The Clean Water Act’s Nurdle-Shaped Gap: Using the CWA to Address Primary Microplastic Pollution

Michigan Journal of Environmental & Administrative Law 2024 2 citations

AI summary Read the abstract

This legal analysis examines how the Clean Water Act could be used to address pollution from nurdles, the small plastic pellets used as raw material in plastics manufacturing that escape into waterways by the trillions each year. The author argues that current regulations leave a significant gap in addressing primary microplastic pollution despite the known dangers to wildlife and humans. The study proposes regulatory strategies under existing environmental law to hold nurdle dischargers accountable.

The term “nurdles” may sound like a silly made-up word lifted from the pages of a children’s book, but unfortunately nurdles are all-too real, with trillions of these microplastics ending up in our oceans each year. Nurdles spill into the environment at every step along their supply chain, allowing them to end up in fish and on our plates. Despite the known danger nurdles pose to both wildlife and humans, they are virtually unregulated. In the absence of regulation by the Environmental Protection Agency (EPA), some states and their citizens have begun trying to wrangle rogue nurdles, and hold nurdle dischargers accountable, on their own. Unfortunately, due to the sheer volume of nurdles escaping into the environment and their mobility once out there, even the most successful local efforts are unable to make a dent in the nurdle problem. However, the Clean Water Act (CWA) already provides the tools needed to address nurdle pollution at the federal level — it just needs to be used in the right way. This Note offers two such ways the CWA can be utilized in the fight against nurdle pollution. To curb everyday spills caused by improper handling at plastics facilities, the EPA should promulgate a zero nurdle discharge standard for relevant industries. To ensure proper nurdle cleanup in the wake of major shipping accidents, in which millions of nurdles spill directly into a waterway all at once, the EPA should consider classifying nurdles as a hazardous substance under CWA Section 311. As the plastics industry prepares to ramp up North American production, and research increasingly shows the hazards of nurdle ingestion, it is imperative that we address the gaps in our regulatory system that thus far have allowed nurdle pollution to go unchecked.

Past, present, and possible future policies on plastic use in the United States, particularly microplastics and nanoplastics: A review

AI summary Read the abstract

This review analyzed existing U.S. federal and state laws that could be used to regulate microplastics and nanoplastics, including the Clean Water Act and Toxic Substances Control Act. The study found that while multiple statutes exist that could address plastic pollution, none have been specifically invoked for micro- and nanoplastic waste, and current FDA thresholds for acceptable plastic ingestion are far below estimated actual daily exposure levels.

Researchers surveyed pre-production plastic pellet (nurdle) pollution in a New Zealand estuary, finding these raw plastic manufacturing feedstocks contaminating an important wildlife habitat. Nurdle spills are a significant but often overlooked source of microplastic contamination in coastal ecosystems.

Prevention and control strategies for non-regulated industrial microplastic spills

AI summary Read the abstract

Researchers reviewed prevention and control strategies for industrial microplastic spills — particularly plastic pellet losses from the plastics processing industry — which are not yet comprehensively regulated despite representing a large and identifiable source of primary microplastic pollution. They examined existing and proposed regulatory frameworks, including a European Commission proposal for pellet handling regulations, and evaluated detection and response measures for unregulated industrial spill events.
