0:22-cv-01783
D. MinnesotaMar 29, 2024Background
- The Grand Portage and Fond du Lac Bands of Lake Superior Chippewa challenged the EPA's approval of Minnesota's 2021 revised water quality standards, claiming these revisions undermined protections for aquatic life, wild rice, and tribal treaty rights.
- Historically, Minnesota's water standards included numeric limits on certain pollutants, which incidentally protected sensitive uses like wild rice and aquatic life. The 2021 revisions replaced these numeric criteria with qualitative, narrative standards for industrial consumption and irrigated agriculture uses.
- The EPA approved these revisions, agreeing with the Minnesota Pollution Control Agency (MPCA) that statewide numeric criteria were no longer scientifically defensible or necessary, and that protections for aquatic life and wild rice remained in place under separate, unaffected standards.
- The Bands argued that the EPA failed to properly consider cumulative impacts, the effect on treaty rights, and that narrative standards are harder to implement and enforce, risking increased pollution.
- The case was decided on cross-motions for summary judgment. The court's review was highly deferential under the Administrative Procedure Act (APA), focused on whether the EPA's decision was arbitrary, capricious, or contrary to law.
- The court found the EPA's rationale scientifically reasonable, rejected extra-record evidence from plaintiffs, and held that protections for aquatic life, wild rice, and treaty rights remained via unaffected standards.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Removal of Numeric Criteria | Numeric criteria can and should be maintained; narrative standards are harder to enforce. | Numeric criteria are no longer scientifically defensible; narrative standards coupled with translators suffice. | Not arbitrary or capricious to remove numeric criteria based on scientific rationale. |
| Impact on Downstream Uses (Aquatic Life/Wild Rice) | EPA failed to ensure new standards won't harm these sensitive uses or perform sufficient analysis. | Separate unaffected standards continue to protect these uses; incidental loss is permissible. | EPA's holistic approach and reliance on existing criteria was not arbitrary or capricious. |
| Consideration of Tribal Treaty Rights | EPA did not adequately consider or consult Tribes on treaty-reserved rights, especially re: wild rice. | EPA did consult Tribes, summarized issues, and found protections remain under unaffected standards. | EPA's process, though limited, was sufficient under law; court defers to agency expertise. |
| State Implementation & Enforcement | EPA approval invalid due to Minnesota's history of poor enforcement of narrative criteria. | Enforcement/implementation is not a required factor in approving standards; focus is on standards themselves. | Enforcement issues are not a statutory factor for EPA approval; not a basis to overturn decision. |
