Union County has 1,452 registered underground storage tank facilities in the national snapshot — gas stations, fleet yards, and other regulated fuel sites — holding 766 tanks in service and 5,132 tanks that have been closed or removed, plus 30 temporarily out of service. Over the life of the program, 1,228 fuel releases were reported here; 877 (71% of records) were investigated and closed with No Further Action, and 351 of those cleanup cases were still open when the snapshot was compiled.
