The current New-Indy Catawba mill site originally opened in 1959 and began operation as a New-Indy subsidiary in 2019. Located on the Catawba River, New-Indy Catawba is a world-class integrated virgin linerboard and market pulp manufacturing mill. New-Indy Catawba produces a lightweight linerboard used for the outer surfaces of corrugated packaging, and high-yield unbleached pulp for other paper applications.

Daily Air Emissions Report

New-Indy is continuously monitoring hydrogen sulfide in various locations both at the Catawba Mill and in surrounding neighborhoods. The report below shows hydrogen sulfide levels as reported by New Indy. The report is updated daily.

From May 13 – June 29, 2021, the Environmental Protection Agency (EPA) reported the results of daily hydrogen sulfide samplings from 10 different locations in York and Lancaster Counties, South Carolina, and Union County, North Carolina. Those reports can be accessed via the Report Date dropdown menu on the top right-hand side of the map.**

Thereafter, New-Indy and the South Carolina Department of Health and Environmental Control (SCDHEC) each began collecting data from their own monitoring stations surrounding the New-Indy Catawba mill. New-Indy placed five of its monitoring stations in close proximity to terminated EPA monitors and SCDHEC installed three monitoring stations of its own. In the interactive map above, you can see the location of each New-Indy and SCDHEC monitoring station and their corresponding data. The full EPA and New-Indy daily reports can be accessed from the Daily Reports below. Full SCDHEC reports beginning on June 29, 2021, can be found HERE.

**Note: DHEC’s Catawba Express monitor failed on Oct. 14, 2021, and the monitor from DHEC’s Catawba River site was used to replace the Catawba Express monitor from Oct. 18, 2021-Jan. 9, 2022. The Catawba River monitor was restored on Jan. 10, 2022.

Dynamic Monitoring Finds Other Odor Sources

Monitoring has recorded elevated H2S readings at several locations

Expert Report Identifies Sources of Area Odor Complaints

Report conducted by engineering firm Trinity Consultants shows significant sources of odor in the region; majority unrelated to New-Indy paper mill

New-Indy Catawba announced the release of a new report, the New-Indy Catawba Odor & Complaint Analysis, prepared by an expert environmental firm, which concludes that New-Indy Catawba is not the source of odor in the Catawba region 79% of the time.

Trinity Consultants collected data and analyzed more than 5,600 air flow paths for complaint- and monitor-based events in the Catawba region between June 1, 2021, and Dec. 31, 2022. The report also identified more than 30 sites in the Catawba region other than New-Indy Catawba are potential sources of odor, including community and industrial wastewater treatment facilities, sanitary wastewater pumping stations, industrial operations, landfills, and farms.

Dynamic Monitoring Finds Other Odor Sources

New-Indy Catawba engaged Trinity Consultants to collect and analyze data to determine whether there is a link between odor complaints and hydrogen sulfide (H2S) data collected by monitors in the region. Trinity, an international environmental expert, was also asked to determine what were the most likely sources of odor.

Trinity identified more than 30 possible odor sources and concluded, that New Indy is not responsible for odor complaints or H2S readings in the community 79% of the time. As a result, and in the public interest, New-Indy decided that additional air monitoring for H2S should be conducted at the other possible odor sources.

2021 – 2024 Mill Operations Timeline

Prior to 2020, the New-Indy Catawba mill produced mostly white paper, which was used by customers to print magazines, catalogs and similar materials. Last year, New-Indy converted portions of the mill to manufacture unbleached containerboard, which is used by customers to produce various packaging products. The mill was completely offline from May to September 2020 during the conversion process. The first stage of restarting production began in December and by February 1, 2021, the mill had restored operations. On February 8, 2021, New-Indy Catawba LLC sent DHEC a letter notifying it that New-Indy Catawba began operations of all equipment except the No. 2 Paper Machine within 15 days prior to that letter.
