N.J. Stat. § 48:3-126
During the course of the employee's employment, each employee of an entity, or subcontractor of an entity, who is responsible for installing lines or responding to service calls shall have an affirmative duty to report any line that the employee reasonably believes to be under the ownership of the employer, or in the case of the employee of a subcontractor, under the ownership of the entity for whom the subcontractor is engaged in work, and that the employee reasonably suspects to be abandoned, which line is attached to a pole or structure which the employee encounters during the normal course of installing lines or responding to service calls. If the employee of an entity who is responsible for installing lines or responding to service calls discovers an abandoned line during the normal course of the employee's work, the employee shall have an affirmative duty to either remove the abandoned line, if authorized by the entity, or report the abandoned line to the entity for further action.
