operation

where

10

agricultural

animals

are

maintained

for

at

least

45

days

in

any

11

12-month

period

and

includes

an

(operation)

and

any

associated

confinement

13

feeding

operation

with

16

a

rule

adopted

by

the

department

of

natural

resources

(DNR)

17

(Code

Generally,

of

an

operation

measured

by

its

animal

unit

capacity

19

(AUC).

For

purposes

of

quality

21

regulation,

more

animal

feeding

operations

under

common

22

ownership

or

management

are

deemed

to

be

a

single

operation

if

they

are

adjacent

or

utilize

a

common

24

system

for

manure

storage

and

are

separated

within

a

minimum

25

distance

from

each

other

based

on

the

of

the

operation.

For

purposes

of

regulation,

two

or

more

animal

27

feeding

operations

under

are

28

deemed

to

be

a

and

are

separated

by

another

set

of

separation

distances

based

on

the

size

of

the

operation.

BACKGROUND

——

AUC.

AUC

refers

to

a

measurement

used

to

33

determine

the

maximum

number

of

animal

that

may

be

10

or

(2)

they

The

operations

A

person’s

interest

is
