EPA Approves Engelhard Technology for Voluntary Diesel Retrofit Program.Business Editors ISELIN, N.J.--(BUSINESS WIRE)--July 11, 2001 The U.S. Environmental Protection Agency Environmental Protection Agency (EPA), independent agency of the U.S. government, with headquarters in Washington, D.C. It was established in 1970 to reduce and control air and water pollution, noise pollution, and radiation and to ensure the safe handling and (EPA EPA eicosapentaenoic acid. EPA abbr. eicosapentaenoic acid EPA, n.pr See acid, eicosapentaenoic. EPA, n. ) has approved emission-control technology from Engelhard Corporation (NYSE NYSE See: New York Stock Exchange :EC) for the agency's Voluntary Diesel Retrofit Program. The EPA approved Engelhard's DPX DPX Digital Picture Exchange DPX Digital Phosphor Technology (Tektronix) DPX Deep Penetrating Expanding (ammunition) DPX Digital Moving Picture Exchange DPX Di-N-Butyle Phthalate in Xylene DPX Duplex (TM) catalytic particulate filter for use in all heavy-duty diesel engines, like those in buses and trucks, in conjunction with ultra-low sulfur diesel Ultra-low sulfur diesel (ULSD) (also spelled “sulphur”) is a term used to describe a standard for defining diesel fuel with substantially lowered sulfur contents. fuel. The filters clean diesel exhaust of hazardous particulate matter as well as toxic gases such as carbon monoxide carbon monoxide, chemical compound, CO, a colorless, odorless, tasteless, extremely poisonous gas that is less dense than air under ordinary conditions. It is very slightly soluble in water and burns in air with a characteristic blue flame, producing carbon dioxide; and hydrocarbons. The approval means states will be able to obtain State Implementation Plan A State Implementation Plan (SIP) is a United States state plan for complying with the federal Clean Air Act, administered by the Environmental Protection Agency. The SIP consists of narrative, rules, technical documentation, and agreements that an individual state will use to (SIP) credits for heavy-duty diesels retrofitted with DPX filters. The EPA established the Voluntary Diesel Retrofit Program to create an incentive for states to begin cleaning up diesel pollution immediately, even though new federal emission standards for diesel engines do not take effect until 2004. Under the program, state air-quality planners can work with diesel fleet operators to choose approved emission-control technologies. States determine the amount of SIP credits to which they are entitled based on the pollution-control technologies implemented. "This technology gives bus and truck operators the opportunity to make existing vehicles run far cleaner," said Ed Stanczak, group vice president and general manager of Environmental Technologies at Engelhard. "Diesel vehicles have a well-deserved reputation for fuel efficiency and longevity. Unfortunately, they also have a reputation for soot and pollution. Now the technology is in place to change that negative side of the diesel." DPX filters typically reduce carbon monoxide and hydrocarbon emissions by more than 80% and particulate matter, or soot, by more than 90%. Based on patented technology, DPX filters are in use today on thousands of on- and off-road vehicles around the world. The technology is especially effective for controlling particulate matter, which has been implicated im·pli·cate tr.v. im·pli·cat·ed, im·pli·cat·ing, im·pli·cates 1.
