Biological Criteria for the Protection of Aquatic Life

Ohio EPA Supplemental Keys to the Larval Chironomidae (Diptera) of Ohio and Ohio Chironomidae Checklist, June 2007 [PDF 1,139K]

The following documents comprise supporting documentation for setting and using biological criteria in Ohio. All of the documents are needed to use the biological criteria, implement the field and laboratory procedures, and understand the principles behind their development, use, and application. Most of these documents have been scanned from the original documents dated 1988-9.
