EPA Proposes Rule to Update the Worker Protection Standard Pesticide Application Exclusion Zone Requirements
On October 24, 2019, the U.S. Environmental Protection Agency (EPA) announced that it is proposing narrow updates to the Worker Protection Standard’s (WPS) provision on the Application Exclusion Zone (AEZ) requirements. By narrowing updates to the WPS, EPA states that it will “improve the long-term success of the agency’s Application Exclusion Zone requirements” and “would improve enforceability for state regulators and reduce regulatory burdens for farmers.” EPA believes narrowing updates to the WPS will also continue to protect the health of farm workers and other individuals near agricultural establishments who could be exposed to agricultural pesticide applications. The proposed updates are consistent with the 2019 Pesticide Registration Improvement Act (PRIA).
EPA Administrator Andrew Wheeler states that EPA’s proposal “would enhance the agency’s Application Exclusion Zone provisions by making them more effective and easier to implement.” Wheeler states that “our proposal will make targeted updates, maintaining safety requirements to protect the health of those in farm country, while providing greater flexibility for farmers.”
EPA will hold a 90-day public comment period and seeks input on select updates that were publicly suggested to EPA by both state pesticide agencies responsible for enforcing the provision and agricultural stakeholders since the AEZ requirement was adopted in 2015. The proposed updates are also consistent with the U.S. Department of Agriculture’s comments during a May 2017 meeting of EPA’s Pesticide Program Dialogue Committee.
Specifically, EPA is proposing to:
Modify the AEZ so it is applicable and enforceable only on a farm owner’s property, where a farm owner can lawfully exercise control over employees and bystanders who could fall within the AEZ. As currently written, the off-farm aspect of this provision has proven very difficult for state regulators to enforce. These proposed changes would enhance both enforcement and implementation of the AEZ for state regulators and farm owners, respectively. Off-farm bystanders would still be protected from pesticide applications with the existing “do not contact” requirement that prohibits use in a manner that would contact unprotected individuals.
Exempt immediate family members of farm owners from all aspects of the AEZ requirement. This will allow farm owners and their immediate family members to decide whether to stay in their homes or other enclosed structures on their property during certain pesticide applications, rather than compelling them to leave even when they feel safe remaining.
Add clarifying language that pesticide applications that are suspended due to individuals entering an AEZ may be resumed after those individuals have left the AEZ.
Simplify the criteria for deciding whether pesticide applications are subject to the 25- or 100-foot AEZ.
Publication of the proposed rule in the Federal Register will begin a 90-day comment period.
When EPA included the AEZ concept in its 2015 WPS updates, of chief concern for pesticide applicators, farmers, and state departments of agriculture were the compliance and enforcement practicalities of aspects of the AEZ requirements. For example, in scenarios where the AEZ extends to nearby roads and highways, it is difficult for pesticide applicators to be aware of every vehicle that may pass by that could enter the AEZ during applications. It is unclear if the revised AEZ requirements adequately address these practical realities. Agricultural stakeholders and pesticide applicators may wish to submit comments on the proposed revisions.
