What’s in it

AI summary This bill adds shellfish to the list of animals used to calculate animal units for feeding operations. It divides shellfish into two weight categories to determine how they count toward a farm's total capacity. People who only raise shellfish in confinement operations can choose to follow general water quality rules instead of specific confinement feeding operation permits.1
