What is ECOWISE?
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. Acute hazardous waste is defined under Code of Maryland Regulations, Title 26, Subtitle 13, Section 02.09 (26.13.02.09) Article A(2) as: "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." Refer to Code of Maryland Regulations 26.13.02.09 for a complete description of acute hazardous waste.
What is a Small Quantity Generator?
In the State of Maryland, a "Small Quantity Generator" or SQG is a non-residential (business or non-profit organization) entity that generates less than 220 pounds (100 kg) of hazardous waste per calendar month. A "Conditionally Exempt Small Quantity Generator" (CESQG) is the Federal equivalent term. BOTH terms mean you produce less than 220 pounds or 100 kg per calendar month. A SQG must also generate less than 2.2 pounds (1 kg) of acute hazardous waste per month.
The Federal government defines a "Small Quantity Generator" (SQG) as producing between 220 pounds (100 kg) and 2,200 pounds (1000 kg) per year. The ECOWISE program is not open to businesses that are federally defined as SQGs, since they produce more than the program allows.
I don't produce as much as a State of Maryland defined SQG in a single month. Do I still qualify to participate?
Absolutely! The ECOWISE program does not require a minimum quantity, nor does it obligate you to participate every month.

- Businesses save up to 75% of costs to dispose of hazardous material compared to having a conventional pickup and disposal hazardous waste company come to your business or organization.
