If you just got a soil test back and the results show contamination, the next call is to a hauler licensed to move it. In San Antonio and across South Texas, the license that matters comes from the Railroad Commission of Texas (RRC).
South Texas Dumpsters holds the Contaminated Soil Hauling License from the RRC, along with EPA ID TXR000083663, RRC Registration RN109046839, and the IHW Transporter license (SWR 96263).
Together, these credentials authorize hauling of class 1 and 2 non-hazardous special waste, including contaminated soil and sandblast material.
Contaminated soil shows up on San Antonio and Austin job sites more often than many contractors expect. Commercial properties being redeveloped into apartments, former gas station lots being repurposed, and utility trenching that cuts into historical fill are some of the work examples where contaminated soil could appear.
When the soil test comes back reading something other than clean fill, the project timeline depends on how fast the contractor can get the material off the site and properly disposed of.
The TCLP test (Toxicity Characteristic Leaching Procedure) is the gatekeeper. It identifies what is in the material and determines whether the waste is classified as class 1 non-hazardous, class 2 non-hazardous, or hazardous. A licensed hauler like South Texas Dumpsters can take class 1 and class 2 material. Anything above class 2 requires a specialized hazardous waste permit.
That classification drives two things at once: the disposal destination and the legal chain of custody. Moving contaminated soil without the right documentation is not a gray area. The exposure for using an unlicensed hauler usually runs back to the generator, meaning the contractor or property owner who produced the waste.
Not every waste hauling company can move contaminated soil. The license that matters most is the Contaminated Soil Hauling License, issued by the Railroad Commission of Texas (RRC). It specifically authorizes a company to transport contaminated soil under RRC oversight, the same agency that regulates oil, gas, and pipeline activity in Texas.
South Texas Dumpsters holds that license, along with an RRC Registration (RN109046839), an EPA ID (TXR000083663), and the IHW Transporter license (SWR 96263). The IHW Transporter credential authorizes hauling of industrial and hazardous-waste-classified non-hazardous materials, the category that covers contaminated soil, sandblast material, and similar special waste streams.
Together, these credentials let South Texas Dumpsters legally pick up contaminated soil, set up a waste profile, and deliver to a permitted disposal facility with documentation at every step.
A standard roll-off dumpster rental company without these credentials cannot legally accept contaminated soil. Some will take it anyway, and when something goes wrong in the disposal chain, the waste generator is the one who pays for it.
The Process from Soil Test to Cleared Site
The contaminated soil disposal process has a predictable flow once the license is in place:
If the TCLP results come back higher than class 2, South Texas Dumpsters cannot legally haul the material. A specialized hazardous waste transporter with additional federal credentials is required. We will walk you through finding an appropriately licensed hauler for the material and support the handoff, so the project keeps moving, rather than leaving you to figure out the next step alone.
For San Antonio and Austin contractors working on any project where contaminated soil may appear, the difference between an RRC-licensed hauler and a standard roll-off company shows up in the documentation.
An RRC-licensed hauler produces a disposal chain that is auditable. The waste profile, the transfer manifest, and the disposal facility receipt all tie back to the hauler’s credentials. If a regulator or environmental consultant later asks how contaminated soil from the site was handled, the contractor has paperwork to back it up. Without that, the contractor is left reconstructing the chain after the fact, often without the records to do it cleanly.
This matters most on projects where environmental due diligence is going to happen later: commercial property transactions, Phase I and Phase II ESA follow-ups, and redevelopment projects funded by sources that require compliance documentation. The paperwork needs to exist, and it needs to match what actually happened on the ground.
What does class 1 or class 2 non-hazardous mean for contaminated soil?
These are Texas state classifications for non-hazardous special waste that still require specific handling and disposal protocols. The TCLP test places the material into one of these classes based on the components identified. South Texas Dumpsters is licensed to haul class 1 and class 2 non-hazardous special waste, including contaminated soil. Material that exceeds class 2 classification is hazardous and requires a different hauler entirely.
What is a TCLP test and do I need one to dispose of contaminated soil?
The TCLP test (Toxicity Characteristic Leaching Procedure) is a laboratory test that identifies the components in contaminated soil and assigns it a waste classification. It is required before the material can be hauled. Without a test result, there is no classification, and without a classification, there is no legal path to disposal. If you do not have a testing partner lined up, South Texas Dumpsters can help arrange one.
How long does the contaminated soil disposal process take?
It depends on the site, the material, and the lab turnaround on the TCLP test. The fastest path is when the test is already done and the results are in hand. From that point, waste profile setup and scheduled hauling move quickly. If the test still needs to be run, add the lab turnaround time on top.
What happens if my contaminated soil test comes back as hazardous?
If the TCLP results show the material exceeds class 2 classification, it is categorized as hazardous waste and requires a specialized hazardous waste transporter. South Texas Dumpsters is not licensed to haul hazardous waste and will refer you to a partner who is.
If you are a contractor, site work manager, or commercial developer dealing with contaminated soil in San Antonio, Austin, or the surrounding South Texas region, South Texas Dumpsters has the credentials to move it legally and the process to move it quickly.
Call (210) 372-8666 to walk through your test results, your timeline, and the right container and disposal setup for your site. The South Texas Dumpsters team can help arrange TCLP testing if needed.
