On March 24, 2014, U.S. EPA issued a proposed amendment to the Non-Hazardous Secondary Materials (NHSM) Rule that includes additional materials that will be categorically treated as fuels (and not wastes) when burned for energy recovery. The following materials are included in the proposed rule:
- Construction and demolition (C&D) wood processed from C&D debris according to best management practices,
- Paper recycling residuals, including old corrugated cardboard (OCC) rejects, generated from the recycling of recovered paper and paperboard products and burned on-site by paper recycling mills the boilers of which are designed to burn solid fuel, and
- Creosote treated railroad ties that are processed and combusted in units designed to burn both biomass and fuel oil.
