The Department of Agriculture and Rural Development will hold a public hearing to receive public  
comments on proposed changes to the Regulation no. 634. Commercial fertilizers rule set.  
The rules will allow the State of Michigan to align with current standards set by AAPFCO. The  
subsequent decrease in fertilizer usage and cost of tonnage reporting as a result of the proposed rule  
change benefits the public’s health, farmers, and the environment. The proposed rule change will benefit  
farmers and the industry by reducing the cost of tonnage reporting and decreasing the amount of  
fertilizer used. Both the public and environment will also see substantial benefits due to that decrease in  
fertilizer usage.  
By authority conferred on the director of the department of agriculture and rural development by section  
8516 of the natural resources and environmental protection act, 1994 PA 451, MCL 324.8516.  
The proposed rules will take effect 7 days after filing with the Secretary of State. The proposed rules are  
the Michigan Register. Copies of these proposed rules may also be obtained by mail or electronic mail at

Comments on these proposed rules may be made at the hearing, by mail, or by electronic mail at the
