The Yonkers East Station Post Office was the subject of an expansion and renovation project, which increased the available floor space by about 50 percent. As part of the expansion the existing asbestos roofing system, built-up asbestos containing felt and tar with gravel ballast, was disturbed. The construction required the modification of the parapets and it was specified that the existing roof be removed and replaced with non-asbestos containing materials.
GEA Engineering, Inc. provided the design and Asbestos Project Monitoring and air quality monitoring during the project.
When the GEA representative and the Abatement crew arrived at the site on January 15, 1997, the roof adjacent to the north parapet had been removed and the parapet demolished. The roofing material debris was still present on the roof.
A roofing area strip, about 24 feet long, was abated near the Post Masters office and the debris cleaned up along the north parapet. This phase of the project was conducted as a Minor Project under the provisions of 12 NYCRR Part 56-3, In-Plant Operations, and Applicable Variances 83, 90 and 97.The work areas were inspected after removal and cleanup and were found to be acceptable for the laying of the new roof.
