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.
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."
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.
Registration is free! Once you receive your packet of information, do a "Haz Waste audit" as described in the Ecowise Guide. If your audit shows you generate less than 220 pounds per calendar month, you may join the ECOWISE program.
