At approximately 10:50 a.m. on Saturday, the Garrett County Department of Public Works – Utilities Division - Maintenance Division experienced an SSO in the area of 2405 Mayhew Inn Rd. The SSO occurred due to a mechanical failure with an air release valve on the sewer main located along Mayhew Inn Rd.
Workers moved quickly to minimize the impact of the SSO which flowed into a wooded area along Mayhew Inn Road, and, at approximately 12:15 p.m., the DPW-U tanker arrived on site to contain the leak. At approximately 1:00 p.m., DPW-U personnel isolated the malfunctioning air release valve and stopped the leak.
Based on the approximate rate of the spill, the estimated overflow volume was determined to be 4,500 gallons.
At approximately 1:30 p.m. on March 31, 2018, DPW-U personnel contacted the Garrett County Health Department (GCHD). Water quality sampling of the impacted area commenced at approximately 2:30 p.m.
