New Jersey Statutes Title 48. Public Utilities 48 § 2-81

(1) The underground facilities of the State department or agency at the proposed excavation site comprise only traffic signals and lights or street and highway lights and their associated electrical feeds, control lines and traffic sensing loops;

(2) The State department or agency excavation permit is conditional upon the excavator notifying the One-Call Damage Prevention System; and

(3) The State department or agency provides the excavator with plans of the position and number of its underground facilities during the permitting process and agrees to cooperate on a continuing basis with the excavator in reasonable efforts to determine the location of such facilities, including notifying an excavator of any changes which may occur in the position or number of underground facilities after the initial issuance of plans to the excavator. However, the State department or agency may elect to mark, stake, or locate its underground facilities pursuant to the requirements of paragraph (2) of subsection a. of section 8 of this act.

If a State department or agency elects not to mark or stake its facilities under this subsection, an excavator who has conformed with the requirements of this act and all other applicable permit requirements, and uses reasonable care while excavating shall not be liable for damage to the State department or agency's underground facilities.
