This rulemaking would remove the domestic quarantine regulations for the plant pest emerald ash borer. This action would discontinue the domestic regulatory component of the emerald ash borer program as a means to more effectively direct available resources toward management and containment of the pest. Funding previously allocated to the implementation and enforcement of these domestic quarantine regulations would instead be directed to a non-regulatory option of research into, and deployment of, biological control agents for emerald ash borer, which would serve as the primary tool to mitigate and control the pest.
