ANDROSCOGGIN VALLEY â A bill before the Maine Legislature to upgrade the classification of a 12-mile section of the Androscoggin River in that state is strongly opposed by the new owners of the Gorham mill as well as the communities of Berlin and Gorham. Submitted to the Maine Legislature in December, LD 676 calls for upgrading the section of the river from Gulf Island Dam near Lewiston-Auburn, Maine, to Merrymeeting Bay where it flows into the Atlantic Ocean. Currently classified as a Class C, the bill seeks to upgrade that section to Class B. Supporters of the bill said data shows the section already meets Class B standards 99 percent of the time. Upgrading the section would allow the entire river to be classified as Class B and would recognize the remarkable transformation of the river since it was considered one of the countryâs most polluted rivers.
