First off, a prayer for all of the victims of the Louisiana flooding, take care.
Now, the recovery begins. OSHA has many resources on detailing how to stay safe in the subsequent flood cleanup. See https://www.osha.gov/dts/weather/flood/index.html
The flood cleanup may involve many hazards and may provide opportunities for violation of environmental disposal laws such as those covering demolition activities, debris cleanup and removal and hazardous waste operations and disposal. Only those with proper training, equipment and experience should conduct cleanup activities, especially those activities related to hazardous waste operations and disposal.
The flooding and resulting cleanup may also provide cover for the illegal disposal of hazardous substance and hazardous waste. We shall see if USEPA CID is watching carefully.
