Approval and Promulgation of Air Quality Implementation Plan: Kentucky; Approval 

Section 110(a)(l) Maintenance Plan for the 1997 8-Hour Ozone Standard for the Paducah 

Area; Limited Reopening of Comment Period 

AGENCY: Environmental Protection Agency (EPA). 

ACTION: Proposed rule; limited reopening of the comment period. 

SUMMARY: EPA is announcing a 30-day reopening of the public comment period for 

the proposed rule entitled "Approval and Promulgation of Ah Quality Implementation 

Plan: Kentucky; Approval Section 110(a)(l) Maintenance Plan for the 1997 8-Hour 

Ozone Standard for the Paducah Area," for the purpose of limited public review and 

comment of supplemental information that was provided by the Commonwealth of 

Kentucky on July 15,2009, in support of the Paducah Area 1 lO(a)(l) maintenance plan. 

The Paducah, KY Area consists of Marshall and a portion of Livingston Counties. The 

proposed rule was initially published in the Federal Register on January 4,2010. The 

reason for this limited reopening of the comment period is that EPA has learned that 

supplemental information relating to projected emissions for the Paducah Area that was 

referenced in the proposed rulemaking January 4,2010 (75 FR 97) was inadvertently 

omitted from the electronic docket when that proposed rulemaking was published. EPA 

has since made that dormation available in the electronic docket and wants to ensure an 
opportunity for the public to comment on that information. The July 15, 2009 

supplemental information can be viewed online at www.reg~~lations.gov using docket ID 

No. EPA-RO~-OAR-~~~~- 1 186-0043. 

Thus, EPA is reopening the comment period for an additional thirty days, for the 

limited purpose of providing an opportunity for public comment on the supplemental 

information added to the docket after publication of the proposed rulemaking. 

DATES: The comment period for the proposed rule published on January 4,2010 (75 

FR 97), is reopened. Comments must be received on or before [Insert 30 days after 

publication].
