There is no question that environmental justice (EJ) is and has long been one of the key civil rights issues facing this country. While we may not think about the issue, perhaps because the environment is seen as some amorphous, natural entity, environmental quality varies significantly based on location and socioeconomic status.
Decades of research shows that poor communities of color are far more susceptible to the deleterious effects of air, water, and soil pollution (PDF) than other groups. Though the issue continues to loom large, the country has made progress over the last two decades.The EPA has an Environmental Justice division, an offshoot of Executive Order 12898, which President Clinton signed 20 years ago this February. All 50 states and the District of Columbia now have some sort of EJ legislation or policy on the books.
But despite these successes, much remains to be done. A new study from researchers at the University of Minnesota in PLOS One shows clearly that racial disparities in air quality remain a serious issue (PDF) for public and environmental health in the US.
The authors compared Census data to national information on exposure to nitrogen dioxide, NO2, one of six criteria air pollutants as set by the EPA. Based on the analysis, average NO2 concentrations were 14.5 parts per billion (ppb) for nonwhites, compared to just 9.9ppb for whites. Accordingly, nonwhites were exposed to 38% higher levels of NO2. Exposure also broke down along income levels.
The authors note that these disparities, particularly the major gap along racial lines, likely leads to major public health impacts. They estimate that, if nonwhites had the same rate of NO2 exposure as whites, it would lead an annual decrease of roughly 7,000 ischemic heart disease deaths. To put that in perspective, 3.2 million adults would have to give up smoking to get this same outcome.
Air pollution and race in Northeast Ohio
As you might expect, there is a significant racial disparity in NO2 exposure within the Cleveland metro area. Based on the authors’ data, nonwhites in Cleveland are exposed to 2.3ppb more NO2 than whites on an annual basis. This constitutes the 17th largest gross disparity in the country. Much of the work on urban air pollution focuses on pollutants from stationary sources, particularly coal-fired power plants. But, if you actually break down the data in low-income, minority communities, pollution from transportation emerges as a major issue. In a 2009 report from the Pacific Institute (PDF), residents of Richmond, a low-income community in Northern California, identified freight transport as one of the leading environmental threats to their well-being.
Unlike other pollutants like CO2, SO2, or mercury, the EPA says that 57% of NO2 pollution derives from mobile sources (i.e. automobiles). That number is even higher for Ohio (65%) and Cuyahoga County (77%). NO2 has been linked to asthma, decreased lung function, low birth weight, and elevated risks of both cardiovascular and respiratory mortality.
Unfortunately, NO2 pollution represents a legacy of our country’s highly flawed history of transportation policy, which cut low-income and minority neighborhoods in half and facilitated White flight into the outlying suburbs. Due to such misguided investments, the CDC estimates that 11.3 million Americans live within 150 meters of a major freeway; 47% of these individuals are persons of color.
How does the Opportunity Corridor fit into this?
It is in this toxic environment that ODOT and its allies are planning to drop the Opportunity Corridor, a 3-mile, $330 million highway in the middle of overwhelmingly low-income communities of color. I’ve already discussed some of the social and environmental challenges facing the neighborhoods in the path of the project. These neighborhoods have asthma rates nearly double the national average (PDF), and infant mortality rates have been as high as 69 deaths per 1,000 live births. That number is above the rates for Bangladesh, Burma, Haiti, Pakistan, and Rwanda. Many of these critical health issues are closely linked to transportation.
Air quality in Northeast Ohio
While air pollution data are not available below the county level, examining Cuyahoga County’s numbers paints a clear picture. Cuyahoga County ranks among the dirtiest 10% of counties in the entire country for cancer and non-cancer health risks stemming from hazardous air pollutants (HAPs). It also ranks in the worst 10% of all counties in Ohio, a state where people of color are 1.5 times more likely to contract cancer from HAPs and 3.3 times more likely to live near facilities that emit criteria air pollutants.
As the maps below demonstrate, the neighborhoods where the Opportunity Corridor would run bear an immense share of this burden. Children living in these areas have face dangerously high levels of blood lead contamination; this is a toxic legacy of decrepit housing, for sure, but also of a decades-long campaign to keep tetraethyllead in gasoline, despite ample evidence of its harm. (Neil deGrasse Tyson discussed this issue in great detail on Cosmos last week.) Lead is known to reduce cognitive function and cause behavioral issues in children, including aggression and hyperactivity.
