A facility has a spill of an extremely hazardous substance in an amount greater than its reportable quantity. The spill occurs on a concrete floor that is inside a facility building. Before the spill can be cleaned up, a portion (less than RQ) of the EHS enters the outside atmosphere through the window. Persons in off-site buildings report smelling the chemical.
Does the facility owner/operator have a reporting requirement under EPCRA, section 304?
