Septic permits & rules in Union County: Union County has no county health department that issues septic permits — the county's Office of Health Management handles emergency preparedness and public-health coordination, while environmental health services are delivered by municipal and regional health departments. Per the county's health officers directory, for example, the Westfield Regional Health Department covers Cranford, Fanwood, Garwood, Mountainside, Roselle Park, New Providence, and Summit, and Rahway's department covers Berkeley Heights, Hillside, Scotch Plains, and Winfield — so any septic question in this largely sewered county goes to your town's health office. Details: Union County Office of Health Management (county-level coordination only; local health services are municipal/regional).
