Generally, a person may apply manure 34 originating from an animal feeding operation on snow-covered 35 -2- LSB 2262XC (2) 86 da/rj 2/ 3

S.F. _____ or frozen ground, except during a period beginning in winter 1 and ending in early spring. However, an exception allows such 2 application if there is an emergency, the manure originates 3 from a small animal feeding operation, or if the manure is 4 injected or incorporated. The prohibition is enforced by the 5 department of natural resources. 6 TERMS. An “animal feeding operation” is a place where 7 animals (cattle, swine, horses, sheep, chickens, turkeys, 8 or fish) are confined for 45 or more days in a 12-month 9 period. A “confinement feeding operation” is an animal feeding 10 operation in which animals are confined in roofed areas (e.g., 11 buildings). A small animal feeding operation uses a formed 12 manure storage that has less than a 500 animal unit capacity 13 (e.g., 1,250 head of hogs weighing more than 55 pounds). 14 Injection is the process of applying manure beneath the soil 15 surface and incorporation is a process that mixes manure into 16 the soil. 17 APPLICABLE PENALTIES. A person who applies liquid manure 18 in violation of the bill’s prohibition would be subject to a 19 civil penalty, that may be administratively assessed by the 20 department, in an amount of not more than $10,000 (Code section 21 455B.109), or judicially assessed for an amount not more than 22 $5,000 per each day of the violation (Code section 455B.191). 23 Collected moneys would be deposited into the watershed 24 improvement fund (Code sections 459.603 and 466A.2). 25 -3- LSB 2262XC (2) 86 da/rj 3/ 3
