Environmental Justice for Overburdened Communities: A View from New Jersey

 Last year, the New Jersey state legislature passed a landmark environmental justice bill that requires the state’s Department of Environmental Protection to identify overburdened communities in the state and to evaluate whether facilities seeking operating permits pose a   disproportionate, cumulative environmental impact on these communities. Facilities located in the same census tract as overburdened communities are subject to this requirement and include facilities that are major sources of air pollution (as defined under the Clean Air Act); resource recovery facilities or incinerators; sludge processing facilities, combustors, or incinerators; sewage treatment plants with capacity over 50 million gallons per day; and certain kinds of landfills.
This important piece of legislation was signed into law by the governor making New Jersey the first state to require a mandatory denial of a permit for new facilities and to impose conditions on renewal and expansion permits for existing facilities based on environmental justice (EJ) concerns alone. A new permit will be denied for facilities “where an [EJ] analysis determines a facility will have a disproportionately negative impact on overburdened communities.”
An overburdened community is defined in this bill as any census block group that fulfills at least one of the following criteria:

  • At least 35% of households qualify as low-income
  • At least 40% of residents identify as minority or as members of a tribal community
  • At least 40% of households have limited English proficiency

A low-income household is one that is at or below twice the poverty threshold (determined annually by the US Census Bureau)
A household with limited English proficiency is one where no adult speaks English “very well,” according to the US Census Bureau.
The bill requires that a company that wants a permit for a new facility, an expansion of a facility, or a permit renewal for an existing facility and if that facility is located partially or completely in an overburdened community, then the company must do the following three things:

  1. Write an environmental justice impact statement that evaluates the unavoidable potential environmental and health impacts associated with the facility and  the environmental and health impacts already affecting the overburdened community.
  1. Provide the environmental justice impact statement to government entities and the Community.
  1. Hold a public hearing no sooner than 60 days after providing the environmental justice impact statement:
    • The public hearing must be publicized in at least two newspapers that serve the community (including one non-English language newspaper).
    • The notice of the public hearing must include: description of the proposed facility, summary of the impact statement, date/time/location of the hearing, address at which community members can submit written comments.
    • The state Department of Environmental Protection will post the impact statement and the information about the public hearing on its website.

At the hearing the company “shall provide clear, accurate and complete information.”

Asbestos At The Mill And In The Black Neighborhood Around It

An estimated 2,200 tons of asbestos are buried in a mound behind the five-acre former Carolina Asbestos Company in downtown Davidson. It’s the leftover byproduct of the company that made shingles, automotive brake linings and other asbestos products from 1930 to about 1970.
While the factory was up and running, sometimes asbestos floated in the air into surrounding yards. Over the years, it also ran onto neighborhood streets and into a stream downhill from the factory. And some was moved around town intentionally — carried from the mill to fill in people’s yards and driveways. Longtime resident Marvin Brandon knows that firsthand.
“They could go over and get the asbestos, put it in the trunk of the car, bring it home, spread it out on their driveways and crush it up, just break it up, or drive over it to break it up. Because I remember my dad doing it several times,” Brandon said.
Asbestos also may have been used to help fill in what’s now the town-owned Roosevelt Wilson Park, off Griffith Street. Sections of the park these days are surrounded by orange fencing and warning signs while the town awaits an EPA cleanup.

