and a Restricted Zone. Residents were allowed to go to the first two zones; access to the third zone was prohibited without authorization. By July 10, winds were no longer blowing dangerous substances and people were allowed to return to their homes, with the exception of two square miles in Miamisburg. The 300 families were restricted from that section, many housed at the city's high school. Parker said that while the fire was burning the city would try to dam Bear Creek in order to prevent the chemicals from spreading to the Great Miami River, a major source of drinking water. Throughout the period, in spite of efforts of firefighters, the fire at the accident site burned for days. The fire was not completely exhausted until July 12. Responses Senators John Glenn (Dem.) and Howard Metzenbaum (Dem.) asked president Ronald Reagan to order an investigation as to the accident's cause and the nation's policy for transporting hazardous substances. Gov. Celeste created the Ohio Hazardous Substance Emergency Team (OHSET) to investigate the derailment and to provide recommendations for improving protection of Ohio's citizens from threats from hazardous substances. On the conclusion of OHSET's investigation, on September 29, 1986, OHSET recommended the passing of legislation to fill in existing gaps in current regulations. The Cincinnati City Council on June 3, 1987, issued a resolution, stating it "urges the 117th General Assembly to enact H.R. 428, regulating the transportation of hazardous substances by truck and rail in Ohio, by requiring data concerning the specific nature of transported hazardous substances, prenotification of their transportation, advance route assessment, and providing for training for proper handling of said substance." Several class action lawsuits were filed. Already by July 10, a $200 million class action lawsuit was filed for four individuals. Eventually, in total, $450 million ($1,229,465,700 in 2023 dollars) in lawsuits were filed.
