The Health Behind Plastics Cracker Plants

The plastics cracker complex that Royal Dutch Shell is now building in Beaver County has been touted as a jobs creator and an overall benefit to the economy of southwestern Pennsylvania. But this cracker plant, which is the size of almost 300 football fields, has the potential to harm the health of the entire region for years to come. Given that at least three more complexes are being proposed for the tristate area, the risks to public health should not be taken lightly.

Let’s take a closer look at cracker plants and how they can impact your health, as well as general environmental and economic concerns a petrochemical build-out will have.

What a Plastics Cracker Plant Does

A plastics cracker plant is a large industrial complex that heats ethane – a component of natural gas – and “cracks” it into ethylene. Ethylene is used to create plastic nurdles, which are small pellets that form the basic building blocks of most plastic products. These nurdles are shipped to industries all over the world to make items we use in everyday life.

But where does a cracker plant get its ethane? In the case of the Shell cracker plant, the vast majority of the ethane will come from shale gas development right here in southwestern Pennsylvania. Compressed ethane from shale gas wells will be fed through hundreds of miles of pipelines and compressors to the cracker plant. At least 1,000 full-producing fracked wells will be required every year to feed the voracious appetite of each cracker plant.

How Cracker Plants Can Impact Your Health

Just like the network of shale gas wells, compressor stations, and pipelines that feed them, cracker plants release toxic pollutants into the atmosphere. These pollutants include fine particles that you breathe in. They also include volatile organic compounds (VOCs) like benzene, sulfur dioxide, carbon monoxide, and formaldehyde, which can enter your body through your lungs or skin.

Once operational, the Shell cracker plant has been permitted to release more than 30 tons of hazardous air pollutants, 323 tons of fine particles, and 522 tons of VOCs. These numbers make it a major contributor to pollution in our region. As EHP has modeled it, emissions will affect the health of people living five miles or more from the complex.

The dangerous chemicals cracker plants release are associated with a host of serious health issues, including:

  • Increased rates of asthma

  • Lung and respiratory infections

  • Heart problems

  • Fatigue and nausea

  • Poor birth outcomes

  • Neurological issues such as memory impairment

In large enough doses over time, many of these chemicals can cause cancer. A large-scale petrochemical build-out in southwestern Pennsylvania would start to look a lot like a similar area in Louisiana that’s been dubbed “Cancer Alley.” Do we really want an Appalachian Cancer Alley here in our own backyard?

Focus on the Bigger Picture

Our region’s air quality is already among the worst in the nation, and local air pollutants are recently on the rise again after years of declines. The pollutants emitted from the cracker plant will likely cause air quality across the region to worsen even more. Further, the Shell cracker plant is permitted to release more than 2 million tons of CO2 each year. Because it's a significant greenhouse gas, CO2 emissions contribute to climate change. According to Jim Fabisiak at the University of Pittsburgh, these CO2 emissions are the equivalent of emitting as much pollution as 36,000 cars driving 12,000 miles per year – a 25 percent increase in the number of cars driven in Beaver County.

According to a Carnegie Mellon University study, a petrochemical build-out in southwestern Pennsylvania will result in shorter lifespans for thousands of residents in the region. With the planet facing a climate crisis, made worse by significant quantities of methane leaking from shale gas facilities, now is not the time to increase our extraction and processing of fossil fuels, especially for making plastics.

A Better Economic Model

Setting aside the health impacts for a moment and focusing on the economics, the Shell cracker plant is estimated to create about 600 ongoing jobs. But Pennsylvania lawmakers gave Shell a sweetheart deal – a $1.65 billion tax cut over 25 years, the biggest tax break in state history. What this means is that the state is essentially paying Shell about $275,000 for each long-term job it’s creating.

In Pennsylvania, jobs involving renewable energies are already outpacing those in the fossil fuel industry. If this tax money had been invested in bringing more renewable energy jobs into the region, the state would be in a much better economic condition going forward.

What Can You Do?

  • If you live near a cracker plant, you should be aware of the health risks you face and take measures to protect your health and that of your family.

  • If you live in the region generally, you can tell your local and state legislators that you want them to strictly and continuously monitor pollution coming from the plant and make sure limits are not exceeded.

  • If a second cracker plant is proposed nearby, you should consider fighting against it, as health problems can become compounded when additional facilities are added.
