Treatment by Generator

On-site Treatment Requirements

In general, waste treatment is done at a treatment facility with a dangerous-waste permit. Under certain conditions generators may treat their own wastes on-site without a permit. When generators choose to treat their own waste, it is called treatment by generator or TBG. Treatment is done to make wastes less hazardous, non-hazardous, or easier/safer to transport. The basic conditions for on-site treatment are:

• Treat in an accumulation tank or container.
• Mark the tank or container with date waste is first added—empty every 90/180 days, depending on generator status.
• Maintain a log of treatment activity.
• Count and report amount of treated waste, and any dangerous waste residues resulting from treatment.

Additional published guidance documents refer to specific treatment methods:

Elementary Neutralization

Solidification

Evaporation

Filtration

Carbon adsorption

Separation and distillation