The Rachel Carson Amendment

Our colleague and friend Lou Zeller at the Blue Ridge Environmental League (BREDL) shared an article he wrote a few years back about the great pioneer Rachel Carson who wrote in her epic 1962 classic Silent Spring that “If the Bill of Rights contains no guarantee that a citizen shall be secure against lethal poisons distributed either by private individuals or by public officials, it is surely only because our forefathers despite their considerable wisdom and foresight, could conceive of no such problem.”
Lou continued. “The public outcry created by Silent Spring led to a ban on DDT from agricultural use in 1972. However, today the industrial use of poisonous substances continues almost unabated, based on regulatory risk assessments and legally acceptable death rates. For example, retail shops are still permitted to dry-clean cloths with perchloroethylene, a carcinogenic solvent, even though non-toxic alternatives are available. Household hand cleaners laced with toxic Triclosan contaminate wastewater and sewage sludge deposited on farm fields as fertilizer. Nuclear power plants routinely spew radioactive Tritium into the air and water. And chemical giant Monsanto sells the weed-killer Roundup to farmers and homeowners—components of which are carcinogenic and known to damage the liver, kidney, brain and lungs. The list goes on.
“How can it be that after the passage of two generations we have let this continue?  Worse, a new natural gas extraction industry—cracking underground rock with high-pressure chemicals and water—exempts itself from the few environmental, public health and safety laws still on the books. It is indeed a strange blight creeping over the land.
“The Fifth Amendment to the US Constitution states, ‘No person shall…be deprived of life, liberty, or property, without due process of law.’  The Fourteenth Amendment adds that the States may not, ‘deny to any person within its jurisdiction the equal protection of the laws.’ Rachel Carson’s Fable for Tomorrow painted a grim picture, but it was meant to prompt action.  In part, she succeeded.  But it remains to us to ensure that the next forty years complete the changes necessary so our legacy to future generations is not a silent spring.  Either the fundamental principles established under the Constitution mean what they say, or Rachel Carson’s admonition should become the 28th Amendment to the Constitution.”
I think Lou is onto something. What do you think?

Residential Segregation and Disproportionate Exposure to Airborne Carcinogens

Researchers at Washington University in St. Louis published a paper late last year that found carcinogens present in the air of the St. Louis metropolitan area to be highly concentrated in Black and poor neighborhoods. They found that approximately 14% of the census tracks in the city had elevated cancer risk due to exposure to toxic chemicals in the air and that these air toxic hots spots were independently associated with neighborhoods with high levels of poverty and unemployment, and low levels of education. Census tracks with the highest levels of both racial isolation of Blacks and economic isolation of poverty were more likely to be located in air toxic hot spots than those with low combined racial and economic isolation.
This paper is important because the authors used an innovative geospatial approach developed by other researchers to identify spatial patterns of residential segregation in their study area. This approach captures the degree of segregation at the neighborhood level and identifies patterns of isolation of different metrics, which in this study was black isolation and poverty isolation. This approach differs from tradition methods that looked at the percentage of blacks or poverty in a neighborhood.
The authors used these two segregation measures – Black isolation and poverty isolation – to identify neighborhoods segregated by race and income in the St. Louis metropolitan area and evaluated the risks of exposure to carcinogens in the air in these areas. The cancer risk data came from the Environmental Protection Agency’s National Air Toxics Assessment and the census track sociodemographic data came from the American Community Survey. All spatial analyses were conducted using Arc GIS software.
These researchers found that census track levels of poverty, undereducation and unemployment were associated with toxic hot spots, while factors such as per capita income and median household income were inversely associated with toxic hot spots. These findings support other studies that identified disparities in exposures to ambient air emissions of toxic chemicals and that raised questions about whether residential segregation leads to differential exposure to air pollutants.
While the authors discuss a number of possible pathways connecting segregation and health, the relationship between segregation and exposure to air toxics is unclear. They discuss various factors that result in segregation leading to the “cycle of segregation” that includes neighborhoods with low social capital, few community resources and low property values which tends to attract more low income and minority residents and exposures to unhealthy air toxics.
The authors concluded that this study provides strong evidence of the unequal distribution of carcinogenic air toxics in the St Louis metropolitan area and that residential segregation leads to differential exposure to chemicals in the air that cause cancer.

