This week the U.S. House of Representatives approved updates to the Toxic Substances Control Act. The 40-year-old piece of legislation, which provides EPA with authority to regulate commercial chemicals, was considered by many to be ineffective, including Capital Region Congressman Paul Tonko. The Democrat worked for more than two years to strengthen the law for consumers, but when the bill back came from the Senate, Tonko voted against the measure. Tonko explained his vote to WAMC's Lucas Willard.
