Contrary to what some sales people would like you to believe, treatment technologies for nutrient management are not required for compliance with the new concentrated animal feeding operations rule.

At one point during rule development, treatment technologies were discussed as a requirement, says Deanne Meyer, nutrient management specialist at University of California-Davis. However, that provision was removed from the final rule. The same is true with obtaining cost-share funds — treatment technologies are not a requirement.

Treatment technologies can be a viable option, but they are not silver bullets.
