Since the essential purpose of this guide book is to provide working managers with a comprehensive introduction to practical operational aspects of hazardous waste management and with an extremely important foundation in relevant laws, rules, and regulations, it is not our place nor our intention to enter into the debate of the relevant responsibility or lack thereof of past or present actions of the private or public sectors. Rather our purpose is to concentrate on those aspects of hazardous waste management which we feel either have not been previously addressed, insufficiently examined, or most importantly not considered in an integrated fashion.
