BACKGROUND

——

GENERAL.

Confinement

feeding

operations

are

21

regulated

by

the

department

of

natural

resources

(DNR)

under

22

the

“Animal

Agriculture

Compliance

Act”

(Code

chapter

459).

23

A

confinement

feeding

operation

is

a

type

of

animal

feeding

24

operation

in

which

agricultural

animals

are

maintained

for

at

25

least

45

days

in

any

12-month

period.

A

confinement

feeding

26

operation

is

an

animal

feeding

operation

in

which

animals

are

27

kept

in

a

structure

(building)

that

is

totally

roofed,

and

28

includes

any

associated

manure

storage

structure

(Code

section

29

459.102).

Generally,

a

confinement

feeding

operation

must

30

retain

manure

that

is

produced

at

the

location

in

a

manure

31

storage

structure

until

the

manure

is

transported

and

used

32

according

to

water

quality

requirements

(e.g.,

via

application

33

on

farmland)

(see

Code

section

459.311).

Regulations

governing

34

confinement

feeding

operations

vary

based

on

the

size

of

the

35

S.F.

2356

operation

measured

by

its

animal

unit

capacity

(AUC).

AUC

1

refers

to

a

measurement

used

to

determine

the

maximum

number

of

2

animal

units

that

may

be

maintained

as

part

of

a

confinement

3

feeding

operation

at

any

one

time.

In

calculating

AUC,

a

4

special

equivalency

factor

is

assigned

for

each

classification

5

of

confined

agricultural

animal.

A

confinement

feeding

6

operation

with

500

or

fewer

animal

units

(e.g.,

1,250

finishing

7

swine)

are

not

subject

to

the

same

level

of

regulation.

The

8

owner

or

operator

of

a

small

animal

feeding

operation

is

not

9

required

to

file

a

manure

management

plan

(MMP)

under

Code

10

section

459.312.

11

BACKGROUND

——

MMP.

Code

chapter

459,

subchapter

III,

12

regulates

water

quality,

including

the

discharge

of

manure

into

13

surface

water

sources

and

groundwater

sources.

Code

section

14

459.312

provides

for

the

of

an

MMP

to

DNR,

including

15

updates,

by

an

a

confinement

feeding

operation

or

a

16

person

who

applies

manure

from

a

confinement

feeding

operation

17

that

is

located

in

another

state,

if

the

manure

is

applied

on

18

land

located

in

this

state.

Generally,

an

MMP

must

include

19

information

regarding

where

and

how

much

manure

originating

20

from

a

manure

storage

structure

is

to

be

applied.

DNR

must

21

approve

the

MMP

according

to

procedures

established

by

DNR.

22
