When disturbing painted surfaces in a building built in 1968, what is the minimum area of paint disturbance that triggers EPA RRP (Renovation, Repair, Painting) Rule requirements?
Correct Answer
B) 6 square feet interior, 20 square feet exterior
The EPA RRP Rule applies when disturbing more than 6 square feet of painted surface per room interior or 20 square feet exterior in pre-1978 housing and child-occupied facilities. This triggers lead-safe work practice requirements.
Why This Is the Correct Answer
The EPA RRP Rule establishes specific thresholds for when lead-safe work practices must be followed in pre-1978 buildings. The rule requires certified renovators and lead-safe work practices when disturbing more than 6 square feet of painted surface per room for interior work, or more than 20 square feet for exterior work. These thresholds were established because smaller amounts of paint disturbance are considered to pose lower risk for lead exposure, while larger areas require formal lead-safe procedures.
Why the Other Options Are Wrong
Option A: 2 square feet interior, 10 square feet exterior
These thresholds are too low and do not match the EPA RRP Rule requirements. The actual thresholds are higher at 6 square feet interior and 20 square feet exterior.
Option C: 10 square feet interior, 25 square feet exterior
These thresholds are too high and would allow more paint disturbance than the EPA permits without lead-safe work practices. The actual thresholds are lower at 6 square feet interior and 20 square feet exterior.
Option D: Any amount of paint disturbance
This is incorrect because the EPA RRP Rule does establish specific square footage thresholds before requirements are triggered. Small amounts of paint disturbance below the thresholds do not require certified renovators or formal lead-safe work practices.
Memory Technique
Use '6 and 20' - think 'six rooms inside, twenty outside' to remember 6 sq ft interior and 20 sq ft exterior thresholds
