What does the establishment number signify in the context of EPA regulations?

The establishment number is a crucial identifier in the context of EPA regulations, specifically relating to pesticide products. This number signifies the facility where the product was manufactured. Each establishment that produces a pesticide must be registered with the EPA, and the establishment number serves to trace back the source of the product, ensuring accountability and compliance with safety and regulatory standards. This helps in monitoring manufacturing processes and addressing any related safety concerns.

The other options, while related to various aspects of product regulation, do not accurately describe what the establishment number represents. The date of product approval is defined by the registration date established by the EPA, not indicated by the establishment number. The quantity of product produced could vary and is not inherently linked to the establishment number itself. Similarly, while the type of pesticide manufactured is important, it is not denoted by the establishment number, as this number specifically identifies the manufacturing location rather than the nature of the pesticide.
