Facility
Facility means any mobile or fixed building, property, parcel, lease, structure, installation, equipment, pipe, or in-plant pipeline (other than a vessel or a public vessel), used in CWA hazardous substance handling, production, manufacturing, storage, processing, refining, transfer, distribution, treatment, or in which any CWA hazardous substance is used. The boundaries of a facility depend on several site-specific factors, including but not limited to, the ownership or operation of buildings, structures, and equipment on the same site and types of activity at the site. Therefore, contiguous or non-contiguous buildings, properties, parcels, leases, structures, installations, pipes, or pipelines under the ownership or operation of the same person may, for legitimate operational and response planning reasons, be considered separate facilities.
