Ohio EPA first introduced a water quality rule package in 2006 - intended to cover water quality standards, 401 certifications and antidegradation. The most recent reintroduction of that rule package was filed in December 2011, three days before Ohio's Common Sense Initiative (CSI) program was to take affect. The CSI program requires rules to undergo economic impact analysis. At industry request, the Ohio EPA Director pulled the rule package on February 1, 2012 and will refile them so they can go through the full CSI analysis. Here is the Ohio EPA Press Release.
