The new rule will require owners and operators of any installation to provide notices to the Department, local government officials, and the public whenever there is an incident or discovery of pollution at an installation within 24 hours. In addition, the owner and operator would be required to provide a subsequent notice within 48 hours that describes any potentially affected areas beyond the property boundary of the installation, and the potential risk to public health, safety, or welfare. The owners and operators are required to notify the Department, local government officials, and the property owner within 24 hours of becoming aware that pollution from an installation has affected areas beyond the property boundaries of the installation.
