The map
An illustrative plume map with pollutant views and synthetic wind playback, built around the proposed Inola smelter. Not an exposure prediction or a display of current weather.
What the map is built on
The supplied Protect Inola graphic cites the September 3, 2026 PSD application, Tables 2.1-1, B-1 and B-2. The specifications in the map were transcribed from the graphic, not independently verified against those tables. Colored bands are fixed annual illustrations, not the current plume or exposure zones. The school counter tallies synthetic wind directions near the approximate school bearing; it does not calculate plume arrival, concentrations, or actual school exposure.
Official application and review status (opens in a new tab)Three pollutants · Three distances
Tier I · Local
Fluoride
1.8–8 km · Illustrative band
OPA’s September 3 release proposes a potline fluoride cap of 0.64 lb per U.S. ton of aluminum, 37% below the original proposal. This is not a whole-facility annual total or evidence of approval. Deposition and exposure depend on emissions, weather, and other site-specific factors; the bands are not a regulatory dispersion study.
Tier II · Regional
SO₂ & NOx
15–60 km · Illustrative band
Sulfur and nitrogen oxides can form sulfate and nitrate aerosols. Site-specific modeling is needed to evaluate deposition and possible effects on Class I wilderness areas. The bands on this map do not establish that emissions reach them.
Tier III · Global
PFCs
No limit · Illustrative band
Perfluorocarbons can be released during anode effects in the smelting process. They are chemically inert in the lower atmosphere, with atmospheric lifetimes measured in thousands of years. This illustration does not estimate their emissions or climate impact.
