During 2023, we have found two incidents of fly ash bund breach in India. The first incident occurred in Waregaon under Kamptee taluka of Nagpur, Maharashtra in morning hours of July 19, 2023. The fly ashy pond belonged to Khaparkheda Thermal Power Station (KTPS) which is owned by Maharashtra State Power Generation Co Ltd (MAHAGENCO) a state-run power company.

The fly ash pond was brimful following heavy rainfall when a portion of its wall collapsed around 08:00 am. Resultantly, about 15 agricultural farms were flooded with toxic slurry damaging the crops. About 100 acres of agricultural land were filled with fly ash sludge which also entered the Kanhan River.
