About this object
The longest-serving Member of Congress in history, John Dingell, Jr. first chaired the Energy and Commerce Committee in 1981, when this portrait was made.
On this date, the House and Senate conferees finished their deliberations over competing versions of the Clean Air Act Amendments of 1990 introduced by Representative John Dingell, Jr. of Michigan and Senator Max Baucus of Montana. The result of several rounds of negotiations, the bill drastically broadened the responsibility of the federal government in pollution control and authorized creation of an "emissions trading" market "between industrial air pollution" sources. A compromise between environmental and automotive interests brokered by Dingell and Representative Henry Waxman of California, H.R. 3030 overwhelmingly passed the House on May 23, 1990, in a 401 to 21 roll call vote. Representative Dingell described it as “the most complex, comprehensive, and far-reaching environmental law any Congress has ever considered.” The original act, passed in 1963 but had not been updated since the amendments of 1977, in which Representatives Dingell and Waxman had also played key roles. President George H. W. Bush signed the 1990 amendments into law (P.L. 101-549) on November 15.
