554 F.Supp.3d 1282
N.D. Ga.2021Background
- This case challenges the U.S. Army Corps of Engineers' (Corps) 2017 adoption of an updated Apalachicola‑Chattahoochee‑Flint (ACF) River Basin Master Water Control Manual (WCM) and associated Final Environmental Impact Statement (FEIS) and Water Supply Storage Assessment (WSSA), which reallocates 254,170 acre‑feet of Lake Lanier conservation storage to accommodate Georgia withdrawals.
- Plaintiffs: State of Alabama (multiple APA, Water Supply Act, RHA, NEPA claims) and environmental groups (NWF, Florida Wildlife Federation, Apalachicola Riverkeeper — NEPA claim). Defendants: U.S. Army Corps, State of Georgia, and Georgia water providers. Court granted summary judgment to Defendants and denied Plaintiffs'.
- Core substantive dispute: whether the Corps lawfully exercised its authority (under the Rivers and Harbors Acts and Water Supply Act) to (1) reallocate storage for direct withdrawals from Lake Lanier without prior congressional approval and (2) adopt the WCM given environmental impacts assessed under NEPA.
- The Corps concluded the reallocation would not cause a "major structural or operational change" nor "seriously affect" authorized project purposes, modeled system‑wide impacts (hydropower, navigation, flood control, recreation, fish/wildlife), and selected Alternative 7K (the PAA) after NEPA review and consultation under ESA.
- The court applied Chevron/deferential APA review, giving substantial deference to the Corps' technical judgments and methodology (storage accounting, operational metrics, choice of baseline/no‑action alternative, and alternatives screening), and found the Corps' decisions reasonable and adequately explained.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Corps violated Water Supply Act by reallocating 254,170 acre‑feet without Congress | Alabama: reallocation is a "major operational change" and "seriously affects" authorized purposes, so statutory approval required | Corps: statute terms ambiguous; measured impacts by actual withdrawals/returns and system operations, not storage percentage; reallocation is within discretionary authority | Held for Corps — Corps' interpretation reasonable; reallocation not a major change nor seriously affecting purposes |
| Whether Corps unlawfully reordered project purposes under Rivers & Harbors Acts | Alabama: Corps elevated water supply over original multi‑purpose authorization | Corps: Eleventh Circuit found water supply an authorized purpose; Corps reasonably balanced purposes consistent with congressional intent and technical analysis | Held for Corps — no unlawful abandonment or reordering; Corps' balancing entitled to deference |
| Whether FEIS violated NEPA (baseline, purpose/need, alternatives, impacts, mitigation) | NWF/Alabama: FEIS used improper historical baseline, narrowed purpose/need, failed to analyze reasonable alternatives and impacts (direct/indirect/cumulative), and deferred mitigation | Corps: NEPA satisfied — used current operations as no‑action baseline, purpose/need reasonably framed, screened and analyzed feasible alternatives, thoroughly modeled impacts and mitigation measures, and explained choices | Held for Corps — FEIS met NEPA procedural requirements; analysis not arbitrary or capricious |
| Whether Corps violated APA by departing from its own water‑quality policy without explanation | Alabama: Corps failed to acknowledge and explain departure from water‑quality guidance | Corps: Corps acknowledged guidance, disclosed impacts, explained tradeoffs (water supply benefits outweigh impacts), and pointed to state NPDES role for mitigation | Held for Corps — Corps provided adequate explanation; decision not arbitrary or capricious |
