OWTS Challenges Require AAD Variance Appeal: No Futility Where AAD Has Independent Variance Authority; Facial Takings Claims Dismissed as Unripe

1. Introduction

In Nicholas DiBiccari v. State of Rhode Island et al. (R.I. Mar. 10, 2026), the Rhode Island Supreme Court addressed how and when a property owner may bring constitutional challenges to the Department of Environmental Management’s onsite wastewater treatment system (OWTS) regulations. Nicholas DiBiccari owned a vacant lot in Westerly and sought a DEM variance to install an OWTS to support a single-family residence. DEM denied the variance under 250 RICR 150-10-6.52(B)(2)(e)(9) because the lot’s groundwater depth from original ground surface was less than twelve inches (alleged to be zero).

Rather than appeal within DEM to the Administrative Adjudication Division (AAD), DiBiccari filed a three-count Superior Court action seeking declaratory, injunctive, and monetary relief: (1) as-applied takings claims (count one), (2) facial claims under takings, equal protection, and due process (count two), and (3) injunctive relief (count three). The Superior Court dismissed for failure to exhaust administrative remedies. The Supreme Court affirmed, while also holding the facial claims failed under Rule 12(b)(6) on independent grounds.

Key issues

  • Whether an OWTS variance applicant may bypass an AAD appeal as “futile” when DEM denies under a mandatory denial provision (Section 6.52(B)(2)(e)(9)).
  • Whether facial constitutional challenges avoid exhaustion yet still fail for lack of ripeness or failure to state a claim.
  • How DEM’s preliminary variance review under Section 6.52 differs from AAD’s variance authority under Section 6.53.

2. Summary of the Opinion

The Court drew a sharp procedural line:

  • As-applied claims (counts one and three): dismissal affirmed because DiBiccari failed to exhaust administrative remedies by not appealing to the AAD. The futility exception did not apply because the AAD evaluates under a different regulatory standard (Section 6.53) and may grant a variance notwithstanding DEM’s mandatory denial factors in Section 6.52.
  • Facial claims (count two): while facial constitutional challenges generally do not require exhaustion, DiBiccari’s specific facial theories still failed under Rule 12(b)(6): (a) the takings claim was unripe because the AAD had not rendered a final, discretionary decision on permissible use, (b) equal protection and substantive due process failed because the regulations involve no suspect class or fundamental right and are rationally related to groundwater protection, and (c) procedural due process failed because Section 6.53 provides a meaningful opportunity to be heard.

3. Analysis

3.1. Precedents Cited

A. Pleading and Rule 12(b)(6) framework

  • Fuller Mill Realty, LLC v. Rhode Island Department of Revenue Division of Taxation: confirmed that, on a motion to dismiss, courts look to the complaint’s “four corners.”
  • Chariho Regional School District by and through Chariho Regional School Committee v. State and Rein v. ESS Group, Inc.: reinforced the Supreme Court’s use of the same dismissal standard as the trial justice.
  • Pontarelli v. Rhode Island Department of Elementary and Secondary Education and Narragansett Electric Company v. Minardi: reiterated that a motion to dismiss tests sufficiency; allegations are assumed true with doubts resolved for plaintiff.
  • Multi-State Restoration, Inc. v. DWS Properties, LLC and Laurence v. Sollitto: applied the “beyond a reasonable doubt” standard for dismissal in Rhode Island.
  • Johnston Equities Associates, LP v. Town of Johnston: anchored de novo review for questions of law.
  • Evoqua Water Technologies, LLC v. Moriarty: supported affirmance on grounds different from those relied upon by the trial justice (used here for facial count two).

B. Exhaustion doctrine and futility exception

  • Richardson v. Rhode Island Department of Education and Arnold v. Lebel: stated the baseline rule that an aggrieved party must exhaust administrative remedies before suing.
  • Doe ex rel. His Parents and Natural Guardians v. East Greenwich School Department and Almeida v. Plasters' & Cement Masons' Local 40 Pension Fund: explained exhaustion’s institutional purposes—record development, agency expertise, and judicial economy.
  • Bellevue-Ochre Point Neighborhood Association v. Preservation Society of Newport County and DeLuca v. City of Cranston (mem.): recognized the futility exception but treated it as narrow.
  • Cullen v. Town Council of Town of Lincoln (quoting Gilbert v. City of Cambridge): supplied the controlling futility standard—futility requires near certainty of denial; the burden rests on the party claiming futility; doubts are resolved against it.
  • Murphy v. Zoning Board of Review of Town of South Kingstown: supported the Court’s role in interpreting regulatory language as a question of law.
  • Burns v. Sundlun: provided the pivotal distinction: exhaustion is generally required for as-applied constitutional challenges, but may be excused for facial challenges where agency fact development would not assist the court and where an agency ruling could moot the issue.

