Dear nutrient criteria stakeholders,

fyi - Bonnie Liscek at EPA sent me the following message concerning the necessity for developing nutrient criteria.

Several documents address the necessity for nutrient criteria          
development .  In the Clean Water Act, Section 303(c), states and      
authorized tribes are required to adopt criteria to protect designated  
uses that may be negatively affected by pollutants (such as nutrients).
The June 25, 1998 Federal Register stated that "EPA expects all States  
and Tribes to adopt and implement numerical nutrient criteria into      
their water quality standards by December 31, 2003". Geoffrey Grubbs'  
November 14, 2001 memorandum gives additional guidance about what is    
expected in the nutrient plan and criteria.  Attached is the nutrient  
criteria agreement letter between EPA and MDNR.  Links to the federal  
register and memorandum are as follows:
