Voluntary Clean Water Guidance for Agriculture

We've been working with an advisory group to research and write the Voluntary Clean Water Guidance for Agriculture. The guidance is a technical resource for agricultural producers that describes Ecology’s recommended best management practices (BMPs) to protect water quality. It is intended to support healthy farms while helping producers meet clean water standards. We plan to release 13 chapters of this guidance over the next two to three years. We want to give agricultural producers a comprehensive set of BMPs for protecting water quality. Please view our Guidance Focus Sheet to learn more.

Advisory Group

We established the Voluntary Clean Water Guidance for Agriculture Advisory Group to advise us on the identification and implementation of practices that support healthy farms and help farmers to meet clean water standards. We reached out to a wide range of stakeholders to find qualified candidates to be a part of the advisory group. Advisory Group members assist in the development of the guidance, provide review and feedback, and contribute to the guidance’s ultimate success.

More information on the how we will approach developing the guidance can be found in the Process Design document.
