The deadline for comments on the EPA proposed rule (CWA) has been pushed back to October 20, 2014: http://www.regulations.gov/#!documentDetail;D=EPA-HQ-OW-2011-0880-2733
Looking over comments posted so far this indeed is going to be a contentious issue. According to Regulations.gov there are 3,154 public postings to date divided for and against the rule. Also a number of the comments asked for the extended deadline in order to gain more time for evaluation.
