[41] In an opinion article, CEH's Michael Green (with co-author Christopher Gavigan) stated that the bill co-authored by Senator Tom Udall "would roll back hundreds of state laws, replacing them with a weaker federal rule that could put Americans at risk from toxics in our air, water, food and every day products for years to come.
