of Intent plans, calculations, replication plans, narratives and supporting
data to the Commission.

B.
Replacement of Existing Septic Systems. For repairs and replacement of previously existing septic systems and/or cesspools, the leaching field/drainage area must be as far away as possible from any wetland, resource or jurisdictional area defined in § 340-1.3A. Repairs to a septic system to the original house to a lot which has been subdivided will require the new system to be at least 100 feet from any wetland.
