3.4 HUD Guidelines and Other Documented Methodologies

HUD Guidelines and Other Documented Methodologies

Quick answer: 745.227(a)(3) tells you which documented methodologies are appropriate when Subpart L says to sample, test, or select locations “according to documented methodologies.” The list is the HUD Guidelines, two EPA residential guidance/sampling documents (including EPA 747-R-95-001), authorized State or Tribal methods, and other equivalent methods. HUD Guidelines are not a substitute for 745.227. They are the field manual for doing what 745.227 already requires.

The exam loves two mistakes: treating HUD as optional color commentary, and treating HUD as a higher law that lets you skip notification, the 2-hour supervisor rule, or action levels. Both are wrong.

What 745.227(a) actually says

745.227(a)(1) made the work practice standards effective beginning March 1, 2000. (a)(2) says that when a certified individual performs an activity described as an inspection, lead-hazard screen, risk assessment, or abatement, that person must comply with the appropriate requirements below. Then (a)(3) names the methodologies:

1. HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing
2. EPA Guidance on Residential Lead-Based Paint, Lead-Contaminated Dust, and Lead-Contaminated Soil
3. EPA Residential Sampling for Lead: Protocols for Dust and Soil Sampling (EPA report number 747-R-95-001)
4. Regulations, guidance, methods, or protocols issued by States and Indian Tribes that have been authorized by EPA
5. Other equivalent methods and guidelines

745.223 defines documented methodologies as methods or protocols used to sample for the presence of lead in paint, dust, and soil. That sampling focus matters. HUD Chapters on containment and abatement methods still show up because the Guidelines are a single manual: they tell a supervisor how to control the lead the sampling protocols will later measure.

Whenever 745.227 says “using documented methodologies” it is pointing at this list. Examples:

• Inspection (745.227(b)): selecting components with a distinct painting history; paint analysis with adequate quality control.
• Risk assessment (745.227(d)): which friction/impact/deteriorated surfaces to test; dust and soil sampling locations; quality control.
• Post-abatement testing (745.227(e)(8)): dust samples taken with documented methodologies; rooms selected according to documented methodologies; minimum 1 hour after final cleanup before sampling.
• Determinations (745.227(h)): comparing results to LBP, hazard, and action-level definitions — the numbers are in the CFR; the wipe, XRF, and soil protocols are in the methodologies.

Adequate quality control (745.223) means a plan that protects authenticity, integrity, and accuracy of dust, soil, and paint-chip samples, including representative sampling. A methodology that skips blanks, spike recovery, or representative locations is not “documented” just because someone photocopied a HUD chapter title onto the chain-of-custody.

HUD Guidelines vs. 745.227 — who wins

If HUD Chapter 8 describes a containment detail that helps you meet 745.227, use it. If a toolbox talk says “HUD doesn’t mention 5-day notice, so we can start tomorrow,” fire the talk. Guidance implements the rule. It does not amend the Code.

On HUD-assisted housing, 24 CFR Part 35 (Lead Safe Housing Rule) can impose additional evaluation and hazard-reduction duties. Those HUD regulatory duties are not “just Guidelines.” Do not confuse HUD Guidelines (methodology) with the Lead Safe Housing Rule (regulation for assisted housing). A public-housing abatement can be under both 40 CFR 745 Subpart L (or the authorized State) and 24 CFR 35.

Why HUD Chapter 8 and Chapter 12 appear on the exam

The HUD Guidelines are organized as a field manual. Two chapters are exam fixtures for supervisors:

Chapter 8 — Resident Protection and Worksite Preparation (containment). This is the usual source for:

• Whether occupants are relocated or remain with isolated work areas
• Warning signs at the regulated area
• Critical barriers on doors, windows, and HVAC openings
• Polyethylene floor sheeting and furniture covering or removal
• Shutting down or isolating HVAC so dust is not ducted through the building
• Exterior ground sheeting and, when needed, vertical containment
• Daily cleanup so lead dust does not leave the containment on shoes, tools, or the wind

745.223 defines containment as a process to protect workers and the environment by controlling exposures to the lead-contaminated dust and debris created during an abatement. The CFR requires containment as part of doing abatement safely; Chapter 8 is how most courses teach the plastic, tape, and barrier details.

