What 172.205A-HMSP means in plain language
When you transport hazardous waste, federal law requires specific documentation to travel with your load. This citation is issued when you operate a vehicle carrying hazardous waste but fail to maintain the manifest exactly as required by EPA regulations (40 CFR 262.20).
The manifest is not optional—it's a legal chain-of-custody document that tracks hazardous waste from generator to disposal facility. It must be present, accurate, and properly completed before you operate the vehicle. Missing pages, unsigned sections, incomplete shipper information, or failure to carry it on board all constitute violations of this requirement.
This is different from general hazmat placarding or loading violations. This code specifically addresses the paperwork that proves you're legally authorized to transport that hazardous waste and that the waste destination is legitimate and permitted.
What our enforcement data actually shows
Across 13 million inspections in our database, this code is rarely cited. All-time, we have recorded 2 citations for 172.205A-HMSP, with 1 citation in the last 12 months and 0 in the last 90 days. The out-of-service rate for this code is 0.0%—none of the 2 carriers cited were removed from service.
For context, the all-FMCSR average out-of-service rate is 31.4%. This code ranks #2651 of 3,036 FMCSR codes by citation volume, placing it in the lowest-citation tier. The single citation in the last 12 months occurred in May 2025.
The low enforcement volume does not mean the requirement is unimportant. It reflects that most hazmat carriers understand and comply with manifest requirements, likely due to the serious nature of hazardous waste transportation and the EPA oversight that accompanies it. When citations do occur, they typically don't result in roadside out-of-service placement—inspectors document the violation but allow the driver to correct and proceed in many cases.
Who gets cited most
Our inspection records show only two carriers with citations for this code. Propane West Coast LLC (USDOT 3469978) and Christian Marcel Trejo Ochoa (USDOT 4031530) each have 1 citation in our all-time database. The cited vehicles were a Chevrolet and a Ford—both common makes in commercial service.
With only 2 total citations across millions of inspections, geographic or carrier-specific patterns are not meaningful. This code appears to affect a very small population of violators, suggesting that hazardous waste shippers and carriers have strong compliance incentives and training infrastructure.
How severe is this compared to similar codes
This citation sits within the broader hazardous materials category, but manifest documentation violations are distinct from loading, placarding, and emergency response violations.
Our data shows that peer codes in hazmat enforcement see far higher citation volumes and out-of-service rates. For example, general loading and unloading violations (177.834A-HMC) have 3,954 citations with a 99.2% out-of-service rate, and placarding violations (177.817(a)) have 2,274 citations with a 75.1% out-of-service rate. Even maintenance of emergency response information (172.602(c)(1)) has 1,464 citations, though it shares the same 0.0% out-of-service rate as 172.205A-HMSP.
The 0.0% out-of-service rate is unusual within hazmat enforcement. It suggests that when manifest documentation defects are found, they are often correctable on the spot or the driver is issued a citation without removal from service, provided the shipment is legitimate and the vehicle is otherwise safe.
How to avoid it
Manifest compliance is straightforward if you follow these pre-trip and during-transport steps:
-
Verify the manifest before departure. Check that every required field is completed: generator name and EPA ID, transporter information, waste description, quantity, and destination facility details. Do not depart if any section is blank or illegible.
-
Confirm the manifest matches your load. Cross-reference the waste description and quantity on the manifest against the actual containers and placards on your vehicle. A mismatch is a red flag and grounds for refusal to transport.
-
Keep the manifest in the cab and accessible. During a roadside inspection, you must be able to produce it immediately. Do not store it in a locked trailer or hard-to-reach compartment.
-
Never transport hazardous waste without a manifest. Even a partial load or a small container requires full documentation. "Just running to the disposal site" or "making a quick delivery" does not exempt you from manifest requirements.
-
Ensure the manifest is signed by all required parties before pickup. The generator and transporter signatures must be present. If a signature is missing, do not accept the load—contact the shipper.
-
Request clarification if the manifest is unclear. If shipper instructions, EPA numbers, or destination information are ambiguous, ask for corrected documentation. Proceeding with an unclear manifest invites citation.
-
Understand your role in the chain of custody. As a transporter, you are part of a federal tracking system. Your part is custody and accurate delivery—treat the manifest as a legal document, not an administrative formality.
