Which action is inappropriate when the owner/operator becomes aware of a spill or overfill?

Draining a spill to the storm sewer or nearby ditch is considered an inappropriate action because it may lead to environmental contamination and violate regulatory requirements. When a spill or overfill occurs, proper containment is essential to prevent the hazardous substances from entering waterways, soil, and potentially affecting public health.

Legally and ethically, the correct steps involve notifying regulatory authorities, such as the Department of Environmental Quality (DEQ), to ensure that the spill is managed according to established protocols. Additionally, containing the spill on-site minimizes the impact on surrounding areas. Evacuating the area if necessary is also an important step to ensure the safety of individuals in proximity to the spill.

Overall, proper procedures are critical to mitigating the effects of a spill and ensuring compliance with environmental regulations.
