WFP revisions occur when the farm’s water quality issues are not sufficiently addressed by the existing WFP. These shortcomings may be due to

• changes in the farm business (like the addition of livestock),
• the physical nature of the farm (like erosion caused by a 100-year flood event), or
• a failure of an existing BMP to adequately address an original issue.

The revision process is similar to that of the original WFP approval and implementation and may take time to execute. But ultimately, the planner and landowner work together to establish and maintain a flexible Whole Farm Plan, reviewed annually, that meets the growing and changing needs of the farm operation.
