Lead in Paint

Generator/Owner responsible for lead paint chips “cradle to grave”.

Most states require contractor to be licensed by the state in lead removal.

Always contact your Environmental Department, different states have different rules.

Some states require “chain of custody” forms for test samples.

Two governmental agencies with lead requirements: EPA – Environmental

OSHA – Worker Safety

EPA

Generator – Any person, by site, whose act or process produces hazardous waste identified or listed in 40 CFR Part 261 or whoseact first causes a hazardous waste to become subject to regulation.

Sampling of debris the responsibility of the generator. 40 CFR Part 262.11

TCLP – Toxicity Characteristics Leaching Procedures, if waste tested has a leachable lead concentration of greater than 5 ppm it is considered hazardous under the RCRA Act.( Resource Conservation and Recovery Act )

One 55 gallon drum = approximately 200 kg, less than 100 kg per month you are considered a conditionally exempt small quantity generator.

Storage times of 180 days or will be considered “operators of a hazardous waste storage facility”.

Lead In Paint

OSHA Definition: any coating containing ANY amount of lead triggers the standard, then the exposure levels determine the level of implementations/worker protection.

OSHA

1993 - Lead Exposure in Construction Standard 29 CFR 1926.62 Worker safety responsibility of the contractor. Must have a written compliance program. Employee training is triggered when employee exposures equal or

exceed the Action Level on any one day. Action Level: 30 micrograms per cubic meter, 8 hour time

weighted average. PEL – Permissible Exposure Limit: 50 micrograms per cubic meter

8 hour TWA. Competent Person –must be able to identify existing and

predictable lead hazards in the work area and have the authorityto take prompt measures to eliminate such problems
