'NJNG failed to identify waste as PCB waste on the disposal manifest, and so caused the improper disposal of the material in a non-TSCA landfill. Respondent subsequently paid to have the material removed from the landfill and properly disposed. Respondent was issued a Notice of Opportunity Related to Enforcement Action under TSCA (a Show Cause letter) on April 18, 2002. The enforcement case was simultaneously opened and closed with the CA/FO.'
