Thirty Gallons of Acid Into a Creek and a Trooper Who Says Not to Call
You are 14 miles east of Lexington on I-81 when a passenger car sideswipes your van trailer carrying 2,400 lb of UN1789, Hydrochloric acid, 8, PG II. Two 55-gallon drums rupture, and roughly 30 gallons of acid run off the shoulder into a drainage ditch that feeds a creek.
A state trooper is on scene. One motorist complains of burning eyes but refuses transport. The right lane is blocked for about 40 minutes while the fire department washes the shoulder; the interstate itself stays open. No one is killed or hospitalized. Damage to the trailer and drums has not been estimated.
The trooper asks for "the paperwork on what's in there" and then tells you, "Don't call anybody. I'll handle it."
1. Apply the Part 171 incident criteria to these facts. Is this a reportable incident, and what is still unknown?

Work through the criteria one at a time.
| Criterion | Facts here |
|---|---|
| Fatality | No |
| Injury requiring hospitalization | No - burning eyes, refused transport. "Refused transport" is not hospitalization. |
| General public evacuated 1 hour or more | No |
| Major transportation artery closed 1 hour or more | No - one lane for 40 minutes; interstate stayed open |
| Property damage over $50,000 | Unknown - no estimate yet |
| Releases of certain radioactive, infectious, or marine pollutant quantities | 30 gal is below the 119-gallon marine pollutant liquid threshold, and HCl is not a marine pollutant |
On the Part 171 criteria alone, this may not qualify - but you cannot close that out yet, because the property-damage figure is unknowable at the scene. Trailers, drums, guardrail, pavement repair, and cleanup costs can each push a scene like this over the line.
The bigger point: the acid went into a ditch that feeds a creek. A release to a waterway triggers notification obligations under the Clean Water Act and to state environmental authorities regardless of whether the Part 171 thresholds are met. The Part 171 analysis is not the whole analysis.
2. The trooper tells you not to call anyone. What are your obligations, and to whom?

An officer at the scene cannot waive federal reporting duties.
1. Emergency response - immediately. The fire department is already there; keep that going. Do not let anyone talk you out of an emergency response.
2. Your carrier - immediately. The legal reporting duty under 49 CFR 171.15 sits with the carrier, and the carrier must telephone the National Response Center (1-800-424-8802) as soon as practical and no later than 12 hours after the incident. Your job is to make sure the carrier knows within minutes so that window is not burned. Call dispatch.
3. State environmental authorities - the acid is moving toward a creek. The carrier and the on-scene responders should be notifying the state DEQ; make sure that has actually happened.
4. The trooper gets the shipping paper - hand over the papers and the ERG guide number. That is exactly what he asked for and what responders need.
5. Isolate. Hydrochloric acid is a corrosive; keep people uphill and upwind, out of the low ground where the vapor and runoff are going. Do not attempt cleanup beyond your training or your equipment - 30 gallons in a ditch is a responder job.
Do not say "the trooper told me not to." Log the time, the reporting decision, and who you notified.
3. What follows in the days after the scene is cleared?
Read the worked answer
Two tracks: the written report and the evidence.
Written report: the carrier files the detailed hazardous materials incident report (DOT Form 5800.1) within 30 days for any incident meeting the 171.15 criteria. If the property damage estimate comes back over $50,000, that report becomes mandatory even though nothing at the scene looked reportable.
Evidence and paperwork:
- Preserve the shipping paper and the emergency response information as they existed at the time of the incident. Do not "fix" them afterward.
- Preserve the placards and package labels as they were.
- Note the sequence of events, times, and who you spoke to while it is fresh.
- Cooperate fully with the carrier's investigation and the responding agencies.
Finally, ask the honest question: were the drums properly closed, blocked, and braced, and were the labels intact? If the answer is anything other than a clear yes, that is a fact your carrier needs from you before the investigator finds it in the photographs.
