Third: flexibility stays principled only while those backstops bite, and this case structurally resembles the arrangements where they have not. Collaborative, flexible environmental governance has a sobering record — particularly in nutrient management, where regimes relying on voluntary nonpoint commitments have repeatedly deferred or missed watershed targets while the enforceable point-source obligations held. Great Bay is built on exactly that structure: binding limits on the treatment facilities, voluntary municipally chosen measures for the larger nonpoint share. The relevant literature also locates cultural and relational capture in high-capacity, technically dense, repeat-player settings, which describes this forum precisely. The claim that Great Bay differs is therefore conditional and testable, not established. | |||
Fourth: the distinguishing test is whether learning converts into obligation at a scheduled moment.

The 2026 successor permitting process is that scheduled moment, and it is the test the arrangement was built for. | |||
Because these are claims rather than observations, the conditions that would refute them can be named in advance: the independent legal accountability party exits the settlement; permitting primacy passes to an agency that has previously retreated under pressure; nonpoint reductions remain a small fraction of target through the next cycle; or the successor process re-approves the existing arrangement without converting monitored learning into enforceable watershed obligation. Any of these would indicate that this case belongs with the arrangements it currently claims to differ from. | |||

Great Bay Estuary Nitrogen Governance
| Scale: | subnational |

| System: | complex |

1. Situation Overview
Time orientation: ongoing · Scale: subnational · System: complex · Key stakeholder community: Knowledge · Status: renegotiation
Timeline (6–8 key events): 2006 — The last wastewater discharge permits issued for Great Bay facilities contain no nitrogen requirement.
2008–2009 — Nitrogen becomes the contested variable. A technical advisory process disputes total nitrogen as the driver of estuarine decline, while NHDES drafts preliminary watershed nitrogen loading thresholds. EPA responds supportively in general terms but questions the proposed numeric standard, noting it would require very large nonpoint-source reductions to achieve.
2010–2012 — Conflict institutionalizes. Municipalities form the Great Bay Municipal Coalition in response to the draft thresholds; EPA issues draft permits carrying nitrogen limits; municipalities advance an adaptive-management alternative emphasizing staged investment across point and nonpoint sources. Litigation follows in multiple directions — against the state, and with notice given to EPA — alongside congressional attention to the federal role and the formation of a competing advocacy coalition. Several communities withdraw from the litigation.
2013–2014 — The scientific dispute is routed into peer review. The Environmental Appeals Board denies review of EPA's permit decision in the Newmarket matter. In April 2014, NHDES rescinds the 2009 nutrient criteria.
2015–2018 — Negotiation replaces litigation as the primary channel. Municipalities and EPA meet directly, in part privately, to design an alternative permitting approach. The coalition's litigation costs exceed $6.3 million over the dispute's course.
2020–2021 — The bargain is struck. EPA takes public comment on a draft Total Nitrogen General Permit and issues its response to comments; the final permit takes effect February 1, 2021. A settlement agreement with the Conservation Law Foundation accompanies it, and Dover, Portsmouth, and Rochester agree to share permit costs — the arrangement that becomes the Municipal Alliance for Adaptive Management (MAAM).
2021–2025 — MAAM operates as the standing forum for monitoring, pollutant tracking, adaptive planning, and intermunicipal negotiation, later adding additional communities and districts. Portsmouth reports MAAM investment exceeding $1.8 million in monitoring and analysis, plus $1 million in Congressionally Directed Funds. Facility-level enforcement continues in parallel, confirming that collaboration operated alongside — not instead of — regulatory pressure.
2025 — PREP reports eelgrass in Great Bay proper at 22 acres, down from 855 acres in 2023, with estuary-wide extent at 211 acres. Portsmouth Harbor eelgrass increases roughly 67 percent in the same year. PREP attributes the decline to multiple interacting stressors and cautions that its survey maps extent, not cause.
2026 — No successor Great Bay nitrogen general permit has been issued. Under the 2020 permit's Part 6.2 continuation clause, and as described in Portsmouth and MAAM records, the first-cycle permit is best treated as administratively continued for already covered discharges while EPA develops the successor program. In March, CLF and the municipalities execute a Third Amendment extending the settlement to the earlier of February 28, 2031 or a final, unappealable successor permit. EPA has issued no final Residual Designation Authority determination, and the New Hampshire small MS4 general permit remains administratively continued. MAAM's first-term scientific synthesis is due at the end of 2026 — after the original permit term.
2. Why This Problem Matters
Great Bay tests whether collaborative adaptive governance can remain credible when ecological indicators worsen right as the legal framework is being renegotiated.
Great Bay matters because it tests a claim that collaborative water governance makes about itself: that parties who build durable institutions together will produce better environmental outcomes than parties who litigate. Between 2005 and 2020, the Great Bay nitrogen dispute moved from contested numeric criteria and a decade of permit appeals into a negotiated settlement architecture — the 2020 Total Nitrogen General Permit (effective February 1, 2021), the Municipal Alliance for Adaptive Management (MAAM), and a binding Conservation Law Foundation settlement. By the standard measures of collaborative governance, that architecture worked. It also has not yet restored the estuary.
