Regulation 1138 - Emission Standards for Hazardous Air Pollutants for Source Categories

Section 17.0

"Emission Standards for Hazardous Air Pollutants for Area Source Prepared Feeds Manufacturing Facilities"

 

Background
Congress sought to reduce cancer and non-cancer health risks due to the exposure to hazardous air pollutants (HAPs) in the 1990 Amendments to the Clean Air Act. Under Section 112(k) - "Area Source Program", Congress mandated that the EPA identify the 30 or more HAPs that posed the greatest threat to public health in urban areas, and to identify the area sources (i.e., small source categories) that emit any of these pollutants, and to promulgate standards to address the emissions from those area sources.

In 1999, the EPA identified 33 HAPs that posed the greatest threat to public health and has, since that time, identified over 60 area source categories for which standards are to be promulgated. Click here for more information on the Federal "Area Source Program." 

On January 5, 2010, the EPA finalized another of these federal area source standards affecting Delaware facilities. The standard found at 40 CFR Part 63 Subpart DDDDDDD, is applicable to new and existing area source prepared feeds manufacturing facilities. 

NC Feed MillThe HAPs of concern in Section 17.0 are chromium and manganese compounds, which are added to animal feeds as micronutrients. Trivalent chromium compounds and manganese compounds are not classifiable as to their human carcinogenicity.  The major non-cancerous effects from chronic inhalation exposure are diseases associated with the respiratory tract (chromium compounds) and central nervous system (manganese compounds).  

The health effects of chromium and manganese compounds are provided in the link in the Reference Information, below.

The adoption process for Section 17.0 was suspended temporarily in the Fall of 2011 pending EPA's completion of changes that became effective on February 21, 2012.

EPA provides fact sheets describing the effects on human health of substances that are identified as hazardous air pollutants in the 1990 amendments of the Clean Air Act. These substances include certain volatile organic chemicals, heavy metals, pesticides, herbicides, and radionuclides that present tangible hazards, based on scientific studies of exposure to humans and other mammals.