C. Facial challenges, ripeness, and takings

  • Key v. Brown University, Burns v. Sundlun, and Taylor v. Marshall: confirmed that facial constitutional attacks typically may proceed without administrative exhaustion.
  • Soundboard Association v. Federal Trade Commission: underscored the conceptual distinction between exhaustion and ripeness.
  • Alegria v. Keeney (quoting Pennsylvania Coal Co. v. Mahon): framed regulatory takings as regulation that “goes too far.”
  • Cranston Police Retirees Action Committee v. City of Cranston by and through Strom: treated state and federal Takings Clauses as coextensive for analysis.
  • Agins v. Tiburon: provided the “substantially advance legitimate state interests” / “deny economically viable use” formulation (as quoted by the Court).
  • Palazzolo v. Rhode Island (quoting Suitum v. Tahoe Regional Planning Agency): supplied the ripeness rule: a takings claim generally is not ripe until the land-use authority has used its procedures and discretion—including variance mechanisms—to define the regulation’s reach with reasonable certainty.

D. Equal protection and due process

  • Barrington Cove Limited Partnership v. Rhode Island Housing and Mortgage Finance Corporation: stated the general equal protection principle—similarly situated parties must receive similar treatment.
  • Mackie v. State (quoting Kleczek v. Rhode Island Interscholastic League, Inc.): clarified that equal protection does not require identical treatment of things “different in fact.”
  • Rhode Island Depositors Economic Protection Corporation v. Brown: anchored rational-basis review where no suspect classification is involved.
  • State v. Germane (quoting Washington v. Glucksberg): framed substantive due process as heightened protection only for fundamental rights/liberty interests.
  • Federal Hill Capital, LLC v. City of Providence by and through Lombardi (quoting In re Advisory Opinion to House of Representatives Bill 85-H-7748) and Riley v. Rhode Island Department of Environmental Management: described what counts as “fundamental rights” and how that affects the level of scrutiny.
  • Annicelli v. Town of South Kingstown: rejected the notion of a vested right to maximize property value—used to defeat the asserted “fundamental right” theory.
  • Resendes v. Brown, Mathews v. Eldridge, and Armstrong v. Manzo: supported the conclusion that the regulatory appeal process supplies a meaningful opportunity to be heard, satisfying procedural due process.

3.2. Legal Reasoning

A. Why the futility exception failed (and why Section 6.52 did not “bind” AAD)

DiBiccari’s core exhaustion argument was textual: because Section 6.52(B)(2)(e)(9) states a variance request “shall be denied” when groundwater depth is less than twelve inches, he claimed an AAD appeal would be pointless. The Court rejected this by construing the regulatory scheme as creating two separate decision points under two separate standards:

  • DEM preliminary review (Section 6.52): DEM staff evaluate the application for recommendation, with fifteen mandatory denial factors.
  • AAD appeal (Section 6.53): the AAD may “grant a variance” where (1) literal enforcement causes unnecessary hardship, (2) the OWTS will function as proposed, and (3) the variance will not be contrary to public interest, public health, or the environment.

In other words, the Court treated the AAD’s appeal authority as a distinct variance-granting mechanism not mechanically constrained by DEM’s preliminary mandatory-denial checklist. That structural reading defeated futility: because the AAD has discretion to grant relief, denial was not “certain (or nearly so)” under Cullen v. Town Council of Town of Lincoln.

B. Exhaustion still applies to as-applied constitutional claims

DiBiccari also argued that exhaustion should be excused because DEM/AAD cannot decide constitutional validity. The Court’s response tracked Burns v. Sundlun: even if agencies typically cannot adjudicate facial constitutional claims, exhaustion remains required for as-applied challenges because an administrative grant of a variance could moot the constitutional dispute and because agency proceedings can develop facts relevant to judicial review.

