The Calvo Administration plans to take the feds to court is still a work in progress. It was during his State of the Island Address last year when Governor Eddie Calvo first announced he plans to sue the federal government for the harms at the Ordot Dump.
Calvo says he is now working with the Attorney General's Office on the matter, saying, "I've talked to our folks here in the administration with our attorneys, we're having further discussion with the Attorney General of Guam Elizabeth Barrett Anderson, she's shown more of a willingness to move and work cooperatively with us in our dealings with the federal government including in areas particular where we need to file legal action."
Governor Calvo says the legal action will pertain to the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (the Superfund). As you recall legislation was also introduced last year to take the feds to court.
It was discussed briefly on session floor, but sent back to committee where it eventually died with the end of the last legislative term.
