Government and Regulatory


AFS is committed to providing the metalcasting industry with the latest information and rules affecting air emissions in metalcasting facilities. For more information on EPA regulations for air, visit the U.S. EPA's Office of Air & Radiation Website.

Casting Emission Reduction Program

Environmental Protection Agency

Iron & Steel Area Source Standards: On January 2, 2008, EPA published the final iron and steel foundry area source rule in the Federal Register.  EPA issued the standard based on generally available control technology (GACT) for the control of the following urban hazardous air pollutants (HAPs):  chromium, lead, manganese and nickel. The final rule sets emission limits for large area source foundries and requires both large and small area source foundries to comply with pollution prevention management practices and notification and record keeping requirements.

Nonferrous Area Source Rule: The U.S. Environmental Protection Agency (EPA) has issued a final regulation to reduce hazardous air pollutants (HAPs) from aluminum, copper and other nonferrous metalcasting area sources.  Area sources are those facilities that emit small amounts of HAPs.

Iron & Steel MACT: Read updates on the Iron and Steel MACT rule and how they affect the casting industry.

Urban Air Toxics Strategy: The air toxics strategy from EPA is a framework for addressing air toxics emissions in urban areas.

Form R: Reporting of Binder Chemicals Used in Foundries - 4th Edition: This document, written and compiled by AFS is provided to help foundries more accurately report on the uses and releases of binder chemical systems.

Organic HAP Emission Factors 2007: This document prepared by the AFS Air Quality Committee (10-E) provides iron foundries with guidance on the selection of organic HAP emissions factors for pouring, cooling and shakeout operations and to a limited extent for nobake molding operations.
