Through the 1970s, hazardous waste was often stored in drums outside, or just dumped and forgotten.
In 1980, a new federal law required hazardous waste to be carefully managed from “cradle to grave” -- or from generation to disposal.
When the hazardous waste program began, Ohio had 177 operating facilities that treated, stored and disposed of hazardous waste. Today, there are 34.
Newer technologies and waste reduction efforts helped reduce the need for so many hazardous waste facilities.
In addition, hundreds of sites where waste was dumped before environmental regulations existed have been cleaned up and put back into productive use.
