Non-household lead-bearing waste
Businesses, government agencies and schools may generate lead-bearing wastes from their daily operations or during remodeling and renovation.
- Non-household generators of lead-bearing waste must make a hazardous waste determination prior to disposal.
- Lead-bearing waste must be managed as either a solid waste or a hazardous waste depending upon the results of Toxicity Characteristic Leaching Procedure (TCLP) tests for lead.
- Wastes with 5.0 parts per million (ppm) or greater lead content by TCLP exhibit the toxicity characteristic for lead and must be managed as hazardous waste.
- Wastes with less than 5.0 ppm lead content by TCLP can be disposed of as regular solid waste.
- If the waste consistes of demolition debris, the appropriate way to collect samples for analysis is by coring a representative portion of the material to be disposed of (i.e., core through the wall, including both paint and wood).
- Because of the relatively small amount of lead present in the paint film on a wall, these wastes may not fail the TCLP test and can likely be disposed of as solid waste.
- If the material to be disposed of includes lead-based paint chips, sludge or blasting wastes, they will often fail the TCLP test because these wastes can concentrate lead.
- Wastes that fail the TCLP test must be disposed of at a hazardous waste disposal facility.
- Other lead-bearing wastes such as batteries and electronics should be recycled or must be disposed of as hazardous waste.
