Section 1: Federal Lead Laws & Regulations (TSCA Title IV, RRP
Rule, HUD Guidelines) (Q1-18)
Q1. Under the Toxic Substances Control Act (TSCA) Title IV, Section 402, what is the
federal definition of lead-based paint (LBP)?
A. Paint containing more than 0.5 mg/cm² of lead by XRF measurement
B. Paint containing more than 1.0 mg/cm² of lead, or more than 0.5% lead by weight
C. Paint containing any detectable amount of lead
D. Paint containing more than 5.0% lead by weight
Rationale: Federal LBP definition: >1.0 mg/cm² by XRF or >0.5% lead by weight
(dry weight). Option A uses the wrong threshold. Option C is false—EPA has specific
thresholds. Option D uses an outdated, higher threshold.
Correct Answer: B
Q2. A renovation firm is hired to replace windows in a pre-1978 single-family home
where a child under 6 resides. Under the EPA RRP Rule (40 CFR 745.80-745.99), which
certification is REQUIRED for the firm?
A. OSHA 10-Hour Construction certification only
B. EPA RRP Firm Certification and at least one EPA Certified Renovator on site
C. State contractor license only
D. HUD Lead Inspector certification
Rationale: The RRP Rule requires EPA Firm Certification AND at least one EPA
Certified Renovator assigned to the job who can perform critical tasks (posting
,signs, containment, waste handling). OSHA 10 (Option A) is unrelated. State license
(Option C) is insufficient. HUD certification (Option D) is different from RRP.
Correct Answer: B
Q3. Under the RRP Rule, what is the minimum distance that warning signs must be
posted from the work area perimeter?
A. 5 feet
B. 10 feet
C. 20 feet
D. 50 feet
Rationale: RRP Rule requires warning signs posted at the perimeter of the work
area and at entries to the work area, visible to occupants. The signs must define the
work area boundary. While the rule specifies signs at the perimeter, the practical
standard is 20 feet from the work area or at the perimeter of the containment area.
Actually, the RRP Rule states signs must be posted at the perimeter of the work area.
Let me verify: 40 CFR 745.85 requires signs at the perimeter of the work area. The "20
feet" is often cited in training as a practical guideline for visibility. However, the
regulation states "at the perimeter." Let me be precise.
The RRP Rule (40 CFR 745.85) states: "Post signs clearly defining the work area and
warning occupants and other persons not involved in the renovation to remain
outside of the work area." The signs must be posted at the perimeter. For the exam,
the most accurate answer based on common training materials is that signs define
the perimeter. I'll use a clear regulatory answer.
Revised options:
A. 5 feet from the work area
B. At the perimeter of the work area, clearly visible to occupants
C. 50 feet from the work area
D. Only at the front door of the building
Rationale: The RRP Rule (40 CFR 745.85) requires signs to be posted at the
perimeter of the work area to clearly define the boundary and warn occupants.
,There is no specific foot distance mandated—signs must simply define the work area
perimeter. Options A, C, and D are either arbitrary distances or insufficient
placement.
Correct Answer: B
Q4. Under HUD's Lead Safe Housing Rule (24 CFR 35), which housing is covered by
the requirement to conduct lead hazard reduction activities?
A. All housing built before 1978, regardless of federal funding
B. Federally owned housing and housing receiving federal assistance, built before
1978, where a child under 6 resides or is expected to reside
C. Only public housing authorities
D. Only housing built before 1960
Rationale: HUD's Lead Safe Housing Rule applies to federally owned or assisted
pre-1978 housing where children under 6 live or are expected to live. It does not
cover all pre-1978 housing (Option A)—only federally involved housing. Option C is
too narrow. Option D uses an incorrect date.
Correct Answer: B
Q5. Under TSCA Section 406, what action must EPA take regarding lead-
contaminated dust hazards?
A. Ban all lead-based paint immediately
B. Identify and publish hazard standards and alert the public to dangers of lead-
based paint
C. Provide free lead testing to all homeowners
D. Mandate lead abatement in all pre-1978 housing
Rationale: TSCA Section 406 requires EPA to publish lead hazard standards (dust,
soil) and inform the public about lead-based paint dangers. It does not ban all LBP
, (Option A), provide free testing (Option C), or mandate universal abatement (Option
D).
Correct Answer: B
Q6. An EPA Certified Renovator is performing window replacement in a pre-1978
apartment. Under the RRP Rule, which work practice is REQUIRED before beginning
the renovation?
A. Notify the EPA 30 days in advance
B. Provide the occupant with EPA's "Renovate Right" pamphlet before renovation
begins
C. Obtain a building permit only
D. Hire a third-party inspector to pre-test all surfaces
Rationale: The RRP Rule requires renovators to provide occupants with the
"Renovate Right" (RRP) pamphlet (protecting families from lead hazards) before
renovation begins and obtain confirmation of receipt. EPA notification (Option A) is
not required for standard renovations. Building permits (Option C) are local
requirements. Pre-testing (Option D) is not required under RRP.
Correct Answer: B
Q7. Under 40 CFR 745.85, what is the minimum containment requirement for interior
renovation work that disturbs more than 6 square feet of lead-based paint surface?
A. No containment is required for interior work
B. Vertical containment extending from the floor to the ceiling, sealed with tape, and
covering all objects in the work area
C. A drop cloth on the floor only
D. Plastic sheeting extending 6 feet horizontally from the work area in all directions
Rationale: The RRP Rule requires vertical containment (floor-to-ceiling plastic
sheeting) for interior work, sealed with tape, with all objects in the work area
