ANCHORAGE - The state has withdrawn the Kenai River from its list of polluted waterways.
The Anchorage Daily News reports state regulators say the river is now meeting water quality standards.
The Kenai River was added to the list four years ago after high levels of petroleum compounds were found. The levels exceeded the state standards in July when recreational boats are on the river for the king salmon run.
Regulators tightened rules on the river, requiring outboard engines in July to be either four-stroke or direct fuel-injection two-stroke motors.
Tests in 2008 and 2009, after the rules were put in place, showed contamination no longer exceeded standards.
The removal of the Kenai River was announced Monday when the state released its annual water-quality report.
