Wynnewood Refining Company

Wynnewood Refinery is a small crude oil refinery just outside Wynnewood in south-central Oklahoma. The only permitted activity as the refinery is a storage tank that holds hazardous wastes generated from the refining operations. The wastes are stored until sufficient volume is collected for transport to a permitted hazardous waste treatment, storage, or disposal facility. Permit conditions also require monitoring of contaminated groundwater.

Note: Some of the permit files may take some time to download because of their size.
