(1-5) CommentsPage and Section Recommendations
1. Water body use designations (from relevant Water Quality Standards) are listed for waters in the planning area
3
Plan references 303(d) listings for lake, river, and for watershed through 1998.
p. iv, Executive Summary, ¶ 2; p. 5, MDEQ WQ Designation, last ¶ in section
Describe specific listings by water body at the time of initial planning and currently.
Scoring ExampleScoring ExampleScoring Key
1 incompleteA significant amount of additional information is needed to complete the section.
2 partially completeMost information has been included, but some additional information is needed to complete the section.
3 adequateThe section has adequate information and addresses the minimum criteria.
4 exceeds requirementsExceeds the minimum amount of information needed to address the criteria.
5 outstandingA significant amount of current, applicable, exceptional information is presented.
