SEATTLE (AP) — Washington state has issued $118,500 in fines for King County after finding more than two dozen sewer-overflow violations.

The Seattle Times reports the Washington Department of Ecology found 27 cases of wastewater discharge exceeding pollutant limits, five instances of unpermitted overflows and other permit issues in 2016 and early 2017.

Shawn McKone, of the ecology department, says the county and Seattle have been subject to consent decrees with the Environmental Protection Agency and the ecology department over sewage discharges.

King County is working to upgrade its wastewater system, which is combined with the city in areas with older infrastructure.

McKone says most of the violations involved discharges that had more chlorine than allowed, caused by problems at one of the four special combined sewer treatment plants.
