According to NC Structural Pest Control Committee Rules, where must restricted use pesticides NOT be stored?

The guideline that restricted use pesticides must not be stored within 100 feet horizontally of any public water source is based on regulations aimed at protecting water supply and environmental health. This distance is designed to reduce the risk of any accidental contamination of drinking water sources. Storing pesticides too close to a water supply could lead to runoff or leaching, which may compromise the safety and quality of the public water system.

The specified distance also takes into account practical considerations for managing spills or leaks, ensuring that precautionary measures can be taken effectively. By maintaining this buffer zone, it helps safeguard aquatic ecosystems, as chemicals can have detrimental effects on water quality, fish, and other wildlife.

The other options might reference various safety or health regulations, but they do not align with the specific requirement concerning the storage of restricted use pesticides in relation to public water sources as dictated by the rules established by the NC Structural Pest Control Committee.