Toxic Tuesday: Creosote

Creosote is a large mixture of chemicals that is used as a wood preservative in the United States, as well as for roofing, aluminum smelting, and road paving. Houston’s Fifth Ward has been pinpointed as a Cancer Cluster: an area that has a “greater than expected number of cancer cases,” largely due to the community’s exposure to creosote from the Union Pacific railroad site in Houston’s 5th Ward.
Creosote is released into soil and water systems and may take many years to break down. Due to groundwater contamination, creosote can make its way into drinking water systems, putting entire communities at risk for exposure. Creosote may cause irritation of the respiratory tract and can lead to stomach pains and burning of the throat and mouth. The International Agency for Research on Cancer and the EPA have determined that creosote is likely a carcinogen, meaning that exposure to the chemical can likely cause cancer.
CHEJ has been working with the Texas Health and Environment Alliance (THEA) to help the communities of Houston’s 5th Ward further understand the extent of the contamination and what different health investigations can do to propel THEA’s goals of raising awareness of their exposure to creosote. CHEJ and THEA have been hosting informational Zoom town halls about Houston’s 5th Ward Cancer Cluster. You can learn more about Houston’s Cancer Cluster by watching Fault Lines’ mini documentary or by visiting THEA’s Facebook page to learn and listen in on their past and future town hall meetings or learn how to get involved.

A Pandemic of Pollution

The death toll due to Covid-19 passed the 90,000 mark in the United States this week. This is a truly staggering if not sobering number that raises many questions about how we as a nation respond to this incredible loss of life. These are not just numbers, but people – someone’s mother, father, brother, sister, grandfather, grandmother, uncle, aunt, friend, lover, child… The daily news boils this down to statistics. Numbers of new cases and deaths are reported each day before the newscaster moves on to the next story. Are we normalizing this staggering loss of life? Even worse, are we accepting it?
Yet I look at the leadership of this country and I don’t see people who empathize with those who have lost someone to this deadly virus. I don’t see people who are taking steps to minimize the impact of this insidious virus.
There is still much that we don’t know about Covid-19 and its effects on people, but it is becoming quite clear that low income residents and people of color are disproportionately impacted by exposure to the coronavirus. It’s also become clear that underlying health conditions, such as respiratory problems like asthma and COPD; diabetes, high blood pressure, immune diseases like lupus multiple sclerosis make people more vulnerable to covid-19, not just among the elderly, but among people of color and others with these diseases.
Why then is the USEPA doing all that it can to dismantle (repeal or weaken) regulations that protect people’s health. A report released today by the Senate Environment and Public Works Committee describes how specific actions taken by EPA to weaken or repeal air pollution rules and regulations will “harm public health and potentially add to COVID-19 risks.”
The report specifically points to seven rules that were initially designed to remove greenhouse gas, soot, mercury and other pollution from the air that the agency has targeted and proposed or finalized actions since March 1st that “will result in increased air pollution and could cause tens of thousands of premature deaths. EPA has, in short, unleashed a pandemic of pollution in the middle of an actual pandemic, the respiratory effects of which may be amplified by pollution exposure.”
The committee is clear that the agency should reverse its deregulating efforts and strengthened rather than weaken the country’s air pollution laws and regulations, and take steps to address the Covid-19 specific risks posed by air pollution. In the committee’s words:
“EPA should re-focus its enforcement, compliance and monitoring activities in a manner that prioritizes the early detection of high exposure to air pollutants in communities that have both historically experienced such exposures and those at greatest risk of adverse outcomes from COVID-19.”
This and other recommendations made by the Senate Committee offer hope that we will not accept 90,000 deaths and counting as the cost of doing business in the United States. There are steps we can take to reduce and minimize the impacts of Covid-19.

