AMERICAN METAL FABRICATORS, INC., (AMF) OPERATES A METAL SHAPING AND FINISHING FACILITY IN HUDSON, NEW HAMPSHIRE. SINCE 1980 AMF HAS BEEN DISCHARGING POLLUTANTS FROM THIS FACILITY INTO AN UNNAMED TRIBUTARY OF THE MERRIMACK RIVER. PRIOR TO 1980 AMF HAD BEEN ANGAGED IN THE SAME OPERATIONS BUT IT WAS LOCATED IN ANOTHER BUILDING IN THE IMMEDIATE AREA. ITS PRACTIVE OF DISCHARGING POLLUTANTS APPEARS TO DATE BACK AT LEAST TO 1978. AMF'S DISCHARGES CONTAIN TOXIC POLLUTANTS. AT THE TIME WHEN STATE OFFICIALS DISCOVERED THAT THE CO WAS DISCHARGING WITHOUT A PERMIT, IN 1982, THE CO HAD NEVER APPLIED FOR A PERMIT. ON NOVEMBER 23, 1982, EPA SENT THE CO AN APPLICATION FOR A PERMIT, BUT THE CO HAS NOT COMPLETED THE APPLICATION. IT APPEARS THAT THE CO WILL NEED TO BUILD TREATMENT FACILITIES TO MEET EXPECTED EPA PERMIT LIMITS. THE CO PRESENTLY DISCHARGES ITS WASTES UNTREATED. * FACILITY ADDRESS: 22 FLAGSTONE DR HUDSON, NH 03054 OWNERSHIP: P SIC CODE: 3499 EPID# NHD085586014
