Emissions Control Technology

Feb 20, 2026

Emissions controls comprise dry low-NOx combustors, selective catalytic reduction (SCR), catalytic oxidation, low-NOx burners with flue-gas recirculation for the auxiliary boiler, and high-efficiency drift eliminators on the wet cooling tower.

EPA's NSR record identifies two combined-cycle combustion turbines, an auxiliary boiler, emergency diesel equipment, and a 10-cell wet cooling tower with these controls.

Environmental-Compliance Milestone

May 1, 2026

The NPDES permit requires notification within seven days after discharge begins through Outfall 3IN00398001 and quantitative effluent characterization data no later than 13 months after permit effectiveness.

The compliance schedule applies to the wastewater characterization requirements and includes monitoring/reporting obligations; the permit also prohibits detectable priority pollutants attributable to cooling-tower maintenance chemicals.

Reported Emissions Quantity

Feb 20, 2026

EPA-listed greenhouse-gas emissions are 3,371,414 tCO2e per year.

The EPA NSR record lists GHGs expressed as CO2e at 3,371,414 and also lists annual quantities for CO, NOx, PM10, PM2.5, SO2, VOC, sulfuric acid, ammonia, and lead.

Reported Land Footprint

2023

Reported broader project-site area is approximately 122–127 acres, while the plant itself is reported to occupy approximately 25 acres.

Local project reporting gives different acreage scopes: a 127-acre site, a 122-acre site, and an approximately 25-acre plant footprint. These figures should not be added together. The 34.77-acre parcel is a specific owner-linked parcel, distinct from these broader site estimates.

Wastewater Discharge And Receiving Water

May 1, 2026

Outfall 3IN00398001 discharges to Mud Creek at River Mile 7.0; average permitted/design flow is 0.62 MGD and maximum flow is 1.1 MGD.

The discharge combines cooling-tower blowdown, low-volume process wastewater, and industrial stormwater in a cooling pond before release through the single outfall.
