The Enforcement Map filtered to the captive feedlot subset only — JBS Five Rivers (packer-owned) and the major corporate chains (Cactus Feeders, Friona Industries, Bar-G, Adams Land & Cattle, Simplot, Pinal, Champion). Each yard is colored by EPA ECHO compliance tier (last 12 quarters of NPDES). The Big Four packing plants are shown in grey for spatial reference.
