So, you want to ship some material that has been determined to be a hazardous waste, do ya. You followed the EPA regulations to make your determination that you have a hazardous waste, and you will ship the waste to an EPA permitted and authorized Treatment, Storage and Disposal Facility (TSDF) for the proper treatment. But — another Federal Agency, the US Department of Transportation (USDOT or just DOT) will take precedence over the manner that the waste is shipped over the road. So you started by following EPA regulations in the determination and while the waste is on your site, then when you offer the waste for transport, the DOT regulations kick in. Once the waste is received at the TSDF, the EPA regulations govern the treatment of the waste.
