Facility Description Imagineering Finishing Technologies engages in Chemfilm Line (Alodine), zinc phosphate metal finishing, zinc manganese metal finishing, and chromate passivation of panels, parts, and pieces. The finished parts are shipped off site. Imagineering operates between the hours of 9:00 PM to 5:00 PM. There are 86 employees who work in staggered shifts lasting 8.5 and 10 hours each with no anticipated seasonal variation in production. 2. Discharge description Imagineering discharge is split into wastewater that undergoes pretreatment and is discharged through the sampling location, and wastewater that is not pretreated and is discharged directly to the sewer. The only wastewater that is discharged at the sampling location is the wastewater that undergoes pretreatment. Wastewater that is discharged directly to the sewer includes: boiler blow down, water softener backwash, sanitary waste, and RO backwash brine water. Wastewater that undergoes pretreatment before discharge includes Chromate Passivation line rinse waters and concentrates, Zinc Phosphate line rinse waters and concentrates, Zinc Manganese line rinse waters and concentrates, Chemfilm (Alodine) line rinse waters and concentrates, and air scrubber pollution control wastewater. Industrial process waters discharge to Outfall 260 via a weir box. For compliance sampling, 24 hour flow proportional composite samples are pulled from the weir box via a composite sampler. Discharge totalizer numbers are documented daily. The boiler sump discharge line has a paddle wheel totalizer that is used to determine blowdown and reverse osmosis brine flow. This water flows to the sanitary line. RO softener backwash is metered and discharged to the sanitary line as well. Imagineering reports that chromium, copper, nickel, and zinc are present in its wastewater. Imagineering suspects that lead and silver may be present as well. From July 2021 to July 2022 Average Process Flow: 25, 242 gpd Daily Maximum Process Flow: 46,919 gpd 3. Sample Site Description Sample Site Outfall at Site #260 is located at the east end of the building. The sample site is end-of-pipe; only process waters and pollution control wastewaters are discharged from the sampling site. Therefore, there is no need for using the combined wastestream formula or any other modification. 4. Wastewater Treatment Wastewater treatment consists of chemical precipitation, flocculation, filtration, flow equalization, neutralization and pH adjustment, sumps, and spill prevention. 4 5. Classification Imagineering Finishing Technologies is classified as a Categorical Industrial User (CIU). Specifically, Imagineering Finishing Technologies is classified as a metal finisher covered by 40 CFR 433.17 (PSNS) due to the electroplating and metal finishing operations. Imagineering Finishing Technologies is categorized as a B industry per the City’s Industrial Pretreatment Program based on the requirement that all categorical industries be considered Class B at a minimum. 6. Calculation of Limits Wastewater discharged at outfall 260 is subject to the Metal Finishing Categorical Standards at 40 CFR 433.17 (PSNS). The more stringent of limits provided in 40 CFR 433.17 or Chapter 17 of the City of South Bend Municipal Code have been applied without modification. 7. Monitoring Frequency Monitoring frequencies are based on South Bend’s US EPA approved Industrial Pretreatment Program monitoring plan. 8. Industrial Operator Certification Requirement Operator Certification Requirement: B Industrial operator certification requirements are based on the criteria listed in Indiana Administrative Code, Title 327, 5-22-5. All industrial users subject to federal categorical regulations are required to submit reports signed by an operator certified in the State of Indiana with at least a B certification, regardless of existing treatment complexity.
