-- Ambient air quality standards The Federal Clean Air Act establishes two types of national ambient air quality standards for six principal pollutants: ozone, particulates, sulfur dioxide, lead and nitrogen. Primary standards set limits to protect public health, including the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards set limits to protect public welfare, including protection against decreased visibility, damage to animals, crops, vegetation, and buildings. The Bureau of Air Quality Monitoring in the state DEP maintains Ambient Air Monitoring Sites throughout the state to measure pollutant concentrations and assess population exposure. According to the DEP's most recent report, in 2022 New Jersey had nine days on which there was an exceedance of either the ozone or fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS). Ozone pollution in New Jersey tends to be a warm-season problem, since it is formed in the presence of sunlight from other pollutants such as volatile organic compounds and nitrogen oxides. During the 2022 summer ozone season, seven days were “Unhealthy for Sensitive Groups” and one day was “Unhealthy” for ozone. And although particulate matter levels in New Jersey are usually good to moderate, in July a wildfire in the Pine Barrens caused the PM2.5 concentration at the Brigantine air monitoring station to reach the “Unhealthy” level. The entire state of New Jersey is currently classified as a non-attainment area for ozone by the EPA, along with much of its surrounding region in eastern Pennsylvania and southern New York State. Ground-level ozone is a pollutant, commonly visible as smog, posing a significant health risk, especially for children with asthma, which also damages crops, trees and other vegetation. It is formed when oxides of nitrogen and volatile organic compounds react in the presence of sunlight. In addition to ozone, urban areas in the state also exceed standards for fine particulate matter, which is produced both by natural causes like volcanos as well as the burning of fossil fuels in vehicles, power plants and various industrial processes. Particulates have been tied to various bronchial and cardiovascular problems, including cancer and heart disease. State officials have attributed much of New Jersey's high level of particulates to out-of-state sources to its west, especially from coal-burning power plants, with significant amounts carried into the state by the prevailing westerly winds. Within the state, the largest source of emissions is from mobile sources, primarily cars, trucks and other motor vehicles. In 2013, the state conducted slightly over 2.1 million initial emissions inspections of motor vehicles, with 10.8% of vehicles failing the initial inspection and 2.7% failing to pass subsequent inspections. Other pollutants are produced from unidentified sources, secondary atmospheric formation or natural emission sources. New Jersey has met the attainment levels for sulfur dioxide (except for a portion of Warren County), lead, and nitrogen dioxide. * Division of Air Quality, New Jersey Department of Environmental Protection * 2022 New Jersey Air Quality Report, New Jersey Department of Environmental Protection * Attainment Areas Status, Bureau of Air Quality Planning, New Jersey Department of Environmental Protection * AirNow New Jersey, US Environmental Protection Agency |

-- Air Toxics In addition to pollutants regulated through the National Ambient Air Quality Standard program, federal and state programs limit emissions for designated air toxics known as Hazardous Air Pollutants believed to have adverse health impacts including lung irritation, birth defects and cancer. These emissions are categorized as coming from point sources (e.g. stationary facilities like power plants, refineries, factories, incineration); area or nonpoint sources (small sources of pollution which when added together account for a significant portion of emissions, such as gas stations, auto body shops, pesticide application, dry cleaners, and consumer product use); and mobile sources (on-road cars, trucks, buses and motorcycles and non-road aircraft, trains, lawnmowers, boats, and construction and farm vehicles and equipment). Mobile sources are the state's largest source of emissions. In 2013, the state conducted slightly over 2.1 million initial emissions inspections of motor vehicles, with 10.8% of vehicles failing the initial inspection and 2.7% failing to pass subsequent inspections. Other pollutants are produced from unidentified sources, secondary atmospheric formation or natural emission sources. * Air Toxics in New Jersey, New Jersey Department of Environmental Protection * America's Dirtiest Power Plants Drive Global Warming, Pollution; Environment New Jersey -- Regional Greenhouse Gas Initiative
In 2011, the Christie Administration withdrew from the Regional Greenhouse Gas Initiative (RGGI), a consortium to reduce carbon dioxide emissions from power plants across ten Northeast and mid-Atlantic states from Maine to Maryland. The action, which the Governor claimed was due to the RGGI being ineffective and that its implementation would likely lead to increased utility rates, sparked litigation instituted by environmental groups which delayed, but did not halt, the withdrawal. Subsequent bills passed by the legislature to have the state re-join the program were vetoed by Governor Christie. The state rejoined the RGGI after Governor Murphy took office. In November 2021, he signed an executive order establishing a goal to reduce carbon emissions in New Jersey by 50% by 2030. In addition, the governor announced another $33 million for transportation electrification projects from the RGGI. * Regional Greenhouse Gas Initiative |
