The EPA's written comment deadline for the proposed PFAS drinking water rule is now eleven days away. While the public hearing has already taken place, the rulemaking process remains open, giving manufacturers, importers and downstream users one final opportunity to submit technical information that may assist the EPA before it considers a final rule.
For companies producing or selling PFAS-containing consumer products, this period is more than an administrative deadline. It is an opportunity to present evidence regarding commercial feasibility, transition timelines and the practical implications of replacing PFAS chemistry in specific applications. Well-supported comments contribute more effectively to the regulatory record than general statements of support or opposition.
The EPA's current proposal would rescind Maximum Contaminant Levels for four PFAS compounds while maintaining standards for PFOA and PFOS and extending the compliance deadline for those two substances.
Although the proposal focuses on drinking water regulation, companies across multiple sectors have an interest because regulatory decisions can influence customer expectations, product development priorities and future compliance planning.
The remaining eleven days provide sufficient time for organizations with established technical information to prepare a structured submission supported by commercial evidence.
PFAS continue to appear in a variety of specialized consumer and industrial products because of their unique performance characteristics.
Examples include:
Specialty coatings designed for stain, water or chemical resistance.
Outdoor equipment treatments requiring durable weather protection.
Food packaging additives used in selected applications.
Cleaning products formulated for demanding industrial or commercial environments.
Companies supplying these markets may possess valuable operational information that helps regulators understand how proposed requirements could affect manufacturing, product performance and substitution efforts.
Public comments become part of the official rulemaking record. The EPA reviews submitted information before deciding whether to finalize, modify or withdraw elements of a proposed regulation.
For companies with commercial experience using PFAS, useful submissions may include evidence relating to:
The technical feasibility of replacing PFAS in specific applications.
Expected transition timelines for reformulation or product redesign.
Costs associated with developing and qualifying alternative chemistries.
Manufacturing considerations linked to replacing existing formulations.
Product performance differences between current and alternative materials.
Information grounded in operational experience provides context that may assist the agency when evaluating implementation issues.
Not every public comment carries the same analytical value.
Comments supported by measurable information generally provide regulators with more practical insight than broad policy statements alone.
Examples of useful supporting information include:
Estimated costs associated with reformulation.
Production timelines needed for qualification and customer approval.
Testing requirements before commercial introduction.
Supply chain limitations affecting alternative raw materials.
Manufacturing investments required for transition.
Providing quantified information allows the EPA to better evaluate the practical implications of proposed regulatory changes across different sectors.
Companies that intend to participate should focus on presenting factual, organized and application-specific information.
An effective submission often explains:
The product category involved.
The functional role performed by PFAS.
Available alternatives, if any.
Commercial and technical challenges associated with replacement.
Supporting data for estimated costs and implementation schedules.
Organizing comments in this manner helps regulators understand how proposed changes affect real-world manufacturing and product development.
Regulatory comments are often prepared by legal or regulatory affairs departments, but procurement teams can provide important commercial insight.
Procurement professionals frequently understand supplier capabilities, raw material availability, qualification timelines and pricing considerations that influence transition planning.
Working collaboratively across procurement, research and development, regulatory affairs and manufacturing functions can strengthen the quality of submitted information.
This cross-functional approach also prepares organizations for future compliance planning regardless of the EPA's final decision.
Submitting comments represents only one stage of the broader rulemaking process.
After July 20, the EPA must review submitted comments, respond to significant issues and determine the content of any final rule. That review process may continue for months before regulatory decisions become final.
Companies should therefore view the comment deadline as an opportunity to contribute technical evidence while continuing to monitor future developments in the rulemaking process.
With eleven days remaining before the EPA's written comment deadline, companies that manufacture or sell PFAS-containing consumer products still have time to prepare meaningful submissions supported by technical and commercial evidence. Information addressing alternative chemistry, implementation timelines and quantified costs provides greater analytical value than general position statements alone.
For procurement professionals, participation in the comment process also creates an opportunity to contribute practical supply chain knowledge that may strengthen organizational planning and support more informed regulatory decision-making. Companies with a direct commercial stake should use the remaining time to ensure their operational experience becomes part of the official rulemaking record.
