Industrial gas facilities have distinct activities and associated environmental aspects that can impact the
environment. This publication provides good environmental practices at air separation and helium production
facilities, hydrogen and carbon monoxide facilities, and carbon dioxide facilities. It also provides good environ-
mental practices for truck maintenance and distribution, acetylene manufacturing, cylinder fill operations,
specialty gases operations, and customer installation (bulk tanks) activities.
The purpose of this publication is to identity typical compressed gas industry activities and associated environ-
mental aspects that can have a negative impact on the environment and to identify corresponding practices
that can minimize or eliminate those impacts. Environmental aspects can include wastes, discharges, and
releases generated at various industrial gas facilities (e.g., solid/hazardous waste, air emissions, wastewater
discharges, noise, etc.). For each activity, environmental aspects, potential environmental impacts, and good
environmental management practices (GEMP) have been identified that can be used to prevent pollution,
minimize the generation of wastes, discharges and releases, and properly manage any residuals.
