Notice of reopening of public comment period.


The EPA is announcing the reopening of the public comment period for the EPA's responses to state and tribal designation recommendations for the 2010 Sulfur Dioxide National Ambient Air Quality Standard. The EPA sent the responses directly to the states and tribes on or about February 7, 2013. On February 15, 2013, the EPA published a notice of availability in the Start Printed Page 17916 Federal Register that the EPA had posted the responses on its Internet Web site and the EPA invited public comment. In the notice of availability, the EPA stated that public comments must be received on or before March 18, 2013. The EPA has received several requests from stakeholders for additional time to prepare their comments. Some of the requesters asserted that they needed additional time to review the EPA's response to state's proposed designation and prepare their responses due to the complexity of the issues impacting their area. Taking that into consideration, the EPA is reopening the comment period until April 8, 2013. The EPA intends to make final the designation determinations for the areas of the country addressed by these responses in June 2013.


Comments on the notice of availability published February 15, 2013 (78 FR 11124) must be received on or before April 8, 2013. Please refer to SUPPLEMENTARY INFORMATION for additional information on the comment period.
