40 CFR Part 52 

[EPA–R06–OAR–2008–0089; FRL–9132–2] 

Approval and Promulgation of 

Implementation Plans; Texas; 

Revisions to Voiding of Permits and 

Extension of Permits 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to approve 

severable portions of a submittal from 

the State of Texas, through the Texas 

Commission on Environmental Quality 

(TCEQ), on September 25, 2003, to 

revise the Texas Major and Minor New 

Source Review (NSR) State 

Implementation Plan (SIP). Within this 

SIP submittal, the State repealed a 

paragraph of the SIP rule pertaining to 

the Texas Major and Minor NSR SIP and 

renumbered the SIP rule’s paragraphs. 

We are proposing to approve the new 

replacement rule as meeting the Major 

and Minor NSR SIP requirements for 

voiding of permits. 

We are also proposing to approve the 

portion of the revision that addresses 

the recodification of the provision 

relating to the granting of one 18-month 

extension of a permit as meeting the 

Major and Minor NSR SIP requirement 

for extensions of permits. The revision 

imposes requirements on permitees, 

requiring a review of the permit’s 

underlying permit determinations 

before this SIP-approved extension can 

be granted. Finally, the revision 

provides for a second permit extension 

if certain conditions are met, including 

a health effects review. EPA is 

proposing to approve the new 

replacement rule for this second permit 

extension as meeting the Major and 

Minor NSR and NNSR SIP 

requirements. 

EPA finds that these changes to the 

Texas SIP comply with the Federal 

Clean Air Act (the Act or CAA) and EPA 

regulations, are consistent with EPA 

policies, and will improve air quality. 

This action is being proposed under 

section 110 and parts C and D of the 

Act. 

DATES: Comments must be received on 

or before May 3, 2010. 

ADDRESSES: Comments may be mailed to 

Mr. Jeff Robinson, Chief, Air Permits 

Section (6PD–R), 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 the Federal Register. 

FOR FURTHER INFORMATION CONTACT: If 

you have questions concerning today’s 

proposal, please contact Ms. Melanie 

Magee (6PD–R), Air Permits Section,

electronic mail at

SUPPLEMENTARY INFORMATION: In the 

final rules section of this Federal 

Register, EPA is approving the State’s 

SIP submittal as a direct final rule 

without prior proposal because the 

Agency views this as a noncontroversial 

submittal and anticipates no relevant 

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 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 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 the 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: March 24, 2010.

Acting Regional Administrator, Region 6.

Proposed Significant New Use Rule for 

1-Propene, 2,3,3,3-tetrafluoroAGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing a significant 

new use rule (SNUR) under section 

5(a)(2) of the Toxic Substances Control 

Act (TSCA) for the chemical substance 

identified as 1-Propene, 2,3,3,3- 

tetrafluoro- (CAS No. 754–12–1) which 

was subject to premanufacture notice 

(PMN) P–07–601. This proposed rule 

would require persons who intend to 

manufacture, import, or process the 

substance for an activity that is 

designated as a significant new use to 

notify EPA at least 90 days before 

commencing that activity. The required 

notification would provide EPA with 

the opportunity to evaluate the intended 

use and, if necessary, to prohibit or limit 

the activity before it occurs.
