including the creation of nuisance conditions or failure of the utilization area to adequately assimilate
the wastewater, the Permittee shall take immediate corrective actions including those actions that may
be required by the Division of Water Quality (Division), such as the construction of additional or
replacement wastewater treatment and disposal facilities.
