1.4 WPS: Covered Establishments, Notification & Training

WPS: Covered Establishments, Notification & Training

Why this matters: The Worker Protection Standard is the federal rule that reaches furthest into day-to-day agricultural work, and ODA enforces parts of it in Oregon. Start with who is covered, how workers and handlers differ, and what has to be posted at the central location before anyone sets foot in a treated field.

1. Worker Protection Standard (WPS, 40 CFR Part 170)

The Worker Protection Standard (WPS) is a federal regulation issued by the EPA under FIFRA to reduce the risk of pesticide poisonings and injuries among agricultural workers and pesticide handlers in farms, forests, nurseries, and greenhouses.

Core Agricultural Employer Duties under WPS

Agricultural employers carry strict legal responsibilities under 40 CFR Part 170. Compliance is enforced rigorously by the Oregon Department of Agriculture (ODA) and Oregon OSHA.

3. Dual Occupational Classifications & Minimum Age Standards

WPS establishes two distinct occupational groups with differing legal protections, training requirements, and operational duties.

│     • Tasks: Mixing, loading, transferring, applying, flagging for     │
│       aircraft, cleaning/repairing spray rigs, clearing clogged tips,  │
│       cleaning contaminated PPE, handling un-rinsed empty containers,  │
│       or entering treated areas during application or before REI ends. │
└────────────────────────────────────────────────────────────────────────┘

Mandatory Minimum Age Requirements

Under WPS regulations:

• Pesticide Handlers: Must be at least 18 years of age. No person under age 18 may mix, load, apply, flag, or handle open pesticide containers under any commercial circumstances.
• Early-Entry Workers: Any agricultural worker authorized to enter a treated area under a Restricted-Entry Interval (REI) to perform permitted early-entry tasks must be at least 18 years of age.
• Family Farm Exemption: The minimum age and certain administrative requirements are exempt strictly for immediate family members (spouses, parents, children, siblings) on wholly family-owned agricultural establishments. However, non-family hired employees are fully protected.

EPA-Approved Annual Safety Training

• Frequency: Training must be provided annually (every 12 months). The historical 5-year grace period was abolished under modernized WPS rules.
• Timing: Agricultural workers must receive EPA-approved worker training before entering any treated area where a pesticide has been applied or an REI has expired within the last 30 days. Handlers must be trained before performing any handling activity.
• Qualifications: Trainers must be certified applicators (Private or Commercial), state-designated WPS trainers, or individuals who completed an EPA-approved Train-the-Trainer course.
• Language & Materials: Training must be presented in a language understood by the employees, using EPA-approved training materials, manuals, or videos.
• Recordkeeping: Training verification logs (employee signature, date, trainer name, EPA approval number) must be retained by the employer for two (2) years.

4. Central Notification Site Architecture & Recordkeeping

Every agricultural employer must establish and maintain an unobstructed, easily accessible Central Notification Site located in an area where workers and handlers naturally congregate (e.g., main office, break room, primary assembly pad, central packing shed).

└────────────────────────────────────────────────────────────────────────┘

Required Fields on the Pesticide Application Information Log

The application log posted at the Central Notification Site must contain the following six specific legal data points:

1. Location and Description of the Treated Area: Specific field name, block number, GPS coordinates, or visual map designating the treated boundary.
2. Product Trade Name: The commercial brand name as printed on the EPA label.
3. EPA Registration Number: The complete federal registration number (e.g., EPA Reg. No. 12345-678).
4. Active Ingredient(s): The generic chemical common name(s) of all active ingredients in the product.
5. Application Timing: Exact date, application start time, and application completion/stop time.
6. Restricted-Entry Interval (REI): Total duration of the REI (hours/days) and the exact expiration timestamp (e.g., "Expires August 17 at 10:00 AM").
