• may be implemented to protect occupants. Of particular concern are air intakes of the school building directly to the east of the project site. These concerns are being addressed cooperatively with the Department of Education.

Health & Safety Plan:

A Certified Industrial Hygienist (CIH) from Airtek has developed a site-specific HASP to be applied to all site decontamination operations. The HASP details requirements for access/egress and requirements for Personal Protective Equipment for workers at the site. The HASP is attached.

Community Monitoring:

Prior to initiation of any decontamination/de-construction operations, a Community Monitoring Program developed by an Airtek CIH will be established and operational. The Program will consist of daily air monitoring at four points on the perimeter of the project site. At each sampling point one daily air sample for metals will be collected, and three daily asbestos air samples will be collected. Metals samples will be collected and analyzed in accordance with NIOSH 7300, asbestos by TEM (AHERA Rules). Community Monitoring will continue until building demolition is complete.

NYC DEP Variance Application:

• In order to execute the particular requirements of this unique project, specific relief from RCNY Title 15 will be requested by the submittal to NYC DEP of an ACP-7 form with an accompanying ACP-8 Request for Variance form for each of the two structures involved in the project. Variances to be requested will be specific to the conditions in each building, and the variance request will also include the use of Attachment DW (Waste decontamination in Personnel Decon) during the initial lobby-cleaning phase. A copy of the variance request for each building is attached.

NYS DOL Notification:

Due the fact that the decontamination will constitute a `Large Project" according to Industrial Code Rule #56, notification of the project will be made to the NYS Department of Labor. A copy of the DOSH-486 form is attached.

USEPA Notification:

Due the fact that the decontamination will constitute a `Large Project" according to EPA AHERA, notification of the project will be made to the USEPA. A copy of the USEPA notification is attached.
