Part Four - Storing Pesticides

The Pesticide Storage: Regulatory Requirements and Guidelines (Schedule 1 & 2) document is a summary of the Environmental Protection and Enhancement Act (EPEA) regulatory requirements and operational guidelines for the safe display, storage and handling of pesticides and the management of pesticide releases. Details of the pesticide storage regulations are included in the Pesticide Sales, Handling, Use and Application Regulation.

The storage requirements and operational guidelines apply to anyone who stores Commercial and Restricted pesticides (pesticides listed in Schedules 1 and 2 of the provincial pesticide regulations). This document applies to pesticide wholesalers, retailers, warehouse distribution centres, custom pesticide applicators, and other pesticide services (includes government agencies and irrigation districts). It does not include storage of Domestic (lawn and garden) pesticides.

Alberta Environment and Parks will recognize a pesticide storage facility that meets the Agrichemical Warehousing Standards Association's (AWSA) warehousing standards as being registered. This is in the form of a valid AWSA Phase III Certification of Compliance indicating the facility has met provincial regulatory requirements.

Warehousing (commercial pesticide storage) of pesticides in Alberta (and across Canada) is a self-regulated industry initiative. The Agrichemical Warehousing Standards Association (AWSA) is the body that was formed in January of 1997 to manage standards, and is made up of representatives from various sectors (manufacturers, distributors, warehousers and governments). The objectives of the AWSA are to improve environmental protection, working conditions, and business risk through the establishment and implementation of warehousing standards.

Warehouses must be re-certified on a two-year cycle. The certification of approved warehouses is conducted by licensed auditors. For more information on AWSA, contact:

Mobile Storage

A mobile pesticide storage facility is a compartment used for storing pesticides for any period less than 90 days. The Mobile Pesticide Storage Guidelines apply to pesticide application operations that store pesticide on a vehicle or trailer (mobile or stationary) where the combined amount of pesticide in storage exceeds 10 litres (liquid) or 10 kilograms (dry).
