OSHA Citation vs De Minimis Response Protocol

Why this matters

An OSHA inspection ends one of three ways: no citation issued, a notice of de minimis violation (no penalty, no posting requirement, often not even a written document), or a Citation and Notification of Penalty issued under 29 CFR 1903.14. The window to respond to a citation is 15 working days from receipt per 29 CFR 1903.17. Miss it and the citation becomes a final order that cannot be contested, the penalty is owed, and the abatement clock is locked. This SOP gives you the response sequence that preserves every legal right.

Step 1 - read the document before you react

A citation is a formal document with specific structure. Identify before anything else:

• The Citation number and issue date
• Each individual citation item, classified as Other-Than-Serious, Serious, Repeat, Willful, or Failure-to-Abate per 29 CFR 1903.14(b)
• The cited standard for each item (the CFR section, for example 29 CFR 1926.501(b)(13))
• The alleged violation description for each item
• The proposed penalty per item (penalty caps are inflation-adjusted under 29 CFR 1903.15; the current maximums are posted at osha.gov/penalties)
• The abatement date for each item
• The 15-working-day contest deadline
• The address of the area director for the informal conference request

A de minimis notice is different. Per OSHA Field Operations Manual chapter 4, de minimis is a violation that has no direct or immediate relationship to safety or health. There is no penalty, no posting requirement, no abatement requirement that gets verified, and it does NOT count as a prior citation for repeat-violation calculation. If what you received is a de minimis notice, file it and move on; there is nothing else to do.

Step 2 - calendar every deadline

Working days excludes Saturday, Sunday, and federal holidays. Day 1 is the day AFTER receipt. The 15-working-day clock applies to:

• Filing a written Notice of Contest with the area director
• Requesting an informal conference (the conference does NOT toll the contest deadline; you must file Notice of Contest or settle by day 15 even if the conference is later)
• Petitioning for modification of abatement date (PMA) if you cannot abate by the cited date

Mark every date on a master calendar and a backup calendar. Send the Notice of Contest by certified mail with return receipt; date-of-mailing controls for filing purposes per 29 CFR 1903.17.

Step 3 - post the citation immediately

Per 29 CFR 1903.16, the citation must be posted at or near the location of the alleged violation, in plain sight, for three working days OR until the violation is abated, whichever is longer. Post on day of receipt. Do NOT redact or modify the document. Take a date-stamped photograph of the posting and save it; an inspector returning for follow-up will verify posting compliance.

If the cited location is a mobile job site that no longer exists, post at the establishment where the affected employees report. Multi-site businesses must post a copy at each affected establishment.

Step 4 - request the informal conference

For most citations the informal conference with the OSHA area director is the highest-value step. It is requested in writing within 15 working days but commonly scheduled past that date. Filing the request does NOT extend the contest deadline. Best practice: file the Notice of Contest as a preserver on day 13 or 14, then proceed with the conference. You can always withdraw the contest after settling.

At the conference you can:

• Present evidence the violation did not exist or did not apply
• Argue for reclassification (Serious to Other-Than-Serious, Willful to Serious)
• Argue for penalty reduction based on size, good faith, history, gravity
• Negotiate abatement-date extensions
• Negotiate withdrawal of specific items in exchange for not contesting others

The area director can sign an Informal Settlement Agreement that becomes binding when both parties sign and is NOT a final order subject to further contest.

Step 5 - decide contest, settle, or accept

By day 15:

• ACCEPT - pay the penalty and abate by the abatement date. Citation becomes a final order. Counts as prior history for repeat purposes for five years.
• SETTLE - sign the informal settlement; pay reduced penalty per the settlement.
• CONTEST - file written Notice of Contest with the area director by certified mail. This sends the case to the Occupational Safety and Health Review Commission for formal adjudication.

A Notice of Contest can be specific (contest only one item, or only the penalty, or only the classification) or full (contest everything). Be specific - contesting only what you actually dispute keeps the rest from being tied up.

Step 6 - abate and certify

Each cited item has an abatement date. Per 29 CFR 1903.19, employers must submit certification of abatement within ten calendar days after the abatement date. Serious, Willful, Repeat, and Failure-to-Abate citations also require abatement documentation showing what was actually done. Include:

• Description of the corrective action
• Date completed
• Photographic evidence where physical conditions were involved
• Written training records where the abatement was procedural
• Signature of an officer of the company

A failure-to-abate citation under 29 CFR 1903.14(c) is calculated per day past the abatement date, so missing this is expensive. If you cannot meet the date, file a PMA before the date passes.

Step 7 - control the post-citation footprint

A served citation enters OSHA's enforcement database. For five years from the final-order date, it can be cited as the prior violation supporting a Repeat classification under 29 CFR 1903.14(b), where Repeat carries the same maximum as Willful per 29 CFR 1903.15. Repeats can be issued company-wide for the same standard at any establishment, not just the cited site. Mitigation: complete the abatement, train the affected employees, document, and update your IIPP or written program to address the root cause.
