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.

June 30, 2022 – Statement from New-Indy Catawba:
New-Indy Catawba is pleased to have reached an agreement with the South Carolina Department of Health and Environmental Control to resolve issues of concern. New-Indy Catawba personnel have worked diligently with state regulators over the past year to develop a plan that will both benefit and protect the community surrounding the facility. The mill’s ongoing investment in cutting edge technologies has successfully kept hydrogen sulfide emissions negligible or zero for many months. This agreement will help ensure that future emissions continue to follow this trend.
Public Notifications
New-Indy will notify the public about operational activity that may result in changes in emissions from the Catawba Mill. Any such notices will be posted in this section.

2021 – 2022 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.
