Vermont Wastewater permit: what it allows on a lot
Wastewater permit is Vermont law, and the official source is at dec.vermont.gov.
A new septic system or a change in use needs a state wastewater and potable water supply permit.
Whether it applies to one lot turns on where the lot is and what it is zoned; the city, county or state office named in the law decides. Mapped areas are approximate. This is a plain reading of public law with its source, not legal advice.
Free, no account. ParcelSheet shows the lot's mapped size, parcel lines and flood zone, and this law on the lot's Vermont sheet.
