Important Facts for Unhealthful Days from Carbon Monoxide, PM-10, Lead, Sulfur Dioxide, and Nitrogen Dioxide

Definition

Unhealthful days are determined by the National Ambient Air Quality Standards, which include standards for carbon monoxide, coarse particulate matter (PM-10), lead, sulfur dioxide, and nitrogen dioxide

Numerator

Total number of unhealthful days throughout the state, as determined by the National Ambient Air Quality Standards, attributable to carbon monoxide, coarse particulate matter (PM-10), lead, sulfur dioxide, and nitrogen dioxide

Denominator

Why Is This Important?

The air in New Jersey is affected by many naturally occurring and man-made pollutants. Air quality in the state varies significantly depending on location, time and weather conditions. High or prolonged levels of air pollution are associated with increases in morbidity and mortality from respiratory illnesses, such as asthma and lung cancer. The Clean Air Act requires that National Ambient Air Quality Standards (NAAQS) be set for carbon monoxide, PM-10, lead, sulfur dioxide, nitrogen dioxide, and ozone.

Other Objectives

Healthy New Jersey 2020 Objective EH-1: Reduce the number of unhealthful days throughout the state, as determined by the National Ambient Air Quality Standards, attributable to carbon monoxide, coarse particulate matter (PM-10), lead, sulfur dioxide and nitrogen dioxide.

How Are We Doing?

During 1999-2014, there were no air quality exceedances in New Jersey for carbon monoxide, coarse particulate matter (PM-10), or lead. There were no exceedances during 1999-2009 for nitrogen dioxide (NO2) or sulfur dioxide (SO2). In 2010, the health standards for nitrogen dioxide and sulfur dioxide were revised downward creating stricter air quality standards for New Jersey. Using the new standards, the NO2 standard was exceeded twice in 2010 and twice in 2014. The revised SO2 standard was exceeded 4 times in 2010, 27 times in 2011, once in 2012, 4 times in 2013, and 6 times in 2014. All SO2 exceedances were measured at a single air monitoring station located in Warren County, NJ. NJDEP has determined that a coal-burning power plant located directly across the Delaware River from New Jersey, is the source of the SO2 air pollution exceedances measured in Warren County. Because of these exceedances of the health standard, New Jersey has successfully petitioned the USEPA to take action to reduce emissions from the plant. NJDEP has negotiated an enforceable agreement to shut down the 2 coal units at this power plant as of 2014. The NO2 exceedances occurred at two air monitoring sites. One monitoring site is located in Bayonne and the other site is at Exit 13 of the New Jersey Turnpike in Elizabeth. NO2 is a combustion product emitted by both stationary and mobile sources, especially those burning diesel fuel.

What Is Being Done?

The New Jersey Department of Environmental Protection (NJDEP) continues to work to reduce pollution from both mobile sources (eg, cars, trucks, buses, airplanes, trains), and stationary sources (eg, factories, power plants, gas stations, other industrial activities). NJDEP will continue to monitor and identify air pollutants and their sources, using continuous air monitoring stations located throughout New Jersey.
