Asbestos Waste Shipment
A school abatement produces 180 bags of wet, friable asbestos debris and two 55-gallon drums of asbestos-contaminated sludge. The bags are single 6-mil, some torn and re-taped; the drums are open-top and not labeled. The contractor plans to load everything on a 20-foot stake-bed truck, cover it with a tarp, and drive 60 miles to a landfill that accepts asbestos by appointment. The driver has no hazardous-materials training, and the paperwork describes the load as 'construction debris.' The landfill requires asbestos waste to be containerized, labeled, and accompanied by a manifest; it does not accept liquid sludge. The abatement supervisor says the load is not hazardous because asbestos is a naturally occurring mineral. The shipment is scheduled for Friday afternoon.
1. Evaluate the packaging and labeling of the bags and drums. What must be corrected before transport?
Read the worked answer
The packaging is not acceptable as described. Torn, re-taped single bags can release fibers, and open, unlabeled drums are worse.
- Bags: torn bags should be placed inside intact overpack bags. Asbestos waste should be wet, sealed, and double-bagged or otherwise containerized so that no dust can escape. Each container should be labeled with the required asbestos warning and generator information.
- Drums: the drums must be closed and labeled. If the sludge is liquid, it may need solidification or a different permitted disposal route; the landfill has already said it does not accept liquid sludge.
- No visible dust: the outside of containers should be clean and free of debris.
- Do not overfill containers in a way that stresses seams or lids.
The supervisor's statement that asbestos is 'natural' is irrelevant to waste-handling requirements. The waste is regulated because of its form and fiber-release potential, not because it was manufactured.
2. Evaluate the proposed transport and paperwork. What transportation and manifest issues must be resolved?
Read the worked answer
Several issues must be resolved before the truck leaves:
- DOT status: friable asbestos waste may be regulated as a Class 9 hazardous material (UN2212). The contractor must make the DOT determination and, if regulated, provide hazardous-materials training, shipping papers, emergency response information, and any required labels or placards. A driver with no hazmat training is not acceptable for a regulated shipment.
- Vehicle: a stake-bed truck with a tarp may not provide adequate enclosure. The load should be in a closed vehicle or otherwise secured to prevent release; the tarp must not be the only barrier against fiber escape.
- Manifest: the paperwork cannot describe the load as 'construction debris.' It must identify the asbestos waste and the generator, and the landfill must receive its required manifest and appointment information.
- Landfill approval: the landfill must specifically accept the waste form. Liquid sludge is not acceptable there.
- No compaction of asbestos waste during transport or disposal unless the receiving facility specifically allows it with controls.
The shipment should not proceed on Friday until these issues are corrected.
3. What should be done with the torn bags and the liquid sludge?
Read the worked answer
The torn bags should be overpacked before they are moved. Do not simply re-tape a torn bag and load it; place it inside an intact, appropriately labeled bag or container, clean the outside, and then handle it as asbestos waste.
The liquid sludge should not be shipped to a landfill that does not accept liquids. Options include:
- Solidify the sludge with an absorbent or approved solidification method, if the receiving facility accepts the solidified form.
- Use a permitted treatment or disposal facility that is authorized to accept liquid asbestos-contaminated waste.
- Keep the drums closed and labeled in the meantime, and prevent leaks or spills.
Dumping or diluting the sludge is not acceptable. The generator should contact the landfill and the state solid-waste program to confirm the authorized route before any shipment. The manifest should be revised to reflect the actual waste form and destination.
