N.J. Stat. § App.A:9-43.19
A county governing body, through its office of emergency management or other appropriate office, agency, or department, shall establish a plan for issuing a Code Blue alert to municipalities, social service agencies, and non-profit organizations that provide services to at-risk individuals and are located within the county's borders. The county office of emergency management, or appropriate office, agency, or department, shall coordinate with municipal emergency management coordinators in municipalities with a documented homeless population of at least 10, as noted in the most recent Annual Point In Time Count, in developing consistent Code Blue alert plans throughout the county that provide for emergency warming centers during implementation of a Code Blue alert plan. This plan may be carried out by designated volunteer organizations. Volunteer-organized Code Blue efforts shall receive cooperation and logistical support from the coordinator, but shall operate autonomously, provided that they operate in response to an alert and pursuant to the Code Blue alert plan. L. 2017, c. 68, s. 2.
