Where are hazardous waste manifests returned to in the state of Oklahoma?
Only uniform hazardous waste manifests documenting international shipments of hazardous waste or wastes generated by the DEQ need to be returned to the Oklahoma Department of Environmental Quality. All others sent to the DEQ will be recycled. Historical copies of manifests are stored in two locations. Manifests covering the period from 1977 to 1985 are stored in the Oklahoma State Archives located at the State Department of Libraries. Between 1985 and 1995 manifests are stored off site and may be reviewed at the convenience of the Land Protection Division. It will be necessary to make an appointment to review them. After 1995, DEQ was no longer required to collect manifests and they are not available at DEQ.
