Rule Information
The objective of the proposed rule is to update Wisconsin’s antidegradation policy and implementation procedures to establish an effective, transparent process for conducting antidegradation reviews consistent with federal regulations. Antidegradation reviews are a federally-required component of water quality standards. They are established to protect existing uses and to protect high quality waters from degradation. A state’s antidegradation policy and implementation procedures do not prohibit all activities that would otherwise lower water quality in high-quality waters. However, they require a demonstration that lowering of water quality is necessary to support social or economic development in the area where the waterbody is located.
States are required to adopt an antidegradation policy and implementation procedures that are consistent with the Clean Water Act and federal regulations promulgated under the Act (33 USC 1313(d)(4)(B), 40 CFR 131.12) and 40 CFR 132 Appendix E.
The purpose of these rule revisions is to ensure that Wisconsin’s antidegradation policy, currently established in ch. NR 102, Wis. Adm. Code, and its implementation procedures, detailed in ch. NR 207, Wis. Adm. Code, are consistent with federal regulations (40 CFR 131.12) that were revised effective August 21, 2015 (Federal Register Vol. 80, No. 162). The rule revisions may also include additional antidegradation policies and procedures that apply in the Great Lakes Basin (40 CFR 132, Appendix E).
