ALCAN INGOT AND RECYCLING DIVISION OWNS AND OPERATES A PRI- MARY ALUMINUM REDUCTION PLANT IN SEBREE, KY. DURING THE MONTH OF JULY 1989, IT VIOLATED THE NEW SOURCE PERFORMANCE STANDARDS (NSPS) FOR PRIMARY ALUMINUM REDUCTION PLANTS, 40 CFR PART 60, SUBPART S - STANDARDS OF PRFORMANCE FOR PRIMARY ALUMINUM REDUCTION PLANTS, AND IN PARTICULAR, 40 CFR 60.192, STANDARDS FOR FLOURIDES. THESE PROVISIONS REQULATE THE AMOUNT OF TOTAL FLUORIDE EMISSIONS WHICH A PRIMARY ALUMINUM REDUCTION PLANT MAY DISCHARGE INTO THE AIR. ALCAN INGOT AND RECYCLING DIVISION VIOLATED THESE REGULATIONS WHEN IT EX- CEEDED THE TOTAL FLUORIDE EMISSION LIMIT BY 18%. ACCORDING TO DATA THAT HAS BEEN SUBMITTED TO OUR REGION SINCE THAT TIME, ALCAN INGOT AND RECYCLING DIVISION HAS BEEN IN COM- PLIANCE WITH APPLICABLE TOTAL FLUORIDE EMMISSION LIMITS SINCE RETESTING IN AUG 1989. REGION IV IS SEEKING PENALTIES FOR THE JULY 1989 VIOLATION OF NSPS FROM THIS COMPANY IN THE AMOUNT OF $6,000.00. ALCAN INGOT AND RECYCLING DIVISION HAS ADMITTED TO THE VIOLATION IN THIS MATTER, AND HAS ALREADY INDICATED ITS WILLINGNESS TO PAY THIS PENALTY AMOUNT. IN ADDITION TO SEEKING PENALTIES IN THIS MATTER, REGION IV IS RECOMMENDING INJUNCTIVE RELIEF WHICH WOULD RESTRAIN FUTURE VIOLATIONS AND REQUIRE THE COM- PANY TO TAKE ALL NECESSARY REMEDIAL MEASURES TO PREVENT FUTURE VIOLATIONS OF TOTAL FLUORIDE EMISSION STANDARDS AS EXPEDITIOUSLY AS POSSIBLE.
