Notices of Activity and Use Limitation

A Notice of Activity and Use Limitation (NAUL) is a type of Environmental Use Restriction (EUR) that complies with the requirements of section 22a-133o of the Connecticut General Statutes, section 22a-133q of the Regulations of Connecticut State Agencies, and the RBCRs. Unlike an ELUR, a NAUL is a notice recorded on the municipal land records that does not create an easement on the parcel granted to the Commissioner.  The purpose of a NAUL is to minimize the risk of human exposure to pollutants and hazards to the environment by (1) preventing the use of specified real property for certain purposes, or (2) prohibiting or requiring certain activities on such property.
  • Commissioner Approved NAUL - $5,000
  • LEP Approved NAUL - $1,500
