Q&A’s on Central Posting on 

Large or Non-contiguous 

Establishments 

The Agricultural Worker Protection Standard (WPS) is a regulation issued by the U.S. 

Environmental Protection Agency in 1992 and amended in 1995. 

used in the production of agricultural plants on farms, forests, nurseries, and greenhouses.

people seeking clarification on this part of the regulation, and have been answered by EPA’s 

Office of Compliance. 

What is required for central 

posting when an agricultural 

establishment is particularly 

large or has separate workforces 

on non-contiguous sites?

information) must be displayed in a 

central location on the agricultural 

establishment, in a place accessible to 

workers and handlers. EPA anticipated 

that there would be one central posting 

location on the agricultural 

establishment. 
However, if because of the size of the 

establishment or the separate nature of 

the workforce, there is not one central 

location that is accessible to all workers, 

then an employer will need more than 

one central posting to comply with the 

accessibility requirement in the rule. By 

accessible, EPA means that the 

information must be in a location where 

it can be readily seen and read and must 

be unrestricted in that it need not be 

requested. 

When an agricultural employer 

uses more than one central 

location on the agricultural 

establishment, what information 

may be provided at each 

location? 

The agricultural employer has two 

options. Option 1 is to post complete 

information for the entire establishment 

at all locations. Option 2 is to post 

information on applications made only 

to the part of the agricultural 

establishment served by the central 

location, if the following conditions are 

met: 

1. Each central location clearly 

indicates the area covered by the 

application list. The central posting 

states that it is site-specific and is 

only a partial listing of the 

applications on the establishment. 

The posting makes clear that there 

are other central locations. 

2. Any worker or noncommercial 

handler that enters any area of the 

agricultural establishment has been 

informed of the central location 

covering that area 

3. Each central location meets all 

other WPS requirements for a 

central location including display of 

a safety poster and emergency 

information. 

Note: If an agricultural employer has a 

central posting location displaying 

information about all applications, 

he/she may post site-specific information 

at other locations on the establishment. 

The above three conditions do not have 

to be met for this additional 

information.
