Inhalation risk assessment for existing Maryland power plants. Final report
Technical Report
·
OSTI ID:104273
An inhalation risk assessment was performed for all Maryland utility combustion sources, i.e., turbines, diesel engines, and coal and oil-fired boilers. This assessment involved 15 power plants sites comprising approximately 70 combustion units. The goal was to determine whether exposure to hazardous air pollutant (HAP) emissions (via inhalation) from any individual source or from all sources is likely to pose a significant health risk to the most exposed individuals (MEI). This assessment was based on conservative emissions and toxicological information, and is designed to be easily updated as new data become available. Existing unit-specific emissions data, accounting for furnace type, firing technique, and control technology, were used. Detailed dispersion modeling, accounting for site-specific effects such as structure downwash and terrain, was used to estimate potential inhalation exposure. Available toxicological data were used to estimate the risk posed by each utility combustion source in Maryland, and to identify any hazardous air pollutant emissions of concern.
