It is the policy of the State to reduce the amount of the toxic substances used in the State, to reduce worker and environmental exposure to the release of toxic substances, to reduce the hazardous waste generated within the State and to minimize the transfer of toxic pollutants from one environmental medium to another. The State encourages an integrated approach to toxics use reduction, toxics release reduction and hazardous waste reduction based on the hierarchies of pollution prevention management strategies included in this section. It is further the policy of the State that the process of reducing the use and release of toxic substances and reducing the generation of hazardous waste through planning and analysis of manufacturing and commercial processes is ongoing and that the principles of continuous improvement in pollution prevention and open, public accountability must be applied to environmental quality management efforts in both public and private facilities.
