If a CAO plan is disapproved, within how many days must it be resubmitted?

The correct answer is 30 days because the regulations concerning the approval processes for Concentrated Animal Operations (CAO) are designed to provide a specific timeline for resubmitting plans that have been disapproved. Within this 30-day period, the operator must address the reasons for disapproval and submit the revised plan to ensure compliance with nutrient management requirements.

This timeline ensures that improvements can be implemented promptly, helping to protect water quality and minimize environmental impacts due to nutrient runoff. Other potential time frames may not align with regulatory requirements or the urgency needed to promote responsible nutrient management practices in agricultural settings. By having a defined 30-day window, it encourages proactive management while still allowing for adequate time to make the necessary adjustments to the CAO plan based on the feedback received from the disapproval.
