EPA Proposal Problematic

摘要

Like death and taxes, there are certain inescapable realities of operating a power plant. For example, coal-fired plants often exceed emission limits during startup, shutdown or malfunction (SSM). Similar to an engine in a car, emission control equipment in a power plant must warm up before the plant can effectively control emissions. The chemical reactions required for controlling emissions cannot occur in the cold. It's a technical reality associated with the operation of combustion boilers and has long been recognized by EPA rules that exempt utilities from exceeding emission limits during SSM events.
