Messer LLC processes crude carbon dioxide from a neighboring industry to produce food quality carbon dioxide. Messer LLC requirements were reviewed for necessary changes to ensure the industrial permit remains legally substantiated. After review of requirements and historical data, no pollutant limitations were adjusted. There have been no significant changes to the permit. If you should have any questions, please do not hesitate to contact me (574) 235-5798 or at sshane@southbendin.gov. Please let me know if I need to attend the Board Meeting to present this permit. Sincerely, Serena Lozano-Shane Pretreatment Manager City of South Bend Division of Environmental Services, Department of Utilities 3113 Riverside Drive South Bend, IN 46628 (574) 235-5798 sshane@southbendin.gov Enclosure(s) - Industrial Discharge Permit Board of Public Works Signature Page, Permit Briefing Memo, Part I- Effluent Limitation, - Agenda Request Form Wastewater Treatment Plant 3113 Riverside Drive South Bend, IN 46628 James Mueller, Mayor Phone 574-277-8515 Messer, LLC. Industrial Wastewater Discharge Permit page 7 of 41 Facility Description Messer, LLC. processes crude carbon dioxide from a neighboring industry to produce food quality carbon dioxide. The carbon dioxide comes from a feed gas line from the neighboring industry. The carbon dioxide is filtered and sent to a separator that helps remove the moisture. Then the carbon dioxide is chilled with ammonia and then sent to another separator that removes large water droplets in solution. The carbon dioxide is then compressed from 2 pounds per square inch to 60 pounds per square inch. The solution is then cooled with cooling water. A third separator removes moisture in the carbon dioxide and then is compressed to 300 pounds per square inch. The carbon dioxide then travels through a zinc oxide bed to remove the hydrogen sulfide that may be present. The carbon dioxide is cooled through the water cooler and is sent back through the scrubber. The scrubber removes the impurities in the carbon dioxide. The carbon dioxide is now at 320 pounds per square inch coming from the scrubber. PART I – EFFLUENT LIMITATION A. Sample Port and Collection Location 1. Sample Site Outfall #900 is located outside at the southwest corner of the facility inside the facilities fence in a controlled manhole. The sampler is set up next to the manhole and is locked up. A 24 hour composite sample is collected in this manhole of Messer's total discharge flow. Grab Samples are also collected in this manhole . 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 # 900: Parameter Daily Maximum Limit (mg/L) Monthly Average Limit (mg/L) Arsenic (mg/L) Report* Report* Cadmium (mg/L) Report* Report* Chromium (mg/L) Report* Report* Copper (mg/L) 3.0 0.6 Lead (mg/L) 1.5 1.0 Mercury (mg/L) 0.00019 -na- Nickel (mg/l) Report* Report* Oil and grease (mg/l) 300 -na- Oil and Grease TPH (mg/l) 100 -na- Silver (mg/L) Report* Report* Zinc (mg/L) 2.5 1.5 Messer, LLC. Industrial Wastewater Discharge Permit page 9 of 41 3. 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 PERMIT BRIEFING MEMO 1. Facility Description Messer LLC processes crude carbon dioxide from a neighboring industry to produce food quality carbon dioxide. The carbon dioxide comes from a feed gas line from the neighboring industry. The carbon dioxide is filtered and sent to a separator that helps remove the moisture. Then the carbon dioxide is chilled with ammonia and then sent to another separator that removes large water droplets in solution. The carbon dioxide is then compressed from 2 pounds per square inch to 60 pounds per sqaure inch. The solution is then cooled with cooling water. A third separator removes moisture in the carbon dioxide and then is compressed to 300 pounds per square inch. The carbon dioxide then travels through a zinc oxide bed to remove the hyrdogen sulfide that may be present. The carbon dioxide is cooled through the water cooler and is sent back through the scrubber. The scrubber removes the impurities in the carbon dioxide. The carbon dioxide is now at 320 pounds per square inch coming from the scrubber. The carbon dioxide is then refined to its finished product where it is stored until delivery to the customer. 2. Discharge description: Discharge is total facility flow (Condensation, Scrubber, Cooling Tower Blow down and Sanitary). From December 2022 to November 2023 Average Daily Flow: 37,941 gallons Maximum Daily Flow: 67,918 gallons 3. Sample Site Description Sample Site Outfall #900 is located outside at the southwest corner of the facility inside the facilities fence in a controlled manhole. The sampler is set up next to the manhole and is locked up. A 24 hour composite sample is collected in this manhole of Messer's total discharge flow. Grab Samples are also collected in this manhole. 4. Wastewater Treatment The pH of the water from the scrubber to the decarbonator is about 5.5- 5.6. The water is then pulled down through the media in the decarbonator as carbon dioxide is pushed up and the pH of the water is increased to 7.2-7.4. The water is then sent to the mixing tank where caustic is added to bring the final pH to 7.5. The effluent which consists of Cooling Tower Blow Down and Srcubber water is then sent through their oil/water separator that is located in the facilties maintenance garage and then mingles with their sanitary and finally is sent to the City of South Bend Sewer System. Wastewater treatment consists of a de-carbonator (which removes Carbon Dioxide) and pH neutralization. There is also an oil/water separator in the vehicle maintenance building. 5. Classification Messer LLC is classified as a Significant Industrial User (SIU) as defined in the South Bend Municipal Code. 6. Calculation of Limits Limits are applied from the South Bend Municipal Code directly to Messer LLC facility effluent. 7. Monitoring Frequency Monitoring frequencies are based on South Bend’s US EPA approved industrial pretreatment program monitoring plan. Messer LLC is classified as a B industrial user due to their waste flow of greater than 50,000 gpd and less than 100,000 gpd. 8. Operator Certification Industrial Operator Requirement: A-SO Industrial operator certification requirements are based on the criteria listed in Indiana Administrative Code, Title 327, 5-22-5. Determination of Messer’s industrial operator certification requirements is due to the use of de-carbonator to remove CO2 from the effluent to minimize the use of sodium hydroxide to applied with the effluent for pH neutralization.
