Operations within the scope of this standard include natural gas processing and associated gas compression facilities. The publication coverage begins with initial plant planning, permitting, and construction and ends with plant closure and site restoration procedures. General guidelines are provided to be used at gas plant locations to develop sitespecific environmental programs. This standard does not address safety or operational issues except where environmental, safety, and operational issues are intertwined. Process design and equipment selection are not addressed in detail. This publication does not specifically address requirements of process safety management (refer to 29 CFR Part 1910.119) that must be considered in gas plant design and operations.
