This document contains the methods and the results of baseline risk assessments (i.e., after the implementation of the MACT standard) and the results of the post-control scenario risk assessment performed for the ferroalloys source category. The methods discussion includes descriptions of the methods used to develop refined estimates of chronic inhalation exposures and human health risks for cancer and noncancer endpoints, as well as descriptions of the methods used to screen for acute health risks, chronic non-inhalation health risks, and adverse environmental effects.
