Significant Harm Level:
•EPA also is proposing to set a Significant Harm Level (SHL) for PM2.5 equal to the proposed AQI value of 500, which is 500 μg/m3. Areas rarely reach PM concentrations of this level.
•An SHL is an important factor in designing air pollution Emergency Episode Plans, which are required for certain areas of the country.
