Trigger predicate
When this evaluates true for a parcel, the law's preempted fields take precedence over base zoning.
parcel.is_adjacent_to_bwcaw == TruePreempted fields
2 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
review_type | require | usfs_bwcaw_consultation_and_mineral_withdrawal_check | The BWCAW (1.1M acres) and adjacent Mining Protection Area within Superior National Forest are subject to a 20-year federal mineral withdrawal (PLO 7917, Jan. 2023) covering ~225,000 acres of the Rainy River Watershed. Local zoning along the wilderness boundary (Cook, Lake, St. Louis counties) cannot authorize uses that conflict with BWCAW Wilderness Act protections. |

Citation
Authority source
BWCAW Act of 1978 (Pub. L. 95-495); 36 CFR Part 293; Public Land Order 7917 (Jan. 26, 2023 — 20-year mineral withdrawal); coordinated with Minn. Stat. § 84.523 (state Mining Protection Area)
Research notes
Federal-primary overlay captured at state-overlay scope because it gates land use in three NE Minnesota counties. The 2023 mineral withdrawal halted Twin Metals' proposed copper-nickel mine pending the 20-year review. State-level coordination via Minn. Stat. § 84.523. Per-parcel geographic predicate keyed to USFS BWCAW boundary + mineral withdrawal polygon. Federal conflict check enabled (federal primacy).
