Environmental Protection Agency officials said the agency would push for all 11 million diesel engines in the country to be retrofitted within 10 years in order to reduce their emissions of particulate matter, according to the Transport Topics newspaper on June 14. Margo Oge, director of EPA’s Office of Transportation and Air Quality, announced the goal at a Diesel Technology Forum conference here on June 3, and said the agency would work with fleets to develop financial incentives to accomplish the retrofitting. Estimates of what the retrofitting would cost varied widely, from millions of dollars to billions. All diesel engines from trucks to construction equipment would be included. “We’re in the middle of seeing the most dramatic transformation of diesel engines ever,” Oge said on June 3.
