Additions to List of Categorical Non-Waste Fuels: Other Treated Railroad Ties

The Environmental Protection Agency (EPA) is issuing amendments to the Non-Hazardous Secondary Materials regulations, which generally established standards and procedures for identifying whether non-hazardous secondary materials are solid wastes when used as fuels or ingredients in combustion units. In February 2013, the EPA listed particular non-hazardous secondary materials as ``categorical non-waste fuels'' provided certain conditions are met. This final rule adds the following other treated railroad ties (OTRT) to the categorical non- waste fuel list: Processed creosote-borate, copper naphthenate and copper naphthenate-borate treated railroad ties, under certain conditions depending on the chemical treatment.
