LEAD-IN-D UST SAMPLING
Lcad-in-dust threshold levels The New York City Health Code, part 173.14 and the Federal Departments of Housing and Urban Development (HUD) and Environmental Protection Agency (EPA) have established acceptable lead-in-dust levels for re-occupancy after a lead abatement has occuned (commonly refeined to as “final clearance” levels). As staled in the Code, final clearance after abatement has taken place is achieved when dust wipe samples indicate lead levels below those listed below:
For Windov/ wells: 400 pg/tf For Windov,'sills: 250 pg/tf For Floors: 40 ug/ft‘
Although the lead-in-dust samples collected at Stuyvesant HS (M477) were not collected in response to lead abatement, the same thresholds are used since no other regulations or standards are applicable to this project.
