Omnibus Hazardous Waste Act of 1991



______________________________________________________________________________ Definitions
Hazardous waste -- Garbage, refuse, sludge from a waste treatment plant, water supply treatment plant or air pollution control facility, or other discarded materials, including solid, liquid, semisolid or contained gaseous material, resulting from industrial, commercial, mining and agricultural operations or from community activities which because of its quantity, concentration or physical, chemical or infectious characteristics may cause or significantly contribute to an increase in mortality or an increase in serious irreversible or incapacitating reversible illness or pose a substantial present or potential hazard to human health or the environment if improperly treated, stored, transported, disposed of or otherwise managed.
Pollution -- The disposal of a toxic substance or hazardous waste into the air, land, surface water or groundwater.
Pollution Prevention -- Operational procedures, processes, and improvements in housekeeping or management techniques that reduce potential or actual releases of pollutants to the overall environment including all air, water and land resources affected by those pollutants. This includes:
a. toxics use reduction, source reduction, recycling of wastes or secondary materials, waste minimization, reuse, reclamation, conservation and substitution.
b. proportionate changes in the total volume, quantity or toxicity of a particular pollutant as a result of production changes or other business changes (such as improvements in operating practices, spill and leak prevention measures, inventory control). This does not include transfer or relocation of an operation or process to another facility with no subsequent proportionate reduction in toxics use or release of pollutants.
c. On-site or off-site treatment if that treatment can be shown to confer a higher degree of protection to overall public health and safety than other technically and economically practicable waste reduction alternatives.
