Activity and Use Limitation (AUL)
A legal document required for land that has been remediated for environmental contamination but in which there are conditions that must be maintained in order to prevent potentially hazardous exposure; restricts possible land use for the future and alerts future property owners that the property has potential risk for exposure; often an option used by landowners who are required by law to remediate their property, but who do not wish to incur the costs related to achieving a permanent solution without any limitation.
