I may not know much, but I do know a good beer, where to get tasty pizza and the history of air pollution regulations.
Bush 1.0 signed the Clean Air Act Amendments of 1990. However, it was during the administration of Bush 2.0 that the United States Environmental Protection Agency issued the Tier IV emission regulations:
Tier 4 Standards. On May 11, 2004, EPA signed the final rule introducing Tier 4 emission standards, which are phased-in over the period of 2008-2015 [2786]. The Tier 4 standards require that emissions of PM and NOx be further reduced by about 90%. Such emission reductions can be achieved through the use of control technologies—including advanced exhaust gas aftertreatment—similar to those required by the 2007-2010 standards for highway engines.
