Environmental Use Restrictions

The purpose of an Environmental Use Restriction (EUR) is to minimize the risk of human exposure to pollutants and hazards to the environment by preventing specific uses or activities at a property or a portion of a property.  There are two types of EUR, the Environmental Land Use restriction (ELUR) and Notice of Activity and Use Limitation (NAUL), both are recorded on the municipal land records.

Environmental Land Use Restrictions (ELUR) – forms, fees, and instructions

Notices of Activity and Use Limitation (NAUL) – forms, fees, and instructions

Emergency and Non-Emergency EUR Releases – allow for activities that are prohibited by EURs, such as excavation and utility work

The EUR Notification of Transfer (March 2022) - shall be used by the transferee to notify the commissioner within 30 days of the transfer of ownership of a parcel, or a portion of a parcel, subject to an EUR.