Chapter 12 — Abatement. This is the usual source for method-level pictures of:

• Component replacement
• Enclosure (rigid, durable, mechanically fastened — matching the 745.223 enclosure definition)
• Encapsulation (and why friction, impact, chewable, or deteriorating surfaces are poor candidates)
• Paint removal (wet scraping, chemical removal, heat guns below the 1100°F federal cap)
• Integrating final cleaning so the inspector or risk assessor is not sampling visible dust

Cleaning sequences (HEPA vacuum, wet wash, HEPA again) and clearance sampling plans also live in later HUD chapters. Courses still call the package “HUD 8 and 12” because those two chapters are where containment geometry and method selection are taught. If an item asks how to sheet an exterior or whether grass counts as permanent soil covering, you are in HUD-plus-745.223 territory: permanently covered soil requires pavement or concrete, not grass or mulch.

How a supervisor uses methodologies on a real job

Reading the risk assessment. A certified risk assessor (not the supervisor, unless the supervisor also holds that discipline) identifies hazards and recommends interim controls and/or abatement options, with a suggested priority, and a maintenance schedule if encapsulant or enclosure is recommended (745.227(d)(11)). The supervisor’s job is to turn that report into a work plan and occupant protection plan that 745.227(e) will survive:

• Which components are LBP vs. below the definition
• Which hazards are paint, dust, or soil
• Which recommended option is actually abatement (permanent) versus interim control (temporary) — interim controls are not abatement (745.223)
• Whether soil is a play-area 400 ppm problem or rest-of-yard 1,200 ppm problem (745.227(h)(4))

If the risk assessor sampled dust with HUD/EPA wipe protocols and reported floors at a reportable level, that is already a dust-lead hazard on/after January 12, 2026. Abatement of that dust still has to finish below the 5/40/100 action levels. Do not read “hazard = any reportable level” as “we can never complete abatement.” Completion is the action-level test; the hazard statement covers leftover reportable dust below those levels (Chapter 18).

Choosing sampling and cleaning. The supervisor designs cleaning so the inspector or risk assessor can sample. 745.227(e)(8) and (f) are strict: post-abatement dust sampling is performed only by a certified inspector or risk assessor; samples go to an EPA-recognized laboratory (TSCA 405(b)); dust samples wait at least 1 hour after final cleanup; rooms are selected according to documented methodologies. You do not “HUD-wipe” your own clearance to save a fee unless you also hold the inspector/risk assessor certification and the firm arrangement is independent enough to be honest. Fail a sample and you reclean and retest the components it represents — another 745.227 rule HUD cleaning chapters merely illustrate.

Authorized-state methods. 745.227(a)(3) expressly allows methodologies issued by EPA-authorized States and Tribes. In an authorized State, the State sampling SOP may be the documented methodology you must use. It still cannot undercut the State’s own work-practice standards, which had to be at least as protective as Subpart L.

OSHA 1926.62 is a parallel duty, not a methodology

OSHA 1926.62 is not on the 745.227(a)(3) list. It does not tell you how to take a floor wipe for EPA action levels. It does tell you that employees on the abatement have a 50 µg/m³ PEL, a 30 µg/m³ action level, exposure assessment, respirators, hygiene facilities, and medical surveillance. A containment that satisfies HUD Chapter 8 can also help keep OSHA exposures down, but passing OSHA air monitoring does not clear EPA dust-lead action levels, and passing clearance wipes does not satisfy OSHA. Preview only; Chapter 16 is the full worker-protection syllabus.

Field rule

When the exam or the job asks “what methodology,” name a 745.227(a)(3) source and then apply the mandatory 745.227 paragraph that triggered the sampling or work practice. HUD Chapter 8 for how to contain. HUD Chapter 12 for how to abate a component. 745.227 for whether you were allowed to start, who had to be on site, and whether you are done.
