It usually happens late. The excavation is open, the material is stockpiled, and the roll-off company you have used for years takes one look at the profile and says they cannot take it. Now the job is holding for disposal, and the people asking when it clears are not the people who understand why it stopped.
Special waste is any material that needs particular handling or permitting because of what it is chemically, physically, or biologically, or because of the risk it carries. Contaminated soil counts. So does spent blast media off a coating job. Most roll-off companies in San Antonio can take construction debris and nothing else, so when this material comes up, they have to pass.
The other version of this call comes earlier, from the procurement side. Someone is qualifying a hauler for a remediation scope and needs to see the actual registrations before the work is awarded. Either way, the question is the same one: can you legally take this, and can you prove it. Call 210-372-8666 and we will answer it on the first call.
One clarification worth making, because it comes up on nearly every qualification call. The Industrial and Hazardous Waste transporter registration carries the words "hazardous waste" because that is the name of the state program we are registered under. It is not a description of what we haul. We move non-hazardous material only, nothing above Class 2, and we will say so in writing.
The full set with context on each one is on our permits page. For a plain reading of what registered hauling actually changes on a job site, see our overview of EPA-registered waste hauling across South Texas.
