Maine PFAS in Products — LD 1503 (Most Comprehensive U.S. Law)

By the Opora Editorial Team

When Maine Governor Janet Mills signed LD 1503 — formally An Act to Stop Perfluoroalkyl and Polyfluoroalkyl Substances Pollution — on July 9, 2021, the state did something no other U.S. legislature had attempted: it declared that, as a legal default, no product containing intentionally added PFAS may be sold in Maine unless a state agency affirmatively finds that the use is currently unavoidable. Every other PFAS law in the country starts from a list of banned categories and exempts the rest. Maine's law inverts that logic entirely. Codified at 38 M.R.S. § 1614 and significantly amended by Public Law 2023, Chapter 630 (LD 1537, effective August 9, 2024), the statute represents the most aggressive statutory posture toward PFAS in any U.S. jurisdiction — and the commercial cleaning industry sits squarely in its crosshairs, with cleaning products prohibited under the 2026 wave and every other category scheduled for elimination by 2032.

The Ban-by-Default Architecture: A National Bellwether

Most PFAS laws resemble building codes: they enumerate prohibited items and leave everything else permissible. Maine's LD 1503 operates like a controlled-substances list: the default posture is prohibition, and the burden of proving necessity falls on the manufacturer. Under 38 M.R.S. § 1614(1)(B-1), a Currently Unavoidable Use (CUU) designation means "a use of PFAS that the [Maine Department of Environmental Protection] has determined by rule to be essential for health, safety, or the functioning of society and for which alternatives are not reasonably available." That standard is deliberately narrow: it does not encompass products for which fluorinated alternatives are merely cheaper or better-performing — it requires that the product serve a function that society cannot perform without PFAS chemistry.

Only the Board of Environmental Protection (BEP) holds authority to approve or deny CUU proposals, through technical rulemaking under the Maine Administrative Procedures Act (MAPA) with public hearing and comment. Approved CUU designations have a five-year shelf life under the 2024 amendments; manufacturers must reapply, and the BEP may decline renewal if alternatives have become commercially available. The amended Chapter 90 rule took effect October 7, 2025, and is the operative regulatory framework for the January 1, 2026 prohibition wave.

Phase-by-Phase Sales Prohibition Schedule (38 M.R.S. § 1614)

The 2023 carpet-and-rug prohibition and fabric-treatment prohibition took effect over two years ago. Encapsulation technicians and carpet-protection specialists whose core service model relies on fluorotelomer-based fiber protectants must reformulate entirely for Maine accounts — any continued sale or distribution in those categories is an active violation of 38 M.R.S. § 1614.

Cleaning Products: Scope for Janitorial Operators

Maine's Chapter 90 rule defines "cleaning product" broadly: "a finished product used primarily for domestic, commercial or institutional cleaning purposes, including, but not limited to, an air care product, an automotive maintenance product, a general cleaning product and a polish or floor maintenance product." A "general cleaning product" encompasses soaps, detergents, and chemically formulated products labeled for cleaning, disinfecting, or caring for surfaces — floors, furniture, countertops, and appliances. The definition expressly includes "cleaning products used for domestic, commercial or institutional cleaning purposes" — there is no commercial-use exemption analogous to Minnesota's industrial-manufacturing carve-out.

This means every SKU in a janitorial distribution catalog — floor strippers and finishes, carpet pre-sprays, bathroom disinfectants, glass cleaners, degreasers — must be verified PFAS-free before sale in Maine after January 1, 2026. For distributors operating across New England, the Maine cleaning-products ban is the earliest trigger date among neighboring states and functions as a de facto compliance floor for the region.

Currently Unavoidable Use Petitions: Process and Fee Structure

Manufacturers who believe their PFAS-containing product qualifies for a CUU designation must use Maine DEP's online CUU proposal form. For the January 1, 2026 prohibition wave, the proposal deadline was June 1, 2025. For future waves (2029, 2032, 2040), proposals may be submitted no earlier than 60 months and no later than 18 months before the applicable ban date — DEP's review and Board rulemaking can take up to 18 months. Each proposal must address a specific combination of product category and industrial sector; collective industry filings are permitted. Manufacturers with approved CUU determinations must submit a PFAS Notification Form and pay the associated fee to continue lawful sales; approved proposals appear in the Maine Environmental License System (MELS) Explorer, filterable by "Permit Program – PFAS." Confidential Business Information claims are managed under 38 M.R.S. § 1310-B and must be asserted at submission.

