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.

Read the full summary

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.
