EXPLANATION

The

inclusion

of

this

explanation

not

constitute

agreement

the

explanation’s

substance

by

members

of

general

assembly.

21

BACKGROUND.

An

animal

feeding

operation

(AFO)

is

regulated

22

under

several

Code

chapters,

including

Code

chapter

455B,

23

subchapter

III,

governing

water

quality,

and

Code

chapter

459,

24

subchapter

III,

governing

all

AFOs,

which

includes

provisions

25

regulating

confinement

feeding

operations,

and

Code

chapter

26

459A,

which

includes

selected

provisions

regulating

open

27

feedlot

operations.

The

Code

chapters

are

administered

and

28

enforced

by

the

department

of

natural

resources

under

the

29

oversight

of

the

environmental

protection

commission

(EPC)

30

(Code

chapter

455A).

31

BACKGROUND

——

ANIMAL

FEEDING

OPERATIONS.

An

AFO

is

an

area

32

in

which

agricultural

animals

are

confined

for

45

days

or

more

33

in

any

12-month

period,

and

all

associated

structures

used

34

for

the

storage

of

manure.

feeding

operation

35

maintains

animals

in

roofed

buildings

and

stores

liquid

manure

1

in

a

formed

or

unformed

structure

(see

Code

section

459.102).

2

An

open

feedlot

operation

is

an

unroofed

or

partially

roofed

3

facility

without

crop,

vegetation,

or

forage

growth

or

residue

4

cover

(Code

section

459A.102).

Manure

from

an

open

feedlot

5

operation

includes

solids

and

effluent

that

are

usually

not

6

stored

in

a

structure

associated

with

a

confinement

feeding

7

operation.

8

BACKGROUND

——

STATE

AND

FEDERAL

LAW.

Both

Code

chapters

459

9

and

459A

regulate

the

application

of

manure

and

other

effluent

10

originating

from

an

operation,

including

application

close

11

to

water

sources.

AFOs

are

also

regulated

under

federal

law

12

by

the

United

States

environmental

protection

agency,

which

13

administers

and

enforces

the

national

pollutant

discharge

14

elimination

system

program

(NPDES

program)

pursuant

to

the

15

federal

Water

Pollution

Control

Act

of

1972

(33

U.S.C.

ch.

26,

16

as

amended,

and

40

C.F.R.

pts.

122

and

412).

EPA

contracts

17

with

DNR

to

administer

and

enforce

the

NPDES

program.

Under

18

the

NPDES

program,

AFOs

are

referred

to

as

concentrated

animal

19

feeding

operations

(CAFOs).

The

purpose

of

both

state

and

20

federal

regulation

is

to

prevent

manure

or

effluent

from

21

contaminating

groundwater

and

surface

water.

In

compliance

22

with

federal

law,

manure

from

a

CAFO

cannot

be

disposed

of

23

or

discharged

in

a

manner

that

will

cause

surface

water

or

24

groundwater

pollution

(Code

section

459.311).

However,

in

all

25

cases

involving

the

disposal

of

manure

and

effluent

originating

26

from

an

AFO,

rules

adopted

by

the

EPC

can

be

no

more

stringent

27

than

federal

law

(Code

sections

455B.173,

459.311,

and

28

459A.401).

29

BILL’S

PROVISIONS.

This

bill

eliminates

provisions

that

30

prevent

EPC

rules

regulating

manure

or

effluent

originating

31

from

an

AFO

from

being

more

stringent

than

federal

law.

The

32

bill

provides

that

the

NPDES

program

establishes

minimum

33

requirements.

The

EPC

is

required

to

adopt

rules

that

provide

34

more

restrictive

requirements

as

necessary

to

regulate

the

storage,

treatment,

and

application

of

manure

and

other

1

effluent

originating

from

an

AFO

in

a

manner

that

preserves

and

2

enhances

water

quality

in

the

state.

The

bill

also

eliminates

3

provisions

that

exempt

EPC

rules

regulating

AFOs

from

being

4

subject

to

the

ordinary

periodic

comprehensive

administrative

5

review

of

agency

rules

(Code

section

17A.7(2)

or

(3)).

6

APPLICABLE

PENALTIES.

A

person

who

is

in

violation

of

the

7

bill’s

provisions

is

subject

to

a

civil

penalty

under

Code

8

chapter

459

or

459A.

A

person

who

violates

Code

chapter

459,

9

subchapter

III,

is

subject

to

the

administrative

assessment

of

10

a

civil

penalty

of

up

to

$10,000

for

each

day

of

a

violation

11

(Code

section

459.603

referring

to

Code

section

or

12

the

judicial

assessment

of

a

civil

of

up

to

for

13

each

day

of

a

violation

(Code

section

459.603

referring

to

Code

14

A

person

who

violates

same

judicial

assessment

(Code