The 2025 monitoring year made that gap impossible to set aside. PREP reported eelgrass in Great Bay proper falling from 855 acres in 2023 to 22 acres in 2025, with estuary-wide extent at 211 acres. This is a severe ecological warning signal, but it is not evidence that nitrogen regulation failed. PREP is explicit that its aerial survey records how much eelgrass grows where, not why it was lost, and identifies multiple interacting stressors — nitrogen, stormwater runoff, sediment, dissolved organic carbon, warmer water, wet spring conditions, and legacy pollution. Eelgrass in Portsmouth Harbor, a few miles seaward, increased by roughly 67 percent in the same year. A single-cause reading is not available on this record.
The legal frame entered its own period of stress at the same time. EPA had not issued a successor Great Bay nitrogen general permit by 2026. Under the permit's own Part 6.2 continuation clause, and as described in Portsmouth and MAAM records, the first-cycle permit is best treated as administratively continued for already covered discharges while EPA develops the successor program. 2026 is therefore not an endpoint but a holding period, in which the original framework, the settlement, and the MAAM process all remain active without a regulatory reset. The parties held their positions through it: in March 2026 CLF, Dover, Rochester, and Portsmouth executed a Third Amendment extending the settlement to the earlier of February 28, 2031 or a final, unappealable successor permit — while CLF simultaneously argued publicly that the eelgrass collapse shows regulators and municipalities have not done enough. That posture is neither opposition nor collaboration; it is participation backed by pressure.
What makes this case worth studying is the divergence itself. Great Bay currently holds governance durability, legal durability, and deep ecological uncertainty at once, and the first two cannot be cashed out as the third. The unresolved questions are structural rather than technical: EPA has issued no final Residual Designation Authority determination, the New Hampshire small MS4 general permit remains administratively continued, and the nonpoint share of the load is still addressed through voluntary municipal measures that the general permit does not enforce. Eelgrass decline cannot be answered through wastewater treatment alone. The case therefore asks whether a collaborative system can convert what it learns into harder obligation when the ecosystem deteriorates — or whether it can only keep the parties talking.
3. Interests of Key Stakeholders
| Knowledge | Alignment: Medium | Dynamic: Stalemate |
| Decision-Making | Alignment: Medium | Dynamic: Conflict |
| Impacted | Alignment: Medium | Dynamic: Shifting |
Interests moved from adversarial and legally polarized toward negotiated coexistence, then came under renewed strain. Between 2008 and 2014, regulators, municipalities, and CLF contested the science and the numeric standard through rulemaking, appeals, and litigation. Between 2015 and 2021, the same parties converted that conflict into a shared permitting and adaptive-management bargain. Since 2025, ecological decline has reopened the question of whether that bargain delivers, without any party leaving it. Alignment is best described as partial and conditional rather than settled.
The stakeholder structure of this case has changed shape twice, and the second change is still underway.
In the first phase, roughly 2008 to 2014, interests were organized around a scientific and legal question: whether total nitrogen was the driver of estuarine decline and what numeric limit, if any, should follow. Municipalities organized defensively as the Great Bay Municipal Coalition, contesting both the state's draft loading thresholds and EPA's move to put numeric limits in draft permits. Regulators were not aligned with each other; the state ultimately rescinded its own 2009 nutrient criteria in 2014, while EPA sustained its permitting position through appeal. CLF applied external legal pressure throughout. The knowledge community was itself contested terrain rather than a neutral referee, since the technical advisory process was where the disputed causal claim was being adjudicated. Interests in this phase were genuinely opposed and were pursued through litigation, rulemaking challenges, and congressional attention.
In the second phase, roughly 2015 to 2021, the same actors converted opposition into a negotiated structure without any of them abandoning their underlying positions. Direct negotiation between municipalities and EPA produced the 2020 Total Nitrogen General Permit and an accompanying settlement with CLF; Dover, Portsmouth, and Rochester agreed to share costs, and MAAM became the standing forum. What changed was not the interests but the venue and the instruments. Municipalities gained flexibility and staged investment; EPA gained enforceable point-source limits and a participating regulated community; CLF gained a binding contract it retained standing to enforce; the knowledge community gained sustained funding and a defined role.
The third phase began in 2025 and is unresolved. The eelgrass decline did not realign the parties into new coalitions, but it did reopen the question the bargain was meant to settle. CLF extended the settlement through March 2031 while simultaneously arguing publicly that regulators and municipalities have not done enough — participation and pressure at the same time, which is the posture most easily misread in this case. Municipalities face renewed cost exposure without a successor permit defining what they are committing to. The knowledge community carries an expectation it has not yet met, since MAAM's first-term synthesis is due only at the end of 2026. Residents have become an active interpretive constituency rather than a background one, asking directly whether prior investment was sufficient. No party has exited, and no party has declared satisfaction.
Whether interests converge or diverge from here depends primarily on whether the successor permitting process converts monitored learning into enforceable obligation. If it does, the current alignment is likely to hold. If it does not, the arrangement's weakest seam is the nonpoint share, which remains voluntary and unenforced under the general permit and is where municipal, regulatory, and advocacy interests are least reconciled.
4. Mapping the Problem Space
System type: complex · Boundary mismatch: institutional · What is contested: problem framing · Mis-framing: technical-only
