The Air Pollution Control Board proposed to amend Tenn. Admin. Code §12.03.09, Construction and Operating Permits. Changes alter the requirements for a major source operating permit so that the greenhouse gas provisions no longer apply if the U.S. Court of Appeals for the D.C. Circuit or the U.S. Supreme Court determines that greenhouse gases should not be subject to regulation. There will be a public hearing on April 4, 2011. http://state.tn.us/sos/rules_filings/02-09-11.pdf.
