International Paper, Emissions Monitoring
International Paper's Androscoggin Mill, located in Jay, Maine, is proposing to develop, test, and implement a computer model that can estimate pollutant emissions on a continuous basis. Currently, International Paper is required to measure some of these pollutants only once every year. If successfully developed and implemented, this computer model would provide the surrounding community with information on emissions that is continuous, non-biased, credible, and reliable. IP is seeking regulatory flexibility in two areas. The first is to allow minor exceedances above existing permit limits to develop the computer model. The second area of flexibility requested is from the frequency of stack testing and the replacement of continuous emission monitoring with the computer model. These requirements are primarily embodied in state regulations that have been approved by EPA and are considered to be federally enforceable.
