Revisions to Federal Implementation 

Plans To Reduce Interstate Transport 

of Fine Particulate Matter and Ozone 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing additional 

revisions to certain portions of the 

Transport Rule (Federal Implementation 

Plans: Interstate Transport of Fine 

Particulate Matter and Ozone and 

Correction of SIP Approvals, published 

August 8, 2011). The final Transport 

Rule limits the interstate transport of 

emissions of nitrogen oxides (NOX) and 

sulfur dioxide (SO2) that contribute 

harmful levels of fine particle matter 

and ozone in downwind states. After the 

final rule was published, it was brought 

to our attention that there are some 

incorrect data assumptions that affect a 

few states’ budgets or new unit setasides in the rule text. On October 14, 

2011, EPA proposed revisions to the 

final Transport Rule based on this new 

information and sought comment on 

additional unit-level information 

addressing post-combustion pollution 

control equipment and operational 

requirements necessitating noneconomic generation of a unit. EPA is 

finalizing the earlier specifically 

proposed revisions in a separate action. 

EPA has reviewed the information 

provided in comments addressing the 

topics described above and proposes to 

determine that the unit-level 

adjustments described in the preamble 

to the direct final are merited. 

DATES: Written comments must be 

received by March 22, 2012. 

ADDRESSES: Submit your comments, 

identified by Docket ID No. EPA–HQ– 

OAR–2009–0491, by mail to: Air and 

Radiation Docket and Information

submitted electronically or through 

hand delivery/courier by following the 

detailed instructions in the ADDRESSES

section of the direct final rule published 

elsewhere in this issue of the Federal 

Register.

SUPPLEMENTARY INFORMATION: This 

document proposes to take action on 

certain portions of the Transport Rule. 

We finalized a rule to address 

discrepancies in unit-specific modeling 

assumptions that affect the proposed 

calculation of Transport Rule state 

budgets in Florida, Louisiana, Michigan, 

Mississippi, Nebraska, New Jersey, New 

York, Texas and Wisconsin, as well as 

new unit set-asides in Arkansas and 

Texas (see 76 FR 63860, October 14, 

2011). We are issuing a direct final rule, 

in parallel with this proposal published 

elsewhere in this issue, based on 

comments received on the Revisions 

Rule proposal, to amend the August 8, 

2011, final regulation (76 FR 48208) by 

correcting annual NOX budgets in 

Georgia, Kansas, Missouri, New York, 

Ohio, and Texas; ozone-season NOX

budgets in Arkansas, Georgia, Louisiana, 

Mississippi, Missouri, New York, Ohio, 

Oklahoma, and Texas; SO2 budgets in 

Georgia, Indiana, Kansas, Nebraska, 

New York, Ohio, and South Carolina; 

and new unit set-aside budgets in 

Arkansas, Louisiana, and Missouri. 

We have explained our reasons for 

this action in the preamble to the direct 

final rule. If we receive no significant 

adverse comment, on the direct final 

rule, EPA will withdraw the relevant 

portions of the rule and timely notice of 

the withdrawal will be published in the 

Federal Register. We would address all 

relevant 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. 

Dated: February 7, 2012.

Administrator.
