The Department of Natural Resources will conduct a public hearing to consider amendments to 10 CSR 20-7.031, Water Quality Standards. The Department of Natural Resources is amending subsection (2)(D) to create a reference to a new procedure developed to implement the antidegradation policy pursuant to 40 CFR 131.12. The state previously developed and promulgated an antidegradation policy in section (2) of this rule and is now proposing to incorporate into subsection (D) of this rule a reference to the implementation methods adopted by the Clean Water Commission on April 20, 2007. The hearing will be held March 12, 2008. Comments are due March 19, 2008. http://www.sos.mo.gov/adrules/moreg/current/2008/v33n2/v33n2b.pdf pp. 205-212.
