On September 11, 2001, the Deutsche Bank building at 130 Liberty Street was damaged when debris from the World Trade Center broke windows and cut a 15 story gash in the building’s north façade. As part of the post 9/11 building deconstruction project, the Lower Manhattan Development Corporation (LMDC) contracted with TRC to conduct air quality monitoring in the vicinity of the property during building abatement and deconstruction. The extensive Ambient Air Monitoring network surrounding the Deutsche Bank building was composed of 8-12 stations located on site and at locations neighboring the site. The network monitors continuously for particulate and particulate associated contaminants associated with World Trade Center (WTC) dust.​
