The Secretary shall establish a hazardous air contaminant monitoring program. The goals of the program shall be to:
(1) measure the presence of hazardous air contaminants in ambient air;
(2) identify sources of hazardous air contaminants;
(3) assess human health and ecological risk to focus studies on those air contaminants that pose the greatest risk;
(4) gather sufficient data to allow the Secretary to establish appropriately protective standards; and
(5) ensure adequate data are collected to support the State’s operating permit program.
