The Department of Natural Resources seeks public comment on proposed amendments to Minn. R. 6120 and Minn. R. 4410, which govern the Mississippi River Corridor Critical Area (MRCCA). The amendments would establish districts within the MRCCA as well as minimum guidelines and standards for development within the districts. The proposed rules are also intended to provide for management of the MRCCA as a multi-purpose resource in a way that: conserves scenic, environmental recreational, mineral, economic, cultural, and historic resources and functions; maintains the river channel for transportation including barging and fleeting areas; provides for continuation and development of a variety of urban uses, including industrial, commercial, and residential; uses the river for water supply and receiving water for properly treated sewage, stormwater, and industrial waste effluents; and protects biological and ecological functions of the corridor. Comments are due March 22, 2010. http://www.comm.media.state.mn.us/bookstore/stateregister/34_24.pdf pp. 8484-49.
