Facility Description Imagineering Finishing Technologies engages in corrosion protection, plating, and finish surface coatings of various metal alloys. Imagineering conducts Abrasive, solvent and/or chemical cleaning of alloy surfaces prior to treating surfaces with phosphate (manganese or zinc) or chromium based compounds. Final surface treatment also include electroless nickel, conversion of aluminum, or painted materials. The process lines are named for the process and for the tank size in the line. For example, the 300 line has 300 gallon tanks. Imagineering facility employs 88 employees and operates 3 shifts, 5 days per week. 2. Discharge description: All wastewater is ultimately discharged through the final discharge point known as site SS1. Wastewater is segregated into two outfalls. Concentrates and dead rinses are generated from different processes (Phosphating, Acid Etching, and Electroless Nickel Plating), and are batch treated on -site and discharged through site SS1 or shipped off site for disposal. Water from the overflowing rinses from the different processes are discharged through SS without treatment. The Passivation line is the source of hexavalent chrome in the wastewater. The Passivation line consists of concentrates and overflowing rinses only. Wastewaters produced in the Passivation process are also batch treated on -site and discharged through site SS1 or is shipped off site for disposal. Estimated average process discharge flow is: 30,914 gpd with an estimated maximum process discharge of 50,526 gpd. Air compressor blow down, boiler blow down, water softener backwash, and RO backwash are discharged directly to the sanitary sewer without treatment. 3. Sample Site Description SS1 is located outside the main facility in a locked shed which is attached to the west wall of the building. The wastewater discharge flows through a weir box for flow measurement in the shed prior to discharge. The sample is collected in the discharge pipe after the final chamber of the weir box. SS 1 is both end -of -process and end -of -pipe (sanitary waste excluded). 4. Wastewater Treatment Wastewater treatment consists of chemical precipitation, flow equalization, neutralization, polymer flocculation, settling, filtration and chrome reduction. 5. Classification Imagineering Finishing Technologies is a Categorical Industrial User (CIU). Specifically, Imagineering Finishing Technologies is a metal finisher covered by (CFR-433w 5 f 1 41,1' 1 (71 R 3„ Jj L � �"� due to the electroplating and metal finishing operations. Imagineering Finishing Technologies is categorized as a B industry. 6. Calculation of Limits Limits for SS 1 are calculated and applied as "What You Need Is What You Get" or from 40 C "I" i 00t''F .33 � �" �� t�o the process flow which is categorical, if the limits are more stringent. 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.

SS 1 is located outside the main facility in a locked shed which is attached to the west wall of the building. The wastewater discharge flows through a weir box for flow measurement in the shed prior to discharge. The sample is collected in the discharge pipe after the final chamber of the weir box. 2. Any discharge of water or waste having a pH lower than 6.0 S.U. or a pH higher than 11.0 S.U. is prohibited. In addition, the permittee's wastewater discharge shall not exceed the following effluent limitations: Effluent limitations for Sample Site Outfall # SS 1: Parameter Daily Maximum Limit (mg/L) ,Monthly Average Limit (mg/L) Arsenic (mg/L) Report* Report* Cadmium (mg/L) Report* Report* Chromium (mg/L) 2.77 1.71 Copper (mg/L) 3.38 0.8 Cyanide (mg/L) 1.2 0.65 j Lead (mg/L) Report* Report* Mercury (mg/L) 0.00019 -na- Nickel (mg/L) 3.98 0.8 Oil and grease (mg/1) 300 -na- ,Oil and Grease TPH (mg/1) 100 -na- Silver (mg/L) Report* Report* TTO (mg/1) 2.13 -na- Zinc (mg/L) 2.61 1.48 *Note: In accordance with the City of South Bend's "What You Need Is What You Get" allocation method, local Daily Maximum and Monthly Average limits have only been developed for those pollutants that have been observed at or above certain concentrations in each Significant Industrial User's wastewater discharge. If "Report" appears on the table, it has been determined that an allocation of this pollutant is not necessary. The permittee shall compare any monitoring data for these pollutants with the screening table in Part I (3) below. If pollutant concentrations above the screening levels are observed, a local Daily Maximum and/or Monthly Average limit may be developed for that pollutant. Imagineering Enterprises, Inc. Industrial Wastewater Discharge Permit page 1 of 41 Please be aware that Federal Categorical Limits are still in effect, as required by '1; 1 * * 40 is R 43 3 1 i" For pollutants that do not have local limits in the table above, the permittee is still required to comply with any applicable categorical standards, below. ;Parameter iDaily Maximum (mg/L) Monthly Average Limit (mg/L ,Cadmium (mg/L)* 0,610� l l (h26 Q.07 Lead (mg/L)* �0.69 0.43 'Silver (mg/L)* 0.43 0.24 s n d lra.. per � a... to ��a q �q 4 0 a" R 43 U7 a a. Daily Maximum Lini t means the maximum allowable discharge limit of a pollutant during a calendar day or any 24-hour period that represents a calendar day. Where Daily Maximum Limits are expressed in units of mass, the daily discharge is the total mass discharged over the course of the day. Where Daily Maximum Limits are expressed in terms of a concentration, the daily discharge is the arithmetic average measurement of the pollutant concentration derived from all measurements taken that day. In the case of samples collected by the grab method, the daily maximum shall be applied as an Instantaneous Maximum Allowable Discharge Limit or as an Instantaneous Minimum Allowable Discharge Limit as follows: i. Instantaneous Maximum Allowable Dischar e Limit — shall mean the maximum concentration or loading of a pollutant allowed to be discharged at any time, determined from analysis of any discrete or composite sample collected, independent of the industrial flow rate and the duration of the sampling event. ii. Instantaneous Minimum Allowable Discharge Limit — shall mean the minimum concentration of a pollutant allowed to be discharged at any time, determined from analysis of any discrete or composite sample collected, independent of the industrial flow rate and the duration of the sampling event. The lower pH limit is applied as an Instantaneous Minimum Allowable Discharge Limit. b. Mon Lbl_ver t means the maximum allowable average of daily discharges over a calendar month, calculated as the sum of the concentrations of all daily discharges measured during a calendar month divided by the number of daily discharges measured that month.
