Waste Disposal
It is the responsibility of
chemical waste generators to determine the toxicity and
physical properties and of a discarded chemical and to
properly identify its classification and certification as a
hazardous waste and to determine the disposal method.
United States Environmental Protection Agency guidelines
for the classification determination are listed in 40 CFR
Parts 261.3. Additionally, waste generators must consult
and follow all regional, national, state and local hazardous
waste laws to ensure complete and accurate classification
and disposal methods. Follow recommendations for the
disposal of pesticides and pesticide containers. Containers
must be disposed of properly by following package label
directions or by contacting your local or federal environmental
control agency, or by contacting your regional
EPA office.
