Instead, the lawsuit alleges the Monterrey facility had for decades chronically contaminated neighboring communities with harmful carcinogenic gasses and particulate matter. The complaint also alleges that Defendants omitted to disclose that GrafTech had signed agreements with local authorities committing to improving the environmental performance of the Monterrey facility, but repeatedly failed to honor its commitments. The truth emerged over a series of partial disclosures, beginning first on Sept. 16, 2022, when GrafTech unexpectedly revealed that government regulators shut down the Monterrey facility. Mexican news outlets reported that the shutdown order was made in response to GrafTech's excessive pollution of carcinogenic gasses and particulate into neighboring communities.
