GENERAL.

This

bill

provides

for

the

regulation

of

a

1

community

anaerobic

digester

system

(system)

by

the

department

2

of

natural

resources

(DNR)

which

must

include

a

digester

3

processing

structure

that

primarily

processes

manure

but

may

4

also

process

other

organic

feedstocks.

The

system

produces

5

a

biogas

which

is

a

source

of

renewable

fuel

and

a

digestate

6

which

is

a

nutrient-rich

material

that

may

be

applied

to

7

cropland.

8

TERMINOLOGY.

The

bill

provides

for

the

regulation

of

9

off-farm

systems.

“On-farm”

refers

to

real

property

used

to

10

produce

agricultural

animals

or

crops

as

compared

to

“off-farm”

11

which

refers

to

real

property

other

than

on-farm.

Once

12

manure

or

feedstock

is

received

by

the

system,

the

manure

is

13

referred

to

as

digester

manure

and

the

feedstock

is

referred

14

to

as

digester

feedstock.

The

off-farm

system

receives

15

on-farm

manure

and

either

on-farm

or

off-farm

feedstock.

The

16

digester

manure

or

digester

feedstock

is

subject

to

storage

17

requirements.

Different

regulations

apply

to

digester

18

feedstock

or

digester

manure

that

is

dry

or

liquid.

Digester

19

manure

or

digester

feedstock

is

classified

as

dry

only

if

the

20

digester

manure

or

digester

feedstock

does

not

flow

perceptibly

21

under

pressure,

is

not

capable

of

being

transported

through

22

a

mechanical

pumping

device

designed

to

move

a

liquid,

and

23

consists

of

molecules

that

do

not

flow

freely

among

themselves.

24

Generally,

liquid

digester

manure

and

liquid

digester

feedstock

25

must

be

stored

in

a

liquid

digester

storage

structure.

Dry

26

digester

manure

or

dry

digester

feedstock

must

be

stored

as

27

a

dry

digester

stockpile

or

in

a

liquid

digester

storage

28

structure.

The

digester

manure

or

digester

feedstock

is

used

29

by

a

digester

processing

structure

to

produce

biogas

and

a

30

digestate.

A

digester

processing

structure

must

process

manure

31

as

its

primary

source.

Digestate

is

also

referred

to

as

dry

32

or

liquid

based

on

the

same

criteria

used

for

digester

manure

33

and

digester

feedstock.

Liquid

digestate

is

stored

in

a

liquid

34

digestate

storage

structure

and

dry

digestate

is

stored

as

a

35

stockpile

or

a

liquid

structure.

The

1

scope

of

the

bill

is

limited

to

the

off-farm

construction,

2

including

expansion,

of

digester

structures

on

the

site

of

the

3

system,

the

off-farm

stockpiling

of

dry

digester

manure

or

4

feedstock

on

the

site

of

the

system,

the

off-farm

storage

and

5

stockpiling

of

digestate

on

the

site

of

the

system,

the

removal

6

of

the

digestate

from

the

off-farm

site

of

the

system,

and

7

the

on-farm

storage

and

application

of

the

removed

digestate.

8

Any

reference

in

the

bill

to

a

digester

structure

means

a

9

covered

liquid

digester

storage

structure,

a

covered

digester

10

processing

structure,

or

a

covered

liquid

digestate

storage

11

structure.

Any

reference

to

a

digester

stockpile

refers

to

a

12

dry

digester

manure

or

feedstock

stockpile

or

a

dry

digestate

13

stockpile.

14

REGULATION.

The

bill

provides

that

a

system

cannot

be

15

identified

with

an

animal

feeding

operation

where

animals

are

16

confined

and

fed

and

maintained

for

45

days

or

more

in

any

17

12-month

period.

Identification

occurs

only

if

the

system

18

and

the

animal

feeding

operation

are

both

(1)

under

common

19

ownership

or

management

and

(2)

adjacent.

20

CONSTRUCTION.

The

bill

provides

that

a

construction

21

permit

must

be

issued

by

DNR

prior

to

the

construction

22

of

a

digester

structure.

The

requirements

for

a

permit

23

are

based

on

permit

requirements

for

the

construction

of

24

manure

storage

structures.

The

application

must

include

an

25

engineering

report,

construction

plans,

and

specifications

26

prepared

by

a

professional

engineer.

The

bill

provides

27

for

an

application

fee

not

to

exceed

$1,000.

The

bill

also

28

provides

for

construction

design

standards

for

a

formed

29

or

unformed

digester

structure.

The

construction

design

30

standards

must

be

based

on

uniform

standards

such

as

available

31

standards

promulgated

by

ASTM

(American

society

for

testing

and

32

materials)

international.

The

design

standards

for

unformed

33

digester

feedstock

storage

structures

must

account

for

the

use

34

of

linings

and

erosion

controls.
