Summary: In August 2005, the Environmental Protection Agency made the decision that the import of used railway sleepers should not be regarded as a waste provided that certain conditions were met. Due to what is deemed an excessive import of sleepers and potential illegal use issues, the EPA has classified used railway sleepers as a waste.
In 2006, the Environmental Protection Agency (EPA) reversed a decision made the year before and classified railway sleepers as waste. Previously, the EPA had decided that used railway sleepers would not be classified as waste subject to the fulfilment of certain criteria. This document outlines the rationale for the change of policy.
