Clean Water Guidance for Agriculture

We are developing the Voluntary Clean Water Guidance for Agriculture alongside the current Nonpoint Plan update. This guidance document is a technical resource for agricultural producers that recommends site-specific best management practices (BMPs) to protect water quality. It is intended to support healthy farms while helping producers meet clean water standards.

Chapters are developed using best available science and in coordination with our advisory groups including representatives from state agencies, Conservation Districts, agriculture producer groups, environmental organizations, and Tribal representatives. 

Once completed and submitted to EPA, the Voluntary Clean Water Guidance for Agriculture will consist of 14 chapters. We previously submitted five chapters to EPA and plan to submit the remaining eight chapters alongside the 2025 Nonpoint Plan Update.
