An EPA administrative law judge ordered a plumbing company to pay $630,000 for RCRA violations at its on-site landfill. The judge also ordered the company to refrain from all land disposal of wastes that fail to meet applicable treatment standards, ensure that the hazardous waste treatment process for any waste subject to such standards is effective prior to land disposal, and cease using any hazardous waste container that cannot demonstrate compliance with applicable hazardous waste container management requirements.
