Original warning text

Dolly Vardon Platform; Cook Inlet, Alaska.
Cook Inlet, Alaska.
1. At approximately 1530, on November 23, 1992, the waste liquids tank on the Marathon Dolly Vardon platform overflowed allowing oil to drain into Cook Inlet. A slick of approximately 40 gallons of waste crude and hydraulic fluid, about 200 yards wide by 3/4 of a mile long extended away from the platform. Marathon immediately dispatched a helicopter to track the slick until dark. After dark a Cook Inlet Spill Prevention and Response Inc. (CISPRI) spill response vessel tried unsuccessfully to locate the slick. A helicopter overflight the next morning found no trace of the oil. USCG district 17. Keyword: none.
2. COMMODITY: CRUDE AND HYDRAULIC OIL. MAXIMUM POTENTIAL RELEASE: 40 GALLONS.
3. POSITION 60.750N 151.667W. NOAA INCIDENTNEWS 6909: https://incidentnews.noaa.gov/incident/6909
