Background and Regulatory Framework for Lead-Based Paint Activities
Why a Regulatory Framework Exists
Lead-based paint (LBP) activities in target housing and child-occupied facilities are regulated because lead hazards are invisible and cumulative. The candidate must know the statutory backbone: the Toxic Substances Control Act (TSCA) Title IV authorized EPA's lead program, and the Residential Lead-Based Paint Hazard Reduction Act of 1992 (Title X) reframed the goal from merely identifying lead paint to controlling lead hazards. EPA's implementing rule (40 CFR Part 745) defines key terms, sets certification and training requirements, and establishes work practice standards.
Key Definitions and Concepts
- Target housing: housing constructed before 1978, with limited statutory exclusions (e.g., housing for the elderly or disabled, unless a child under six resides).
- Child-occupied facility: visited regularly by the same child under six, on at least two different days per week, with at least 6 hours total per week.
- Lead-based paint: paint or coating with lead at or above 1.0 mg/cm², or 0.5% by weight.
- Abatement vs. interim controls: abatement is a permanent elimination of the hazard (removal, enclosure, encapsulation, replacement); interim controls are temporary.
- Certified inspector vs. risk assessor: the inspector performs paint, dust, and soil sampling and identifies hazards; the risk assessor determines the existence, cause, and severity of hazards and recommends response actions.
Traps in Questions
Watch for the 1978 cutoff being confused with 1960 or 1950; the 6-hour/2-day child-occupied facility threshold; and the distinction between a clearance exam and an inspection. Also note that state programs may be authorized to run the program in place of EPA, so the correct answer may reference the authorized state.
Rule of Thumb
If a building is pre-1978 and a child under six spends regular time there, assume the framework applies until proven otherwise.
