AB842,1,2 1An Act to create 100.383 of the statutes; relating to: requiring bittering agents

Analysis by the Legislative Reference Bureau
This bill requires that engine coolant or antifreeze that is sold within this state
and that contains more than 10 percent ethylene glycol also contain, as a bittering
agent, denatonium benzoate in a concentration between 30 and 50 parts per million.
Under the bill, a manufacturer of such engine coolant or antifreeze must maintain
a record of the trade name, scientific name, and active ingredients of any bittering
agent used in the engine coolant or antifreeze, and must make the record available
to the public upon request.
The bill exempts a manufacturer, processor, distributor, recycler, or seller of an
engine coolant or antifreeze from liability for any personal injury, death, property
damage, environmental damage, or economic loss caused by the inclusion of
denatonium benzoate in the engine coolant or antifreeze, if the denatonium benzoate
is present in a concentration required in the bill. The provisions of the bill do not
apply to the sale of a motor vehicle that contains engine coolant or antifreeze or to
antifreeze sold in containers with a capacity of 55 gallons or more.
A person who violates the provisions of the bill is subject to up to 90 days
imprisonment, a fine up to $1,500, or both.

For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
