NATIONAL SEMICONDUCTOR CORPORATION ( NSC ) OPERATES A FACILITY FOR SOLID-STATE SEMICONDUCTOR AND LEAD FRAME MANUFACTURING. AS PART OF ITS LEAD FRAME OPERATIONS, CARRIED OUT BY ITS SUBSIDIARY, DYNA-CRAFT, IT CONDUCTS METAL FINISHING OPERATIONS. NSC DISCHARGES INDUSTRIAL PROCESS WASTEWATER FROM ITS FACILITY TO THE CITY OF SAN JOSE'S SAN JOSE/SANTA CLARA JOINT WATER POLLUTION CONTROL PLANT. SINCE FEBRUARY 15, 1986, ALL EXISTING METAL FINISHERS THAT DISCHARGE TO SEWAGE TREATMENT PLANTS HAVE BEEN REQUIRED TO COMPLY WITH PRETREATMENT STANDARDS GOVERNING THE CHARACTER OF THEIR INDUSTRIAL WASTEWATER. FOLLOWING THE ISSUANCE OF AN ADMINISTRATIVE ORDER, NSC HAS INSTALLED NEW TREATMENT AND IS CURRENTLY IN COMPLIANCE WITH THE PRETREATMENT STANDARDS. REGION 09 IS SEEKING A CONSENT DECREE THAT WILL ASSESS PENALTIES FOR NSC'S PAST VIOLATIONS. NO INJUNCTIVE RELIEF SHOULD BE NECESSARY, ASSUMING THAT NSC REMAINS IN COMPLIANCE.
