At the Fauquier Livestock Exchange, U.S. Environmental Protection Agency (EPA) Administrator Andrew Wheeler followed up on his November 2018 announcement and took concrete steps to advance the Cleaner Trucks Initiative (CTI). Joined by U.S. Representative Denver Riggleman (VA-05) and a variety of stakeholders, the CTI rulemaking will establish new, more stringent emission standards for oxides of nitrogen (NOx) and other pollutants for highway heavy-duty engines. Through this Advance Notice of Proposed Rulemaking (ANPR), EPA is seeking input from the public and interested stakeholders. (Fuente: EPA)
