• Owner or operator means any person owning or operating an onshore facility or an offshore facility.

Owner or operator means any person owning or operating an onshore facility or an offshore facility, and in the case of any abandoned offshore facility, the person who owned or operated or maintained the facility immediately prior to such abandonment.

One commonly asked question about owners and operators is how a facility owner or operator should address a container located at the facility when the container is owned or operated by someone else. According to the Environmental Protection Agency (EPA), the owner or operator facility that includes a container being used by another person that is not under his or her operational control should coordinate with that person to determine who will prevent spills from that container

For example, transformers, or other energized electrical equipment, that are located on an easement and are under the operational control of the local electrical utility may be addressed separately by the utility. The facility owner or operator would typically not be required to include these containers in the Spill Prevention, Control, and Countermeasure (SPCC) Plan or on the facility diagram. The facility owner or operator should coordinate with the electric utility on how to address spill prevention procedures for this equipment. This determination by the plan holder must be based on site-specific factors.
