Maine solar developer fined for water pollution

MAINE PUBLIC • May 27, 2025

A solar company has been fined almost $236,000 by the Maine Department of Environmental Protection for polluting the Kennebec River during construction of a 5 megawatt array in Embden. Sediment runoff from a development by Tower Solar Partners LLC ran into the river from nearby Alder Stream, according to its agreement with the department. Erosion control measures were improperly installed, not maintained and overwhelmed, the department said. Thirty acres of soil was disturbed and unstable at one time, three times what the company was allowed under its permit. Multiple violations were reported to the department in 2022 and 2023. Tower Partners has since fixed erosion control problems and installed a stormwater maintenance system to help manage runoff. The company spent more than $722,000 to remediate the impact of noncompliance, in addition to the state penalty.
