Read twice and referred to the Committee on Environment and Public Works. (text: CR S1583)

What it does
This bill would require the EPA Administrator to create specific pollution limits for pre-production plastic pellets — the small raw plastic beads used to manufacture plastic products. It would direct the EPA to issue formal regulations (known as "promulgating limitations") governing how these pellets can be discharged or released into the environment. The bill is currently in committee and its full regulatory details, compliance timelines, and enforcement mechanisms are not specified in the available text.
Who benefits
Communities near plastic manufacturing and shipping facilities, particularly those along waterways where pellet spills are most common. Commercial and recreational fishers whose catch and waters may be affected by pellet contamination. Wildlife conservation groups and marine ecosystems that would see reduced plastic pollution. Municipal water utilities that treat water for pellet contamination. Beachfront and coastal tourism industries. Consumers who may benefit from reduced microplastic exposure in seafood and drinking water.
Who is hurt
Plastic resin manufacturers and compounders who would face new compliance costs and operational requirements. Plastic pellet transporters and logistics companies subject to new handling or spill-prevention rules. Downstream plastic product manufacturers who may face supply disruptions or cost increases during a compliance transition. Small and mid-sized plastics businesses with fewer resources to absorb regulatory costs. States and localities that currently regulate pellet pollution independently and may face preemption or conflicting standards.
Supporters argue
Supporters argue that billions of pre-production plastic pellets — known as "nurdles" — enter U.S. waterways each year through industrial spills and runoff, and that no comprehensive federal standard currently exists to limit this discharge. They contend that nurdles are a leading source of microplastic contamination in marine environments, with studies finding them in seafood, drinking water, and wildlife, and that a uniform federal standard would close a regulatory gap that patchwork state rules have failed to address consistently.
Opponents argue
Opponents argue that directing the EPA to promulgate new categorical limitations imposes significant compliance costs on the domestic plastics industry without clear evidence that federal regulation would be more effective than existing state-level programs or voluntary industry initiatives like Operation Clean Sweep. They contend that under the major questions doctrine established in West Virginia v. EPA (2022) and the end of Chevron deference under Loper Bright (2024), any broad EPA rulemaking under this mandate would face heightened judicial scrutiny, potentially making the regulations costly to implement and legally vulnerable.
Constitutional context
The bill would direct EPA rulemaking under the Clean Water Act, which is grounded in the Commerce Clause (Art. I, §8, cl. 3). Post-Loper Bright (2024), courts will independently review whether EPA's specific regulatory choices fall within the authority Congress clearly granted, rather than deferring to the agency's interpretation. If EPA's resulting rules are broad in scope, they could also face major questions doctrine challenges under West Virginia v. EPA (2022).
Checks and balances
The executive branch (EPA) gains new rulemaking authority; Congress retains oversight through the legislative process and appropriations; federal courts check EPA's authority under the major questions doctrine and independent statutory review post-Loper Bright.
Historical precedent
The Clean Water Act's existing effluent limitation guidelines for industrial categories provide the closest regulatory model, though no federal rule has previously targeted pre-production plastic pellets specifically as a regulated pollutant category.