Vulnerability to Pollution and Susceptibility to Covid-19

A new screening tool is now available that identifies populations across the country that are most vulnerable to severe complications following exposure to the coronavirus and development of covid-19. This community vulnerability map which was developed by Jvion, a health care data firm, in collaboration with Microsoft. Jvion uses socioeconomic and environmental factors, such as lack of access to transportation, exposure to pollution, unemployment and mortality rates at the census block level to identify communities vulnerable to severe effects of covid-19.
In an article about his new mapping tool in Grist magazine, Jvion is described as using “machine learning to analyze block-level data from the U.S. Census to identify ‘environmental health hazards’ as one key socioeconomic factor that makes a population more vulnerable  to severe covid-19 outcomes, based on the health effects of polluted air, contaminated water and extreme heat. They also factored in how chronic exposure to outdoor respiratory air pollutants such as fine particulate matter can increase the risk of cancer, respiratory illness and cardiovascular disease – preexisting conditions that make exposure to the novel corona virus more severe and fatal.”
This interactive and searchable map differs from others available on the internet in that it identifies the populations that once infected will likely experience severe outcomes ranging from hospitalization to death.
This vulnerability map can be used together with the USEPA’s EJScreen, an Environmental Justice Screening and Mapping tool. The EJScreen uses 11 environmental and health indicators and standard demographic data to identify communities most susceptible to air quality pollution. The EJ screen specifically includes a cancer risk and respiratory hazard index that is provided as a percentile in the state or nationally.
When the vulnerability mapping tool is matched with the EPA’s EJ Screen, the results are astounding. The relationship between a community’s proximity to industrial facilities and the projected risk of severe covid-19 outcomes is very clear and very strong. The areas of high vulnerability identified on the Community Vulnerability map match well with areas with high pollution from industrial facilities identified by the EJScreen, painting an all too familiar picture of communities suffering disproportionately from multiple and cumulative risks.
The preexisting respiratory and other health conditions that African Americans suffer from living in the shadows of industrial facilities in sacrifice zones across the country contribute significantly to their susceptibility to the lethal effects of covid-19. This reality isn’t an accident, but the result of economic and environmental conditions imposed on people of color over the long history of discrimination in this country.
In spite of these obvious disparities and the growing threat that people of color and African Americans in particular face from covid-19, EPA announced this month that it has stopped enforcing regulations that hold corporate polluters accountable for releasing toxic chemicals into the air we breathe. This is another outrage. Sign our petition to demand that the government reverse this disastrous decision.

Partnership Between University and Community finds Airborne Health Risks from PCBs in New Bedford Harbor Sediment

A unique collaboration between university and community led to an important study evaluating the human health risks posed by airborne polychlorinated biphenyls (PCBs) coming from sediment in the New Bedford Harbor in Massachusetts. Researchers from Boston University found that the harbor, the home of one of the largest PCBs Superfund sites in the country, is the primary source of PCBs in the air around the harbor. They described the harbor as the “largest reported continuous source of airborne PCBs from natural waters in North America.”
The study found that PCB levels in the ambient air were highest closest to the harbor and that changes in thyroid levels are more likely to occur among people who live near the harbor compared to residents who live further away. These researchers focused on the non-cancer risks posed by exposure to PCBs rather than the cancer risks which EPA used to drive its decisions on the cleanup of the harbor which has been ongoing since the 1990s. So far, more than 425,000 cubic yards of PCB-contaminated sediment has been removed from the harbor as of December 2017 according to the EPA. Much of this waste has been placed in a constructed landfill in the harbor. The local group, Hands Across the River, has been fighting to stop the agency from doing this for years.
In response to requests from residents to monitor the ambient outdoor air for PCBs in places where they live, researchers from Boston University partnered with the Toxic Action Center, the University of Iowa and local residents to identify locations and design a monitoring program to meet community needs. In contrast, EPA selected monitoring locations for convenience or where concentrations were expected to be the highest.
The researchers modeled the data they collected and for the first time were able to estimate residential exposures and health risks for residents living around the harbor. They chose the thyroid as a target of PCB toxicity based on strong evidence in human and animal studies in the scientific literature. They compared thyroid changes in residents and PCB levels in the ambient air near and distant from the harbor and were able to show potential health risks associated with proximity to the PCB contaminated Superfund site in the New Bedford Harbor.
EPA’s response to these findings in part was to say that “the measured levels of airborne PCBs have never exceeded EPA’s health-based criteria.” This of course misses the point that this study identified new health risks beyond what the agency had previously considered. EPA’s standard risk procedures do not capture all health risks. Their focus was on cancer risk. This study focused on non-cancer health risks.
It has long been suspected that PCBs in the sediment of rivers and waterways will evaporate to some degree and eventually become airborne, but industry and government have pushed back arguing that PCBs do not substantially volatilize and if they did, their impact would be insignificant. This study puts that argument to rest.
This study is a remarkable example of what scientists and researchers can do together to address community needs. Scientific information is a powerful tool when university expertise and resources are focused on responding to community concerns. In this collaboration, new risks were identified that EPA had not previously considered. More of these collaborations are needed.

How About Some PFAS with your Pizza?

