The publication provides just a snapshot of the industry's pollution of U.S. waters. The group focused on plants "that make raw or pure plastics, sometimes referred to as resins, pellets, or nurdles, that are eventually turned into plastic products, like plastic bottles," and did not examine oil refineries or facilities that only make the end-use or consumer products.
"Federal regulations on the wastewater from plastics manufacturing plants have not been updated in over 30 years, are grossly outdated, and fail to protect waterways and downstream communities."
The document explains that "many harmful chemicals released by plastics manufacturers are completely unregulated" by the federal agency, including "dioxins, which are known cancer-causing agents that are highly toxic and persist in the environment; and 1,4-dioxane, a likely carcinogen that EPA scientists recently indicated is threatening drinking water sources."
"Nitrogen and phosphorus pollution discharged from plastics and petrochemical plants—which cause algal blooms and fish-killing low-oxygen zones—are also not controlled by EPA's industrial wastewater rules," it continues. "Although state agencies can set limits for these pollutants in individual wastewater discharge permits, practices vary across states and the limits are inadequate and inconsistent."
EIP found that last year, the 70 plants collectively released nearly 10 million pounds of nitrogen and 1.9 million pounds of phosphorus into waterways. The previous year, eight facilities released an estimated 74,285 pounds of 1,4-dioxane, and 10 of the 17 plants manufacturing polyvinyl chloride (PVC) or its ingredients released 1,374 grams of dioxins and dioxin-like compounds.
The watchdog also found that "although absolute numbers are not known," releases of nurdles into waterways "appear to be common," enforcement of existing regulations is "rare," 58 of 70 plants violated the weak limits "by releasing more pollution than allowed at least once from 2021 to 2023," and 28 facilities are operating with outdated water permits.
"In addition to all these problems, petrochemical plants have been recognized by EPA as potential sources of per- and polyfluoroalkyl substances or PFAS, the 'forever chemicals' that persist in waterways and have been linked to increased cancer risk, hormone disruption, reduced ability of the body to fight infections, and reproductive harms, including low birth weight in babies and developmental delays," the publication notes.
U.S. Geological Survey scientists last month published a study on forever chemicals in the journal Science and released an interactive, online map for the Lower 48 states. They estimated that "71 to 95 million people in the conterminous United States potentially rely on groundwater with detectable concentrations of PFAS for their drinking water supplies prior to any treatment."
EIP's new report highlights that "federal regulations on the wastewater from plastics manufacturing plants have not been updated in over 30 years, are grossly outdated, and fail to protect waterways and downstream communities," despite the Clean Water Act's requirement that the EPA "set wastewater discharge limits (called 'effluent limitation guidelines') for harmful pollutants based on the best available technology economically achievable."
"Because treatment technologies improve over time, EPA is supposed to review existing limits every five years and strengthen them when data show treatment options have improved," the document details. "EPA has failed to comply with this mandate, resulting in an excessive amount of potentially dangerous water pollution pouring from plastics manufacturers into America's waterways."
The group's recommendations are to mandate the use of modern wastewater pollution controls, prohibit plastic discharges into waterways, increase accountability at the state and federal level, enhance monitoring requirements in permitting, and improve permit transparency and recordkeeping.
"It is inexcusable that EPA is not following the Clean Water Act and failing to require the multibillion-dollar plastics industry to install modern pollution control systems," EIP executive director Jen Duggan said in a statement. "Plastics plants are poisoning our waters and contaminating our bodies—and EPA needs to do its job and protect our waterways and downstream communities."
Local groups in Lousiana, South Carolina, Texas, and West Virginia also responded to the report with calls for action.
"Decades of unchecked pollution have transformed the Calcasieu River into a dumping ground for toxic chemicals, with little accountability for the companies responsible," said James Hiatt, executive director of the Louisiana-based For a Better Bayou. "It's unacceptable that these plastics plants, profiting from our natural resources, are allowed to continue to release carcinogens like dioxins into our waterways. We need to hold these polluters accountable—and make them clean up the damage they've caused."
Despite such demands for action, environmental advocates have grave concerns about the EPA's future under Trump, including over his pick of Lee Zeldin, a former Republican member of Congress, to head the agency.
During Trump's first term, his administration rolled back over 100 environmental rules. Although Zeldin, as a congressman, was sometimes "willing and even eager to address environmental problems at home on coastal Long Island," as The New York Timesnoted Tuesday, his voting record and fealty to Trump have green groups fearful for the future.
As Common Dreamsreported earlier this week, Sierra Club executive director Ben Jealous declared that choosing a candidate "who opposes efforts to safeguard our clean air and water lays bare Donald Trump's intentions to, once again, sell our health, our communities, our jobs, and our future out to corporate polluters."
