Effective manure management at large livestock operations helps keep nitrates, harmful bacteria, excess nutrients and other pollutants out of surface and ground water. The Department of Ecology is proposing updates to the Concentrated Animal Feeding Operation (CAFO) water quality permit, which is how the agency oversees manure management at certain facilities.
As part of the five-year permit review cycle, Ecology is asking for feedback on revisions to this permit, which mostly applies to large dairies. A number of the proposed updates are in response to a 2021 decision from the Washington State Court of Appeals, following appeals to an earlier version of the permit.
Currently, 24 CAFOs are regulated under Ecology’s permit, out of more than 100 large CAFO facilities in the state. Ecology regulates these facilities because they have either released waste that entered surface or ground water, or they voluntarily chose to come under the permit.
"Large livestock operations must effectively manage their manure to protect drinking water, shellfish resources, and fish-bearing streams," said Vince McGowan, Ecology’s Water Quality Program Manager. "We are committed to continuing to work with livestock owners and stakeholders to ensure these facilities are using best practices to prevent pollution."
The Washington State Department of Agriculture is the principal inspector of dairies and partners with Ecology to implement this permit.
The proposed revisions are based on Ecology’s experience implementing the current permit, including inspections and enforcement actions, updated science, permit appeal decisions, and stakeholder feedback.
Ecology initially planned to propose updates to the permit in the summer of 2021, when a ruling from the Court of Appeals on the permit was issued. The agency determined it made sense to incorporate the ruling in the draft permit and hold another round of listening sessions prior to releasing the draft permit for public review.
Based on the 2021 Court of Appeals decision, Ecology is proposing a number of updates, including:
In addition, Ecology is proposing changes to a few areas of the permit:
Ecology is also proposing to start online reporting for this permit, so the information Ecology collects from permittees, such as annual reports, is available immediately. Previously, all permit documents were submitted to Ecology on paper.
Draft permit language and SEPA documents are available for public comment until Aug. 17, 2022. Ecology has planned two public hearings on the permit, where attendees can hear a presentation from Ecology and provide verbal comments if they choose. Spanish language interpretation will be available at both events.
