are located in the docket, including the proposal notice and comments received on the 

proposed rulemaking so far, including requests for extension of the comment period. 

II. Background 

The purpose of this notice is to extend the public comment period on the EPA's 

recently proposed rulemaking titled, "State Implementation Plans: Response to Petition 

for Rulemaking; Findings of Substantial Inadequacy; and SIP Calls to Amend Provisions 

Applying to Excess Emissions During Periods of Startup, Shutdown, and Malfunction." 

The proposal was published in the Federal Register on February 22, 2013, with an 

original deadline of March 25, 2013, for receipt of comments. However, as provided in 

the proposal, because a public hearing on the proposal was requested and this hearing 

was held on March 12, 2013, the deadline for receipt of comments was automatically 

extended to 30 days after the date of the public hearing. Accordingly, the public comment 

period for the proposal has already been extended to April 11, 2013. 

The EPA has received numerous requests to extend the end date of the comment 

period for the proposed rulemaking beyond April 11, 2013. Those requesting additional 

time include industry, industry trade associations, and state and local air pollution 

agencies in potentially affected states. These requestors claim that because the proposal is 

complex and far-reaching, with unique state-specific issues, they need extra time during 

which to review existing SIP provisions in light of the proposed actions and to provide 

meaningful and comprehensive comments on all aspects of the proposal. 

The EPA has also received, to date, one request that it not extend the comment 

period for the proposed rulemaking. This request was from the environmental group that

submitted the petition at issue to the EPA. This requestor opposes requests to extend the 

comment period by an additional 60 to 90 days, given the seriousness of public health 

issues at stake and the already extended period of time it will take to address any 

necessary SIP revisions as a result of the proposed rulemaking, and because the 

justifications offered for extension of the comment period are not relevant to the specific 

issues in the rulemaking.

Findings of Substantial Inadequacy; and SIP Calls to Amend Provisions Applying to 

Excess Emissions During Periods of Startup, Shutdown, and Malfunction; Notice of 

Extension of Public Comment Period 

The EPA has carefully evaluated these competing requests regarding the length of 

the public comment period for the proposed rulemaking. In response to these requests, 

the EPA by this notice is extending the comment period for an additional 30 days, that is, 

until May 13, 2013. Accordingly, the EPA notes, commenters thus have a comment 

period of 80 days from the date the proposed rulemaking was published in the Federal 

Register and 89 days from the date the proposed rulemaking was posted on the EPA's 

website. The EPA believes that this length of comment period is reasonable and 

appropriate, considering the issues addressed in the proposed rulemaking.
