See EPA's PDF page to learn more. The metal finishing effluent
guidelines (40 CFR 433) were promulgated in 1983 and regulate
wastewater from wide variety of industries performing various
metal finishing operations. EPA estimates that there are
approximately 44,000 facilities performing various metal
finishing operations that discharge process wastewater directly
to surface waters or indirectly to surface waters through POTWs.
The metal finishing effluent guidelines are incorporated into
NPDES permits for direct dischargers or permits or other control
mechanisms for indirect dischargers. On July 15, 1983, this
regulation amended the pretreatment standards for existing
source electroplaters (electroplating PSES), 40 CFR Part 413. -
