Chapter IV of the Wyoming Water Quality Rules and Regulations (WWQRR) regulates the containment, cleanup and disposal of oil or hazardous substances released to waters of the state, or which threaten to enter waters of the state.
A "release" is defined as, but is not limited to, any sudden spilling, leaking, pumping, pouring, emptying, emitting, discharging, dumping, addition of, escaping, leaching or unauthorized disposal of any oil or hazardous substance which enters or threatens to enter waters of the state. Intentional discharges of oil or hazardous substances are regulated by WYPDES permits. Click here for further information about WYPDES permits.
"Oil" means insoluble or partially soluble oil of any kind including, but not limited to, crude or fuel oil, lubricating oil, oily sludge, asphalt, crude oil condensate, gasoline, aviation fuel, kerosene, diesel motor fuels, road oil, waste oil, oil mixed with federally defined, non-hazardous wastes and derivatives of mineral, animal or vegetable oils.
"Hazardous substance" means any substance or water, which after release, constitutes a threat to public health or welfare, or other aquatic life or wildlife because of its quantity, concentration, chemical, corrosive, flammable, reactive, toxic, infectious, or radioactive characteristics. The term also includes all substances so designated by the United States Environmental Protection Agency (EPA). The term does not include oil.
"Waters of the state" means all surface and groundwater, including waters associated with wetlands, within Wyoming.
What spills are reportable?
Pursuant to Chapter 4 of the WWQRR, the following spills/releases are reportable to the DEQ:
- Releases of "oil" and "hazardous substances" which enter waters of the state.
- Releases that are determined to be a threat to enter waters of the state and are: a) considered a "hazardous substance", or b) any amount greater than either 10 barrels of any combination of crude oil/petroleum condensate/produced water OR 25 gallons of refined crude oil products.
- Suspected releases from above or underground storage tanks are regulated by Chapter 17, WWQRR. For more information on underground storage tanks, click here.
