How long must a "Declaration of Inspection"...

How long must a "Declaration of Inspection" be kept on board?

🔍 Key Concepts

• Declaration of Inspection (DOI) requirements for oil or hazardous material transfers • Recordkeeping and retention periods in 33 CFR Part 156 (Oil and hazardous material transfer operations) • Difference between how long a DOI is valid for a transfer vs. how long it must be kept on board after completion

💭 Think About

• Look up the specific CFR section that talks about the contents and handling of a Declaration of Inspection and see if it also states a retention period. • Ask yourself: is the DOI a short‑term operational checklist, or is it treated like an official record that must be available for inspection later? That affects how long it is kept. • Compare the answer choices with typical Coast Guard recordkeeping periods for similar documents (hours, days, weeks, months). Which length best matches an inspection‑type record rather than a daily log entry?

✅ Before You Answer

• Verify in 33 CFR Part 156 (especially sections around DOI requirements) exactly how long a completed DOI must be retained on board. • Confirm that you are not confusing the time before/after transfer that the DOI must be completed with the time it must be kept on file. • Make sure the period you choose is explicitly stated as a minimum retention time and not just an operational validity period.
