(a) We may take appropriate emergency action if there is a natural disaster or if an individual or entity causes or threatens to cause immediate and significant harm to Indian land. Emergency action may include judicial action seeking immediate cessation of the activity resulting in or threatening the harm.

(b) We will make reasonable efforts to notify the individual Indian landowners before and after taking emergency action. In all cases, we will notify the Indian landowners after taking emergency action by actual or constructive notice. We will provide written notification of our action to the Indian tribe exercising jurisdiction over the Indian land before and after taking emergency action.
