Frequent Questions

Is there an authoritative US EPA definition for a term?

There are no U.S. EPA sanctioned and approved vocabularies or term definitions.  There are vocabularies and terms with definitions that have been approved by various EPA Offices, such as the Office of Environmental Information's Web Taxonomy.  There is also legal terminology for various statutes and regulations that is authoritative for that legal context.