Transportation also represents an important source of fine particulate matter, particularly from heavy trucks/freight, which rely on diesel fuel. While mobile sources only account for 5.2% of PM 2.5 nationally, that portion increases to 12.3% in Ohio and 27.5% in Cuyahoga County; one can only assume it is even higher than this total within these neighborhoods.
We know that PM 2.5 is a leading cause of respiratory and cardiovascular mortality; it is also a dangerous carcinogen. A 2012 study found that reducing levels of particulate pollution in the US by 1 µg/m3 would prevent 34,000 premature deaths annually. In Cuyahoga County, which saw 12,809 deaths from PM 2.5 in 2009, such reductions would prevent 91 premature deaths, more than anywhere else in the state.
Lastly, we know that NO2 is essential for the development of ground level ozone, another dangerous urban air pollutant. Cuyahoga County has consistently remained in nonattainment of EPA ozone standards; from 2006-2008, the County averaged 0.081ppm of ozone, one of the highest marks in the country. The American Lung Association gives the county and the city of Cleveland a solid F for ozone pollution.
All told, the burden of disease in these areas is substantial. Some areas along the proposed highway lose more than 500 years of potential life per 1,000 residents, easily the highest toll in the region. Given the potential of the Opportunity Corridor to exacerbate air pollution in the area, it’s hard to see how the project could avoid being a serious environmental justice issue that calls for appropriate planning and mitigation. Surely, ODOT is on top of this issue?
Environmental justice in ODOT’s planning
Not quite. Inexplicably (though not really, when you think about it), ODOT’s draft environmental impact statement (DEIS) gave short shrift to air pollution (PDF). In the DEIS, ODOT states that the project “does not present concern for air quality,” as it is unlikely to significantly increase carbon monoxide or PM 2.5 emissions. The agency does note that mobile source air toxins (MSATs) will likely increase in certain parts of the project area, but it then dismisses this concern within the same breath. And ODOT completely punts on ozone, stating that the issue is NOACA’s responsibility.
The report’s environmental justice is similarly insufficient. While it does acknowledge that “the project was found to have a disproportionately high and adverse effect to low-income and minority populations,” it claims to address the issue by implementing a “voluntary residential relocation program” (read: forcibly relocating 74 families and 44 businesses for a pittance), throwing some money at a rec center, and building a few noise walls.
But again, in typical ODOT Orwellian fashion, it also states that the project will simultaneously benefit these low-income communities of color by, among other things, improving “access to the Interstate system” and increasing “pedestrian and bicycle access, connectivity and safety.” Apparently enhancing freeway access in an area where most households don’t own automobiles is essential for local non-drivers and great for pedestrians.
EPA criticisms of the Opportunity Corridor
The report includes little, if anything, in the way of plans to mitigate potential increases in air pollution due to additional vehicular traffic or to tackle the severe underlying health issues residents face. Unsurprisingly, EPA Region 5 has criticized the DEIS, saying it contains insufficient information on environmental concerns. The letter pointedly reminds ODOT that the Opportunity Corridor runs through areas that are in nonattainment for ozone and PM 2.5, barely meet four other air pollution standards, and have a series of major environmental justice issues. Simply mentioning these issues in passing so the department can check off another box isn’t going to fly with a project of this import.
I know I’ve said before that Northeast Ohio’s transportation policies are stuck in the 1960s. The Opportunity Corridor is an unfortunate reminder of this fact and of that terrible era of “urban renewal.” Residents of the so-called “Forgotten Triangle” – God I hate that moniker – have a fractious history with the state government, one that has, understandably, left them suspicious of ODOT’s motives.
Public meetings about the project have become contentious, and locals have raised a number of valid criticisms of the project. Yet, the wheel of “progress” inevitably rolls forward once again.
If ODOT ever hopes to garner public buy-in for the Opportunity Corridor, it needs to do more than meet the minimum possible standards. Failing to even mention criteria air pollutants like NO2 and SO2 and claiming that a massive highway project will enhance pedestrian safety isn’t good enough any more. The agency and the project’s supporters can and must do more than the bare minimum. Otherwise, the Opportunity Corridor risks becoming yet another one of Northeast Ohio’s environmental justice disasters.
