6. Calculation of Limits <br /> <br />Categorical limits (40 CFR 465) were calculated for aluminum (465.35), steel <br />(465.15) and galvanized material (465.25) coil coating using average production <br />and flow data provided by Edcoat, LLC. in monthly Periodic Compliance Reports <br />submitted for the months of February 2022 through February 2023. The mass- <br />based standards for each of the categories were converted into concentration- <br />based standards and then summed up to determine the final categorical limit. <br />The Combined Waste Stream Formula (CWF) was used due to the air compressor <br />condensate waste stream deemed as dilution water, dilution being 1.105%. Once <br />categorical concentration-based limits were developed and CWF utilized, the <br />more stringent of the categorical and local limits were applied. Please see the <br />attached calculations for details. <br />7.
