An alteration permit allows for the replacement of one component, either the disposal field or the septic tank, of a previously approved on-site wastewater treatment facility. Alteration permits are typically requested if:
One component (tank or disposal field) of the existing system is failing
The existing septic system will be insufficient for remodeling of or additions to the existing dwelling
Public Record Request
Public Record Request is required before submitting an Alteration Permit if the existing septic permit is unknown or not in the possession of the current owner.
