AUGUSTA, Maine (AP) Maine Gov. Janet Mills says that the dam manager at the center of her administration’s proposal to increase fish-passage standards on the Kennebec River should be able to meet state demands.

Bangor Daily News reports that the Maine Department of Marine Resources is revising its river management policy calling for dams to improve fish passage methods to allow more fish to reach spawning grounds at the Sandy River.

According to Brookfield Renewable U.S., the new fish passage standards would be “unachievable” and force dam removal.

Mills dismissed this notion Tuesday and said that Brookfield’s size should enable the company to comply.
