NYC DEP Variance Application:

In order to execute the particular requirements of this unique project, specific relief from RCNY Title 15 is requested as follows:

We request relief from 1-125(i): Isolation Barriers. It is the intent of the project to seal all windows and communicating openings to the outside of the building from the outside with two layers of 6-mil poly and plywood barriers. The intent of this action is to create a sealed structure that will allow decontamination activities within the building while reducing the possibility of migration of dust to the outside of the structure.

We request relief from 1-81(j); 1-81(m); 1-91; 1-102(b);1-41(c); 1-41(d);1-112(d); and 1-112(e): Attachment FR- Procedures for use of Foam or Similar Viscous Liquid in Removal of Asbestos Containing Roofing (ACRM) in New York City. Roof membrane, flashing, and roof tar remain on the roof of the building.

We request relief from 1-83(b)2: Attachment DW — Waste Decontamination in • Worker Decon. This request is made to provide for the efficient decontamination of the workspace at the entry to the building so that an interior decon can be built. Attachment DW is requested because the erection of full worker and waste decons outisde the building will result in blockage of the sidewalk. This request is only for the initial entry- cleaning phase.

We request relief from 1-41(c);1-41(d);1-81(m);1-82(a);1-83(a);1-91; Attachment EC — Abatement of Exterior ACM Caulking Materials. ACM window caulk exists on the window frames of the building.
