EPA reconsidering application exclusion zone with key amendments
The recently announced Spring 2024 regulatory agenda showcases an EPA proposed final rule that would reinstate certain requirements of the Agricultural Worker Protection Standard (WPS), particularly the reconsideration of the 2015 application exclusion zone (AEZ) amendments. If finalized, affected entities need to be aware of the proposed changes.
Proposed change #1: The area where the AEZ applies
Pesticide handlers must suspend applications if any worker or person, other than appropriately trained and equipped handlers involved in the application enters an AEZ, regardless of whether they are on or off the establishment.
Proposed change #2: The exception to application suspension requirements for property easements
Pesticide handlers must suspend applications if any worker or person, other than appropriately trained and equipped handlers involved in the application enters an AEZ, regardless of whether they are in an area subject to an easement.
Proposed change #3: The distances from the application equipment in which entry restrictions associated with ongoing pesticide applications apply
During pesticide application, the AEZ distance would be 100 feet for ground-based fine spray applications and a 25-foot AEZ for ground-based applications using medium or larger droplet sizes sprayed above 12 inches.
Potentially affected entities
If you work in or employ persons working in crop production agriculture where pesticides are applied, you may be potentially affected by this action. While not an exhaustive list, the applicability of this action may include the following North American Industrial Classification System (NAICS) codes:
- 111000 – Agricultural establishments
- 111421 – Nursery and tree production
- 113110 – Timber tract operations
- 113210 – Forest nurseries and gathering of forest products
- 11511, 115112, and 115114 – Farmworkers
- 115112 – Pesticide handling on farms
- 115115 – Farm labor contractors and crew leaders
- 115310 – Pesticide handling in forestry
- 325320 – Pesticide manufacturers
- 813311, 813312, and 813319 – Farmworker support organizations
- 813930 – Farmworker labor organizations
- 115112, 541690, and 541712 – Crop advisors
Regulatory history in brief
The original WPS regulation was enacted in 1992 under EPA’s Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to protect farm workers from pesticide exposures in production agriculture.
In 2015, EPA finalized various significant revisions to the 1992 WPS. Among those revisions was a new provision requiring agricultural employers to keep workers and all other individuals out of the AEZ during outdoor pesticide applications.
Five years later, in October 2020, EPA finalized improvements to the enforceability and workability of the AEZ requirements, which were to decrease regulatory burdens for farmers while maintaining critical worker protections. Two months later, petitions were filed challenging the rule, and a preliminary injunction was filed, which stayed the effective date of the 2020 rule.
Fast-forward to March 2023, when the EPA published a notice of proposed rulemaking that would reconsider the 2020 requirements. If finalized, it would reinstate some 2015 WPS AEZ requirements and retain certain 2020 AEZ rule provisions.
Key to remember: The EPA proposed rule will, if amended, reinstate previous AEZ requirements that are protective of public health and limit exposure to those who may be near ongoing pesticide applications.
