AEZ Proposed Revisions.

On March 13, 2019, EPA sent proposed revisions to the application exclusion zone (AEZ) provision of the WPS rule to OMB for review.  Following OMB review, EPA will send the proposed revisions to the appropriate congressional committees and USDA for review. These reviews are part of the FIFRA rulemaking process.

EPA is proposing to revise these regulations in response to input from members of the agricultural community, state pesticide regulatory agencies, and agricultural stakeholders.  EPA incorporated input obtained in part via EPA public outreach under Executive Order 13777, Enforcing the Regulatory Reform Agenda.  EPA’s proposal will be subject to a public notice and comment period.

January 9, 2019  EPA announces intent to leave designated rep and minimum age requirements in place; may amend AEZ in future
