Action: Michigan DEQ must begin monitoring Air Quality in South Central Michigan in the interest of protecting public health.
These levels dramatically exceed the Science Advisory Board (SAB) recommended proposed Ambient Air Levels (AALs). Each of the AALs are designed to be protective of specific health affects:
40 ppb – 1-hr standard, protective of human airway resistance
23 ppb – 24-hr standard, protective of human-eye pain
The 1800 ppm of Hydrogen Sulfide levels that Lenawee County (South Central Michigan) is experiencing is 60 times the air quality standards of Iowa, and 180 times Nebraska’s standards.
