NYC 9/11 Public Portal Document

Based on the 2000 Consensus, there are approximately 11; residences in the 10 block radius of the WTC. NYC DEP has estimated there are 2500 commercial buildings south of Canal St. A subset of these buildings have not been abated at this time. Cleaning of these buildings followed by confirmatory sampling may need to be conducted. In order to determine an appropriate protocol for dust abatement, EPA will abate the interior of one apartment building completely. This will be followed by the cleanup and sampling of the interior of a subset of buildings according to the procedures established above. Background buildings will be identified (e.g., above 59* st) and sampled to determine appropriate benchmarks for chemicals of concern for buildings affected by the WTC collapse.

Residential - Establish a Protocol for Dust Abatement of Test Apartment Building

Crews will complete cleanup of a small apartment building (e.g. 24 apartments). New York City Office of Emergency Management is identifying a representative building. The process will occur in 3 stages: setup, cleanup, and tear down. Setup involves videotaping, moving furniture and establishing negative pressure using blowers and vizqueen. Cleanup includes HEPA vacuuming carpeting, furniture, drapes and wet-moping hard surfaces such as wood floors and counter tops. Tear down includes post cleanup sampling and analysis, and removal of cleaning equipment and setup materials. Replacement costs for furniture, drapery and other porous materials are not included here, this is viewed as a last resort.

Test Apartment Building Costs; Set Up, Cleanup, and Testing of Each Apartment - $12,000 - $16,000

Total Costs (24 apartments) - $384,000

OSHA’s Procedures for Oversight of Cleanup Contractors for Commercial and Residential Buildings

Create Contract Language for Agencies to use that specifically addresses employee health issues related to building cleaning such as administrative controls, employee PPE, employee training, cleaning practices, and disposal procedures. Create Pre-qualification Contract Bid Specifications to ensure that properly qualified contractors are hired. These specifications will include effective safety and health programs, competency of staff and OSHA citation history.

Implement Oversight Contract Adherence (OCA) -- OSHA will retain a environmental abatement contractor to ensure compliance with the contract performance specifications and to ensure employees are properly protected and trained. This contractor will also collect oversight data and organize it into a database.
