PART I – EFFLUENT LIMITATION A. Sample Port and Collection Location 1. Sample Site #323 B is located inside the main facility after the indoor final weir tank on the west wall of the wastewater treatment room. Wastewater flows through the weir tank for flow measurement prior to discharge. Grab samples are collected from the flow out of the weir tank, and 24-hour composite samples are collected from the discharge pipe after the weir tank. 2. The location of Sample Site Outfall # 323 A is an outdoor manhole on the west side of the building and south of the outside door to the production area. Effluent Limitations are in effect for Outfall # 323 A and wil be sampled if the Control Authority deems it necessary. 3. 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 # 323 A & # 323 B: Parameter Daily Maximum Limit (mg/L)Monthly Average Limit (mg/L) Arsenic 1.0 0.3 Cadmium Report*Report* Chromium 2.7 1.68 Copper 3.3 1.2 Cyanide 1.18 0.64 Lead 0.68 0.42 Mercury 0.00019 -na- Nickel 3.9 1.2 Oil & Grease 300 -na- Oil & Grease, TPH 100 -na- Silver Report* Report* TTO 2.1 -na- Zinc 2.57 1.46 Pioneer Metal Finishing, LLC Industrial Wastewater Discharge Permit page 8 of 44 *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. Please be aware that Federal Categorical Limits are still in effect, as required by 40 CFR 433.17. For pollutants that do not have local limits in the table above, the permittee is still required to comply with any applicable categorical Parameter Daily Maximum (mg/L) Monthly Average Limit (mg/L) Cadmium 0.11 0.07 Silver 0.42 0.23 a. Daily Maximum Limit 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 Discharge 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. Monthly Average Limit 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. Pioneer Metal Finishing, LLC Industrial Wastewater Discharge Permit page 9 of 44 4. Discharge Screening Level Limitations have been established to evaluate the need for a limitation for pollutants that are not listed in the Effluent Limitation section of the permit. If a permittee has no limit for a particular pollutant, but observes, through monitoring and analysis, a concentration of that pollutant greater than the listed Discharge Screening Level concentration found in the table below, the permittee shall notify the Control Authority. This notification shall be made in writing within five days of observing the pollutant concentration. Parameter Daily Maximum Screening Level (mg/L) Arsenic (mg/L) 0.2 Cadmium (mg/L) 0.1 Chromium (mg/L) 2.0 Copper (mg/L) 0.3 Lead (mg/L) 0.3 Nickel (mg/L) 0.3 Silver (mg/L) 0.2 Zinc (mg/L) 0.3 3 PERMIT BRIEFING MEMO 1. Facility Description Pioneer Metal Finishing (Pioneer) is a job shop and operates on one shift, 10-12 hours per day, on a seven day per week period. Pioneer engages metal finishing activities including anodizing and electroless nickel plating of customer supplied parts, as well as masking/painting, and chem film. Chemicals utilized in Pioneer’s processes include various dyes, seals, sulfuric acid, nitric acid, hydrochloric acid, caustic soda, nickel acetate, PTFE, Alodine, alkaline soaps, and electroless nickel solution. 2. Discharge description: Discharge to Sample Site # 323 (A&B) is metal finishing process water combined with boiler blowdown and non-contact cooling water. Boiler blowdown discharge is minimal at 5 gallons per day. Non-Contact Cooling water amounts change seasonally. Pioneer uses RO treated water in process lines and channels the RO backwash to a process rinse tank. Metal finishing wastewater originates at each of the rinse tanks which are situated between process tanks. Since Pioneer is a job shop, volume of discharge can vary significantly. From January 1, 2021 to May 31, 2022 Wastestream Average gpd Max gpd Non-Contact Cooling Water 303 1,500 Total Flow 18,827 78, 357 3. Sample Site Description Sample Site # 323 B is located inside the main facility after the indoor final weir tank on the west wall of the wastewater treatment room. Wastewater goes through the weir tank for flow measurement prior to discharge. Grab samples are collected from the flow out of the weir tank, and 24-hour composite samples are collected from the final discharge pipe after the weir tank. Pioneer requested to move the monitoring point indoors in the letter dated September 12, 2020. Pioneer commissioned “Bob Frame Plumbing” to camera the line between the Sample Site Outfall # 323 A and #323 B and certify that there were no inlets between the monitoring points. The location of Sample Site Outfall # 323 A is an outdoor manhole on the west side of the building and south of the outside door to the production area. The Control Authority requires Pioneer to maintain this sample site including the flowmeter cable for unannounced monitoring if the Control Authority deems it necessary. The Control Authority reserves the right to re-institute the Sample Site Outfall #323 A as Pioneer’s only sampling location if deemed appropriate. 4 4. Wastewater Treatment Wastewater treatment consists of metal precipitation with coagulation and flocculation for nickel baring wastestreams. The remaining wastewater is treated via pH adjustment only. Pioneer generates hazardous, nonhazardous and special wastes and these are shipped off site for disposal. These wastes include: electroless nickel solution, PTFE, sand blasting media, nitric acid, alkaline etch, electroless nickel stripping solution, spent chemical baths, dyes and MEK. Pioneer is a large quantity hazardous waste generator. 5. Classification Pioneer is classified as a Categorical Industrial User (CIU) as defined in the South Bend Municipal Code. Specifically, Pioneer is classified as a metal finisher covered by 40 CFR 433.17 (PSNS) due to the anodizing and electroless nickel plating operations. Pioneer is categorized as an B industry per the City’s Industrial Pretreatment Program. All CIU’s with process discharge are defined as Category B at a minimum. 6. Calculation of Limits Wastewater discharged at Outfall 323 A & B is subject to the Metal Finishing Categorial Standard at 40 CFR 433.17. The more stringent of Chapter 17 of the City South Bend Municipal Code limits (local limits) or the limits provided in 40 CFR 433.17 with a combined wastestream formula modification have been applied. The combined wastestream formula for Pioneer is based on wastewater flow averages from January 1, 2021 to May 31, 2022. The average dilution wastewater from this timeframe was 303 gpd, and average total wastewater flow at Outfall #323 (A&B) was 18, 827 gpd, amounting to a 1.61% dilution factor. The combined wastestream formula has been calculated in accordance with 40 CFR 403.6 (e) and applied to end of process, local limits were applied at end of pipe. 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: C Industrial operator certification requirements are based on the criteria listed in Indiana Administrative Code, Title 327, 5-22-5.
