Commercial and Industrial Solid Waste Incinerator Units (CISWI)

This site provides more information about a proposed rule published in the Federal Register (FR) on June 4, 2010, which will reduce emissions from commercial and industrial solid waste incinerators. An incinerator unit covered under this rule is any device used to burn solid waste at a commercial or industrial facility. The rule does not include Municipal Solid Waste Incinerators, which are covered under separate rules. Click here for more information on commercial and industrial solid waste incinerators. Public comment period ends August 23, 2010.


Why is this proposed rule important to me?

Incineration of solid waste produces toxic air pollutants. Toxic air pollutants, also known as hazardous air pollutants, are those pollutants that are known or suspected to cause cancer or other serious health effects. This proposed rule is designed to reduce the emissions of toxic air pollutants from commercial and industrial solid waste incinerators, which may be affecting your health or the health of your family or neighbors.

Closely related rules.

Commercial/Industrial Solid Waste Incinerator Units (CISWI) and Industrial, Commercial, and Institutional Boilers and Process Heaters (ICIB) are closely related because similar units may be considered boilers or incineration units based on whether or not they burn solid waste materials. See the Industrial, Commercial, and Institutional Boilers and Process Heaters (ICIB) webpage for additional information.

EPA has proposed a definition of solid waste for non-hazardous secondary material. One potential implication of the proposed definition of solid waste is that some combustion units currently considered boilers would be subject to the proposed CISWI standards in the energy recovery unit subcategory if they continue to combust solid waste.
