Prince William Sound spill vs Kerr-McGee legacy sites

Two real, published enforcement settlements, lined up. Every figure below is public record; the head-to-head is computed at build time over those real numbers. Penalty bars share one log scale, so they read across the gutter.

Prince William Sound spill

Exxon (Exxon Valdez) · Alaska
~$1 billion
settlement · log scale, $16.5M to $14.7B

The settlement that reset the price of an oil spill.

After the 1989 tanker grounding fouled 1,300 miles of Alaskan coastline, the 1991 settlement combined a $900 million civil recovery paid over ten years with $100 million in criminal restitution.

These are landmark settlements, not live ECHO facility records. Day-to-day compliance metrics - quarters in noncompliance, formal-action counts, last inspection - are not part of a settlement figure; they join per facility from the ECHO Exporter (loadFacilities() in src/lib/source.ts). See the Methodology for what is real versus illustrative on this site.
