Dairy Farm Best Management Practices

01. BMPs. Each dairy farm subject to Sections 760 through 764, or that otherwise obtains a permit by rule under these sections, must employ BMPs for the control of ammonia to total twenty-seven (27) points. Points may be obtained through third party export with sufficient documentation. The table located at Subsection 764.02. lists available BMPs and the associated point value. As new information becomes available or upon request, the Department may determine a practice not listed in the table constitutes a BMP and assign a point value. (3-28-23) 02.