The defining feature of this problem space is that no single boundary contains it — jurisdictional, hydrologic, regulatory, and disciplinary boundaries each cut it differently, and none of them aligns with the others.
The hydrologic boundary is the estuary and its watershed, which spans municipalities in two states and includes land uses no wastewater permit reaches. The regulatory boundary is far narrower: the Total Nitrogen General Permit binds wastewater treatment facilities, which are the tractable and measurable share of the load but not the dominant one. Nonpoint and stormwater sources — runoff, septic systems, fertilizer, legacy sediment — sit largely outside enforceable obligation, addressed through voluntary municipal measures that the general permit tracks but cannot compel. The stormwater side has its own separate and unresolved boundary: the New Hampshire small MS4 general permit remains administratively continued, and EPA has issued no final Residual Designation Authority determination. The institutional boundary is different again, running through EPA Region 1's permitting authority, state agency involvement, and municipal implementation capacity and appropriations, with MAAM constructed specifically to bridge a gap none of those three could close alone.
The disciplinary boundary matters as much as the legal one. Nitrogen loading is a wastewater engineering problem, land use and runoff are a planning and stormwater problem, and eelgrass response is an estuarine ecology problem involving light attenuation, sediment, dissolved organic matter, temperature, and residence time. Each field can be internally rigorous while producing an account the others cannot act on. The 2025 eelgrass decline made this concrete: the clearest public indicator of estuary health moved sharply in the wrong direction for reasons that are multi-stressor and not attributable to any single regulated quantity.
The single most contested element is problem framing — whether the case is fundamentally about nitrogen at all, and what follows if causation cannot be established with confidence. That question was litigated directly from 2008 through 2014 and has never been fully closed; the 2025 decline reopened it in a new form. But framing is not the only thing contested here. Risk is contested, in the specific sense of who bears the consequences of acting before the science is settled versus waiting while conditions worsen. Allocation is contested as well, both across municipalities sharing permit costs and between the point-source share carrying enforceable limits and the nonpoint share carrying none. These three are entangled rather than sequential, and a reader should not infer from the single selection above that framing is the only live dispute.
The same caution applies to the mis-framing entry. The recurring reduction has been technical — treating the estuary as a treatment-plant engineering problem solvable by facility upgrades — but two others operate alongside it. An economic-only framing appeared in the compliance-cost arguments of the litigation period, and a local-only framing recurs whenever municipal boundaries are treated as the unit of accountability for a watershed-scale outcome. Technical-only is the closest available single value, not a complete description.
5. Core Diagnostic Insights for Action
Institutional durability is not ecological recovery; flexibility remains principled only when learning can change enforceable commitments before ecological or legal lock-in.
Four diagnostic insights follow from this case, and they are stated as claims that could be shown wrong rather than as settled findings.
First: institutional durability is not ecological recovery, and the two must be assessed separately. Great Bay currently holds three different kinds of result at once. Governance durability is relatively strong — the parties stayed at the table across a permit cycle, a settlement extension, and an ecological shock. Legal durability is partial and unresolved — the permit is administratively continued rather than reissued, the successor program is undefined, and the stormwater and residual-designation questions remain open. Ecological success is not demonstrated. Collapsing these three into a single verdict, in either direction, is the most common analytical error available in this case.
Second: collaboration here did not replace regulation; it operated inside a standing enforcement shadow. The flexible arrangement was built on binding total-nitrogen limits for wastewater facilities, a settlement enforceable by an organization with standing and capacity to litigate, retained federal permitting authority including the individual-permit route, and an open citizen-suit pathway. Facility-level enforcement continued throughout the cooperative period. Any reading that treats this case as evidence that collaboration substitutes for enforceable obligation misdescribes the mechanism that made it hold.
Third: flexibility stays principled only while those backstops bite, and this case structurally resembles the arrangements where they have not. Collaborative, flexible environmental governance has a sobering record — particularly in nutrient management, where regimes relying on voluntary nonpoint commitments have repeatedly deferred or missed watershed targets while the enforceable point-source obligations held. Great Bay is built on exactly that structure: binding limits on the treatment facilities, voluntary municipally chosen measures for the larger nonpoint share. The relevant literature also locates cultural and relational capture in high-capacity, technically dense, repeat-player settings, which describes this forum precisely. The claim that Great Bay differs is therefore conditional and testable, not established.
Fourth: the distinguishing test is whether learning converts into obligation at a scheduled moment. A forum that produces monitoring, tracking, and shared analysis has done something real only if there exists a point at which what was learned becomes harder commitment. Public tracking makes shortfall visible without making it enforceable — visibility is a precondition for accountability, not a form of it.

Any of these would indicate that this case belongs with the arrangements it currently claims to differ from.
