Storm Water Pollution Prevention Plan (SWPPP) Practice Test

What is a common potential pollutant found in vehicle maintenance areas?

1. Petroleum

2. Heavy metals

3. Fertilizers

4. Pesticides

The correct answer is: Petroleum

Petroleum is a common potential pollutant found in vehicle maintenance areas primarily due to the various products and fluids used during the maintenance of vehicles. Motor oil, gasoline, lubricants, and antifreeze are typical substances that can leak or be spilled during routine maintenance or repair work. These petroleum-based products can contaminate stormwater runoff if not managed properly, leading to significant environmental harm. In contrast, while heavy metals can also be present due to wear and tear on vehicle components, they are not as directly associated with the maintenance activities as petroleum products. Fertilizers and pesticides, although important pollutants in other contexts such as agriculture and landscaping, are less relevant in the context of vehicle maintenance areas. Thus, petroleum stands out as the most common and relevant pollutant in this specific setting.
