A bill to amend the Petroleum Marketing Practices Act to require retail gasoline dispensing devices to post health hazard warning labels informing the consumer of the presence of elevated levels of benzene.

Amends the Petroleum Marketing Practices Act to make it unlawful for any petroleum refiner or manufacturer to introduce into retail commerce motor fuels containing either benzene, toluene, or xylene. Sets forth permissible levels of naturally occuring benzene, toluene, or xylene.

Permits petroleum fuel manufacturers or refiners to introduce into retail commerce such additives at levels exceeding the permissible if the retail dispensing pump prominently displays a warning of the health dangers posed by exposure to such additives. Prescribes: (1) the size and content of such labeling information; and (2) the testing procedure for the benzene content of motor fuels.
