EPA and SC DHEC conducted a joint Clean Air Act onsite inspection of the New Indy Containerboard pulp and paper mill in Catawba, SC on Apr. 15, 2021. An EPA Geospatial Measurement of Air Pollution (GMAP) mobile laboratory was deployed to the New Indy facility and surrounding areas on Apr. 24. The GMAP is equipped with analyzers for a variety of compounds such as methane, BTEX - benzene, toluene, ethylbenzene, and xylene, hydrogen sulfide and carbon dioxide. It also has meteorological and global positioning system (GPS) equipment. The GMAP can conduct real-time monitoring and mapping of air pollutants while the vehicle is in motion, while taking meteorological conditions into consideration. In addition, EPA conducted a Clean Water Act inspection to determine the extent of potential violations from Apr. 26-27.

Working in collaboration with SC DHEC, NC DEQ and MCAQ, EPA evaluated data and information collected in the area and at the New Indy Containerboard facility to identify options for addressing the situation. Data from the GMAP is available here.

SC DHEC has established a website with information about the investigation and for citizens who may be impacted by odor concerns. The site includes a portal to document specific parameters and impacts. If citizens are experiencing significant or acute health concerns, please contact a health care provider.
