ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R06-OAR-2006-0885; FRL-9906-02-Region 6]

Approval and Promulgation of Air Quality Implementation Plans; 
Texas; Approval of Texas Motor Vehicle Rule Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing 
approval of revisions submitted by the State of Texas that affect the 
Texas State Implementation Plan (SIP) concerning Texas' motor vehicle 
air pollution rules. Based upon the State's submitted Texas clean fuel 
fleet (TCFF) program equivalency demonstration that the new Tier 2 and 
2007 heavy-duty diesel

vehicles and engines meet or exceed the LEV requirement, we are 
proposing to approve the removal of the TCFF program's repealed low 
emission vehicle (LEV) rules and mobile emission reduction credit 
(MERC) rules from the Texas SIP. We also are proposing to approve the 
removal of the Transportation Control Measures (TCM) substitution 
repealed rules from the Texas SIP. We are proposing to approve as part 
of the SIP, a new Texas Clean Fleet (TCF) program, with submitted 
revisions, to incentivize replacement of diesel vehicles and engines 
with alternatively fueled vehicles and engines, including hybrids.

DATES: Written comments must be received on or before March 3, 2014.

ADDRESSES: Comments may be mailed to Mr. Guy Donaldson, Chief, Air 
Planning Section (6PD-L), Environmental Protection Agency, 1445 Ross 
Avenue, Suite 1200, Dallas, Texas 75202-2733. 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: Mr. John Walser, Air Planning Section 
(6PD-L), Environmental Protection Agency, Region 6, 1445 Ross Avenue, 
Suite 700, Dallas, Texas 75202-2733, telephone (214) 665-7128; email 
address walser.john@epa.gov.

SUPPLEMENTARY INFORMATION: In the final rules section of this Federal 
Register, EPA is approving the State's SIP submittal 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 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. 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: January 15, 2014.

Regional Administrator, Region 6.
