This Environmental Management System Implementation Guide for the Foundry Industry (EMS Guide) is a combination of examples and tools from EPA-sponsored EMS source documents and actual industry examples developed during the EPA Sector Strategies Foundries EMS pilot. The EMS Guide is meant to assist foundries in weaving environmental decision-making into the fabric of the way they do business. The purpose is not only to achieve better compliance assurance, but also to improve environmental performance in areas such as resource conservation, energy efficiency, water-use efficiency, land use, and mitigation of impacts associated with noise, odor, and dust. As a result of comprehensive planning, rigorous implementation, regular checking, and effective corrective action, EMSs are helping foundries to consistently meet their environmental goals and commitments. Foundries that have an effective EMS are becoming more efficient and more competitive.
