All large power plants are required to do computerized projections of pollutant concentrations in the air at locations up to 30 miles away under all weather conditions. This is called computer modeling. If the modeled concentrations do not meet outdoor air quality standards, then the power plant must make changes to bring the predicted concentrations within the standards. Power plants are also required to measure emissions from their stacks so that emission rates do not exceed permitted levels. Some large power plants are also required to monitor pollutant concentrations at locations in their vicinity.
