The assessment of a recent sewage spill in the Riverside Drive area of Mount Airy has revealed no resulting environmental damage.

City personnel were notified of the spill on Feb. 20, which involved an estimated 1,760 gallons of untreated wastewater entering an unnamed tributary of the Ararat River.

The incident was reported this week, with the city required to do so by state law and the provisions of its systemwide wastewater-collection permit.

Officials say the spill originated from a manhole located near railroad tracks off Riverside Drive. City personnel responded immediately and repaired the sewer line involved.

A subsequent inspection of the site determined it to be free of any environmental damage.

Under the law and its permitting requirements, the municipality must issue a public notification when a wastewater spill of 1,000 gallons of more reaches surface waters.

The N.C. Division of Water Quality was notified of last week’s incident and is reviewing the matter.
