The Pollution Control Agency proposed to alter previous proposed amendments to Minn. R. 7050, 7052, and 7053, governing state water quality. Additional amendments expand the rule chapters affected and alter use classification for specific waters that support cold water communities (such as trout lakes). The deadline for comment is July 20, 2012. See http://www.comm.media.state.mn.us/bookstore/stateregister/36_47.pdf (pp. 1511-12).
