MOSCOW, Idaho -

The city of Moscow is being asked to cool the temperature of its sewage before releasing it into a creek that flows into Washington.

The city must cool the effluent processed in its wastewater treatment plant before releasing it into Paradise Creek to meet Washington rules and get a permit from the U.S. Environmental Protection Agency.

Les McDonald, the city public works director, says the temperature of the discharge has been a problem during the summer months. Moscow is located near the Washington border.

McDonald told the Moscow-Pullman Daily News the two best options are installing a chiller or directing the discharge into nearby wetlands before it flows into the creek.
