6.1 Mandatory Report Components under 40 CFR 745.227(d)(11) and HUD Chapter 5
Statutory Basis and Administrative Framework
The compilation of a lead risk assessment report represents the culmination of field evaluations, visual inspections, background investigations, and environmental sample analysis. Under federal law, the lead risk assessment report is a legal document that establishes whether lead-based paint hazards exist within target housing or child-occupied facilities, defines the scope of required hazard controls, and dictates seller/landlord disclosure obligations under Section 1018 of Title X (40 CFR Part 745 Subpart F / 24 CFR Part 35 Subpart A).
Regulatory requirements for report content are established by the U.S. Environmental Protection Agency (EPA) under 40 CFR § 745.227(d)(11) and supplemented by the U.S. Department of Housing and Urban Development (HUD) in Chapter 5 of the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing. A risk assessment report that lacks any mandatory regulatory component fails to satisfy federal compliance standards and exposes the certified firm and certified risk assessor to administrative enforcement actions, civil monetary penalties, and license revocation.
Mandatory Report Elements under 40 CFR 745.227(d)(11)
Federal regulations under 40 CFR § 745.227(d)(11) mandate that a certified risk assessor must prepare a written report for every risk assessment conducted. The report must be delivered to the client who ordered the evaluation and retained in the assessor's permanent files. Section 745.227(d)(11) explicitly requires the inclusion of fifteen core structural elements:
| Report Section | Regulatory Citation | Required Technical Contents & Compliance Verification |
|---|---|---|
| Administrative & Assessor Identification | 40 CFR 745.227(d)(11)(1)-(2) | Date of assessment, property owner name/address/phone, certified risk assessor legal name, signature, EPA/state certification number, certified firm name, address, and firm license number. |
| Property Profile & Construction History | 40 CFR 745.227(d)(11)(3) | Exact physical address, building identification, specific unit numbers evaluated, and verified date of construction (pre-1978 target housing determination). |
| Occupant Demographics & EBLL History | 40 CFR 745.227(d)(11)(4) | Resident profile including presence of children under age 6, pregnant women, occupation/hobbies involving lead, and documented history of elevated blood lead level (EBLL) investigations. |
| Visual Assessment & Physical Condition | 40 CFR 745.227(d)(11)(5) | Comprehensive physical description of building condition, structural defects, moisture leaks, paint condition (intact, fair, poor), location, and substrate composition across all room equivalencies. |
| Background & History of Lead Activities | 40 CFR 745.227(d)(11)(6) | Historical record of prior lead inspections, risk assessments, abatements, interim controls, or structural renovations performed at the target property. |
| Sampling Locations & Measurement Logs | 40 CFR 745.227(d)(11)(7)-(9) | Detailed floor plan sketches, precise sample location descriptions, XRF instrument serial number, radioactive source age, calibration logs, dust wipe field dimensions (sq ft or sq in), and soil sample composite profiles. |
| Laboratory Analysis & Quality Assurance | 40 CFR 745.227(d)(11)(10) | Accredited laboratory name, NLEAP/AIHA certification number, test methods (FAAS, ICP-AES), Chain of Custody (COC) records, field blank values, and raw analytical data expressed in µg/ft², mg/cm², or ppm. |
| Hazard Identification Matrix | 40 CFR 745.227(d)(11)(11) | Explicit identification of all lead-based paint hazards (deteriorated lead paint, lead-contaminated dust, bare lead soil) cross-referenced against federal standards (40 CFR § 745.65). |
| Hazard Control Recommendations | 40 CFR 745.227(d)(11)(12) | Prioritized, site-specific hazard reduction options detailing both interim controls and abatement measures for every identified lead hazard. |
| Re-evaluation & Maintenance Schedule | 40 CFR 745.227(d)(11)(13) | Recommended schedule for ongoing maintenance, visual monitoring, and periodic re-evaluations to ensure interim controls remain intact. |
HUD Guidelines Chapter 5: Multi-Family and Public Housing Protocols
For public housing authorities (PHAs) and federally assisted housing governed by the HUD Lead Safe Housing Rule (24 CFR Part 35), HUD Chapter 5 establishes specialized reporting requirements beyond the EPA 40 CFR 745.227(d)(11) baseline.
Multi-Family Housing Aggregation
In multi-family developments where random targeted sampling is conducted across similar units, the risk assessment report must document the statistical sampling plan methodology. The report must contain:
- Complete list of all units in the building complex categorized by building number and unit size.
- Identification of randomly selected target units sampled (e.g., units occupied by children under 6 or units in worst physical condition).
- Clear statement establishing that lead hazards identified in sampled units are legally imputed to all unsampled units within the same targeted building component group.
Visual Assessment Integration & Substrate Defect Mapping
HUD Chapter 5 requires rigorous documentation of physical building integrity. The assessor must evaluate and report structural causes of paint failure:
- Moisture Intrusion: Roof leaks, plumbing failures, window sill condensation, masonry water intrusion.
- Substrate Failure: Rotting wood trim, crumbling plaster, failing drywall, rusting metal.
- Friction and Impact Dynamics: Binding doors, tight window sashes, colliding door frames, uncarpeted stair treads subject to foot traffic.
Technical Documentation of Environmental Data
A legally defensible risk assessment report relies on unassailable analytical documentation. Raw data must be rendered transparently within the report body or attached as formal appendices:
- XRF Instrumentation Testing Logs: Must record the XRF manufacturer, model, serial number, radioactive isotope type (Cadmium-109 or Cobalt-57), isotope source date, and initial/mid-day/end-of-day calibration check readings (must fall within +/- 0.1 mg/cm² of the 1.0 mg/cm² NIST standard film).
- Dust Wipe Sample Calculations: Dust wipe wipe areas measured in square inches must be converted to square feet using the standard conversion formula:
Area in sq ft = (Area in sq in) / 144The report must present final concentrations in µg/ft² alongside field blank analytical results to verify laboratory background purity. - Soil Sample Profiles: Composite soil samples must detail the exact number of sub-samples collected (3 to 10 subsamples per composite), collection depth (top 0.5 inch), and precise location (child play area vs building perimeter/drip line), reported in ppm or mg/kg.
Final Executive Summary and Hazard Control Matrix
To ensure property owners, maintenance staff, and tenants can interpret technical findings, 40 CFR 745.227(d)(11) requires a concise, non-technical executive summary at the front of the report. This summary must list all identified lead-based paint hazards, rank their severity, specify immediate interim control actions, and present long-term abatement options. The certified risk assessor must sign and date the report, certifying under penalty of law that the evaluation adhered to federal work practice standards under 40 CFR Part 745 Subpart L.
Under 40 CFR 745.227(d)(11), which individual's signature and certification number must appear on the final lead risk assessment report?
When dust wipe samples are collected during a risk assessment, how must sample wipe dimensions measured in square inches be converted to square feet for reporting in µg/ft²?
Under HUD Chapter 5 guidelines for multi-family target housing assessments, how are lead hazards identified in a representative sample of targeted units treated regarding unsampled units?
Which of the following is a mandatory report element required under 40 CFR 745.227(d)(11)(12)?
