conversion

facilities.

29

The

bill

defines

on

when

an

33

aircraft

is

capacity

greater

than

100

kilowatts.

The

bill

requires

all

obstruction

lights

on

wind

energy

9

The

bill

further

requires

that

a

wind

energy

conversion

system

18

located

at

a

site

an

obstruction

light

controlled

by

an

19

terrain

limitations,

proximity

20

to

airports,

visual

ADLS.

22

The

bill

provides
