A RCRA 3008(A) COMPLAINT, AS AMENDED, WAS FILED TO REQUIRE THE FACILITY TO BE IN COMPLIANCE WITH ALL REQUIREMENTS OF RCRA, INCLUDING THE CLOSURE OF AN ILLEGAL SURFACE IMPOUNDMENT. DURING THE COURSE OF NEGOTIATING A SETTLEMENT OF THE COMPLAINT, USEPA FIRST ENTERED INTO A RCRA 3008(H) CORRECTIVE ACTION ORDER ON CONSENT TO MEMORIALIZE TELEDYNE'S COMMITMENT TO CLEAN UP GROUNDWATER CONTAMINATION ON SITE, AS WELL AS TO FULLY CHARACTERIZE ALL CONTAMINATION ON SITE AND RECOMMEND REMEDIAL ALTERNATIVES VIA A FACILITY ASSESSMENT/CORRECTIVE MEASURES STUDY. UPON FURTHER NEGOTIATION OF THE CAFO TO RESOLVE THE AMENDED COMPLAINT, USEPA ASCERTAINED THAT THE FACILITY WAS IN VIOLATION OF THE CWA REQUIREMENTS IN THAT IT WAS DISCHARGING TREATED WASTEWATERS TO SURFACE WATERS OF THE STATE WITHOUT AN APPROVED NPDES PERMIT. USEPA THEREFORE CONTACTED OEPA, WHICH RESULTED IN THE FACILITY COMPLETING AN NPDES PERMIT APPLICATION AND BEING ISSUED AN NPDES PERMIT. USEPA AND OEPA WORKED WITH EACH OTHER TO ENSURE THAT THE NPDES PERMIT AND 2 RCRA CONSENT AGREEMENTS WERE COMPATIBLE WITH EACH OTHER IN THEIR GOALS AND PROVIDED AN ENVIRONMENTALLY SOUND APPROACH TO RESOLVING SOLID WASTE DISPOSAL, GROUNDWATER AND SURFACE WATER PROBLEMS ASSOCIATED WITH THE SITE.
