Storage Shed Inventory and a Leaking Container
A grower's pesticide storage shed sits 40 feet from a wellhead and 25 feet from a drainage ditch that leads to a stream. Inside: partially filled jugs of an emulsifiable concentrate, a bag of granular herbicide with a torn corner, and an unlabeled plastic bottle of a liquid concentrate. A shelf holding the EC jugs has a puddle of amber liquid beneath it. The shed has no secondary containment, is not locked, and the temperature reaches 100°F in summer. The grower wants to "just hose it out" into the ditch.
1. List the storage violations and the environmental risks they create.
Read the worked answer
Violations and risks:
- Proximity to wellhead (40 ft) and ditch (25 ft): many states require minimum setback distances and impermeable floors with containment; a spill could reach groundwater or surface water directly.
- No secondary containment: a leaking EC puddle can migrate; ECs are formulated with petroleum solvents and are toxic to aquatic life.
- Unlabeled bottle: illegal and dangerous - identity and label directions are lost; cannot be legally used or disposed of as labeled.
- Torn granular bag: granules can spill, be tracked out, or reach water; granular herbicides are highly water-soluble and can contaminate the ditch/stream.
- Unlocked shed: unauthorized access risk (children, animals), a legal and liability issue.
- 100°F heat: accelerates degradation, increases vapor pressure and fire risk for solvent-based ECs, and can rupture containers.
Environmental risk: contamination of groundwater (well) and surface water (ditch/stream), plus soil and air.
2. The grower says "I'll just hose it into the ditch." Explain why that is illegal and give the correct cleanup and storage plan.
Read the worked answer
Hosing into the ditch is illegal - it is a point-source discharge of a pesticide to waters of the state, violating FIFRA label disposal instructions and the Clean Water Act/state water law. It can kill aquatic life, contaminate downstream water, and trigger enforcement and cleanup liability.
Correct plan:
- Contain the spill: absorb the puddle with inert absorbent (kitty litter, vermiculite, sawdust), sweep up, and place in a labeled, sealed container for disposal per label and state hazardous-waste rules.
- Do not rinse to the ditch; clean the floor and contain rinseate.
- Identify the unlabeled bottle if possible; if not, treat as unknown waste and dispose through a licensed hazardous-waste handler.
- Reseal or repackage the torn granular bag into a labeled container.
- Relocate storage away from the well and ditch, add impermeable floor and secondary containment, lock the shed, and keep it ventilated/cool.
- Keep an inventory and SDS/labels on file; post warning signs.
Document the spill and disposal for regulatory records.
