NYC 9/11 Public Portal Document
COPC document, which was adopted as a secondary clearance value for this project, is 1 jxg/m’. Although the value chosen for this project was 1 gg/m’, tire analytical detection limit available for analyzing crystalline silica in indoor air samples is higher than this value, therefore a result that is below the detection limit is considered to be protective of public health. Four out of eleven samples (36%) were above the detection limit of 11 ranging from 17.2 to 22.1 These values are also above the secondary clearance value.
Although these values are above the clearance value, they are similar to concentrations detected in a background study conducted by USEPA. In the USEPA background study, there was a frequency of detection of 25%, with a range of 4 to 259 jug/m’. Further, the values from the background study without the maximum value of259 provide a range of 4 to 28 This indicates that the range of values observed in 114 Liberty Street are similar to those observed in the background study. Based on this, it has been determined that the crystalline silica results are similar to background values and therefore additional cleaning is not necessary.
