Maine LD 1541 Explained: The First US Packaging EPR Program
Maine's LD 1541 was the first US packaging EPR law on the books. Its stewardship-organization model differs from the PRO model used in California and Oregon. Here is how it actually works.

Why Maine matters
Maine's LD 1541, passed in 2021, was the first US packaging EPR law. Its implementation has run on a different cadence and a different structural model than the PRO-based programs in California, Oregon, and Colorado, which makes it both an outlier and a useful reference point for how packaging EPR can be structured in the US.
For multi-state producers, Maine is a check on assumptions: not every US program will look like California-style PRO membership.
Maine's structural model
Maine's LD 1541 uses a stewardship organization model. Producers fund a stewardship organization (SO) under contract with the state's Department of Environmental Protection (DEP). The SO administers reimbursements to municipalities for the cost of managing covered packaging waste, rather than the SO running collection and processing operations directly.
That structural difference matters because it means Maine's fees are calibrated to municipal reimbursement costs, not to recovery operating costs. The result is a fee structure with somewhat different mechanics than CAA-administered states.
Consult Maine DEP for the current selected stewardship organization and whether multi-state CAA membership covers Maine obligations for the active implementation cycle.
Who is a producer in Maine
Maine's producer test follows the same hierarchy as other US programs:
1. The brand owner with US operations. 2. If no US brand owner, the importer of record. 3. If neither, the distributor or seller first placing goods on the Maine market.
Maine has small-producer exemptions and exemptions for certain low-volume, low-revenue producers; consult Maine DEP's current published rule for thresholds.
What Maine covers
Maine's covered material list includes packaging in all three layers and certain paper products. The sweep is broad and largely consistent with other US programs, with Maine-specific carve-outs for some categories. Reusable transport packaging is generally out of scope.
Producers should treat Maine scope as broadly comparable to Oregon and California for planning purposes, while confirming Maine-specific edge cases against the current DEP guidance before final filings.
How Maine fees work
Maine's fee structure is calibrated to municipal reimbursement costs:
- Per-ton fees by material category that reflect what Maine municipalities are spending to manage that material.
- Eco-modulation rewarding recyclability and PCR content, penalizing design contaminants. The exact modulation curves are Maine-specific.
- Reimbursement-based reconciliation at the end of each cycle.
Because the fee base is municipal reimbursement, fees can shift cycle to cycle as municipal contracts change. Producers should plan for some inter-cycle variability.

Maine's 2026 timeline
Maine's 2026 calendar covers registration, data submission, and the start of fee collection; verify exact day-of-month dates against current Maine DEP and stewardship organization publications. The cycle parallels Oregon's structure: register, report, invoice, reconcile.
Multi-state implications
For producers managing California, Oregon, Colorado, Maryland, Washington, and Minnesota through Circular Action Alliance, Maine is the most likely state to require a separate operational relationship rather than an extension of an existing CAA membership. Plan resourcing accordingly.

How Packgine helps
Packgine maintains Maine's stewardship-organization submission format alongside CAA formats, applies Maine-specific rate sheets and modulation curves to your existing SKU-level dataset, and produces the documentation Maine DEP and the SO expect. One dataset, every US state.
