7. Recommendations for Completing the Dioxin Reassessment To ensure that the final dioxin reassessment reflects the best available science, EPA should consider: Inviting the public to submit relevant data and studies now. Providing opportunities for the public comment on the charge to the SAB panel reviewing EPA’s Response to the NAS Report. Providing for public comment, peer review and IWG review of the draft dioxin reassessment. Requesting the Farm, Ranch and Rural Communities Federal Advisory Committee examine the impacts of the Dioxin Reassessment on agriculture, particularly on the Committee’s strategy for livestock operations. Establishing a public docket now for the Dioxin Reassessment and the interim PRGs to include all of the documents that the Agency is reviewing, or has reviewed, in conjunction with this effort.
