Carlo Demma, Physical Scientist (Env.) 2. Valeria, Apolinario, Environmental Engineer Other Attendees: 1. Brandon Whitman, Corporate HES Manager, SunCoke Energy 2. Ralph Kremer, General Manager, SunCoke Energy 3. Edward Glass, Operations Manager, SunCoke Energy 4. Chris Taylor, Operations Area Owner, SunCoke Energy 5. Brandon Koch, Heat Recovery Area Lead, SunCoke Energy Contact Email Address: Brandon Whitman - BEWHITMAN@SUNCOKE.COM Purpose of Inspection: EPA conducted this inspection to determine compliance with the air pollution requirements of the Illinois State Implementation Plan (IL SIP), and SunCoke Company's Construction Permit No: 06070020 relating to charging fugitive emissions and coke oven door regulations. Facility Name: SunCoke Energy Granite City Operations Facility Location: 2585 Edwardsville Road, Granite City IL 62040 Date of Inspection: September 7, 2023 Facility Type: Stationary heat recovery coal carbonization facility. Regulations Central to Inspection: The facility is subject to SunCoke Company's Construction Permit No: 06070020 and 40 CFR 63.303(d)(1), which states, the owner or operator shall not discharge or cause to be discharged to the atmosphere from charging operations any fugitive emissions that exhibit an opacity greater than 20 percent. Pursuant to the Illinois SIP at 35 IAC 212.443(d)(1), and SunCoke Company's Construction Permit No: 06070020, no person shall cause or allow visible emissions from more than 10 percent of all coke oven doors at any time. Arrival Time: 8:00 AM Departure Time: 9:30 AM Inspection Type: Unannounced Inspection Announced Inspection OPENING CONFERENCE Presented Credentials Stated authority and purpose of inspection Provided Small Business Resource Information Sheet Small Business Resource Information Sheet not provided. Reason: Not a small business. Provided CBI warning to facility The following information was obtained verbally from Brandon Whitman and Ralph Kremer unless otherwise noted: Process Description: SunCoke - Granite City (SunCoke) operates 120 ovens arranged in three 40-oven batteries at this site, labeled A, B, and C Battery. Coal is placed inside the one hundred twenty (120) nonrecovery coke ovens, and is then heated by recirculating combusted gas, but can also be supplemented by natural gas. The combusted flue gas is directed through heat recovery steam generators (HRSGs) where the residual heat is extracted, and steam is produced. The batteries are referred to as "non-recovery" and are operated under constant negative pressure, with emissions controlled by one lime spray dryer desulfurization unit (FGD) and one baghouse that removes entrained ash. Carbon is injected into the gas stream upstream of the spray dryer absorber to remove mercury. All waste gas emissions exhaust through one main stack, and occasionally through some of the seven bypass vent stacks distributed over the three batteries. One HRSG typically serves 20 ovens when gas sharing is not available. After coal carbonization is complete, the finished coke is pushed from the oven, quenched with water, screened to remove very fine material and delivered to the customer. Staff Interview: SunCoke is preparing for a full FGD maintenance outage scheduled for October 3, 2023. SunCoke's West Extractor (Coke Side) has a baghouse filter attached to it, Page 2 of 5 Facility Name: SunCoke Energy Granite City Operations Facility Location: 2585 Edwardsville Road, Granite City IL 62040 Date of Inspection: September 7, 2023 whereas the East Extractor does not. SunCoke only runs the East Extractor the minimum extent possible to ensure that it still operates correctly in the event of a malfunction or equipment failure of the West Extractor. The East Extractor typically operates once per week. SunCoke has begun filling the port hole openings on each oven and has also prioritized the missing Kaowool insulation, and door damages identified in EPA's May 16, 2023 inspection report. TOUR INFORMATION EPA Tour of the Facility: Yes Photos and/or Videos: were taken during the inspection. EPA photographed a degraded door on Oven 92. The upper left corner of the jam of the door was fully melted (Photo 1). EPA did not notate any visible emissions associated with the damaged door. EPA's second inspector recorded video of all coal charging runs (Attachment A). Field Measurements: were taken during this inspection. EPA performed Alternative Method - 082 (DCOT) on the Pusher Charger Machine (PCM) baghouse stack and its associated fugitive emissions while charging. Data Collected and Observations: EPA's primary goal was to witness the push and resultant charge of five ovens at the B and C Batteries. On-site opacity observations were conducted in accordance with EPA Alternative Method 082 on the PCM stack and its associated fugitive emissions at the Facility during the morning of September 7, 2023. SunCoke charged 5 ovens while EPA was on-site. Visible emissions were analyzed in accordance with EPA Alternative Method 082. Each production run took about 8-minutes to complete; EPA analyzed the highest opacity in a 6-minute interval during each run. The results of each 6-minute observation run are indicated below: 1. 16% opacity on a six-minute average for run #1 on B Battery, Oven 80 (Attachment B). Start: 8:22 AM Stop: 8:30 AM Coal charge: 42.5 tons 2. 9% opacity on a six-minute average for run #2 on C Battery, Oven 88 (Attachment C). Start: 8:33 AM Stop: 8:40 AM Coal charge: 45.0 tons 3. 20% opacity on a six-minute average for run #3 on C Battery, Oven 96 (Attachment D). Start: 8:40 AM Stop: 8:48 AM Coal charge: 44.5 tons 4. 18% opacity on a six-minute average for run #4 on C Battery, Oven 104 (Attachment E). Start: 8:50 AM Stop: 9:00 AM Coal charge: 43.5 tons 5. 9% opacity on a six-minute average for run #5 on C Battery, Oven 120 (Attachment F). Start: 9:03 AM Page 3 of 5 Facility Name: SunCoke Energy Granite City Operations Facility Location: 2585 Edwardsville Road, Granite City IL 62040 Date of Inspection: September 7, 2023 Stop: 9:11 AM Coal charge: 42.5 tons All Visible Emission Observation Reports are included in Attachments B to F. CLOSING CONFERENCE Provided U.S. EPA point of contact to the facility. Concerns: After the C-Battery was pushed and ovens 96 and 104 were charged, the SunCoke PCM operator struggled to latch the door back onto the Battery. This resulted in extra minutes of excess emissions to escape from the battery. EPA notified SunCoke personnel of these concerns while on-site.
