Section A: Regulatory Framework & Legal Requirements
Q1: Under which federal authority does EPA administer the Lead-Based Paint Activities
Program?
A. Clean Air Act Section 108
B. TSCA Section 402/404 [CORRECT]
C. CERCLA Section 104
D. SDWA Section 1412
Correct Answer: B
Rationale: EPA's Lead-Based Paint Activities Program operates under the Toxic
Substances Control Act (TSCA) Sections 402 and 404, codified at 40 CFR Part 745
Subpart L. The Clean Air Act, CERCLA, and SDWA do not govern lead inspector
certification.
Q2: What is the minimum total training hour requirement for an accredited Lead
Inspector course?
A. 16 hours
B. 20 hours
C. 24 hours [CORRECT]
D. 32 hours
Correct Answer: C
Rationale: 40 CFR Part 745 Subpart L requires a minimum of 24 training hours for Lead
Inspector certification, including at least 8 hours of hands-on training. Options A, B, and
D do not meet the federal minimum.
,Q3: How many hands-on training hours must be included in an accredited Lead
Inspector course?
A. 4 hours
B. 6 hours
C. 8 hours [CORRECT]
D. 12 hours
Correct Answer: C
Rationale: The EPA accreditation standards mandate at least 8 hours of hands-on
training within the 24-hour Lead Inspector course. Options A and B fall short, and option
D exceeds the minimum but is not the required floor.
Q4: What is the minimum passing score for the EPA third-party Lead Inspector
certification exam?
A. 60%
B. 65%
C. 70% [CORRECT]
D. 75%
Correct Answer: C
Rationale: The EPA third-party certification exam requires a minimum score of 70% to
pass. Options A and B are below the threshold, and option D, while achievable, is not the
minimum required passing score.
Q5: How long is an EPA Lead Inspector certification valid before renewal is required?
A. 3 years
B. 5 years [CORRECT]
C. 7 years
D. 10 years
Correct Answer: B
,Rationale: EPA Lead Inspector certification is valid for 5 years, after which an 8-hour
refresher course is required for renewal. Option A reflects older or incorrect state
programs, while options C and D exceed federal validity periods.
Q6: What is the minimum educational prerequisite to become a certified Lead
Inspector?
A. Associate degree in environmental science
B. Bachelor's degree in any field
C. High school diploma or equivalent [CORRECT]
D. No formal education required
Correct Answer: C
Rationale: EPA regulations require only a high school diploma or equivalent for Lead
Inspector certification; no additional college education or experience is required.
Options A and B exceed requirements, and option D is below the minimum.
Q7: According to 40 CFR Part 745, what is the lead concentration threshold that defines
lead-based paint using laboratory analysis?
A. 0.1% by weight
B. 0.3% by weight
C. 0.5% by weight [CORRECT]
D. 1.0% by weight
Correct Answer: C
Rationale: Lead-based paint is defined as paint containing lead equal to or greater than
0.5% by weight (5,000 ppm) via laboratory analysis, or 1.0 mg/cm² via XRF. Option D
confuses the XRF threshold with the laboratory threshold.
Q8: What is the XRF threshold that defines a surface as containing lead-based paint?
A. 0.5 mg/cm²
B. 0.8 mg/cm²
C. 1.0 mg/cm² [CORRECT]
D. 1.5 mg/cm²
, Correct Answer: C
Rationale: Under EPA regulations, an XRF reading of 1.0 mg/cm² or greater defines
lead-based paint. Option A is the laboratory analysis threshold, and options B and D are
not federally defined limits.
Q9: Under 40 CFR 745.65, what is the federal dust-lead hazard standard for floors?
A. 5 µg/ft²
B. 10 µg/ft² [CORRECT]
C. 20 µg/ft²
D. 40 µg/ft²
Correct Answer: B
Rationale: The federal dust-lead hazard standard for floors is 10 µg/ft². Option A is
below the hazard threshold, option C is not the federal standard, and option D is the
post-abatement clearance level, not the hazard standard.
Q10: What is the federal dust-lead hazard standard for interior window sills?
A. 50 µg/ft²
B. 80 µg/ft²
C. 100 µg/ft² [CORRECT]
D. 250 µg/ft²
Correct Answer: C
Rationale: The federal dust-lead hazard standard for interior window sills is 100 µg/ft².
Option D is the clearance level for window sills, while options A and B are not federally
recognized hazard standards.
Q11: What is the federal soil-lead hazard standard for play areas?
A. 200 ppm
B. 400 ppm [CORRECT]
C. 800 ppm
D. 1,200 ppm
