Comment Period Extension Request on the Proposed Approval of the Illinois portion of St Louis, MO-IL area 8-hour Ozone Redesignation

Mr. Aburano, I write to request that EPA extend the comment period for this rulemaking docket (redesignation of Illinois Portion of the St. Louis Area to Attainment) for an additional 30 days. The current comment period begins today and runs for only 30 days, through the holiday season. The subject matter is complex and requires more time than 30 days for the public to have a meaningful opportunity to comment. Moreover, many agency staff who may need to be contacted for additional information to provide comments are out of the office for vacations during the next month. Therefore, I request that EPA extend the comment period for another 30 days, until February 23, 2012. Thank you for your consideration of this request. David C.
