EXPLANATION

28

The

inclusion

of

this

explanation

does

not

constitute

agreement

with

29

the

explanation’s

substance

by

the

members

of

the

general

assembly.

30

BACKGROUND

——

GENERAL.

Confinement

feeding

operations

31

are

regulated

by

the

department

of

natural

resources

(DNR)

32

under

the

“Animal

Agriculture

Compliance

Act”

(AACA)

(Code

33

chapter

459).

A

confinement

feeding

operation

is

a

type

of

34

animal

feeding

operation

in

which

agricultural

animals

are

35

-3-

LSB

6633XS

(5)

91

da/js

3/

5

S.F.

2260

maintained

for

at

least

45

days

in

any

12-month

period.

A

1

confinement

feeding

operation

is

an

animal

feeding

operation

2

in

which

animals

are

kept

in

a

structure

(building)

that

is

3

totally

roofed,

and

includes

any

associated

manure

storage

4

structure

(Code

section

459.102).

Generally,

a

confinement

5

feeding

operation

must

retain

manure

that

is

produced

at

the

6

location

until

the

manure

is

transported

and

used

according

to

7

water

quality

requirements

(e.g.,

via

application

on

farmland)

8

(see

Code

section

459.311).

Regulations

governing

confinement

9

feeding

operations

vary

based

on

the

size

of

the

operation

10

measured

by

its

animal

unit

capacity

(AUC).

AUC

refers

to

11

a

measurement

used

to

determine

the

maximum

number

of

animal

12

units

that

may

be

maintained

as

part

of

a

confinement

feeding

13

operation

at

any

one

time.

In

calculating

AUC,

a

special

14

equivalency

factor

is

assigned

for

each

classification

of

15

confined

agricultural

animal.

A

confinement

feeding

operation

16

with

an

AUC

of

1,000

or

more

animal

units

(e.g.,

2,500

17

swine

weighing

55

or

more

pounds)

must

be

issued

a

permit

to

18

construct

or

expand

a

confinement

feeding

operation

structure.

19

BACKGROUND

——

COUNTY

PARTICIPATION.

A

county

board

of

20

supervisors

(board)

is

prevented

from

adopting

a

county

zoning

21

ordinance

that

applies

to

land

and

structures

associated

22

with

agricultural

production

(Code

section

335.2).

A

board

23

is

also

preempted

from

exercising

county

home

rule

authority

24

over

the

regulation

of

animal

feeding

operations

(Code

section

25

331.304A),

Under

the

AACA,

a

board

may

formally

evaluate

26

the

siting

of

a

confinement

feeding

operation

structure

27

(Code

section

459.304).

The

board

must

adopt

a

construction

28

evaluation

resolution.

Under

the

resolution,

the

board

29

applies

a

master

matrix

in

which

the

board

scores

criteria

30

relating

to

the

construction

of

a

confinement

feeding

operation

31

structure

as

specified

in

a

permit

application

to

DNR.

The

32

board

may

submit

an

adopted

recommendation

to

DNR

to

approve

33

or

disapprove

the

application.

The

board

may

also

submit

34

comments

regarding

the

management

of

manure

incorporated

into

1

BILL’S

PROVISIONS.

This

bill

enacts

a

provision

in

Code

2

chapter

459,

subchapter

III,

which

regulates

water

quality

3

(see

Code

section

459.311).

The

bill

provides

that

a

county

4

may

adopt

a

confinement

feeding

operations

siting

ordinance

5

(ordinance)

that

allows

a

board

to

approve

the

site

of

the

6

construction

or

expansion

of

a

confinement

feeding

operation

7

structure

that

would

be

part

of

a

confinement

feeding

operation

8

that

has

an

AUC

of

1,000

animal

units

or

more.

The

ordinance

9

authorizes

the

board

to

place

conditions

on

site

approval

or

10

the

application

of

manure

originating

from

the

confinement

11

feeding

operation.

The

bill

provides

that

the

ordinance

12

may

establish

separation

distance

requirements

between

a

13

confinement

feeding

operation

structure

and

a

benefited

object

14

or

location

that

is

greater

than

required

by

the

AACA

(Code

15

section

459.202

governing

air

quality).

The

bill

provides

that

16

the

county

may

adopt

the

ordinance

notwithstanding

provisions

17

in

Code

sections

331.2

and

331.304A.
