Hurricane Sandy Response
Hurricane Sandy Response Efforts
Response timeline | January 30, 2013:
The U.S. Army Corps of Engineers, at the request of New York City, is using two air curtain incinerators at Floyd Bennett Field in Brooklyn, NY to burn vegetative debris, largely from downed trees, gathered in the cleanup from Hurricane Sandy. An air curtain incinerator is a self-contained system that reduces wood debris to ash. It is equipped with air blowers that circulate the air to improve combustion and minimize emissions of fine particles.
The U.S. Environmental Protection Agency has eight fine particle monitors operating around the perimeter of Floyd Bennett Field to monitor for potential impacts of the air curtain devices. An EPA On-Scene Coordinator is on-site while the burning takes place to monitor what is being burned and air quality at the field.
Levels of fine particles are measured by the monitors and averaged over a 24-hour period. Results from the monitors are compared to an established 24-hour health-based standard. That standard is 35 micrograms per cubic meter of air (�g/m3). If the 24-hour standard is exceeded, the EPA will notify the Army Corps and New York City. Monitoring began on December 28.
Air Monitoring for Air Curtain Incinerator
Between December 28, 2012 and January 8, 2013, results from operating monitors for the air curtain device burn at Floyd Bennett Field showed that the 24 hour standard had not been violated. Since December 28, results from operating monitors showed that the 24 hour standard has not been violated, except for January 9, 13, 28 and 29. On January 29, five of the EPA�s air monitors measured levels that exceeded the 24 hour standard. On all of the four days, overall weather conditions in NYC and most of the northeast and New York City resulted in an inversion in the air, which reduced the atmosphere's ability to mix and dilute pollution. For a more detailed discussion of each day, please see:
In order to reduce the impacts of the air curtain devices at Floyd Bennett Field on air quality, steps were taken to limit the operation of the devices to reduce particle emissions.
The EPA has an established Air Quality Index reports daily air quality across the country. The index indicates how clean or polluted the air in a particular area is and what associated health effec ts might be a concern. For more information about the Air Quality Index, visit http://airnow.gov/.
