Reading these numbers

These are regulatory records, not measurements of pollution. Most facilities appear because they hold a permit or file reports, and most of them are compliant; a listing is not a claim that a facility has polluted anything. Compliance status and penalties are the EPA's own determinations in data retrieved Oct 9, 2026. Distances are from the center of Grass Valley as the Census Bureau records it. The Data page explains where each record comes from and how it can mislead.
