EIA-860 Ash Impoundment Plants

The annual EIA-860 plant file reports ash-impoundment presence, lining, and year-end status at a named and located plant and identifies the legal company responsible for day-to-day generator operations by Utility ID and Utility Name. It directly supports an organisation-associated-plant screen when that exact relationship is preserved; it does not prove that the utility owns, permits, or operates the impoundment.

The open annual EIA-860 full file provides plant-grain records for plants reporting an ash impoundment, with plant address and coordinates, impoundment-presence indicator, lined indicator, and operating status as of December 31 of the reporting year. It supports parcel-centered proximity screening after a documented spatial match, while remaining a plant-grain self-report rather than impoundment geometry or the EPA-regulated CCR universe.

The annual downloadable EIA-860 plant file identifies each plant by code and name, supplies its street address and coordinates, and identifies by Utility ID and legal Utility Name the company responsible for day-to-day generator operations. For the ash-impoundment subset this supports a dated externally reported operating-location observation for that utility, subject to the limits that it is not a complete organisation footprint and does not prove plant ownership, brand affiliation, or operation of the impoundment itself.
