(Salem, OR) -- A Portland environmental services company is facing a 118-thousand dollar fine for workers who went into a confined space and passed out. The Oregon Occupational Safety and Health Division issued the fine against River City Environmental. Last July, two of their workers went into a stormwater sewer maintenance hole at a brewery to clean, retrofit and remove filters for stormwater runoff. Oxygen levels were too low and the workers lost consciousness and had to be rescued by Portland firefighters. The 118-thousand dollar penalty is proposed. River City Environmental has 30 days to appeal.
