Pretransport regulations are designed to ensure safe transportation of a hazardous waste from origin to ultimate disposal; to minimize the environmental and safety impacts of accidental releases; and to facilitate control of any releases that may occur during transportation. In developing these regulations, the EPA adopted those used by the Department of Transportation (DOT) for transporting hazardous materials (49 CFR 172, 173, 178 and 179). These DOT regulations require:
Proper packaging to prevent hazardous waste leakage under normal or potentially dangerous transport conditions such as when a drum of waste falls from a truck or loading dock; Labeling, marking, or placarding of the package to identify characteristics and dangers associated with the waste.
These pretransport regulations apply only to generators shipping waste off-site.
Briefly, individual containers are required to display "Hazardous Waste" markings, including the proper DOT shipping name, using the standardized language of 49 CFR Sections 172.101 and .102. The labels on individual containers must display the correct hazard class as prescribed by Subpart E of Part 172. Examples of DOT labels and placards are shown in Figures 11.10.1 and 11.10.2. Placards are important in case of accidents because they are highly visible. Efforts are now in progress for international adoption of hazardous marking, labeling and placarding conventions.