C. Facial challenges: allowed procedurally, but dismissed substantively

The Court acknowledged the Key v. Brown University/Burns v. Sundlun rule that facial challenges do not require exhaustion, yet held count two failed on the merits at the pleading stage.

(i) Facial takings: dismissed as unripe

Even framed facially, DiBiccari’s takings theory depended on the premise that affected lots cannot obtain any beneficial use. Under Palazzolo v. Rhode Island, takings claims generally are not ripe until the permitting authority has applied its procedures and discretion (including variances) to define what development is allowed with reasonable certainty. Because the AAD had not been asked to apply Section 6.53 to this property, the “reach” of the regulation was not yet known. The Court thus treated the case as the opposite of the “no doubt” scenario discussed in Palazzolo v. Rhode Island.

(ii) Equal protection and substantive due process: rational-basis regulation of non-suspect class; no fundamental right

The challenged classification—lots with groundwater depth under twelve inches versus those above it—was deemed a legitimate distinction between “things which are different in fact” under Mackie v. State. With no suspect class implicated and no fundamental right identified, the regulation was reviewed for rational basis. The Court found a rational relationship to the state’s groundwater-protection mandate (citing G.L. 1956 § 42-17.1-2(1), (11)).

For substantive due process, the Court rejected the attempt to characterize the ability to build (or maximize value) as a fundamental right, invoking Annicelli v. Town of South Kingstown (“no vested right” to maximize property value).

(iii) Procedural due process: meaningful opportunity to be heard exists via AAD

DiBiccari argued the scheme denied a hearing to prove public health compatibility. The Court pointed to the AAD appeal mechanism in Section 6.53 and to the constitutional baseline in Mathews v. Eldridge (quoting Armstrong v. Manzo) requiring a meaningful opportunity to be heard. Because the AAD process allows applicants to contest denial and litigate public-health/environmental criteria, procedural due process was satisfied.

3.3. Impact

  • Clarifies DEM/AAD division of labor: the decision treats Section 6.53 as an independent, discretionary variance pathway. Litigants cannot assume DEM’s preliminary mandatory-denial factors dictate the AAD outcome.
  • Narrows “futility” in environmental permitting: applicants must show near-certain denial; mandatory language at the DEM stage will not establish futility if an appellate body has separate discretion to grant relief.
  • Reinforces “final decision” ripeness for takings: even when labeled facially, a takings claim tied to alleged loss of all use will be dismissed if a variance authority has not been invoked.
  • Provides a roadmap for constitutional pleading: equal protection and substantive due process attacks on technical environmental thresholds will typically face rational-basis review and require more than generalized claims of unfairness or loss of value.
  • Practical litigation consequence: parties challenging OWTS denials should expect courts to require an AAD record before entertaining as-applied constitutional claims, and should anticipate ripeness defenses to premature takings theories.

4. Complex Concepts Simplified

Exhaustion of administrative remedies
You must use the agency’s built-in appeal process before going to court, so the agency can apply its expertise and build a record.
Futility exception
You may skip the agency process only if denial is virtually guaranteed. A “likely” loss is not enough; it must be almost certain.
As-applied vs. facial constitutional challenges
As-applied challenges argue a rule is unconstitutional in how it was applied to a specific person/property. Facial challenges argue the rule is unconstitutional in all, or nearly all, applications.
Ripeness (especially in takings)
A claim is “ripe” when the court can decide it based on a sufficiently final and concrete government decision. In land-use/takings cases, ripeness often requires pursuing available variances so it is clear what development is actually allowed.
Rational-basis review
If no suspect class or fundamental right is involved, the government only needs a rational reason for the rule. Groundwater protection is a classic rational basis for OWTS regulation.
Procedural due process
The Constitution generally requires fair procedures—notice and a meaningful chance to be heard—not a guarantee of a favorable outcome. An administrative appeal hearing commonly satisfies this requirement.

5. Conclusion

DiBiccari establishes a clear procedural and substantive template for challenges to Rhode Island OWTS regulations: (1) as-applied constitutional claims must proceed through the AAD because Section 6.53 supplies independent discretion to grant a variance, defeating “futility” arguments based solely on DEM’s mandatory-denial provisions; and (2) even though facial challenges need not be exhausted, takings claims may still be dismissed as unripe absent a final variance determination, while equal protection and due process claims will fail where the regulation rationally advances groundwater protection and the AAD process provides a meaningful hearing opportunity.
