The table lists target guideline for the parameter that ATC evaluated during this investigation. Meeting the listed value does not assure that acceptable indoor air quality will be achieved at all times.
TARGET GUIDELINE FOR INDOOR AIR QUALITY PARAMETER EVALUATED ii t FL HmMO ____ ii _________________ ■ _______ y 65 micrograms per cubic Respirable meter of air (pg/mQ 24-hour USEPA \PAAQS Particulates (PM^j) average 40 micrograms per cubic USEPA recommendation for meter of air (ug/m ') 24-hour children and sensitive average individuals USEPA = United States Environmental Protection Agency NPAAQS = National Primary Ambient-Air Quality Standard
RESULTS
ATC collected one (1) 24-hour gravimetric sample in the Main Lobby. The analytical laboratory report is provided in the attachment.
The 24-hour average concentration ofPM2 5 was 14.6 ug/m’ which is below both the EPA NPAAQS for PM, 5 of 65 ug/m’ and the EPA recommended level of 40 ug/m’.
It is our pleasure to provide these indoor air consultative services to the New York City Department of Education. If you have any questions about this report, please call (212) 353-8280, extension 212.
