SUMMIT COUNTY HEALTH OFFICIALS ARE ASKING RESIDENTS -- WHO LIVE ALONG ECHO CREEK -- TO KEEP AN EYE OUT FOR CONTAMINATION, AFTER A CRASH SENT ABOUT 70 GALLONS OF DEISEL FUEL INTO THE WATER.

NORTH SUMMIT FIRE OFFICIALS SAY THE SPILL OCCURRED THURSDAY NIGHT, WHEN A SEMITRAILER AND AN S-U-V CRASHED, ON I-80.

THE IMPACT CAUSED ONE OF THE SEMI'S TRAILERS TO ROLL ON ITS SIDE... AND ALSO RUPTURED THE TRUCK'S GAS TANK.

OFFICIALS SAY HAZARDOUS MATERIALS CREWS PUT UP BOOMS IN THE STREAM, TO CATCH THE DEISEL FUEL, BEFORE IT FLOWED INTO THE WEBER RIVER.

THE TRUCK DRIVER -- AND THE TWO PEOPLE IN THE S-U-V -- WERE NOT SERIOUSLY INJURED.
