characteristic, such as the dumping of the contents of a basin or tank; the
known passage of a slug of hazardous substance through the facility; or any
other unusual circumstances.

conditions, facility design and operational controls will prevent a violation of
standards at the Compliance Boundary; or, (ii) submit a plan for the alteration of
existing site conditions, facility design or operational controls that will prevent a
violation of standards at the Compliance Boundary, and implement that plan upon its
