What defines a Concentrated Animal Operation (CAO)?

A Concentrated Animal Operation (CAO) is defined by a minimum of 8 Animal Equivalent Units (AEUs) alongside the stipulation of having more than 2 AEUs per acre of land. This definition is crucial in understanding the regulatory framework surrounding nutrient management and environmental protection.

In Pennsylvania, the CAO designation is important because it helps to identify operations that are large enough to potentially contribute significantly to nutrient runoff and other environmental concerns. The specific threshold of 8 AEUs establishes a baseline for operations that engage in concentrated animal feeding, warranting scrutiny regarding their nutrient management practices. Additionally, the requirement of having more than 2 AEUs per acre emphasizes the density of animal units in relation to the available land, which is pivotal for assessing potential environmental impact and ensuring sustainable agricultural practices.

Recognizing CAOs is fundamental for implementing appropriate nutrient management plans, ensuring that these operations adhere to regulations designed to mitigate water pollution and promote responsible livestock management.
