NYC 9/11 Public Portal Document

Scope of Work

ATC Associates, Inc. (ATC) was retained by New York City Board of Education (NYC- BOE) to collect dust wipes to be analyzed for lead content. Dust wipe samples were collected from areas recommended by Parent Association consultant representative Mr Eric Telemaque of EMTEQUE and approved by NYC-BOE and as specified in the sampling protocol for the school. These areas are the following:

• U' floor lobby outside Auditorium • Cafeteria • Auditorium • Two random classrooms • 3"^^ floor hallway • 5"’ floor hallway • y* floor hallway • 9"’ floor hallway

The purpose of the dust wipe sampling is to determine if dust in the school contains lead. ATC will be repeating this sampling every Saturday as per the recommendation of NYC- BOE. This is the sixth consecutive week that dust samples were collected from High School for Economics & Finance (M833) to be analyzed for lead content.

ATC’s representative Mr. Chacko Mathew visited High School for Economics & Finance (M833) located at 100 Trinity Place, New York, NY 10006 on April 6*, 2002. Dust wipes to be analyzed for lead content were collected from the aforementioned areas indicated to ATC by EMTEQUE and as specified by the New York City Board of Education Environmental Health & Safety Unit and in accordance with HUD protocols.

LEAD-IN-DUST SAMPLING

Lead-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 occurred (commonly referred to as “final clearance” levels). As stated in the Code, final clearance after abatement has taken place is achieved when dust wipe samples indicate lead levels below those listed below:

For Windowsills: 250 pg/tf For Floors: 40 pg/tf

Although the lead-in-dust samples collected at High School for Economics & Finance (M833) were not collected in response to lead abatement, the same thresholds are used since no other regulations or standards are applicable to this project.
