EPA is not sufficiently regulating wastewater from plastic production plants, a new report says. The Environmental Integrity Project, a nonprofit founded by two former EPA attorneys, found that many petrochemical plants do not have any limits in their permits for discharging nitrogen and phosphorous into waterways. Of the 70 plants studied, none had limits on total nitrogen in their pollution control permits. One had a limit on phosphorous pollution.
