Zero Bids for Stewardship Organization, Including CAA: Maine EPR Faces Timeline Delay

Maine was one of the first states to pass a packaging Extended Producer Responsibility (EPR) law, back in 2021. Five years later, it's finally moving from paper into practice. If you sell packaged products into Maine, here's where things stand as of August 20, 2026, and what to do about it before the rules are fully locked in.

At a glance

• Law passed: 2021
• RFP published: June 15, 2026
• Current stage: DEP Step 4, "Contracting with an SO"
• CAA bidding: No (announced it will not respond to the RFP)
• Producer registration/invoicing: expected late 2026 (unconfirmed)

The short version

If you're a producer selling into Maine, here's what this means for you:

• Maine's program has cleared the rulemaking stage; the legal framework is largely settled
• The organization that will actually run day-to-day compliance (collecting fees, processing registrations, reimbursing municipalities) hasn't been hired yet
• Because that piece is still unresolved, several key dates you'd normally plan around are still moving targets

What is Maine's Stewardship Organization (SO)?

Most states in this space use the term "Producer Responsibility Organization." Maine doesn't. Maine calls its operator a Stewardship Organization, or SO; same idea, different name, and worth knowing so you're not searching for the wrong term in the state’s Department of Environmental Protection (DEP)’s materials.

The SO will run the operational side of the program: producer registration, reporting, invoicing, the stewardship fund, municipal cost studies, and reimbursements. Maine's DEP keeps the regulatory oversight role.

As of now, an SO has not been selected or announced. Circular Action Alliance (CAA), the country's largest Producer Responsibility Organization, isn't in the running. More on that below. Don't treat any prospective SO's forms, templates, or fee estimates as final until a contract is signed.

CAA just passed on Maine’s RFP

Here's the update that changes the picture: CAA has announced it will not bid on Maine's SO request for proposals. That's a reversal from where things stood earlier because CAA had previously signaled it intended to respond.

CAA's stated reasoning is worth reading carefully, because it's narrower than "we're pulling out of Maine." According to CAA:

• This is about the RFP's scope, not about Maine's EPR goals, and not a withdrawal from the state
• The RFP as written isn't aligned with CAA's operating practices, systems, and data stewardship standards
• It doesn't match the consistent producer experience CAA delivers across the states where it already operates (California, Colorado, Maryland, Minnesota, Oregon, and Washington)
• CAA remains open to a future Maine RFP if the scope lines up better with how it operates

<noquote>If you were assuming CAA, already familiar to many producers from other states, would simply extend its footprint into Maine, that assumption no longer holds. Worth watching, but not worth acting on yet.

When does Maine's packaging EPR law take effect?

Almost every practical deadline in Maine's law counts down from a single moment: the effective date of the DEP–SO contract. Once that's signed:

• Producers must register within 90 days of the SO opening registration
• Producer payments are due within 180 days of the contract taking effect
• Applications for Alternative Collection Programs can open on that same effective date
• The ban on selling products in noncompliant packaging kicks in one year after that date

None of these clocks have started yet, because the contract hasn't been signed.

How the timeline has shifted

CAA's original Maine timeline penciled in an SO contract by spring 2026 and producer registration by May 2026. That didn't happen; the RFP itself wasn't published until mid-June, and now CAA, the bidder many assumed was the likely pick, isn't submitting a proposal at all. 

DEP's current, more conservative outlook: producer registration and invoicing near the end of 2026, with municipal reimbursements possibly following near the end of 2027. Both are planning assumptions, not commitments — DEP and whoever is eventually selected will set a firmer schedule once a contract is in place.

Once the program is fully running, the recurring annual cycle looks like this: producer reports by May 31, invoices by July 1, producer payments by September 1, municipal reimbursements by October 1. That's the steady-state rhythm separate from the one-time start-up schedule still being worked out.

What are the current EPR requirements for Maine?

• Even with the SO still unnamed, a good amount of the underlying framework is already settled law.
• The producer hierarchy, core exemptions, and reporting structure are established in statute and in Chapter 428 (Maine's implementing rule, adopted in December 2024 and amended in February 2026).
• Producers will report packaging using the material types defined in Appendix A (See Ch 428: Stewardship Program for Packaging), added to the rule this past February.
• Low-volume producers, those supplying more than 1 but fewer than 15 tons of packaging annually, get simplified reporting and a capped flat fee: $500 per ton, up to $7,500 a year.

If a producer can't pin down Maine-specific tonnage, DEP's current guidance allows reporting national tonnage instead, with Maine's share estimated using population data.

What hasn't Maine decided yet about its EPR program?

• Who the SO will be: CAA is confirmed out of the running, and no other bidder has been named
• The contract's effective date, and the revised start-up calendar that follows from it
• Actual fee amounts. Chapter 428 sets the framework, but real numbers depend on producer data, SO operating costs, and a statewide recycling needs assessment that hasn't happened yet
• Detailed producer guidance on classification, registration, and estimation methods

What to do now, even without deadlines in place

Waiting for DEP's final invoicing instructions before you start preparing is the expensive way to do this. Right now, brands selling into Maine should:

1. Identify the Maine producer: the specific legal entity responsible for each product and sales channel
2. Map packaging to Appendix A: brands, products, components, and weights, sorted into Maine's official material types
3. Document your estimation method and keep the underlying data. DEP's guidance explicitly addresses how tonnage gets estimated, and unsubstantiated claims about packaging characteristics can carry measurable downside
4. Check exemptions carefully: revenue, tonnage, closeout-business, nonprofit, and food exemptions all exist in statute, but eligibility should be checked against the actual text, not a summary (including this one)
5. Build cross-functional ownership now: legal, tax, sustainability, packaging, sales, and finance all have a stake here, and untangling that later is harder than setting it up early

For budgeting, build a range of scenarios rather than one number. Separate out expected SO administration costs, material-management fees, any recyclability-based incentive adjustments, and potential offsets from Alternative Collection Programs. The actual fee schedule isn't fixed yet, but the categories it will draw from already are.