Enforcement Powers and Penalty Structure

Maine DEP has acknowledged in Chapter 90 that its initial enforcement posture focuses on "encouraging voluntary compliance." However, the agency's statutory authority under 38 M.R.S. §§ 347-A through 349 is substantial. Civil penalties may reach $10,000 per day per violation for manufacturers selling prohibited products; criminal penalties — requiring a willfulness finding — can reach $25,000 per day per violation under 38 M.R.S. § 349. Enforcement actions available to MDEP include: consent agreements; referral to the Attorney General for civil or criminal prosecution; enforcement hearings; and civil action following a notice of violation. Retailers share exposure: a retailer is in violation of the sales prohibition if they continue to offer a product for sale after receiving notice from the manufacturer that the item is prohibited. A manufacturer who issues such a notice — voluntarily or at DEP's direction — is required to also provide DEP with a list of all notified parties.

Exemptions from the Prohibitions

The 2024 amendments (LD 1537) established an explicit exemption list. Entirely exempt from Maine's PFAS sales prohibitions (no ban, no CUU petition needed):

• Products for which federal law governs PFAS content and preempts state authority;
• Packaging (as defined under Title 32, section 1732) used solely as packaging;
• Used products or used product components (products installed, operated, or utilized by at least one prior owner);
• Firefighting or fire-suppressing foam;
• Medical devices, drugs, and FDA-regulated products;
• DOT, FAA, NASA, DOD, or DHS-mandated products;
• Motor vehicles, watercraft, aircraft;
• Semiconductors and semiconductor manufacturing equipment;
• Non-consumer laboratory equipment or electronics.

A small-manufacturer exemption covers the reporting obligation for businesses with 100 or fewer employees (raised from 25 by LD 1537), but this does not exempt small manufacturers from the underlying sales prohibitions. Maine also has no exemption for industrial-process cleaning products — unlike Minnesota, a floor cleaning product used in a semiconductor fab must have a CUU designation or be PFAS-free.

Compliance Steps and Bid-Template Language for Maine Accounts

1. Confirm 2023 compliance is complete: The carpet, rug, and fabric-treatment bans have been in effect since January 1, 2023. Any continued sale or use of PFAS-treated carpeting, entrance matting, or fluoropolymer protectants on Maine accounts is an active violation of 38 M.R.S. § 1614.
2. Complete 2026 product audit by Q4 2025: Cross-reference every cleaning-product and textile SKU against the 2026 prohibition schedule. All floor-care chemistry, surface cleaners, and air-care products must be confirmed PFAS-free or covered by a CUU determination before January 1, 2026.
3. Obtain CAS-level supplier attestations: Request written confirmation from manufacturers disclosing PFAS content by Chemical Abstracts Service (CAS) registry number, per the original LD 1503 notification framework.
4. Monitor MELS Explorer for CUU updates: Track Maine DEP's PFAS in Products page for current approved CUU designations, particularly for specialty chemistries.
5. Establish 5-year records retention: Retain all CUU notifications, supplier attestations, and compliance correspondence for at least five years, matching the 5-year CUU renewal cycle.

Bid-template language for Maine accounts: "All cleaning products, floor-care products, textile goods, and fabric treatments supplied under this agreement comply with Maine's PFAS in Products Program under 38 M.R.S. § 1614 and Maine DEP Chapter 90 rule. Supplier certifies that no product supplied contains intentionally added PFAS, or that a Currently Unavoidable Use designation has been issued by the Maine Board of Environmental Protection and a current PFAS Notification Form is on file with Maine DEP. Supplier shall provide written documentation on request and shall notify Buyer promptly if any product becomes subject to a new Maine PFAS sales prohibition."
