Plain English Guide to Regulations Federal Laws and Regulations Electroplating Categorical Standards (40 CFR 413) Electroplating Categorical Standards (40 CFR 413) Electroplating Categorical Standards (40 CFR 413) are applicable to wastewater from these six specific operations:
Most facilities that were initially covered by the Electroplating Categorical Standards (1984 compliance date for most facilities) were subsequently covered by the Metal Finishing Categorical Standards (1986 compliance date for most facilities). Excluded from the Metal Finishing rules are all existing indirect discharging job shops electroplaters and independent printed circuit board manufacturers. For these two groups of facilities, the Electroplating Standards still apply. All industrial facilities that discharge process wastewater to a stream or river or a city sewer system are covered by the NPDES program (for direct dischargers) or the General Pretreatment Regulations (40 CFR 403) (for indirect dischargers). For most affected facilities, the Electroplating Standards are administered by a local or state wastewater agency.

Metal Finishing Categorical Standards (40 CFR 433) The Metal Finishing Category covers wastewater from 46 unit operations: the six operations covered by the Electroplating Categorical standards, plus an additional 40 operations. If any of the six electroplating operations are present, then the Metal Finishing standards apply to wastewater from any of the 46 listed metal finishing operations. Also, all direct discharge electroplating and metal finishing facilities are covered by the Metal Finishing Categorical Standards (i.e., the Electroplating Standards apply only to indirect dischargers). Excluded from the Metal Finishing rules are all existing indirect discharging job shops electroplaters and independent printed circuit board manufacturers. For these two groups of facilities, the Electroplating Standards still apply. For most affected facilities, the Metal Finishing Standards are administered by a local or state wastewater agency.

Coil Coating Point Source Category (40 CFR 465) Coil coating typically involves cleaning, conversion coating, and painting the basis material. This regulation covers processes which perform any two or more of the three operations. The effluent limitations are based on the area actually exposed to process solutions. Usually this includes both sides of the metal strip. For most affected facilities, the Coil Coating Standards are administered by a local or state wastewater agency. The numerical pretreatment standards for the Coil Coating Category can be viewed by clicking HERE. The full text of the Coil Coating Categorical Standards (40 CFR 465) can be viewed by clicking HERE. General Pretreatment Regulations (40 CFR 403) The General Pretreatment Regulations affect all coating facilities that discharge process wastewater to a POTW. However, which specific provisions apply to any given facility depends on several factors:
