FROM 1987 TO 1991, TRIANGLE PETROLEUUM OPERATED A STORAGE FACILITY AT THE SITE. WASTE OIL AND CHEMICALS WERE TRUCKED TO THE SITE BY TRIANGLE PETROLEUM, BOTH IN 55-GALLON DRUMS AND IN BULK FORM. SOME OF THE WASTE OIL AND CHEMICALS WERE PUMPED INTO TANKS AT THE SITE FOR STORAGE, AND THE REST WAS STORED IN 55-GALLON DRUMS. SOME OF THE WASTE OIL WAS TRANSPORTED OFF-SITE FOR USE IN DUST SUPPRESSION IN COAL MINES. AT LEAST FOUR ABOVE GROUND STORAGE TANKS AND 250 DRUMS CONTAINING WASTE OIL AND CHEMICALS WERE LEFT ON-SITE WHEN TRIANGLE PETROLEUM CEASED OPERATIONS AT THE STORAGE FACILITY. SMALL SPILLS OF WASTE OIL OCCURRED DURING THE RESPONDENTS OPERATIONS. CURRENTLY, SOME OF THE DRUMS ARE OPEN AND PRODUCT OVERFLOWS FROM THOSE DRUMS DURING RAIN EVENTS. SOIL STAINING IS APPARENT AROUND MANY OF THE DRUMS AND THE STORAGE TANKS, AND THERE IS LITTLE VEGETATION GROW- ING AT THE SITE.
