"New Source MACT and Residual Risk at an Iron Foundry"
ABSTRACT
Expansion of three Wisconsin grey and ductile iron foundries required an air quality construction permit under the Prevention of Significant Deterioration air quality regulations. In addition, state and federal regulations included a determination of Maximum Available Control Technology (MACT) for hazardous air pollutants (HAP) and evaluation of the air quality impacts of residual emissions. Proposed changes to the state air toxics regulations will allow facilities to either control HAP emissions or demonstrate the residual risk does not pose a hazard to human health or the environment. The HAP emissions, new source MACT determinations, estimates of residual risk for these projects are presented.
