Defining the Problem
Poor outdoor air quality leads to increases in illness and death. People with underlying respiratory disease, including asthma or cardiovascular disease, are particularly at risk due to poor air quality. One in 11 New Yorkers (1.3 million adults and 475,000 children) were estimated to have asthma in 2008; asthma-related hospitalization rates in New York are higher than national rates for all age groups. Studies in New York have found that asthma death rates and hospitalization rates are higher among low-income and minority residents than White, higher-income residents.1,2
Cardiovascular disease is the leading cause of death nationally and in New York, with almost 59,000 New Yorkers dying of related illnesses in 2008. 3 The total cost for cardiovascular disease in New York was estimated to be $32.6 billion in 2008, based on extrapolation from national data.4 Mortality rates from heart diseases have been declining nationally and in New York, but are still higher in New York than in the United States as a whole.5 Mortality and hospitalization rates due to heart diseases are highest in Black non-Hispanics among all racial and ethnic groups in New York.6
Extensive evidence shows that both ozone and fine particulate matter (particles that are less than 2.5 microns in diameter) exposures are associated with increased respiratory and cardiovascular illnesses and deaths. Some evidence also shows that ongoing long-term exposure to these pollutants is also associated with the increasing rates of asthma development.7
The United States Environmental Protection Agency (USEPA) regulates certain outdoor air pollutants under the Federal Clean Air Act. USEPA has designated six air pollutants, i.e., carbon monoxide, lead, nitrogen oxides, ozone, fine particulate matter and sulfur dioxide as criteria pollutants, and established health-based air concentration standards for them, known as the National Ambient Air Quality Standards (NAAQS). Due to the efforts of the federal government and the State agencies that control air releases through regulations and permitting, the air quality in New York has greatly improved over the last 40 years. However, with the adoption of the more stringent 2008 ozone NAAQS and the current NAAQS for fine particulate matter, 11 counties8 are currently designated as non-attainment for ozone, fine particulate matter or both pollutants.
The New York State Department of Environmental Conservation (NYSDEC) develops regulations to control releases of air pollutants and implements Federal regulations that seek to reduce ambient air pollution. NYSDEC also is charged with developing State Implementation Plans (SIP) to set out control strategies to reduce criteria air pollutant concentrations in areas exceeding the NAAQS. A SIP evaluates the current air quality status and projects through model forecasts the effect of control measures needed to reach attainment. Because the SIP is a regional plan and includes specific sources, it may not address potential local-scale impacts from sources, such as residential (i.e., outdoor wood boilers installed prior to 2011) or small commercial or institutional biomass burning boilers.9 Another example of a small source not evaluated in the SIP is fast-food char broilers.10 Additionally, the SIP addresses precursors for ozone formation, but does not evaluate specific releases of toxic air pollutants that individually may be of health concern.
Toxic air pollutants, also known as hazardous air pollutants, are those pollutants known or suspected to cause cancer or other serious health effects, such as reproductive effects, birth defects, or adverse environmental effects. Examples of toxic air pollutants include benzene, which is found in gasoline; perchloroethylene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries. Examples of other listed air toxics include dioxin, asbestos, toluene, and metals, such as cadmium, mercury, chromium, and lead compounds. People exposed to toxic air pollutants at sufficient concentrations and durations may have an increased chance of developing cancer or experiencing other serious health effects. These health effects can include damage to the immune system, as well as neurological, reproductive (e.g., reduced fertility), developmental, respiratory and other health problems. In addition to exposure from breathing air toxics, some toxic air pollutants, such as mercury can deposit onto soils or surface waters, where they are taken up by plants and ingested by animals and are eventually magnified up through the food chain. Like humans, animals may experience health problems if exposed to sufficient quantities of air toxics over time. Although the air quality concentrations in New York for many of the toxic air pollutants has significantly improved in recent decades, for some of the air toxics, the general ambient air concentration is still above levels of concern.
Human activities also have increased the amounts of carbon dioxide (CO2) and other heat-trapping gases, collectively called greenhouse gases (GHGs), in the atmosphere. Current scientific evidence suggests that a warming climate poses a serious threat to New York's environmental resources and public health. Climate change affects air quality, water quality, fisheries, drinking water supplies, wetlands, forests, wildlife and agriculture.11 The largest contributor of GHGs is combustion of fossil fuels, such as coal, oil and natural gas used to produce energy and for transportation. Industries such as petroleum and chemical manufacturing also release GHGs and other hazardous pollutants. GHGs trap heat, thereby contributing to regional climate changes which include warmer average temperatures and more frequent and longer heat waves that increase in the frequency and/or severity of extreme weather events, and increase the risk for dangerous flooding, high winds, and other direct threats to people. These climate changes will likely cause region-wide increases in a variety of health outcomes, such as heat-related illnesses and deaths, food and water-borne diseases, certain vector-borne diseases, and injuries associated with extreme weather events. Climate also has significant influence on air quality. For example, warmer temperatures are expected to accelerate chemical reactions in the atmosphere that lead to ozone and fine particle formation.
Executive Order No. 24 (2009) established the goal of reducing GHG emissions from all sources in New York State to 80 percent below levels emitted in 1990 by the year 2050. New York State is building a portfolio of programs and policies aimed at reducing GHG emissions. State programs use emission controls, technical assistance and financial incentives to ease the transition of electric power generation, buildings, transportation and industrial processes away from fossil fuel combustion and towards clean energy. The health benefits of GHG reduction policies include the following: cleaner air (less ozone formation; fewer pollutants released), the encouragement of land-use planning that reduces private car use and encourages more walking and cycling, and safer transportation through community design that accommodates alternative transportation.
Research also shows that policies intended to reduce GHG emissions will have more health benefits if accompanied by complementary policies that target emissions of harmful co-pollutants from sources. These pollutants are directly harmful to humans and directly impact the health of communities where sources (e.g., industrial facilities, transportation sources) are located.12 Coordination of efforts to reduce GHGs and other harmful air pollutants, especially in low-income and minority communities, can provide an efficient and equitable approach to realize the health benefits anticipated with reductions in both GHGs and other air pollutants.
Goals and Objectives for Action
The Air Quality Focus Area Committee identified the following goals and objectives for action as well as sector level interventions to implement the identified goals and objectives:
Goal #1: Reduce exposure to outdoor air pollutants with a particular focus on burdened communities.
- Objective 1a:
- Reduce the annual number of days with unhealthy air as measured by the Air Quality Index (AQI)>100 to 0.
- (Baseline: New York City annual average days 5 for ozone and 6 for PM; Rest of State annual average days 5 for ozone and 3 for PM (2005 - 2009 DEC monitoring data compared to current NAAQS)*
- Objective 1b:
- Implement policies that target vulnerable groups to reduce exposure to short-term increases in pollutant levels (e.g., policies for schools, day cares, children's camps, assisted-living facilities that reduce or reschedule outdoor activities during air quality advisories).
- Objective 1c:
- Reduce releases of pollutants from stationary sources (e.g., large industrial facilities and small sources, such as gas stations, dry cleaners, outdoor wood boilers, fast food char-broilers) and from mobile sources (e.g., cars, trucks, and lawn, farming and construction equipment) that may contribute significantly to local air pollutant levels.
- Objective 1d:
- Coordinate efforts to reduce emissions of harmful co-pollutants with efforts to reduce GHG or carbon emissions.
