What is the correct action when a spill or overflow occurs that exceeds federal reporting thresholds?

When a spill or overflow occurs that exceeds federal reporting thresholds, the appropriate action is to notify the implementing agency. This agency is typically responsible for overseeing environmental regulations related to hazardous substances and spills. Federal regulations, such as those set forth by the Environmental Protection Agency (EPA), require prompt notification to the relevant authority to ensure that the situation is assessed and managed promptly and correctly. This helps to minimize potential environmental damage and health risks associated with the spill.

Contacting the local fire department may be necessary if there is an immediate danger or threat to public safety, but it is not the primary action required for environmental compliance in the case of a spill exceeding established reporting thresholds. Similarly, conducting an internal investigation is important for understanding the cause and developing preventative measures, but it should follow the official report to the implementing agency and not replace the requirement to report. Waiting for an inspection is contrary to the obligation to proactively report incidents, as inspections typically occur after incidents are reported and do not substitute for immediate notification as required by law.
