PORTLAND, Ore. (AP) - Oregon state regulators have fined the city of Portland $25,000 for illegally dumping chlorinated wastewater into the Columbia Slough last October.

The state’s Department of Environmental Quality says the fine is related to a 300,000-gallon discharge of chlorinated wastewater into the slow-moving slough, adjacent to the Columbia Wastewater Treatment Plant in north Portland.

Portland’s permit allows for dumping treated wastewater into the Columbia River.

The Oregonian reports (https://bit.ly/1Eekn2i ) that city Bureau of Environmental Services spokesman Linc Mann says the chlorination discharge occurred because of a faulty valve at the plant.

Mann says chlorinated wastewater typically travels from the plant north through a 2 ½-mile pipeline into the Columbia River, where the chlorine is treated before the wastewater enters the waterway.
