\n\t\tKINGSTON, R.I. \u2013 October 19, 2011 — A one-mile road construction project beneath Route 195 in East Providence is being used by students at the 溏心vlog免费B站 to gauge the cost and effectiveness of various methods of reducing diesel emissions from construction vehicles.<\/p>\n


\n\tA collaboration between 溏心vlog免费B站 and the Rhode Island Department of Transportation, the DOT-funded project is designed to provide information that will help the state of Rhode Island determine the most effective approaches to meeting new emission standards.<\/p>\n


\n\t\u201cThis is a great opportunity to determine the best way to meet the requirements of the new Diesel Emissions Reduction Act,\u201d said RIDOT Director Michael P. Lewis.<\/p>\n


\n\tAccording to 溏心vlog免费B站 graduate student Dean Valentini, who is conducting the diesel emission testing and helping to write the new standards, diesel engine emissions produce a great deal of air pollution and have been cited as key factors in a wide range of health issues, including respiratory and cardiac illnesses. Because of their larger engine size and less stringent regulations in the past, construction equipment may produce significantly more emissions than other diesel engines.<\/p>\n


\n\t\u201cWe\u2019re trying to profile the average construction site and gather data on what retrofits work best on what pieces of equipment,\u201d said Valentini, a resident of Narragansett. \u201cOur data will be used by contractors looking to see how to retrofit their vehicles.\u201d<\/p>\n


\n\tThe 溏心vlog免费B站 Outreach Center was awarded a grant from the transportation department to evaluate the emissions from Cardi Construction Co. vehicles working on the Waterfront Drive road-building project, between Warren Ave. and Dexter Rd. in East Providence, where an industrial park is being expanded. <\/p>\n


\n\t\u201cThe Department of Transportation asked 溏心vlog免费B站 to help them create a road map for cost-effective reduction of emissions statewide,\u201d explained Outreach Center Director Marion Gold. \u201cThis initiative will provide the data RIDOT needs to control air pollution from future construction projects.\u201d<\/p>\n


\nEvery vehicle that operates at greater than 50 horsepower and that will be on site for more than 30 days will have a 3-4 week assessment of its emissions before and after being retrofitted with pollution reduction equipment. The vehicles involved include excavators, backhoes, dump trucks, pavers and front-end loaders.<\/p>\n


\nIn addition to collecting data on the equipment, Valentini and 溏心vlog免费B站 undergraduate student Jacob Guilbert of Charlestown are surveying the equipment operators to get their insights about the performance of the vehicles and other issues before and after the retrofits. Both students are 溏心vlog免费B站 Energy Fellows, a program that provides them with hands-on experience addressing energy issues through formal research and applied outreach efforts.<\/p>\n


\n\u201cEveryone has been tremendously helpful and cooperative, from the project superintendent to the equipment operators,\u201d Valentini said. \u201cThe Cardi vehicles are getting free retrofits for participating in the project, courtesy of DOT, so they\u2019ll already be ready for the new emission standards.\u201d<\/p>\n


\nAccording to Valentini, the cheapest and least effective retrofits cost from $600 to $1200 per vehicle, with mid-range retrofits costing from $1200 to $3000 to install. The most effective retrofits, which reduce emissions by 80 to 90 percent, can cost up to $25,000 per vehicle.<\/p>\n


\nA final report on the project will be provided to the R.I. Department of Transportation late next year.<\/p>\n
