Subpart UU Flow Meters and Containers

This page provides step-by-step instructions on how to enter and update Subpart UU flow meter or container information.
Use this page to uniquely identify each receiving flow meter or container.

For each receiving flow meter or container at your facility, Subpart UU requires you to report the following information:

  • A unique name or identifier, plus an optional description for the flow meter or container (see also About Unique Unit Names).
  • Type of unit (flow meter or container)
  • An indication whether the flow meter or container measurement type is volumetric or mass-based