By: Sharon Franklin
pizza
Kristina Marusic, of Environmental Health News reported on October 9, 2019  about the dangerous PFAS chemicals that show up in the bodies of people who eat takeout, fast food, and pizza are often at higher levels than in people who regularly cook at home.  This is according to a new study, which is the first to link certain foods and PFAS exposures in Americans and adds to the mounting evidence that food packaging, (i.e. grease resistant boxes, pizzas and popcorn) is a major source of exposure to the toxics in people.  PFAS (Per- and polyfluoroalkyl substances) refers to a class of more than 5,000 chemicals that are used to make everything from food packaging and cook wear to furniture, carpets and clothing grease-, stain-, and water-repellent.  They’re sometimes called “forever chemicals” because they don’t break down naturally.  These chemicals can accumulate in the body and have been linked to many health issues, including cancer, thyroid disease, low birth weight and decreased fertility.
 
Dr. Laurel Schaider, who co-authored the study PFAS in drinking water (STEEP)  says “We all know eating more fresh foods and more home-cooked meals is good for our health for many reasons,” and “I think our study adds further evidence to support that.  She and her co-authors analyzed data collected between 2003 and 2014 from 10,106 participants in the National Health and Nutrition Examination Survey (NHANES), a program of the Centers for Disease Control and Prevention (CDC) that tracks health and nutritional trends in the United States.  Dr. Schaider also stated that “We found that every 100 calories of food purchased at a grocery store and prepared at home instead of at a restaurant was associated with 0.3 to 0.5 percent lower levels of PFAS in our bodies”.
Dr. Schaider concluded, while eating at home was associated with lower levels of PFAS than eating out overall, eating fast food and pizza were most strongly linked with higher levels of PFAS in people.  “We know we’re exposed to PFAS from many different sources, “but our findings indicate that food consumption is an important pathway of exposure.”  Ultimately, we need better regulations to keep harmful chemicals from getting into our food and products in the first place.”

Changing the Traditional Understanding of How Chemicals Affect Our Health

The way scientists think about how chemicals cause their toxic effects is changing. Recent scientific research tells us that the traditional notion of how chemicals act is being replaced by a better understanding of the actual features of exposures to environmental chemicals. These features include the timing and vulnerability of exposures, exposures to mixtures, effects at low doses and genetic alterations called epigenetics.
Traditional thinking tells us that how much of a chemical you are exposed to (the dose) determines the effect. This principle assumes that chemicals act by overwhelming the body’s defenses at high doses. We’re learning now that this principle is not always accurate and its place in evaluating risks needs to be reconsidered. What we now know is that some chemicals cause their adverse effects at low exposure levels that are not predicted by classic toxicology.
Recent research has shown that environmental chemicals like dioxin or bisphenol A can alter genetic make-up, dramatically in some cases.  These changes are so powerful that they can alter the genetic material in eggs and sperm and pass along new traits in a single generation, essentially by-passing evolution.
It wasn’t too long ago that scientists believed that the DNA in our cells was set for life, that our genes would be passed on from one generation to the next, and that it would take generations to change our genetic makeup. That’s no longer the case.
This new field – called epigenetics – is perhaps the fastest growing field in toxicology and it’s changing the way we think about chemical exposures and the risks they pose. Epigenetics is the study of changes in DNA expression (the process of converting the instructions in DNA into a final product, such as blue eyes or brown hair) that are independent of the DNA sequence itself.
What researchers are learning is that the “packaging” of the DNA is just as important as a person’s genetic make-up in determining a person’s observable traits, such as blue eyes, or their susceptibility to diseases such as adult on-set diabetes, or to the development of lupus.
The environment is a critical factor in the control of these packaging processes. We may be born with our genes, but epigenetics changes occur because of environmental influences during development and throughout life. These influences include chemicals in the food we eat, the air we breathe, the water we drink, and they appear to contribute to the development of cancer and other diseases.
Epigenetics may explain certain scientific mysteries, such as why certain people develop diseases and others don’t, or why the person who smoked for 30 years never developed lung cancer. There is still much to learn, but an early lesson to take away from this emerging science is that we need to rethink our traditional ideas of how chemicals affect our health.
