NYC 9/11 Public Portal Document
the HVAC system, if applicable, should be inspected. If dust is present, recommend filter replacement. Indoor air sampling will be conducted for: asbestos (NIOSH 7400 and, if an action level is exceeded, NIOSH 7402, PCMe), respirable crystalline silica (NIOSH 7500), and inhalable, thoracic, and respirable airborne particulate matter for fraction analyses of silica, gypsum, mica, etc. (lOM sampler). Indoor floor dust sampling will be conducted for asbestos (via TEM as the detection limit for PLM is 1%); for silica, gypsum, mica (XRD); and for magnesium (EPA Method#). Floor dust sampling will be conducted using EPA’s Environmental Response Team (ERT) SOP for household dust collection. Any deviations from the SOP in actual field collection will be documented by the sampling team. 2. Exterior Air and settled dust sampling should occur in a grid pattern in residential areas. Ambient air sampling will be conducted at breathing height for: asbestos (NIOSH 7400 and, if an action level is exceeded, NIOSH 7402, PCMe ), respirable silica (NIOSH 7500), and inhalable, thoracic, and respirable airborne particulate matter for fraction analyses of silica, gypsum, mica, etc. (lOM sampler). In addition, 24-hour real-time TSP, PM 10 and PM 2.5 sampling will be conducted-again at breathing zone height. Settled dust samples will be collected and analyzed for asbestos (via TEM as the detection limit for PLM is 1%); for silica, gypsum, mica, and calcite (XRD); and for magnesium (EPA Method