The bottom line

Maine's legal architecture is largely built. The machinery that runs it is not… yet. That gap is also an opportunity: companies that get their producer status, packaging data, and estimation methods in order now won't be scrambling when DEP names the SO and the clock starts running.

FAQs

Is Maine's packaging EPR program operational?

No. Maine's packaging Extended Producer Responsibility (EPR) law passed in 2021 and has cleared the rulemaking stage, but the program is not yet operational. The organization that will run day-to-day compliance, called the Stewardship Organization (SO), has not been selected. As of August 2026, Maine's Department of Environmental Protection (DEP) lists the program at Step 4 of its process: "Contracting with an SO."

What is a Stewardship Organization (SO)?

A Stewardship Organization, or SO, is Maine's term for the entity that will administer its packaging EPR program day-to-day: producer registration, reporting, invoicing, the stewardship fund, municipal cost studies, and reimbursements. Most other states use the term "Producer Responsibility Organization" (PRO) for the equivalent role. Maine's Department of Environmental Protection (DEP) retains regulatory oversight; the SO handles operations.

Did Circular Action Alliance (CAA) win Maine's SO contract?

No. Circular Action Alliance (CAA), the country's largest Producer Responsibility Organization, and the organization many assumed would take on Maine's program, announced it will not submit a bid in response to Maine's SO request for proposals (RFP), published June 15, 2026. This reverses CAA's earlier signal that it intended to respond.

Why did CAA decide not to bid on Maine's RFP?

CAA says the decision is about this specific RFP's scope, not about Maine's EPR goals, and not a withdrawal from the state. According to CAA, the RFP as written isn't aligned with its operating practices, systems, and data stewardship standards, or with the consistent producer experience it delivers across the states where it already operates (California, Colorado, Maryland, Minnesota, Oregon, and Washington). CAA says it remains open to a future Maine RFP if the scope better matches how it operates.

Has any organization been selected to run Maine's program?

No. As of August 2026, no SO has been named. Whether other organizations submitted proposals in response to Maine's RFP has not been made public, and neither Maine DEP nor any other party has named a frontrunner.

What deadlines apply to producers under Maine's EPR law?

Almost every practical deadline counts down from one event: the effective date of the contract between Maine DEP and the selected SO. Once that contract is signed:

• Producers must register within 90 days of the SO opening registration
• Producer payments are due within 180 days of the contract's effective date
• Applications for Alternative Collection Programs may open on that same effective date
• The ban on selling products in noncompliant packaging begins one year after that date

None of these deadlines have started, because the DEP–SO contract has not been signed.

When will Maine's packaging EPR program actually start?

There is no confirmed start date. Maine DEP's current planning assumption is producer registration and invoicing beginning near the end of 2026, with municipal reimbursements possibly following near the end of 2027. Both figures are planning estimates, not commitments, and are subject to change once an SO is selected and a contract signed.

What is already settled under Maine's packaging EPR law, even without an SO?

Several elements of the program are established in statute and in Chapter 428 (Maine's implementing rule) regardless of who the SO turns out to be:

• The producer hierarchy, core exemptions, and reporting structure
• Packaging material classifications, defined in Appendix A (added to Chapter 428 in February 2026)
• A simplified reporting track and capped flat fee ($500 per ton, up to $7,500 annually) for low-volume producers supplying between 1 and 15 tons of packaging per year
• An allowance for producers to report national packaging tonnage, with Maine's share estimated using population data, if Maine-specific tonnage can't be determined

What still hasn't been decided about Maine's EPR program?

• Who the SO will be (CAA is confirmed out; no other bidder has been named)
• The DEP–SO contract's effective date, and the revised start-up calendar that follows from it
• Actual fee amounts (the statutory framework exists, but real numbers depend on producer data, SO operating costs, and a statewide recycling needs assessment that hasn't been completed)
• Detailed producer guidance on classification, registration, and estimation methods, which DEP has said is coming in summer 2026

What should a brand selling into Maine do right now, before the SO is selected?

Five things, regardless of the final timeline:

1. Identify the specific legal entity that is the "producer" for each product and sales channel
2. Map packaging, including brands, products, components, and weights, to Maine's Appendix A material types
3. Document the estimation method used for packaging tonnage, and retain the underlying data
4. Check exemption eligibility (revenue, tonnage, closeout-business, nonprofit, and food exemptions all exist in statute) against the actual statutory text
5. Establish cross-functional ownership now, across legal, tax, sustainability, packaging, sales, and finance

What is the recurring annual reporting cycle once Maine's program is operational?

Once running, Maine DEP's standing annual cycle is: producer reports due by May 31, invoices issued by July 1, producer payments due by September 1, and municipal reimbursements by October 1. This recurring cycle is separate from the one-time start-up schedule still being finalized.
