## Abstract

This final rule is issued to revise sections of the Alcohol and Controlled Substances (D&A) Testing regulation to reflect recent amendments to the law. The final rule also includes technical corrections to the D&A testing regulation to more clearly explain existing compliance requirements, update regulatory terms, and remove repealed statutory provisions. Because this rule merely implements a statutory provision without agency interpretation FTA finds that public comment is unnecessary under the circumstances.
