The last word on the modernization of Alcoa's Massena East plant came late Friday from the company itself.

Alcoa said $42 million in work will begin in June.

The company's announcement came exactly one week after word first leaked out that Alcoa had agreed to move forward with modernizing Massena East, thus preserving at least 900 jobs in the Massena area.

The deal to modernize the plant was 'officially' announced last weekend. What little uncertainty that remained concerned what the federal government would do about making Alcoa clean up the Grasse River, which it polluted for decades.

The federal Environmental Protection Agency made its decision official Friday morning: a $243 million clean up. It's a lot of money, but far less than some of the other alternatives the government was considering.

"Based on 15 years of scientific research, Alcoa believes the remedy is both protective of human health and the environment and effective over the long term," said Kevin Anton, an Alcoa vice-president, in a prepared statement.

Alcoa's statement came a day after St. Regis Mohawks blasted the government's actions.
