Several groups in IL - IL Beef Association, IL Farm Bureau, IL Milk Producers Assoc, and IL Pork Producers - came together to sponsor the Beef Resource Guide for cattlemen. The purpose of this guide is to explain how some of Illinois' environmental regulations apply to beef producers.
You can download the guide by clicking here.
I would highly suggest looking this guide over. If you have any questions, then there are several sources to seek guidance.
I hope you do find it helpful.
