PROJECT SUMMARY

TETERBORO AIRPORT AIR QUALITY STUDY

Introduction

Teterboro Airport (TEB) is located on an 827-acre property in Teterboro and Moonachie, New Jersey. As the oldest operating airport hi the New York/New Jersey metropolitan area, TEB has grown into one of the busiest General Aviation airports in the U.S., with over 200,000 arrivals and departures per year. Because of community concerns regarding potential impacts of the airport operations on local ah" quality, the New Jersey Department of Environmental Protection (NJDEP) and ENVIRON International Corporation (ENVIRON) are conducting a year-long air monitoring study of Teterboro Airport. This will be the first long-term study of air quality in the vicinity of an airport ever performed.

Previous Work

In 2001, ENVIRON conducted a screening-level evaluation of potential air quality impacts associated with operations of the Teterboro Airport, which included a screening-level air sampling and analysis study (conducted over a 48-hour period during June 27-29, 2001) ("Screening Study"). The overall results of the Screening Study indicate that airport operations might be affecting ambient air quality in the immediate vicinity. Some of the specific findings of the Screening Study include the following:

  • Concentrations of fuel-related compounds such as benzene, toluene, ethylbenzene, xylene, 1,3-butadiene, and trimethylbenzene were measured in air near Teterboro Airport that were higher than annual average levels that have been reported in Camden and Elizabeth, New Jersey by NJDEP. In contrast, concentrations of non-fuel related air toxics such as carbon tetrachloride, chloromethane, and methylene chloride were similar in magnitude at the three sites. The Screening Study recognized that the sampling results represented a single point in time and thus may not reflect long-term conditions.
  • Concentrations of a number of air toxics were elevated downwind from the airport, compared to background levels measured upwind from the airport. These chemicals include benzene, toluene, ethylbenzene, xylene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene, all of which are fuel related compounds.

At locations in predominantly downwind directions relative to the airport, a greater number of air toxics were detected at higher concentrations downwind from the airport than upwind of the airport.

The major limitation of the Screening Study is that its results represent a single point in time, and thus may not reflect long-term conditions. However, based on the results of the Screening Study, a more extensive study was recommended.

Current Study

The general goals of the Detailed Study are:

  • To assess long-term ambient concentrations of selected air toxics in the immediate vicinity of the airport; and
  • To determine whether contributions from airport operations can be discerned from the contributions of other background sources.

To meet these objectives, the focus of this study is on the compounds known to be emitted by mobile sources (e.g., cars, trucks, and aircraft), with particular attention being placed on those compounds associated with aircraft operations (e.g., takeoff, landing, refueling, idling, and maintenance). The study will involve a combination of real-time monitoring and discrete sampling equipment, which will be used to quantify the following:

  • Gaseous Compounds -Continuous, path-integrated gas measurements of benzene, etfaylbenzene, toluene, xylenes, formaldehyde, nitrogen oxides, and other compounds will be collected using a CEREX UV Sentry Open Path Air Monitoring System.
  • Volatile Organic Compounds (VOCs) and Carbonyls - VOC samples will be collected in six-liter stainless steel SUMMA® canisters. Carbonyl (e.g., formaldehyde, acetaldehyde) samples will be collected on a coated cartridges. These samples will be collected simultaneously using an ATEC Model 2200 Toxic Air Sampler.
  • Fine Particulate Matter (PM2.5) - Continuous PM2.5 measurements will be collected using a Met One E-BAM mass monitor, a portable, real-time beta attenuation monitor suitable for automated and continuous sampling and reporting of PM2.5 concentrations,
  • Black Carbon (BQ - Continuous BC measurements will be collected using a Magee Scientific Model AE- 16 aethelometer. The aethelometer will allow real-time measurement of optically-absorbing BC aerosol particles, which are characteristic of diesel and jet exhaust.
  • Traffic Data - A Wavetronix Smart Sensor radar device will be used to collect traffic data, on Route 46 and Moonachie Avenue. The Smart Sensor is a non-intrusive traffic monitoring system that will record number of vehicles, speed, occupancy, and perform a limited classification of the vehicles (classified as small, medium, and large vehicle).
  • Meteorology - A RM Young Wind Monitor- AQ wind sensor will be used to collect wind direction and wind speed data.

Data will be collected throughout the calendar year 2006 from four monitoring stations located around the airport fenceline near each of the runways.
