Metal and Metal Fabricators Branch

The Metal and Metal Fabricators Branch (two-digit SIC Codes 33 through 37) of the Environmental Permits Division (EPD) is a multi-media industrial permitting branch whose primary function is to permit those industries (New and Existing) that are subject to Federal and State Wastewater (NPDES, Pretreatment, Stormwater, etc.) and Air Regulations (PSD, Title V, Synthetic Minor, Construction, etc.) whether the regulations that the facility is subject to are for Categorical Standards (MACT, BACT, Federal Effluent Guidelines, etc.) or a significant industrial contributing pollutant facility (not subject to a Federal Categorical Standard but significant enough to impact the environment).
