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.
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.
Absolutely! The ECOWISE program does not require a minimum quantity, nor does it obligate you to participate every month.
Basically, hazardous materials have any of these properties:
Businesses cannot bring more than 220 pounds of hazardous waste to the ECOWISE program. ECOWISE also accepts liquid latex paint -- but this is not considered a hazardous waste.
For chemicals and items not listed and for a price per pound, call 240-777-6587.
ECOWISE does not accept certain categories of hazardous materials because they contain certain reactive, ignitable, combustible, toxic, corrosive properies and/or health and safety dangers.
Fees are assessed on a per pound basis weighed at the point of collection.
Pay your ECOWISE fees with business checks made out to Clean Harbors Environmental Services, the County's current contractor for ECOWISE.
We do not accept cash payments.

Registration is free! Once you receive your packet of information, do a "Haz Waste audit" as described in your booklet. If your audit shows you generate less than 220 pounds per calendar month, you may join the ECOWISE program.
Simply notarize your signature on the affidavit with a raised notary seal and return it to us. Once we receive your application, we will notify you via email and/or a postcard regarding your acceptance into the program.
