrates Delaware’s attainment of 

the 1997 annual fine particulate matter 

(PM2.5) national ambient air quality 

standard (NAAQS) for the PhiladelphiaWilmington, Pennsylvania-New JerseyDelaware (PA–NJ–DE) PM2.5

nonattainment area. This supplemental 

proposal addresses the potential effects 

of a January 4, 2013 decision of the 

United States Court of Appeals for the 

District of Columbia Circuit (DC Circuit 

Court) remanding to EPA two final rules 

implementing the 1997 PM2.5 NAAQS 

on EPA’s proposed action. In addition, 

EPA is revising its proposed approval of 

Delaware’s attainment plan for the 1997 

annual PM2.5 NAAQS to not rely upon 

regulations which were part of the plan 

submitted by Delaware because they are 

not necessary to demonstrate 

attainment. Finally, EPA is proposing to 

approve the 2009 and 2012 motor
