The Department is authorized to require the owner, contractor or an approved agency to provide verification of the project’s compliance. R327.1.1 Requirements.

Painted materials removed from buildings, or portions thereof, constructed prior to 1978 shall not be eligible for reuse or recycling unless tested and verified to be free of lead paint, or tested and tagged in a lasting manner to assure proper handling of lead hazards for all materials transferred off-site. Such tags must indicate possible lead exposure risk and that mandated handling methods must be followed. Tags shall remain in place until materials are sold or processed in compliance with regulations governing lead-based paint promulgated, or as may be promulgated, by DOEE or the federal Environmental Protection Agency, including, but not limited to 40 CFR § 745.85 (7-1-12 edition), and in conformance with all pertinent lead abatement requirements in D.C.
