OH HB96

Engine coolant and antifreeze manufactured after January 1, 2011, and sold in Ohio that contains more than 10% ethylene glycol must include denatonium benzoate as a bittering agent at a concentration of 30-50 parts per million.

Manufacturers and packagers must maintain records of the trade name, scientific name, and active ingredients of the bittering agent and provide this information to the public upon request.

Manufacturers, packagers, processors, distributors, recyclers, and sellers are prohibited from offering or distributing engine coolant or antifreeze in Ohio that does not comply with the bittering agent requirement.

Manufacturers, packagers, processors, distributors, recyclers, and sellers are immune from liability for personal injury, death, property damage, environmental damage, or economic loss resulting from the inclusion of denatonium benzoate in the required concentration.

The bittering agent requirement does not apply to engine coolant or antifreeze contained in new motor vehicles or wholesale containers of 55 or more gallons; violations are misdemeanors punishable by fines up to $1,000.
