Fifteen Gallons in a Ditch Above the Irrigation Pond
A pickup carrying a 150-gallon nurse tank and a pallet of 2.5-gallon jugs of a liquid concentrate slides into a barrow ditch on a county road. The tank lid cracked and roughly 15 gallons of concentrate ran into the ditch and is soaking into the shoulder. The ditch drains about 150 feet to a tailwater pond used for irrigation, and a domestic well sits roughly 300 feet downslope in the same direction. It is 92°F with a 5 mph wind, and traffic is passing in both directions. The driver's spill kit holds four absorbent pads, one bag of clay absorbent, a shovel, duct tape, one pair of nitrile gloves, and a 5-gallon bucket. The label's Section 6 says to contain the spill and not to use water.
1. Order the first thirty minutes. Explain what you do first and what you deliberately do not do, and why each choice matters downstream.

Order of operations:
- People before product. Park upwind and uphill, set out triangles or flares for traffic, move the driver upwind, and put on the gloves. No PPE, no approach - the most common way a small spill becomes two injuries is an ungloved helper.
- Stop the source. Upright the jugs, tape or plug the cracked lid, and secure the tank so nothing more drains. Containment before cleanup.
- Keep it out of the water. With a 150-foot run to the pond, use the shovel to throw a soil dike across the ditch below the spill before it reaches the pond, then work uphill: pads on the free liquid, clay absorbent on the shoulder, a soil berm around the soaked patch. Do not chase the plume toward the pond by walking downslope in it.
- Do not use water. Dilution spreads the release, deepens the contamination zone, and pushes it toward the pond - exactly what the label's Section 6 forbids.
- Do not bury it, do not wash it into a storm drain, and do not leave absorbent in the ditch unbagged. Bag used absorbent and contaminated soil in the bucket or heavy bags.
- Call. 911/highway patrol for the roadway, the employer, CHEMTREC or the registrant, the state agriculture department's spill line, the landowner, and the well owner. Keep the label and SDS with you.
2. How do you decide whether this is a reportable release and who must be notified? What records does this create?
Read the worked answer
Decision logic, not guessing. Reporting turns on the product's active ingredient, its concentration, and whether the release exceeds a regulatory threshold or poses a threat to water. You do not decide from the smell or the stain: read the label and SDS (Section 6 for spill handling, Section 15 for regulatory notes), find the active ingredient, and check whether it is a CERCLA hazardous substance with a reportable quantity. A concentrated release of roughly 15 gallons is large enough that it very likely trips the federal National Response Center threshold for at least some actives, and irrigation water and a domestic well within a few hundred feet make the threat credible regardless. When in doubt, report - over-reporting is not a violation.
Likely notifications: National Response Center (federal release line), Colorado's spill/emergency line and the state agriculture department, the county sheriff or highway patrol for the roadway, CHEMTREC for technical help, the landowner, the pond's water users, and the well owner, who may need to test.
Records to create today: time discovered, what was released and how much, product name and EPA registration number, weather, photographs, containment steps, absorbent and soil quantities removed, each agency contact and confirmation number, disposal manifest for the contaminated soil, and a written incident report with corrective action. Keep copies with the application records.
3. The cleanup is finished. What goes in the disposal plan, and what would you change about the truck and kit so the next spill is smaller?

Disposal. Contaminated soil, used absorbent, and the damaged jugs are pesticide-contaminated waste and cannot go in a burn barrel, a ditch, a landfill dumpster, or the field. Check the label's disposal section and Colorado solid and hazardous waste rules, triple-rinse or pressure-rinse the empty jugs, add the rinseate to the spray tank as the label allows, then puncture and dispose of the containers through an acceptable container-recycling program. Segregate contaminated soil into a labeled drum and hold it pending characterization; use a licensed hauler and keep the manifest. Rinse the box, bed, and tools over a container, not on the ground, and decontaminate gloves and clothing separately from family laundry.
Hardware fixes, all cheap compared with what just happened:
- A spill kit rated for 30+ gallons with absorbent socks/boom (not just pads), a drum or heavy bags, and a large enough quantity of absorbent for a tank breach.
- Secondary containment for the pallet of jugs, and tie-downs or straps on the nurse tank.
- A lid and valve guard or a lockable ball valve, which is what actually failed here.
- Gloves that fit, goggles, a face shield, and a reflective vest for road work at night.
- Field-fitted emergency cards: who to call, what the label says, and where the nearest water is.
- Driver training and a pre-trip checklist covering tank lids and load security, so the spill never starts.
