The term ''source reduction'' [or pollution prevention] means any practice which (i)
reduces the amount of any hazardous substance, pollutant, or contaminant entering any
waste stream or otherwise released into the environment (including fugitive emissions)
prior to recycling, treatment, or disposal; and (ii) reduces the hazards to public health
and the environment associated with the release of such substances, pollutants, or contaminants.
The term includes equipment or technology modifications, process or procedure
modifications, reformulation or redesign of products, substitution of raw materials,
and improvements in housekeeping, maintenance, training, or inventory control.
The term ''source reduction'' does not include any practice which alters the physical,
chemical, or biological characteristics or the volume of a hazardous substance, pollutant,
or contaminant through a process or activity which itself is not integral to and necessary
for the production of a product or the providing of a service.”vii
