If your shop sprays coatings containing certain hazardous air pollutants, you're likely subject to the EPA's "6H" rule — formally NESHAP 40 CFR Part 63 Subpart HHHHHH. Beyond the equipment requirements, a big part of staying in good standing is simply having the right paperwork ready when an inspector asks. This is a plain-English checklist of the records shops commonly keep. It's informational only and not legal advice — the exact requirements depend on the current rule text and your local authority having jurisdiction (AHJ), so confirm specifics with your regulator or a compliance professional.
First, the equipment side (so the records make sense)
Per the EPA's rule, spray booths, prep stations, and mobile enclosures generally must use filter technology demonstrated to capture at least 98% of paint overspray (measured by a recognized method such as ANSI/ASHRAE 52.2 or EPA Method 319). Intake filters in many wall/ceiling assemblies are also expected to be UL 900 listed under NFPA 33. The records below mostly exist to prove your equipment and people meet those expectations.
The recordkeeping checklist
Shops subject to 6H commonly keep the following on file:
- Filter efficiency documentation. Manufacturer data sheets or certificates showing your exhaust/overspray filters meet the ≥98% capture standard. Keep the docs for the specific filters you actually buy and use.
- Painter training certificates. Documentation that each person who sprays has completed the required training, with dates. Track refresher/renewal dates so none lapse.
- Initial notification. A copy of the notification submitted to your regulator identifying your facility as subject to the rule.
- Notification of compliance status. The record stating your facility meets the rule's requirements.
- Equipment records. Documentation of the spray equipment and booth/filtration setup you use to comply (for example, HVLP or equivalent gun records, booth/filter specs).
- Filter change records. A simple log of when filters were replaced helps demonstrate ongoing maintenance and proper operation.
Make it easy to produce on request
The records only help if you can find them. A few habits that keep shops out of trouble:
- Keep a single binder or folder (paper or digital) with the notifications, training certs, and filter efficiency docs together.
- File the spec sheet every time you buy filters. When you reorder, save the current manufacturer documentation — formulations and certifications can change over time.
- Log filter changes where the booth is. A whiteboard or notebook at the booth, transferred to your records, keeps the change history honest.
- Track training expiration dates on a calendar so you renew before they lapse, not after.
- Retain records for the required period. Confirm the current retention timeframe with your regulator and don't toss anything early.
A note on filter purchases
Buying from a supplier who provides the manufacturer's capture-efficiency and UL listing documentation makes this whole process easier — you get the paperwork you need to keep on file at the same time you get the filter. A "deal" filter with no documentation can leave a gap in your records.
The bottom line
Compliant equipment is half the job; provable compliance is the other half. Keep filter efficiency docs, training certificates, your notifications, and a filter-change log together and current, and an inspection becomes a paperwork formality instead of a scramble. Again — this is general guidance, not legal advice. Verify the current requirements with your AHJ.
