The ECOWISE program provides Montgomery County businesses, or Small Quantity Generators ( SQG), who generate less than 220 pounds (or 100 kg) of hazardous waste an inexpensive and convenient way of disposing of their hazardous material.

A SQG must also generate less than 2.2 pounds (1 kg) of acute hazardous waste per month.

"a solid waste that has been found to be fatal to humans in low doses or…is otherwise capable of causing or significantly contributing to an increase in serious irreversible, or incapacitating reversible, illness."
