Hazardous Waste Generator Requirements

If you produce a waste that is hazardous, you are a hazardous waste generator. As a business owner, it is important to know whether you generate a hazardous waste. First you must know when a material becomes a waste. Generally, a waste is any discarded material that is not excluded by rule or other legal mechanisms. If you have a material that you can no longer use, it is probably a waste. Not all wastes that are recycled are exempt from regulation.

Any person who generates a waste (other than a household) must determine if the waste meets the definition of a hazardous waste. If the waste is hazardous, the generator must store, treat, transport and dispose of their hazardous waste, according to Ohio’s hazardous waste rules.

For help determining if you generate hazardous waste, these guidance documents will be helpful:

Hazardous Waste Generator Categories

The requirements a generator must comply with depends on the amount of hazardous and acute hazardous waste generated each month and the total amount of hazardous and acute hazardous waste the generator has on-site at one time. There are three categories of hazardous waste generators; they are often referred to as conditionally exempt small quantity generators (CESQG), small quantity generators (SQG) and large quantity generators (LQG).

Hazardous Waste Generator Categories

 

Acute Hazardous Waste

Hazardous Waste

 

Generation per

Month

Total Accumulation

On-site 

Generation per

Month

Total Accumulation

On-site 

CESQG

≤ 1 kg

≤ 1 kg

≤ 100 kg

≤ 1,000 kg

SQG

 

 

> 100 kg and < 1,000 kg

> 1,000 kg and < 6,000 kg

LQG

> 1 kg

> 1 kg

≥ 1,000 kg

≥ 6,000 kg

The following estimates will vary according to the density of the waste.

1 kg ≈ 1 qt

100 kg ≈ 27 gal (about ½ of a 55-gallon drum) or 220 lbs

1,000 kg ≈ 270 gal (about five 55-gallon drums) or 2,200 lbs

6,000 kg ≈ 1,620 gallons (about thirty 55-gallon drums) or 13,200 lbs

Note: Accumulation times vary according to generator status. Generation starts the moment a material is discarded.
