It is very clear that chemical engineers must be versed in the latest federal and state regulations involving environment protection, worker safety, and health. This need is especially great for engineers in design-related functions, such as capital cost estimating, process and equipment design, and plant layout. It is particularly important to determine what is legally required by EPA, OSHA, and corresponding regulatory groups at the state and local levels. As a minimum, every design engineer should understand hoe the federal regulatory system issues and updates its standards.
